In that mega thread about modernising Emacs, there was a lot of talk
about getting more data about how people use Emacs, and then...  do
something accordingly.

Behold: https://emacssurvey.org/2020/

So here's the first thread about actionable takeaways from the survey.
(Consider all arguments about the survey not being representative as
having been made already.)

Of 7.3K respondents, 5K disable toolbars, which is more than two
thirds.  So perhaps toolbars should default to off?  I know toolbars
were all the rage in the 90s, but that's apparently not the case now.

Opinions?

It concludes that besides Emacs, writers are the next group of people who make extensive
use of Emacs.  One consideration is to improve and enhance tools for writers.  Special
functionality for writers are Org-Mode, Texinfo, Org-Capture, Calendar, Agenda, Diary.

Whilst the last few are of minor interest to programmers, they have value for writers.
Another area is Accessibility.

I put the word "Toolbars" in the subject of this message because it's
about toolbars.  If you want to discuss other issues, I suggest you post
about that elsewhere.

2¢: keep them, though with prettier icons.  It's trivial to disable them, but it's not trivial to discover that they exist if they are disabled by default.
(FWIW, this is a general philosophy: I think Emacs should ship with a lot more stuff enabled by default, maybe with a spartan-mode to revert to the current defaults.)

I agree with Clément, for a total of 4 cents.

Also, I don't think that there is a clear majority of users disabling
the toolbar: instead, it looks like a majority of the respondents
(which do not necessarily form a representative sample) disable all
three bars and the splash screen, with a few disabling only the
toolbar. So if anything, the take-away is that it's not a
one-size-fits-all situation.

On the topic of enabling/disabling ui elements, I'm curious about the
visible-bell answer. Could it be that the question asked if they
disabled the visible bell, to which the logical answer for those
setting 'visible-bell to t (in order to disable the audible bell) is
no. In this case, the only yes would be users either disabling all
bells, or keeping the default bell AND knowing about it.

It would be interesting to know how many users would want to disable
the bell altogether if they knew that it is possible.

Only small subset of users answered the survey. Emacs is used by much larger number of people. One can see that survey says that users who did answer the survey are on level higher.

If you disable the toolbar you are doing it for those who answered the survey, not for those coming to Emacs, larger number of users. 

If I rememberv well survey also shows that large number of users use it since shorter time like one year meaning that larger number of users drop in the first year. Finding that cause and improving there would keep those users.

Although I disabled the toolbar when it first appeared (in the dim and
distant past), I think it's a good idea to leave them on by
default.  They are easy enough to disable and provide help for the true
neophyte.  In fact, learning how to disable the toolbar is probably a
good first exercise in customizing your Emacs!

FWIw, I believe the toolbar should behave a bit more like the
header-line: it should not "default to off" but instead it should only
exist in those buffers where it is useful.

IMO a toolbar should contain things that are used often, and by "often"
I don't mean "in most sessions" but rather often enough that the time
taken to pick it from the menu-bar would be excessive.
Contrary to the menu-bar, the toolbar is not a good way to advertise
Emacs's functionality because there just isn't enough room to put that
info, so to justify its existence it should be *useful*.

For most major modes, it's hard to find a justification for a toolbar,
and for some major modes, OTOH, it's a no-brainer (e.g. mpc.el).
But I don't think we've done a good job of making use of the toolbar for
the middle ground.

IOW, the current tool-bar is a mechanism that we haven't really tried
hard to make use of it.  Maybe instead of "actions" it should mostly
contain "toggle buttons" for minor modes (and maybe these would need to
be new minor modes, since most of our minor modes are designed under
the principle that they're not toggle at a high frequency)?

True, there are modes where the toolbar may be useful, and a media
player might be one of them.  And prev/next/reload in a browser may be
something people might use.  But there aren't a lot of these modes, and
you may as well put the buttons in the mode line, which is already
there, and which nobody much disables.

If you compare the Emacs mode line with a modern "tool bar" (for
instance, the Crome line at the top), they're not that different.

I don't think that's a good argument for having a GUI element that few
people like, and which may well be discouraging people from using Emacs
at all (because it looks useless and out of touch).

It occurs to me that rather than enhancing emacs, we are regressing it.
What we need is better functionality for some users which is not about
enabling or disabling a long known feature.

As one can see, few users program in lisp.  Consequently, assuming
that people are knowledgeable about elisp programming is wrong.

Quite correct.  If we really want to modernise emacs, we got to become
serious.  There is a section of people who do not want graphical
elements, and the question was there mainly to appease programmers
who want old style customisation (no menu, no scrollbars, etc).

Toolbars are there so people who use the mouse can enable frequently
used commands using the mouse.  If the plan is enhancement, then.

1. Let Emacs enable people to add things to the toolbar for commands,
   without having to use elisp programming.  The survey suggests that
   those focused on elisp are a minority.

If we want to appear by default more like other GUI apps out there,
then we should bite the bullet and show some widget that allows to
toggle on/off those parts of the UI (tool bar, menu bar, scroll bars,
etc.), like they do.

IOW, turning off the tool bar by default and leaving the users with
"M-x tool-bar-mode" to turn it on is IMO a step back in usability
which will leave us with a poorer UI.

I like that take.  I tried to do this in fstar-mode: by default, opening an F* file will also re-enable the toolbar in F* buffers even if it was previously hidden by the user, and most users don't seem to re-disable it.  In fact, many users seem to use them even for features that are bound to convenient keys.  I have seen the same thing for beginner users of Proof General (PG also includes specialized toolbars).

FWIW:

1. I agree with what Stefan said.  Buffer-specific
if possible.  Most modes don't justify it on by
default.  (But I don't think it matters whether we
decide that tool-bar buttons should only or mainly
be for toggling something.)

2. I think that the default "on" state should be
that provided by `tool-bar-pop-up-mode' from my
library `tool-bar+.el' (or similar).

https://www.emacswiki.org/emacs/ToolBar#tool-bar-pop-up-mode

tl;dr: Save space without sacrificing discoverability
or availability of the tool-bar.


Advantage relative to showing the tool-bar:

 Instead of sacrificing an entire line of tool-bars
 (vertical space), you sacrifice the horizontal space
 of an additional menu-bar menu.

 Not a real menu, but a menu name that's really a
 button that opens the tool-bar for a one-off action.

Advantage relative to not showing the tool-bar:

 Discoverability.

The tool-bar+.el code (any or all of it) could be
added to Emacs.  Or the design can be used as
inspiration for something similar.
___


The same library also provides another minor mode
for the tool-bar: `tool-bar-here-mode'.  This is
the same as 'tool-bar-mode', except that it affects
only the current frame.  This saves real estate on
frames other than those where you've chosen to have
a tool-bar.

I fully agree with Eli Zaretskii.  We have really started on very bad
ideas.  Debating about disabling or enabling a toolbar (in general, the
question was about disabling graphical tools, completely antithetical to
modernisation) is of no real value.

I guess it would be interesting to also find out what the connection is
between newer users and toolbar usage. I personally think that the
menu-bar is more than enough (though also not necessary), and that the
toolbar is inefficient, and even if it were, it's underutilized.

People who use the TUI mode or "distributions" also usually don't have
to disable it, so that might also be a factor that has to be considered.

The advantage of the menu-bar is that we can have the associated
keybindings displayed.  And that would be extremely useful for users.
They can use the menu to find the associated key binding.  Yet, the
advantage of finding the keybinding from the menu-bar is not fully
realised.  This is one thing that could help new users.  A serious
improvement would involve updating the keybinding strings in the
menu-bar according to what is specifically defined by the customisation
of the user.  Particularly for people not using a querty keyboard.
For instance, adapting keybindings for use with the Dvorak Keyboard
would be a significant improvement.

Is there something stopping Emacs from including
a key binding in the mouseover help text (tooltip
or echo area, depending on `tooltip-mode')?

That doesn't happen now, but it could, couldn't it?

At some point on the past it was decided that having a toolbar was a
good thing. Switching it off just because a very poorly executed survey
barely resembles a democratic vote on its utility, without revisiting
the original motivation, is questionable.

Really, this kind of decissions should be based on guidance by UI
experts. Sadly, it seems that we have none onboard, same as every other
Free or Open Source projects around (and even most propietary ones).
They are very scarce.

BTW, I disable the toolbar (and the menu) on my config.

I think for dvorak users a good tip is remapping C-t to C-x
--8<---------------cut here---------------start------------->8---
(defmacro wiki/bind-dvorak-helper (key fn) 
                    `(global-set-key (kbd ,key) ,(if (listp fn) fn `',fn)))
(wiki/bind-dvorak-helper "C-t" (lookup-key global-map (kbd "C-x")))
--8<---------------cut here---------------end--------------->8---

After doing above You would need to be careful when on dired. (C-t).

Also map C-c C-m as execute-extended-command
--8<---------------cut here---------------start------------->8---
(global-set-key (kbd "C-x C-m") 'execute-extended-command)
(global-set-key (kbd "\C-c\C-m") 'execute-extended-command) ; {from effective emacs}
--8<---------------cut here---------------end--------------->8---


[...]

That would appreciated by new users as they would have a convenient
and intuitive way to know the key binding.  This without having
to use keybinding ("C-h b", "C-h k", "C-h f") to find out about frequently
used keybindings.  Immediately getting to use  ("C-h b", "C-h k", "C-h f")
can be overwhelming to new users, particularly for school aged kids (aged 7-14).

Quite correct Mr. Ramírez.  The important thing for Productivity and the eradication of

For your insights and considerations1, personally toolbar is definitely
great when working with the mouse and interacting with other
applications. Especially when trying to work with one hand it is
great. For staff members who need to save files or open new notes
quickly it is great. Even more icons would be great to have, there is
so much more space. Tool bars make Emacs user friendly for majority of
new users as people are used to using mouse.

It should even get its customize or defcustom possibility.

Maybe I'm too cynical, but can a non-Emacs UI expert really help with
something as other-worldly as Emacs? And I don't even mean this in an
elitist way, just that it has so many conventions and usage-patterns
from parallel UI traditions, that it might seem easier to just start all
over (which I'm not advocating for).

Majority of users for the survey, if I remember well, came from
Reddit. There was description where it was marketed mostly.

Thus survey is not general Emacs survey, it is survey of mostly Reddit
users who may be or probably are more skillful.

If it would be general Emacs survey with general group of users mixed
with beginners, intermediate and advanced users and they all say by
majority they need no tool bar that would be valid information.

It looks that it is just specific group of more than intermediate
users of Emacs that disable toolbar.

Usability advises by Nielsen can definitely help, see here the outline
of a test: https://www.nngroup.com/articles/usability-testing-101/

If we have clear proposal on testing, I can provide the test with 5
people around me and give you results, then few other people can test
other few people and provide results. Or one built-in usability survey
can be delivered with Emacs or answered straight by people from Help
menu. It does not cost more than effort, not money.

That would accumulate data over time to know what people need and want
and how to improve the interface.

Absolutely.  The argument is not about using the keyboard or using the mouse.
In regards to strain injury, there are two important aspects:

1. Not stretch fingers
2. Not move wrist

In addition, if the user normally uses keyboard, it makes sense that
he continues using the keyboard, rather than having to switch to the
mouse.  This is largely agreed among programmers.

The problem started when programmers starting demanding for Emacs
to focus only on the keyboard.

For those who primarily use the mouse, they should continue to use
the mouse for most things where the user could use the mouse.

As regards development, Emacs could have minor-modes for the
following categarisations:

1. Mainly using the Keyboard
2. Mainly using the Mouse
3. Mainly using Querty
4. Mainly using Dvorak

Furthermore, most people disregard Accessibility.  For instance, KMouseTool clicks the mouse
whenever the mouse cursor pauses briefly. It was designed to help those with repetitive strain
injuries, for whom pressing buttons hurts. KMouseTool also eliminates the pain caused by clicking
the mouse, helping many people to use the computer without pain.

And to work with the mouse makes menu-bar a definite requirement - no arguments there.

That works for me as well.

Lots of eye candy by default to seduce new users, followed by easy ways
to configure the UI for higher productivity (which is why I turn off the
toolbar; keystrokes are more efficient than mouse movements, and this
gives more screen area for text).

Now start all over, but transition certain modes, or write new modes.  
We should not be afraid to throw away old functionality if things get
better.  Ultimately, Richard Stallman started his grudge because using
the printer ended up not being convenient for him.

I do not see many with the Stallman's Approach - I can do better, I have the skills, and
I will write new code, from scratch if necessary.  Only after about 8 years of Gnu did we
start to see operational advantages.

This reminds me of Tevye in the village of Anatevka in the opening number
"Tradition" of the 1964 Broadway Musical.  Emacs must be for worldly people
today, as was being for done for worldly people in the 80's.

Spot on.  We can then just use emacs modes to switch.  New users will not need to do anything,
whilst experienced users can change modes.  The problem that most computer users do not use
Gnu is because most computers don't come with a Gnu System Pre-Installed.

Do people ordinarily change much on their phones, car, etc... No.  What we offer is that    
if you want change and have the skills (or can get someone with the appropriate skills)
you are in a position to do so.  But do not give new users more problems by demanding they
use the manual and learn elisp to customise the operation of emacs.  Rather, the Emacs Mantra should
be:

------- Emacs Mantra -------
Those with skills have the possibility to adapt emacs to their needs, once they read the manual
and learn elisp programming.

Accessibility Tools must function by default.  Then one can make changes if they want to.
How can a person with certain limitations use free software when Emacs Accessibility Tools 
gets disabled by default???

This is a general introspection not only focused on Emacs.  But Emacs developers must 
remember these things if they want to be considered as serious people.

I also think the poll is heavily biased in favor of either Reddit users 
(who are largely either power-users, or those who inspire to be), or 
experienced Emacs users in general.

For vast majority of them, disabling the toolbar is a trivial task. The 
ones who it really serves are less experienced users, non-programmers, 
etc. I don't think we have any significant data on that segment.

Furthermore, features like this can have a very strong survivor bias: if 
the toolbars are bad, users will disable them. But a better answer would 
be to improve them instead.

Rather than one poll, it might be worth more to look at similar programs 
(VS Code and IntelliJ IDEA come to mind) which both have a toolbar by 
default, but make it easy enough to disable the "distracting" elements 
of the UI for those who prefer them off.

Wrong Rationalism.  We would be simply be provisioning to a subset of people
based on the trends in society.  It would not be primarily about software 
freedom.  The focus must on the work we should do, rather that disregarding
minority shareholders as done in the corporate world.  For instance, catering
for users with limitations has almost always been about the few - so almost 
nobody cares about that.

For instance, there is only one face theme that adequately passes 
International Accessibility Standards - Modus-Themes. Should
Modus-Themes be the default face for Emacs? - Absolutely!

Spot on.  There are aspects where certain modes are unwanted because they are not
feature complete.  Have found too many instances of lost opportunities in industry
where projects are forgotten in that way.

The people who responded to that survey are certainly not representative
of all users.  They were selected for being users of certain web sites.

That doesn't imply that most users want toolbars.  Maybe hardly anyone
wants toolbars.

So here's an idea.  We could make Emacs display, where the toolbar
would have been, a question:

   Would you like a toolbar here or not?   Yes   No

If you click Yes, that customizes to permanently turn on the toolbar.
If you click No, that customizes to permanently turn off the toolbar.

Each one could offer to click on a web page where you could
register your preference.  That way we would get a complete sample.

We don't make decisions based on how people might "consider" what
we decide to do.  However, you might be thinking of some concrete
advantage or disadvantage of deleting the toolbar.  That could be
important -- would you please spell it out?

Indeed, we should not assume that Emacs users can write any Lisp code.

Are we doing that?  Where are we doing that?

We have non-Lisp ways of making key bindings -- M-x global-set-key,
for instance.  If that is inconvenient or unobvious to use with the
toolbar, can we make it convenient and obvious?

I agree.

Can we arrange a way to program such dialogs from Lisp?
That would be an elegant way to solve all these UI problems.
We tried to do this with Customize, but it doesn't equal the
smoothness and elegance of the customization GUIs of other programs.

Toolbar icons are the equivalent to keybindings for those who use the
mouse.  Rather than arguing about having a toolbar or not, allow the
user to introduce a toolbar icon and associate with it a specific command.

The toolbar can be made to be an accessibility tool for people experiencing pain
when performing keypresses.  If people can introduce a toolbar icon and associate
a keybinding with it, they would be able to use that with KMouseTool to perform
the icon press for them.  And with a virtual keyboard, they can operate KMouseTool
for typing.

In the toolbar? I see keybindings in mouseover text here in both
emacs-27 and master, on both GNU/Linux and macOS.

Yeah, the natural thing would be to put that on a pop-up menu on
mouse-3 -- I think that's a pretty common UI pattern?  And I see that
mouse-3 isn't bound on any of those elements now.

And perhaps there should be some menu to toggle the tool bar/scroll bars
on/off?  That might be there already somewhere, but not in the menu
where it would make sense -- the Options menu...

My impression is that that's not accurate -- there's certainly
experienced people who hang out on the Emacs Reddit group, but there's
also a lot of new users.  (And my guess is that the latter group is
larger, based on the questions I see asked there.)

In the mega-thread about modernising Emacs, the common refrain was that
we needed actual data on what users do.  We now have some data, and I
don't think we should just dismiss that data because of statistical
quibbles.

And the data says that, at present, the Emacs toolbars are not very
useful.  Stefan's point about improving the toolbars so that they become
useful is good, but I'm not sure that's realistic: We've had these
toolbars for decades, and not much has happened with them.  (Except
growing progressively smaller.)

I mean, look at the toolbar that happens when you "emacs -Q": You get an
Emacs with a scratch buffer...  with a "Save" icon.  In a buffer that
can't be saved.  That's how much attention we've spent on toolbars in
two decades.

All the items in the *scratch* buffer toolbar are more natural for a
menu, and they're already present there.

I think that sounds slightly intrusive...  but we certainly could have
something in the menu area for that: A mouse-3 popup that switches the
toolbar on/off, for instance.

I'm not very enthusiastic about that -- it smacks a bit of
"telemetry".  We don't want Emacs to be seen as a piece of software that
"phones home" and leaks data.

It is evident how a lot of the reasoning is flawed!  Making something harder than it needs to be
is good.  Only Conmen complicate things more than they should be.  And only a genius simplifies
complicated things.

One of the most surprising aspects of this study is how often programmers have been proved not only
wrong, but grossly and disastrously wrong in their prescriptions for the ills of society -- and how
little their views have changed in response to empirical evidence of the disasters entailed by those
views.

Emacs core contributors is and probably should remain small
===========================================================

Making something harder than it needs to be does ensure a certain competence. Manual transmission cars
are another example of such natural gatekeeping. You were more assured of a new driver's roadworthiness
if she could work a clutch, more so than if she relied on electronic assists to parallel park.

That's not factually correct.

Only 1/3 of the respondents came from Reddit.

And the number of years repondents have been using Emacs is for 1/3 less 
than 4 years, for 1/3 between 4 and 12 years, and for 1/3 more than 12 
years.

Another 20% came from hacker news, and a bit more - from lobste.rs. 
While it's not a given that those respondents are as heavily into Emacs, 
those forums tend to feature power users as well. Regarding the rest, we 
don't really know.

So 70% of the respondents have been using Emacs for more than 4 years. 
I'd say that's pretty far into the "experienced user" category. 
Certainly not people who need to be told how to disable the toolbar, if 
they want to.

And 70% of the respondents disable the toolbar. Might be a coincidence, 
but there is probably a high degree a correlation.

I'd expect modern toolkits to have such a widget ready for use, given
the attitude of the GUI applications nowadays.

This has existed since day one, see tool-bar.el, where you will find
examples of doing just that (the entire default tool bar is defined
using this method).

It's a big fuckup, particularly when these people continue to insist on their analysis when
the statistics of the data will be biased.  How can then people then expect to be taken
seriously!  Disregard the bad statistics so we can carry on with our argument is their mantra.

That is generally true for any tool bar in any GUI program.

Should we take this opportunity to either auto-save config changes
made via the menus, or put a big red button somewhere saying 'click
here to save settings', or prompt the user to save them when exiting?

Robert

(Iʼve never really liked the toolbar enable/disable menu. How many gui
applications these days let you put the toolbar anywhere other than at
the top?)

There are more important areas for improvement than whether a switch is "on" or "off".
For instance, making auto-complete be part of standard emacs by default, extending the
completion interface to provide an environment for users to concentrate more on their
own work.

Emacs got momentum in the past because of great tools like org-mode, magit, ivy.

Great.  Yes, that was apparently added in Emacs 27.

[I'm still using Emacs 26.3 (can't use 27).]

New users ask questions more often than the more experienced ones. There 
are 50K subscribers to r/emacs and 300 people online just now. Clearly, 
people asking questions are a minority.

The question is how to contextualize the data and what to do about it.

I agree that the toolbars we have are probably less useful than they 
could be.

Well, it actually can be saved, as soon as you type something (C-x C-s 
works), and it's one of the real usage patterns. The button doesn't 
indicate that, though.

But OTOH we have other buttons (New file, Open, Undo, Cut and Paste) 
that a lot of users expect from a text editor.

> All the items in the *scratch* buffer toolbar are more natural for a

Maybe you're right. I checked back, and most contemporary text editors 
don't have a toolbar like we do.

Atom/Sublime/VS Code don't have this kind of editor toolbar. IDEA only 
has specialized toolbars for, like, debugging.

The recent versions of Kate (KDE editor) also seem to have removed it. 
GNOME Builder only has a small number of buttons, and they are on the 
title bar. Geany still has a toolbar, though.

Even MS Word, while it has a toolbar for certain features, has moved the 
basic edit buttons to the window titlebar and made them pretty small.

My sense is that such buttons made sense when a smaller fraction of the
population was computer literate.  These days I would expect them only
on the most simplistic of editors, those still addressing absolute beginners.

Folk using more featureful editors (emacs or otherwise) can be assumed
to have already mastered some of the fundamentals of editing text.  Put
another way, can we not assume that anyone, even those using emacs
for the very first time, has some notion of key bindings (even if those are
C-c, C-x and C-v) and expects New, Open, Save, SaveAs and Close on
a File menu?

Actually, there are a fair number of GUI applications
that pretty much require a lot of mouse clicking - no
easy way to use the keyboard for many things.

And of those there are a fair number that have lots
of toolbar buttons/icons.  And in such contexts it
can sometimes be quicker to click such a button than
to access the equivalent menu item, which might be
nested (whether from the menu bar or a popup menu).

Such things don't apply to Emacs, in the sense that
you're not _required_ to use menus or a toolbar.  But
their existence elsewhere might be an argument for
Emacs supporting them.

I think this expectation is solid, but there's a wrinkle: If the toolbar is
largely aimed at helping new users make use of emacs, then having an
obvious way to do common functionality that _doesn't use the common
bindings_ seems like a good use of toolbar space. Now that the buttons
advertise the emacs bindings for these functions in a new-user-friendly
way, they're potentially even more helpful, since they both provide a clear
way to save/cut/copy/paste/undo, and they also teach the default emacs
bindings for same.

To this end, I'd suggest adding a button to the default toolbar that
launches a short tutorial (in a new frame on gui systems), that talks about
these common actions/bindings, with a next-step link describing why emacs
uses these bindings and how to change them. It should also have an option
to remove the tutorial-launching button from the toolbar.

I can probably put together a prototype of this if people would like, and I
recall some pieces of similar ideas floating around emacs-devel in the past
6-8 months. Would this be interesting to people?

One interesting bit of data from Dick Mao's survey analysis centers around
keybinding sets. Very roughly, about 2/3 of respondents use the default
keybindings, and the other third use evil-mode. The correlation that seems
relevant:

The median evil-modalist is *seven emacs-years younger* than the median
> traditionalist.


Reading the tea-leaves a bit, I think this suggests that at least many of
these younger users are NOT seeing the toolbar normally, since the vast
majority of the ways that a newer user is likely to get to vi-style
bindings (via packaged setups like spacemacs or doom, by following
config-file advice from the community, etc.)  also disable the toolbar.

This supports the (widespread?) theory that for most new users, the toolbar
is present only at the very earliest moments of using emacs, if that.

Absolutely correct.  But many fail to properly realise that.

It is on the opposite side of the spectrum.  If the trend in this discussion
continues, Emacs will be forcing you to use keybindings, no other option.
That is a regression.  Emacs must provide flexibilityon both aspects.  Or at
least the functionality to do so by writing some elisp.

Why would it be more intrusive than the toolbar currently is?
It would occupy the same screen area.

Yes, we could do that, but it would not encourage people to actually

That is a misjudgment.  There is nothing wrong with inviting the user

My suggestion will get us very good data about this question.

I am not sure what that means, or how it would be different from the

Currently one defines a keybinding using "global-set-key" or "add-hook"
in their init file.   Or by using "M-x global-set-key" or something similar.
One then attaches a function, another keybinding or whatever to the user
selected key sequence.

Ok , I will tell you about it.  A User Styled Toolbar.  You name an icon
(rather than a keybind) and associate with it the command (which can be an
elisp function - emacs or user defined).  Same functionality as keybinding
but achieved by pressing an icon in the icon tool bar.  Perhaps the icon can
show text or an icon image (using a name from a pre-defined set).

Functionality can be programmed by the user using elisp.  We just provide
a basic library of utilities so even beginners in elisp can just copy and
paste from a basic template and adjust accordingly.  Same as we are doing
with keybindings.  This will cater to those who want to use the mouse rather
than keypresses.  There could be several reasons for that: Repetitive Strain
Injury, Illness, or Personal Injury.  I can relate to that when I injured my
shoulder blade, arm and wrist, a year ago, and could only use the mouse with
a program that performs clicks and a virtual keyboard.  Deciding the default
behaviour of the toolbar is not important.  But phasing it out or stop work
on it based on a cohort of people who say they do not want it, would be a grave
mistake.  But you don't have to listen to me of coarse.

I have also suggested making modus-themes the dafault face for emacs.  I am reviewing
the WCAG AAA International Standard with Protesilaos Stavrou for finding bugs, and
extend functionality and capability,

I also remember encouraging Jose Marchesi on his Recutils Project back in 2013.  I knew
he was on to something and offered to be its maintainer when he  stopped having interest
in it.  Today, Gnu Recutils is back under active development and has been adopted as part
of the infrastructure of guix and GNUnet.

Nothing, except that people have been conditioned to expect that
changes in options get saved automatically, so we could do that for
them if they make the changes via the menus. On a related note, perhaps
'save options' should be the last entry in the Options menu, to make
it stand out more.

Yeah, the save button stays grayed out and you can't click it, which I
take to be an indication that this toolbar hasn't gotten a lot of love.
I mean, it's the toolbar shown in "emacs -Q", and even that one is
pretty nonsensical.

I think we should consider setting some standards for what should be in
a toolbar, and normal editing commands shouldn't be there.  That is, a
toolbar should be for things that people want to click a lot, like
"pause" in a media player, or navigation commands like "prev/next" in
*Help*.

I just had a peek at the toolbar in *Help* -- it includes things like
"Save" and "Undo".  No wonder most people disable the thing.

In this UX experiment, this user was unable to find that option.  More
data!

But all kidding aside, that's a pretty baroque menu system there, and
putting the options for where the toolbar should be (!) in the same
place is just odd.

Yes.

Yeah, that's weird, and shouldn't be in the menu.  It's a detail best
left to `M-x customize'.

It's the users who know what they want to click, so make them able to
introduce icons with the commands they want.  Someone has said there
already exists some of that functionality.  In my browser I can drag
whatever item I want to the toolbar!

Artists use toolbars all the time.  Gimp has a toolbar you can drag around.
Fantastic.  And Cad Systems rely on them.

It's not obvious how to fix it, though, because an active "save" button 
is like a reminder to save regularly, whereas saving the scratch is an 
explicit, advanced usage pattern.

> I mean, it's the toolbar shown in "emacs -Q", and even that one is

I guess I was somewhat attached to the idea of it because it looks 
pretty and neat on my system (with -Q).

Definitely more so than the splash screen, the discussions about 
improving which have all seemingly fizzled out.

Yes, probably. And if there are not enough of such buttons that we can 
come up with, the toolbar should be hidden for that particular mode.

But... can it work well? Showing the toolbar in some modes yet hiding it 
in others? Jumping window heights are a known source of annoyance.

All the editors I mentioned above that do have toolbars have avoided 
this problem, some way or another.

Yes.  If we want to go in a toolbars-only-in-modes-where-it's-useful
direction, we'll have to fix the height annoyance.  Well, we should do
that anyway...

Not sure I'd like it: it would make it harder to try an option without
committing to using it.

Its current place is what it is because the items below it don't
belong to "Options" saved by "Save Options".  We could add some
delimiter to make that more evident, but it isn't like the place is
random or not well thought of.

??? I'd say it's the other way around: they are insensitive _because_
someone thought about avoiding to trip the user.

> I just had a peek at the toolbar in *Help* -- it includes things like
> "Save" and "Undo".  No wonder most people disable the thing.

I don't understand what you'd like to have instead.  Would you like
Emacs to instead constantly add and remove tool-bar buttons as they
become available/not available?  I think this would be much more
annoying, and will cause even more people to disable the tool bar.

Making a tool bar insensitive is a standard UI way of telling users:
don't click on this, it will do nothing useful at this time.

Took me a few moments to understand what you two are talking about.
You are both looking at a GTK build, right?  Where we allow the user
to control this aspect of the tool bar because GTK supports it?
AFAIK, no other toolkit has that menu item.

So if you want to ask what kind of GUI environment lets users put the
tool bar anywhere but the top, the answer is GTK ;-)

Yes, but as I said: itʼs what people have been conditioned to
expect. Or we could limit it to only visual things like
toolbars,scrollbars etc.

I guess we could add another separator above it.

I assume you mean _some_ people.

If some more than a few people really do expect
setting (option) changes to be saved automatically,
then we could add an option (!) (or a minor mode)
that does that.  Turn on that option, and thereafter
all changes you make to options, faces, themes, etc.
get saved automatically.

Note that that behavior can get in the way of user
experimentation.  Not that it's necessarily limiting
- it's just a different approach.

In sum, if we want to support automatic saving of
every setting change then we should do so optionally
(and opt-in), not just switch to that for everyone.

permanently.

It would be nice if one could see what options one set (via the

The behaviour is akin to cycling color themes without actually changing
the theme permanently.

It is not invariably evident that the contrasts between emacs and the
behaviour of other applications is bad.  Emacs gives users much more
control of what happens.  Thusly, it is quite easy to end up messing
your system with things that ultimately you could not want.

Experimentation, either through User Hacking or through Emacs Packages
is quite a regular thing.

I like the idea.

It can be done as is done with Gimp, nobdy complains about a detached toolbar in Gimp.
I can be as Speedbar is.

Another global solution is this:

  (define-key key-translation-map [?\C-x] [?\C-t])
  (define-key key-translation-map [?\C-t] [?\C-x])

I’ve been using this for many years.

I'd suggest to give that menu entry a more explicit name, "Save Options 
Above" or "Save Above Options", with a separator above (apparently that 
one is already present) and below.

If you have trouble pressing keys, the toolbar will save you at most
a tiny fraction of the keys you need to press to enter some text.

That idea sounds good to me.  Or maybe ask the user whether to save the
change when the user requests a change.

Or offer buttons "Apply permanently" and "Apply for this session".

Dear Richard,

It is difficult to use a mouse clicking tool to perform the keysequence on a virtual
keyboard.  When using a mouse clicking tool with a virtual keyboard, the number of
presses that are saved, stop being a tiny fraction.  It is then the keybinding approach
that gets in the way.

Christopher

Dear Richard,

I like the way toolbars are implemented in Gimp.  One can remove the toolbar because
it is set up in another frame.  Similar to the speedbar.  If emacs could do the same,
the toolbar can be disabled and you would not have the problem of vertical shifting.

Alternatively, one could make the toolbar functionality appear as an additional MenuItem
that you could detach.  By keeping two screens - one side emacs, the other with the detached
toolbar, a mouse clicking tool, and a virtual keyboard - one can mark quite well.

The problem with all this is whether the trend is to get rid of toolbars altogether.  That's
the  real problem.  If a way can be found that does not require the toolbar to take space
on the frame, it could make people who do not want it happy.  The others can have the freedom
to develop the toolbar or do work for others with it.  I would be willing to include it in
my Behistun Package, although have not planned on it.  Then send they code for inclusion
in emacs.  But first one has to see how the emacs code on toolbars is applied differently
by the maintaners as they adapt to the many people that insist on not having the toolbar
visible.

Have not coded in GTK for a long time.

Regards
Christopher

Would you please take a deep breath?  I don't think
there was anything unkind in either what Robert said
or in my reply to him.

Did you actually read what each of us said?  The point
of my emphasis on "some" was elaborated in the rest of
what I said, the point of which was that we can easily
accommodate _both_ expectations of saving automatically
and saving only on demand.

I don't even see any disagreement in what we were each
saying.  Some people _are_ used to automatic saving,
and we can accommodate that while also giving others
what they expect (which is what we have now).

That is also my point on toolbar, it is not useless and can support both.
The current problem is that the toolbar is attached to the Emacs frame,
rather than using another frame.  There is also the possibility of dynamically
adding a new MenuItem.

True, although adding an option that says 'save all changes
automatically' will help those who already know how to make
configuration changes permanent. I was aiming more for the subset of
people who donʼt know that yet.

The only disagreement is whether such an option should be enabled by
default for changes made via the menus, I think.

To give you more insights from me as user, I do use toolbar, sometimes
not. In general it does not disturb me neither I see it. It is useful
as one level of accessible user interface. It offers similar to menu
items specific functions by only using the mouse and a click and that
is great.

Emacs with toolbar is on a level more accessible.

Toolbar is occupying only about one third of linear space on my screen
and in my opinion it should be full of functions such as:

- new frame
- bookmarks list
- text properties such as justification full, centering
- Emacs packages
- report emacs bug
- spell checking
- version control check in/out
- calendar
- calculator
- send email
- then help functions like About Emacs or manual

Including a rich toolbar makes options accessible more to users to
discover more useful features of Emacs.

Including more accessibility features would help that Emacs become
useful for more people.

Gestures would be another useful accessibility feature. But I think it
exists already, I just forgot is it a built-in package. Then user
could move mouse in some direction as specified to launch some Emacs
commands. This would help on touch screen as well.

Accessibility on one level more would be speech recognition where user
activates it by saying "M-x" "find file" or "M-x" "mail" to activate
features.

That depends on whether we would people to experiment without messing
up their setup.   For those who experiment with many problems. they
run the risk of forgetting how to revert to their previous configuration.
Perhaps writing the details in a file, and using that if they want to
revert back?

Have suggested that the toolbar items could be user defined as it is
for keybindings.

"Save Changed Options"? I feel like I may have unwisely wandered too

You mean creating a ~/.emacs.d/saved-changes.el file with a menu
command to undo them? I can't judge how useful that would be.

We're discussing different options.  I don't think somebody has
suggested dynamically adding/removing buttons from the toolbar, though?

What has been suggested is that only modes where it makes sense should
enable the toolbar (and there probably aren't that many where it makes
much sense).

However, that's probably technically difficult -- people have setups
where they've computed the size of the Emacs windows based on whether
(or not) they have toolbars enabled?  So switching the toolbars on/off
dynamically may lead to some difficulties in that area?

Perhaps modes with "action buttons" (like mpc/eww) should just put the
buttons in the header line.  And then we're back to the original
suggestion: Just default the toolbar to "off".

The page has a bunch of charts and graphs, but you have to enable
Javascript to see them.  (And, no, the Javascript isn't free.)

Maybe there code be something like a "fade-in" toolbar, i.e. normally
the toolbar is hidden but when the mouse pointer moves over the top
border it becomes visible.

Toolbar is offering accessibility feature that some functions may be
chosen with the mouse.

Itself it is easily customizable.

But offering toolbar to be customizable such as in defcustom style
would not be accessible by users, it would be redundant as programmers
can already customize it.

What would be accessible is to provide icons for many functions and
let users drag and drop into the toolbar.

Correct, that what I mean.  But also that a toolbar icon could run a user
defined function.

My disagreement with Lars is that he wants that the determination of when the toolbar
can be used is defined by what makes sense to the maintainers of Emacs.

Completely wrong.

The toolbar can be detached like in Gimp when enabled.

But that's exactly the situation I described above.  Suppose you type
"M-x": this enters the minibuffer, where you have a new mode in
effect, and some (most?) tool-bar buttons make no sense.  Would you
like those buttons, or maybe the entire tool bar, to be removed now?

Similar situation exists when I have 2 windows, one of them showing
*scratch*, and switche between them -- would you like the tool bar to
disappear when I'm in *scratch*?

That's another complication, but we could perhaps handle it in some
reasonable way.  Appearing and disappearing tool bar, OTOH, is
something we need to consider seriously before we decide that such a
mode of tool-bar display is sensible.

There's not even any real disagreement there, I think.

My reflex is to not change default behavior willy
nilly, but case-by-case is the right approach to take
when considering such changes.
___

My opinion about this general question is that both
behaviors can be useful.  And each is typically more
useful for some kinds of option changing/setting.

A behavior that I'm likely to toggle often within a
given Emacs session is one whose last state I
typically do not want to save for the next Emacs
session.

A behavior that I'm not likely to change often is one
whose last state I might well want to save for the
next browser session.  (Or I might not.)

For the latter, think of web browser settings.  When
I change such a setting I don't need to explicitly
"save" settings - and that's "natural" behavior.
That's the kind of thing I think you were thinking of
when saying that users are used to such behavior and
expect it.

[You can see that not only do I think this applies
to _some_ users.  I think it can apply to the _same_
user _some_ of the time.]

For the former, think of, say, toggling option
`case-fold-search'.  I might do that many times in
the same Emacs session.  I generally want its saved
value to reflect my preference for the _default_
behavior (which in my case is case-sensitive search).
I don't want it to reflect the last case-fold state
of my last search in my last session.

Note that vanilla Emacs goes out of its way to have
most of its commands that toggle behavior such as case
folding NOT change the option value.  To toggle the
option value you use a specific command for that.
E.g., when you toggle case folding during Isearch that
doesn't change the option value.
___

Personally, I think that for some commands it can
make sense to let users toggle _either_ the option
value or a temporary state.  (Note: toggling an
option value is different from doing that and also
saving the value.  That too can be a user preference
for this or that option.)

For example, in Isearch+ there's even an option,
`isearchp-toggle-option-flag', that controls this:

 Non-nil means Isearch toggling commands can affect option values.
 If nil, the option value remains unchanged - the effect is temporary.

 Applies to toggle commands for behavior that has an associated user
 option.  Currently this means `M-s i' (`isearch-toggle-invisible') and
 `M-c' (`isearch-toggle-case-fold').

If that option is nil then toggling case folding is
temporary, i.e., for the current Isearch invocation
only.  If non-nil then the change persists for future
invocations in the same session.

Similarly, `isearchp-auto-keep-filter-predicate-flag':

 Non-nil means automatically apply `C-z s'.
 Changes to `isearch-filter-predicate' are automatically kept for
 subsequent searches in this Emacs session when you exit Isearch'.
 You can toggle this option using `C-z S during Isearch.

Yes, that was a point I made.

There are good arguments to be made both for and
against auto-saving of option changes.  My message
of a few minutes ago elaborates on this.

Providing for the possibility (choice) of auto-saving
could be a good thing.  Providing flexibility in such
a user choice would be even better.

IOW, even just a choice always/never save all options
could be a step forward, but it's not the best possible
solution.  Options are not all the same, and users
don't all use the same option the same way.

I think Christopher did suggest that.  And I think
he suggested that users even be able to easily define
their own toolbar buttons/icons.

But he'll correct me if I'm mistaken in this.

For some (individual?) definition of "makes sense",
it could well make sense for most modes/buffers.

The point is that different users can work differently.

I already mentioned tool-bar+.el, which lets you
dynamically show and use the tool bar for one-off
use, by clicking a pseudo menu-bar menu name.

The tool-bar appears, you click a button for its
action, then the tool-bar disappears.

Currently this is only per-frame, not per window.

And currently I have to use a menu-bar menu for
the "button" that pops up the tool-bar.  It might
be nicer to have an icon button for this in the
menu-bar, if that were possible.
___


We might also consider having a "hamburger" menu
in the mode-line.  Items in that menu could
show/hide the menu|tool-bar or pop them up for
one-off actions.  That's one more way to save
screen real estate while giving discoverable
access to menus and tool buttons.

`tool-bar+.el' offers something very close to that,
but without the automatic annoyance of it popping
up without explicitly clicking something.

No one has commented on it.  Perhaps no one has
bothered to try it?  It's a single file; just load
it to try it.

A very easy start would be to provide a single button
that is shown only if it has an associated binding/action,
and whose action is user-defined, the value of a user
option.

No, that doesn't respond to all that you request (which
I support, BTW).  But it would seem like a zero-cost
no-brainer, to at least let user get a user-defined
toolbar button.  And the action option could be buffer
local.  You'd at least get a user-definable,
mode-specific button.

Click buttons and tool bar appears, use it and it closes. In my Lucid
toolkit I have to click 2 times Buttons for tool bar to appear. Do you
know that?

No, I wouldn't, which is why I don't really suggest doing this.
Somebody may come up with ideas that makes the proposition workeable,
and I see that Drew has one -- he suggests having a blank toolbar in
these instances, and ... perhaps?  It's a lot of "dead" space real
estate, though, so I'm not really enthusiastic.

In the cases you describe today, Emacs does switch between different
toolbars (if the modes in question have different ones).  For instance,
`C-x m', and you'll get the Message toolbar with things like "Send" and
"Preview".  If you `M-x', Emacs will switch to the non-specific toolbar
with things like "Save", all of them greyed out.  This, perhaps, shows
that Drew's idea is a good one -- it's less confusing showing a
completely blank toolbar than one with all the items greyed out?

I haven't suggested using a blank tool-bar.

Not at all.  The `tool-bar+.el' code that I
pointed to lets you _not show_ (not have) a
tool bar at all, until you click a menu-bar
pseudo-menu.

When you do that Emacs pops up the tool-bar
only for the duration of one action (tool-bar
action or any other action).

There's no blank tool bar - no wasted space.
As the doc for `tool-bar+.el' makes clear,
that's the point: save screen real estate.

It takes only a minute to go to Emacs Wiki,
download `tool-bar+.el', load it, and try it.
You will immediately see the effect, and
won't have to guess.  You don't have to like
it, but you might want to at least find out
what it is (and isn't).

https://www.emacswiki.org/emacs/download/tool-bar%2b.el

Other approaches are possible.  With only
Lisp (no C, toolkit etc. changes), I came up
with the behavior it offers.  Emacs can no
doubt do something better or different.  But
IMO, `tool-bar+.el' is a good start, and it
or similar could be added to Emacs immediately.

Can't the functionality of the toolbar be provided
by a separate package.  Then if one wants it, he can
require it.

You can view it locally using Jupyter Notebook, which is a bit like
Maxima or Macsyma but with Python instead of Lisp, and uses the Modified
BSD license.

On my Fedora machine I installed it with "dnf install python3-notebook",
then run Jupyter with "jupyter notebook commentary.ipynb". It took me a
while to find the right package name, because it doesn't have the name
"Jupyter" in either the name or the short description; an odd choice.

What makes you think that people coming from the Reddit channel are more
skillful? If someone googles an Emacs question, getting directed to
r/emacs and finding the survey there is pretty likely.

You guys should look into weighting adjustment of the data if you think
a population is over-represented.

Shitty data obtained without care, attention, and skill is useless data.  Forget the weighting!

I read these words

    I assume you mean _some_ people.

and saw that things were getting snarky.  "I assume you mean" is a
snarky way of disagreeing if it isn't reporting a typing error.

So I said,

    Would each you please take a deep breath, and respond
    more kindly from now on?

I guess you took that as an attack, rather than as an exhortation,
because you responded by throwing that perceived attack back at me:

    Would you please take a deep breath?

I did as you suggested, and on second reading I agree
that Robert Pluim's words were not unkind.  They seemed
that way when I first read them.  Sorry, Robert.

You continued with

                                          I don't think
    there was anything unkind in either what Robert said

    Did you actually read what each of us said?

Of course.  But only the parts that I cited.

I didn't read the whole messages, or any of the whole messages in that
subthread, because I'm not participating in discussing that particular
question.  If I wanted to participate, I'd have to read the points
made about it.  I decided it was easier just to say nothing about it.

I'm sure it was.  But I'm talking about the attack (against Robert)
that I perceived in the first line.  Not about the substantive point
it was the start of.

That might be a solution I pesonally could use -- if I understood how
to do it -- but there is more at stake than my seeing those graphs.
Much more.
It is not a good state of affairs for this information to direct people
to run a nonfree program, and worse yet, that it happens in connection
with Emacs.

Thanks, I will look.  But that helps only me.  The situation
is still not a good state of affairs, so we could still use
someone to contact Dick Mao.

There's no JS for any of us to delete or to make free. GitHub renders
the notebook using the same Jupyter Notebook software that I recommend
using to view it with, so that's not a problem. It's just GitHub's own
JS that isn't free software.

Of course the graphs could be published anywhere else as well. Well, I
assume that it's not difficult to get Jupyter Notebook to export a
static view of the document, since GitHub does that already… Yea, in the
Jupyter interface, select File → Download As… → HTML. That opens it in a
new tab of your browser, and then you can use your browser to save it to
disk.

That said, I suspect that the notebook is just an intermediate
representation. There's also a notebook in the repository called "Emacs
User Survey 2020.ipynb" which was obviously used to generate the graphs
on the official survey results webpage: https://emacssurvey.org/2020/

I don't know if there's a plan to publish Dick Mao's commentary.ipynb
the same way, but it could obviously be done the same way.

"who may be or probably", see above to understand the intended
meaning.

It is a survey that targeted intentionally or not intentionally just a
subset of Emacs users using Reddit and few other popular websites.

Those who speak about Emacs on reddit in my opinion are minimally
slightly advanced users, as they discuss about Emacs.

I was using Emacs for years without discussing with anybody. Debian
popularity contest says that there is much larger number of Emacs
users.

The true representative survey information could be obtained only
within Emacs itself under condition that survey is presented straight
to Emacs user.

I wonder whether the survey stems from lack of vision of emacs admin and developers.
For instance, Gcc has a Development Plan.  Suggestions for changes to the plan are
discussed on the Gcc mailing list and can be approved or rejected by the Gcc Steering
Committee. How about Emacs?

Statistics give people the starting point to delve into that evidence and see if the arguments
hold together.  Reality must come before public relations for nature cannot be fooled.
I am one of those people discouraged from participating in Gnu development not because of
certain patterns of communication, but of certain patterns of working.
Fluttering Kind Communication Guidelines won't help.

No, it's not.  It's not inherently any such thing.

It, and pretty much anything, _can_ be used to be
snarky.  And pretty much anything can be interpreted
to be snarky, if that's what one looks for or tends
to hear.

You may have "seen" things getting snarky, but
things were not snarky or getting snarky.  The
discussion was only technical, not personal,
until your intervention.

Would you have preferred that I write "I guess"
instead of "I assume"?  Or "Yes, some people have
been so conditioned, and ..."?  Or "Did you mean
to write '_some_ people'"?  If so, please consider
hearing some such phraseology.

My guess is that you may have been looking for
trouble, and so found it.  You may not think so.
And I may be wrong, of course - just a guess.
But maybe think about it.

I think/hope that if you reread all that was
written you'll see that nothing snarky was
intended, and there was no dispute - not even
a technical disagreement, AFAIK.

Qualifying the statement to only some people in
that context was no different from qualifying a
statement about integers to only natnums.  The
goal was clarification.  My point was that Emacs
can cater to more than one expected or preferred
alternative behavior.  Different strokes for
different folks.  Emacs shines at that.

An attack was perceived by you (3rd? 4th?).  It
wasn't an attack.  It was suggesting the same thing
you suggested, as a reply to what I sensed was an
overreaction to, and misinterpretation of, the
conversation and intentions, which were entirely
cooperative.

You advised us to take a deep breath, to step back
from a perceived dispute or snarkiness.  I asked
that you take a deep breath, to step back from an
overreaction.

I was hoping that a deep breath and rereading would
help you see there was no fight to break up, and no
malevolence.

Are you now hinting that only my words were unkind?
I might say I'm guessing that, but I prefer to give
you the benefit of the doubt.  And I'm glad you've
absolved Robert, at least.

We were interested in the question, even if you were
not.  It kind of feels like you weighed in as a
referee of sorts in what you thought was a personal
dispute.  A referee really owes it to all to follow
the action before judging.  Not doing so isn't fair.

That was what I guessed might have been the case.  It
can be easy (for anyone) to misinterpret something out
of context.  And then reacting to that can easily be
unfair.  Context is important.

I hope I've made it clear now, and that by rereading
you'll understand there was no attack anywhere.

Along with deep breaths, please allow me to suggest /
prescribe (all) giving each other the _benefit of the
doubt_.  That can often go a long way toward avoiding
negative misunderstanding.

GCC has many developers who are paid by various companies.
That makes it easier to make plans and actually carry them out.

The Emacs contributors are all volunteers, so we can't tell anyone
what to do.  We can only exhort and apply naked emotional pressure,
which works only sometimes.

I've been trying for more than 10 years to urge people to work toward
giving Emacs the document capabilities of a word processor, but I have
not convinced people to do this work.

I know you're trying to help me look at it, but these are terse
instructions for a program I have never seen.  To try to run it
would imply a lot of time futzing around.  It would mean losing time
I should use for other pending tasks.

Anyway, Caio sent me am image file which shows the results.
So I personally don't need help any more.

But it's still a bad thing to have this posted in a way that tends to
lead people to run nonfree software.  Let's aim to _fix_ the problem
rather than work around it.

Thank you.  It is interesting.

One thing I noticed is that there seem to be difficulties in GUD
(debugging under Emacs).  That is a gad situation.  Can we encourage
users to report the problems, and devote effort to debugging them?

Perhaps not in all details, but at some level it would benefit to
consider an actual plan.  Else things move on quite haphazardly.
For instance, certain changes are better done in a sequence.
And if you are tackling a problem, you can consider tackling
a related one.

We could also motivate by offering small payments for solutions to
unresolved problems.  I am sure there are many whose professional
job is in computing and could get young people to work on some
challenging areas or get their interest in helping out if there was
a plan.

Most people I know don't know what to do or what problems are out there.

There are many volunteer organizations where people make a plan of
action. Volunteer or not, it is not related to planning. Especially if
one wish to spare the time for developers it is better to have a
development plan.

It could be a simple list of most important issues to be handled for
Emacs.

When such list is published maybe more contributors could be drawn to
it.

And I see no reason why FSF donations could not be used to improve
developer's life.

Arguing back and forth who was or wasn't snarky isn't useful, it is
simpler and far more productive to simply say sorry if it came out
that way, no matter if it was ones fault or not and move on.

So instead of assuming that someone is trying to cause a bar fight at
every turn, lets assume that people are doing their best?  Right now
this is escalting based based on someone having percieved something as
unkind or an attack, instead of just accepting that they at the time
read it as such -- for whatever reason, and moving forward.

I didn't interpret what he wrote to mean there's a problem.  I
interpreted it to mean he personally stopped using the Emacs GDB front
end long ago.  So he doesn't really say anything about gdb-mi.el, the
current GDB front end in Emacs.

We have that: etc/TODO.  But that isn't a "plan" in any reasonable
sense of the word, it's just a list of useful features that we would
like to have at some point.  Sometimes, not very frequently, someone
comes and actually takes up one of those jobs.

But much more frequently, someone comes up with an implemented feature
and submits it for inclusion, and we usually accept it.  Since there's
no way to plan that in advance, almost all of Emacs development moves
by such submissions which no one planned in advance.

Frequent contributors to Emacs probably have their own personal plans,
and work according to them as their time permits.  But these personal
plans are almost never coordinated with anyone else.

I don't see how anything different from the above could ever work, as
long as the project continues to be a loosely coupled group of people
with very disparate interests.  (I also see nothing wrong in how we do
things, FWIW.)

It works amazingly by willingness and contribution.

What is in your opinion priority for Emacs?

There's another important difference.  GCC implements programming
languages defined by evolving standards that are developed by other
bodies.  The evolution of those language standards largely defines the
GCC development plans.  Other project, like GDB, Binutils, etc. have
similar traits: they support hardware and software standards developed
elsewhere.

But Emacs is its own standard, defined by what we put into it, it
depends very little on outside developments, and is only tangentially
affected by those external developments.  So those developments cannot
determine our plans anywhere near to how the next C++ Standard affects
GCC development, or the next DWARF2 version and various
debugging-related features in the next generation of CPUs affect GDB
development.

That question is too general to be useful, sorry.  Emacs has a
gazillion different facets, and at least a dozen of fundamental
infrastructure features in very different domains.  There isn't, and
IMO cannot be, a single priority, and moreover, if we'd try to come up
with a priority list, we'd argue till the Second Coming without
reaching any agreement.

I also don't see any sense in trying to define such priorities, as
long as no one but myself will be following them.

I take that as an invitation, and I think that, without a doubt, our top
priority should be finding a more modern default colour for the mode line.

I think it is more important to find more modern font fo the clock when
it is displayed on the mode line.

I disagree!  Let's argue.

One may is to categorise according to separate emacs structures.  Then
have some from each make a plan with a list of five things to do, and
about eight tickets to work on.  And so on.  A few people should come
together, each person focused on a particular thing and the team led
by Eli.  Just don't make it in an argumentative way.  Am quite sure that
notwithstanding disagreements, some tasks could need to be handled better,
and work could focus on that.  Then introduce just one or two hot topics
so that arguments can be managed better.  I would say that it is most likely
that areas of great controversy indicate that the various aspects of contention
have got to be tackled, rather than focusing on one to the detriment of the other.

1. Major Modes
2. Minor Modes
3. Performance
4. Org-Mode
5. Completion
6. User Interface

Could you then come up with your plan as per your decisions so others can see
what's happening with Emacs.  Emacs could need two other people who are skilled
enough.  People have got to understand this.  Although Eli is responsible
and dedicated to Emacs Development, there cannot be just one person fully immersed
in it.

You may be correct, but we all have got an indication of what works better.
Emacs could word on setting some standard for the next three years and get
a bit closer to development plans that have proved to be much more sustainable.

But this is just my position.

There lies the problem.  The project cannot continue to be loosely coupled
with very disparate interests.  The major people involved should come together
as a team.  This means that they should spend some of their time looking at
the other interests.

There are several possibilities that can be used simultaneously

1. For every five aspects tackled, that same person helps another one on one of his tasks.
2. Have two tasks where everyone helps tackling them.

Might not be a very exciting proposition but it would help eradicate
some serious difficulties we are experiencing.

Can you please quote the relevant part of the message you are replying
to ? It is jarring to read a message without any context. That is a
discourtesy to readers, who must work harder to find which part of a
message you are replying to (and some client software makes that harder
by not threading messages properly).

I am not sure what he meant, but he seems to claim, in a vague way,
that it has had problems over the years.  This might refer to real
problems.  In case that is so, we should ask for details.

Would someone be willing to ask him to tell us what he meant,
and where we could look for specifics?

Of course, the users should have sent bug reports, but since they didn't,
let's try to find out what the bugs are.

Yes, we could do that.  It could be a useful practice.
And we would need to make a plan: a list of projects
(not very many of them, I'd think) that are of a reasonable size
and amounts to offer.

Do you think people could be motivated by amounts under hundreds
of dollars?  I tend to doubt it.

Is this because we have not posted it in a clear enough way
or because we have not made people aware of what we do post?

I was thinking to say, ‘Here’s a nice problem, we thought about it for a while, and we 
don’t see how to solve it.  Maybe it’s a $25 problem or possibly a $100 problem.

Or offer things like membership, discounts, entry to LibrePlanet, or have certain
conditions for eligibility for specific internships.

I do not know how willing maintainers would be on offering a few weeks
internships locally.  The project community could contribute a few dollars
to have something comparable to Google Summer of Code for specific tasks. 
 
To really move forward we got to focus on young people with plenty of
enthusiasm and eager to prove themselves.

Have had discussions with many people in the last few years, and figured
out how difficult it is to work with older people who are most often set
in their ways or routine.

Mostly because many need guide and experience to really have their 
own ideas for implementation.  Short manuals describing
topical  overview  areas with plenty of complementary material
on areas that require profound  understanding.

FYI, amounts in order of tens of dollars are not that less if you live
in less developed countries. For example, a pay in non-capital cities in
Ukraine can be in order of 10-20$/day.

Best,

I think yes. Not everybody is too busy and programmers live in various
economical zones that smaller amounts not affordable in US could be
quite affordable for one month of living in some other country.

For example a waitress in Uganda would get monthly US $55 for salary
which would be short as one would need to pay the room, and food at
least. Majority of people live for less than US $100 per month.

In my opinion both. It has been posted on GNU website what is needed
in terms of critical software where GNU need help, but website is huge
and when there is complex information it may not be quite clear. In
terms of Emacs I do not know if GNU posted it anywhere but in
etc/TODO.

It would be good to make a list of items where Emacs need some help
including if there are some paid initiatives.

The free OS DragonflyBSD offers "Code Bounties"
https://www.dragonflybsd.org/docs/developer/Code_Bounties/ where some
people may say which feature they would like to see in Emacs and some
people program for the feature, so they could say US $100 within 6
months for the feature X to be programmed. We could use that as
example and I have proposed it before few weeks. There is no guarantee
offered that feature would be included even if programmed, developers
decide it ultimately. 

We could then all "bid" on various features or program for bidders
while improving free software.

That was a criticism on using weighting to account for missing data.  Weighting is
customarily used to reduce noise levels or as a sparsity constraint.  One possibility
would be a live survey (on the emacs website, a mailing list, ...).  Apologies if
the comment was too harsh.  The basic criticism has been that it favoured experienced
users.  Another way is to have multiple surveys based on emacs use experience, and then
normalise the results between the different experience levels.  In that way things
won't get skewed.

I would think that if there are competing views, we must not favour one or the other,
but consider them equally valid.  It would then be simply a question of priority or
perhaps measured on difficulty.  There is use for toolbars and should not be discounted.
Another way is to isolate functionality so those who want to use then can install a package.

Ultimately, it is for the maintainers and contributors to decide.  There are many books on
statistical inference.   A popular technique is to divide the data into groups followed by
a data representation strategy based on the most significant clusters.  One can also study
correlations between groups as being statistically significant.

Something that works like LibreOffice, where you can write a document,
select parts of it, mark them in bold, justify them, etc.  All of that
while you see the results in a WYSIWYG fashion.  The closest thing there
is now is enriched-mode, but that mode does not offer the same level of
features as LibreOffice.

There is more context about this potential new feature in /etc/TODO
under the section "Emacs as a word processor".

Data may be obtained with care, attention and skill and still be
misleading.

That there are good intentions with the survey, I have no doubts.

On how results were presented and how survey has been conducted I have
no doubt that author lacks the skill on the specific subject of making
an opinion poll. 

I have no doubts that author of the survey did conduct the survey,
connected websites together and made some marketing for people to
place their polls. And I have no doubt on his other skills,
programming, using mathematics, and I did not review the way of
counting, but I would not doubt on the manner of counting statistics
at this moment.

Emacs survey has a lot of misleading information that was already
mentioned here.

Major misleading information is the difference between general survey
and specific survey that relates to a subset of people from specific
groups of people.

Then we come here to discuss the toolbar that only a subset of people
from specific groups of people said something about that. I do not
agree that "any data is better than no data". The information may be
useful but due to its presentation it may be even more misleading than
useful.

When one says it is "Emacs Survey" I do not see it and do not
understand it by such general term.

As one may see on this picture of the survey in question this survey
represents 54.1% of people comming exclusively from Reddit and Hacker
News, then comes 7.8% Twitter. Majority of people 61.9% answering the
survey are groups coming from Reddit, Hacker news and Twitter users.
https://emacssurvey.org/2020/how-did-you-hear-about-this-survey.svg

Better would be to say that it is Emacs Survey that represents almost
62% of Emacs users coming from Reddit, Hacker News and Twitter.

One may see here that 1.4% of users answered the survey by email:
https://emacssurvey.org/2020/submissions-medium.svg

There are 7344 total responses.

1.4% of 7344 is 102+ users (more than 102 due to floating
point).

Maybe those users did not want to submit the online form as they did
not want to use non-free Javascript? But maybe those users did not
want to submit as they wanted to express themselves better by using
the Org file sent by email? We do not know why, but we can assume that
1.4% did not want to submit the form online.

We may compare data, we could take the Debian popularity contest:
https://qa.debian.org/popcon.php?package=popularity-contest
where recent data says that 200504 people installed the package
`popularity-contest' that counts which other packages are installed on
the system.

Then we may look into the subset of those 200504 Debian users who
installed Emacs: https://qa.debian.org/popcon.php?package=emacs

To me it looks like about 14,000 users installed Emacs on their Debian
GNU/Linux system. That amounts to some 6.98% of 200504 users who use
the Debian popularity contest package.

As Ubuntu comes from Debian GNU/Linux some vague information says
there are 20 million Ubuntu users.

If we would follow the trend of 6.98% let us truncated it to 6% of
people using Emacs on Debian derivative distribution, that would
amount already to (* 20000000 0.06) 1,200,000 people using Emacs in
Ubuntu. https://ubuntu.com/blog/ubuntu-is-everywhere maybe this number
is larger or bigger, but it does give some traces on how to conclude
how many people are using Emacs.

This page says there must be 100+ millions of GNU/Linux users on
Desktop (not counting Android):
https://www.quora.com/How-many-Linux-users-are-there-in-the-world/answer/Juha-Kaskiharju

but I cannot know where and how information has been obtained:
https://www.netmarketshare.com/linux-market-share

If we do assume there are 100+ millions GNU/Linux users who use their
browser as that is how companies detect such users and that 6.98%
trend as established from Debian popularity contest uses Emacs than
that may amount to 6-7 millions of Emacs users.

If we now come back to those 1.4% that did not want to answer the
survey by using non-free Javascript, maybe the real amount of those
people, who did not see the survey, but would not answer the WWW
survey for some of not unknown reasons, is already (* 6980000 0.014)
97720 users.

Emacs survey of 62% of Emacs users coming from Reddit, Hacker News and
Twitter has shown that that subset of users being about 4340 users
would gladly answer the survey over WWW form, with or without
considering if they use free or non-free Javascript.

I am personally, not by mathematical estimation, thinking that 90,000
of Emacs users and more than that, would not answer the survey only
because of the non-free Javascript or because how survey was
conducted.

Now let us say we discuss of toolbars, we do not discuss of toolbars
for Emacs users. We discuss of the fact that 85.1% of users using
Reddit, Stackexchange and Twitter who answered the Emacs survey that
relates to 62% to those groups are disabling the toolbar.

MacOS users from the Emacs survey are 26.6% plus Windos 7.4%, total
being 34% among all Emacs survey users or 34% from 7000 amounting to
some 2380 users.

When considering then if toolbar shall be disabled, shall we also
consider are we disabling it for majority of GNU/Linux users, or for
majority of proprietary system users, or for those Emacs users who
never answered the survey due to not unknown reasons which may amount
to almost 100,000 but which user habits we do not know.

In general the survey results would be much more useful would we have
intersections of people by various characteristics. We do not have
intersections, though it could be possible to make such intersections
with the data at hand.

Then survey did not give the result if users would like by default the
toolbar to be disabled. As when user disables the toolbar it does not
mean user would like it by default to be disabled upon first
installation.

The Emacs survey we speak about is not general Emacs survey.

That is in my opinion major misconception that people will get as it
all sounds so much official with nice and shiny charts.

It is Emacs survey that represents for 62% those users coming from
Reddit, Stackexchange, Twitter and we do not know many of intersection
results as such are not presented on the website.

If one only looks at one chart, like on chart among Emacs Survey
representing 62% users from Reddit, Stackexchange, Twitter, then one
may draw conclusions which are counter useful to the real number of
Emacs users.

What would be useful to know for development could be interesections
of:

- users using Windows, using Emacs with daemon mode
- users using MacOS, using Emacs with daemon mode
- users using GNU/Linux, using Emacs with daemon mode

- users using Windows, using Emacs as GUI or terminal
- users using MacOS, using Emacs as GUI or terminal
- users using GNU/Linux, using Emacs as GUI or terminal

- users using Windows, disabling toolbar
- users using MacOS, disabling toolbar
- users using GNU/Linux, disabling toolbar

then again intersections for menu bar, splash screen, etc.

Taking just one chart and looking how 85.1% users disabled toolbar is
incorrect interpretation that there is something to be handled as that
data comes from specific groups of people.

One cannot even ask experienced user if the tool bar should be
disabled as that is misleading. One could only ask a very new user who
has never seen Emacs, by placing that user on the chair and showing
him Emacs interface and then asking him if the toolbar is useful or
not useful.

Make that a first question to 10 people who never used Emacs and then
see the result and compare it. I guess that 10 people would be enough,
Nielssen says 5 people are enough, and I understand his methodology.

It is thus in my opinion more productive and more useful to take those
5 people or make 3 groups or 5 groups of 5 people and place them in
front of Emacs to tell us if they find toolbar useful.

It is counter productive to make assumptions to disable toolbar
because users who already used Emacs probably for years disabled the
toolbar. They are not new users.

While they may tell that disabled toolbar for them is good, they
cannot tell that for new users for which toolbar would be disabled by
default, they are not qualified for that as they are not new users any
more.

A built-in Emacs opinion poll sent by email in form of LISP data that
may be automatically evaluated would create better data on what people
wish and want, or what is more usable or not usable.

But even more usable would be simple Nielssen usability test:

I'm far from the only one who determines what developments are or will
be going on in Emacs.  Just look at "git log" and you will see that.

He said that about gud.el, which is nowadays obsolete, as far as its
GDB interface is concerned.  We leave its GDB parts in Emacs only
because in some rare cases using annotations works better with GDB
than using the MI interface.

It is customary for GNU projects to have a TODO file, and Emacs
follows suit.

The WYSIWYG part is missing.  See the etc/TODO entry about that for
a pointer to a discussion about this.

Could I then arrange translations to Swahili (Kenya, Tanzania, Uganda,
Congo) and Luganda (Uganda) for Emacs?

Is it possible to start, like using gettext stuff?

Personally I think Emacs is half-wysiwyg, or more then half by now. I
think there are almost all tools needed to implement a word processor a
lá Word already in Emacs; I think there is just some minor details
needed; like renderer that can draw efficient representation of a page
below a buffer text (a rectangle) and to tie the text editing stuff to
pixels rather then columns. I was experimenting with modelling a page in
Emacs in context of some other discussion, and that was what I found a
tad bit awkward.

But I am bad at Elisp, and what Emacs already has, so hopefully Eli will
step in and say: "we already have this."

To explain myself:

A word processor usually has some representation of page in paper
format. We can modell a page easily as a region; but it would take
work to implement text processing functions to work with "pages" (insert,
delete etc). It is not hard part, it is just labourous. Problem is when
presenting an empty page to the user to work with in Emacs windows. There is
need to draw some kind of rectangle representing page and user would
type in text above it. Emacs renderer has svg which can render
rectangles fast, but can it render below the buffer text? If it can then
you have everythign needed. I don't know how to do it though.

It is also a bit awkward to work with window-text-pixel-size and 
window-lines-pixel-dimensions because they need a text to being able to
calculate something. When buffer is empty, there is nothing to
calculate. There is need to tell Emacs: "I wish a buffer of this pixel
width and height". In some way. That is what I have seen as a problem,
but it is maybe possible, I am just not aware of funcionality I can use.

I have made a small demo, just roughly modelling a page. To overcome the
need for content in buffer in order to display something, the idea was to
insert "filler-spaces" so I could have something for renderer to
display. I ment to see if I can implement same behaviour as Emacs does
for invisible text: to restrict cursor motion into filler-spaces. But
I never come to that part. The idea was also to model columns, headers,
footers etc just regions in a buffer and to adjust insertion/deletion
routines for "page-mode" so cursor movement, and all the other editing
would look like in a word processor. For example deleteion would delete
a character but insert a filler-character, insertion would insert a
character but delete a filler-character and so on.

I think it is possible, it is just lots of labour I don't have time for
tht myself.

For illustration purpose I have attached the demo I worked on if anyone
would like to look at it, maybe continue or maybe just get an idea how
to implement it more efficiently. Paper size database has to be
evaluated forst, then page.el. It was just a small test I never got back
to, so take it just as a small illustration. Demo is font dependent so
with of the rendered page will depend on what font Emacs uses to
calculate (whatever is default). On my machine it is Anonymous Pro.

I think most of the necessary infrastructure exists indeed.  However,
building a WYSIWYG word processor on top of that is not a trivial job,
although probably not rocket science, either.  I'd start from
enriched.el and took it from there.

Yeah, I know; that is why I said it is not hard, but labourous. Yes I
was thinking of enriched mode, and some parts of org.

Rougier has made a very nice demo with svg-toolbars; those things could
be put together to create a kind of wysyvig where people can mark text,
set it to italics/bold etc. Justifying text could be done too. But
without being able to render a page representation in a buffer, it
wouldn't be feel of a word processor.

Maybe the feel is not that important; maybe it is enough to just render two
lines where page width and page height are, so user can adjust text
manually when he/she sees it go out of the "page range".

Printed preview could be achieved with svg renderer just rendering
buffer into an image of given page width and height. Would need to take
printer characteristics into account, but some basic print preview, not
pixel perfect could be achieved relatively easy.

Maybe you wanted this:

as white-white does not show anything.

(defface fill-face
  '((t :foreground "black" :background "white" :box "white" :height 100))
  "Default face for document background" :group 'doc)

?

It was just a test to modell a page .... it's not something you can
use. You can just create a document and insert a page. Nothing else is
implemented. 

But if you are interested to work on it, enjoy it :-).

The argument was to conrtol it better so things will stay within your reach.

Do you like it how it is?  Have heard you say that ultimately you have to
do work, and when you ask for help nobody comes forward.

This change might might be good in some ways, if the maintainers want
to do it -- but I'm not going to try twisting anyone's arm to make it happen.

LibreOffice doesn't ask that question, and it lets you start editing
text and knows what size to use by default for the page.
I suggest looking at what it does.

One interesting question is how to make text flow between pages.  In
Emacs, a page boundary is a ^L character (formfeed).  To make text
flow between pages would require deleting and inserting ^L characters
as needed.  Is that workable?

(I remember when ^L made the line printer skip to the next page.)

I don't follow that.  Could you give a concrete example and say
what these fillers would do, what benefit would result.
I think they would be a pain in the neck
for all the editing commands.

His meaning was not clear to me.  If there is no reason to think

Please, everyone, let's discuss this without getting angry at each other.
That is very important!  We have to _work together_ to use the answers.

The survey does not have a reprepresentative sample, but that doesn't
mean it is useless.  I wouldn't attach significance to its precise
numbers, but even the rough quantities have something to teach us.

For instance, we know that lots of users don't want the toolbars,
but a substantial fraction do not turn them off.

If we want more precise figures, I've suggested how to get them.
But I contend that we can come up with approaches that will
to a good job for the various kinds of users we know exist,
without needing to know the precise size of each kind.
We need to be clever and try lots of options.

People should not take offense on a description that defines how things
are.   When surveys are not representative of reality and we cannot attach
to them significance, it is disconcerting when the severe effects of that
are not being taken forward.

I remember criticising geologists interpreting seismic characteristics when
the geophysical image did not allow interpretations below a certain level of
resolution.  But they did that anyway.

A useful reading is "Command and Control: Nuclear Weapons, the Damascus Accident,
and the Illusion of Safety".  I am an adult living within the constraints
and responsibilities of society not a boy believing that everything is possible.

Fully agree with that - doing a good job for the various kinds of users
we know exist.

Somewhere under the hood in it's source code it does. :-)

I don't think you have understood what I ment there. Maybe I was too
flumsy when writing.

What I ment is that somewhere in the application code there have to be a
database of papersizes, so that application can draw that representation
of a page on the screen such as they do in Writer for example and how
wide lines will be so it can break lines properly, where user text would
start on those line, on the page, when to break to next page etc.

One annoyance is also renderer which in Emacs can't draw an "empty
buffer". Libre Office draws a white rectangle and some lines
around. Emacs can't do that since we can't draw things in layers, at
least what I am aware of (Mr. Eli? ).

Maybe that itself is not that desirable, and could be a "nice ot have "
feature but which can easily be lived without. As a poor man version,
one can just draw lines with unicode chars '|' where say width of page
ends for visual representation and simply insert ^L styled vid svg image
where page ends.

I think that would be conceptually trivial, but labourous as now, that
is what I tried to say in mail with demo I sent. I had idea the idea to
do in that demo, but I never got back to work more on it. 

Insertion routine would need to know where pages starts and ends. I
think a page can be modelled just as a range between two points (a
region). There are more details of course; printer margins have to be
taken account, headers, footers, client area and what not.

But roughly insertion, deletion and other text routines whichever they
are, would need to check if text in a page has reached to certain point
and if it is to insert ^L and reflow the page(s) as needed.

Yes, they would be pain, but all editing commands would have to be
changed anyway. There would be some document mode or wysiwyg mode or
whatever which would have to either overwrite or advise insertion,
deletion, etc.

Those filler spaces was my compensation for how Emacs buffer and renderer
works.

I had an idea to emulate visually a page as in a wyswyg editor. Emacs
can't render an empty buffer of certain size, not what I know. Maybe it
is possible to do something with child frames, or fringes or some other
trick, I don't know. But it was a compensation, I calculated a number of
columns with default font to fill a certain width in pixels. It is a
flawed approach, but it was just an experiment. So I insert just white
space characters which I call "filler space".

The idea was also to use them conceptually like spacers so I can tell
the insertion routine to really start from column X and not from first
char in line, and to break at column Y and not the last column.

I see page as consising of header, client and footer areas which are all
just ranges, so it really is just checking some integers; not very
hard. I also see those areas start at some margins (printer margins),
since printers can't print directly from the edge of the paper.

Also insertion deletion would have to take into account they work in a
page, header etc, so when character is inserted somewhere in a page, one
would have to delete a character at the end of page or rather client
area. But that would all be just a hierarchical delegation when it comes
to implementation.

Also since we are inserting in a buffer, inserting a char in first page
could potentially move all chars in a 100 pages long book. That is
probably now what we want. We just want to move text on that page. Filler
space was ment to be used there as spacer too. Insertion would delete a
space at the end of line or client area to make room for user character
so not entire Emacs buffer is moved around.

I also wanted to see if I can give them similar property as invisible
text in Emacs has; I wanted to restrict cursor to move into filler
space, but I never got to that part, so I don't know if it is possible.

It was just an experiment. If I remember, in demo I posted, one can
break page at arbitrary point and insert new ones. But what I noticed is
that it was very slow after few pages were added. Also there are other
problems, for example most important is how to calculate width of
columns to start with? Take a space character and see how many fit into
given pixel width? Or some average size? I took space for the
experiment, but it is not acceptable approach in general.

Maybe it is more effective to not visually model a page, but to just
render a line where line ends so user can see text has got out of page
width and can reflow things themselves. It could be cheap start at least
and probably not so hard to implement.

Texinfo does things that way.

I can print into PDF or Postscript and will get a different font then
on the screen. Good for me as I am fine with my printing, yet it does
not reach What You See Is What You Get paradigm. If I would record
screenshot, that would be only case to get what I see.

In the Org mode there is Title and Author keywords, so that is far far
from getting what you are seeing.

If we reach what LyX document processor has reached, the paradigm of
WYSIWYM or What You See Is What You Mean that would be already
enough. That could be reached already now if basic fonts such as
Courier, Roman, Sans Serif, can be mixed and they can
be.

I have used Lyx , but turned to Emacs as it was better to configure.
The WYSIWYG is good though.

Actually LyX is using WYSIWYM paradigm, like What You See Is What You
Mean. If I don't want to think much about formatting within Emacs, I
will use LyX, it offers me quicker LaTeX and other similar TeX based
templates.

After a while of work, after months or years, then I have those
LaTeX templates anyway on computer, so what I do is just open one
LaTeX template, rename it for new purpose, modify the text and insert
new text and voilà.

My largest problem with LyX is that I have to use X org based keyboard
bindings to switch between languages as I often use 2-3
languages. Switching the input method in Emacs is so much more
easier with C-\ and setting it up with C-RET-\

I may use Arabic keyboard with some weird hard to find English layout,
Emacs helps there. German input method on US layout, Emacs helps, and
so on.

I just wish other systems would have input methods that well defined.

I like vim and vi editors as well, but input methods are missing or I
do not know how to set it, so I have to use xmodmap.

I see the the C code of ngettext.

I hit a problem with WYSIWYG when trying to implement the WYG part for
emacs-pdf: My console emacs has black background but my paper is white.
Any ideas how to handle this use-case in WYSIWYG editor?

I do not have /etc/TODO file.  Is there an M-x command to open that TODO
file?

It doesn't matter if I like it or not if I cannot change it.  Whatever
I thought I could change I already did, or at least tried.

Not always and with any issue, but sometimes, yes.

Still, Emacs development is determined by many more people, which is a
Good Thing.

In emacs-pdf, I respect ^L and start a new page.  Additionally, a new
pdf page is automatically started when the page gets full (but this is
not indicated in the original text buffer).  It could probably be
feasible to indicate the additional computed page break in the original
text buffer but then there should be a concept of user-entered page
break (e.g. ^L) and computed page break (how to indicated that?).

Another problem with pages is that it requires user configuration (like
emacs has for postcript printing which could be reused) and whole
complexity of fonts and layout.  So far emacs-pdf handles ascii
monospace monochrome buffers only thus in a sense it is already WYSIWYG.
I get the same thing on the paper as on the screen (minus headers and
footers).

Should headers and footers be also displayed in the original text
buffer?  Should they be editable?  How should it be handled at the low
level, e.g. as a text property?

Another problem is inserting computed values, e.g. current page number
or total number of pages, which is often used in headers and footers.
This means that the whole rendering becomes a fixed-point computation.
In emacs-pdf, I simply process the whole document twice and assume that
the layout would not change further anymore but that is not a general
solution.

Emacs already has that.

This is what I use in emacs-pdf:

(defun pdf-page-dimensions ()
  "Return values of page width and height depending on
ps-paper-type and ps-landscape-mode."
  (let ((x (cdr (assq ps-paper-type ps-page-dimensions-database))))

I don't think I understand what you are saying, because you didn't
elaborate about the "white rectangle and some lines around" drawn by
LibreOffice.  Emacs _is_ capable of displaying an empty buffer, you
can easily see that for you self if you do "C-x b foobar RET".  And we
also have some decorations around the window and the frame, regardless
of whether or not there's text displayed there.

So I think the important question here is: what would we like/need to
display "around" an empty text area?  Armed with that knowledge, we
could discuss how to do that in Emacs (if we decide it's important
enough).

I also think that it is not wise to talk about page decorations before
we actually have a WYSIWYG editor that can display formatted text.
The decorations are secondary features, IMO, the perceived difficulty
in providing them shouldn't stop us from implementing "the meat" of
any word processor.

Exactly, the next 2021 year is good one to get some WYSIWYG features
and word processing in Emacs.

"Ready" in what sense?

There were serious discussions of this stuff in the past, which
revealed the parts of this (large) job, and in particular that just
having a Lisp binding for gettext is not enough.  We are "ready" in
the sense that someone needs to implement at least some of those
parts.

(This is about l10n; i18n is in Emacs since v20.1.)

A typo, sorry: it should be etc/TODO in the Emacs source tree.

Clever, I haven't thought about that.  Now I only need to find white
toner!

I'd say that when you render for printing you should always generate a
document with black text over a white background.  Unless the user
explicitly changes the face of parts of the text, in which case you
respect them.  That's not truly WYSIWYG, but seems like a sensible
approach to iterate on.

Yes, that's what I do at the moment and it works fine for monochrome
output.

But if the buffer has colored text and I do not want monochrome output,
how should those colors be chosen?  I do not think that swaping black
and white and keeping all other colors intact would give good results.
And I do not think there is a formula to reverse video colors, or is
there?

Can you give me a link to the dicussion?

So far as I can imagine, these problems should be solved before we
introduce l10n to Emacs.

1. Emacs should be able to compile gettext *.po file, not just read *.mo
file. It's not elegant to distribute package with *.mo files bundled.

2. More tightly integration to gettext tools. This may already be
solved, we can merge the po-mode.el from gettext project to Emacs and
improve it.

3. Namespace. In order to make all 3rd-party Emacs plugins to use
gettext l10n, we should provide a proper way to let plugins declare
their own text domain. And we may also need to resolve the conflict.
Since all plugins run with Emacs in same process. text domain name
confliction will be a big problem.

You probably don't, because I certainly wasn't talking about decorations 🙂.  Why would I do talk about decorations?

Yes, an Emacs buffers of course. I have seen it, 20 years now 🙂.

I don't know if I expressed myself badly, I don't remember what I said and I am often too fast to type; but I
was talking about visual feedback to user: so called what-you-see part
in wysiwyg. When I say white rectangle, or at least some lines or some notification
to user when he/she is typing outside buffer, it is not about "decorations" it is
about visual feedback what is going on. Otherwise it is not much of a wysiwyg, isn't it?

Yes, I agree; and sure that feedback can be minimal, for example, Emacs could simply prevent
user from typing after certain width, and insert just ^L after certain height, but some feedback
is needed. Emacs could just draw a line on the right edge with pipe characters as I mentioned
before; but having a nice background representation of a page in form of a rectangle and some
support lines to show where margins are would be much nicer and give more of a wysiwyg feel.

> And we also have some decorations around the window and the frame, regardless

Yes I know of course, but these are around frames and windows. Imagine an A4 page. It
would be nice if user have some visual cue where edges of the page start and end and so on.
Windows and frames can be resized, and they are buffer specific. A document can have many
pages. Users might also wish to resize window to show just part of the page maybe? I am not
sure how would you tie a window to page, but I am not so introduced to Emacs internals either.

I had thoughts to use a child frame to display a page and show just a part of a buffer in it, or to
use a buffer per page, but I don't think it is good idea. Maybe you see some other possibility.

> I also think that it is not wise to talk about page decorations before

You can already display formatted text. You have implemented it! Emacs draws italics, and bold, and superscripts,
different fonts and what not. It just has to be connected to a button! N. Rougier made awesome little svg library for
toolbars and now he posted little svg-icon library to download icons. It is justto create some nice svg buttons
and toolbars and connect it to those functions for text formatting.

Of course decorations are secondary, but visual feedback in a wysiwyg tool shouldn't be secondary; it is
not about decorations, it is about giving user feel and visual help to manipulate objects on the screen.

At least that was my thought 🙂.

Merry Christmass to all! <3

I don't think I understand what you are saying, because you didn't
elaborate about the "white rectangle and some lines around" drawn by
LibreOffice.  Emacs _is_ capable of displaying an empty buffer, you
can easily see that for you self if you do "C-x b foobar RET".  And we
also have some decorations around the window and the frame, regardless
of whether or not there's text displayed there.

So I think the important question here is: what would we like/need to
display "around" an empty text area?  Armed with that knowledge, we
could discuss how to do that in Emacs (if we decide it's important
enough).

I also think that it is not wise to talk about page decorations before
we actually have a WYSIWYG editor that can display formatted text.
The decorations are secondary features, IMO, the perceived difficulty
in providing them shouldn't stop us from implementing "the meat" of
any word processor.

I think it would be really great if we could reshape our development
community into something more like a team.  But that is easier said
than done.  The first prerequisite is that the people in question
want to become a team.

I have the feeling that a task important enough to be worth offering a
reward for are likely to take over 100 days.  So that still means 1000
or 2000 dollars.

That is fine for some jobs, but not adequate for writing text to fit
in one or two sides of a sheet of paper.  For that I have to use
LibreOffice -- and I always wish it had the Emacs editing facilities.

I understand what you mean.  Whan I want to print something quick,
I also have to turn to LibreOffice.  I wrangled that a new major mode
could suffice, but I am not an knowledgeable enough to be sure.

Really? I left it long ago, I wish I would have some use of
Libreoffice, but don't. Everything I do in Emacs.

For simple printing of text I use Emacs with these commands below to
create PDF files. Then I get those outputs as in attachment. I could
make some function and enlarge or make letters smaller or change
output fonts and so on.

(setq ps-bottom-margin 40)
(setq ps-header-offset 20)
(setq ps-lpr-command "ps-print.sh")
(setq ps-print-footer t)
(setq ps-top-margin 100)
(setq lpr-command "paps_print.sh")

ps-print.sh:

#!/bin/bash
tmpdir=/home/data1/protected/tmp/muttprint/
mkdir -p $tmpdir
cd $tmpdir
file=$tmpdir/$(date +'%F-%T-%A')

It is something we really lack and a transition that would elevate us to a new level.
It is difficult because we would need to work in a more disciplined way.  It's all
about focusing on the process rather than the target.  Most times, the best results
are achieved by doing what's best for oneself and the group.  The idea of mixed-strategy
equilibria and its proof started by John Neumann in 1944.

Then, we can allow people to donate/vote for specific tasks and
important tasks should be able to get that much fund (I imagine).
2000USD is 200 people donating 10USD. I guess that really important
tasks are the tasks that are wanted by several hundreds of people at
least.

They are easy enough to find: search the list archives for "gettext"
or "l10n", and you will find them.  The last one starts here:

These are technical problems that can be solved relatively easily.
The real issues are much harder, as discussed in those threads.

Those things we "just" have to do, must be done, otherwise we cannot
claim to be anywhere near a word processor, because it is unimaginable
in a word processor to apply faces via Edit->Text Properties, let
alone via lower-level commands.

And the next thing to do is the ability to save all that face
information to a disk file, so that the next time you visit the file
you see the same faces.  Enriched mode does that, but it needs more
love.

Next after that is pixel-level indentation and filling/justification,
so that we could use variable-pitch fonts.

Next are the printing facilities, where I hope we will once and for
all solve the problem of printing non-ASCII, non-Latin-1 characters.

When we have done all that, we will have a significant portion of a
word processor, IMO.

I concur.  That's a fair amount of basic stuff
to provide, as stepping stones.  And each bit
of it would be useful in its own right and for
other purposes as well.
___

Wrt "it is unimaginable in a word processor to
apply faces via Edit->Text Properties", FWIW:

Some of my code can help with on-demand, ad
hoc highlighting.  And yes, it's on Edit >
Text Properties.  But it could be put on
tool-bar buttons or whatever.  And of course
other implementations of such basic features
are possible, and would no doubt be chosen to
provide performance as the basis of low-level,
built-in word-processing.
___

Examples:

Apply a color or face by dragging the mouse
like a highlighter pen:

1. Edit > Text Properties > Highlight >
   Highlighter Pen
2. Drag mouse to highlight text dragged over.

Apply a color or face to a selection (region):

1. Select text.
2. Right-click `mouse-3' twice (slower than a
   double-click).
3. Choose Highlight > Highlight in the popup
   menu.

Apply a color or face to a symbol at point:

1. Right-click `mouse-3' twice (slower than a
   double-click).
2. Choose Thing At Pointer > Highlight Symbol
   in the popup menu.

Do the same, but using hi-lock (highlight all
occurrences of the symbol):

1. Same.
2. Choose Thing At Pointer > Hi-Lock Symbol
   in the popup menu.

Choose a color or face to use for all such
highlighting operations (and others):

1. Edit > Text Properties > Highlight >
   Choose Highlighting Face
2. Choose a color or a face (for background)
   using completion.

Critical to choosing a color or face is the
ability to see a sample associated with its
name (the completion candidate).

There are several pieces that combine to
provide such behavior.  Of course things could
be done (implemented or organized) differently.
I'm just pointing out some pieces as food for
thought.

1. For showing samples along with color and face
name completion candidates, i.e., WYSIWYG, I use
Icicles.  (Icicles lets you match RGB hex codes
as well as color names.)  I imagine that some
other completion frameworks offer something
similar, or could do so.

Screenshots:

https://www.emacswiki.org/emacs/Icicles_-_Screenshots#icicle-read-color

(I also have library `palette.el', which gives
you a complete color picker, and library
`eyedropper.el', which just picks the foreground
or background color at cursor or pointer.  Some
of the display quality of `palette.el' has been
degraded by changes to Emacs, and I haven't kept
up with fixing that, but it still works.)

https://www.emacswiki.org/emacs/ColorPalette

https://www.emacswiki.org/emacs/download/eyedropper.el

2. For highlighting by dragging the mouse, and
for choosing a color/face for that, I use
library `highlight.el'.

https://www.emacswiki.org/emacs/HighlightLibrary

3. For putting that on a Highlight menu under
Edit > Text Properties I use `facemenu+.el'.

https://www.emacswiki.org/emacs/FaceMenuPlus

4. For highlighting on a `mouse-3' popup menu I
use library `mouse3.el'.

https://www.emacswiki.org/emacs/Mouse3

This is equivalent to deciding to consider white-on-black to be a mode
of display rather than a property of the document.  I think it makes
sense.

It is trivial for monochromatic documents.  The question is: What should
happen if there was another third color in the document?  Should that
third color stay the same on black display and white paper?  Emacs kind
of solves this for display by manually defining faces for each use-case
(black or white background).  But is there a better, automatic way
suitable for printing?  Or maybe the buffer should simply use the same
background as paper?  Is it possible to reverse reverse-video per
buffer?

Actually, not even: if you've ever looked at the "negatives" used for
analog black&white photos you'll surely understand that inverse-video
doesn't work so well for images (mostly because it inverses lights and
shadows, thus confusing the semantics).

For a "pure" text or other such circumstances where the colors don't
carry much meaning, it's not too hard to do something like "inverse
video" with an acceptable result, but for photos or comparable kinds of
images, I suspect that it's somewhere between very hard and impossible.

Ok, I did not mean gray-scale.  I meant text in black ink on white paper
WYSIWYG edited in Emacs with reverse video colors.  I cannot recall the
proper name for it at the moment but you get the idea.

Now add third color, e.g. to highlight a word in the document.  Simply
swapping background and foreground color can make the highlighted word
badly readable, if the color stays the same.

We can leave photos and images out of the question and simply preserve
their colors.

Do you have suggestion for automatically computing "it's not too hard"
color mapping for "inverse video" "pure" text?

Convert the color's YUV and invert the Y.

Possibly better: keep the hue and saturation and recalculate luminance
to preserve the relative contrast to background color.

There are lots of ways to "invert" or complement a color.

I just use RGB complementing - good enough for most
purposes for Emacs foregrounds and backgrounds.  Function
`color-complement' in color.el does that.  So does
`hexrgb-complement' in hexrgb.el.

Or I use `hexrgb-hue-complement',
`hexrgb-saturation-complement', or `hexrgb-value-complement'
If I just want to complement one of those components.

My personal opinion is that gettext is too limited. It works for simple
things, but provides no help at all for complex things.

I think that the most productive way to think about translation is that
each coherent message that we present to a user (whether it's via the
message function or not) should explicitly be the result of calling a
function written by the translator. gettext only allows the translator
to supply strings, so it falls down in complex situations.

The classical example is the "You have 42 new messages." situation. With
gettext, it is tempting to ask the translator to translate a string such
as "You have %d new messages.", but this does not give them any
flexibility to correctly handle languages with more plural categories
than English. Russian, for example, has a plural category for all
numbers that are one more than a multiple of ten except 11, which is a
special case. It also has another category for all numbers ending in 2,
3, or 4 except for 12, 13, and 14. (I don't actually know Russian, but
the rules are summarized in a page or two at
<http://www.russianlessons.net/lessons/lesson11_main.php>.) There are
over 7,700 distinct languages in the world, and we should assume that
they are all at least that crazy. An ideal situation does not allow the
craziness to leave the translation and make the implementation more
complex. Nor should the craziness of Russian make writing a Spanish
translation more difficult.

Thus, each translation should provide a package full of functions rather
than a file full of strings. It could literally be that simple, though I
think that there are benefits to not making translators actually write
an elisp package. For one thing, putting the wrong kind of function in a
translation package could actually break Emacs (because there's no
namespacing). I think that we could compile these functions from a
different source representation, and that we could benefit from sharing
code and tools with an existing translation project.

I recommend taking a look at Project Fluent
<https://www.projectfluent.org/>. It's a free-software implementation of
exactly the system that I've described. Translators write functions in a
syntax that is similar in some ways to both Javascript and an ini file,
which could be easily compiled into Elisp. (It's the successor to the
l20n project, which you might also have heard of.)

The Project Fluent webpage has an set of interactive examples which are
worth checking out.

I'd be willing to spend some free time to help implement this.

My feeling is that Emacs is so far from those problems that considering
such issues will do little more than delay any actual progress.

Possibly, but I'm not so sure. Just looking at the message function for
a moment (because it's easy to grep for), there are a nonzero number
that do numeric substitions. Here are a few selected examples:

    ./lisp/sort.el:638:      (message "Deleted %d %sduplicate line%s%s"
    ./lisp/calendar/cal-hebrew.el:188:  (message "Hebrew date (until sunset): %s"
    ./lisp/ido.el:1670:    (message "Ido mode %s" (if ido-mode "enabled" "disabled"))))
    ./lisp/calendar/appt.el:716:          (message "Appointment reminders enabled%s"
    ./lisp/calendar/icalendar.el:2287:                 (message "Cannot handle COUNT attribute for `%s' events."
    ./lisp/calendar/calendar.el:2040:    (message "Region has %d day%s (inclusive)"
    ./lisp/calendar/todo-mode.el:725:		       (message "There is no %s file for %s"
    ./lisp/calendar/todo-mode.el:5672:    (when prompt (message "Press a key (so far `%s'): %s" keys-so-far prompt))
    ./lisp/calendar/todo-mode.el:5772:	(message (concat "File" (if pl "s" "") " %s ha" (if pl "ve" "s")
    ./lisp/registry.el:317:	     (message "reindexing: %d of %d (%.2f%%)"

The one from todo-mode.el:5772 is quite interesting; you can see that
it's complex because it's handling English plurals. That complexity
would be moved into the English translation and out of todo-mode.el
entirely. The ones with colons are a way to make the substitution more
generic across languages by making plurals less necessary at the cost of
being more stilted.

You're missing my point: last I checked, we have 0 translations (well,
beside the tutorials, that is).  So, worrying about addressing the
plurality of plurals better than most other programs doesn't seem right.

Ah, ok. I suppose that's true. However, imagine the scenario in five
years when we have to rip out gettext and 42 translations and replace
them with something else because everyone is getting annoyed at how hard
it is to pluralize things correctly.

I don't think it will be all that difficult to do correctly, and if it
costs us a few months up front then in the long run that will be time
well-spent.

Daniel Brooks <db48x@db48x.net> writes:

> Thus, each translation should provide a package full of functions rather

As a concrete example of what I see in my head when I talk about this,
here's some code that generates a moderately complex message, which I
have taken from todo-mode.el:

    (let ((pl (> (length deleted) 1))
          (names (mapconcat (lambda (f) (concat "\"" f "\"")) deleted ", ")))
      (message (concat "File" (if pl "s" "") " %s ha" (if pl "ve" "s")
                       " been deleted and removed from\n"
                       "the list of category completion files")
               names))

I think that the best way to factor this code is this:

    (message (todo-msg-delete-from-category-completion-files deleted))

Basically, todo-msg-delete-from-category-completion-files is a new
function which bundles up all the work of creating the message to be
displayed. We pass it the list of deleted files, and it inspects the
user's preferences and does all the rest of the work. The naming scheme
is just what I came up with on the fly; it seems to me that it would
work, but it's a detail we should work out.

An obvious implementation of this function is this:

    (defun todo-msg-delete-from-category-completion-files (names)
        (let ((name (intern (concat "todo-msg-delete-from-category-completion-files-"
                                    (current-language-preference)))))
          (if (fboundp name)
              (funcall name names)
            (todo-msg-delete-from-category-completion-files-eng names))))

It just dispatches based on the user's currently-chosen language. The
function it dispatches to does the work of building or choosing a string
to return.  In those cases where we write code that should show a
message that is _not_ in the user's preferred language, we would call
the correct function ourselves. A good example of that would be the UI
that allows the user to choose a preferred language.

This could be included in todo-mode.el directly, but since todo-mode has
many messages to display, we would obviously want some macro for
declaring them in bulk. (That's another detail to be worked out.)

    (defun todo-msg-delete-from-category-completion-files-eng (names)
        (let ((category (plural-category-eng (length names)))
              (names (quoted-comma-sep names)))
          (format
           (cond ((eq :one category)
                  "File %s has been deleted and removed from\n the list of category completion files")
                 ((eq :other category)
                  "Files %s have been deleted and removed from\n the list of category completion files"))
           names)))

This is the one that does the real work. It chooses which string to use
based on the plural category (there are obviously briefer ways to write
this, but I wrote it this way for effect). It substitutes in the list of
files the normal way because english doesn't make us do anything odd for
that. (It would be nice if the formatted list had an "and" before the
final item though.)

This code could be written by hand with no trouble, and a translator who
knows Elisp could come in and supply a new group of functions that
implement the same interface but for their own language.

If we did the additional work of writing a Fluent→Elisp compiler, we
could write the same function something like this:

    delete-from-category-completion-files = { $names ->
        [one] File { quoted-comma-sep($names) } has been deleted and removed from\n the list of category completion files
       *[other] Files { quoted-comma-sep($names) } have been deleted and removed from\n the list of category completion files
    }

This is rather more succinct, and possible to teach to translators
without having to teach them all of elisp. We can compile this to Elisp
at build time, but I'd like to be able to load them dynamically as well.

The helper functions are all fairly obvious, and obviously incomplete:

    (defun plural-category-eng (count)
      (cond ((= count 1) :one)
            (t :other)))

    (defun current-language-preference ()
      "eng")

    (defun quoted-comma-sep (list)
      (mapconcat (lambda (f) (concat "\"" f "\"")) list ", "))

The current language preference could be a cusomizable variable, or some
other mechanism (a fallback to the LANG variable, for instance).

Each translation would have something like the quoted-comma-sep
function, though they might not all call it the same thing. This would
allow each translator to choose the most appropriate type of quotation
characters, list separators, conjunctions, and so on for the translation
that they are writing.

I think that all of this is doable in a reasonable amount of time, if
two or three people are working on it together. The broader work of
actually factoring messages out of the code and into translatable
functions would need to be spread out more broadly, but it could happen
over a longer period of time. It's a task of Herculean proportions, and
there is no conveniently-located river that we can divert.

It occurs to me that I haven't considered messages generated by C code
at all; I hope that they are few and far between, and that we can just
call back into lisp to generate those messages. There are bound to be
some messages that we just never end up translating.

The advantage of the translation infrastructure based on gettext is
that the translators don't have to be programmers, they only need to
be experts in correct use of technical terminology in their
languages.  Even with that significant advantage, it is hard to find
translators for many languages.  Your suggestion would make that job
much harder, with the net result that more messages for more programs
will remain untranslated: a classic example where the best is a sworn
enemy of the good.

(Disclosure: I'm the team leader for translators to the Hebrew
language, as part of the GNU Translation Project.  I'm talking from
personal experience here.)

This problem was solved in gettext long ago, and is being widely used
in existing translations.  See the node "Plural Forms" in the GNU
gettext manual.  Emacs has the ngettext function in preparation for
the day when we will be able to have translatable message strings.

How many translated languages for how many programs does this project
have?

Anyway, the hard problems in translating some of the Emacs UI are
elsewhere, as can be seen from the discussions to which I pointed.  We
need to solve those first, and only after that worry about the issues
you mention (if they are real).

Thanks for pointing this out.  I've now fixed this and other similar
places in todo-mode.el on the master branch by using 'ngettext'.  The

Before you set out to reinvent wheels, you should check what's out
there. The ngettext interface [1], which _is_ part of the gettext
package, addresses (even multiple!) plural forms, i.e. your Slavic
example.

Thing is, human languages are messy. You won't get everything covered.
And the more elaborate you get, the more difficult it'll be to find
translators having the time to grok all that complexity.

One of the nice things about this simplistic string -> string approach
is that it allows "lightweight" distributed translation approaches,
often web-based: those allow people to contribute translations to a
project who otherwise wouldn't even dream of contributing.

There are even platforms out there where you can register your Free
Software project and where people can contribute translations, via
a Web interface.

As always, it's a tradeoff.

On a different note, there are 725 matches for "> (length" in Emacs.
Computing length first and then comparing the number of items is very
inefficient.  There is a room for speed up here.  I wonder if there is a
way to prevent programers to do such inefficient things?

Yes, the simplicity of gettext is a big point in its favor. In the
common case, Fluent is not much more complicated. Here's a file from the
en-US locale from Firefox:
https://searchfox.org/mozilla-central/source/browser/locales/en-US/browser/aboutDialog.ftl

Most of the complications here come from the html that is embedded
inside the localized text:

    update-failed-main = Update failed. <a data-l10n-name="failed-link-main">Download the latest version</a>

Another language might put different text before or after the link, so
the anchor tag has to be part of the localized text. However, the
Javascript that displays this text will add the href to the anchor
first.

Yes, I am aware of ngettext, and I could have picked a different
example. Consider the example from projectfluent.org, where the output
should change based on the user's gender:

    shared-photos =
        {$userName} {$photoCount ->
            [one] added a new photo
           *[other] added {$photoCount} new photos
        } to {$userGender ->
            [male] his stream
            [female] her stream
           *[other] their stream
        }.

This one produces messages like "Anne⁩ ⁨added ⁨3⁩ new photos⁩ to ⁨her
stream⁩.", which vary based on the three inputs passed in. ngettext
handles plurals, but it doesn't generalize to any other type of
variation we might want. I can't think of any reason why Emacs would
care about gender, but maybe BBDB could.

Another example from fluentproject.org illustrates that individual
translations can add variations that are purely for their own use.

The English translation has "-sync-brand-name = Firefox Account", which
is just assigning static text to a variable which will use used
frequently.

The Italian translation changes it to this:

    -sync-brand-name = {$first ->
       *[uppercase] Account Firefox
        [lowercase] account Firefox
    }

which serves the same purpose but lets the translator put this text at
both the beginning and end of a sentence.

Meanwhile, the Polish translator has changed it to this:

    -sync-brand-name = {$case ->
       *[nominative] Konto Firefox
        [genitive] Konta Firefox
        [accusative] Kontem Firefox
    }

which lets them choose the correct declension when needed:

    sync-signedout-title = Zaloguj do {-sync-brand-name(case: "genitive")}

All three translations can do their own thing, without needing to ask
the UI implementer to change anything and without coordinating with each
other first. They can also add these features gradually, as they refine
the translation. For example, they can start with a form that partly
dodges the grammar like "New emails: 42" at first, then later refine it
to "Found 42 new emails" once they get better coverage.

The main one that I know of is Firefox, which by my count has 96
translations. (See
<https://www.mozilla.org/en-US/firefox/all/#product-desktop-release>.)

I think that a system like Fluent moves most of the problems into the
translations, where they are more tractable (because each translation
only has to solve it's own problems). Note that most of Firefox's
translations are maintained by voluteers. They don't even have to send
patches or commit files to version control; they use a web page to view
and edit the translation, as well as to preview the results live. The
same tools can be used for Emacs.

I will continue to peruse these previous threads that you've pointed
out, but I'm not aware of anything that would be harder than just going
through the code factoring out the text. There aren't any clever macros
that can help with that, just hard work.

What did you have in mind that would be more efficient?

The above code sets 'pl' to a simple boolean based on whether

(not (null (cdr deleted))) would avoid traversing the entire list, but it
wouldn't be easier to read.

I think this issue is largely irrelevant to Emacs (and to translating
program messages in general), since it customary nowadays to avoid
gender-specific language.  We certainly do that in Emacs.

I didn't mean one program, I meant the total count.  It should be
indicative to how easy it is to find people who are both programmers
and can succinctly express themselves on technical issues in their
native languages.  IME, it is very hard to find such people.

Perhaps a `longer-than-p' function would be helpful?  I.e.,
(longer-than-p deleted 1)?  (Or some better name.)

Agreed, which is why I went on with the other example. The main point is
that it is generalizable to other kinds of variation besides just
plurals. Gettext does plurals, but nothing else.

I don't know the full count, I only know that Mozilla uses it for
Firefox as well as all of their web pages, and that most of those
translations are maintained by volunteers. Those volunteers are clearly
capable of doing the job, since there are 96 actively-maintained
translations for Firefox, which is a complex application which is hard
to translate. I think we can find similarly-capable volunteers to help
translate Emacs once the infrastructure is in place. I don't think most
of those people will already know either gettext or fluent
syntax. They'll learn as they go, just like the rest of us do.

Being able to program for one project in that project's programming
language doesn't mean the same people can do that for another project
written in a different PL.  That's the main disadvantage of your
proposal: you require the translators to be proficient as programmers
in the project's PL, not just in their language.

Just curious: Does 'fluent' support (E)lisp and/or Scheme?

Just add an optional arg LIMIT to 'length', since the implementation
will be the same, and you just want to terminate the loop as early as
possible.

In many languages nouns have its gender classes, and I hope you do not
mean that. Example is that flower in German is refered as female while
in some other languages as male.

No, it would require no knowledge of Elisp at all. Learning Fluent isn't
going to be any more difficult than learning gettext; the simple cases
are actually simpler in Fluent, and the complex cases (handling
variations) is much simpler in Fluent than in gettext.

I would still define functions with specific names like longer-than-p
which have names that specify their exact meaning, even if they just
call length with extra arguments.

Not specifically. I envision having a simple compiler written in elisp
that turns fluent into elisp functions, or some other form that can be
loaded when needed.

The example I used was dealing with the gender of a user, rather than of
a random noun. Emacs itself doesn't talk about the user very much,
though in principle I could see someone using BBDB to keep track of the
gender of their contacts. Regardless, Fluent can handle either type of
linguistic gender with equal ease, as well as all other types of variation.

That is very terse, and I am not sure what it means in concrete terms.

That could be acceptable if it is designed such that the functions
are so limited that there are no insecurities.

For GNU to use it, we would want it to fit into the framework
of gettext.  We could have a new function that programs should call,
which would look for a function encoded in the translation string.

Would you please email me the most important parts of the description
of Project Fluent?  So I don't have to hunt for them?

I don't see how this is relevant to the issue at hand.  If I'm missing
something, please tell what that is.

That's a good point. The Fluent "language" does only string
substitution, switch statements that choose amongst a set of strings,
and calling functions pre-defined by the program being translated. That
makes it easy to compile into safe code, or to produce a database that
can interpreted quickly.

I haven't considered that possibility, but my first impression is that
mashing them together might not be a good idea.

> Would you please email me the most important parts of the description

Sure. The blurb on the FLuent website says this:

* Asymmetric Localization
  Natural-sounding translations with genders[1] and grammatical cases
  only when necessary. Expressiveness is not limited by the grammar of
  the source language.

* Progressive Enhancement
  Translations are isolated; locale-specific logic doesn't leak to other
  locales. Authors can iteratively improve translations without impact
  on other languages.

* Fully-Featured
  Date, time, and number formatting. Plural categories. Bidirectionality
  support. Custom formatters. Easy-to-read syntax. Runtime translation
  and re-translation. Robust error handling.

* Open Source
  Fluent Syntax 1.0 was released in April 2019. Client- and server-side
  implementations in JS, Python, and Rust. React bindings. Licensed
  under the Apache 2.0 License[2].

[1]: This includes both the genders of people and the genders of random
nouns in the translation. It also handles other sources of variation
such as plurals, declensions, inflections, and so on.

[2]: Aka, it's Free Software too.

Do you mean to teach computer to recognize gender of the user by the
user's name? That would not be a good guess.

What is possible is to let the user specify the gender and then
computer may construct gender relevant sentences.

Those titles such as Mrs. Mr. Ms. are more social titles, I use them
to recognie the social titles of people, but I do not consider them
equal to gender.

The only reasonable recognition of gender would be in a medical
database where people need to know something about that, or in dating
terms when one wish to mate with specific gender. Otherwise is more or
less useless.

What about length= length/= length< length<= length> length>=

No, no. Go back and look at the example I used; the user's gender was an
input. The user in that example has chosen their own gender, and the
translation can use that to output the grammatically correct
sentence. As I said, it's not super relevant to Emacs. I only included
it to show that Fluent handles all variations the same way, whether it's
plurals or gender or declension.

Reasonable suggestions, but not in my opinion as readable as
`longer-than-p', `shorter-than-p', and so on.

the first two don't need anything new, the rest can be handled with
the single argument I proposed and a negation function (which we
already have).  Right?

What I meant is something similar to kickstarter/indiegogo crowdfunding
model. Instead of donating to generic Emacs development, the users may
be given an option to give donation for a specific task. The accumulated
donations will be used to reward the contributors who close the task.
(There might be issues about splitting the reward if several people
contribute to the same task, but I believe that it can be worked out by
setting appropriate policies).

I think the similar idea is used in https://bountify.co/, judging from
their front page.

Best,
Ihor

Sure, as a practical matter, adding an optional LIMIT to length is
probably the way to implement this.  But I think adding some predicates
(like the length< etc predicated proposed by Tomas) as wrappers around
calls to length with LIMIT makes sense for code readability.

Actually...  looking a Flength, perhaps not adding an optional parameter
would be better.  I mean, the only type that's not constant in time is
the length of lists, so I think perhaps it would just be confusing.

Adding length=, length< and length> (as C functions) seems pretty
trivial -- punt to Flength for anything that's not a list, and handle
lists specially.  Those would have clear semantics, be fast, not make
Flength calls any slower, and not add more complicated semantics to
Flength.

I agree that adding an arg to `length` is probably not a good idea.

But how serious is this need we're talking about?
I mean we can already easily implement those things in ELisp:

    (defun length> (x n)
      "Non-nil if length of X is greater than N."
      (if (consp x)
          (nthcdr n x)
        (> (length x) n)))

Oh, sure.  But since this is a pure speed optimisation we're talking
about, the Lisp solution would be slower than the (< (length foo) bar)
in a significant number of cases, and we don't want that, do we?

(Most lists in Emacs are very short.)

Actually, AFAICT this all started from:

    (not (null (cdr deleted))) would avoid traversing the entire list,
    but it wouldn't be easier to read.

which doesn't actually demonstrate a need for "speed optimisation", but
rather a need to avoid extra work (which could lead to real performance
problems when the list is long), so the ELisp implementation seems to
fit the bill ("avoid traversing the entire list" while being "easier to
read").

Well, it started from (< (length list) ...), and the not-null-cdr was
mooted as a faster, but less readable solution.

A Lisp function would be slower (in many cases), but more readable.

I'm proposing a solution that's faster, and more readable.

I whipped one up quickly.  The slightly interesting thing here is that
we have an opportunity here to make this slightly faster -- since we
have an upper length bound here, we can eschew the tortoise/hare
FOR_EACH_TAIL bit and just follow CDRs, which would be faster.  Of
course, if you give it a circular list, then it'll always return Qnil,
and if you give it (expt most-positive-fixnum most-positive-fixnum) on a
circular list, it'll take a while...

With this totally realistic benchmark, this is what we have today:

(let ((list (make-list 10000 nil)))
  (benchmark-run 1000000 (< (length list) 2)))
=> (10.826215101 0 0.0)

The same, with length<:

(let ((list (make-list 10000 nil)))
  (benchmark-run 1000000 (length< list 2)))
=> (0.05590014099999999 0 0.0)

If we avoid tortoise/hare for small LENGTHs, then it's about 20% faster
than that again (if we're doing (length< list 200)).

The argument for adding this functionality was performance.  So
implementing that in Lisp would mean we don't need to implement it at
all.

No, it started from

  (> (length LIST) 1)

being a waste of cycles.

I can't believe this thread is going on & on about this.

Users need _anyway_ to learn that `length' traverses the
entire list.  And it's not the only function that does so.
This is part of learning Lisp (and not just Lisp).

All of your machinations to create additional functions
to "help" users avoid the gotcha of using `length' when
it's not needed won't really help, is my guess.

With that "solution" you've only added a new problem: you
now need to advertise the new functions and advise users
to use them, not `length', in such a use case.  Which
means you still have the need to identify the relevant use
cases, which means teach them about the `length' gotcha
(or hope they follow advice without understanding).  IOW,
now you have 2 problems...

This seems like a classic case of going against Occam's,
Razor, i.e., a case of multiplying things needlessly.
___

[Personally, in the case considered, I'd use (cdr x).
I wouldn't use (not (null (cdr x))).  And it doesn't
get simpler _or clearer_ than that, IMO.]

Users certainly do need to know the performance cost of the functions
that they use. But they also need alternatives. If (> (length list) n)
is a trap for new players, then document it as so _and_ mention that
there is a specific function that can be used to avoid the trap. But
it's also worth mentioning that maybe the code should use a vector
instead of a list, if the length is so important.

Also, as was pointed out, this very thing happens 735 times in the Emacs
lisp codebase. Probably most of those have no great performance impact,
but it's a good observation.

True. It's not the first time I've noticed myself making something more
complicated by eagerly converting to a boolean. But I still don't think
that it's readable code.

I spoke to that (e.g. doc guidance) a bit already:

https://lists.gnu.org/archive/html/emacs-devel/2020-12/msg01757.html

And as I said, `length' is not so special in this regard.
`map', `dolist', and others also provide the same rope to
hang yourself with.

Learning to `throw' out of a list traversal (or whatever)
when you can tell it's time to quit is a _general_
solution/idiom - good to know about even if it's not
always the most appropriate.  That should be taught in
the manuals (in this general don't-continue-needlessly
context), even if many prefer things like `cl-loop'.

There are no specific functions that can be used to avoid
the trap.  Not in general.  Code that DTRT in any given
context can be short, sweet, and clear.  I see no help
offered by `length<' & compagnie.

And if the list in question is short, and the context is
not performance-critical (e.g. tight loop that's important),
then there may be no reason to bother about not traversing
it entirely.  IOW, this stuff is best considered case by
case.  Lisp already has all that's needed to create clear
code that does what one wants AND conveys to human readers
what's done and why.

If a given case has no performance impact, then it's
maybe better NOT to provide code that might give the
impression that we're trying to avoid a particular
performance penalty.  Of course in middle cases, which
might not be obvious to a human reader, we may need to
make things clear explicitly.

I wouldn't be in favor of systematically avoiding use
of `length', as if all uses are poisonous.  That would
almost be akin to wrapping all uses of `dolist' in a
`catch'.  It sends human readers the wrong message.
When it's important to avoid traversing more than
necessary, make that clear.  Avoiding it _always_ makes
it less clear when it's actually needed, not more.

(Just one opinion.)

It is a mistake to make such specific assumptions about what we
will do, years from now.  We could do other things, such as.

* Not bother about it, because only a minority of users experience
a problem and it is merely the same annoyance they see in other programs.

* Fix it in gettext, for all GNU programs at once.

That is a reasonable way to speed it up.
But if this is mainly to be used in connection with
user output, the speedup would be insignificant,
and thus not worth the cost of documenting it
and maintaining it.

One of the basic design guides of Emacs Lisp is rejection of
the idea of adding more functions in the name of symmetry.

If there is a use for longer-than-p, or length> we could call it,
it may be worth adding that function, but let's skip the other 5
if they are not actually needed.

I think the idea of integrating Fluent with gettext is interesting.
Would you like to study that possibility?

It seems that Fluent is not self-contained but rather depends
on the presence of an interpreter for JS, Python, or Rust.
Is that correct?  That would be very undesirable in C programs
that don't contain any interpreter (and don't need one).

Is it feasible to write a small Fluent interpreter in C for this
purpose?

That is much harder than it seems.  But this list is not the place to

Richard Stallman <rms@gnu.org> writes:

Yes, I have been considering it.

The biggest disconnect between Fluent and gettext is that Fluent allows
recursive substitutions and multiple substitutions per message. Even
just the fact that fluent handles the substitutions itself instead of
making the caller delegate to printf is a big difference. Each message
needs to give names to the values that will be substituted into it
(basically argument names), and the PO files would have to specify how
to use those arguments, whether it's subtituting them into the message
directly, or switching on their values.

The message catalog files (MO files) just have flat strings with no
notion of substitutions or function calls. This is why my first
inclination was to generate elisp code from a Fluent file.

The easiest way to mush gettext and fluent together is to put some
syntax into the messages that is post-processed before being returned to
the caller, turning it into an interpreter. Something like this in a PO
file:

msgid "-sync-brand-name"
msgstr "Firefox Account"

msgid "sync-signedout-title"
msgstr "Connect with your {-sync-brand-name}"

A hypothetical igettext function could look for the curly braces,
recurse to find the value of the -sync-brand-name message, perform the
substitution (which allocates a new string), and then return the
result. Or the value of sync-signedout-title could be precomputed before
it was stored in the MO file. For this simple example, either would
work.

But consider a more complicated scenario:

msgid "tabs-close-tooltip"
msgstr "{$tabCount ->
    [one] Zamknij kartę
    [few] Zamknij {$tabCount} karty
   *[many] Zamknij { $tabCount } kart
}"

Again igettext can process this after retrieving it from the MO file,
but again it's just turning it into an interpreter for a slightly lispy
language. It could be partially unrolled into the MO file by using up
multiple strings in the MO file, but it would still need to be an
interpreter to substitute in the tabCount value. Good translations
frequently have more complexity.

I'd rather it were compiled to elisp that can be byte-compiled and
hopefully jit-compiled before too long.

Also, note that the original language wants to have the same
substitution capabilities as the translations. To my mind it would be
really weird to embed those in the source of the program that uses
igettext. Consider the following hypothetical example:

(message (igettext "{$tabCount ->
    [one] Zamknij kartę
    [few] Zamknij {$tabCount} karty
   *[many] Zamknij { $tabCount } kart
}" 42))

The PO file would look something like this:

msgid "{$tabCount ->
    [one] Zamknij kartę
    [few] Zamknij {$tabCount} karty
   *[many] Zamknij { $tabCount } kart
}"
msgstr "{$tabCount ->
    [one] Close { $tabCount } tab
   *[many] Close { $tabCount } tabs
}"

This may be really weird for the translator, because it seems to imply
that the degree and type of abstractions used in the translation is
supposed to match that of the original text, which is not necessary at
all. Thus I have kept the Fluent convention of using simple textual
identifiers in the source code, which is a departure from the way
gettext is normally used.

My thoughts have gotten more organized as I wrote this up, so I
apologize if I've skipped any important deductive steps or otherwise
left anything unclear.

Not quite. It's intended that various programs would either integrate
with an existing implementation, or implement the Fluent spec in their
own language where that's not convenient.

For example, a C program can link against the fluent-rs static library,
and thus avoid writing that code themselves. Of course depending on two
compilers (one for C and another for Rust, since fluent-rs is written in
Rust) is sometimes a deal-breaker.

I think we would ignore these existing implementations, except possibly
as a source of inspiration, and write our own.

> Is it feasible to write a small Fluent interpreter in C for this

Absolutely, but my personal preference is to write it in Elisp.

My second choice is actually to link against fluent-rs; Rust is a
great language and certainly better than C for implementing such
things. Of course that is it's own can of worms.

My third choice is to write an implementation in C. This we could
reasonably make a separate library we could share with anyone else
wanting to use Fluent in their C program. But then we would have to
write a lot of C.

We are still waiting for someone knowable of gettext to install the
gettext framework for translation of texts in C.  Adapting gettext
bindings to Lisp messages and UI would be more trivial to do.

Interesting.  Where can I read about the "basic design guides of Emacs
Lisp"?

I looked at "(elisp) Programming Tips" but did not find anything.  rgrep
on the emacs repository shows some counter-examples, i.e. stuff added in
the name of symmetry.

It is not clear, what exactly "the idea of adding more functions in the
name of symmetry" means.  Elisp has = /= < > <= >= predicates.  Does it
mean that <= /= > >= are against that idea because they can be trivially

rgrep gives me the following hits:

216 "(not (="

 12 "(not (<"
  3 "(not (<="
  1 "(not (>="
  0 "(not (/="

Each usage of not makes the code harder to reason about.

I personally prefer the following heuristic:

- use < and <= rather than > and >= (read the predicate left to right
  from smaller to bigger values)

- prefer when/unless/while/until and swap if branches to using /= or
  negation

This way there is almost no need for /= > >=, except they are still
needed for convenience when used in a different context, e.g. when
passed as an arg to a function.

rgrep on the emacs repository gives me the following counts:

732 "(> (length"
703 "(= (length"
151 "(< (length"
 71 "(>= (length"
 66 "(<= (length"
 46 "(/= (length"

Using length in a predicate smells fischy.  It is most likely a source
of unnecessarily burned cpu cycles.  It might be futile to train
programmers to keep that in mind but it is relatively easy to find and
fix.

There are (+ 732 703 151 71 66 46) => 1769 potential cases in emacs.
That's quite a lot of potential low hanging fruit for improvement.

Defining all those predicates will allow to syntactically fix those
places without touching anything else.  Once those predicates are in
place, we can be _sure_ that emacs is not uselessly counting length of
lists in predicates.  And those predicates could be further improved and
optimized in the future without affecting the call sites.

Now the questions is, how should such predicates look like.  Ideally,
they would look like = /= < > <= >= (accepting rest args) and numbers or
lists where for lists lengths would be computed but short-circuited.
But such generality might be overkill so I do not have an oppinion on
that.

Another issue already raised was: in C or elisp?  If compiler-macros
were an option, maybe that would give the most flexible and efficient
implementation which would be easy to maintain.  But I do not know much
about such deep elisp details yet.

length is different than map and dolist.

length is about a property of a list, namely about number of items.

map and dolist are about doing something with items of list.

Using length in a predicate is yet completely different and most likely
bad because to answer the predicate, traversing the whole list is wasted
time and energy.

The idea is that the intent is expressed in a way that can _guarantee_
that useless length computation is avoided.

In theory.  In reality, look at emacs code.  The new predicates will
allow not worrying about the trap and be sure that it is not there.  And
if somebody falls in the trap again, the new predicates will make it
easy to fix, simply by search and replace.

But how do you know if it has or has not performance impact unless you
investigate each case?

With the new predicates, you do not need to investigate each case
because it will be taken care automatically.

In fact, it kind of is, especially when used in a predicate.

Why?  That does not make sense.

Like Richard, I think that not all of the functions are needed,
because some can be trivially expressed by others.

I thought we always implemented only the minimum required set.  For
example, we have version<, but not version>=; we have
string-collate-lessp, but not string-collate-greaterp.  Why do we need
to stray from that principle in this case?  And if we must have all of
those functions, why cannot they share most of their code?

Everything that's not the same is different.

That's a quibble.  Length is about doing something
with the list elements: counting them.  It's no more
about a property of a list than is a function that
checks all the element types or, like `member',
finds an element that satisfies some condition.

(lambda (xs) (= (length xs) 25))  ; need to count elts

No, not completely.  The gotcha is much more general
than the cases that could be "fixed" using the
proposed predicates.

There are plenty of other possibilities for uselessly
invoking `length'.  Probably the most typical one is
neglecting to find the length only once and save it
in a local variable.

How much existing code (probably/hopefully mostly
outside the core code) does that, instead of this?

(let ((len  (length xs))) ... len ...len ... len ...)

A quick grep won't find places where code unwisely instead
does ... (length xs) ... (length xs) ... (length xs).

My guess is that those oblivious to the problem/gotcha
do that much more often than they do a single `length'
in a predicate that doesn't logically need to traverse
the whole list.

The point is that it's possible to misuse `length'
(and `dolist' and `member' and ...).  And no creation
of `length<' etc. predicates helps.  It fact, it can
hurt, as I explained previously.

See above - this is best done case by case.  As with
all attempts to improve performance.  Do it when it's
appropriate/needed.  If you don't know whether it's
needed then don't do it.  If it's really needed you'll
know or you'll find out.

Premature or otherwise misguided optimization essentially
works against Occam's razor.  Relevant/necessary
optimization is just the opposite: it applies Occam's
razor.

No, it kind of isn't.  Find the _actual_ places where
the core Emacs code is _really_ problematic.  See how
many there are, compared to that shotgun-blast `grep'.
Fix occurrences where the performance matters, i.e.,
those that are really problematic.  End of story.

`length<' & compagnie: YAGNI.

Is that a joke?

The predicates were proposed to help programers avoid writing such bad
code.  And if somebody writes such bad code, it is almost trivial to fix
it with search and replace:

   "(= (length" -> "(length="
   "(< (length" -> "(length<"
   "(> (length" -> "(length>"
   "(/= (length" -> "(length/="
   "(<= (length" -> "(length<="
   "(>= (length" -> "(length>="

Also the "symmetry" (or exhaustiveness?) here is to assist in easily
fixing bad code with minimum changes.

Nothing of course helps to those who are determined to unneccessarily
count _all_ the elements of lists.

Yes, I think <, = and > are the ones that are nice to have.  The /=, <=
and >= are trivial to express via the others, so I didn't go there.

I'm generally in favour of >, but these two are almost only used for
sorting, which makes the other forms superfluous.  (I know that there
are people who insist that < should be the only operator, and they write
code like (if (< 50 tom's-age) ...), and in my experience that leads to
people not being able to read the resulting code.)

People say (if (< (length ...))) and (if (> (length... ))) (and =) all
over the place -- it's not used as a sorting predicate, so having the
these three seemed like the minimal set.

And I don't quite follow you -- they do share most of their code?  I
think you could push a few more lines into the shared function, but I
think the resulting code would be pretty obscure.

be able to say (if (length= foo 0)) with the same confidence and

I certainly don't know what you're thinking, but you enjoy being
cryptic, so that's pretty usual.

Or did you mean implement these functions by using Fnthcdr?  Sure,
that'd work.

It is unlikely that people stop counting all elements of lists.

However, if somebody writes such code, it is almost trivial to fix it
with search and replace:

   "(= (length" -> "(length="
   "(< (length" -> "(length<"
   "(> (length" -> "(length>"
   "(/= (length" -> "(length/="
   "(<= (length" -> "(length<="
   "(>= (length" -> "(length>="

(plus extra closing paren)

The "symmetry" (or exhaustiveness?) here is to assist with easily fixing
bad code with minimum changes, i.e. one does not need to think how to
express it using different code.

Example:

   (<= (length ...) ...)
   ->
   (not (length> ...))

Visually different.  (I hope I got it right:-)

versus:

   (<= (length ...) ...)
   ->
   (length<= ...)

Visually same.

So once in a while, it will be possible to search and replace those bad
cases without any mental overhead, just with visual review.

In any case, thanks for taking initiative and improving this!

Of course, it will work.  There is absolutely no need to reimplement it,
badly.

   > Why do you need to reimplement nthcdr, badly?

   Because people say (if (= (length foo) 0)) all over the place, without
   caring whether foo is a list, a string, or whatever, and I want them to
   be able to say (if (length= foo 0)) with the same confidence and
   convenience.

If the goal is to avoid writing bad code, then one should definitly
not be introducing something like length= as a means to evade it,
since both those forms are to be avoided.

There are probably many ways to implement it.

I can even imagine not adding any of those predicates and make the
compiler more clever, maybe using some kind of compiler macro on the
= < > /= <= => predicates.
That way the existing code would not need to be changed at all.
But this is not Common Lisp so it is probably not an option here.

   However, if somebody writes such code, it is almost trivial to fix it
   with search and replace:

      "(= (length" -> "(length="

   (plus extra closing paren)

Users will assume that these length>= hacks will make their code
magically better, when they just hide a problematic form -- doing a
possibly complicated operation inside a predicate call.

In terms of nthcdr, length< would look like this, and would work for
bignum values of LENGTH.  And it's 15% slower for the benchmark I'm
using:

(let ((list (make-list 10000 nil)))
  (benchmark-run 100000000 (length< list 200)))

DEFUN ("length<", Flength_less, Slength_less, 2, 2, 0,
       doc: /* Return non-nil if SEQUENCE is shorter than LENGTH.
See `length' for allowed values of SEQUENCE and how elements are
counted.  */)
  (Lisp_Object sequence, Lisp_Object length)
{
  if (CONSP (sequence))
    return Fnull (Fnthcdr (Fsub1 (length), sequence));
  else
    return CALLN(Flss, Flength (sequence), length);
}

It will make their code better.  I do not see any magic there, it is
pretty simple and logical.

Do you have some other solution on mind?

Some of them can no doubt be replaced by multiple-value-bind and other
such things. This one from ido.el:1518, for example:

    (if (and (listp (car l))
             (> (length (car l)) 2)
             (let ((dir (car (car l)))
                   (time (car (cdr (car l))))
                   (files (cdr (cdr (car l)))))

could be (multiple-value-bind (dir time files) (car l) …).

But those kinds of improvements take a lot more thought about each
occurrence.

Incidentally, I find it hard to believe that someone typed all of that
out without at least using cadar and cddar.

It's very old code...  didn't `cadar' and friends get added kinda late?
(I.e., 90s?)  I vaguely seem to remember them living in cl.el for a
while until people were convinced to hoist them to Emacs proper.

A quick check does show that they were moved to subr.el from cl-lib.el
just three years ago. Nearly four now. Also that they were called
cl-cadar and so on. Weird.

   The goal is to avoid writing bad code and also to easily fix existing
   bad code.

If (> (length foo) 10) is bad or not depends entierly on its context.

   Why?

If foo is a list, then you should use null.  If foo is a string, you
should use string-empty-p.  If foo is some other, you should use that.

Oh, right.  But before the cl->cl-lib makeover, we used to sprinkle all
(FSVO) files with

(eval-when-compile (require 'cl-macs))

and `cadar' and friends were ... macros?  Hm.  Well, I know I've used
`cadar' before 2017 somehow.  :-)

That's because they suck.  They feel to me like programming in
assembler.  You're usually much better off using `nth` or `pcase` or
`cl-destructuring-bind`, ...

No, they were functions, but inlined at compile time (just as is the
case now).

Very good.  Now the other ~1700 cases.

I think you introduced two bugs:

1) missing &rest, it should be:

   (multiple-value-bind (dir time &rest files) (car l) …)

2) multiple-value-bind throws an error if it does not fit.  The original
   code does not seem to throw an error.

But all this excercise for single case took mental effort, got it wrong
and the change would need to be carefully undertaken.

The point of the predicates is to avoid such rewrites and improve the
code simply by search, replace and visual substitution without thinking
hard and introducing bugs.

Definitely. But a common enough pattern is to use list structure as if
it were a struct, with constructors and accessor methods that hide the
implementation details:

    (defun make-complex (x y) (cons 'complex (cons x y))
    (defun complex-x (c) (and (eq 'complex (car c)) (cadr c)))
    (defun complex-y (c) (and (eq 'complex (car c)) (cddr c)))

That is, the c*r methods are good and useful predefined accessors, but
you give them appropriate names so that you're not using them
directly. That way you don't make your users remember how to use these
generic accessors with your custom data type.

   It will make their code better.  I do not see any magic there, it
   is pretty simple and logical.

I don't see how.  The pretense here is optimization, the user has to
be active no matter what even to discover these functions.  The two
functions are advertised as equal as well, so there is no possible way
for the user to know which one to use when, and it might be suprising
that the behaviour (in run time) is different.


If the two forms are exactly equivalent, then the bytecompiler should
be able to do the work instead of the user.


And is it just me, but I'd expect that length>, etc takes two or more
sequences and returns a boolean if one of sequence is
larger/smaller/equal/...

I do not use anything.

The bad code _is already_ in Emacs.

For new code, suggestions are nice, but will likely not bear much
fruits.

Also (if (null foo) ...) is ugly, (if foo ...) is much nicer.

I agree with Stefan.  If you insist on defining
such predicates, please just do it in Lisp.

(defun length> (xs n)
  "Return non-nil if length of sequence XS is greater than N."
  (if (consp xs)
      (nthcdr n xs)
    (> (length xs) n)))

(defun length< (xs n)
  " Return non-nil if length of sequence XS is less than N."
  (if (consp xs)
      (null (nthcdr (1- n) xs))
    (< (length xs) n)))

(defun length= (xs n)
  " Return non-nil if length of sequence XS is N."
  (if (consp xs)
      (let ((ys  (nthcdr (1- n) xs)))
        (and ys  (null (cdr ys))))
    (= (length xs) n)))

or similar...
___

Of course, those can give values for some inputs
where the list is dotted, and raise errors for others.

But so can the C implementation you showed for `length<',
IIUC.  And testing for a `proper-list-p' anyway means
traversing the full list.

This is another reason I'm not crazy about Emacs adding
and promoting such predicates.  Better for users to try
to DTRT in any particular case.  Promoting these is likely
to encourage blind use.

At a minimum, the doc should say that if you want to be
sure a returned value makes sense then be sure the list
arg is a proper list.
___

An alternative (better, IMO), is to have such predicates
always return a nil or non-nil value.  The following
definitions do that.

For these definitions a dotted list acts just like the
same list without the dot, i.e., an atomic last cdr Z
is treated like (Z).  So the dotted list (a b . c)
behaves for these predicates just like (a b c).

And they apparently work fine for circular lists also.

(defun length> (xs n)
  "Return non-nil if length of sequence XS is greater than N."
  (if (atom xs)
      (> (length xs) n)
    (condition-case nil
        (nthcdr n xs)
      (error nil))))

(defun length< (xs n)
  "Return non-nil if length of sequence XS is less than N."
  (if (atom xs)
      (< (length xs) n)
    (condition-case nil
        (null (nthcdr (1- n) xs))
      (error t))))

(defun length= (xs n)
  "Return non-nil if length of sequence XS is N."
  (if (atom xs)
      (= (length xs) n)
    (condition-case nil
        (let ((ys  (condition-case nil
                       (nthcdr (1- n) xs)
                     (error nil))))
          (and ys  (null (cdr ys))))
      (error t))))

Not sure what do you mean.  The intention of the proposed predicates is

There are more things in life than lists ...  length on a char-table
or a string is constant.

What is trying to be optimized here is not (PREDICATE (length ...))
but rather the implicit list-length, i.e. (PREDICATE (list-length
...)).

   The bad code _is already_ in Emacs.

Then that code should be fixed, it will be needed to be fixed anyway
-- a new function won't fix it magically.

I was agreeing with both you and Alfred. His point seemed to be that
length> is a bad idea because there are better alternatives. There are
often better alternatives but, as I pointed out, using them takes a lot
more thought. I didn't expect my use of multiple-value-bind to be
perfect, since I spent only a minute looking at the code and hadn't
tested it. I didn't expect anyone to write back five minutes later
to point out not one but two problems with it though!

I think length> and family are a good idea (though I would have gone
with the longer-than-p suggestion instead), but that it's also a good
idea to use alternatives when possible.

   It is fascinating how many people with strong opinions do not understand
   the problem with

      (> (length x) 2)

You are assuming that X is always a list, there are far more types
than that in Emacs Lisp.  Replacing every instance of (PREDIATE
(length ...)) with (lengthPREDICATE ...) doesn't really do anything at
all for the cases where we are not working with a list -- which you
cannot possibly know just from a grep of the code.

   And if they fail at that, someone can once in a while fix that
   easily by search, replace and visual review without introducing
   bugs.

But nothing is fixed by such a change, thats the whole point, if you
are working with strings you are not fixing anything!  You are
introducing a gratious change that does absolutely nothing.

   Which two functions are advertised as equal?

Should have written forms, length> and (> (length ...), and the other
variants.

   What does "sequence is larger/smaller/equal" mean exactly?

(> 6 5 4 3 2 1) --> t
(length> '(1 2 3 4) '(1 2 3) '(1 2) '(1)) --> t

(elisp) Programming Tips

   • Use lists rather than vectors, except when there is a particular
     reason to use a vector.  Lisp has more facilities for manipulating
     lists than for vectors, and working with lists is usually more
     convenient.

     Vectors are advantageous for tables that are substantial in size
     and are accessed in random order (not searched front to back),
     provided there is no need to insert or delete elements (only lists
     allow that).

We are not trying to solve non-issue here.

Yes.  But that code will not fix itself magically on its own.  Somebody
will have to do it.  The new predicates address this need and will help
the person to do it easily and without introducing bugs.

I do not need to know.

I know that after the change, the good cases will stay good and the bad
cases will be improved.

They compute the same thing differently.

Like these two forms compute the same thing differently:

(progn 1)

vs

(progn (sleep 10) 1)

or even (I already mentioned that earlier):

(length> 5 '(1 2 3 4) '(1 2 3) 2.33 '(1 2) '(1) -42) --> t

But this is not so important. A simple two arg function would help to
fix most or all of the bad cases.

Ultimately, the person who implements this will decide.

So you are suggesting that one should change code just to change code?

So we agree that Emacs has more types than lists.

   We are not trying to solve non-issue here.

Did you check each case where length was used that it was actually on
a list?  If not, how can you possibly know that it is a non-issue?

   Yes.  But that code will not fix itself magically on its own.  Somebody
   will have to do it.  The new predicates address this need and will help
   the person to do it easily and without introducing bugs.

And broken code that does something stupid, will not get fixed by
length> or its equivalents.  If one wishes to actually fix code, one
cannot do so blindly..

The idea here is only that we should not _automatically and rigidly_
complete every symmetric set of possible functions.  (Because that way
lies more bloat.)

I describ this as a "design guide" because that is different from a
rule.

If we had a rigid rule against full symmetric sets of functions, these
comparison functions would break the rule.  To be rigid about it, we
would be "obligated" to delete some of them.

However, the idea of the design guide is to reject the rigid rule,
which some systems seem to follow, that every function _must_ be part
of a full symmetric set.

An implementation in Elisp could be ok for Emacs, but Emacs is just
one of hundreds of GNU packages, and one of thousands of packages in
the GNU system.

To fully adopt Fluent along with gettext as the GNU method of handling
this, we need to make it work in C programs.  The only simple, clean
and general way is to implement it in C.

Maintainers will never adopt this if their programs need to link
with Emacs or with Rust.

I don't follow how the beginning leads to the conclusion.

That is too terse for me -- I am totally list.

                                                Something like this in a PO
  > file:

  > msgid "-sync-brand-name"
  > msgstr "Firefox Account"

  > msgid "sync-signedout-title"
  > msgstr "Connect with your {-sync-brand-name}"

I see what it says, but can you explain how that relates to "syntax
that is post-processed before being returned to the caller"?  Terse
references such as "the caller" leave me lost because I can't tell
what they refer to.  The leap is too long for me to follow.

What does "the original language" mean here?

If it's like the C code posted here earlier then
it won't work for dotted or circular lists.
It'll do something, but not what one might hope.

I addressed this (in Lisp) in my previous mail.
If you insist on implementing this in C, at
least please consider doing something similar,
to handle these cases.

Certainly most programs cannot link to Emacs; Emacs isn't even designed
for that. Rust _is_ designed to be linked with C programs, and it is an
excellent language to write things in. It is only my opinion, but Rust
is a significant long-term threat to the ubiquity of GCC. Another
similar threat is the low quality of the C language itself. To counter
this, GCC should grow a Rust front-end. I hope that the work has already
begun.

But that is a topic for a different day.

I would not volunteer to write any large amount of C. I know C, and am
good enough with it, but suffering the aggravations of the language is
not my idea of a good time.

Again it's just my opinion, but Emacs could link against Rust code such
as fluent-rs if we wanted it to. The Rust compiler is free software, and
has become readily available in most Linux distributions. There are no
technical roadblocks either. I have no idea what it would take for
people to want it, but I'd volunteer to help if they did.

My apologies. It seems that I stated some of my conclusions and then
followed them up with supporting examples.

The caller is some part of Emacs, let's say. Emacs calls the hypthetical
igettext("sync-signedout-title"), and the translator wants Emacs to get
the string "Connect with your Firefox Account" (I've just copied this
example from projectfluent.org, which got it from the Firefox source
code). With this simple proposed syntax, igettext must inspect each
string that it retrieves from the message catalog to see if it contains
any substitutions. Those substitutions can be almost as recursive as a
real lisp program, and they can have conditional statements like lisp
programs.

Thus I would prefer to just compile the Fluent syntax into Lisp
functions rather than to write a new interpreter. One build step for
Emacs would be to read in the Fluent files for all available
translations, and output ordinary .el files. Those .el files would then
be loaded during the bootstrap process, just like all the existing lisp
source files.

It occurs to me that one way to refine this a little bit would be to
directly output a elisp bytecode to a .elc file after reading in a
Fluent file. This skips a step, and makes distributing packages
containing translations easier. Making `load' recognize Fluent files
seems like it would tie everything up nicely.

Whatever language the user interface was originally written in. In the
case of Emacs, this is English.

The English "translation" of Emacs will want to use the same Fluent
capabilities that any translation would have access to.

May I understand if that proposal is to implement it in C or in Lisp?
Does that mean when (length< list-1 10) is implemented in C it would
become faster than: (< (length list-1) 10) ?

Or is that proposal to make Lisp functions like:

(defun length< (list n)
  (when (< (length list) n)
  t))

That function could also test for second parameter if it is something
else but number to help in testing (length= list list) as well or
strings.

I will start using it.

Rust is able to generate C dynamic library, so we can link with it.

The dynamic library generated by Rust often statically link with its
Rust dependencies(unless that dependency is a C lib wrapper). So
it's not difficult for user to get it.

I can ask upstream whether they have interest in maintain a stable C
inteface, if they can help, we don't need to reinvent wheels.

You can take a look at librsvg[1] (from project GNOME). A SVG renderer
powered by Rust(and it's also used by Emacs currently)

They're already implemented in Emacs master, and they're in C. As I
understand it, one of the main advantages (beyond being simply faster,
possibly) is that they return early: if all you want to do is check if a
list has more than 2 elements, you don't have to calculate the whole
length, you can return t once you've found the third element.

Fluent offers a possible way of improving translation handling for the
whole GNU system.  That's what's really exciting.  It would make no
sese to do as much effort, or perhaps even more, to get support for
Emacs only and no other programs.

Rust is not an option for the GNU system.  It has to be C.

I will bring this up in gnu-prog-discuss when I dig up the
link about Fluent from the previous messages.

Is Fluent a trademark?  Is there a trademark license in Fluent?
If so, could you please send me the full text of that, as well as its URL?

I am interested in understanding what that means.  Could you describe
in 10-20 lines what it means?  What is the input, what is the output,
and what software does the conversion?

That is not something I can feasibly do -- it would take an hour if
not several hours for me to learn the basic points.  So I hope
you will describe what I need to know in a brief summary.

But I think it would be a nuisance to make this a separate library.
It should be packaged with the support for getopt, and written in C so
we (the GNU Project) can easily maintain it.

From what I hear, Rust has a fundamental practical flaw: it is not
intended to be stable.  The developers want to keep changing it.
That's fine, in principle, but until they decided to make it stable,
we should write important code in some other language.

In principle I agree.

In practice, I find it sad that you would tie the success of GNU to the
fashion for a single programming language. C has been successful so far,
and has lent that success to GNU, but it seems unusual to decide that
the GNU project could never embrace another language and allow it to
become coequal with C. But of course it's not my decision.

Good question; I'm not really sure. It's a Mozilla project, so I assume
it's like Firefox. I'll check.

It's just like compiling C into a library, but it's the Rust compiler
that creates the library. Other programs can then link with the library
as if it had been written in C.

Ah, a concrete objection. This isn't quite true. The language is indeed
evolving more quickly than C (which has at least four or five versions
now). Mozilla has committed to keeping the Rust compiler
backwards-compatible with all past Rust Editions, of which there are
currently two. Code written to the 2015 or 2018 editions of Rust will
remain compilable by all future versions of the Rust compiler. You can
also mix and match them; a program written in Rust 2018 can have
dependencies written in Rust 2015 and visa versa.

In practice it's not really different from choosing between c99, c11,
and the rest.

In general, I don't.  However, most GNU packages are written in C, or
C++, and that includes the gettext support that this ought to be
included in.  To use a different language there would risk complications,
and it is better to avoid them by writing that program in C.

The program must ne small enough that rewriting it is not a big hassle.

Just create a small example to help you understand how Rust interact
with C. link here: https://github.com/cireu/jieba-cbinding-example

jieba-rs is a Chinese segmentation crate(crate means library). CJK
languages usually don't use space to separate words so somebody create a
library to do it.

Please see jieba_rustlib/Cargo.toml, we have `crate-type = ["cdylib"]` in
lib section, so cargo(the builder of Rust code, like make) will ask (rustc)rust
compiler to generate C dynamic libraries.

I write a simple interface in jieba_rustlib/src/lib.rs. See the function
with `unsafe extern "C"` and `#[no_magle]` mark, it's marked for FFI to
C.

There're several ways to expose Rust API to C. Some simple types(int,
uint) will have corresponding mappings. For complex type like struct, we
can use #[repr(C)], make the struct layout compatible with C, so C can
access struct directly. Or just use pointer, let C treat Rust struct as
opaque object and use exported function to use it.

I use both in this example, for Jieba struct(introduced by jieba-rs
crate), I use pointer, for hand-craft compat layer of Rust dynamic array
and C arrays, I use C-compatiable struct to expose extra
information(length and capacity) of array to C.

And we use cbindgen(https://github.com/eqrion/cbindgen) to generate C
header, and result in jieba_rustlib/jieba_rustlib.h.

Finally we have dynamic library and header, we just include header in c
source(see main.c) and link with library to craft our application. I use Makefile to
automate these steps.

```
chino@asus-laptop:/archive/gitrepos/jieba-rs-c-binding-example$ LANG=en_US.utf8 make

I think Rust will keep evolving. But not aggressively.

The latest Rust stable version is 1.48. When a software/library
released it's 1.0 version, usually means it's production ready.

Cargo(package manager and build system for Rust) have lock. Users can
lock their crates to ensure a reproducible build.

And Rust also introduce "Edition" for breaking
changes(https://doc.rust-lang.org/edition-guide/editions/index.html).
It's stable if user stick to a specific edition. Any updates in same
edition should not break your code failed to compile/failed to run(if
so, it's probably a compiler bug).

The suggestion above is to build a shared library (.so, .dll, etc), but
written in Rust instead of C. That requires a Rust toochain to compile
the code.

Rust is a language that fits the same space as C does: a systems
language with minimal runtime support needed (so ok for embedded
targets). It has good interop with C, so Rust code and C code can call
each other directly without any complicated FFI or marshalling.

For the example SVG library, that allowed the authors to rewrite parts
of the C code in Rust for better type safety (to reduce the number of
security critical bugs) without changing the library ABI.

The language core is stable now, and current work is mostly on
stabilising libraries. Rust is a promising language, and while not yet
completely stable the pace of change is slowing as it matures. Many
projects are using Rust in production code.

Adding another toolchain to the dependencies for a project is a large
change. In addition, the Rust toolchains do not (yet) support many of
the targets that are supported by C toolchains.

It is also to note the freedom issues with Rust trademark as those are
similar to Firefox trademark issues.

Is this the set of C-code definitions you implemented?

https://repo.or.cz/emacs.git/blobdiff/714ca849ba658405ddde698cdc5836c4c9b289ca..0f790464d547dd57a857d88dab309b286067ac45:/src/fns.c

Let me say at the outset that I'm no expert in C code.

But it looks to me like this might have the problems
I spoke of wrt Lisp implementations that don't handle
dotted or circular lists correctly.  Is that the case?

For circular lists, it looks like you just raise an
error systematically.  To me, that's not as good as
it should be.  The Lisp definitions I provided work
fine for circular lists - their length is greater than
any numeric value, through ` most-positive-fixnum'.
(The function `nthcdr' is well-defined and performant
for a circular-list argument.)

For dotted lists, I cited the fact that simple Lisp
definitions of the `length(<|=|>)' predicates can
raise an error for some inputs and for other inputs
return the same length as if the last cdr were
wrapped in `list'.

IOW, the behavior is inconsistent: no consistent
notification (e.g. error) that the list is dotted;
silent answers as if the list were not dotted, in
~half the cases.

Does your C code have these problems also?

The Lisp definitions I posted don't have these
problems.  They handle circular and dotted lists
fine.  For dotted lists, the length returned is
always the same as what it would be for a proper
list equal to the dotted list but with the last
cdr wrapped in `list'.

I imagine that the same approach I used in Lisp
could be used in C, with no loss in performance
wrt the code you have.  But again, I'm no expert,
especially in C.

In case you missed the Lisp definitions I'm talking
about, they're at the end of this message:

The predicates are trying to fix cases where people use length.

(length '(1 2 . 3))

Yes.  And?

If we're defining predicates to check whether the
length of a list is <, =, or > some value, those
predicates should do something useful, or at least
something one might expect, for non-proper lists
as well, no?

If you check `length<' for a dotted list, whether
on purpose or not (e.g., knowing, not knowing or
not caring whether the list is proper), would you
really expect that a true/false value would be
returned and sometimes an error would be raised?

I think it's more useful for a reasonable value to
always be returned for that.  Or one could argue
that an error should always be raised for that.
But sometimes true/false and sometimes raise an
error?  Why would we choose a design like that?

What exactly means "something one might expect"?

I expect the predicates to work on proper list and it should count the
number of cons cells in the list.

I do not expect the predicates to count the last cdr differently
depending on its value.

The question iss not what the behavior should be
for proper lists.  The question is what it should
be for dotted lists (and circular lists).

What is your reasonable expectation for dotted lists?

I'd suggest these are two reasonable expectations
for a dotted-list length comparison against a number:

1. Always raise an error.
2. Never raise an error.

For #2, one reasonable expectation is, I think,
that the value returned always be true or false,
and exactly mirror the case for a proper list
whose last element is the last cdr of the dotted
list.

That has a good deal of consistency.  Non-nil
cdrs are simply counted (irrespective of their
non-nil values).  Nothing more happens.

(And the same can be said for a proper list:
the non-nil cdrs are counted - nothing more.)

"List" includes both proper and dotted lists.
Because a list can have a non-nil last cdr, it's
non-nil cdrs that I'd expect should be counted,
not cons cells.

But that's me.  To me, that behavior for dotted
lists would at least be of some _use_.  Always
raising an error for a dotted list is less useful.

But even if for some reason (what reason?) you
think #2 is _more_ useful, we don't even have #2.

The question really is, What behavior do you want
for a dotted list?

So far, the behavior is to sometimes (1) raise
an error and sometimes (2) return a true or false
value.  And there's little rhyme or reason for
when it does one or the other.

These use my Lisp definitions, which I guess do
what the current C code does for dotted lists:

(length> '(1 . 2) -1) ; true
(length> '(1 . 2) 0)  ; true
(length> '(1 . 2) 1)  ; true
(length> '(1 . 2) 2)  ; ---ERROR---
(length> '(1 . 2) 42) ; ---ERROR---

(length< '(1 . 2) -1) ; false
(length< '(1 . 2) 0)  ; false
(length< '(1 . 2) 1)  ; false
(length< '(1 . 2) 2)  ; false
(length< '(1 . 2) 24) ; ---ERROR---

(length= '(1 . 2) -1) ; false
(length= '(1 . 2) 0)  ; false
(length= '(1 . 2) 1)  ; false
(length= '(1 . 2) 2)  ; ---ERROR---
(length= '(1 . 2) 42) ; ---ERROR---

Is that really what you expect/want?  Not I.

I prefer that those ERROR cases return false
for >, and true for = and <.  Which is what
I implemented.

I do not have an expectation for dotted lists except it should not
traverse the whole list in order to find out, if it is dotted or not.
That would defeat the whole idea.  It should do the minimum work
necessary to determine the predicate value and not bother with
determining if the list is dotted or circular.

Nothing in what I've written just traverses the
whole list.

The point of this thread is to have predicates
that check whether the length of a list (or
sequence) is < = or > some number WITHOUT always
having to traverse it entirely to get the answer.

[Of course, if the answer to (length= foo 42)
is YES then `foo' will be visited to its end,
in some way (e.g. `nthcdr') or other.]

All I've suggested is that instead of throwing
an error we return the obvious answer for each
case.  That's no more work than actually throwing
the error, AFAIK.

How about introducing a new variable with the tentative name
`this-mode-wants-toolbars' that defaults to nil?  If it is nil, there
are no toolbars.  This variable can then be set to t when someone has
made a toolbar that they know will be useful.

That way, there is less need for users to disable the toolbar globally
(unless you really want to), and they can benefit from this feature
where it is actually in a useful state.

One obvious drawback of this proposal is that it's slightly jarring when
the toolbar appears and disappears when switching between windows.
Perhaps we could show it if it is enabled in any buffer in a window on
the current frame?

I tend to agree.  The above proposal would leave this to the mode
author to decide.

(Well, in reality, the overwhelming majority run with no toolbars anyway.
So if you want your controls seen you should probably still put them in
the mode line.)

That makes little sense to me.  Other applications that show tool bars
don't make them appear and disappear, only change as appropriate for
the context.

Exactly.

So you basically want NOT to make it disappear?  Then why make it
disappear?

Which applications are you thinking of here, that would be comparable to
Emacs (i.e. are part music-player, part text editor, part hex editor, part
IRC client, ...)?

> Exactly.

I think the solution is to have toolbars inside the window's text,
rather than attached to the frame.

For mpc.el I played with the idea of building up a "toolbar" that gets
inserted into the buffer, but I didn't the time needed to get something
good enough.

I don't see how this is relevant.  The tool bar is part of the GUI,
which functions are shown there is immaterial.

Is this practical?  Windows can be very narrow, and change dimensions
much more frequently in Emacs than frames.  Tool bars don't live well
with frequent changes in dimensions.

If someone wants to turn tool bar off, let them do that.  We don't
need to turn the Emacs appearance upside down just because of some
fashion: we already support that fashion.

(This is not what you're discussing now, I
guess, but it can affect whether a user's
choice of whether to use tool bars.)

I'll just mention again that users can have a
popup tool bar.  IOW, show it only on demand,
for a single action.

Also, ability to show the tool-bar only for
the current frame.

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

This or a similar feature could be added to
vanilla Emacs.

Note that with GTK the outer frame shrinks/expands when the toolbar is
removed/added.  Not talking about the GTK3 warnings when the toolbar
doesn't fit ...

It's relevant in the fact that some of those applications may come with
a toolbar while others don't, so a single application that provides
access too all those facilities (like Emacs) may want to sometimes show
a toolbar and sometimes not.

I'm suggesting to *add* "in-buffer" toolbars (hopefully as a pure-ELisp
feature).

In the spirit of this discussion on the merits and possibility of
planning (or not), there is an interesting quote below.
I found it useful for thinking about the special characteristics of
Emacs, and perhaps others on this list will find it interesting to
consider.




attributed (in the Free as in Freedom book)to RMS from a 1979 AI Lab memo


 EMACS could not have been reached by a process of careful design, because such
 processes arrive only at goals which are visible at the outset, and whose
 desirability is established on the bottom line at the outset. Neither I nor
 anyone else visualized an extensible editor until I had made one, nor
 appreciated its value until he had experienced it. EMACS exists because I felt
 free to make individually useful small improvements on a path whose end was not
 in sight.






Although I couldn't locate the original source of exact quote, there is a longer piece
from the 1979 memo from RMS on the same subject.




Implications for the Process of System Design 

It is generally accepted that when a program is to be written, specifications 
should be designed in advance. If this is not done, the result will be inferior. 
Some people know better than this, but none dare to speak up. 

The writing of EMACS was as far from along these lines as can be imagined. It 
is best thought of as a continuous deformation of TECO into something which, 
for users, has no resemblance to TECO. 

And indeed, there are ways in which EMACS shows the results of not having 
been completely thought out in advance, if only in being based on TECO rather 
than Lisp. (Nevertheless, EMACS has shown itself to be reliable and suitable for 
widespread use). If EMACS hadTbeen specified in advance, it would resemble 
the post-EMACS editors described above. However, the post-EMACS editors 
were specified in advance by EMACS itself, and could not have been written if 
not preceded by EMACS (this is not to say that they have copied slavishly; they 
have continued the process of gradual development). And EMACS could never 
have' been arrived at except in the way it actually was. The chain of necessary 
steps leading to EMACS, starting with the display processor, was simply too long 
for anyone to have imagined the final result before the first step had been taken. 
If we had insisted on moving only toward destinations visible at the beginning, 
we would never have got here from there! 

This is true of all the details of the individual commands as well as of the 
structure of the system. Each command in EMACS behaves as it does as a 
result of experimentation by many different users customizing their editors in 



£ MACS June 22, 1979 



21 



MIT Al Lab 



different ways, in the years when the display processor existed but EMACS had 
not yet been begun. This experimentation was possible only because a 
programmable display editor existed. It would not have been possible to design 
the EMACS standard command set without it. 

Nor can one maintain the position that it was right to create EMACS this way 
because it was research, but ordinary system development is a different matter. 
This is because the difference between the two is also a matter of hindsight. 
EMACS was not the result of an intentional "editor research project" (nor would 
such a project have arrived at EMACS, because research projects aim only at 
goals which are visible at the start). The display processor and command 
dispatcher were seen only as an improvement to TECO; no one could have 
known, when any step was taken, how much farther the path would lead. One 
cannot even identify a "first" step, because the development, until the writing of 
EMACS per se, blends smoothly back into the development' of TECO. 

But why isn't such program of exploration doomed to be sidetracked by a blind 
alley, which nobody will realize due to the lack of a planned goal? 'it is the 
extensibility, and a flexibility of mind, which solves this problem: many alleys 
will be tried at once, and blind alleys can be backed out of with minimal real 
loss.

Which significant applications don't have a tool bar at all,
i.e. don't even have an option to display a tool bar?

By what logic?

The tool bar in Emacs is very like the menu bar: it provides quick and
easy access to some frequently-used functions.  Which application
doesn't have any such function to justify the lack of a tool bar?

So your suggestion is to have _both_ the frame-global tool bar and
another tool bar displayed in some windows?  That'd be fine with me
(we already have some modes display a header-line, which is a kind-of
tool bar, and we now have the tab-line as well, so we have similar
functionality already).

Yeah, I think that's the way forward.  Having the toolbar in the window
will allow much greater flexibility, and allow users to switch the
toolbar on in modes where it makes sense.

By "inside the window's text" do you mean anywhere
within it, so for example a user could move it
around within that space?  Or do you mean something
more like what Eli suggested - perhaps handled like
a header-line is handled?

In what you imagine, would more than one such tool
bar be possible within the window's text area?

I guess my overall request here is whether you can
perhaps flesh out more of what you (plural) have
in mind.

I don't know what other people mean, but what I'm thinking of is
reflected in the chunk of code below I started writing some years ago.
You can `insert` the result into the buffer to put a toolbar wherever
you want (don't expect miracles: it has loads of shortcomings).

You should be able to do something like that with header-line.

I was thinking about this myself and wondering if you could do it with a
multi-layer hydra where you have a top-level hydra that you add/remove
lower-level hydras specific to the major/minor modes you're in.

Just a thought at the moment...
