A user on reddit asked this once and he was not wrong, because
emacs does seem blocky compared to modern designs, which often employs
rounded corners, e.g for buttons:

https://www.webdesignerwall.com/wp-content/uploads/2010/04/button-preview.jpg

It could improve the square apperance if, for example, emacs provided some text
properties to specify rounded corners with custom radius for background colors.

Perhaps we should implement a mode that puts cosmetics on Emacs

Oh yes, because everyone chooses Emacs for hipster graphics
rather than for a free, sophisticated tool that lets you get
work done.

You might want to try Notepad on Windows 10 or something.

Or you might want to think about how to provide a way to accomplish that?

That's probably more in the spirit of free software than to send people to use a non free tool, isn't it ?

The thing is, you only care for decorations for a very
short time. After that, you want it as to the point
as possible.

I'm not a GUI Emacs user, but I give you half right
because last time I saw the default GUI Emacs on X it
looked like a Windows 95 application.

OTOH I'm unsure if Emacs does its own buttons. It does?
Or do they conform to the underlying look and feel, in
which case maybe one should configure the underlying OS
(e.g., the window manager, graphical/widget toolkit,
Xresources etc).

My opinion is we should make Emacs look _so cool_, and
then when people start using it they'll just remove
everything (but continue to use Emacs).

Visual impression matters. Often when I showed Emacs to people they commented on how dated it looks.

If Emacs' appearance can be improved by small things like providing support for rounded corners then it can be more appealing for people who care about visual appearance.

I think it's unfortunate if we assume that this is all bells and
whistles.  Graphical design elements can also improve usability.

I also don't know that it's helpful to assume that the rest of the
world will take the enlightened stance.  For example, I've always
assumed that many people use Sublime Text not due to any serious
feature comparison with Emacs, but because they like its "sleek look".
I don't suggest that we should imitate proprietary junk editor <foo>,
but we should realize that these things are not wholly unimportant.

When people say to me Emacs looks dated I often think the FSF should look for a graphics designer to improve the default appearance of Emacs.

Perhaps there are some who are sympatethic to the free software cause and they would do it even for free.

I think if we had the code for making the corners round, we'd use it
more or less unconditionally.  But we don't have such code, AFAIK, so
patches to add such capabilities to Emacs are most welcome.

Which won't help, because the Windows 10 look and feel doesn't include
rounded corners of windows, at least not by default.

I think the challenge would be in coming up with an approach which won't
make the terminal (non-gui) version drift from the GUI version too much.
Changing the button styles etc in the GUI menu and perhaps updating toolbar
icons etc is probably not too hard, but you cannot do much with things like
'buttons' in widgets etc (such as those used with customize) without having
to have completely different code for rendering in GUI and rendering in
terminal. This would potentially blow out maintenance and create two code
bases to manage and lets face it, one is more than enough.

I think part of the reason the GUI menus and toolbar might look dated to
many is that nearly all experienced and long-term users I know turn off the
menus and toolbar, so never see them. It has been years since I've used
either. For me, the only 'buttons' I see are the widget style buttons and
these are not really buttons - they are really text 'fake' buttons. I would
also be a little concerned about impact any attempt to change these might
have on performance (we already have quite a long thread about rendering
performance).

Just my 2 cents....

Maybe I'm missing something, but AFAIK we already have different code
for rendering this stuff in GUI and in text-mode frames. The GUI code
inserts an image and simulates the 3D "raised button" appearance,
whereas the text-mode code shows some ASCII art instead.

Or maybe I don't understand what differences you had in mind.

Well, I don't, FWIW.

Not sure what you mean by "text fake buttons".  We show a 3D
appearance on button widgets; if that's not real buttons, then what
should real buttons look like, in your opinion?

I don't think that is a problem, they already have different rendering
today.

I think the difficulty here is to look "contemporary" and yet fit every 
platform Emacs is run on. Button widgets look different on each. Even 
between GUI toolkits. And change between releases.

The other option, of course, is to look both modern and unique, but it's 
a harder proposition, especially without a graphical designer on the 
team. And this stuff gets outdated quickly.

There are only 2 variants: native buttons (provided by some toolkit)
or the ones we draw ourselves.  And there's no requirement that they
all look the same, I think: they should have the look-and-feel of the
toolkit being used.

I think "modern and unique" is a contradiction of terms nowadays ;-)

Exactly, and I presume it would be somewhat hard to emulate the GTK+
look under Athena/Lucid or Motif. Also, what problem would it solve?

"Modern" mostly means that everything looks like half-sucked candy.

These are implementation options. But either the "ones we draw 
ourselves" are designed to fit each platform, or they looks the same 
across platforms, with our personal look.

The latter option is sometimes taken by professional applications in 
which the user spends most of their time (e.g. Blender, or at least some 
of it earlier versions that I've tried).

In principle, I disagree. But it's difficult, and it's a balancing act, 
of course, between having them look distinct and interesting, but still 
familiar enough, and not too "tacky" (meaning, a design too exotic can 
become an eyesore after a while). It's a problem that bigger companies 
put whole design departments on.

For the original poster, because they might be used to running primarily a
distribution-installed version of emacs: the code for unix-based GUIs has
supported a variety of these sorts of elements for a very long time,
depending (currently) on whether you build emacs with the Athena, Lucid,
Motif, Athena3D, or gtk[,2,3] toolkits. Under macOS, one has the ns and mac
ports, and under MS Windows, it uses the local gui toolkit (which I
believe is the core W32 look and feel, not the frequently-shifting WPF,
Windows Forms, Metro, UWP, etc. standards).  Even within these systems,
there are options inside emacs for giving buttons a 3D look or not, and
there are many packages that add icons to emacs' display (via fonts, as far
as I can tell) that can 'spiffy up' emacs considerably.

It would probably be helpful for emacs' adoption if some of these gui
enhancements could be added to emacs and/or ELPA more directly. To be
specific, it would perhaps be helpful for emacs new-user adoption if people
didn't feel the need to adopt a large integrated package like Spacemacs or
DOOM emacs just to get graphical niceties -- not because those bundles are
bad, but because they add a *lot* more than just the gui enhancements. The
past couple years has seen a bit of an explosion of packages like
better-defaults or "starter kits" that aim to improve the new-user
experience without such a large overhead, but those still require getting
emacs from somewhere other than GNU or the standard distrubutions, which is
an extra hurdle.

I would be happy to help with such an effort, but I'm unsure what sorts of
changes would be acceptible to "core emacs", and I don't personally have
anything major to add to the existing set of third-party starter kits or
mega-bundles. If someone here had a clearer idea, that would be helpful.
Maybe the first step is to try to get all-the-icons (
https://github.com/domtronn/all-the-icons.el) or an analogous package
included in emacs?

Hope that helps! Thanks,
~Chad

I use the official windows build and it looks like this which is
definitely not how buttons look in windows dialogs:

The native buttons don't have a thick shadow like this.

That's the problem. What's hip today is passé tomorrow. The "modern"
look of Windows 3.1 is considered ancient and dated today. But do
today's GUIs offer more (or perhaps less!) user value?

In my initial attempt to be sarcastic, I unfortunately took too
extreme a position. so I'll say now that there is nothing wrong with
an Emacs GUI that provides true user value, and if it looks nice,
that's a plus. (But I too go to the extreme of pure text, no frills,
touchpad disabled, etc. ... it's what works for me.)

However I would (humbly this time) suggest that whatever is done in
terms of appearance not interfere with the things that make Emacs the
tool that it is.

1. It will take work.

2. The code to interface Emacs to X-based GUIs needs rewriting by an
expert, and has needed it for decades.  Until it gets that rewrite,
changes in it are likely to break something.

3. We may not have any developers who are experts on that area

I won't argue with that -- but I have a feeling that the changes
that would help are deeper issues than the shape of corners.

Perhaps that is true.  Or perhaps its graphical interface is
substantively more natural than that of Emacs.  In Emacs, our
graphical interface is constrained by historical compatibility
and making it more natural is difficult.

Another question about them: are they among the segment of users for
whom the investment of learning Emacs would pay off?

Allow me to interject: how modern does my Emacs looks (see attach)?
that is just using some packages available at MELPA (sad, I know;
ideally such cosmetic stuff should be available in ELPA and/or be ship
with new versions of Emacs and turned on by default).

We don't use the native buttons on MS-Windows.  The only native
widgets used on MS-Windows (AFAIR) are the menu bar and the scroll
bars.

I don't really know the answer, but I'd like to remind all of us that
there's a lot of "propaganda" out there telling everyone to turn off
GUI features such as the menu bar and the tool bar.  The network is
full of personal init files that "proudly" do that, and forums like
Reddit are full of such advice to every newbie who asks about
configuring their Emacs.  It is hard to be enthusiastic about making
these features more modern when the community seems to be divided on
whether they should at all be present.  IMO, we should first get our
act together and decide whether these features are important, and then
speak up according to those decisions when we see advice to the
contrary.

Interesting. I sort of assumed Emacs looks the same everywhere and
thought all emacs users saw these old fashioned buttons if they
open up Customize which I see on Windows.

But if emacs uses native buttons elsewhere then it means Emacs
can look much better on other platforms, at least as far as
we consider GUI widgets.

Wouldn't it make sense to use native controls on every graphical
platform?

Surely unifying under a single cross-platform toolkit like GTK+ would
avoid having this complexity. I still run lucid because there is a long
term bug in the GTK engine which I don't understand but gets loudly
reported whenever you run it. I'm not sure if this is down to the
toolkit or the thunking Emacs has to do to have a common command loop
shared between it's GUI and terminal invocations?

There is a danger in assuming everybody wants their experience to be
like ours. My personal config may be fairly austere and minimalist but

GTK+ is not cross-platform, it works only on some of the platforms we
support (and is not an easy toolkit to work with, based on our
experience).

This is because GTK+ has a bug that AFAIR they don't intend to fix
because they don't consider our use of GTK+ important enough (or
correct, for that matter).

Not sure what thunking did you have in mind.  The handling of input in
Emacs should consider both GUI and TTY inputs, since otherwise you
will be unable to have both GUI and TTY frames in the same session,
and the likes of "emacsclient -t" won't work.

Emacs's look-and-feel varies depending on the toolkit used to build
it.  So it cannot look the same everywhere, not in every aspect of the
GUI decorations and widgets.

I think you are generalizing too much here.  We don't use toolkit
widgets for every element of our GUI.  So some "buttons" are native
(for example, the tool bar of the GTK+ build), while others are not.
Which toolkit build uses what widgets where depends on what the people
who wrote the related code did, not some policy decision.  And
sometimes we even have options to let users choose between native and
Emacs-implemented GUI elements, like the x-gtk-use-system-tooltips in
the GTK builds.

> Wouldn't it make sense to use native controls on every graphical
> platform?

That has advantages, of course, but also some disadvantages.
Complexity of code is one of the disadvantages, because some widgets
of some toolkits require special code (like separate input loops) to
be able to use them, or because they have some limitations (e.g., GTK
tooltips cannot display images, at least the way we invoke those
tooltips.

I think part of the problem with things like the menu bar is that if you're
using emacs at all you are demonstrating a willingness to tolerate:

* A UI that doesn't look or behave like any other application
* Keyboard shortcuts inconsistent with every other application
* A bizarre ancient vocabulary inconsistent with every other application.
e.g. no Microsoft word user has ever considered themselves to have opened a
"buffer". They open "files". They move "windows" around, not "frames." They
cut and paste not kill and yank, etc.

You are basically making a commitment to being or becoming a power user. I
certainly would not have put up with it if I didn't think it was going to
save me a lot of time as a software developer (and it does, everyday). I
doubt anyone invests the mental effort to deal with learning emacs nowadays
unless this is their goal. If you just want to do "casual" text editing
emacs is a very weird choice in 2020.

If you're a new user the idea that seeing kill and yank in the menu bar as
options helps discoverablity doesn't really hold when already nothing is
named the way you expect or acts the way you expect. If you're an
experienced user, then I would guess that like me C-h f,v,k and blog posts
are 99% of your discoverablity experience.

That's definitely something we should keep in mind, but what on earth
does it have to do with turning off the GUI elements of the Emacs UI?
Or with the advice to newbies to turn them off?

I suggest to take a good look at the menu bar, since we don't have
Kill and Yank there for a long time.  We have Cut and Copy and Paste
instead.

The tool bar especially would work better if it looked/acted like it were native.

I thought Customize buttons are native on some platforms, but I checked,
and now I see they are just faces.

It could improve appearance quite a lot if someone with a feel for graphical
design took a look at faces and created some more modern looking defaults.

Though, of course, there is only so much you can do with colors to improve the
graphical appearance.

E.g. checking the GTK buttons they apparently have some small border and,
of course, slightly rounded corners:

My guess would be that the GTK+ bug will never be fixed.

I just wonder if it wouldn't be consequent to make multi-tty features
and GTK+ mutually exclude each other. Alternatively, move to Qt instead
of GTK+ (though I can see the NIH argument there).

That's a great point.  My personal config has the tool bar turned off.  Part of the reason is that with my desktop configuration (using a dark theme) the icons are unreadable (dark grey on a dark background, see attached screenshot), and part of the reason is that I didn't like the look of the icons in some of the (few) modes that use the tool-bar (e.g. in message-mode).  (Also, I seem to have a bug with the tool-bar: when I hover over the first two buttons it doesn't show a tooltip, but if I click on of them and close the file-selection dialog before hovering over the button again I do see a tooltip).

On the other hand, I have written some modes that override the user configuration and re-enable to tool-bar with mode-specific functions, and I haven't received complaints (see e.g. the attached screenshots).

I suppose I can guess what you mean by "looking"
native, but not what "acting" native means.

My impression is that different apps outside Emacs
can have radically different kinds of tool bars,
both wrt action and look & feel.  And this is so,
even for apps on the same platform, where they are
perhaps all "native".

IMHO, the Emacs tool-bar is something that it makes
sense - at least optionally - to pop up on demand,
rather than take up a fair amount of screen real
estate.

My library tool-bar+.el implements one way of doing
this - by having a menu-bar pseudo-menu `Buttons',
which, when clicked, shows the tool-bar only for one
operation.  Other ways of doing this or something
similar are possible, of course.

https://www.emacswiki.org/emacs/ToolBar#ToolBarPlus

(That library also gives you the possibility of
showing the tool-bar only on particular frames,
rather than showing it on all frames or not showing
it on any frame.)

I doubt people will accept the former.  As for the latter: volunteers
are welcome, of course, but Qt is a C++ toolkit, which means another
non-trivial obstacle.

Sometimes we do and sometimes we don't.  With my current emacs configuration, for example, I get buttons that look like this on graphical frames:

 Operate on all settings in this buffer:
 [ Revert... ] [ Apply ] [ Apply and Save ]

I think this is due to custom-raised-buttons being nil, which happens if cus-edit gets loaded too early in an Emacs server, as in the following example:

  echo "(require 'cus-edit)" > ~/.emacs
  emacsclient --alternate-editor="" --create-frame 

In the resulting graphical frame, customize buffers won't use 3D buttons.  Tim, what is the value of custom-raised-buttons in your session?

Should I open a bug report?

I think it's a bug in your ~/.emacs, so a bug report will hardly solve
it.

Well, I certainly turn all that stuff off, but I've been using Emacs
for decades, and I'm comfortable enough now (and I also use Helm). In
earlier days I definitely made good use of the toolbar and menus. They
were not especially pretty (that didn't concern me), but they helped
me learn much more quickly.

I would, however, /never/ recommend to a newbie to turn off the menu
bar etc. You should only get to Emacs "minimalism" (a) after a long
enough time to be quite comfortable and (b) if it suits your style of
work.

I think there is a misunderstanding.  The recipe I posted above is self-contained and reproduces the issue.
The problem is that custom-raised-buttons is initialized once and for all to a value that depends on whether the current frame when cus-edit is loaded is a graphical frame.  Then all other frames, graphical or not, use that value.

Of course.  Which is why I think I understand the issue.

Initialization of stuff that depends on GUI frames and should work in
client frames needs to be done in server-after-make-frame-hook.

Same here, though I would not force that to new users.  (Recommend,
perhaps.)

Interestingly, I am almost sure that the toolbar was turned off by
default when I started using Emacs (v18 or 19, I don't remember).  IIRC,
when after some upgrade the toolbar appeared, I turned it off at once.
Does that seem possible or is my memory wrong?

OTOH, I learned Emacs by first using the tutorial and then reading most
of the manual, so I probably have a rather atypical history wrt that.

They reportedly appear when you invoke M-x report-emacs-bug

Feel free to point us to GPLed icons that can be incorporated in
Emacs.  At the time, the situation was nowhere as easy as you imply,
but maybe things have changed since then.

Aren't the icons used by GTK/Gnome GPL licensed? I assumed they
were if GTK/Gnome uses them.

I think I don't understand this part :/

To be clear, the bug that I'm talking about is that, when using the Emacs server, requiring cus-edit during initialization causes buttons to be displayed as text, not as 3D buttons.
It's really easy to run into this without realizing it.  For example, installing the `validate' package from Elpa will do it:

  emacs -Q --eval '(setq user-emacs-directory "/tmp/emacs-sandbox")' \
    -l package \
    --eval "(package-refresh-contents)" \
    --eval "(package-initialize)" \
    --eval "(package-install 'validate)" \
    --daemon

  emacsclient --create-frame # This frame doesn't use 3D buttons in e.g. customize-face

Alternatively, installing the package manually and putting `(require 'validate)` in your .emacs to be able to use (validate-setq tab-width 4) will also cause issues.

What am I missing?
Clément.

Following up on my previous message, I'd argue that the following is also a problem, btw:

  emacs -Q --daemon
  emacsclient --alternate-editor="emacs -Q" --nw # In this window, run M-x customize-face RET bold RET then exit
  emacsclient --alternate-editor="emacs -Q" --create-frame # In this window, run M-x customize-face RET bold RET

The second customization window doesn't have 3D buttons.

Log out hanging after X-forwarded emacsclient [Was: Closing displays GTK+ bug]

[Adam Sjøgren via "Emacs development discussions.]

Inspired by the mention of the old GTK+-bug, I did a build of emacs like
this:

  ./configure --without-pop --with-cairo --without-dbus --with-x-toolkit=lucid && make bootstrap

And then I started Emacs on the machine:

  machine1:~$ /usr/src/emacs/src/emacs -Q --eval '(server-start)'

On another machine, I ssh'ed to the first machine, with X-forwarding
turned on, and started emacsclient:

  machine2:~$ ssh -X machine1
  machine1:~$ /usr/src/emacs/lib-src/emacsclient --create-frame /tmp/test.txt
  Waiting for Emacs...

And got an X frame displayed on the screen of machine2, as expected.

When I then end emacsclient with C-x # I'm back at the prompt. If I run
"exit", the prompt is hanging, where I would expect to be logged out of
machine1 and returned to machine2. Only after I press control-c do I get
the prompt back:

  machine1:~$ exit
  ^C
  machine2:~$ 

(When I press control-c, the message "Connection lost to X server
'localhost:10.0'" is displayed in the mini-buffer in the Emacs frame on
machine1.)

I thought this "hanging" was related to the display closing GTK+-bug,
but this is with lucid. At one point, I think, I read that it was a
dbus-related thing, but I also turned off dbus.

How do I avoid this hanging/having to press control-c?

No reason indeed.  I started to implement rounded corners for tabs
by adding a new :style to :box face attribute with drawings implemented
like in x_draw_relief_rect but had no time to finish before the
emacs-27 pretest.  But it looks like a wrong approach anyway.

But when someone will properly implement rounded corners for buttons
they could be used for tabs as well.

i'm not sure about other ssh implementations, but i've always suspected
a buglet in  ssh(1) or sshd(8).  or maybe in libx11?

perhaps some resource was stored in the x server and ssh holds the
forward open until it is released?

I wrote a longer post about this topic on the emacs reddit recently, but a
short summary would be: What Eli said, plus some. There is no good
cross-platform GUI toolkit (free or otherwise), and the closest the
software world has today is Electron (which still doesn't cover everything
emacs supports). I realize that there are some partial solutions that
advertise themselves as cross-platform, but if you poke at them with a
moderately keen eye, they collapse quickly. As a practical matter, this is
a big reason that some of emacs' biggest competitors these days are based
on Electron (VS Code and Atom) and Java.

It was very hard to work out a set of default faces that worked
reasonably.  We had to make change after change till everyone
was happy with it.

I think that the help of a graphics UI designer could enable us to
make an improvement _if_ perse is capable of working within the

Qt has a fatal flaw (from our point of view) -- it is released only
under GPL versions 2 and 3.  If we ever need to make a GPL version 4,
we will want to advance Emacs to GPL 4-or-later.  If we depended on Qt,
we would be blocked from upgrading the license version.  We must not
get into that difficulty.  

So we must avoid using Qt.

Someone™ needs to invest the time and effort to figure out the legal
issues, find the icons that we want out of those which are legally
fit, and post the resulting information.  We did that process at the
time (AFAIR, quite a few of our icons come from Gnome/GTK), and it
wasn't easy.

Alternatively, someone could create our own icons, in which case they
could be even prettier than the ones pointed out here.

In any case, this is a non-trivial job, and volunteers are most
welcome to do it.  I don't think anyone is happy about the icons shown
on the tool bar by Message mode; the only reason we use them is that
we couldn't find better ones that are free and suitable for inclusion
in Emacs.

Thanks.

What was the problem exactly? Gnome is a venerable free software
project, so I assume they pay attention to proper licensing.

Isn't their icons safe to use if they publish them with a GPL2 license?

IIUC, only a few add-on components of Qt are licensed under the GPL.
Its core libraries are licensed under the LGPL, version 3.

Sure, why not?  However, the entry would be more useful if it listed

I'm sorry, I don't remember.  This was many years ago.  Please look in
the archives.

IANAL, but I think it has to be GPL v2+ at least.  And perhaps we
would also need the copyright assigned to the FSF.

Once again, this is a non-trivial job to do, a discussion in a mailing

"Suitable" in all the senses mentioned in this discussion.  Including,
but not limited to, aesthetics.

No, it's only because the first use of customize was on a tty frame.
The same happens if you

    emacs -Q -nw
    M-x customize-face ...
    M-x make-frame-on-display ...

As Stefan pointed out, this isn't due to the daemon.  But even so, starting Emacs as a daemon shouldn't break 3D buttons.

A few messages ago, the following discussion happened:

I was just pointing out that in may cases we don't show a 3D appearance on button widgets.  You also wrote:

The code is here:

(defcustom custom-raised-buttons (not (equal (face-valid-attribute-values :box)
					     '(("unspecified" . unspecified))))
  "If non-nil, indicate active buttons in a raised-button style.

	 (setq custom-button-mouse

	 (setq custom-button-pressed
	       (if value
		   'custom-button-pressed
		 'custom-button-pressed-unraised))))

This definition is evaluated once and for all, instead of once per frame.  Isn't that a bug?

I don't know.  AFAIK, we don't have infrastructure for deciding when
stuff like that needs to be re-evaluated and how to use different
results for different frames.  If someone wants to work on such
infrastructure, I think it will bring us a step closer to being able
to support different GUI frame types (like GTK, w32, NS, etc.) in the
same session.

I may be missing something, but I don't think such infrastructure is needed here — we already have most of what's needed with conditional faces.  The attached patch gets us 90% of the way, with the only remaining issue being wrapping buttons in square brackets on text terminals.

We'd also need a similar trick for check-boxes and the like.

Faces were always per-frame (although when you customize a face, it
changes on all frames), but faces are just the tip of the iceberg.
The general problem with GUI features is much wider.  I thought you
were talking about the more general problem.

Why a separate face, instead of a separate definition of the same face
for non-GUI displays?

Anyway, the condition should not be on frame types, but rather on
capabilities, IMO.

I'm talking only about the OP's problem, which was that buttons were not displayed in 3D.

To be able to honor the custom-raised-buttons setting.  I wouldn't design it that way, but that's where we are.

> capabilities, IMO.

Agreed.
Do you know how the problem with square brackets could be solved?  Currently the custom-raised-buttons setting is used to chose a face and to decide whether to insert square brackets around buttons. Is there a clean way to make these brackets display only in text terminals?

Can you give some examples?

I can't think of any program I have seen the same thing happen with.

It is also uncommon to ssh to a machine, ask an already running program
to open a window on the remote screen, close the window and log out,
without quitting the entire program.

But that's of course exactly what I want to do with Emacs.

Sounds likely, so I just need to figure out what it is and how to avoid
it ;-)

(Running emacsclient with nohup exhibits the problem, so it isn't as
simple as stdin/stdout/stderr.)

Me too, but fortunately this isn't a question about custom, it's a question about features about the display engine.  

There is a way to change the color, backgorund, etc. of a bit of text depending on the properties of the display it is on, through the face-specs of defface.  Is there a similar facility for showing or hiding a piece of text depending on properties of the frame it's shown on?  I tried using a conditional 'display property, but that doesn't seem to work.

I don't think I understand the problem.  Faces can have different
definitions on different frames, so what is the problem, exactly?

The problem is to indicate that a string is a button on a text terminal.  Currently, custom does this by writing the string "[button]" with an underline on text terminals, and "button" with a raised look on graphical terminals.

This is done by inserting different text in the buffer depending on whether the display supports the `:box' face property.  Because of this, a customization buffer created on a text terminal shows "[button]" instead of "button" when displayed on a graphical terminal.

The question is: is there a way to insert something in a buffer that will display as "[button]" when shown on a text terminal and as "button" when shown on a graphical terminal?
I thought of using something like (propertize "[" 'display '(when (display-graphic-p) . "")), but it doesn't work well: when the buffer is shown on two frames (one graphical, one non-graphical), it doesn't look right in both.

I did not.  Interesting thought! But since I need the "[" on graphical terminals, I'd use a replacement spec that says to show an empty image on graphical terminals, is that right?

> Or a window-specific overlay?

Interesting! But wouldn't I need to re-create the overlays every time the buffer is displayed in a new window?

> And btw, in the conditional 'display' spec, did you call

Yes, here's the full test:

(defface my-button
  '((((type x w32 ns) (class color))
     :box (:line-width -1 :style released-button)
     :background "lightgrey" :foreground "black")
    (t :inherit underline))
  "Button face"
  :group 'flycheck-faces)

(with-current-buffer (get-buffer-create "button")
  (insert (propertize "[" 'display '(when (display-graphic-p (selected-frame)) . "")))
  (insert (propertize "button" 'face 'my-button))
  (insert (propertize "]" 'display '(when (display-graphic-p (selected-frame)) . ""))))

I put this code in button.el, then I run emacs like this:

  emacs -Q -nw -l button.el 

I display the buffer in the terminal; it looks like this: [button] with "button" underlined

Then I use M-x make-frame-on-display :0 to show the same buffer in a graphical frame.  I see this: [button] with a 3D face on "button".  If I move the point, the brackets disappear on both frames (the terminal one and the graphic one.  If I switch back to the terminal frame, the brackets reappear on both frames.

My guess is that the (selected-frame) at the time the code is run might
not be the one you think.  Maybe we should change/fix that (we had the
same problem when computing the mode/header lines).

Doesn't look like it, from this test:

(with-current-buffer (get-buffer-create "button")
  (insert (propertize "[" 'display '(when (and (message "[%f] On frame %S: %S"
                                                        (float-time)
                                                        (selected-frame)
                                                        (display-graphic-p (selected-frame)))
                                               (display-graphic-p (selected-frame))) . "graphic")))
  (insert (propertize "button" 'face 'my-button))
  (insert (propertize "]" 'display '(when (display-graphic-p (selected-frame)) . ""))))

Clicking in the graphical frame reevaluates in both, and the terminal one does see nil.  Clicking in the terminal frame reevaluates only there.  In both cases the display is updated in all windows (on all frames).

Re: "Why is emacs so square?"

[Ahmed Khanzada]

Joseph, a few things come to mind from reading your email:

1. Terminal-based Vim is not like a modern application, yet is more
popular than Emacs.

2. The audience for Emacs are people interested in using free
software and Lisp to extend their text editing experience. Very few of
these will be "casual editors", and in fact the FSF provides libre casual
editing software through the GNOME project.

3. If Emacs was to become a "modern" app tomorrow, an editor extended
in Lisp still only has appeal for a minority of programmers, much like
the Lisp language itself. Most programmers looking for easy and modern
experiences will likely stick with Atom and Sublime.

4. Most of the push for a "modern look" comes from the desire for Emacs
to play more nicely with proprietary platforms. Rather, the goal of
Emacs is to support platforms like GNU/Linux. Platforms that respect
your freedom, and also do not push a corporate UI/UX vision of "modernity".

(Perhaps if we do move forward with modernization, we should think of
modernization in the context of something like GNOME rather than MacOS
or Windows. Surely Emacs could be a better citizen of GNOME.)

5. Given that many of the people complaining about how Emacs looks are not
submitting patches to fix the problem themselves, resources would be diverted
from actual functionality to "modernity".

6. By the time we do major code refactoring "modernizing" Emacs on the
major proprietary platforms, what is "modern" has now once again
changed, and our resources were put towards a project with a poor return on
investment.

Basically, I don't see a "modernizing" project playing out well. We will
spend extensive time and energy on a moving target, and even if we
succeed, our Lisp-based vision still has limited appeal. Additionally, I
don't think "modernizing" Emacs advances the cause of free software,
given that there are other more popular casual libre tools for text editing
that individuals can use.

I was going by the information in Wikipedia, which said GPL 2 and 3.

LGPL 3-only has the same problem.  LGPL 3 is GPL 3 with some specific
extra permissions for linking with programs not under GPL 3.

Due to those extra permissions, linking Qt with GPL4-Emacs won't
violate the license of Qt.  But linking GPL4-Emacs with Qt would
violate the license of GPL4-Emacs, unless Qt qualifies as a "system
library".

If those Qt libraries are under LGPL 3-or-later, there will be no
problem.

Gnome shell also has a development list. A way forward can
be to post to that list politely asking for a workaround until
the issue is solved:

The developers may be more likely to respond if the asking

The Gnome icons at https://commons.wikimedia.org/wiki/GNOME_Desktop_icons
are apparently for an earlier, obsolete version. I downloaded the indicated
version (gnome-icon-theme 2.20.0) and the files in it were last changed in 2007,
but the icons still look nice.

Emacs could benefit from using these icons too, even if they are obsolete,
because they are consistent and look good.

For example, the popularity of Vim is unlikely to be based on the

Nearly 20% of programmers use vim, and around 3% use Emacs.

Visual Studio Code has 54%.

That is fair enough. But for extensible editors, features are built by a
small group of folks interested in that sort of thing. A more
"mainstream" language usually means more extensions which means more features.

I suppose this is a pure assumption on my part based on my anecdotal
experience. I hear more comments about Emacs not being a nice MacOS or
Windows application than a nice GNOME application, but that is just anecdotal
evidence, and is certainly skewed by the popularity of those platforms.

I disagree.  The amount of extensions to an editor reflect the popularity
of the editor, not whether or not the editor's extension language is
"mainstream" or not.

Plus, Emacs Lisp has a bunch of nice goodies for Emacs, since the
language itself is seamlessly integrated with the editor it extends
(such as text properties in strings, buffer-local variables, et cetera).

I would also go as far as to say that writing Emacs programs is far
easier, and involves far less boilerplate, than writing extensions for,
say, VS Code:
-------------------------------------------------------------------------------
var setting: vscode.Uri = vscode.Uri.parse("untitled:" + "C:\summary.txt");
vscode.workspace.openTextDocument(setting).then((a: vscode.TextDocument) => {
    vscode.window.showTextDocument(a, 1, false).then(e => {
        e.edit(edit => {
            edit.insert(new vscode.Position(0, 0), "Your advertisement here");
        });
    });
}, (error: any) => {
    console.error(error);
    debugger;
});
------------------------------------versus------------------------------------
(with-current-buffer (find-file "~/summary.txt")
  (set-window-point (selected-window) (point-min))
  (insert "Your advertisement here"))
------------------------------------------------------------------------------

A better language wins extensions, not a "popular" language, and Emacs
Lisp is definitely more suited to extending editors than TypeScript.

I certainly agree with everyone that Lisp is fantastic, and that
extending Emacs with Emacs Lisp is a great pleasure. And that Emacs Lisp
is certainly superior to any other alternative that I know of. So please
don't think I would want Emacs to use anything other than Lisp.

However, despite Lisp being extraordinarily powerful (truly a "better
language"), no dialect of Lisp is a top 10 language. It seems unlikely
to me that there is no correlation between that fact and the popularity
and accessibility of Emacs.

However, even if there is a correlation, determining the exact nature
and extent of correlation is difficult.

I think you've stated the arguments very well.  There are a couple of
points where I would say something less strong.

If Emacs were 100% as convenient and attractive as other editors,
it is possible that a lot of users would use it.  30 years ago,
the user profile of Emacs was much broader than it is today.
It would be good to make this happen again.

But that would require a number of changes, and I don't think that
round corners would get us close to there.

Thus, I think your point 3 is not valid in the universal sense that it
is presented in, but it is valid for the this particular issue.

If there are people who want to work on rounded corners, and assuming
they do a good job, I won't argue against it.  But if you want
to attract more users to Emacs, I think there are more important
areas for improvement.

A new user might well think of Emacs keyboard commands as "shortcuts",
carrying over the concepts that perse has learned in using other
programs.  When it comes to understanding what new users think,
we need to know what concepts they use.

But those characters are not really "shortcuts".

That is incompatible with every version of the GPL.  If the icons

If the icons would NOT be part of the program, Emacs, then there
is no conflict.

The Emacs distribution contains many works, including textual, art,

Paul Graham has an insightful article here:
http://www.paulgraham.com/avg.html;  IMO, it's worth reading.

Plus, if you look inside the domain of "text editor extension
languages", Emacs Lisp is definitely one of the top-10 (assuming there
are 10 at all), and is also probably the most integrated one.

You can also extend Emacs in languages other than Emacs Lisp (the native
module support comes to mind), but at that point you're giving up
exactly what makes Emacs great.

So, can we include them as "NOT part of the program"?

I think it's the usual approach when it comes to assets. And icons are 
not code.

I would personally say that several of the starter packs (Spacemacs and
Doom immediately come to mind) are "attractive" and "modern", and don't
really sacrifice any functionality to achieve that.  Spacemacs is also
very easy to set-up and use.  (Doom's also getting there).

I'm working on something that uses GTK foreign rendering to draw button

in a usable state soon (right now it only works on top of another set of
patches I'm working on that make Emacs a pure GTK app).

Maybe it would be nice to have era-based user experiences. Like a 70's UI package, a 80's UI package, etc. That way it is just a matter of selecting a package and every generation will feel that emacs is just what works for them. Just half (maybe quarter) tongue in cheek.

I'm not sure that's necessary.  It makes sense to have a set of well
thought-out defaults that work for everyone, or perhaps a few extra
custom themes (ie `gtk') that enable these options and are bundled with
Emacs by default.

I agree that Emacs is easier to program once you learned it, but
other editors, like VSCode, has the advantage that you don't have to
learn a quirky and unfamiliar language first.

Many developers know Javascript and even if one doesn't it's more similar
to mainstream languages than lisp, so extension writers mostly has to
learn the VSCode API only.

VScode has a very nice out of the box experience. If you want support
for a language then it's one click to install it and it installs the
necessary scaffolding too, like a language server for the language.

And it has Electron for display support which has a mature browser
engine behind it, so it can support advanced graphics features out
of the box on all the supported platforms.

Out of the box experience matters. Familiarity matters (e.g supporting
standard keys on the platfrom for cut and paste). Nice appearance matters.

No wonder lot of developers choose VScode:

Looks good. These are the changes Emacs needs, so it has a nicer first
impression for users who come from mainstream tools to give it a try.

Emacs shouldn't look old fashioned out of the box. It would be great
if it could use GTK widgets on all major GUI platforms, instead of
text buttons and stuff.

Here's the problem: You have to learn the VS Code API. I'd say learning
that, and becoming reasonably proficient at it takes longer than
skimming through the Emacs Lisp intro.

We have several starter packs, with similarly nice OOTB experiences.

Electron is not free software (https://labs.parabola.nu/issues/1167),
and is definitely not as well suited to providing an integrated
experience like Emacs.

For instance, even if you render raw HTML inside VS Code, you would not
be able to grab the region using VSC APIs.  I'm not sure if the VSC API
allows interacting with the DOM, but from what I can tell, it can't.

There are also various other issues, with relying on a lower-level
abstraction for "nice graphics features" (the DOM) that is outside the
editors control.

> Out of the box experience matters. Familiarity matters (e.g supporting

We have Cua mode.  No, you don't need to have it enabled by default,
since it would result in unnecessary breakage for old users.  It would
be nice if the startup screen informed users of features such as the
(hypothetical) GTK theme previously mentioned, and Cua.

I personally think that the Emacs bindings are better, and in the end
work better with Emacs itself, but I do agree that newcomers should be
allowed to familiarize themselves with Emacs before moving their
workflow (and habits) to it entirely.

I'd like to add that even though Electron might have some fancier
features, I don't consider it more "mature" than the Emacs display
engine, which has had a 25+ year head start to "mature".

IIRC, some important concepts in the display engine have existed since
the era of AI Lab Emacs, which gives the display engine a nearly 40 year
head-start.

Perhaps we could focus on adding missing features to Emacs' display
engine (such as the aformentioned fancy graphics, and also some other
important features that RMS has mentioned, such as variable-pitch
indentation).

Plus, if we implement those features manually, we can make sure that
they work consistently well throughout all the supported platforms.
(Which is also what you get with Electron, etc).

Agreed.  We could also add more GTK icons to x-gtk-stock-map as a temporary
measure for right now, since they are the icons that are used in X11/GTK
builds of Emacs, and my anecdotal experience tells me that's the version
of Emacs most beginners are likely to use.

In the long term, we really need to get rid of the legacy icons, many of
which are derived from the original X Window System distribution, and
are beginning to look highly out-of-date.

I don't think the general goal is for Emacs to imitate popular tools, but
instead to make it a mainstream tool.  To achieve this, we do need to
make Emacs more friendly for newcomers, but we shouldn't erase the
traits that make Emacs unique (such as extreme extensibility and
customizability).

IOW, everything added to make Emacs more friendly should be optional
(but easily discoverable), and should not break backwards-compatiblity with
existing configurations.

Emacs has endured for 40+ years. I doubt that without the Emacsen I
remember using with squeals of delight (Epoch, XEmacs, Emacs 19), and
the various improvements they curtailed that Emacs would still be where
it is now.  Let's help Emacs endure another 40 years.

Skimming the Emacs Lisp intro doesn’t make one reasonably proficient in
programming Emacs packages though. For one to understand how Emacs works
(with it’s obscure naming scheme like windows), one has to jump a lot of
hoops, and I can guarantee that one who is familiar with Algol-family
languages can pick up the VSCode API much faster than picking up Lisp,
Emacs, and the Emacs API.

But the default Emacs doesn’t have that, and that’s the problem.
Which means that, for one to have nice OOTB experiences, one has to have
a really good reason to use Emacs (like learning Common Lisp), then google
how to configure Emacs, then encounter Spacemacs without knowing anything
about evil or helm or ivy. And proficient Emacs users usually recommend
not using a starter kit in the internet. (That’s my experience on trying
to use Emacs.)

I don’t think OP was saying that we should use Electron for Emacs, but more
that due to using Electron, it gives the stability that Emacs doesn’t give.
Maybe you’ve only used Emacs on Linux, but at least on macOS, Emacs glitches,
locks, and crashes very frequently, and that’s a non-starter for a lot of  
people.

This is what gets interesting: Emacs Lisp is a language in it's own
right, and the "Emacs API" is the Emacs Lisp language.  Emacs Lisp is
also a rather small and simple language.

You don't have to pick up "Lisp", or the Emacs "API", you only
pick up Emacs Lisp.

We could put a link to them somewhere, but that's something for RMS to decide.

If it "glitches, crashes, locks", that's a bug, and instead of treating
it as a fact, report it.  Plus, I know a lot of people who use Emacs on
macOS, and I even had to use Emacs on Windows a long time back, and
Emacs has always been rather solid.  The starter packs are also supposed
to work well, and it might also be a problem with your own config.

OTOH, Lisp code shouldn't be able to make Emacs crash (unless you're
doing stuff like running invalid bytecode, or overflowing the GC stack),
and if it does, it's also a bug that should be fixed.

Learning lisp needs a new mindset while the VS Code API is just a bunch
of method calls.

And you don't need to learn the whole API. When I wrote an extension for
a test, to see how hard it is then I just googled things and used those
parts which I needed. I certanly didn't learn the whole vscode API, because
it wasn't necessary.

But they are not advertised on the emacs homepage, so a new user who just
googles emacs doesn't necessarily know about them.

I know it's not free software. I just meant it provided many features
out of the box which has to be implemented separately for emacs.

Certainly, it's more limited some ways, you don't have the freedom to
access everything like in Emacs.

Well, I think old users could adapt for the sake of new users. New users
shouldn't encounter lots of strange concepts from the start.

For example, the current tutorial may not be the best
approach. Explaining about cursor movement with C-f and C-b? Windows
and frames?

Why a new user who casually wants to try emacs has to start with this?

A new user can use the cursor keys and the mouse to operate the
menus. Rather than focusing on strange keys for cursor movement a
better approach could be explaining what emacs does better than other
tools and how to use those features.

And users could be informed on the startup screen that they can learn
traditional emacs keys in a separate tutorial if they are interested.

Exactly. Users should encounter a familiar environment first, using
the keys they are used to. They can always move on if they decide to
stay with emacs.

Re: Making Emacs more friendly to newcomers (was: "Why is emacs so square?")

[Eduardo Ochs]

There are several different ways of making Emacs more friendly for
newcomers, and we should take a look at all these different ways and
try to connect them somehow.

I gave a presentation about my way at the last EmacsConf. It's here:

  http://angg.twu.net/emacsconf2019.html

and I mentioned briefly in the presentation - in slides 11-13 - how
I've been using it to teach Emacs to lots of beginners. To make a long
story very short:

  0) install Emacs and eev in their machines,

  1) teach them the basics of Lisp _IN THE FIRST FIVE MINUTES_,

  2) show them how to navigate using the keys M-e, M-j, and M-k,
     and the menu bar and the tool bar.

From the docs:

  M-e   - to follow a hyperlink.  Mnemonic: "(e)valuate"/"(e)xecute".

  M-j   - to jump to certain predefined places. In particular, M-j
          without a numeric argument takes you to a buffer with basic
          help and a list of jump targets. See:

          http://angg.twu.net/eev-intros/find-eev-quick-intro.html#7.2

  M-k   - to go back.  Mnemonic: "(k)ill buffer".

Emacs Lisp as a language and the standard library (the Emacs API) is
different. For example, the fact that functions and variables have their
own namespaces is a part of the language, and the functions
self-insert-command or bury-buffer are parts of the API.

You can call them as a whole Emacs Lisp, but that doesn’t mean that
it’s more easier/simple than VSCode. Yes, Emacs Lisp isn’t a complex
language like C++, but for outsiders that have never used Lisp, it’s
hard to approach.

Regardless, Emacs can’t stop using Emacs Lisp, so Emacs needs to be the
reason for users to use Emacs Lisp, not backwards. And that means that
Emacs should have a great onboarding experience (which is currently not true)
with various packages for so many languages and productivity tools (which is
IMHO true considering all of the packages in GitHub).

Yes, it would be very useful if we can include some links to the starter  
kits.
Also, it would be great if Emacs can have a default init.el that gets  
generated
when there is no one, so that first time users don’t get a bad impression.

I know, I should report it, but I find that macOS/Windows is considered a

I wonder if icons in an obsolete gnome branch can be relicensed. It's GPL2
currently.

It has a standard GPL2 copying file in the tree and no more:

https://launchpad.net/gnome-icon-theme/+milestone/2.20.0

Does a standard GPL2 file implies later GPL versions too?

If not then they probably woudn't mind adding a README file saying "GPL2 and
later" the question is if they want to bother with this.

Do buffer-local variables count as part of the language, or part of the
API? What about text properties in strings? File-local variables?
Primitives like `record_unwind_protect_excursion`? Or how the bytecode
interpreter has a plethora of primitives that only make sense within
Emacs.

And I would consider `self-insert-command' part of Emacs Lisp the
language, since it is implemented as a subr in C code.

It's not hard to approach at all.  The easy trick is to treat it as an
editor macro language, instead of a Lisp dialect.

Emacs Lisp (more precisely, the first-class extensiblity) is one of the
main reasons to choose Emacs, and the onboarding experience is exactly
what we're talking about.

macOS/Windows are considered second-class platforms, when it comes to
features: features not available on free operating systems will not be
available on non-free systems.  macOS/Windows are not second-class
platforms, when it comes to fixing bugs not present on free operating
systems.

Your perspective is interesting.  However, I think new users should be
allowed to slowly adapt to the Emacs way, while being able to utilize their
existing workflow and habits, instead of being fed a new set of habits
and workflows in the first 5 minutes.

I was arguing that the surface area of Emacs is not smaller than VSCode,
which makes the exact classification unnecessary.

(FYI, I count buffer-local vars as a property of the runtime, text
properties are definitely an Emacs API, and `record_unwind_protect_excursion`
or other primitives, subrs like `self-insert-command` written in C are all
Emacs APIs. The language are things like if-expressions, macros, symbols,  
etc…)

I spread Emacs to my friends. Unless ones who already know Common Lisp,
almost everyone feels that Emacs Lisp is a big hoop.

First class extensibility is probably one of the big reason to use Emacs, but
that’s orthogonal to Emacs Lisp. And I can’t say that the onboarding  
experience
is really about Emacs Lisp - users don’t try to add keybindings or custom
functions on the first day of use.

Here's the problem: primitives like buffer-local variables, text
properties, and record_unwind_protect_excursion, and self-insert-command
all depend on Emacs concepts such as "buffers", "windows", "frames" and
on and on.  All of these are implemented as language primitives (and in
many cases, 'properties of the runtime', et cetera).  The Lisp
interpreter itself intermingles with "editor" code in a highly haphazard
and ad-hoc way, with many "APIs" being implemented as core language
constructs.

My view is: if the language still makes sense when X construct is
removed, X construct is considered outside the language.  If it doesn't,
X is part of the language.

You're not spreading it right, then :)
The Eintr teaches Emacs Lisp to non-programmers very well.  It also
teaches them how to extend the editor, in a straight-forward and
easy-to-understand way.

The reason Emacs extensiblity is so first-class is because functionality
for extending Emacs are implemented as primitives in the editor, and are
not "APIs" grafted on top of other languages, such as VS Code or
whatever.

Actually, the latest version linked from the Gnome wiki was not the latest version of
the 2.x branch.

It's this:

https://launchpad.net/gnome-icon-theme/main/2.91.93/+download/gnome-icon-theme-2.91.93.tar.gz

Released in 2011.

It has an updated COPYING saying:

"GNOME icon theme is distributed under the terms of either GNU LGPL v.3
or Creative Commons BY-SA 3.0 license."


So they should be asked to change it to "GNU LGPL v.3 and later" and then I guess Emacs
can use it.

I personally find that the stance of trying to not breaking anything is
one of the big reasons that Emacs has a nonusable-without-configuration UX.
Major version numbers are there for a reason… and we can expect for annoyed
people to set some variables to get old behavior.

Yes, these changes should be clearly marked in NEWS, so those who don't want
them, can revert them.

Out of the box Emacs should be instantly usable for newcomers and older users
could adapt for the sake of Emacs. I wouldn't mind adding a line to my .emacs to
turn something off which I don't need, but which can make the life of new
users easier.

For example, CUA mode could be on by default. I would turn it off, but it could
make the life of new users easier if they didn't have to turn it on explicitly
and they could use their copy/paste keys from the start like they are used it to
in other tools.

Major version numbers are there to announce new features.  With massive
changes (such as the ones that are being proposed here), you can't just
"flip a variable to get the old behaviour".  Especially people with 20
years of muscle memory and 200,000+ line configs.

Massive features that drastically change behaviour should be off by
default.  Stability over users. What's wrong with a button on the fancy
splash screen?

You can't turn massive changes off by adding "one line to my .emacs".
You can however turn them on by adding a button to the splash screen.

Emacs cannot and will never be usable out-of-the-box for 100% of all
usecases.  You can however make it easier for people to start, and again
that's when the "button on splash screen" approach comes in.

That mentality would lead to an unacceptable maintainence burden for a lot of
people.  Again: what's wrong with putting a button on the splash screen?

A button can work too. Or if emacs is started with no config file then it can
ask "Are you using Emacs for the first time?" If the user says yes then it
can offer to set some convenience features like CUA mode.

And if the user says no then everything is as usual.

The latter now occours to me as being the best solution.  Thanks for

No, people shouldn't need to learn a new language to use an editor.
In the ideal world, normal people should be able to use package.el and
custom.el to use Emacs without much fuss, and some people that is
interested in can develop packages.

It’s just that Emacs practically needs configuration to be usable - which
means that one must learn Emacs lisp.

Yes, Eintr teaches Emacs Lisp well, but that step should be optional.

They're implemented inside the language runtime, have relavant
primitives inside the bytecode engine, et cetera.  They're also the
primary (I wouldn't go as far as to say only, but it's close) IO
mechanism available in Emacs Lisp.

Indeed, normal people can do exactly that even today.  The point I'm
making here is that learning Emacs Lisp itself will let you extend
Emacs, and that there's no extra "Emacs API" to learn.

And it is optional; You can go by with package+custom fairly well.  I

I'm pretty sure neither "fancy graphics" inside file buffers, nor

What is the practical meaning of being "part of the program, Emacs" as
opposed to "being distinct from the program, Emacs"?  How does one
tell whether a given icon is in this or the other category?

E.g., we have a lot of icons in etc/images/.  We show these icons on
the tool bar and elsewhere when and where appropriate.  Are those
icons part of Emacs the program, or aren't they?

When did you last look at the tutorial that comes with Emacs?  We
mention the cursor keys there since Emacs 22.1.  We mention
PageUp/PageDown since Emacs 23.1.

We think using C-f/C-b etc. keys will help users type more
efficiently, and we say so in the tutorial, _after_ saying that the
"normal" cursor motion keys also work.  I see nothing wrong with that.

Re: Making Emacs more friendly to newcomers

[Sébastien Gendre]

# Re: Making Emacs more friendly to newcomers

Based on some suggestions on this topic, and some personal
reflections, I have a suggestion. (Sorry, I didn't read all messages,
maybe someone had already suggest the same thing)

Let's see some use-cases:
- Bob: A newcomer, who just discover Emacs. He search somthing who is
  visually modern, with all features he need to start writing code in
  most popular languages: Code colouration, auto-completion, code
  navigation, code documentation and functions/methods signature
  automatically shown, code errors/warnings signalling, REPL
  integration, snippets, strong GIT integration, etc. He also want to
  use basic features without the need to read a tutorial. Just install
  and go. But he is ok to read some tuto or manuals for advanced
  features. If we ask him question(s) about what to enable or not, he
  probably cannot respond (or thing he cannot). For him, Emacs need to
  be the most out of the box possible.
- Alice: A long time user. She got a personal Emacs configuration she
  had perfected over the years. She chose herself what system is used
  to show function completion, which code parser is used for her daily
  used languages. She add some packages to integrate with special
  tools used at her work. Emacs is her home and office: She use it as
  much for her personal project than for her work. She also made a
  personal workflow with org-mode and write some personal Elisp
  functions and advices. She forge the tools to her need. She do not
  want to have an update of Emacs who break her configuration, her
  workflow or her muscle memory.
- Mei: She simply want to use SpaceEmacs. She need to be sure
  SpaceEmacs would work out of the box and be able to override all
  defaults Emacs configuration. So SpaceEmacs developers need a way to
  doing their work without the need to deactivate a hundred of default
  features one after another and risk to forget one. This possibility
  should be well documented. As the need of Mei is covered by
  SpaceEmacs, she doesn't have special request about Emacs except make
  it easy to use SpaceEmacs.
- Roberto: He work on a pre-configuration of Emacs, similar to
  SpaceEmacs. He need a simple and documented way to deactivate all
  default configurations that would make is work difficult. If
  possible, in one move. And, of course, he need to know what is
  deactivated so he can choose wisely what to enable and what to not.
  
  
For these 4 use-cases, we can simply provide 2 flavors of Emacs:
- Emacs: With all the 2020 features, a modern interface, all needed
  modern features to start coding with most popular languages and easy
  to use for basic usages
- Emacs Vanilla: All the new features are still there, but deactivate
  to not break anything


And these 2 flavors can be in the same text editor: For switch from a
flavor to another, simply enable the global-minor-mode `vanilla-mode`.
And if Emacs detect, after an update or a first start, an already
existing configuration that it could break because of some features:
Emacs simply activate `vanilla-mode` automatically.


For our use-cases, this would be:
- Bob simply download and run Emacs. He got everything he wanted and
  start to code. Emacs can manage Bob projects, show documentation and
  errors, etc. Then, after some times, Bob can read some manuals to
  personalise his installation of Emacs.
- Alice update Emacs. When she restart it, Emacs detect an already
  existing configuration that it could break by enabling some
  features. So, Emacs simply enable `vanilla-mode` and add it to the
  `init.el`. Emacs also show a message to Alice: "Emacs detected that
  you have some personal configuration, so it active Vanilla-mode to
  avoid breaking your configuration. Vanilla-mode deactivate some
  features that you can re-enable manually.". This message is
  accompanied by a clickable link to the documentation about the
  `vanilla-mode` to see what it does in the details and what is
  deactivate.
- Mei simply download Emacs and SpaceEmacs. She follow SpaceEmacs
  instruction and everything work.
- Roberto add `(vanilla-mode)` to his `init.el` file and start writing
  his pre-configuration of Emacs. He is certain that no future version
  of Emacs would break his work and he can share publicly his
  configuration as SpaceEmacs or Doom Emacs do.

  
It's just a starting point, but I think this could be a simple but
very useful solution.

Well, for starters things like CUA mode, maybe a hypothetical `gtk'

You have a point.  We need to figure out why VSC is so popular, and then
fill in the areas that Emacs is missing.  A mostly out-of-the-box setup
probably counts in that area.

In both this and other messages, I get what you're saying and the goal
of making Emacs more accessible and more appealing is laudable and
ambitious, but definitely in the realm of possibility. (I think
/maybe/ some of the discussion is focused toward coding/software
development, and Emacs is much more than that, but I'll accept that
developers make up a big part of the actual and intended audience.)

But keep in mind that I'm old and grumpy and have used Emacs for
literally decades. When I started on Emacs back in the 80s, I knew
nothing. All I had used up to that point was a series of line-oriented
editors similar to 'ed'. Now (the question of graphics put aside in
that pre-graphics era), how did I learn Emacs? I went through the
tutorial carefully and fully. By the end of that I was a fledgling
Emacs user. It was enough for me to be able to do actual work.

Then, as I needed new things, I learned them. There was no internet so
I relied upon the Emacs manuals, which were and are very good
references. I picked up elisp as necessary. And it all worked out. Did
I jump right in and use Emacs out of the box? No. I knew I was making
a long-term investment in doing the tutorial, etc.

So here's the grumpy old man part: I sometimes think that today,
software is expected to fall into the instant gratification category.
A lot of users don't want to have to learn anything, they just want a
perfect out of the box experience. But I think those are conflicting
expectations.

Yes, make Emacs appealing and user friendly. But don't forget that a
masterful tool in the end requires mastery, which can't come for free.
I certainly draw the line at saying Emacs is for everyone. I'm not
saying it's only for some sort of snooty "elite" but I am saying that
it's for those who are willing to learn, seeing some extra work as the
aforementioned long-term investment, and who have the patience reach a
worthy goal a little later rather than right this very minute.

I'm personally not against the idea of having a separate backwards
compatibility mode.

But I guess we would need to pull in several third-party packages to
have a modern "batteries included" Emacs.  AFAIK, that is
unfortunately not possible given the copyright assignment requirement.
But perhaps a default "modern" mode could be a bit less ambitious.

It is a legal question.  If a file of code is under the GPL, the
GPL applies to the entire program or work that the file is part of.

But it does not apply to other, separate works that are distributed
WITH that program or work.  Separate in regard to copyright law, I
mean.

I don't know a simple way to describe this, sorry.

I think it depends on how things work to display those images.
And I don't remember that.

When Emacs wants to display etc/images/attach.pbm, how does that work?
Does attach.pbm get somehow linked into Emacs?  Or does Emacs open
etc/images/attach.pbm at run time, read it, and display it?

With the first method, they are part of one combined work.

With the second method, it is valid to say they are two separate works
and treat them as such.

At least, such is the understanding I got from lawyers around 30 years ago.

With two _programs_, the issue is different.

That statement may be correct, but you've changed the topic.

You're talking specifically about VS Code, which is a "source code
editor".  What I had in mind, regarding variable-pitch text, was word
processing.

Those are not part of the Lisp language, so they are not really
part of the mission of the Lisp Reference Manual.
It does document some internal C conventions because they are useful
for people who want to customize at the C level, but we do that
only to the extent that seems worth doing.

Did I?

The topic was Emacs's popularity, AFAICT.

It's already a good source code editor, and yet its share among 
programmers is < 5%.

As a word processor, it's a lot less capable, and adding the two 
features you mentioned above won't bring us much closer to that goal, 
compared to established options. And there are existing Free programs 
that do this better already (like LibreOffice Writer).

We certainly should enable all kinds of uses, but given the limited 
resources, I think we should play to our strengths first.

How will any of this differ from the many existing canned default setups
already available? In fact, given the limitation on only using Emacs
built-in packages, is it even possible to do a setup which is even close to
some of these canned setups, many of which appear to be targeted at new
users (spacemacs, doom, prelude, etc). Are we just talking about a GNU
canned configuration?

I'm also old and grumpy, and I pretty much learned Emacs the same
way (and only about a decade after you did).
It would still be nice if we had a way for making Emacs easier for
today's lazy people to learn though.

I mostly agree, but the problem is a lot of people aren't willing to
make said investment due to prior prejudice, and you need a way to clear
that prejudice up.

I was referring to how such features would allow people to potentially
create nicer (well, mostly) graphical interfaces inside Emacs, which
would in turn make Emacs appeal more in the minds of those who judge a
book by its cover.

Word processing in Emacs would also be nice.

I'm afraid it's not that simple.  I don't think we need any radical
changes in Emacs to be turned on by default, but maybe something like a
set-up wizard or "New to Emacs? Click here" would be useful.

I'm not sure whether Emacs can reliably detect updates or not.  IIRC,
there was a discussion a while back that said no.  Plus, as I've
previously mentioned, I don't think Emacs should adopt any drastic
changes as the default configuration, but instead make the changes
easily discoverable.  (or at least until all of us old farts have had
another decade or 2 to adjust).

You are right, there is LibreOffice, and I don't need Emacs to be
another WYSIWYG word processor.

But that said, it's already a terrific text processor, especially with
org-mode. I've written 8 novels in English, 1 in French, and countless
short stories with Emacs. I couldn't conceive of a more productive
writing tool, and in the writing community I know of many others who
feel the same way.

The AucTeX interface to LaTeX makes publishing feasible, too, although
I admit that's yet another learning curve to traverse.

It is not that they are lazy, just like people who use a machine to do their laundry instead of doing it by hand, they use tools that have been developed without the historical constraints of Emacs.

I can’t understand why you’re so opposed to changing defaults. Defaults
matter, and I think that users who are already accustomed to Emacs will
have an easier time changing options. (Like adding `(vanilla-mode 1)`
to init.el.)

Defaults have to change for experienced users to adjust. And for them,
adjusting is an easy task, not something that takes a decade.

I oppose changing defaults, because I value my tools remaining stable.
Having to frequently adjust my user-emacs-directory to encompass the
latest fancy new idea is an unacceptable maintenance burden to me.  Not
to mention in practice, those changes are going to be far larger than a
hypothetical `vanilla-mode'.

I'm not sure what you're talking about; Variables don't persist across
Emacs sessions.

> The features that are best discoverable are the ones that are default.

And since changing the defaults radically end up hurting existing users,
and also existing packages and potentially the existing ecosystem.  You
have to find a balance between that, and changing the defaults is not
the balance you want.

"For existing users to adjust" is not an excuse -- that puts an extra

Agreed, but I believe most package maintainers would be willing to
assign copyright to the FSF.  (For instance Eglot would count as an
important package, and it's in ELPA).

Then you can turn on ‘vanilla-mode’ on your init.el and call it a day.
‘vanilla-mode’ will be the current situation of Emacs - it will try to
be stable.

Why? If you’re fine with the current level of changes in Emacs, that would
be the level of changes in ‘vanilla-mode’.

I’m saying that one can add a variable like ‘expected-emacs-version’ and
when Emacs is loading init.el and ‘expected-emacs-version’ is different
from the current version, Emacs can warn you.

No, it doesn’t. Better defaults help users and allow them to lighten their
configuration.

The balance I’m suggesting (actually ndame) is to add a ‘vanilla-mode’ for
people who value stability over features.

Not thus far. Does VS Code do that?

Sounds like a good cause for a feature request. And if such an install

Sure. And I've heard similar reports myself. But that's a more

Re: Making Emacs more friendly to newcomers

[Stefan Monnier]

For the record, I have a proof-of-concept package for GNU ELPA which
I call `gnu-elpa` and which just adds "most" of the autoloads found in
GNU ELPA packages (along with the corresponding changes to
`auto-mode-alist`), such that `M-x eglot` or opening a smalltalk file
will prompt the user if they want to install the corresponding package.

It's not as good as activating `eglot` and `company`, but I think such
a `gnu-elpa` package should ideally be bundled with Emacs-28.

There's a flaw in this description of how long-time Emacs users
concoct their configurations.  What's in their configuration depends
_heavily_ on the defaults: the features whose defaults satisfy such
users are never touched in the init file.  Any "vanilla" Emacs that
turns off many features will run a high risk of breaking such
configurations, because it violates the assumptions on which those
configurations rely.

At least, that's how I maintain my init files.

The first and the most important problem with this is to identify what
you informally call "all the 2020 features, a modern interface, all
needed modern features to start coding with most popular languages and
easy to use for basic usages".  If you review past discussions on this
and related subjects, you will see that opinions on what should be
part of that set of features vary widely, so much so that I don't
believe any significant agreement is practical.  It _might_ be
possible to come up with a relatively short list of features that
could "modernize" Emacs, about which enough people will agree that
they should be part of "2020 features".  However, I'm not sure even
this limited goal is possible, and will continue to be unsure unless
and until someone comes up with such a list, and we see what's in it
and how many people agree on the list.

On top of that, the list (and the dispute to go with it) will need to
be updated with each major release.

Suppose we do have such a list -- will that be enough to make Emacs
sufficiently more attractive to Bob and his friends?  I don't know.
One problem is that we don't have many such Bob's on our team or even
reading this list, and those few who are very quickly become Alice's.
So their voice is never heard.  We don't have any HFE experts on
board, who could pretend to be a Bob.  So who will be able to
represent them and make sure the list of said features will be to
their liking?

> - Emacs Vanilla: All the new features are still there, but deactivate
>   to not break anything

I'm guessing that by "new" you mean all those "modern" features that
we don't currently turn on by default.  Otherwise, I don't see any
useful purpose for such a "vanilla" Emacs.

I don't see how Emacs can do that, when many dozens of optional
features are involved.  How do you write code that detects whether a
given feature can break something?  Ideally, we will have already
considered that, and make every effort not to break any existing
feature or muscle memory.  And who will write and maintain such code,
and update it with each release?  Are you aware of any other project
that does anything similar?

> It's just a starting point, but I think this could be a simple but
> very useful solution.

This assumes that someone does all the research and design and
implementation needed for that, and that we as a project commit to
maintaining these very non-trivial facilities for the years to come.
You may not realize it, but this is a very far cry from what we do
now.  For example, it is a long and frustrating uphill battle just to
make sure that NEWS provides information for how to get back old
behavior, for every one of those new features that do change behavior.
Please try to imagine (and describe to us, if possible) what kind of
development procedures will have to be put in place to support what
you propose, which is much more complex and problematic.

It's the latter.  More accurately, we look up the file in the
filesystem, then pass the full file name to an image library which we
link with Emacs, and that library reads it.  And many icon files come
with every Emacs tarball and in any binary distribution, of course.

So since this is the second method, what are the legal requirements
from icon files that we bundle with Emacs?  Just a free license?  And
if so, what kind of license?  Are there any other requirements?

Thanks.

It's not that simple.  Some features that are turned on cannot be
easily turned off afterwards.

Experience shows that you are in disagreement with a large bulk of our
users.  They tend to complain loudly when they bump into some changes
of defaults that they dislike, or find that behavior they were
accustomed to changed too radically.

As Eli said, Electron is covered by an MIT license. It describes itself
with this sentence:

  Build cross-platform desktop apps with JavaScript, HTML, and CSS.

It accomplishes this by uses Node.js, a JavaScript runtime built on the V8
javascript engine of Chrome. Each Electron app comes with its own
integrated copy of Chromium (the "free" parts of Google's Chrome web
browser, released under a combination of 3-clause BSD, MIT, [L]GPL, and
MS's Shared Source licenses). Without intensional malice, I'd call it a
Frankenstein's monster of both code and license.

Its major features are (in my personal opinion): Google invests effort into
making it function well across major platforms, it's "free enough" that it
can be used by various open, free, and commercial projects, and it lets
people make "desktop apps" using the widely-known web stack of JavaScript,
HTML, and CSS. It can use native code via Node's analog of an FFI. This
combination is so widely spread and optimized at this point that it's
possible to get decent performance alongside gui, threaded, network, etc.
code. It also has a reputation for being fairly bloated, in large part
because each Electron app brings its own copy of chromium, V8, node, etc.
Similarly, Electron apps are rarely well-integrated into a particular OS,
since they're mostly WWW technology; whether this bothers users or not is
currently a shifting topic, as ever more new users are used to using
web-based tech for much of their computer needs.

I hope that helps,

The Emacs Lisp Reference Manual documents the use of buffers

A long journey has to be achieved step by step.  Since 1990 I have

I use LibreOffice.  It works, but I very much miss the 
fundamental capabilities of Emacs.

I want to do word processing in Emacs and program commands in Emacs Lisp.

What do you mean?  I haven't seen the default binding for `C-v` changed

That assumes the person with the config puts that variable in, and
anyway it makes for more maintenance burden.

There is no "better default".  There's only the default that remains

You can't stuff major changes in a `vanilla-mode'.

I wasn't referring to how buffers can be operated from C code.  I was
referring to how buffers are an integral part of the Emacs Lisp
*language*, and not some hypothetical "standard library".

I was also referring to how the Eintr explains how buffers can be
manipulated from Lisp code quite well.

Please keep in mind that if we hope to make Emacs reach, say, 30% share 
among programmers, the extra 25% would be new users.

So for all questions about changing defaults, we should ask ourselves, 
do we prioritize the existing 5% (or 3%, as SO poll says) userbase that 
will naturally continue shrinking over the years, or whether we prefer 
to make life easier and more productive for the users that should come 
later.

And it's not like existing, long-time users can't grow to like the new 
defaults (even after a certain amount of grumbling). I think the Xref 
example shows that.

I checked the KDE icons too and they have this text for license (excerpts):

    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 3 of the License, or (at your option) any later version.


Clarification:

  The GNU Lesser General Public License or LGPL is written for
  software libraries in the first place. We expressly want the LGPL to
  be valid for this artwork library too.

  KDE Oxygen theme icons is a special kind of software library, it is an
  artwork library, it's elements can be used in a Graphical User Interface, or
  GUI.




It contains the later version clause too for LGPL, so I guess the problem
of icons is solved.


There is a choice too, both of these have this license. Emacs could even
offer a choice of icon themes for the user:

Lots of people are writing books and articles in Emacs using Org 
mode, which is as close to a full-blown office suite (word 
processor, PIM, spread sheet, presentation editor) as any text 
editor will get. If you want to do word processing in Emacs, you 
should check it out and see where it can be improved/extended to 
get to where you want Emacs to go.

Yes.  AFAICT their primary method for language support is the LSP

have an extension "marketplace" (closest anology here would be ELPA)
that has a nice way to install various language servers.

`lsp-mode' also has similar functionality.  It would be nice to have it

That's interesting.  I remember someone working on something similar,
but would find autoloads inside any package.el repository (it would
download, extract and cache the autoloads from a list of packages
beforehand).

Yeah, that would be nice.

Re: Making Emacs more friendly to newcomers

[Sébastien Gendre]

Having a Vanilla-mode are maybe wore difficult than it seems.

So, let's forget Vanilla-mode and see another solution who can be more
feasible.

Maybe we can take inspiration from the work of Spacemacs and Doom
Emacs: Offer an official pre-configuration of Emacs, on the side of
Emacs itself. This pre-configuration will be more focused on new users
and
new features when Emacs itself would be more focused on stability.

Here is, in more detail, what I have in mind.

On one side, continue to develop Emacs as today :
- Keep same defaults
- If a new features is proposed, check if it break any compatibility
  or defaults
- If no, include it in Emacs
- If yes, try to modify this feature to not break any compatibility or
  defaults and if its a success, include this feature in Emacs
- If it's not possible, include the feature but deactivate it by
  default or make a package on ELPA
  
  
I don't think this side is different from what development on Emacs is
today. We can call this side Emacs vanilla, or Emacs core, or Emacs
base. Anything that reflect that this is the common base for everyone.


On another side, we can create a pre-configuration (like what
Spacemacs or Doom Emacs do) :
- All this pre-configuration is a set of files to be put inside the
  .emacs.d to start using it (like Spacemacs)
- Main goal is to have a pre-configuration that provide what is
  commonly expected from a modern text editor [1], out of the box
- Easy to use for the common tasks
- Enable some features that are not enabled by default
- Modify some defaults behaviours of Emacs to reflect more what new
  users search in a text editor
- Can include some packages from ELPA (if no legal or licence issue)
- This pre-configuration can be done by a dedicated team who
  collaborate with who work directly on Emacs
- The structure of this pre-configuration need to be made to not
  conflict with user personal configuration (ex: avoid to put anything
  in the init.el, use separate sub-directory inside .emacs.d, etc)
  
  
The actual Emacs show that the first side is possible. And projects
like Spacemacs and Doom Emacs show that the second side is also
possible. So I think this solution is feasible. And a direct
collaboration of the both side can make the process more easy.

A remaining problem is: How provide the pre-configuration easily and
out of the box for new users, without breaking long time Emacs users
configuration?

A possibility would be:
- When Emacs start, it check if a configuration already exist on the
  user directory (~/.emacs.d or ~/.emacs)
- If yes, Emacs start
- If no, Emacs restore the pre-configuration inside ~/.emacs.d then
  start

With this, new user can use the "modern, shiny, OOTB Emacs", out of
the box, by simply download and run it. And the long time user can
have a stable Emacs who don't break their configuration. For someone
who want to use Spacemacs, simply extract it as ~/.emacs.d before
start Emacs. And for someone who want to start Emacs without a
pre-configuration, simply create an empty directory for ~/.emacs.d.

Of course, the pre-configuration can be updated automatically with
Emacs. As the files of this pre-configuration are separated from user
specific configuration.

Open questions remain:
- Does the pre-configuration release cycle are synchronised with Emacs
or
  completely independent?
- Does the user can block the pre-configuration update, to avoid
  breaking its configuration based on a specific version of the
  pre-configuration?

But I think this can be a realisable solution. 

[1] List of features to be defined, but I imagine some out of the box
auto-completion, code navigation, functions documentation + functions
signatures + errors showing automatically, strong integration with git
(Magit?) and debuger, major containers engines (docker, kubernetes)
integration, etc. With a great support of the most populare
programming languages. And maybe have a special attention to integrate
with web technologies and tools for web developer.



PS: Or maybe we think to much about this problem. And making an LTS
versions of Emacs, like Ubuntu does, is the solution.

And then, another 20 years pass, the current users get too old/change 
careers/retire/etc, and Emacs's userbase shrinks even more.

I don't want Emacs to die out, and it will if we don't do the work of 
attracting new users.

Also note that we don't really have the ability to poll even our 
existing users, to find out whether they would like a given change. Even 
disregarding those who would change their mind later.

Give it time.

I didn't talk about that, but...

I think it's possible to support two sets of keybindings. That's 
definitely extra work, though.

Including simply designing a set of bindings that is both compatible 
with CUA and yet retains the current design principles to some extent 
(so far I have no good ideas on that front).

As was already said in this thread, the main problem with this is to
come up with the list of features to turn on.  Did you ask yourself
why there's Spacemacs and Doom Emacs (and a few more variants), and
not just one?  It tells us something about the commonality of
preferences.

Does this mean users who download this "shiny Emacs" will be unable to
upgrade to a newer version?

So you propose to have config files that users shall never touch?  How
likely is this going to hold, what with Emacs users being very
inquisitive folks?

This is the main problem to solve, so its place is hardly in the
footnotes ;-)

I like the idea. If I open a Racket file in VSCode, it show a prompt that asks me if I want to search the “market place” for a racket plugin. If I click yes and click install, everything magically works. Now my racket buffer has completion, highlight, etc. For more popular languages like python, VSCode even auto detects for linters and python executables, etc. And with one click it finds (or downloads) linters and executables and sets them up for me. Maybe it is hard to make Emacs as pretty as VSCode (with all the fancy visual web tech); but making Emacs smarter and more helpful should be a tractable task. We already have Customize, all we need to do next is to add some smart helper functions that install packages and setup stuff.

I have a suggestion that might circumvent this whole discussion.

Just now, I turned on the toolbar and entered bug reporting mode with 
'M-x report-emacs-bug'. I am using a GNOME theme specially made for Ubuntu.

The attached picture shows a toolbar with an assortment of icons where 
about half obey the current theme and the rest don't. I also tried 
switching between icons themes to confirm this.

The icons to the left of "Send Message", as well as the "Kill Message" 
icon, change together with the themes. The red round thingy with an "x" 
changes only with some themes, but not with the rest. Perhaps that means 
that the icon with that name/identifier is themed more rarely. But it's 
still somewhat standard.

The rest of the icons ("Send Message", "Attach File" and the rest after 
it) never follow the theme.

Perhaps the solution, at least for the GTK builds, would be to find the 
standard icons (more concretely, icon names) that can be used for these 
buttons, instead of picking among the icon sets. The latter should be 
the user's choice, after all.

The pre-configuration could contain just one line:

   (require 'shiny-settings)

where shiny-settings.el is distributed with Emacs and is updated 
together with new releases.

Although, after 5-10 years pass, we'll surely encounter users of 
previous versions unhappy with changes to their shiny-settings too. :-)

  > Also note that we don't really have the ability to poll even our

We have done it many times.  Here's the method I developed for polls
in the past:

* Make a file for the replies to go into.

* Make a mailing address which drops all mail into the file.

* Mail to info-gnu-emacs and help-gnu-emacs, and any other suitable
place, presenting the proposed change in sufficient detail that people
can judge it, and where to email the response, as well as what kind of
information we seek.

What we seek is not "votes", but understanding.  If you are for the
change, please explain why.  Would it help you directly?  If so, in
what scenario, and what would the benefit be?  And how important?

Or is it that you think it will help Emacs development by helping
others?  Please distinguish between what you know and what you guess.

Likewise, if you are against the change, please explain why.  Would it
inconvenience you directly?  If so, in what scenario, and what would
the inconvenience be?  And how important?

Or is it that you think it will harm Emacs development by
inconveniencing others?

We invite you also to propose changes in the proposal that would
improve it, for you -- saying in what scenario, and how.

* We state a deadline some weeks in the future, but since there is no
hurry, we wait some extra time before we look at the responses.

* Ultimately, we do not restrict ourselves to choosing between "make
the change" and "don't make it".  The best outcome is that the
feedback enables us to design a way to please almost everyone.

It is ok to do this with GNU ELPA,
because we could move those packages into the Emacs distribution
if that ever seems advantageous for any reason.
We don't have an essential need to make a distinction between
the packages in GNU ELPA and the ones in the Emacs distinction itself.

I found it impossible to learn what Org mode does.  Its introduction
taught how to do outline editing.  It made sense, but outline editing
useful for me, so I stopped reading.  I did not want to study use of a
mode for outline editing.

When you tell me that Emacs has important facilities -- doing jobs
very different from outline editing -- that I don't know about because
they have been integrated as "part of Org mode", my conclusion is that
we should have integrated them differently.  Those other facilities
should not be treated as "part of Org mode".  They should be separate
facilities, each one documented separately, and usable by itself.

I would like to see those facilities separated from Org mode and made
into separate first-class subsystems.  Then they can be documented in
the Emacs manual.

That is a free license, compatible with GPL 3, and will be compatible
with future GPL versions as well.

We've determined that the icons are separate works from Emacs.  So
we do not need their licenses to be compatible with any GPL versions.
We just need them to carry a reasonable free license.

This is entirely logical

I don't think the concept of "standard library" makes sense for Emacs
Lisp.  However, I conceptually divide the programming facilities
of Emacs into 

* The Emacs Lisp language

and

* the editing facilities.

I see buffers as part of the editing facilities, not part of the Emacs

Nitpick: `require` is *really* not the right job since just loading
a file should not change Emacs's behavior substantially.

Ideally, it should be a custom-theme, but second best could be
a minor-mode.

I'd say Emacs can be made to look just as nice as VS Code with some
minor tweaks, and yeah it would be nice if Stefan's package (or
something similar) would be able to suggest Geiser upon opening a Scheme
(or Racket) file.

I'm not sure I see that distinction, since Emacs Lisp as a language
doesn't really make sense without the editing facilities.  It would make
sense to classify Emacs Lisp as a whole as a highly domain-centric Lisp dialect.

I have seen people say Emacs will die by 2000 in the 90s.
I've also seen people say Emacs will die by 2010 in the 2000s.
I've also seen people say Emacs will die by 2020 in the 2010s.

Since all of those predictions of doom have consistently failed, I'm not
inclined to believe any of this either.

And we're attracting a fair amount of new users.  What I would hate to
see is Emacs prioritizing "attracting users" over "being useful".  I'm
sure many in the community agree with me.

The anecdotal experience of many people I know (and I'm sure many people
on this list too) would agree that drastic changes are a bad thing.

Also, Xref was actually useful in a way.  Drastic redesigning just to

We already have Cua Mode.  Having a button on the splash screen that

Indeed! Emacs is the only editor that I grew to like. Other editors and

There may be a misconception about what Org really is. It is unfortunate
if its documentation lets one think the mode is about outline editing.

  Org is both a lightweight markup language, and a major mode to edit
  it. Versatile, it is useful for keeping notes, maintaining TODO lists,
  and project planning. Powerful, it may be used as a complete authoring
  system, with support for literate programming and reproducible
  research.

Outline editing is but the design choice that was made for the major
mode to edit documents with Org syntax. To put it differently, the
common factor between the "other facilities" you mention, whatever they
are, is not the outliner part, but the markup language behind it.

As a consequence, it probably makes little sense to separate such
"facilities"---the term would need to be properly defined in the current
context, tho---, because each of them implies full support for the whole
Org syntax.

As a side node, there are attempts to proceed the other way. For example
OrgTbl minor mode, included in Org for historical reasons, edits---a
subset of---Org tables in other major modes. Likewise, Orgalist, found
in GNU ELPA, ports---a subset of---Org lists to other major modes. None
of them equates its native counterpart for the reasons explained above.

Conversely, I'm thinking out loud here, there is one external facility
that I would like to see integrated into Emacs proper, so major modes,
such as Org, could use it. It is Citeproc.el, a library for rendering
citations and bibliographies in styles described in the Citation Style
Language (CSL).

Given that I've had multiple *useful* proposal about changing defaults

I don't think I follow.  Where can I find this "GNOME theme"?  It's
not part of the Emacs release tarball, is it?

What exactly do you mean by "icons follow the theme"? how does a theme

AFAIR, last time we made such an effort, we indeed took icons from GTK
or GNOME or from some similar collection.  But that was a long time
ago, and in particular the two rightmost icons you see in Message mode
were not part of that set, they were added by someone later.

So we expect users not to customize their Emacs, as long as they use

It's shipped by GNU/Linux distributions, typically.

In GTK builds (the default in Debian, and probably others), the toolbar uses icons from the current GTK icon theme.  I believe this is done in update_frame_tool_bar in gtkutil.c.

It should be enough to change the name of the icons on the toolbar. No need to take icons from GTK (if that means copying files into the Emacs repo).

IMNSHO, the Org manual "needs work"™.  Its current form shows the long
history of the package, more than it shows what it is nowadays.  I
mean, consider this opening phrases in Introduction:

  Org is a mode for keeping notes, maintaining TODO lists, and project
  planning with a fast and effective plain-text markup language.  It also
  is an authoring system with unique support for literate programming and
  reproducible research.

     Org is implemented on top of Outline mode, which makes it possible to
  keep the content of large files well structured.  Visibility cycling and
  structure editing help to work with the tree.  Tables are easily created
  with a built-in table editor.  Plain text URL-like links connect to
  websites, emails, Usenet messages, BBDB entries, and any files related
  to the projects.

     Org develops organizational tasks around notes files that contain
  lists or information about projects as plain text.  Project planning and
  task management make use of metadata which is part of an outline node.
  Based on this data, specific entries can be extracted in queries and
  create dynamic _agenda views_ that also integrate the Emacs calendar and
  diary.  Org can be used to implement many different project planning
  schemes, such as David Allen’s GTD system.

Etc., etc.  I invite you to put yourself in the shows of a newcomer to
Org, and try to imagine how such a newcomer will be able to realize
that Org can be used as a word-processor...

So please don't be surprised that Richard thinks about this what he
thinks.

Now, suppose someone tells me that Org includes word-processing
capabilities, and I'm excited about that and want to learn how to do
that.  Here's the menu I'm presented with in the Top node:

  * Introduction::                 Getting started.
  * Document Structure::           A tree works like your brain.
  * Tables::                       Pure magic for quick formatting.
  * Hyperlinks::                   Notes in context.
  * TODO Items::                   Every tree branch can be a TODO item.
  * Tags::                         Tagging headlines and matching sets of tags.
  * Properties and Columns::       Storing information about an entry.
  * Dates and Times::              Making items useful for planning.
  * Refiling and Archiving::       Moving and copying information with ease.
  * Capture and Attachments::      Dealing with external data.
  * Agenda Views::                 Collecting information into views.
  * Markup for Rich Contents::     Compose beautiful documents.
  * Exporting::                    Sharing and publishing notes.
  * Publishing::                   Create a web site of linked Org files.
  * Working with Source Code::     Export, evaluate, and tangle code blocks.
  * Miscellaneous::                All the rest which did not fit elsewhere.
  * Hacking::                      How to hack your way around.
  * History and Acknowledgments::  How Org came into being.
  * GNU Free Documentation License:: The license for this documentation.
  * Main Index::                   An index of Org’s concepts and features.
  * Key Index::                    Key bindings and where they are described.
  * Command and Function Index::   Command names and some internal functions.
  * Variable Index::               Variables mentioned in the manual.

Hmm... which one of the chapters should I read?  I tried "Publishing"
first, but quickly realized that's not it.  Next, I tried "Exporting"
("Sharing and publishing notes.", right?) -- another false hit.
Finally, I thought maybe it's in "Markup for Rich Contents".  This
time I think I found what I was looking for, but look at that
chapter's menu:

  * Paragraphs::                   The basic unit of text.
  * Emphasis and Monospace::      Bold, italic, etc.
  * Subscripts and Superscripts:: Simple syntax for raising/lowering text.
  * Special Symbols::              Greek letters and other symbols.
  * Embedded LaTeX::               LaTeX can be freely used inside Org documents.
  * Literal Examples::             Source code examples with special formatting.
  * Images::                       Display an image.
  * Captions::                     Describe tables, images...
  * Horizontal Rules::             Make a line.
  * Creating Footnotes::           Edit and read footnotes.

This sounds like a more-or-less random collection of related tidbits,
not an explanation of how to use Org as a word-processor.  And as soon
as I go to the first section, "Paragraphs", I'm almost immediately
lost:

  Paragraphs are separated by at least one empty line.  If you need to
  enforce a line break within a paragraph, use ‘\\’ at the end of a line.

     To preserve the line breaks, indentation and blank lines in a region,
  but otherwise use normal formatting, you can use this construct, which
  can also be used to format poetry.

       #+BEGIN_VERSE
	Great clouds overhead
	Tiny black birds rise and fall
	Snow covers Emacs

	   ---AlexSchroeder
       #+END_VERSE

What are those "#+BEGIN_VERSE" and "#+END_VERSE" markers?  Do I type
them verbatim in the text of a document?  There's no answer.  (Of
course, yours truly is somewhat familiar with Org, so _I_ know the
answer.  But a newbie won't.)

This is not what a chapter about using a word processor should look
like.  It should begin with an introduction to word-processing with
Org, an overview of what's possible and what isn't; it should go on to
explaining how to start a document, how to write a heading and a
sub-heading, how to insert references, links, footnotes, and other
objects; it should then explain how to produce a TOC and an index, and
finally point me to another chapter that explains how to export my
document in a variety of formats.

A good example of how such documentation should be structured is at
the beginning of the Texinfo manual, which also describes a system for
writing documents.  Look at the first dozen of chapters there for
inspiration.

Maybe you took the "separate" part to mean that the _code_ should be
separated or subdivided.  I'm not sure Richard meant that, but even if
he did, what I would like to see is a "separation" on the
documentation level.  Let a user who only wants to write documents
with Org be able to learn that without reading 50% of the Org manual,
in order to understand "the whole Org syntax".  Allow a user who is
only interested in GTD to be able to do just that by learning the
necessary Org commands and procedures, and little else.  Etc. etc. --
try to "separate" what Org is capable of into several large classes of
jobs, and make sure each of these classes is documented clearly and
logically, as if it were a separate manual (and maybe it really should
be a separate manual, I don't know).

I hope I explained at least what is my view of how Org should evolve
(in addition to the routine development that adds new features) -- it
should try to present a less monolith-like appearance towards new
users, and allow them to master just a part of its capabilities, the
part that they are interested in.

Then I don't understand the complaint.  The icons that don't change
are our private icons that aren't taken from GTK.  So how can they
"follow the theme", if they are absent there?

That would only help GTK users.  I thought we wanted to improve the
Emacs appearance on more than just one toolkit, especially since that
toolkit is troubled and many users avoid building with it for that
reason.

Yes, of course. Here is the theme used on my machine, for example: https://github.com/linuxmint/mint-y-icons
strace-ing `emacs -Q' on my machine suggests that it loads the following icons for the default tool-bar:

  13718:openat(AT_FDCWD, "/usr/share/icons/Mint-Y/actions/22/document-new.svg", O_RDONLY) = 15

IIUC, the claim is that there (likely) are standard icons close to the ones we use, and that using the corresponding icon names would give us good-looking icons by default on Gtk.
Concretely, for the actions shown in the message toolbar, this would be these:

mail-attachment 
document-send or mail-send
tools-check-spelling
mail-mark-important

The spec doesn't seem to have actions for marking an email unimportant or requesting an email receipt.

Sure, importing icons is also a good idea.  But the OP was making the point that we can easily improve the situation without bikeshedding a specific icon choice by respecting existing user themes.

Yes, indeed. But it's still probably the most popular toolkit among 
GNU/Linux users.

On e.g. Lucid all icons come from the same set, at least. We can improve 
them as well (all together), but it's a fairly different task.

Speaking of other platforms, I wonder if Windows and macOS also have 
have standard sets of icons.

It would make our task easier (and the end result more native-looking) 
if we could use a similar approach.

Making a proper GTK backend will not remove the reason that people
build with lucid, which is wanting emacs to be able to survive X
disconnects, unless we have evidence that proper GTK works in that
scenario.

It will help with things like HiDPI autoscaling, and maybe frame
resizing.

Someone in this thread mentioned they were working on a 'proper' GTK
backend, is that anywhere near useable yet?

And the icons look the same, no matter what distribution are we
talking about?  Doesn't something depend also on the desktop that's in
use, and perhaps also on the window manager?

"Standard" as in "subject to change without notice" each time the
vendor decides to change the look-and-feel (which happens roughly
every 2 to 3 years).  And that's even before we solve the problem of
showing those "standard" icons in Emacs -- e.g., on Windows it is
customary to compile the icons into the binary, something that we
cannot do and then distribute the binary from the GNU FTP site.

I'm not sure I like this direction.  It sounds like the opposite of
having an Emacs that looks more or less the same on all major
platforms.  How will the users (and newbies at that, since we are
talking about them primarily) be able to find their ways in Emacs, if
the icons change with the desktop/platform, and every few years even
on the same platform?  E.g., you buy the Emacs manual printed a year
or 2 ago, but the icons it shows are all different from what's on
display.  I don't even understand how will we be able to show the
icons in our Info manual, if the images don't come with Emacs and are
different on each platform/build.  Do we really want to go in that
direction? just to say we look "modern"?  Something people should
seriously think and make up their minds about before such decisions
are made, I guess.

Because of how it evolved, there is clear separation.
And it's hard to retro-fit a distinction after-the-fact.
But I personally do think of the Elisp world as split into various "layers":

A- The core language itself.
B- The core standard library.
C- Extra libraries bundled with Emacs.
D- Extra libraries distributed in GNU ELPA.
E- Extra libraries distributed elsewhere.

Yet, I would be hard pressed to draw the separation between some of
those layers (and more so to "define" that separation).

Great example: putting it in (B) makes sense, yet at the same time I'd
put buffer-local variables in (A), thus breaking the layering.

There are other implementations of Elisp, some of which are not tied to
an editor, so it can make sense (see the paper Mike Sperber and I wrote
for HOPL-2020 for an example).

This is a legitimate worry, but you have to balance it against consistency with other applications.  When I change my desktop theme, icons change in most apps, and the same concept gets the same icon in all apps.

Emacs is partly like that, partly not: some icons change and some don't.

We can have a discussion on whether to use a unified icon set on all platforms, but in the meantime making Emacs' behavior consistent would be a plus, and should be an easy change.

No, the icons looks different across themes. Hence the whole notion of 
"icon themes". But the set of icon names is fairly stable. This is what 
we'd be relying on.

See x-gtk-stock-map for some more detail.

Right. It's already not the case.

People have been doing all right regarding that. At least, I haven't 
seen much criticism of GTK's approach in this regard.

The window looks are different between platforms anyway. As well as such 
fundamental thing as the placement of window's close/maximize/iconize 
buttons.

On GTK, we're already there. Since 22.2, apparently. Only we haven't 
been paying attention to keeping this feature in proper maintenance. I'm 
guessing because some of our core developers use other platforms, others 
build with Lucid, and the reset disable the toolbars? But that's not a 
good approach.

But a given theme is not available universally, not even with the same
toolkit, I guess?

Which is already bad, IMO.  But before we make this a rule rather than
an exception or a historical accident, we should think hard whether we
really want that.  Emacs is special in several ways, and one of them
is its commonality -- you have only ever learn Emacs once, on one
platform.  It's  why I can give advice on Reddit to people that use
platforms I never did.

So this will be a significant change in direction, at least in my
eyes, and the decision should not be made casually, let alone by
default.

No, not really.  They are extremely similar, actually, modulo a few
unimportant bells and whistles.  At least the parts that are relevant
to Emacs are almost identical.

I'm asking people to think whether we _want_ that.  That we are one
leg there doesn't yet mean we decided to do that consciously.  You are
suggesting to make that a policy, and that's a serious decision, IMO.

Apple publishes a set of system icons for macOS (and its other OS's, if
that matters to anyone) as part of it's Human Interface Guidelines. These
are tweaked and updated with OS version, but usually are stable over
several major versions. The current set can be found here:

Indeed, it isn't. Although there's always the standard theme for GNOME 
(Adwaita) and the latest Ubuntu theme, we can look at those.

I'm not sure how that's important, though.

First of all, I'm suggesting we fix how the icons look in the GTK build.

Then you are welcome to discuss whether macOS and Windows could use 
something like that. And whether they should. Since you're skeptical of 
this approach from the outset, I'd rather bow out of that discussion.

Spacemacs, Doom, and Prelude (to name just three of the more popular
options) all make this work out-of-tree, so it certainly seems possible.
From my reading, the first two (at least) are strongly expected to be
customized after installation, and to have those customizations survive
updates of the "kit".

Spacemacs in particular adds a "layer" concept to emacs customization so
that bundles of related options/code/packages/config can be turned on or
off as a group.  Details can be found at:
https://www.spacemacs.org/doc/LAYERS.html. I would personally hope that we
could streamline this process, which seems pretty bulky from the outside.
Maybe inviting the Spacemacs people to share their experience that led to
creating their layers system would be helpful to us both. (I would have
CC'd them onthis message, but their team seems to be heavily based around
github (pull requests, gitter sharing, etc.), so it's not obvious to me
whom to contact. I can look into finding a contact if people think it's

I would agree with this "not really" sentiment, but extend it to include
the differences between icon themes, and where such things work at the OS
level, between OS's. The point of icon themes is to make them all fit
together, and the point of standardized system icons is to have them all
fit together, and the users have shown (for many, many years now) that they
understand this, and can handle the shifts with aplomb. Yes, it is possible
for someone to install a wacky gui-customization pack that changes the
left-arrow into a sausage and the file-folder into a rainbow, but the only
people who do such things are askign for exactly that behavior, and aren't
going to be upset that emacs' toolbar changes along with everything else.

As a practical matter, emacs will need a set of reasonable fallback
defaults, for systems that don't have system-wide settings; we can continue
to use those when the gui environment doesn't help us. The result will
certainly look no worse than the current mixture of icons one can find in
the emacs toolbar. It's very likely that we can improve that set of
fallbacks by adopting a single source for them, such as the GTK or KDE
options mentioned earlier.

A techincal wrinkle here is how those icons are displayed and how they're
stored inside emacs. By way of example, the two KDE icon sets that were
suggested (Breeze and Oxygen) use different file formats: one uses PNG
images; the other SVG. (Oddly, the SVG images are distributed in several
different sizes, which would seem to belie the advantage of using scalable
images in the first place.) Scalable icons like SVG would be nice for the
current era of high- and low-density displays, but my understanding is that
SVG is the least well supported image format inside emacs across our
various platforms these days.

Fixing them by replacing the current icons with prettier ones is okay.
Using the toolkit icons everywhere, as a matter of policy, is a
different matter.

Forget MS-Windows and macOS, that's not my worry right now.  IIUC,
your suggestion was to use whatever native icons each toolkit offers
on Posix platforms as well, and it wasn't limited to GTK.  That is the
decision I was talking about.  I myself have no strong opinions on
this, only weak ones.  But no serious decision-making should happen
without a "red team" on board making sure we don't fall victim to
groupthink simply because no one dares to ask a question about the
nature of emperor's clothes.  I tried to present arguments to the
contrary with that in mind, so people could consider both sides.

There's no argument that having a capability to change the set of
icons as part of a theme would be a good feature for Emacs to have.
So arguments for having that are, from my POV, preaching to the choir.

The argument, or at least its part about which I expressed concerns,
was to use exclusively the icons provided by the toolkit+desktop that
happen to be in use.  That's an entirely different matter, if we want
to make it pour policy.

Only if we decide we _want_ to use those system-wide defaults where
they do exist.

They aren't.  They are separate image files which we load when needed.
And I think it should be left that way, because it will make it easier
for us to include new icons in the distribution.

SVG is IMO a PITA because librsvg is a monster.  But other than that,
SVG images are a fait accompli, and we need to support them well.

Adding a user option disabling the toolkit-desktop icons and switching 
to the fallback shouldn't be too hard.

But I think it's worth our effort to try to integrate first. It's what 
users generally expect from applications, and the effect is that the 
program fits the desktop environment better. I hear this sentiment is 
particularly strong among macOS users.

I’ve used Spacemacs for quite a while back in 2017 when I just started using Emacs. It’s more of a gigantic community-driven config than an out-of-box for-dummy kit. What I envisioned is more like what VSCode does: automatically installing appropriate packages and downloading and setting up external programs. I would use it if there is such feature - many of my configs are just (use-package package) with some code adding hooks and auto-mode-alist.

Some ideas: 
1. Is it ok to include MELPA (opt-in) as one of the mirrors? Say a newbie type M-x auto-package-mode, and boom, all the auto installing package features are on, and MELPA is added to package-archives. 
2. Could Emacs downloads some external programs (like LSP servers) for users? I would definitely let Emacs do the dirty work if it works reliably. But maybe there are security/maintenance concerns.
3. It would be cool if Customize can customize mode hooks and auto-mode-alist and other usual stuff.

It seems like most elisp packages could come with a standardized "Here's
the normal setup for this mode/package; would you like to run it now, have
it run on each startup, or see a new buffer where you can examine it now?",
analogous to how customize-theme prompts to
disallow/allow-once/allow-always code upon loading the theme. (Honestly, I
assume this never happened because most emacs devs seem to prefer
managing snippets of elisp over using customize.) Use-package gets part of
the way there; seems like it could easily get the typical setup hooks for a
package from the package itself.

If Customize can provide a interface, I’m sure packages will (slowly) adapt to it, just as they adapt to defcustom.

> (Honestly, I assume this never happened because most emacs devs seem to prefer managing snippets of elisp over using customize.)

Mainly for maintenance reasons, I guess. Custom file is usually not version-controlled. That’s not necessarily a bad thing, I find Customize useful for storing local configurations that could differ between machines (executable paths, etc). Maybe Customize could separate into two files, one version controlled, one local. And I can put many of my random setq’s into Customize.

That plan for a manual for the word-processing feature makes sense.

It appears that what people call "Org mode" is a collection of diverse
features, and what they have in common is use of a certain format of
the text.  Is that right?

I have to question the practice of treating these diverse features
conceptually as a single mode.  Although I still don't know what those
features are, if one of them is a word processor and the others are not,
they are too different to make sense conceptually that way.

It would make more sense to call them various different modes.  That
they all use a certain way of formatting the text may not be important
to mention.  If it is useful to have a name for that, I suggest the
name "Org format".  Each of these modes could say it uses "Org
format", or perhaps a variation of that.

Maybe that is how things are now, but is there a reason why things
SHOULD be done this way?  Does each of these features need to support
"the whole Org syntax"?

It could be that the simple way of implementing them is by sharing code
that implements "the whole Org syntax".  If so, I won't argue against
sharing that code.  But it may not be useful to TALK about the fact
that each one implements "the whole Org syntax".  And it is possilble
that it is better to share only part of that code, not all.

In other words, if we don't let the concept of "Org mode" shape our thinking,
we might thing of these features differently.

I wonder what kind of effect it will have on the community when
packages in the same domain compete to be "anointed" as the package that
Emacs shall recommend for a particular file type or feature.

Or do we approach it like the EU did with web browsers, and when Emacs
boots, we suggest either enabling Ivy, Helm, or Company for text
completion? There are never more than a few packages seriously competing in the
same domain anyway, if one can even call it competition.

Looking at the amount of currently maintained elisp packages online
these days, I suspect Emacs actually has more users than ever, it is
just that our segment of the overall market is smaller.

Let's say tomorrow Emacs is like VS Code running Emacs Lisp in a Guile
VM. Is the idea that if we compete in the same modes as the modernist
editors, we can steal enough people from them that we will advance the
cause of free software?

That's not a rhetorical question, I am curious. Right now with the
status quo, we know we are at least satisfying a core audience that has
self-selected themselves as Emacs users through the hazing that is
figuring the damn thing out.

Playing towards your core audience has both benefits and drawbacks.

The practice has probably arisen historically, but IMHO it still 
makes sense to do so now, because probably Org's biggest strength 
is that the various features are tightly integrated. That doesn't 
mean you couldn't use Org for just one of its features, you 
definitely could, but the beauty of the system is that the 
different features aren't strictly separated.

For example, Org can be used as an agenda, to keep track of your 
appointments, daily schedule, etc., much like Google Calendar and 
other such offerings. At the same time, you can use Org to write 
your papers.

Now, you would normally keep your appointments in one file, say 
=agenda.org=, and the paper you're working on in another file, say 
=paper.org=. So far, so uninteresting. But with Org you can put 
TODO notes in =paper.org=, add deadlines, date and time stamps, 
etc., anything Org supports. Then, when you display your agenda 
(i.e., run a function that takes the contents of, in this example, 
=agenda.org=, and creates a nice overview of it in an agenda-like 
fashion), you can have the TODO items, deadlines etc. from 
=paper.org= included in this overview automatically. Try that with 
Google Calendar.

This is just one example, but it illustrates the whole point of 
Org: the system has many different features, and they all work 
together.

Actually, it's crucial to mention that. You might say it's Org's 
raison d'être. It's what makes integrating all of Org's functions 
so tightly possible.

I think it would certainly help newbies getting started with Org 
to document its features separately. Eli's suggestions for 
restructuring the Org manual sound very good. I had a difficult 
time getting started with Org myself, and I can relate very well 
to the impressions that you and Eli describe.

But at the same time it should be made clear from the outset that 
Org's strength lies in its integration. I mean, I could use 
Markdown with Pandoc to write my papers, *cough* Google Calendar 
*cough* to keep track of my appointments, Jupyter for keeping 
programming notebooks and *cough* Evernote *cough* to keep notes, 
but there would be no way to link all of that. With Org, there is.

By the way, etc/images/README says:

* The default GTK icons were not overridden by the GNOME theme due to
a bug which was fixed in GNOME 2.15. Once GNOME 2.16 is in wide
circulation, the GTK icons should be replaced with the equivalent
GNOME icons.

Does that mean there is some action that was planned but never
performed?  Gnome 2.16 was released in 2006.

Emacs on my macOS machine seems to use the icons from etc/images.  On
GNU/Linux (GTK) there is a different set of icons which arguably look
more "modern".

I think we should offer a multiple choice question, ideally with some
brief explanation of the differences between the packages.

It would also be good if one could easily switch between alternatives.

Of the many implementations that I see listed there, most are from the
"let's rewrite Emacs (in our favorite language / better)" camp, and do
include some (or most of) the editing primitives.  Of the others, I
don't really see Emacs Lisp, but a glorified MacLISP with optional
lexical binding and some Emacs Lisp-ish features.

I suppose we're operating on different definitions of what constitutes
"Emacs Lisp".

+1.  I used Emacs for a long time, but I didn't adopt Org until a long
time after its release (2013, 14 or so) or so, and even then the manual
was showing its age.

It's common practice for GTK themes that change the look-and-feel a lot
to provide an accompanying XDG icon theme, and that's what the icons in
`x-gtk-stock-map` obey.

Sure. But also how about just "help more people enjoy Emacs's power and

We don't really have to compete for the _exact_ same audience. But we

More or less, AFAIK.  The common features are more than just the

It may be too late to actually separate the various features,
especially since there doesn't seem to be anyone who'd want to do this
(very complex) job.  I think it would be a very useful step if the
documentations and the general classes of the Org features would
present to the users several disparate sets of capabilities, and would
allow users to learn and use only the set(s) they need.

We have several of such "competitors" already in core.  Did anything
bad happen?

And it isn't like packages are lining up to be included in Emacs, or
even "anointed" by it, is it?  Boy, I'd like to be there.

More users generally means more contributors, more future developers,
and better Emacs.  And yes, it advances the cause of Free Software,
like any other free package that attracts users.

If features are well integrated and work together well, how is it
important to know that they do it because of a certain way of
formatting text?

You are actually describe the strength of Emacs as an integrated
package whose parts work well with one another.  And yet we have
separate manuals for major parts: Gnus, Org, Eshell, etc. -- just look
inside doc/misc/.

IOW, I don't see a contradiction here.

Why are so many great packages not trying to get included in GNU Emacs? WAS: Re: Making Emacs more friendly to newcomers

I strongly agree.  In fact, I would go so far as to say that this is an
important strategic consideration for GNU Emacs.

It's very unfortunate that there are so many great packages that are only
available to a subsection of users willing or able to install third party
packages.

It's too easy for package authors to just throw it up on MELPA and be done with
it, without realizing the many benefits of getting it into GNU Emacs.  There
would be some great benefits to having more deserving packages in core, or even
GNU ELPA:

- They would reach a wider audience.
- We can do more to ensure they integrate well with all other packages.
- We could consider enabling some of them by default.
- We would have a world class team of Emacs Lisp hackers (in other words,
  emacs-devel) reviewing the documentation and code.
- etc., etc.

The reasons why package authors would not want to include it, on the other hand,
could obviously vary.  Some of the reasons I have seen are
unfortunately very shallow:

- Misconceptions about how hard it is to work with emacs-devel.
- An unwillingness to assign copyright to the FSF, seemingly often more due to
  inertia than any principled opposition.
- Strongly ideological anti-FSF sentiments (often disguised as "non-ideological"
  or "practical").

I mean, that's my impression of it, and I'm not pretending that this list is
exhaustive or even generally correct.

But maybe we should think about how we can argue our case more strongly, and
clear up at least some of the misconceptions.  For example, we could make
additions to the Emacs Lisp manual on why one would want to push to have their
package included.  We could also explain that they can have their code in GNU
ELPA, or even GNU Emacs, and host a development repository anywhere
they like, etc.

In Windows there are no standard icons, but a few ones signifying
warnings
(https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-loadicona)

This said, there are some DLLs that have broad sets of icons and that
are available, some since Windows 95, some since Windows XP. They have
not changed and can be used
https://www.digitalcitizen.life/where-find-most-windows-10s-native-icons
This webpage provides a reference by library and code
https://diymediahome.org/windows-icons-reference-list-with-details-locations-images/
However, the default set of icons is obviously deficient in that it does
not provide the icons an editor application requires: open, save, print,
etc.

Definitely I would not recommend this path, but I would encourage having
some higher resolution icons available in PNG format, for those who use
them (I disable toolbar in my computers).

I've made an attempt, but the discussion is about copyright and 
providence of files, whereas the note seems to be about some functional 
problem.

I don't really understand it what it recommends we do now. It would seem 
as if GNOME icons can override GTK ones now (in some case where it 
couldn't before (?)), we could distribute GTK icons now and rely on 
GNOME to override them as appropriate?

That's something that documentation can fix.

It has been mentioned a number of times already.

I think that the process could be streamlined (and there is a need to check that with the legal team I guess).

For one, the actually *submission* of the copyright assignment to the FSF could me made to be as easy as a simple code commit, signed with something like a gpg key or something.

Once the developer has simply "pushed that button," the contribution should be considered valid, and then eventually the developer receives a PDF signed by the FSF to confirm the assignment.

And that should be it (or are there cases when the FSF refuses the assignment ?)

Hahaha :) I'm not sure a REOPEN YOUR CODE meme would pass muster in our times, but it seems to me that there is some overlap between populations that reject the FSF "because freedom" and those who reject sanitary lockdown "because freedom". But I won't err on that path any further :)

 I'm not sure how. I think the widespread conception is that working with
emacs-devel is more difficult than working with many, many other free- and
open-source projects, and I think that conception is correct. Compared to
"fork the project and submit a pull request" or "publish a package on
melpa", following emacs' patch guidelines is harder. Emacs requires
additional paperwork. Updating the documentation (NEWS, Changelog, the info
manuals) is harder and involves tools, tech, and practices that are
unfamiliar to most potential developers. Using debbugs has improved a lot
in the past few years, but is still a pain-point for many. Following the
emacs-devel mailing list is, let's say, not a welcoming experience for
everyone. That doesn't even touch on the difficulties of interacting with
the core.

I think that the end result of emacs' processes is high-quality code that
runs on many more systems than the vast majority of software, but I don't
think most new developers are shying away from working on emacs because of
the lack or quality of the documentation.

That depends on where you come from. A lot of people have not been contaminated by the entitlement that comes with the "I'm sending a PR, please check it in" generated by the Github culture. I'm not saying that PRs are bad, just that a lot of people think that whatever they do is OK.

Documenting means stating that Emacs is not just another "open source project you can contribute to in the weekends" (although that's also possible). It is Free Software and it is robust and it is here to last. All that comes with requirements and that's fair.

> Compared to "fork the project and submit a pull request" or "publish a package on melpa", following emacs' patch guidelines is harder.

Please. As a totally non-developer I was able, with the guidance of a lot of people here, to follow the rules and get some code in the emacs core code and in package.el. Yes, it is harder because the requirements are different.

I proposed a solution in my suggestions.

And if they can learn emacs-lisp enough to contribute something, they can certainly learn a few extra things.

Maybe we're not talking about the same thing ?

When I say document the process, I mean putting it in nice colors on the web site, so as to ease the pain for people who are used to nice colors on web sites but who can still go deeper and commit themselves to serious code.

You may see that as an advantage, but I consider it a drawback.  The
"tight integration" of these different features is an obstacle to
learning to use one of them, or even finding out about one of them.

*We need to make them separate.*

Separate and integrated are not opposites.
It is possible for several features to be integrated,
in the sense that they work together _when you want that_,
and also separate, in the sense that we describe each one separately
and you can learn about one without paying the slightest attention
to the others.

I would say that is the complexity and obscurity of the system.

I think we can make them clearly separate, for purposes
of documenting them, without reducing the ability to integrate them
for users who use more than one.

I can see that that integration is useful -- but _the fact that it
applies only to "parts of Org mode"_ makes it also a a limitation.
It is a drawback that _only_ the modes that are "part of Org mode" can
integrate with these features -- and the rest of Emacs cannot do so.

Instead of dividing Emacs facilities and modes into the "Org
first-class modes" and the "Org second-class modes", we should make
all modes equally able to integrate in these ways.

People who want to use a specific one of these facilities don't need
to know that.  It is useful for those users who want to use more
than one of these facilities together -- but that should be
an advanced topic.

Are you assuming that this means a lot of change in the code?
I have no idea whether it does.  Maybe most of the change needed

the change in documentation.

Thanks for the list. Below is a patch that makes use of it.

Unfortunately, it doesn't. Nothing for "save-draft" either, but we're 
currently using the "gtk-close" icon for that.

Also, I dug a little deeper into that rabbit hole, and turns out, Gnus 
normally defines two sets of icons for its toolbars. The first is called 
"gnome", and the other is "retro". And in 2016 the relevant check was 
reverted (commit d88118db37d), so we've been using the "retro" version 
since. I'm guessing Lars doesn't use GTK or toolbars at all.

It seems the two versions of toolbars have diverged in contents too, so 
aside from reverting a part of that commit, someone will need to do the 
work of merging them. Hopefully into one.

Anyway, here's the patch improving the icons a little:

How many subscribers do these mailing lists have?

For comparison, the StackOverflow surveys we've seen mentioned in this 
thread count about 4000 dedicated Emacs users (that filled out the 
survey). The Emacs StackExchange site has around 20'000 registered 
users. The Emacs subreddit has almost 40'000 subscribers.

With Emacs, my experience has been that (1) and (2) are the most common
reasons, with (1) being slightly more common.  I don't believe I've seen
anyone refuse to assign copyright to the FSF over (3) for Emacs packages
in a long time.

Because the user has to format that text. :-) Sure, there are 
helper functions for a lot of things, but as a user you do need to 
know the Org format.

Yes, but it's a different level of integration. I need a decent 
working knowledge of Elisp to be able to integrate Gnus and 
Eshell. But I only need to know Org syntax in order to integrate 
my TODO list, task management and writing with my calendar. The 
point is, I need to know Org syntax anyway to do each single thing 
separately. Integrating them doesn't require a deeper level of 
knowledge than I already have.

I'm not saying there's a contradiction. If that's how I came 
across, then I didn't make my point very well. Like I said, I 
think the Org documentation would benefit greatly if your 
suggestions were implemented. It's just that the fact that Org's 
different parts are tightly integrated should not be tucked away 
in some "Advanced Use" section of the manual.

No, it really isn't. It's just the way the current documentation 
is set up that makes this difficult. (I know, I agree, I've been 
there.)

That sounds good in theory, but I'm really not sure what that 
would mean in practice. (I'm not entirely sure that you do either. 
;-) The reason Org's facilities can be so tightly integrated is 
because they all use the same Org syntax. Org files are just plain 
text files with a well-defined markup, after all.

As for integrating with the rest of Emacs, any part of Emacs is 
free to make use of this syntax as well, Org in fact provides 
libraries to make this easier. For example, I maintain a package 
for managing .bib files. It integrates with Org in that the user 
can add notes to bib entries, which are kept in Org files, and the 
user can maintain a reading list, also as an Org file, which then 
integrates with the user's TODO list and calendar, if s/he so 
wishes. I started this package long before I ever heard of Org 
mode, but it was easy to add this functionality once I realised it 
would be useful to do so.

So I believe the kind of integration you talk about is already 
possible, you just need to write the Elisp code to do it. In that 
way it doesn't differ from all the other facilities that Emacs 
provides: if I want to integrate Gnus and Eshell (whatever that 
would mean), I need to write Elisp code.

This of course contrasts with the integration of the various 
facilities that Org provides, because that only requires knowledge 
of Org's syntax. But I believe that's OK and fully expected: the 
things Org can do are closely related and many people *need* them 
to integrate well with each other. So integrating them should be 
easy.

On the other hand, what Gnus does has little to do with what 
Eshell does and scenarios where it would be useful to integrate 
them are probably rare. So it's OK that that's not so easy to do, 
as long as it's not impossible.

Sure, but I don't think it's a big cognitive burden for them to 
know that. Pointing out this fact in a couple of crucial places 
wouldn't take more than a sentence or two, with a reference to a 
section where it's all explained in more detail.

>  It is useful for those users who want to use more

> an advanced topic.

No, it shouldn't be billed as an advanced topic, for two reasons. 
First, it really isn't advanced at all: like I said, you really 
only need to know Org syntax in order to integrate these 
facilities, and you need to know Org syntax anyway to be able to 
use just one facility. Second, the tight integration is one of the 
reasons people are attracted to Org mode in the first place, so 
it's likely something people will look for in a manual early on.

Anyway, I think this subthread is slowly getting out of hand. :-) 
I don't believe our positions are as far apart as the discussion 
might suggest. I do agree with you and Eli that it would be very 
helpful if the Org manual were structured along the lines Eli 
suggested. I envisage an introductory section that clearly states 
the different use cases of Org and directs the reader to separate 
sections for each of them, which should all be written from the 
point of view of a new user, i.e., they shouldn't assume 
familiarity with any of the other use cases. At the same time, the 
introduction should mention Org's integrative nature and point the 
reader to relevant section(s), without labelling these as 
"advanced".

Whether and to what extent the Org code base should be modified, 
I'm not qualified to say, but given the limited resources, it 
isn't likely to happen anyway. Improving the documentation would 
be a much better investment of time.

Commit to what repository?

The assignment form requires one to file a couple of personal details
that are unlikely to be possible to be gleaned from a commit.  In some
situations, the assignment needs a disclaimer from the person's
employer to go with it, something that again is unlikely to be
triggered by any commit anywhere.

I believe these aspects of the copyright assignment process are the
ones that require a separate communication between humans.  Of course,
if it can somehow be simplified, I'm all for it.

I think it's more correct to say that Org features are well
integrated, not that they are tightly-coupled in the sense that they
cannot work separately.  I did (and do) successfully use a couple of
Org features although I know and need very little of the rest.

I think we should try changing the documentation first, as that is a
Good Thing anyway.  When that is done, we could consider whether any
code changes are needed.  (I actually expect that to become evident
while the documentation is re-written in the directions I proposed:
whoever will do that job will discover that, for example, to be able
to produce a stand-alone document with Org, one would need features
that currently belong to some unrelated Org part -- which would mean
some code needs to be added or modified to make that feature
seamlessly available to document-writers.)

Unless I misunderstand what you mean by "Org syntax", I don't think
users who want to create documents with Org should be required to know
that syntax.  Instead, there should be commands to help them produce
correctly formatted snippets.  Compare that with Texinfo commands
which produce the various syntactic elements of the language.

I'm not sure what you mean here.  AFAICT, there are already several
such commands.

- To insert a new headline, type 'M-RET'.
- To insert a source block, type '< s TAB'.
- To insert org export headers, type ''C-c C-e #'.
- To schedule a headline for later, type 'C-c C-s'.
- To insert a link, type 'C-c C-l'.
- etc.

Yes, there are usually helper functions to do just that, though 
for some things, it's easier to just type the markup directly. 
(`*bold*` is IMHO quicker than `C-c C-x C-f * bold C-f`.) But once 
I know how to create a heading in a text document I can use the 
same command to create a heading in a notes file or an agenda 
file.

Then it seems like I was right: there's no need for users who want to
produce documents with Org to be proficient in the Org syntax.  Right?

Command efficiency aside, if such commands exists, then why would the
user need to know the Org syntax which they produce?

And that 'little' extends to the Org syntax: there is no need to know
all of it, or even a large part of it, since basic use just requires
something like:

    * Heading level one
      Text

    ** Heading level two
      Text

    * Another heading level one

    ** TODO do some stuff

Itʼs only when you start wanting to change org's default behaviour, or
generate a custom agenda, or schedule TODO items, or track task time
usage etc, that you need to learn more.

That depends on what you mean by 'stand-alone'. The built-in Org mode
from 'emacs -Q' can export to at least html, latex, pdf and odt by
default, of which only latex and pdf require the installation of extra
external tools.

Thereʼs a texinfo backend as well that youʼd need to enable, which may
well require external tool support (Iʼve never used it).

That's orthogonal.  By "stand-alone" I meant a document that doesn't
require support from any additional Org features, like TODO notes,
calendar appointments, etc.  Just a document that includes structured
text.

None of those additional features are *required* for a document. All
you need to produce a document is org-markup, like

    This is some *bold* text, this is some /italic/ text, and this should
    be =monospace=

You donʼt even have to use headings if you donʼt want to. Or
footnotes. Or links. Or inline latex. But you *can* if you want
to.

I'm not surprised.  But it could be that some minor feature will still
need something.  Like adding footnotes and links, perhaps?  It's all
should become clear once composing documents with Org is documented.

Itʼs all text, so you can add those manually if desired. But org by
default has keybindings for both of them :-)

Eli, does this name length matter any more?

Is the Emacs Lisp Intro long enough that it needs to generate subfiles
named with two digits?  Could we make it generate suffixes -N instead?
Then we could call it ELINTR.

I can only guess. I was wondering if my rough intuition was true, 
though. And I think comparing the numbers might give us insight into 
which fraction of our users is really comfortable with email as a 
discussion medium.

Pretty much. Reddit also has a "polls" feature, where it could aggregate 
the answers for us. They also have comments for when someone wants to 
leave an additional explanation.

Because handling thousands of response emails (which is what might 
happen if people are interested enough) by hand is too much, I think. 
Even just a few hundreds.

> Have you got any other suggestions of places?

The ones I mentioned are the biggest ones I know.

Speaking of the default values, what do you think about using your 
scenario to ask the users about their preferred value of 
indent-tabs-mode? I can create a poll with four options: "strong tabs 
preference", "strong spaces preference", "mild tabs preference", "mild 
spaces preference". People can add extra explanations in comments.

This particular subject has endured some heated discussion in the past, 
and we never managed to agree enough to change it. But we never asked 
the users at large either. According to my data, most of them should 
prefer spaces.

If I do create a poll, and the outcome would strongly indicate a change 
of the default, we'd pretty much have to change it then, though.

No.  Especially since we stopped splitting our manuals into foo-N
parts long ago.

The only issue today is that renaming the Info file will make the
successful update of the system-wide DIR file by install-info at "make
install" time more important, otherwise people might have an old
manual presented to them.  Not sure what this means for the various
binary distros.  Also, we need to rework all the references we have to
that manual in Lisp files (I found only one such reference, FWIW).

Not an issue anymore, see above.

> Then we could call it ELINTR.

I'd suggest ELINTRO or even LISPINTRO (similar to LISPREF for the
ELisp reference manual).

FWIW, I don't agree with that conclusion, in the abstract.

[ But I do prefer spaces-only, personally.  And beyond a
preference for using that within Emacs, when pasting code
copied from Emacs into other apps (e.g. Q&A on the web

If the poll doesn't contain an implicit promise (e.g. "we considering a 
change of default"), the turnout is likely to be much lower. Which is 
not what we want, I think.

I agree.  I would add I think this could be an important way for
emacs-devel to interact with regular users, and make them feel more
involved.

I don't want to come across as negative towards your suggestion to
create a poll, which I think is an excellent initiative.  But perhaps
we could consider if there are more pressing or engaging questions to
put before our users.  The tabs vs spaces debate feels a little bit
dated, at least to me, and possibly not even that important since it's
so easy to configure to your liking.

Perhaps we could even consider asking for their input on a number of
important questions (not too many, say 4-5) where it would be
interesting to get feedback.  Ideally we would try to choose questions
strategically to inspire excitement for Emacs development.  (Tabs vs
spaces could of course be one of them.)

Just some food for thought.  Either way you decide, I'm sure I'll be
happy with the outcome.

tl;dr: Poll results are one, and only one consideration.

---

An implicit promise to consider is not the same thing
as a position that a poll outcome strongly indicates
that the default should be changed.

It may or may not strongly indicate an opinion by the
people who responded, and that may or may not be
strongly relevant to the question.

And just having a poll suggests that there will be
consideration of the poll results, and that such
consideration could include the question of changing
the default.

And if the question of default change is really part
of the question at hand then it should be explicitly
part of the poll.  E.g. not just "What's your use or
preference, personally?" but also "Do you think your
preferred behavior should be the default behavior?

The point is that default-changing is (should be) a
case-by-case decision.  And it can be (and usually
is) based on multiple considerations - not just a
user poll.  One question about polls is their
representation, who the responders are, what their
relation to the question (e.g. their use of Emacs)
is, etc.

I said I didn't agree with your conclusion _in the
abstract_.  That's the problem with it.  It might
be a reasonable conclusion in some particular case
(some particular poll question).  But it's not
reasonable as an abstract proposition.

I don't know about that. It's definitely not urgent, but it's a fairly 
simple question (unlike some others we might ask), and I think the 
default behavior of mixing tabs with spaces constitutes a point of 
confusion for new Emacs users to this day.

I think we should only ask one question at a time. Creating multiple 
polls is an option, of course, but we could just as well wait a little 
between them.

And if indent-tabs-mode is not important in your opinion (it's just the 
first thing that came to my mind), do you want to come up with some 
other questions?

Super User is limited in the number of Emacs questions, certainly (1,643 questions).

Stack Overflow is NOT limited.  It has 16,700 Emacs questions.  emacs.StackExchange has 18,717 questions.  In other words, they are about the same size.  And there's a fair amount of overlap in the kinds of questions they have.

But the number of questions is only one consideration.  Each of those Stack Exchange sites offers a different mix of users.

In particular, the users of those other sites are programmers of all sorts, people for whom Emacs is not necessarily the be-all and end-all of their lives, people who often primarily want to use Emacs for programming.

That's important, I think.  Emacs questions on Stack Overflow may be less oriented toward things like Org mode, image display, faces, etc., and more oriented toward programming.

We want to reach all kinds of Emacs users.  Programmers are a key user group, and many programmers are more likely to ask an Emacs question, or a question that touches on Emacs, on an SE site other than emacs.SE.

And beyond the sites I mentioned, there are other SE sites that have Emacs Q&A, and still others that have Lisp Q&A that is relevant to Elisp.

An SE poll on a site other than emacs.SE should of course be tagged `emacs`.

How does one make an SE poll, though?

RE: How to poll the users

[Drew Adams]

> How does one make an SE poll, though?

No idea, sorry.  Sounds like a question to be
posed at https://meta.stackexchange.com/.

Well, maybe not.  Searching there a bit I came
across these, which suggest that SE user polls
are not welcome, in general:

https://meta.stackexchange.com/questions/186530/what-close-reason-for-polling-questions

https://meta.stackexchange.com/questions/233908/are-poll-style-questions-ever-acceptable-on-meta-sites

You had said that Stack Overflow (or Stack
Exchange) does polling, and that's certainly true.

But that's the site itself.  It looks like there
may be no good way for someone outside to post a
poll there.

The idea of a poll is to understand the effects of the various
choices, and find out the specific reasons for users to prefer this or
that, and evaluate their significance -- NOT to count how many people
prefer each choice.

It is a mistake to count the answers, because a given change can
affect one user very often, and affect another user only rarely, but
they might both state a "strong preference".

In this context ("FSF requires that each author of code incorporated in
FSF projects provide a copyright assignment") "provide" is correct (here
corresponding to the subjunctive in French), especially in formal
registers of English, though many people don't use this in everyday
speaking or writing.

Like Drew described, StackOverflow discourage polls and will likely 
close them as non-constructive. It's a Q&A website, and they don't want 
Q that can elicit an unbounded number of A's.

A numbering poll is still somewhat useful, if only to get the general mood.

But in the description we can ask everybody to actually write a comment. 
*Or* upvote one of the existing comments, if it reflects their 
experience accurately.

Both these options together seem to make responses over email (which 
would otherwise be invisible to the public and thus miss out on the 
chance to spur some discussion) unnecessary. But we could also encourage 
people to write emails, if you so prefer.

I think the time when it affects the users the most is just after Emacs 
is installed for the first time, before they know about this variable, 
and how to customize its value to nil. So it doesn't affect people 
"often", but it does affect a lot of people.

If I was to design a series of questions, they would probably be about
more "soft" aspects of the project, regarding things we are discussing
in other threads: how to get more people involved in Emacs core
development, contributing to GNU ELPA, etc.  Of course, nothing is
resolved with merely sending out a poll, but I imagine it would help
gauge the situation and make us feel more confident about which
direction to take.

I think we've had those discussion on Reddit many times before already, 
and some of it comes down to doing the work (e.g. setting up GitLab in a 
way to keep both the wolf and the sheep happy, which is a lot of work, 
in this case).

Maybe some more, more specific questions could lead to new insights, though.

RE: How to poll the users

[Drew Adams]

tl;dr:

 Announce polls widely, beyond GNU ways.
 Have users participate only through GNU ways.

My suggestion would be to perform polls as
you described in the beginning, i.e., how it's
been done in the past.  (See also below; this
could be enhanced.)

But it would be good to _announce_ a poll in
more places than just the Emacs mailing lists.

A poll can be _announced_, with instructions
for participating and an indication of what
the poll is about, on non-GNU sites such as
those mentioned so far - Reddit and the
various Stack Exchange sites (especially
emacs.StackExchange and StackOverflow).

Plus an announcement by Sasha on her blog and
her Emacs-news mail to emacs-tangents@gnu.org.

Announcing a poll in various places, providing
the same info about it, including how to
participate and what is expected, and then
having all users actually participate in more
or less a single location/way, which is
managed by GNU, would be good, I think.

That way to participate could be just what
has been done in the past - by email.  Or it
could be by way of a GNU Emacs website.  Or
by any combination of GNU-controlled methods,
as long as they all feed into the same poll.

I've already opined on downsides:

everybody having to write the same thing again and again,
closed-ness to the public (you or I can't read the actual replies),
and in the event that a significant number of our users really choose to 
participate, it will result in a crapload of messages that a single 
person has little hope to sort out.

And if every such poll will requires a special setup (configuration by 
the admins, etcetera), it will limit our ability to do them.

I don't see how all of those downsides couldn't be
mitigated, providing a GNU site or other means to
serve as single collection point, echoing point
(echoing current counts, text suggestions, etc.),
and even providing a discussion venue.

Nothing says that we need to prevent the public
from seeing the poll results, including comments,
for example.

The point of my suggestion was to not try to have
such polling (interaction, counting, reporting)
be repeated (and likely in differing, possibly
conflicting ways) on sites outside GNU - and
instead to just _announce_ a poll on such outside
venues.

To be clear, nothing should prevent also discussion
etc. on such non-GNU venues.  The point is for GNU
to count, echo, and provide discussion via a GNU
site/mechanism.

IOW, don't try to reproduce the polling here, there
and everywhere.  Just announce it here, there, and
everywhere.  Anyone who wants to discuss a poll
here, there, and everywhere is welcome to do so,
but that discussion will not automatically be
captured as part of the poll itself.

Just one suggestion.

I'm not saying it can't be done. I'm saying it hasn't been done, and in 
all likelihood nobody is going to do it.

I say just do it on Reddit. Any traffic on the mailing list (which I see 
no reason to discourage) will pale in comparison.

A poll of the users is not about counting votes.  The aim is to learn
more about what users find convenient or inconvenient, and especially
how and why it is convenient or inconvenient.

The ideal outcome is NOT that we choose the default that 65% of the
users prefer rather than the one 25% prefer.  Rather, the ideal
outcome is to invent another option that nearly everyone will like.

The only proper "promise" to make is that we will use what we learn
from the poll to make Emacs better.

Responses of "yes" or "no" are not very helpful, because they give us
little understanding.  We seek responses that tell us more than that.
To encourage users to think about and report why and how certain
behaviors help them or annoy them, we raise one issue at a time.

If there are several issues we want to learn more about, we do
separate polls about them.  We can do as many polls as we like,
subject to the limits on our time to study the results.

I think we should make sure polls do NOT turn into discussions.
Discussions would multiply the bulk of messages and we would not be
able to digest them.

Most of you are brainstorming about what we could do.
I have actually done polls several times.

Having each poll dump messages into its own file was reliable and easy
to set up.  It takes a few minutes to set that up.  It may take an hour
or two to write the posting.  It may take a few hours to study the
responses.  So let's not worry about the few minutes.

I think we should make sure polls do NOT turn into discussions.
Discussions would multiply the bulk of messages and we would not be
able to digest them.

Most of you are brainstorming about what we could do.
I have actually done polls.

Having each poll dump responses into its own file was reliable and
easy.  To set this up takes a few minutes.

It may take an hour or two to write the posting.  It may take hours to
study the responses.  So let's not worry about the extra few minutes.

THose points seem valid to me.

All that sounds good.  The more, the merrier.
(But who is Sasha?)

Nowadays we would want to make a web page with
info about the poll; we could post references to it
everywhere that makes sense.

That is the way that makes sense.

That would be possible in principle, but inconvenient to set up and to
use.  We want people to give complete answers, not force their
responses into a form.

There is no good option for that. The main way to post something there 
is to create a "New Question". Then this question will likely be closed 
by the moderators as "non-constructive" and the vast majority of users 
won't see it.

Only if we use the mailbox approach. And the downside of disallowing a 
discussion is missing out on valuable insights.

With the tools contemporary websites provide, polling is trivial. Many 
people have done it, myself included.

Can you digest, say, 2000 free-form emails in a few hours? And then 
summarize all expressed opinions accurately for the other developers to 
understand the results?

Or if you receive only 20 emails, can you have any confidence that the 
received feedback describes the community with any sort of accuracy?

And in this particular case, numbers are important as well. The 
arguments for and against indent-tabs-mode have been made numerous times 
(including the TabsAreEvil wiki page Drew has linked to). What we don't 
know well, on the other hand, is how many of our users actually use tabs 
for indentation in practice. If the fraction is minuscule, then changing 
the default value really shouldn't hurt.

Sacha Chua (cc'd - I spelled her first name wrong).

She regularly (e.g. weekly) posts an informal Emacs
News message to emacs-tangents@gnu.org (see attached).  
Those messages are also on her friendly blog page:

Improved welcome screen

[Stefan Kangas]

[-- Attachment #1: Type: text/plain, Size: 529 bytes --]

Dmitry Gutov <dgutov@yandex.ru> writes:

> Maybe some improvements to the welcome screen.

OK, so here's a proposal for a better welcome screen.  The idea was to
get rid of the impenetrable wall of text we have now by simplifying
it.

The attached patch is a quickly hacked together proof of concept, but
could be cleaned up and finalized if it's a direction we want to take.
I've attached a screenshot of the result.

You can test the patch using:
    ./src/emacs -Q --eval '(display-about-screen)'

Best regards,
Stefan Kangas

Definitely! Users are important.

There is an interesting interviw/article in Linux Format from January
this year with Ton Roosendaal, the creator of 3D modelling/animation
package Blender. Blender went form relatively non-popular 3D application
on the verge of extinction to become a multimillion industry accepted
application. He touches on tradeoffs Blender made between "old wyas" and
more accepted "modern standards" and importance to appeal to "masses".
In sense it touches on similar questions as Emacs is faced with, so it
might be an interesting read. Just as a side note ...

I like this direction quite a bit. Not crazy about the part after the 
dashed line, though, but it's less clear what we can replace it with.

The "NO WARRANTY" can probably just live in the Help menu. Or move to 
the middle. Maybe by replacing the "Ordering Manuals" item which could 
obtain more prominence in "(emacs) Top". Or by having a fourth item 
there. Maybe we can have 4 items in each column.

Speaking of the Guided Tour, EWW is nifty and all, but it renders that 
page worse than any normal browser.

Unless I made a mistake somewhere, the links have just been re-arranged:

- "Emacs Tutorial" and "Emacs Guided Tour" was renamed to "Tutorial"
and "Guided Tour".
- "Absence of Warranty" is moved below the dashed line, linked from
the text "ABSOLUTELY NO WARRANTY".
- "Contributing" was renamed to "Contributing & Bugs".

Other than that, I think all links should still be there.

Thank you, this is good feedback.  For this first draft, I tried to
include all information that was there before.  But I'm personally
happy to incorporate further changes along the lines you suggest.

As for the version information, we could just mention the major and
minor version in the first sentence:  "This is GNU Emacs version
28.0.50, [...]"
Or we could decide that the version information is not really needed
at all for the purposes of this screen.  I don't have a very strong
opinion here except that I don't think it's ideal to advertise details
like the cairo version at the very top of the screen (as before).

I thought there was some kind of legal reason that "NO WARRANTY" is on
that screen?  If it's not, we might as well move it out of the way, I
agree.

The "Ordering Manuals" could indeed get more prominence in "(emacs)
Top" instead.

We could have four items in each column, if necessary.  Somehow humans
like it when there are only three things though - it's a general
principle in graphical design.  It "feels" better to most people for
some unknown reason.  Content obviously trumps that, but I propose we
also keep that (secondary) aspect in mind.

Indeed.  I filed a feature request for a new max width option:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40909

The images are also rendered to be very small, so maybe it would be
good to file a feature request for that.

Yes, I thought that's what I did but I must have messed something up

think we should keep that.  Thanks for catching that mistake.

"Open a File", "Open Home Directory", "Customize Startup".

And if there are auto-save files, we currently show a hint to type
"M-x recover-session RET".  Is that also gone?

I can't remember the official name for such a thing (it's related to
"zeugma" which I learned about in the incomparable "dictionnaire superflu

reading), but you could call it a "type error": you join with `&`

According to rules of the Writers Guild of America West
the word “and” located between writers' names in a writing

Two things.

First: the first two items duplicate the toolbar items, so they're 
pretty unnecessary. "Customize Startup" could move somewhere else, but 
honestly, it also looks out of place, since the only apparent purpose it 
has is tell the user how to hide the start screen.

I think we better make the start screen better (like other editors do), 
so the users won't hurry to hide it right away. But keep the user 
option, of course.

> And if there are auto-save files, we currently show a hint to type

I don't know, but we could keep it.

Second thing: I think Stefan's work is a modification of the "About" 
buffer. Whereas you are talking about the startup screen. They are close 
enough to mistake one for another, but still different. For some reason.

To Stefan: to display the latter, I run 'HOME=/tmp src/emacs'.

I've noticed over the years that respondents tend to give simple (thus
not very useful) answers and that it is necessary to urge them to
explain more.

Just now it struck me that the word "poll" might suggest to
respondents that the answer requested is simply "How much do you like
or dislike this", with 5 or 7 possible answers from "Hate it" to "Love
it."  Does this seem likely?  Should we call it something else?  We
could describe it as a "study" or "investigation" instead of a "poll".

I don't have a particular preference. This string could be useful (I 
don't know). But the way it's displayed, and its length, leave something 
to be desired.

Maybe Richard has an opinion on this, but (though IANAL) I don't think 
so, considering most software (libre or not) don't make this much of an 
effort to tell the user about the lack of warranty.

If the "no warranty" thing is required there after all, we could do the 
four-row thing as the first improved version, get it installed, and then 
discuss further tweaks.

Because I'm guessing hiding the "Ordering Manuals" farther from sight 
can be seen as unfortunate (however much income it results in, IDK).

Personally, I'd prefer if it just used the web browser installed in the 
system. But I'll take any improvement over the current state.

I'd be happy to link to the poll at the top of Emacs News for several

Polls can have different forms and shapes.

But, of course, most people will find it easier to choose from one of 
the options rather than elaborate in text. Especially when they think 
the answer should be obvious to everybody.

Some of the links Stefan did keep are also such duplicates.  Any

The Subject says "welcome screen", and you yourself use "startup
screen".  So I thought this is what we were talking about.

If you ask me, the About display is much less important than the
startup/welcome/splash screen.  I very much doubt newbies look at the
About display; they almost always look at the startup screen at least
once.

If we are talking about the "About" screen (not the startup screen, as
I initially assumed), then I think the version should be there: I'm
yet to see a program which did NOT show its version in the About menu
item.  That's where people will look for it.  It might even be the
main reason people even look at the About screen.

My intention was to modify the welcome screen, yes.  I ended up
modifying the about screen (display-about-screen) only because I
mistakenly believed they were the same.  (They are very similar, to be
sure.  But there are some differences.)

Please consider my draft as a suggestion for a new welcome screen
(display-startup-screen).

Once we have a better understanding of what should be done there, I'll
be happy to suggest similar improvements to the about screen.

Same here. For testing purposes, I often run several Emacs versions in
parallel. "C-h a" is indispensable then.

OK, so let's keep the detailed version information on the about
screen.  It clearly makes sense to have it there.

I have not yet seen anyone express the opinion that it's important to
keep the detailed version information on the welcome screen.  Maybe
it's enough to show the major and minor version there.

I'm not sure which ones you mean. The rest are _also_ duplicated in the 
menu bar, but only the two of the removed ones are present on the toolbar.

In any case, the justification is that the result looks better. And we 
can get away with that because these buttons are not essential.

I would suggest interested parties take a look at the "dashboard" package
for emacs; it seems to be quite popular amongst those "starter kits" that
were discussed earlier, and has iterated around the sort of features we're
talking about here. To be clear, I'm not suggesting that we just integrate
it wholesale, although if people are interested, I'd be willing to try to
ask the author(s) about doing so. More details can be found here:

  https://github.com/emacs-dashboard/emacs-dashboard

If anyone would like, I would be willing to send them a copy of the
information from that page, so they can avoid the github burden; just let
me know.

Looks good, but it's a dashboard for day-to-day use (showing recent 
files, projects, maybe bookmarks, org agenda...), and we're currently 
discussing the start screen for the first time user.

After we're happy with it, we can talk about whether to modify it to 
show extra items, or to show an altogether different dashboard later 
(probably inspired by the above project).

"Themes" shipping configuration - an unusual convention

So a theme can be used to change configuration, and indeed this is the
recommended way to do it.  Interesting, and news to me.  But is this a
good convention?  I'm not so sure.

AFAIK, all other applications I have used understand "theme" to mean a
"package containing graphical appearance details".  This definition
from Wikipedia: https://en.wikipedia.org/wiki/Theme_(computing)

I don't think users will expect a "theme" to modify the behavior of
Emacs.  There are usually things called "profiles" where one would
save or load settings from.  This means that if M-x load-theme changes
the behavior of Emacs (significantly or otherwise), they are in for a
surprise.

I would propose to change the convention such that a "theme" is only
meant to modify "graphical appearance details".   Not behavior.  (From
what I can tell, all themes currently shipped with Emacs follow this
convention.[1])

We could introduce a *separate* convention, called e.g. "custom
profiles", which are understood to also change settings.  They could
have their own directory in our tree called "etc/profiles", and
separate commands to load them (say, M-x load-profile).

Of course, a "custom profile" could technically do anything a "theme"
does and vice versa.  Just as a 'require'd package can technically
override any face, enable viper-mode or whatever.  But we should
discourage that.

Best regards,
Stefan Kangas

PS. If anyone can point to an example of a "custom theme" that ships
settings, it would be interesting to see it.

Footnotes:
1. The exception is some variables related to graphical display, which
is not unusual or surprising to my mind.

A custom-theme is a set of custom settings, yes.

Yes, but at the same time, it's hard to draw the line: if a theme
controls the shape of menus (e.g. chooses between scroll-down menus and
pie-menus), is it "graphical appareance"?
What about the structure of a menu?  What about the place where
completions are displayed (a popup child frame vs the *Completions*
buffer)?

In any case, I'm not sure we want to start adding an artificial barrier:
the underlying technique conflates the two and I don't think it's
a problem, even if it doesn't correspond to what some other applications
offer (FWIW, I believe some application's themes are also able to change
pretty much any aspect of the behavior.  IIRC that's the case for
Enlightenment, for example).

It wouldn't be the first time that Emacs goes beyond users expectations ;-)

I'm fine with using a different naming convention for the actual
behavior-oriented themes, but I see no need to hide the fact that the
implementation is the same.

I believe this is a principal difference between
custom themes and color themes.

Custom themes are essentially part of Customize,
and from the outset they were about customizing
options.  Only later were they extended to do
some (most) of what color themes do: define a
color scheme by setting a bunch of faces, frame
parameters etc.

(That's my recollection anyway.  Chong Yidong
extended custom themes to implement some of
what color themes provide.)

Nowadays, the distinction has mostly been lost,
unfortunately, and many people speak of "color
themes" when they really mean vanilla Emacs
custom themes.

https://www.emacswiki.org/emacs/ColorThemes

https://www.emacswiki.org/emacs/CustomThemes

Your proposal seems to be to more or less limit
Emacs custom themes to defining color schemes,
or perhaps color schemes plus some other display
properties.

I was hoping we could get it into emacs-27, though. Probably a more 
expanded version too (I should look over several other toolbars).

In the meantime, could you look into the problem of the "legacy" toolbar 
being used on full-color devices? The variable gmm-tool-bar-style, 
breakage in commit d88118db37dd543536677d7c4212a2c67621fb88. I can 
create a bug report, if you like.

I don't think we should change look-and-feel during a pretest, sorry.
These are sensitive issues that tend to trigger emotions, so we should
let them live on master for some time before we release them.

Oh, it's this bit?

 (defcustom gmm-tool-bar-style
   (if (and (boundp 'tool-bar-mode)
           tool-bar-mode
-          (and (fboundp 'display-visual-class)

-                          (list 'static-gray 'gray-scale

+                      'static-color 'pseudo-color)))
       'gnome
     'retro)

Oops.  Looks like I removed the `not' by mistake while I was cleaning up
the foundp test somehow?

That's clearly a regression and should be fixed on the emacs-27 branch,
I think.

Yup.

This breakage is from 2016, so it most likely got into Emacs 25.

More importantly, while I'm all for fixing bugs, I think fixing it now 
will be more risky than my icons patch, because gmm-tool-bar-style 
affects which toolbar is shown. And for message-mode, at least, the 
'gnome' and 'retro' toolbars have different contents.

Pardon me for insistence, but I've filed bug#40990.

Perhaps we could see if there's any negative feedback at all?

Thanks, I replied there.

I'd like to avoid waiting for feedback on this, so that Emacs 27.1
could be released sooner rather than later.

Re: Log out hanging after X-forwarded emacsclient

I spent last night tracking this down. The reason one has to press ^C to
stop ssh is that Emacs keeps the X-connection open. It is not a bug in
ssh, as far as I can tell.

This comment in src/xterm.c is no longer accurate:

  13402  /* This function is called when the last frame on a display is deleted. */
  13403  void
  13404  x_delete_terminal (struct terminal *terminal)
  13405  {

It doesn't get called when the last frame on a remote display is closed,
it is only called when the X connection is severed (i.e. by killing
ssh).

The reason is found in src/frame.c:

  2141      /* If needed, delete the terminal that this frame was on.
  2142         (This must be done after the frame is killed.)  */
  2143      terminal->reference_count--;
  2144  #if defined (USE_X_TOOLKIT) || defined (USE_GTK)
  2145      /* FIXME: Deleting the terminal crashes emacs because of a GTK
  2146         bug.
  2147         https://lists.gnu.org/r/emacs-devel/2011-10/msg00363.html */
  2148
  2149      /* Since a similar behavior was observed on the Lucid and Motif
  2150         builds (see Bug#5802, Bug#21509, Bug#23499, Bug#27816), we now
  2151         don't delete the terminal for these builds either.  */
  2152      if (terminal->reference_count == 0 && terminal->type == output_x_window)
  2153        terminal->reference_count = 1;
  2154  #endif /* USE_X_TOOLKIT || USE_GTK */

With this Emacs doesn't actually call x_delete_terminal() when the last
frame on a display is closed, but rather waits until the X connection
disappears.

If I remove those two lines, a build with GTK crashes immediately when
the last frame on a remove display is closed (on purpose, to avoid the
endless warnings from Glib - "the GTK bug"), rather than when the X
connection is cut.

However, I can't reproduce the problem when I build Emacs with Lucid.
Closing all frames on a remote display doesn't result in a crash with
Lucid - and the prompt/ssh isn't hanging with L2152-2153 removed.

So a step towards fixing the GTK problem is to figure out whether the
"workaround" in src/frame.c is still needed for Lucid and Motif.

Ah, I've now read through the bugs referenced in the comment, and it
sounds like the problem that was handled by adding this doesn't happen
every time. When x_delete_terminal() gets called much less, the
described crashes are less likely to happen.

I guess it could be #ifdef'ed again, if the GTK problem is fixed.

Hm, ok. I just thought I would follow up on my question.

It seems that the author has assigned copyright for some art to FSF in

It looks nice, but he could have add a link to reference card too (under
Quick help maybe). Maybe less text, skipp the info about Lisp for

Thanks for pointing this out.

This is very nice indeed.  It's a bit of a different direction, but I
like some of the main ideas a lot.

That's a very good idea.  I will contact him in private to see if he
wants to sign the papers, or better yet collaborate with us.

It's a lot different indeed, but maybe a combination could work. Your 
version improved usability while keeping (or even improving) information 
density.

This new one is pretty, but with lower density, and much too long for 
the startup screen.

Why not.

I don't have that font installed, though, and it's still a beauty with 
"Ubuntu Mono". Just some positioning is a little bit off (the first page 
ends a tiny bit earlier than expected). Either way, we should try to 
make the startup screen work okay with the default system monospace 
fonts too.

Sorry to be a party pooper, but the build information is missing. For

Nice job. This bug affects a lot of emacs users. on 2016 I digged a
little bit on this bug aka "long-standing GTK bug". I still have my
notes from 2016. I even sketched a plan (I have never fullfilled):

Those were my conclusions from 2016:
--8<---------------cut here---------------start------------->8---
compile same source code for lucid, gtk, and nextstep
remove the abort calls {after checking all bug reports}
repeat that old gtk bug on gtk and nexstep {question is nextstep is immune as lucid}
research how was included the lucid port {get the git hash; why gtk is different from lucid}
the mac port could be useful? {macport suffers the same issue as gtk when used with x-forwarding}
--8<---------------cut here---------------end--------------->8---

Now on 2020. I would add to that list retest all cases found on frame.c
according to your email.

I could not figure out why x_terminal_close() wasn't called when the
last frame on a display was closed, and that lead me to frame.c.

Took me a couple of evenings of adding a _lot_ of print-statements and
experimenting.

My original goal was to look into "the GTK bug", and this "^C
hanging"/X-connection not being closed fell out of it as a bonus.

I don't know that any of those bugs are resolved, but I think the
workaround was acknowledged to be just a workaround when it was added,
so if the problems with the scrollbars can be solved, I think the
workaround can be removed for Lucid/Motif builds.

While related, this is not "the GTK bug", nor does it resolve it.

If you remove the workaround in frame.c and remove the call to
emacs_abort() when using GTK in x_connection_closed() in xterm.c, and
the connection to a display is terminated while Emacs has a window on
that display, you'll still get an endless stream of warnings from GLib,
i.e. "the GTK bug".

I've tried updating the latest issue on this in the GTK GitLab, to see
if anyone has some clues:

 · https://gitlab.gnome.org/GNOME/gtk/-/issues/2315#note_795365

I haven't heard anything yet, and I would not be surprised if they still
are cross with the Emacs community.

Thanks for replying, I agree it would be really nice to get to the
bottom of this long standing issue.

FWIW, I wrote up a bug report to the `better-defaults' package asking to
please keep them enabled:

I believe this blanket advice to disable the menu and tool bar should be

It looks basically good to me, but there are a few important detail

It needsto link to the non-warranty statement and the copying

It must not link to Stack Exchange, because we know it will give
advice to use nonfree software.  Also, Stack Exchange pages contain
nonfree Javascript.  I don't know what they use it for -- I was able
to browse questions and answers with LibreJS -- but they must use it

I agree.

But I agree much more strongly wrt menu-bar.

Wrt the Emacs tool-bar, I think (so far) it's
mainly useful for one-off actions (e.g. click
a button to do something - no subsequent
tool-bar interaction).

That is, I'm not sure how often a tool-bar
user clicks tool-bar buttons/icons.  I kinda
doubt that someone does click-click-click on
icons.  I think it's more likely that a user
uses a particular icon fairly often, as a
shortcut to using a menu, than it is that a
user interacts frequently with multiple icons
on the tool-bar.  (I could be wrong.)

As a result of this assumption, I provide
library `tool-bar+.el', which lets you hide
the tool-bar, replacing it by just one menu-bar
pseudo-menu, `Buttons'.  Clicking that pops
up the tool-bar for the duration of one
interaction.  This is available using minor
mode `tool-bar-pop-up-mode'.

https://www.emacswiki.org/emacs/ToolBar#ToolBarPlus

(The same library offers an alternative,
minor mode `tool-bar-here-mode', which is the
same as the global `tool-bar-mode' except that
it affects only the current frame -- it saves
screen real estate on frames other than those
with a tool-bar.)

I think it would make sense for Emacs default
behavior to be similar to that you get by
turning on `tool-bar-pop-up-mode'.  Users would
soon enough discover `Buttons'.

One useful thing that could be added and might
be useful, which I haven't done, would be to
provide a button in every tool-bar, which
toggles the mode, e.g., turns it off, so the
tool-bar is shown by default, or turns it on,
so it is hidden by default and replaced by
pseudo-menu `Buttons'.

I haven't written any novels in it, but yeah, org-mode fills my text

Yes it's probably sufficient to know the commands and let the text flow
the way it likes.

(I.e. pretty much the way AUCTeX works. I know people back in the 80-ies
and 90-ies who needed to write LaTeX and became emacs users solely
becaause of AUCTeX)

what goes on, and in navigating)

Re: long-standing GTK bug

I have been looking further into it, and I think I now understand what
happens.

Emacs calls gtk_events_pending(), which then continues to
g_main_context_prepare(), in which a counter in the context structure,
in_check_or_prepare, is incremented to detect recursive calls to this
function in GLib.

Before the counter is decremented again, the X-connection disappears,
and X calls Emacs' error handler x_io_error_quitter().

The error handler closes the display¹, and Emacs then continues. But it
doesn't return to the place in g_main_context_prepare(), so the counter
isn't decremented.

When Emacs then calls gtk_events_pending() again, GLib looks at the
counter, and emits warnings about recursive calls.

At least that is what I think is happening - gleaned from adding a
breakpoint to delete_frame() and staring at this backtrace and the code
in GLib²:

  #0  delete_frame (frame=0x555556183ba5, force=force@entry=0xa170) at frame.c:1902
  #1  0x000055555559707e in x_connection_closed (dpy=dpy@entry=0x555556c58590, error_message=<optimized out>,

  #11 0x000055555564c97d in XTread_socket (terminal=<optimized out>, hold_quit=0x7fffffffd200) at xterm.c:9398

To test my interpretation, I decided to decrement the counter in the
context structure from inside x_connection_closed(), by adding:

        GMainContext *context;
        context = g_main_context_default();
        // Try resetting recursion prevention counter:
        context->in_check_or_prepare = 0;

before calling gdk_display_close() on the display that has disappeared³.

This makes the endless stream of warnings not appear!

However, my quick test required me to copy the struct _GMainContext
definition from glib/gmain.c into xterm.c, which is not the correct way
to go about this, I'm sure.

I do feel that this is progress, though. Now we just need to figure out
the right way to handle it.

If that is for gdk_display_close() to reset the in_check_or_prepare
counter, or if it is something that can be changed in Emacs, I don't
know.

I have updated the current GTK issue⁴ with my observations, but I'm
hoping for some input from emacs-devel as well.

    Adam

When I write a pamphlet using Libre Office, I need to see how it
will appear on the page.  I need to see where line breaks and paragraph
breaks appear.

I want Emacs to be able to do tect processing that way.

When you say page, you mean a printed page on paper?

Can't that be helped with some of live preview options for a pdf or ps
or latex format? Auctex maybe? Or maybe some of org -> pdf/ps + DocView?

Or couldn't it be possible to define some html+css to model A4 paper
size, for example:

https://codepen.io/rafaelcastrocouto/pen/LFAes

and use some of live preview options for html (eww or browseurl or
something else)? Not a wysiwyg directly, but kind-of middle ground?

Maybe chromium-browser --print-to-pdf=doc.pdf --headless --disable-gpu
      --run-all-compositor-stages-before-draw --no-margins doc.html
or using its wrapper chromehtml2pdf.

Of course.  A pamphlet is for handing out.

It would probably take half a minute each time.  I am sure you
understand the advantage of WYSIWYG.  Especially when the text needs
to fit in a limited space.

This is not an issue for longer documents, since it doesn't crucially matter
where the page breaks are in those.

I think you made a typo here, it should have been "half a second"

I understand that wysiwyg is easier and I understand your concern
for delays. I believe those delays would not be noticable for a pamphlet
(A4/A5 size?) if you used html as intermediate format.

Anyway what about if emacs had a print-page-mode as a minor mode for
displaying some printing hints in text modes? I am not sure if I can
write such, but here is idea:

* provide a database of predefined paper sizes as specified on:
  https://www.papersizes.org/a-sizes-in-pixels.htm
  to be used as templates for width and height (in pixels)
  
* advice insert funcion(s) to check for current line pixel-width and
  pixel-height. If width or height exceed template width and height then
  insert ^L to denote page break and move point to next line and insert
  text in next line. If width is exceeded maybe it is just enough to
  move point to next line, but when height for a page is exceeded one
  would need a special char to visualize page break.

As I understand Emacs already has some support for page breaks (^L) as I
learned myself very recently :-). There is extended page handling in
Emacs and also a mode called PageMode:

https://www.emacswiki.org/emacs/PageMode

I am not sure, but what I think is missing is just to tie those things
to paper sizes and automize page creation based on some paper template
which is nothing but a pixel-width and pixel-height. I am not sure, I
haven't used PageMode myself, I just learned about it.

I am not sure how efficient it would be to check for pixel-width and height
on every char insertion, maybe there is some better way?

It would be nice if Emacs could draw a thin line to denote edges, or a
rectangle of page size below the text as word processors do, but that
would ask for some c and exposing of some graphics (XDrawRect & co) to
elisp?

All of this is already available, although not all of it is exposed to
Lisp.  Taking advantage of existing pixel-level capabilities is part
of the job of providing the features that Richard has in mind.

We already can display such thin lines, see, for example, help-fns.el
(search for ":height").  No X-level graphics is needed.

When you say all of this, and not exposed to lisp, what exactly do you
mean? :-) Is it possible to get a pixel offset from a point with elisp?
Height, width, or whatever that could be used to calculate if current
buffer region fits iin a page or not?

(defvar ppi-72
  '((4A0 . (4768 . 6741))
    (2A0 . (3370 . 4768))
    (A0  . (2384 . 3370))
    (A1  . (1684 . 2384))
    (A2  . (1191 . 1684))
    (A3  . (842  . 1191))
    (A4  . (595  . 842 ))
    (A5  . (420  . 595 ))
    (A6  . (298  . 420 ))
    (A7  . (210  . 298 ))
    (A8  . (147  . 210 ))
    (A9  . (105  . 147 ))
    (A10 . (74   . 105 ))))

If I have a database of sizes like this, I would need to know a size in
pixel of a buffer region between some min and max points. That could be
used to either defadvice insert or to calculate and restructure text
afterwards. Maybe it is to naive, no idea, just thinking. Also I am not
sure how resolution/ppi relate to emacs buffers to be honest.

As composed of characters or as overlays with underline/overstruck or
similar? What about a rectangle in some color as a background to
symbolize a page. I understand it is not needed, but it would be nice.

See window-text-pixel-size as one example of what we have.  The
underlying functionality is even more powerful.

Just look at the code, it is self-explanatory, IMO.

You will see in the code I pointed to that we actually already produce
a rectangle, just a very thin one.

Just as a point of interest: page breaks definitely can matter
in longer documents. I've done quite a number of books with
Emacs/LaTeX, and in doing text layout I have to take into
account widows and orphans--- for instance, having a single
line of a paragraph at the bottom of a page is a no-no, and
page breaks have to be manipulated to avoid bad typography.

That said, I've found that even for longish books with many
diagrams (my most extreme example was nearly 800 pages), the
compile and view process was fast enough not to get in the
way, and corrections and changes go very fast if using
something like synctex (I believe that's the correct name).

This is not to say that I don't see the need for WYSIWYG on
graphics-intense publications; for instance I couldn't see
doing a comic book in emacs.

there are alternatives which don't require malware:

   abiword --to=PDF -o a.pdf a.html
   soffice --headless --convert-to pdf a.html
   wkhtmltopdf -B 24 -L 24 -R 24 -T 24 a.html a.pdf

But none of those produce good documents.

As an experiment, I tried to produce the ebooks.pdf document from
org-mode, exported to html, opened in firefox, printed to pdf.  It gave
the best result.  It looked almost like the original and was easy to
tune in org-mode.  I only had to iterate a few times.

But still, all these solutions require huge dependencies.

It does?  Can you show an example?  Or, better yet, make a bug report

You need a GUI frame (not necessarily on X), but that's all.  There's
no need to expose Xlib calls to Lisp, which was what the original
question was about.

What are the missing pieces?

I think there are many and they would be useful for other use-cases.

Some of the use-cases I am interested in:

1) Sometimes, I need to write a letter which does not need to be an art
   work.  I wrote emacs-pdf (see
   <https://logand.com/sw/emacs-pdf/file/emacs-pdf.el.html>) to address
   that.

   It creates a PDF document from an Emacs buffer.  Only plain,
   monospace ASCII text works so far, but it can already break and count
   pages and insert headers and footers.  It is very short (about 400
   lines of elisp including comments) and requires no dependencies and
   no graphics.

   a) The next step will be unicode.

      It seems that there is some code in Emacs dealing with unicode
      fonts in order to generate postscript files.  Any pointers where
      to start with this?
  
   b) After that, emacs-pdf will understand font metrics so it will be
      possible to do layout.

      It should be possible to render HTML for example, and create
      graphical web browser as an alternative to eww.

      It should also be possible to render other formats like abw, odt,
      etc.  At least roughly, depending on how much detail in the
      corresponding spec people want to address.  I have explored simple
      conversion to text in pure elisp in emacs-unoffice
      <https://logand.com/sw/emacs-unoffice/file/emacs-unoffice.el.html>.

      It should be possible to write a direct PDF backend for org-mode
      and maybe enriched-mode.

      Internally, probably some kind of html like sexp based format
      should be used.  I used a sexp based format in emacs-pdf
      (transient cons tree representation) but for document processing,
      the format should not be so low level (e.g. no PDF drawing
      primitives but something like HTML primitives; or maybe mixed).

   c) It should not be difficult to add raster images and vector
      graphics to the PDF drawing code.

   d) It should be possible to add for example SVG backend.  Non-console
      Emacs can already draw SVG.  At least at the beginning, this would
      also avoid the need for image rasterisation if vector format like
      PDF or SVG is used.

      Maybe this could be used for real-time preview, before we get
      WYSIWYG.  Or maybe use pdf-tools to view the generated PDF.

2) Printing is an issue in Emacs.  I will try to implement an
   alternative which will use IPP and PDF.  No PostScript, no CUPS, if
   possible no complex configuration.

3) I use Emacs on the console a lot.  All the above should work there
   too.  In order to view images in console Emacs, I wrote
   <https://logand.com/sw/emacs-framebuffer/file/emacs-framebuffer.el.html>.
   So far there are a few functions that draw images using w3mimgdisplay
   from the w3m console web browser.  It fits images on the screen,
   unlike graphical Emacs where image display is unuseable.

   a) I would like image-mode just work with this emacs-framebuffer
      image drawing.  Any ideas, how to plug emacs-framebuffer into
      image-mode?

   b) It is a shame, that I need to reimplement such basic functions
      like image-size:

      (image-size (create-image "/tmp/a.jpg"))
      => (error "Window system frame should be used")

      framebuffer-image-size at
      https://logand.com/sw/emacs-framebuffer/file/emacs-framebuffer.el.html#l95
      does not require any dependencies and computes image size for png,
      jpeg, bmp, gif, tiff and pnm in elisp.

      It would be nice to eliminate or at least reduce the need for such
      dependencies so that many Emacs features are useable in different
      environments, like for example console.

   c) There are functions frame-width and frame-height.  Are there also
      functions something like buffer-width and buffer-height and or a
      way to compute x and y position relative to frame origin, which
      would allow me to position images exactly in the buffer similar to
      what w3m browser does?

4) Emacs is missing some kind of canvas, where things could be drawn and
   which would handle pixel precise input.

   For example, I would like to browse OpenStreetMap in Emacs.  I wrote
   a console based OSM browser osmq
   <https://logand.com/sw/osmq/log.html> and web-based OSM browser at
   <https://osmq.eu/>.  I would prefer an Emacs based map browser.
   However, I have not figured out how to lay out images in Emacs in a
   grid and how to detect which image was clicked.  A bonus would be,
   where exactly was clicked.  Any ideas what should I look into?

   Emacs canvas should probably work like HTML canvas, which is rather
   similar to PDF or PostScript in terms of drawing interface.  I have
   explored this space in the PostScript interpreter in JavaScript
   <https://logand.com/sw/wps/index.html>.

   Not sure how difficult it would be to plug some kind of portable
   canvas into Emacs.  This seems rather low level C work.

It seems to me that these points are precondition for a WYSIWYG document
editor feature in Emacs.

Do these points resonate here?

Is somebody already implementing anything mentioned?

Or what is already implemented?

Would there be an interest in incorporating emacs-pdf, emacs-unoffice
and emacs-framebuffer (the framebuffer-image-size function?) into Emacs?

Regards,

Tomas

If this works reliably, and isn't very slow, it could be good enough.
For this to work reliably requires understanding the width of text
as it will eventually be rendered, including different sizes and
variants (italic, bold, etc).

We can arrange to take note of how wide the line is,
update that incrementally in a quick way, then do more
processing when that seems necessary.

Better exporting of Emacs buffers to PDF is certainly a desirable feature.
Any system for editing formatted text in Emacs will need that feature.

I think you should provide more details about the particular problem
you are trying to solve here, because I don't think I understand it.
Emacs generally knows only about fonts it uses for its own display,
and it needs to load the font before it can provide information about
it.  Whereas you seem to be talking about fonts to be used in the PDF
file, not in Emacs display.

>    b) After that, emacs-pdf will understand font metrics so it will be

I very much doubt you can do sensible layout in Lisp.  shr.el tries,
but the result is slow and incomplete -- and it does that with text
displayed by Emacs itself, whereas you are talking about something
more ambitious.

If you want to do layout for PDF, I think one way forward would be to
implement a pdfterm.c "terminal" for Emacs, which produces PDF like
the existing *term.c backends do for supported display types.

Yes, there are, but they need a window to compute these metrics.
Without a live window, "buffer width" is meaningless, because buffer
text doesn't define the fonts (more generally, the typefaces) used for
displaying the text.  Only a window in which a buffer is displayed
provides enough typeface information to do these calculations.

Emacs supports "hot spots" on images for this: a click on an image
returns information about pixel-resolution offset of the click from
the image origin.  I think that's what you want, although I'm not 100%
sure.

We also support displaying slices of images, in case that helps to
produce a smarter layout of images.

> It seems to me that these points are precondition for a WYSIWYG document

FWIW, I don't think these points are necessarily preconditions for
WYSIWYG features.  They are important and useful features, but a
WYSIWYG document editor should IMO start with something whose
beginning we have in enriched-mode.  That mode currently lacks the
ability of laying out text in variable-pitch typefaces, which I think
is the first extension of enriched-mode that should be worked on.
Followed by page layout and page breaks, intelligent sectioning
commands, etc. etc.  And yes, printing is also important, whether it
is done by producing PDF or PostScript or any other intermediate
format.

FWIW, I don't think this is possible from Lisp, not with the currently
available facilities.  shr.el does something like that, and it does a
decent job with the tools it has, but IMO it is nowhere near what is
needed, and cannot handle complex situations with various complex
scripts.  It is also quite slow: I sometimes need to wait for several
seconds for it to display an email message of a couple of hundreds
lines.

Layout in Emacs has to be done in C to be both efficient and fully
capable.  Some small and simple jobs, like pixel-level alignment, can
be done in Lisp, but not the entire job as a whole.

I don't know what kind of computer you use, of course, but if you ment
the startup time for a browser, then maybe it is a half second or so, but
does it matter? It happends once, when one start to work on a pamflet.
LibreOffice takes also a half a second if not more to startup every time
and I have quite decent machine.

If you start a Chromium process, and then connect from within Emacs with
impatient-mode, I don't think you would suffer from lack of real time
performance; not for something like a pamflet.

Another option is to use some webkit wrap + xwidgets, but I haven't
tryed it myself. No idea how easy to use or good it is, but for preview
it should probably be good enough. I have seen some Reddit threads
and YT videos where people demonstrated it, but I didn't care to try
myself.

Here is some 4 year old video where a guy is demonstrating xwidgets and
webkit to render html in gnus:

https://www.youtube.com/watch?v=J2YdjpWJJHs

(download with youtube-dl to skip proprietary js)

Very nice presentation by the way.

With HTML+CSS as intermediate file format, one can have some predefined
templates with a pamflet size, layout, typografi etc, and then just edit
content of few html tags.

The process that was suggested for viewing the page image
involved running several programs each time.  A few seconds to start each
and it could take half a minute.

I use a machine that was made in 2008 or so.  I use it because we can
boot it with libreboot.  I cannot predict when there might be a faster
machine I could use.

I poked around a bit and it seems that what I did in emacs-pdf
(pdf-buffer function) is similar to what ps-print-buffer function does
in ps-print and ps-mule with ps-multibyte-buffer set to nil.

Now I want something like ps-multibyte-buffer, e.g. pdf-multibyte-buffer
so that I can use non-ASCII characters in the generated PDF.  So I
probably want to implement something similar to ps-multibyte-buffer
cases of non-latin-printer, bdf-font and/or bdf-font-except-latin.

There seem to be ps-bdf so maybe I have to look, if I can reuse
something when generating PDF.

I see.

There is frame-position but no window-position.  Is there a way to get
window position in a frame?

Interesting.  Maybe the pdfterm.c you suggested is kind of canvas I
wrote about.  When there is all that complexity with pixel perfect
drawing and layout, it would be shame to limit it to enriched mode.  But
it is still too early to make decisions in this direction.

Or is it, huh.[^1] For some reason, the FAQ on the main site[^2] has
the question “Is Brave free?”, and the answer only talks about
free-as-in-beer. To find out about the free-as-in-freedom aspect, you
have to notice the Github link in the footer.

BDF fonts were OK when ps-mule.el and ps-bdf.el were developed, but
nowadays I think you will find that many users will object to using
bitmapped fonts in printed matter.  (There were plans to develop
ps-type1.el, but I don't think they materialized.)  Caveat emptor.

I suggest to read "Click Events" and "Accessing Mouse" in the ELisp
manual, I think the description there is clear enough to let you write
code even without examples.

Likewise here: I suggest to read "Showing Images", where this is
described.

I understand.

Have you heard about company called Purism and librem project?

https://puri.sm/why-purism/

I am not sure if it is suitable enough, but they do run only free
software, from boot (coreboot) to highest level; at least as I understand
them. Also I believe they went to the length of ordering Intel cpus with
intel's "management" backdoor disabled. Just as a tip.

Thanks for that link.  Interesting discussion.
I'm no expert on these things, but this remark
there seems relevant:

  "Brave ads are opt-in, for people who would like
   to earn "shitty" cryptocurrency by clicking on them."

I opted out, at the outset.  Perhaps I'm not aware
of some other behind-the-scenes behavior that's
problematic.  I didn't read all of the page you
link to in detail, but my (maybe naive) impression
is that if you opt out of ads that pretty much
takes care of things.

The only technical problem I've encountered with
Brave, compared to Google Chrome, is that some
dropdown/pulldown lists on some sites don't work.

I know nothing about Brave, but I'm wondering instead why it is that

Can't it just run "the" browser, whichever it is?

Yes, window-edges is what I was looking for, thanks.  Now I can draw
images in console exactly where they should be.

However, there seem to be problem with get-buffer-window function:

get-buffer-window returns one buffer or nil.  This seems wrong because a
buffer can be visible on many windows.

Is there a function (or trick) which returns all windows, where a
specified buffer is visible?

There is a lot of cruft accumulated in browse-url.el mostly for old browsers
with different handling of command line arguments for "new-window-is-tab" logic.
But it seems nowadays only three options should be sufficient:

- use the default browser found by browse-url-default-browser;
- or use Emacs browser eww;
- or allow to specify a browser program name with additional arguments.

ISTR that Brave _is_ free software, but has a malfeature.
So we would not want to propose its use.

I've been misinformed about this before -- we would want someone
to check carefully.

Someone could make a modified version without that.  Does this exist?

We certainly should have a pdf-print-buffer.
One way would be to call ps-print-buffer
and then run ps2pdf.

Ideally the GTK developers would fix this.  Apparently a long time has

AFAIU, they concluded that Emacs doesn't use GTK as a well-behaving
GTK application should, and so they decided not to fix this problem.

Did they say how a well-behaved program would do this job?

Tab-bar autoclose question

[Ergus]

[-- Attachment #1: Type: text/plain, Size: 260 bytes --]

Hi Juri:

I am wondering if maybe there is a simple method to autohide/autoclose the tabbar in some condition. For example, when I close all the other tabs and there is only one.
Is it a straightforward/out_of_the_box method to customize that?

I believe that should be quite clear to someone who is familiar with
how GTK applications should be written.  (I'm not one of those
experts.)

I think someone is working on an Emacs configuration that will support
only GTK, and that configuration should then be able to do that.

Please try to customize ‘tab-bar-show’ to the value ‘1’
that means to hide the tab-bar when it has only one tab.

Hello! As someone who does not contribute to Emacs for the sole reason
it is *way* harder than in any other project I'm aware of (although
well in line with other GNU projects, but even among them Emacs takes
the lead) I want to emphasize this is not a "shallow reason".

It all comes down to Emacs development not being automated. Which puts
down too much strain on contributors (not mentioning Emacs maintainers
here, because last time this discussion happened (1.5 year ago I
think), Eli ensured me that they are okay. Fair enough: I'm not a Emacs
maintainer, not gonna speak for them).

1. There are many wrong ways to send a patch; and the correct one is
the most non-obvious. Most popular mistakes I think come down to copy-
pasting the patch into email client. Most modern email clients require
lots of tinkering before they work fine with plain text, otherwise
they'll screw patch up in various ways (breaking lines, replacing
whitespace, removing whitespace, you name it).
   Okay, so usually email-based projects recommend using git-send-
email. Recently I sent a patch like this¹ and got a complaint it
doesn't look like what git-format-patch would produce (is that maybe a
hint maintainers are being strained too?). Huh, wrong way again? I'll
give you some examples so you'd see the format looks exactly what other
email-based project use/used: one from Mesa project² (well, before they
moved over to Gitlab-based development) and another one from kernel³.
   What's the correct way? Well, apparently it is either to combine in
some way git-send-email and git-format-patch, or it is to attach a
patch to email. "To attach", who would've thought? Attaching patches
is frowned upon in all other email-based projects because it is hard
to review it, Idk why Emacs even allows that…
   Okay, let's get back to all those "great packages not included in
Emacs": YOU CAN NOT SEND THEM PATCH WRONG. Sorry for caps, I want to
make sure it is visible: there is no way I'll send a patch, say, to
company-mode, and will get a reply "Dude, your patch does not apply
here"! They use either (open-source btw) Gitlab or (proprietary)
Github. You can use command line or web-browser to send patches —
either way, it all becomes a thing called merge/pull request, and
making sure it is correct is all automated. Zero efforts from package
maintainers or contributors.

2. Unusual requirements from commit messages: no other projects require
writing down a list of functions I changed just for the fun of it. This
is what there diff is for! Let me guess where the requirement came
from: I remember seeing that Emacs maintainers accept even patches
with a bunch of unrelated changes, like 1.
renaming a variable, 2. refactoring a code, 3. adding a new feature. No
serious project would accept such patches, but apparently Emacs decided
to hack that around, and are instead requiring that people write
down each function name and its change in commit message.
   Okay, you want this — but could you at least automate it!
And no, some Emacs function does not cut it, people not necessarily use
git from Emacs. I
personally don't. Please, use git hoooks, because this is what everyone
is *forced* to use, you can't possibly miss a git hook. And please,
make sure that when people do git-commit-amend, the function names are
updated accordingly.
   Full automation, to make sure this unusual unique requirement of
Emacs development stays as unobtrusive as possible.

3. FSF assignment: yeah, it is easy to get. But as a package
maintainer, would I want more contributions or only having code from
elite members of FSF? I'd go for the former. If some package user found
some corner case in a function in my package and wants to contribute it
now, and I stop them "go assign some copyright and don't appear at my
project without that", this is a punch into motivation. They may do it
or not, it depends.

4. Patches are discussed on a bugtracker. Good news: contributors
probably won't care. Bad news: as a package maintainer I'd not want to
give up my abilities to 1. Close outdated discussions 2. See the diff
between current and previous patchset version 3. Immediately see which
patchset is the current version. 4. Automatically run CI on the new
uploaded version of the patchset. 5. Immediately merge the patchset
once I'm fine with the changes.

5. As a contributor, when I stumble upon a bug I could fix in
software, first thing I usually do is go check it is not fixed in
latest code and that there's no pending merge/pull requests that seem
to fix that same thing. So, for example, I want to see pending
patchsets to python-mode, can I do that with Emacs
"bug-patch-tracker"? No, with debbugs.gnu.org you can either find
pending patchsets, or you can make a text search, but over everything:
bugs, patchsets, closed or not…

P.S.: I have a feeling, people on Emacs-devel don't consider these to
be anything but nuance. Well, I've got FSF assignment for contributing
to Emacs, and since then I have many times stumbled upon things I
could try to improve. But every time it happens, I remember how hard
it is to contribute here, and dismiss myself with "no, not worth
it". The patch from two weeks ago¹ was the exception just because when
I stumbled upon that problem, I immediately figured it is likely a
one-liner fix.

As it currently stands, I'd strongly recommend against moving packages
from gitlab/github to Emacs upstream.

FTR: that wasn't a complaint, it was a gentle request for the future.
Your patch was committed, before I sent that request, even though
committing it required some extra manual work on my part.

We recommend using git-format-patch because it makes applying the
patch easier and less error prone.  It never occurred to me that a
routine recommendation would be interpreted as a "complaint", let
alone trigger a 950-word rant.

That "rant" is for a reason though? I love Emacs, and it hurts me to
see human resources are being spent in places that other projects
trivially avoid. If you multiply that effort by number of contributors
that made similar mistake and maintainers that wrote to them about it,
I think it would've resulted in time that could've been spent to do
something much more useful.

I could be wrong but to me that patch looks fine and applies here
without modification.

The only possibly unusual step I took was to save the complete email
to a file, then I applied it using git as normal.

Am I missing something here?

I didn't have an mbox file, I only had an email message which was not
in git-format-patch format, and whose commit log message needed some
work.

Anyway, I will gladly delegate the job of pushing these forgotten
patches to someone else, if they volunteer (or just do it even without
volunteering).  I only pushed this because no one else did, for more
than a week.  I thought I was doing okay by following up on those
patches.  Or am I missing something?

As a reviewer, there's something to be said about having an overview of 
the whole diff (which can get long) in a few paragraphs on top of the 
patch. A good commit message like that actually makes a lot of things 
clear in advance.

But yes, that also compensates for otherwise more difficult review 
process, compared to some automated tools other projects use.

Someday(tm) we'll migrate to Gitlab, or Gogs, or whatever, and we'll 
have that.

Regarding hooks, we do use them to an extent, but nobody has written a 
checker for commit messages for them yet. And that still wouldn't cover 
people who make patches against released/packaged versions of Emacs, as 
opposed to the Git tree.

The rest of your email, I pretty much agree with. Except, you know, it's 
still quite possible to contribute (pointing to self).

FTR, I'm really thankful to you for taking a look at the patch, as well as to all
other wonderful people here for maintaining Emacs. My text was just addressing
weak points of current development approach and is an answer to the question "why
don't people upstream their packages to Emacs". There's not much more to this
email, and the patch discussion only really mentioned in the first point by
virtue of being an illustration at hand.

No, I didn't intend to attack you, I was just curious because I would
have thought it should be easy for Emacs to take the email
(git-format-patch format is a plain email, as is the mbox format) and
pipe it straight into git am.

You don't need a file, just pipe it to git am.

Of course, that's what I usually do.  But when the email has only a
patch, not a result of git-format-patch, I don't want to try, because
some irregularity of the format could fail the patch and/or the
following commit, and I would then need to recover, fix the patch or
apply it manually, etc.  So I use "git apply" in those cases instead.
Which needs a separate commit step, including specifying the right
author and date.

And the commit log message needs a manual fix in any case.

That's what I do, always had.  But I don't even want to try when the
mail message was not formatted with git-format-patch.

FTR, I am all for having good commit messages. It is IMO a must have for any git
project. But having a list of function names with description for each does not
make one. Instead it should be an overview of what is done, why, and how.

Suppose you have a patch that deduplicates the same code pattern across 34
functions by factoring it out to a single short function. Do you really need
that list? I mean, sure it's a fun fact to know, but you'll have to review diff
anyway. If anything, it only burdens you by forcing to check that each function
is on the list. Commit message should reveal the intention of the changes (and
perhaps, if OP thinks changes may raise questions, they should also write the
reasoning). And then a reviewer gotta check (in particular) this intention
matches the actual code.

On that matter I often love to quote a post from 2009 by Peter Hutterer, a
libinput and Linux HID subsystem maintainer. A post that is old but is not
outdated http://who-t.blogspot.com/2009/12/on-commit-messages.html

FWIW, one great benefit of this list for me is that I can quickly
'git log --grep' for all commits that mention a particular definition.
Doing the same with 'git log -G' is painfully slower and with a far
lower signal:noise ratio.

That, or at the very least linking to the relevant bug/thread
discussions, is always a good thing to do and encouraged.

No, in such cases there are shortcuts you can take, such as "all callers
changed".

No, and no one will ever ask you to describe such mechanistic changes
one by one.

It's all in the GNU Coding Standards, btw.  I suggest to read that.

+1. I even use this for my own projects or projects where it's not
required. Producing that list is a last self-reviewing step that summarizes
_how_ the change was implemented. The diff itself is the ultimate source,
but a summary is it very welcome.

Of course most good commit messages don't stop there, they also explain the
_why_.

In general, Konstantin. I think your "for fun" exemplifies how you and many
others think of these procedures as spurious, or gratuitous. But they're
not, they exist because she people, whom you may disagree with, find them
useful.

You can get that purely with git by using option `-L` of gitlong. It has syntax
`-L :<funcname>:<file>`.

To give you example, I just looked at my recent change in python.el, and the
diff says the region belongs to `python-font-lock-keywords-maximum-decoration`.
So I execute:

	git log -L :python-font-lock-keywords-maximum-
decoration:lisp/progmodes/python.el

And I get a log of commits that changed that function. Git version 2.27.0

Oh, is that something new? I'm just wondering, why when I did the change to
replace hex regexes with xdigit 
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=36167 I had to write all hundreds
of functions instead of a one liner "all callers are changed"?

Oh, sure I can be mistaken. I see you replied to Dmitry's email, I had a follow-
up on it. Does my follow-up mail change your opinion, or perhaps do you have
some example in mind that a good commit message without the list would not
solve?

And what if a commit message references a particular variable or
function without touching the file that they're defined in?  I'm talking
about more general xrefing.

You didn't exactly.  It is possible to take shortcuts depending on the

I feel there's some misunderstanding. The list our discussion is about only
mentions changed functions/variables. If the git message references a variable
that is not changed just because it is important to mention, then, well, it
should still be there, in the commit message. That's what good commit messages
are for: you mention things that are important to mention ¯\_(ツ)_/¯

Oh, okay, so I read the docs, and apparently this "all callers are changed" can
only be used when you use a calling convention. In my imaginary example where
you factored out a code from 34 functions it would not be a calling convention,
it would be a piece of code inside those functions. This is actually similar to
the patch that replaces regexes to "xdigit": you have the same pattern *inside*
many functions that you replace. No calling convention changes.

It doesn't strictly have to be a change in calling convention, you can
use your better judgement.  E.g. you can list only the affected files,
and either way you only need to mention the same message once for all
affected definitions.

Having a standard that increases the likelihood of having such a 
description in the commit message without having to ask the contributor 
twice is not a bad thing.

Yes and no. If I get the purpose of the diff, I could scan the contents 
more superficially (depending on what kind of changes are proposed, and 
where).

That, too.

In any case, ChangeLog-style commit messages *are* a barrier for 
contributing, and one could argue that in the end they don't bring 
enough benefit to offset that.

But our experience shows that they do bring a certain benefit.

It's a pretty good guideline. But one that's a bit harder to check and 
enforce.

I agree, it is always great to formalize things. Okay, let's test it. Imagine a
contributor who are not aware how to write a good commit message, to see how
that guideline would help.

So, they make a non-trivial functional change ("non-trivial" because here we
don't care of trivials like "rename a thing" or "factor out the code". These can
often be described just in the commit title alone), let's say, they replaced a
"list" container in a few functions to a binary tree for whatever reason. Now
we'd like to know why did that happen.

In my case they clearly would not produce anything useful, they'll maybe write
"replace list to a binary tree" and that's it. Why? Who knows.

How will they behave in your case? Well, they'll collect the functions list,
then would scrupulously write an immensely useful information against each one
"Replace list to a binary tree here". You see, it is the same here.

Sorry if I'm misreading, but given the context of comparing commit-messages with
the list and without, I can only interpret the "yes" as "yes, one sentence that
says the code pattern is factored out from all the functions is not enough, I
need a similar sentence to be repeated 34 times". Is there other interpretation
that I do not see, or do I get it right?

This! Strictly speaking, as a reviewer you should check it. If a contributor
forgot to add or remove a function on v2 of patches, and you passed them your
Reviewed-by, wrong commit message would partially be your fault.

You do not usually check it exactly because it is trivially a burden.

We might want to know more things than that, actually.

Then I'll probably ask. If the preceding discussion, or the contents of 
the associated bug report, haven't made the reason clear already.

Let's imagine that I know that in the codebase 'list' is used in many 
places, and then in the ChangeLog entry I see that only some of them 
have been replaced.

Then I cut the review short and ask about the rest of the places.

Similarly if they actually described the reason the change, but the 
enumerated changes don't match that goal (e.g. some changes in some 
files are missing).

Another concern that can come up are whether they added 
backward-compatibility aliases (to satisfy our backward compatibility 
policy), which should also be apparent from the ChangeLog style entry. Etc.

Yes, as in "I'd have to review the diff anyway", and no, as in "I won't 
have to spend as much time doing it as I might have without the 
ChangeLog style summary".

I'm all in favor of automated checks. Someone would need to implement 
them, though.

Sure, all you say sounds reasonable. The point I'm trying to make is that you
have to ask the author for better commit message either way. IOW, you have to
ask that disregarding whether they're obliged to write down the list of
functions changed or not. So having the list didn't help here.

Admittedly, I might be the wrong person to make up an example since I didn't see
the point in this list to begin with. Better examples are certainly welcome.

Please note we're discussing whether having the list of functions changed is
worth it comparing to just the commit message. Having a good commit message is
just as enough, so you "won't have to spend as much time doing it". Like, in the
example with factoring out a code from 34 functions it's enough to just write
"Many functions use same code pattern to do X. Factor it out to a separate
function Y". What changes if instead of this one sentence you have 34 lines with
function names? Besides, as I hopefully showed in my prev. paragraph, if an
author is bad in writing commit messages, having that would hardly change
anything.

I might have read it.  I'm not saying good commit messages are
impossible without the summarizing list; I'm just saying it's a good
thing to have, something I've grown accustomed to.  When composing them,
they're a good exercise in self-review.  But of course there's more ways
to skin a cat.  This just happens to be the way we use here.

It's not "for fun".  Of course is a mental cost in composing them,
especially if you don't do it often and use the friendly C-x 4 a
shortcut.  But there is a gain, too.

In case that clears up some confusion:

As Konstantin said, the patch[1] was sent with git send-email, which
allows the sender to "annotate" the patch with some text that will be
ignored by git am (IIUC merely by virtue of being stuck between "---\n"
and the actual diff).

In Gnus, piping the whole mail to "cd path/to/emacs && git am" (hitting
"|" in the summary buffer) mostly does TRT: the patch is applied, with
the email's subject as commit summary, and the rest of the message (up
to "---\n") completing the commit message.

The only issue, AFAICT, is that git am fails to strip away the [PATCH]
prefix; IUUC this is because it does not expect debbugs's own "bug#NNN"
prefix.


Feel free to dismiss this as armchair commentary, but I think that we're
likely to see more and more patches sent with git send-email[2], since
it is heavily promoted by other projects privileging mail-based
workflows[3].

We accept and welcome patches in any form and shape.  However, we
recommend to use "git format-patch" (see CONTRIBUTE), and for a good
reason: doing so leaves no doubt regarding the authorship of the
changes.  Whereas just sending email could dupe us in attributing the
change to a different person, something that we try to avoid.  Of
course, with enough manual work and using various Git optional
switches, any problem can be worked around, for the price of more time
invested.

This is why I generally comment on patches sent in forms other than
what is described in CONTRIBUTE.  Eventually, that is our main
contribution document, and we should either stick to what it says or
change the document.

No, he did not.  He said that much: he used "git send-email".

You are hinting that "git send-email" runs format-patch internally, for some variants of its command-line arguments.  But that is not what CONTRIBUTE says about using "git send-email", and for a good reason: doing it the CONTRIBUTE way produces email messages that are easily recognizable as being fit for "git am", and don't require tedious and error-prone manual analysis to make sure it is not just diffs pasted into the email body.

We can discuss changes to CONTRIBUTE, but as long as it says something, let's try to act as it says.  We usually have good reasons for what it says.

AFAIU, git send-email literally just runs format-patch, and sends the
result (with said optional annotation) over SMTP.  I'm not sure what
difference this makes as far as authorship authenticity is concerned?
The From field used by git send-email is literally the From field set by
git format-patch.

Really, the only differences that I can see between format-patch and
send-email are

- for contributors, no need to whip out a mail client and fiddle with
  attachments,

- for maintainers, no need to scan the mail for attachments; just pipe
  the mail itself to git am.

Apologies if I'm missing anything.

Exactly, thus git format-patch.

   Exactly, thus git format-patch.

No, git send-mail accepts multiple inputs -- and it is not guaranteed
that the input is from format-patch in any shape or form.  From the
man page:

       There are two formats accepted for patch files:

        1. mbox format files

           This is what git-format-patch(1) generates. Most headers and MIME
           formatting are ignored.

        2. The original format used by Greg Kroah-Hartman's
           send_lots_of_email.pl script

           This format expects the first line of the file to contain the "Cc:"
           value and the "Subject:" of the message as the second line.

Computers do not work by osmosis; there is always input.  The input
here is either files, directories, or a rev-list.  The files and
directories can contain either git-am output, or GRH's format.  

	NAME
	       git-send-email - Send a collection of patches as emails
	
	SYNOPSIS
	       git send-email [<options>] <file|directory|rev-list options>...
	       git send-email --dump-aliases
	
	DESCRIPTION
	       Takes the patches given on the command line and emails them out.
	       Patches can be specified as files, directories (which will send all
	       files in the directory), or directly as a revision list. In the last
	       case, any format accepted by git-format-patch(1) can be passed to git
	       send-email.
	
	       The header of the email is configurable via command-line options. If
	       not specified on the command line, the user will be prompted with a

You need to look at this from the right vantage point: the POV of me
(or someone else) who needs to install changes in such an email.  I'm
on the receiving end of the email, so I have no idea what command(s)
were used to create and send it.  All I see is a random email message,
not unlike many others, just with diffs in its body.  You suggest to
pipe it into Git, but how do I know it's in a proper format to be
processed correctly by Git?  There's no clue.  I need to read the
relevant parts of the email to verify:

 . that the Subject line is appropriate for the heading of the commit
   log message
 . that the From header names the author, and was not rewritten in
   transit by some mailing-list software or another MTA
 . that the Date makes sense
 . that the diffs weren't wrapped by whatever MUA was used
 . that the diffs and the body are properly encoded

And even after all that, I can never be sure that Git will process the
patch, because my decision that the format is proper is just a guess.
Any single problem I missed, and I get to recover with "am --abort",
clean up my repository, find out what was wrong, etc.

All of this wastes time and energy, which adds up when you need to
process more than just a couple of submissions.

By contrast, when the changes are formatted by "git format-patch" and
included in the body, preferably as an attachment, the patch has a
clear-cut signature, it has its own "From" header that identifies the
author independently of the address from which the email was sent, it
has the commit date independent of the mailing timestamp, and I can
trust its encoding.  In this case, I just pipe into "git am" without
much effort.

Do you see now why we prefer the latter?  And it isn't like Emacs is
the only project; many GNU projects also prefer to have patches
submitted in this format.

Thank you for taking the time to spell out how messages produced by
git-send-email can be challenging to distinguish from handcrafted
submissions.

Indeed, I agree that it's not uncommon for contributors to send emails
with "[PATCH]" in the subject and the diff appended at the end; it would
be unreasonable to ask maintainers to be able to guess how the message
was produced just by eyeballing it.

Likewise, it would be unreasonable to ask maintainers to pipe random
messages to git-am to find out if they have been produced by
git-send-email; when I said:

> - for maintainers, no need to scan the mail for attachments; just pipe
>   the mail itself to git am.

I really meant "*when maintainers know the mail has been produced by
git-send-email*, there is no need to scan it for attachments; just pipe
it straight to git-am".

FWIW, git-send-email adds a pretty explicit header[1] to inform
recipients of how the message was produced.

I'm certainly not as well-versed in email mishaps as GNU maintainers, so
I'll trust you when you say that attachments fare better than message
bodies vs. the many transit/encoding problems you've listed.  OTOH I
also see that projects working with git-send-email seem to be none worse
for the wear[2].

My email setup hides all X-* headers when it displays messages,
because those headers are just noise, and AFAIK are not generally
meant for human consumption.  (There's a command to toggle their
display, but doing that is another nuisance.  Also, a typical message
coming from debbugs has about a dozen X-* headers, so again,
discovering that one header is not easy and calls for careful reading
of boring content, better avoided.)

So do we, see CONTRIBUTE.  We just ask that git-send-email be used
after formatting the patch explicitly, so that all its decorations
appear in the email body.  If nothing else, this facilitates including
unrelated discussions with the patch without risking them winding up
in the repository.

Fair enough.  Should the wave of git-send-email contributions turn out
to be unstoppable, at least the existence of this header means it won't
be too hard to write a function to automate this check ;)

Mmm, now that you mention it, I'm confused.  Here's what we say in
CONTRIBUTE:

I just tried to git-send-email --to=myself a patch file generated from
git-format-patch, and the email I received looks just like what
Konstantin sent to the bug list, i.e.

- the commit's summary line in the Subject field,

- the rest of the commit message at the top of the body,

- some fluff between the "---\n" and "diff --git" lines (a diffstat
  added by git-format-patch; I could have added more comments there,
  like Konstantin did),

- the diff,

- no attachment.

I must be missing something.  How do our instructions differ from what
Konstantin did?  Indeed he ran git-send-email without running
git-format-patch first, but AFAICT this additional step does not change
the end result?

Re: git-send-email

[Paul Eggert]

I mildly prefer patches sent via 'git send-email' to those sent via attachments,
as I can review the patch directly without having to do any extra manipulation
to see it. When I want to feed the patch to git (which is less common than
reviewing it), I can easily save the message into a file and then run 'git am'.

> how do I know it's in a proper format to be
> processed correctly by Git? 

That problem exists independently of whether the message is sent as-is, or is
put into an attachment. That is, "How does one know whether the attachment is in
the proper format?" is no easier to answer than "How does one know the entire
message is in the proper format?".

There are indeed problems with email-sending agents that munge bytes when
sending patches directly. But 'git send-email' is not one of those agents.

Are you using Gnus to process these messages? Perhaps Gnus could be improved to
make this job easier?

With Emacs MUAs I'm familiar with, looking at an attachment is very
easy, almost like looking at the body.  I don't have any problems with
that.

Not if the body/attachment was formatted by "git format-patch".  Then
the patches have a telltale format and signature that identify the
format unequivocally.

No.

Yes, I can also look at an attachment reasonably easily (I'm using Thunderbird
FWIW). Still, it's a bit easier to see email without the attachment. This is
pretty typical among MUAs I've used.

Yes. Hmm, but I thought that this was the case we were talking about.

Is the problem that people are using 'git send-email' to send patches that were
not formatted via 'git format-patch'? That would indeed be problematic, and if
necessary we can add text to CONTRIBUTE to discourage that.

I would like to not have to bother with Org syntax at all, but after
using the commands that produce it I see that syntax.  It can be very
confusing to see an unfamiliar syntax after issuing a command — what
parts of it may I edit?  When I accidentally remove parts of it, how can
I restore the full syntax?

Two things would help here, in my opinion:

* hide the textual representation.

  My Org mode configuration replaces “*”, “**”, “***”, “****” with
  “bullets” like "◉", "○", "◇", and "◇".  I can produce them either by
  tying “*” (if I know that syntax) or by using M-RET and S-right.  Org
  mode hides the syntax for URLs when [[…][…]] is used and displays just
  an underlined and clickable URL.

  For source code blocks I replace “#+begin_src” and “#+end_src” with
  markers like ✎ and □ and set the block visually apart by customizing
  the faces. (See https://pank.eu/blog/pretty-babel-src-blocks.html)

* delete the whole construct instead of deleting characters.  Currently,
  it is easy to end up with invalid syntax by deleting parts of the
  markup text.  Deleting the trailing “c” of “#+end_src” at the end of a
  source code block, for example, breaks that code block but leaves the
  “#+begin_src” and now incomplete “#+end_sr” where they are.  I need to
  know that I have to append a “c” at the end to restore the code
  block.  There is no command I can run to “repair” this code block.
  Maybe it would be good to remove the whole textual markup at once,
  leaving only the user-provided text that was marked up.

By making it impossible or very unlikely to produce incorrect markup and
by hiding the markup syntax itself the user wouldn’t have to learn it
and also wouldn’t be exposed to it accidentally.

At that point the syntax itself becomes secondary; this would then be
similar to how enriched-mode works.

When I accidentally delete a part of markup, usually '[' or ']' in a
link, it is immidiately reflected visually in the buffer so I just undo
to "restore". For me it is just C-S--.

But I do agree it would be usefull to make some markup "atomic", like
for example "#+BEGIN_SRC", "#+END_SRC". But for some other markup it
might be difficult. For example leading '*': sometimes it might be a
misstake, but sometimes it might be intentionally, for example to change
hte heading from say *** to **.

For the Guix project I wrote Mumi[1], an alternative web frontend to
Debbugs, which can be seen here:

    https://issues.guix.gnu.org

The idea was to provide something that’s reminiscent of the Github
experience without abandoning what’s great about the mail-based
workflow.

The official Debbugs web interface also allows you to filter by
submissions with patches and by status, though it may not be easily
discoverable how to do that.

Oh, right, I stand corrected: the "advanced text search" has also a button

"[PATCH]"

I’d also like to note that this list can be invaluable when rebasing
commits and resolving conflicts.  It’s not strictly necessary (just like
other parts of a version control workflow are not strictly necessary),
but it can serve as a sanity check in a time when the diff is not
authoritative as it is in flux.

An explanation as to why things were done is also very useful in those
cases, but an overview on the *conceptual* changes at the procedure
level (rather than the plain diff that’s only concerned with lines and
not with the context in which the changes occurred) provides additional
valuable information that the commit diff itself cannot provide.

You can, of coures, browse the code with the diff applied and without
and see the full context in which those lines were changed, but even
with a nice interface like the one magit provides that’s much more work
than looking at the commit summary.

While it may be useful, but explicit examples may be more interesting. Right now
when I read your text about this list in the context of resolving rebase
conflicts, I only see the downside that if the conflict came up because a
function was renamed, you need to go fix the commit message too.

Even worse: if upon rebasing a function was renamed, you may not get any
conflicts (i.e. because thunk you modified didn't include the beginning of the
function), and now your commit message is broken without you even noticing.

It is possible, it's just that I do not see this. Convincing someone that the
commit message with the list provides more benefit than without it requires
examples that make it explicit. 

So far the whole thread (both this part and the one with Dmitry) had only
negative examples, i.e. why having the list is a burden to anyone.

Let me sum up the positive mentions: so far, you just say it simplifies review
for you, but I don't know your workflow, there may be many factors that make you
assert that, which does not necessarily applies to everyone. Dmitry said the
list makes better commit messages from novices, but again when I tried to dig
deeper, that discussion died.

You see, presence of negative examples and lack of positive ones doesn't make
that look too convincing.

There's no requirement to retroactively fix commit log messages when
files or functions are renamed.  The renaming is recorded in the
history and can be found when one needs to explore the history of some
code fragment.

What is important is that the log message names the files and
functions/macros/data structures as they are called at the time of the
commit, because the log message is many times read in conjunction with
the diffs.

So I don't think the difficulties you describe are real.

The GNU Coding Standards were recently changed to provide the
rationale for having this information in the log messages.  Since the
official Prep page wasn't updated yet, I show the relevant text below,
in the hope that it will give you enough information to understand why
having that in the log messages could be beneficial.

When you contribute changes to a project, you need to satisfy the
workflows of others, even if they differ from yours.  So you need to
respect the opinions of the project developers when they tell you this
information is of help to them.

Here are the excerpts from the latest GNU Coding Standards manual I
mentioned above:

----------------------------------------------------------------------
Therefore, change logs should be detailed enough and accurate enough
to provide the information commonly required for such @dfn{software
forensics}.  Specifically, change logs should make finding answers to
the following questions easy:

@itemize @bullet
@item
What changes affected a particular source file?

@item
Was a particular source file renamed or moved, and if so, as part of
what change?

@item
What changes affected a given function or macro or definition of a
data structure?

@item
Was a function (or a macro or the definition of a data structure)
renamed or moved from another file, and if so, as part of which
change?

@item
What changes deleted a function (or macro or data structure)?

@item
What was the rationale for a given change, and what were its main
ideas?

@item
Is there any additional information regarding the change, and if so,
where can it be found?
@end itemize
[...]
Following the free-text description of the change, it is a good idea
to give a list of names of the entities or definitions that you
changed, according to the files they are in, and what was changed in
each one.  @xref{Style of Change Logs}.  If a project uses a modern
@acronym{VCS} to keep the change log information, as described in
@ref{Change Logs}, explicitly listing the files and functions that
were changed is not strictly necessary, and in some cases (like
identical mechanical changes in many places) even tedious.  It is up
to you to decide whether to allow your project's developers to omit
the list of changed files and functions from the log entries, and
whether to allow such omissions under some specific conditions.
However, while making this decision, please consider the following
benefits of providing the list of changed entities with each change:

@itemize @bullet
@item
Generation of useful @file{ChangeLog} files from @acronym{VCS} logs
becomes more difficult if the change log entries don't list the
modified functions/macros, because @acronym{VCS} commands cannot
reliably reproduce their names from the commit information alone.  For
example, when there is a change in the header part of a function
definition, the heading of the diff hunk as shown in the VCS log
commands will name the wrong function as being modified (usually, the
function defined before the one being modified), so using those diffs
to glean the names of the modified functions will produce inaccurate
results.  You will need to use specialized scripts, such as gnulib's
@file{vcs-to-changelog.py}, mentioned below, to solve these
difficulties, and make sure it supports the source languages used by
your project.

@item
While modern @acronym{VCS} commands, such as Git's @kbd{git log -L}
and @kbd{git log -G}, provide powerful means for finding changes that
affected a certain function or macro or data structure (and thus might
make @file{ChangeLog} files unnecessary if you have the repository
available), they can sometimes fail.  For example, @kbd{git log -L}
doesn't support syntax of some programming languages out of the box.
Mentioning the modified functions/macros explicitly allows finding the
related changes simply and reliably.

@item
Some @acronym{VCS} commands have difficulties or limitations when
tracking changes across file moves or renames.  Again, if the entities
are mentioned explicitly, those difficulties can be overcome.

@item
Users that review changes using the generated @file{ChangeLog} files
may not have the repository and the @acronym{VCS} commands available
to them.  Naming the modified entities alleviates that problem.
@end itemize

@noindent
For these reasons, providing lists of modified files and functions
with each change makes the change logs more useful, and we therefore
recommend to include them whenever possible and practical.

It is also possible to generate the lists naming the modified entities
by running a script.  One such script is @file{mklog.py} (written in
Python 3); it is used by the @code{GCC} project.  Gnulib provides
another variant of such a script, called @file{vcs-to-changelog.py},
part of the @code{vcs-to-changelog} module.  Note that these scripts
currently support fewer programming languages than the manual commands
provided by Emacs (@pxref{Style of Change Logs}).  Therefore, the
above mentioned method of generating the @code{ChangeLog} file from
the @acronym{VCS} commit history, for instance via the
@code{gitlog-to-changelog} script, usually gives better
results---provided that the contributors stick to providing good
commit messages.

Are you saying that wrong commit messages are okay? Will it be okay if I make a
v1 of a patch where just one function is changed, and then in v2 I additionally
modify a dozen of others, and won't add their names to the commit message?

Also, what you say here contradicts to your quote of GNU standard, which says
the list is needed to generate Changelog files. Because not fixing commit
messages retroactively will result in wrong Changelogs.

What's the point in wrong Changelog files and wrong commit messages?

Right. Judging by the fact you say this me, I have a feeling you miss the point
why we're even discussing this.

Let me abstract from Emacs a bit. People like different things, which is okay,
everyone has unique life and character. And some like things that would in fact
hurt when applied to others! That's okay too, just don't apply these to
everybody. There're communities for them as well, so it's not like they're
alone.

Now let's get back to Emacs. I hope it's unquestionable that purpose of Emacs
project is prosperity of Emacs project. It doesn't have explicit purpose to
cater to Emacs contributors or developers. But if you ask "how can we make Emacs
evolve and prosper", the "making Emacs contributors, developers and users
comfortable" is hopefully an obvious answer.

Having good developer practices is an implication of "making
developers/contributors comfortable". Which includes, that if some developer
practice (I'm pointing out here to the functions list) 1. carries burden on
everyone, and 2. Makes happy only a few (perhaps, because of their habits or
whatever), we should ditch this practice.

Because Emacs project is not a community of peoples who like a specific thing
that would hurt others when applied to them. Instead it's a community who want
Emacs to evolve and prosper.

Thanks. I should say, it's a big text, half of which basically says "it's cool
to have" which doesn't answer the question "why". So, I'm sorry if I missed some
point while reading this, in this case pointing this out more explicitly might
help.

Regarding the discussion I grasped from it two points:

1. The list is used to generate Changelogs.
2. The standard does not enforce having the list in commit messages if you're
using a decent VCS (which I'd think includes git)

The text then goes into details that generating Changelogs from a VCS alone may
be unreliable. The example it shows can be reproduced on Emacs repo as follows:
if you do `git log -1 -p 50a0126402d`, you'll see some renames, however the
context above the hunk shows not the variable/function being renamed.

I'd argue it would be way more productive to make git produce what Changelog
files need correctly rather than forcing tedious manual work upon everybody. git
already can recognize the context correctly, we just need a specific flag to
only make it show changed functions/variables (ATM it seems not to have it, at
least I didn't find one).

Of course not.

Of course not.  But you could omit the log messages completely in v1
if it is known in advance that there will be a v2.  IOW, the only log
message that really matters is the last one, the one that is going to
be committed to upstream.

It's similar to documentation: it is perfectly acceptable to initially
post a patch without the documentation bits, saying you will provide
one when the code details are finalized.

We are miscommunicating.  You have only a very specific scenario in
mind, whereas I was talking about something much more general.  For
the situations you had in mind (IIUC), only the last variant of the
log messages matters.  If you can get those log message right on the
first attempt, you can omit them in intermediate variants, and just
say you will provide them with the last version.  (Of course, if you
don't get them right the first time, you will get review comments for
them, so it's up to you to decide whether indeed you can afford
omitting them from intermediate versions.)

Also, let's face it: changesets where v2 renames many symbols present
in v1's log are rare.  There's no need to make these rare cases sound
as if they were the rule: they are not.

We are not asking contributors to adhere to some arbitrary and
outlandish standards and practices, or something that satisfies only a
small group of people who usurped the power, so to say.  These are
standards common to the GNU Project as a whole (although minor
variations do exist, and when I submit changes to, say, GDB, I need to
do that according to what GDB developers expect and require, not to
what I'm accustomed to in Emacs).  These standards are the result of
quite a few discussions among developers of many GNU projects, where
arguments not unlike those you present are also voiced and considered.
The result is described in the GCS document, and it includes
rationale that also comes out of those discussions.

IOW, it isn't like some band of people conquered the Emacs project and
now dictates its arbitrary demands to the community at large.  These
requirements are the result of many discussions, and include the
summary experience and knowledge of many people who understand very
well that every additional requirement adds to the burden of the
contributors.

Requirements for contributors are always a fine balancing act, whereby
too few or too many requirements will both produce sub-optimal results
for various reasons.  So let's not pretend that dropping important
requirements to make it easy on contributors is the right solution,
because the requirements are there for a reason, and dropping any one
of them brings a disadvantage.  We need to carefully weigh the
advantages and disadvantages of each requirement.

Actually, the reasons (a.k.a. "why") are presented there at least
twice: once indirectly, by explaining the general purpose of good
change log records, and then once more by providing specific
considerations for keeping the information we are talking about (names
of files and functions/macros/data structures that were modified) in
the log.

> 1. The list is used to generate Changelogs.

No.  The text says that it is recommended to have ChangeLog files in
the release tarball, but it doesn't make that mandatory.

No.  The text leaves this decision to each package maintainer, and
presents important considerations that could and should influence that
decision.

I encourage you to talk to Git developers so that they improve this
capability.  Not sure this is going to happen in practice (knowing how
the diffs are generated, and given that one GNU project using Git
after another sets up alternative tools for overcoming these
problems), but it definitely cannot harm, so by all means go for it.

Please note that I haven't provided example here. From your text you seem to
think I implied scenario where v1 is an RFC, and later patches are actual
changes.

It's not what I had in mind. I rather was thinking about making some change in
v1, and then as result of code review making more similar changes to other
places. As a real life example, while discussing the patch `Replace manually
crafted hex regexes with [[:xdigit:]]`, more places where similar changes can be
applied were uncovered.

In code-refactoring I think it's pretty common to happen. You can't omit the
list in v1 in these cases because you don't know there will be followups.

Sounds reasonable. I'd like to see those discussions though to understand the
background, and maybe even participate in them. Do you have any reference?

Err. Okay, I mean, text does explain it. Was I ever opposed to it? Let me
repeat, I'm all for good commit messages. My point is the functions list is not
necessary for having good commit messages.

This whole thread is dedicated to "why having the list is necessary as opposed
to not having it", and while text explains "why having the list is good" in
general, but it does not make comparison to not using it. There's no answer to
that question.

Again, I don't see why just saying in commit message e.g. "Factor out code doing
X out of all functions", is worse than additionally making the list of those
functions (or is it a bad example, and you have a better one in mind? Great, I
want to hear it!).

I might do it, but I need motivation. If I knew this is the only reason Emacs
has requirement for the functions list, thus having such ability in git would
allow to drop this requirement, I'd do it. Right now people seem to prefer to
stick to having the list for other reasons (which are being discussed in the
text above), so clearly even if git got such ability, it would be of little use
to Emacs.

Many times the first version of a patch is an implicit RFC, especially
for a rare contributor who cannot be sure his or her ideas will be
accepted by the developers.

As another data point, I frequently post my proposed patches without
log messages, because I believe people generally trust me to produce
the right log messages when the time comes.

Fair enough, but massive renames are still rare, IME, and thus the
danger of having to completely rewrite the log messages is also small.

They are scattered across different mailing lists (and across many
months), but you can find many of them on bug-standard@gnu.org and on
gnu-prog-discuss@gnu.org.

Our experiences are different, then.  I find them very important in at
least some cases.

Isn't saying "A is good to have" the same as saying "not having A is
not so good"?

For repetitive mechanical changes, it might be okay.  There's no
argument that some changes don't need detailed lists.  The argument is
whether having them in general is helpful.  If you are saying that in
some cases they are redundant, then we agree at least in principle
(though we could disagree in specific cases).  But if you are saying
they are seldom or never needed or useful, then I disagree, based on
my experience.

It depends how good a job they do.  If they do a perfect job, which
will allow generating accurate ChangeLog-formatted entries without
providing the lists of functions in the log messages, then we might
indeed drop the requirement.

Thanks, I'll look at it.

Right. I should mention though, my experience is not specific to myself. Most
non-GNU projects (actually, all I have seen) don't require having the list, but
do require good commit messages. Peter Hutterer, a libinput and kernel HID
subsystem maintainer wrote a good blog-post in 2009 on commit messages, and this
too did not include having the list 
http://who-t.blogspot.com/2009/12/on-commit-messages.html

I also don't think GNU projects are any good to make examples of. This is my
general experience of seeing how new projects get under GNU umbrella to get
never heard of (which I attribute to points listed in my starting mail, since
most of them are unspecific to Emacs).

But to support this claim regarding GNU, I just did some experiment. I
downloaded git repositories of GNU GCC and Clang, and tried to count
contributors to last 500 commits. I was interested in seeing the number of
occasional contributors. I think that if a project only lives by means of
maintainers and paid people, the project pretty much goes down. Maintainers may
burn out, paid people will move on. Number of occasional contributors shows how
big interest in supporting the development, and they're the ones who at some
point may become maintainers too.

So, I looked at "author email" fields and removed ones with email addresses that
are either clearly corporate or clearly maintainers. Not the most scientific
method, I might have missed a few ones who contributed from their personal
email, but I don't expect the difference to be statistically significant.

So, the command is (I hope my email client won't break it terribly):

    git log -500 --format="%ae" | grep -vP
"@\S*(redhat|arm|suse|google|gnu|adacore|alibaba|intel|ibm|apple|linaro|huawei|c
odesourcery|golang|sony|amd|chromium|nvidia|loongson|accesssoftek|ubisoft|micros
oft|fb|energize|comstyle|nextsilicon|quicinc|azul|gentoo|graphcore|gdcproject|si
five)\.(org|com|de|cz|cn)" | sort -u | wc -l

Results are:
* GCC as of commit 445d8da5fbd: 15
* Clang as of commit 7b201bfcac2: 49

This is some pretty big difference! If I expand the commits range, the
difference increases further.

It depends. If A is free, then sure. But if I gotta pay for A, then I'd consider
my options.

Like I said, latest GCS leave this decision to the project developers'
discretion.

You may also wish to check how long do those projects live, and
compare that with Emacs.  Not every technique that is good for a
5-year project will scale well for a 35-year one.  In my work on Emacs
I quite frequently need to look at changes made 30 years ago, using a
different VCS.

I hope you realize how saying that makes your opinions matter much

GCC is alive for 33 years, so I think your theory eats dust.  Many of
the GCC and GDB developers get paid for their work, but that doesn't
mean the project is less viable, and the long history of both GCC and
GDB is the proof.

That text described the advantages of having the lists precisely so
you could consider your options and make an informed decision.

This is where I stopped reading and considering your points to be valid.

There are countless things that determine whether a person will
contribute to a project or not — even projects that you “don’t think […]
are any good”.  Pinning a complex behaviour on commit message format is
beyond ludicrous.

Right, as well as not every technique that was good 35 years ago is still as
good nowadays.

No, I don't. Are you implying that voicing bad opinion regarding GNU on a GNU
mailing list may lead to some people to start ignoring me? If so, I'm fine with
it. You see, my opinions are based on facts. My interpretation of them may be
wrong, but if I expressed them, I am not aware of it. On this mailing list, we
carry technical discussions, which means expressing arguments and counter-
arguments based on facts, and being ready to turn out to be wrong.

Ignoring someone based on their opinion instead of trying to prove them wrong is
not a technical behavior. These are not very technical people, they sometimes go
personal, so if their reaction is a silence, that's fine with me.

FYI, for me even participating in discussions is hard, for personal reasons. But
I am a software engineer, and I get the boundary between personal feelings and
technical discussions, so I get over it.

Okay, let me say beforehand that both GCC and Clang are very active projects
right now. Just in case, so there's no misunderstanding.

So, times are changing. In older times there were no standard to development,
Git was not as popular, development practices are varied too. So, as long you
could get your patch to a project, any odd contribution requirements were fine,
they hardly would set a barrier.

But these days Git got over all other VCSes (and for a reason), so using SVN or
Perforce, or whatever, is a barrier to contribution. 12 years ago Github was
founded, and then also the open-source clone Gitlab appeared. These two pretty
much set the standard development model nowadays (for a reason too). There still
are projects that use other models, but this is a barrier to contributors.

What I'm getting at is that your reasoning that since GCC is 33 years old it
will live on does not work. For a project to "live on" it needs to be active.
Sure GCC is active! But its activity mainly stems from paid people and
maintainers. Whereas in Clang a large chunk of it stems from contributors. Let
me repeat, paid people come and go, so do maintainers (they may burn out, or
just move on). These contributors are the ones who will become new maintainers
and the ones who advertise the project in their environment.

I hope it makes clear the future of what project looks brighter.

I can't make decision since I am not a Emacs maintainer.

Btw, I figured I botched my calculations by using last 500 commits. If in one
project a few persons posted huge patchsets, but in another nobody, then clearly
the latter gets more mails in last 500 commits, which is wrong.

So, I recalculated by looking at date of the last commit of those "500" in GCC,
and used that date on Clang. I made sure to sort out other corporate mails too.
Command I used is:

	git log --since="Jun 8 21:34:46" --format="%ae" | grep -vP
"@\S*(redhat|arm|suse|google|gnu|adacore|alibaba|intel|ibm|apple|linaro|huawei|c

ec-rt|polymagelabs)\.(org|com|de|cz|cn|ai|se)" | sort -u | wc -l

So, now GCC still gets 15, while for Clang this number gets increased to 89.

I think the point is not “this works for a long time and it must be better than new stuff” but rather the current method _can_ live long (proven by gcc & gdb, etc). If in the future people moves to other shiny new SVN’s and github’s, does the git method still work?

This metric is irrelevant.  Basically, you removed everyone who was a
prominent developer, so it's little wonder that you are left with a
small number.  Using such arbitrary criteria, one can "prove" anything
for any project.

Once again, the long history and the active development of GCC over
those long years are a clear evidence that your criterion is
completely off the mark.

Re: Why are so many great packages not trying to get included in GNU Emacs? WAS: Re: Making Emacs more friendly to newcomers

[Stefan Monnier]

I haven't followed this thread very closely, but it seems we've strayed
far enough away from Emacs that it's become quite offtopic.

I may be wrong (since I haven't followed the thread very closely) but my
understanding is that Konstantin would like it for Emacs to accept
submission using a "merge request" model or something like that.

We've discussed this many times in the past.  IIUC, we're slowly going
there (see https://libreplanet.org/wiki/Fsf_2019_forge_evaluation), but
we're an old project, and those people who most contribute to Emacs tend
not to go very much for the shiny new stuff, so if you like the shiny
new stuff I recommend you a healthy dose of patience.

I thought I brought counter-arguments to both of your points in my previous email. Anyway, as Stefan mentioned, it is getting offtopic, so maybe let's not continue discussing GCC and Clang.

I think what Eli and Ricardo (and now me), are trying to alert you to is
that starting a discussion about working methods of GNU projects from a
position of such a broad disdain of such projects ("not any good to make
examples of") is nonsensical and likely leads to your arguments being
ignored, regardless of how sophisticated they are (even though they aren't).

Thank you for elaboration! Well, someone's position per se can not make her/his
arguments more or less valid. They may contradict the position, or they may be
less or more valid… But it is impossible to make correct judgement of arguments
by looking at position alone.

Those (hopefully) hypothetical people basically smugly declare "I am right
because I know I am". Great for them! Bad for others though, because even if
they were right, no one but themselves will know that.

Idk, maybe because I had too wide experience, having contributed to dozens of
unrelated projects, having used a dozen of programming languages in various
paradigms, and having tried to grok various mathematical stuff, but one thing I
used to understand is: "However I am sure I am right, I may turn out to be
wrong". I wish those mentioned people had that understanding.

(Re: 2020-06-20T08:42:41Z!eliz@gnu.org)

Thank you for following up on this.  I'm pretty sure just removing the
sentence about git send-email wouldn't have been enough, as I expect
some people could read "use a shell command like 'git format-patch -1'"
and think "oh well, git send-email will work just as well then".

I think your amendments make things a lot clearer.

FWIW, I just fooled around with rmail and mboxes from Debbugs; adding

- "\|^x-mailer: git-send-email" to rmail-nonignored-headers
- "\|^x-mailer:" to rmail-highlighted-headers

makes it slightly easier to spot patches sent by git send-email AFAICT.
Of course, I'm not an rmail guru; there probably are better ways to
solve the recognizability problem.

Hi Juri:

I tried this and it works pretty fine auto hiding the tab-bar. But I
have an issue.

when I add this to my init file:

(setq-default tab-bar-show 1)

then, if I open a tab with `C-x t 2` it shows the tab-bar and the new
tab, but I don't get bindings like `C-TAB`; but I get the `C-x t o`

After some checks I see that the problem is that in spite of I see the
tabs, the variable tab-bar-mode is still nil.

Any help?
Thanks in advance,

Ergus.

I was intrigued by this, and today checked out the feature/pgtk branch
and compiled Emacs --with-pgtk.

The branch still retains the X connection after the last window is
closed on a second computer, and terminating the ssh-connection with ^C
terminates Emacs.

I.e. what I talked about here:

 · https://lists.gnu.org/archive/html/emacs-devel/2020-05/msg01353.html

However, if I remove the workaround - the if() that sets
terminal->reference_count to 1 in frame.c - and connect to a running
pure GTK Emacs from a different computer displaying a remote X window
using emacsclient, and then close it, Emacs keeps running on the
original screen and GTK does not spew an endless list of warnings.

So the original long standing GTK problem¹ is indeed solved by the pure
GTK branch.

That makes things work for me if I C-c the ssh connection, but if I
kill the ssh process, emacs still exits because itʼs crashing

If you have to C-c the ssh connection, the patch is not doing what it is
supposed to, so either you or I messed up.

I think weʼre testing different things. Iʼm doing:

1. On A: start emacs, run a server
2. On B: ssh -X A, emacsclient -c
3. On B: kill the ssh process
4. Emacs crashes

If in step 3 I C-c the connection, then with your patch Emacs
survives.

Yes, indeed we are. I am diverging:

 3. On B: close the emacsclient frame
 4. On B: exit ssh
 5. Emacs survives.

Without the patch, after (my) step 4 the prompt isn't returned until you
press ^C in the shell, and when you do press ^C, Emacs crashes.

IIUC your patch solves the problem when the network connection is
reliable, but Emacs still crashes if there is an abrupt disconnection.

Looks like an improvement :-)

IIUC the difference (with the patch) is between stopping ssh via `C-c` or
via `kill`.  I wonder why this matters, and I think it's not at all
obvious if an "abrupt" network disconnection would be more like `C-c` or
more like `kill`.

In the 'C-c' case Emacs has had a chance to clean up its internal
state (with the patch applied). With 'kill' weʼre pulling the rug out
from under GTK (see the backtrace several messages up-thread).

Why?  What does ssh do that is gentler?

I suspect it then also depends on the `kill` signal.

In my WM (ctwm), I can also distinguish between `f.delete` and
`f.destroy` where the first sends something like a WM_DELETE request to
the application (which Emacs treats via `handle-delete-frame`, IIRC)
whereas `f.destroy` asks the X server to cut the connection AFAIK.

Would `f.destroy` be more like the `C-c` or the `kill` case of ssh?

I assume itʼs just shutting down the X forwarding connection
gracefully. Since that doesnʼt result in Emacs losing its existing
local display connection, thereʼs no crash.

A recent blog post:
https://tychoish.com/post/the-emacs-daemon-gtk-bug-a-parable/ made me
aware of the continued discussion that happened on the GTK issue 11
months ago, which I had previously missed.

A very interesting comment is this one by Michel Dänzer:

    FWIW, the upcoming release 40 of mutter (which uses GTK3 for drawing
    X11 client window decorations) is able to survive Xwayland dying
    abruptly, using the new XSetIOErrorExitHandler API (which removes
    the need for longjmp hacks) available as of libX11 1.7.0.

     · https://gitlab.gnome.org/GNOME/gtk/-/issues/2315#note_1052481

Which sounds like exactly what is needed, doesn't it?

Switch from using the current XIOErrorHandler to the "new"
XSetIOErrorExitHandler API to avoid the longjmp and the sketchy patchy
hackery I ended up with.

This API is available in libX11 1.7.0 - I just checked the version in
Debian stable, and it is 1.7.2, so it's not some outrageously new
bleeding edge addition.

Now we just need someone with libX11 API chops to start ... eh,
chopping!

It doesn't work.  The part of Mutter that inherited from Metacity is
special in how it uses GTK for various reasons, so it works for them.

The call to longjmp is not the problem.  Rather, it was the original
workaround.  Removing the longjmp will just make GTK call _exit upon an
IO error, which we cannot avoid.  (See for example the
`_gdk_x11_display_error_event' function in the GTK source code.)

I tried to do a proof of concept using XSetIOErrorExitHandler to prove
it was possible to kill the display and still have a gtk app running.

https://gitlab.gnome.org/enometh/simple4/-/raw/master/simple.c

which seemed to work. the code is a bit crufty as it includes the
longjmp path , and i have to reread it to understand it and my headaches
are interfering with thinking. When i checked there was some other snag
in moving this to emacs

    Display *dpy = gdk_x11_display_get_xdisplay(gdpy);
    XSetIOErrorExitHandler (dpy, x_io_error_exit_handler, &done);

=>  window = gtk_window_new ();
    gtk_window_set_title (GTK_WINDOW (window), "hello world");

Judging by the absence of arguments to `gtk_window_new', this code is
for GTK 4, correct?

The X and GTK configuration will never work with GTK 4 due to other
fundamental changes in the toolkit, and PGTK will not be able to access
X-specific APIs.

Thanks.

All very sad, yes.

I've pushed a version of the sample code which should compile and run
with gtk+-3.0 - maybe you could take a look.

Could you adapt that code to open two different displays?  AFAICT, it
only tries to open a single display, which isn't the scenario in Emacs.

more cruft pushed. you can echo :2.0 > /dev/shm/display before trying to
retry connection to a display to change it.

However I think the overall approach isn't feasible for emacs: this
approach depends on gdk_close_display to clean up and remove any
GSources. i think the mainloop crashed elsewhere when some other gsource
fired - i don't have my test code and have to do it again maybe later
this week.

And is it impossible for Emacs to rely on that?  (I know nothing of the
code in this area, but it'd be wonderful if we finally could work around
these Gtk problems.)

I think what he's saying is that `gdk_display_close' doesn't remove the
installed event sources upon disposal, which is similar to what I
experienced trying to fix the problem in GTK itself.

It seems that something in GTK keeps holding a reference to the display,
but I didn't figure out what that was.

I see I had misunderstood what you had said about multiple displays. The
simple.c code assumes there is only one display at a time. I'll try to
handle multiple displays and one display dying first.

This bug is still present on the master branch.  The attached patch
works for me but it may be subject to race conditions, so I will
continue testing it.  In the meantime, I figured I would reply to this
old thread in case others are interested in trying it.
