Dmitry, could you please explain the reason(s) for the change below?

Vertical positions in a window can never be large enough to justify
using ptrdiff_t (on platforms where that is wider than a 32-bit
'int').  These are pixel positions on the Emacs display, so they
cannot be too large.  The type of 'first_vpos' looks especially
strange, since it is explicitly set to 1 at most.  I'm not aware of a
platform where an 'int' is not wide enough for a value 1 ;-)

Using inappropriate data types makes the code harder to read and
understand, because it hints that something non-obvious is going on
somewhere.

	 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
	 to ptrdiff_t.

Hi,

I'm a gnus newbie and using it for about two weeks in just one of my IMAP
mail accounts. I like it so far, but wonder at its marking system...

To the question: Does it make sense to not use gnus-ancient-mark "O"
completely? I want to see old marks that I laboriously set in previous
sessions, such as the gnus-del-mark "r" mark. It seems to be replaced by
"O" all the time.

If so how would I achieve this?

"r" just marks stuff as read, and this isn't saved beyond that.  Any way
of marking stuff as read ends up in the same data set, so it's all
displayed as "O".

I see, so the difference between "r" and "R" is just for the current
"summary mode" session.

Curious, when does adaptive scoring kick in then? It does differentiate
between "r" and "R" doesn't it?

Adaptive scoring kicks in as you're leaving the summary buffer, I think.

Unless objected to timely, I intend to push this change tomorrow.  It
should not affect current operation but brings Emacs' behavior for
synthesized Lisp events containing an "up-" modifier in line with the
current behavior of "down-" events.  Such events are not produced by
Emacs itself; no change in behavior for existing code is expected.

I have code that might eventually make it into ELPA that benefits from
these changes.

Hi!

About a year ago, the long time maintainer of the official Emacs user
interface on OS X (the "nextstep" or "NS" user interface), retired from
Emacs. This is very unfortunately, as he did a very, very good job for
during the years he was active.

When I found out about this, about six months ago, I stepped up as I had
some knowledge after having worked along side of him on some NS-related
features.

Unfortunately, my personal situation has since changed so I no longer can
handle the NS user interface by myself.

In other words, I'm looking for someone or a group of people who are
interested in enhancing Emacs on OS X, or at least making sure that it
doesn't stop working.

To make it easier to start working on the NS port, I've updated the README
and add a WISHLIST of features that I would like to see implemented.

I will still be around, but I find that time no longer permits me doing
much core development work.

Sincerely,
    Anders Lindgren

Actually, forget it. It's too complicated to jump through all the hoops here.

I would just be glad if someone applied the patch from bug 26068. It's a
fix, not an optimization, and there is example of a form, evaluation of
which it fixes.

Applied, thanks.  AFAICT it didn't break any tests and didn't exacerbate

Thank you. If you are familiar with the code involved, can you please also
look at bug 26073? It's related, but more difficult to fix. I added a patch to
the bug report, but I don't think the patch is ready for application. Maybe

I'm new to contributing, so I was wondering if this is a viable
project to get started on.

I've noticed that development on the Emacs Calc has stalled
recently. /lisp/calc shows no commits since January 1 2018, which was
a copyright year update. I would like to contribute documentation to
many of the undocumented functions, and work on the symbolic
integration algorithm which, despite its complexity, still has great
difficulty with integration by parts and by substitution.

What are some recommended starting points for first-time contributors?

Thanks,

[Ag Ibragimov]

Spacemacs (community-driven Emacs distribution/config) has a feature called Layers, Doom-Emacs (another community-driven Emacs config) has a similar feature (I think they are called Modules).

A Layer is a bundle of [related] Emacs packages that work together and very often tightly integrate (with one another) to provide a comprehensive set of features to achieve specific goals. For example, there are many language-specific Spacemacs layers: Python, Lua, Haskell, etc.
For example, the Python layer includes basic Python-related packages and sets defaults for Flycheck, Company, etc.
There also layers for tools like Docker or layers for version-control, et al.

So my question is: Has anyone ever thought about designing a sort of standardized module system? It would be great if we could have a unified model for creating such bundles.
Wouldn't be nice if for example, instead of discovering, installing and configuring a bunch of related packages, an Emacs user would say: "install LaTeX module" and then "customize "LaTeX module", etc.

Emacs ecosystem is growing. There are hundreds (maybe more) packages; standardizing a system that would allow the "plug-n-play" experience would be very nice. Otherwise, everyone would continue solving same problems in their own, unique ways, increasing entropy towards the "Lisp curse."

Subject: Load order for elisp files

I am trying to better understand the bootstrap process for Emacs and I
have run into a chicken and egg problem. When looking for where the
basic functions are defined, I can see that defmacro and defun are defined in
byte-run.el. However the code needed to evaluate a macro is in
backquote.el. But backquote.el uses defun, which is defined in
byte-run.el. Which of these files is loaded first, and how does Emacs
work around this apparent causality dilemma?

Hmm... no, the code in `backquote.el` is only used to macro expand uses
of backquotes (which are commonly used in macro definitions but not in
all of them) and `byte-run.el` is indeed careful not to use backquotes,
specifically because that would break the bootstrap.

IIRC there are cases where we rely on even more subtle details, more
specifically, I seem to remember that we have functions whose body uses
macros that aren't yet defined when we define the function, and this
still works OK because this is done at a stage where macro expansion is
still lazy, so the macros in the body of the function are only expanded
when the function gets called (or when it gets byte-compiled) both of
which "happen" to take place later, when the corresponding macros have
been defined.

byte-run.el does use backquotes

https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/emacs-lisp/byte-run.el#n122

However I had not thought about the impacts of lazy evaluation. I guess
this would require that you load the code twice: First with the
interpreter, then with the byte compiler, since you can't compile a macro
that has not been defined.

Right [except evaluation is not lazy, only macro-expansion is].

Indeed: we first load the interpreted code when dumping the
`src/bootstrap-emacs` executable, which is then used to compile the
preloaded files (and the compiler), after which we load them again (but
in their compiled form) to dump the final `src/emacs` executable.

Note that lazy macro-expansion is only used for some of the preloaded
files (more specifically for those loaded before `macroexp.el` in
`lisp/loadup.el`, where you can also see some hackish workaround we have
to use at that time).

I was wondering if you could make the following improvement to
GNU Emacs: Make it so that fonts with a nil for background-colour
have the fontification of the inner symbols shines through
to appear over higher layers, like so:

*abc* is fontified as a blue foreground with nil background

"*abc*" is fontified in light blue background with a black foreground
but should appear with a light blue background and a blue foreground.

Here is the Elisp code that I want the behaviour of which changed:

(set-face-foreground 'dmp-face--fg:blue "#000")
(set-face-background 'dmp-face--fg:blue nil)

("\\*.*\\*" 0 'dmp-face--fg:blue t)

Not only that. You can do things like raising Emacs to the top and other
system actions that would otherwise require (Objective-)?C functions in the
Emacs executable.

I know this may come late and be redundant, but just my .01 cents of
experience:
I have my own tweaked Debian infra to build emacs29 for Ubuntu and I have
native-compile enabled. All .eln files generated during build from the
emacs (git) source are stored in /usr/lib/emacs-xyz and are never
recompiled when I run emacs.

What actually gets natively compiled to $HOME/.emacs.d/eln-cache is any
package that I download from (m)elpa-xyz as a result of my
HOME/.emacs.d/init.el

I may be doing something wrong, but AFAIK it seems to work and I have the
same functionality on my Ubuntu natively-compiled Emacs and on the macOS
(both running +/- the same snapshot of the emacs master git branch), where
I have no native compilation.

I hope I somehow contributed something ;-)

Fine, I don't know either whether you should _recommend_.

But, at least mentioning that this can be done to have an initial configuration
to start with... There is no one fits all and some tweaks may be needed
in some projects, but an initial config can speed up the process and it is
'as bad as' putting the dir-locals in your git repo and someone opening it
with -say- vscode or vi ;-)

Two things to bring another perspective:

1.- the probability is high, but what do we do with the (1-p)... shy
them away? ;-)
2.- with the current landscape, even professional developers can't
sometimes do what they need.
There is this balance between productivity and security, which I do

hi.  i would like to be able to write Emacs scripts ("#!...") that allow
a user to enter almost any option to the script itself, *without* having
to use double dashes ("--") to avoid colliding with Emacs option
processing.

looking at "--script" and "-x", this doesn't seem possible.

as a test case, given a simple script foo.sh (*), using "-x", and
invoking it with an option "--eval" gives this error:

----
% ./foo.sh --eval
emacs: Option '--eval' requires an argument
----

(that bare "--eval" *should* be an error if it were meant for Emacs
itself; however, it is meant for the Emacs script, which may have other
ideas of the syntax/semantics of "--eval".)

the below patch to src/emacs.c (**) treats a "-x" (and its "partner"
"-scripteval") like a "--" on the command line, and *seems* to allow
arbitrary options on the command line.  for example, with this patch
installed:

----
% ./foo.sh --eval
command-line-args-left (--eval)
----


i wonder if this might be of use for Emacs?  if there are worries about
backwards compatibility with "-x", well ... "-y" anybody?  :)

(i was thinking of writing a test to go with the patch, but the ERT
framework is maybe a bit awkward for tests of essentially
shell-command-line functionality.  i may have missed it, but i didn't
see anything in ./test/Makefile.in that seemed to be aimed at testing
command-line invocation of Emacs.)

cheers, Greg

You could probably take some inspiration from the "Synchronous 
processes" section of the file test/lisp/eshell/esh-proc-tests.el. 
Essentially, you can just start a new Emacs instance in your ERT test 
and do whatever you like.
