LaTeX, long line, and synctex.
Hi here, When working with AUCTeX, if I have long-lines in LaTeX file, then the SyncTeX positioning will not so accurate. How to tackle this problem? Regards, Zhao -- Assoc.

Here is what I tried:
• emacs -Q
• Activated AUCTeX with 0 configuration
• Eval'ed the code above in scratch
• Opened the file ltnews36.tex
• M-x outline-minor-mode RET
• C-c @ C-t
and it looks like this:
You should really start sending recipes starting with 'emacs -Q' in

Soft wrap (again?)
Hi,
I know that the matter has been discussed in the past (e.g.,
https://lists.gnu.org/archive/html/auctex/2012-01/msg00025.html),
however looking at those past discussions I could not find a solution to
my specific problem, so please take my apology in advance for re-opening
the topic.
I am not interested in opinions on what one should use or the relative
merits of hard wrap over soft wrap or viceversa. Independently of this
(and even of my own preferences) I often need to cooperate with other
people who use tools based on the soft wrap approach (e.g. TeXStudio or
the online Overleaf editor) and follow their choices. Basically this
means that I often need to use soft wrap too.
In Emacs, using soft wrap means disabling auto-fill, rewiring your brain
so that you do not press "ESC q" mechanically, and enabling the
visual-line-mode. Even with this you miss all the nice indentation that
auctex provides, though. You can get a bit closer to it by enabling the
adaptive-wrap-prefix-mode. This is more or less what I found in the
previous exchanges.
However, I still miss one thing: the adaptive-wrap does not seem to
understand braces. Hence, when some "macro argument" gets wrapped, it
gets no indentation. For instance, I get
\section{This is a rather long section name that
gets wrapped}
and not
\section{This is a rather long section name that
gets wrapped}
The same goes with \emph, \foreignlanguage, \textbf, etc. Particularly
when things get nested it becomes a burden to check where the arguments
end and whether the braces are matched.
So my question is: are auctex and adaptive-wrap-prefix-mode two
completely independent packages, or is it possible for auctex to use its
"understanding" of LaTeX to provide hints to adaptive-wrap-prefix-mode
about the amount of spaces to use in the prefix for each soft wrapped line?
Thanks and best regards,
Sergio

Why do need > the fontification, jinx? Thanks for looking into this. Well, I've long yearned for a better fontification for them (you may recall: https://tex.stackexchange.com/q/425883). I am a regular user of citation lists, and frequently long ones at that. However, yes, now I'm using Jinx, and fontification became "functional" besides the eye candy. And indeed that's why I'm looking into this. Truth be told though that Jinx excludes `font-lock-variable-name-face' meaning the optional arguments of citation commands are not spell checked (https://github.com/minad/jinx/issues/25), so I'd need special treatment for these macros anyway. Thus, I really proposed this because it seemed simple enough and a fontification improvement. For the purposes of Jinx I cooked a function akin to `font-latex-match-command-with-arguments' which handles unlimited number of arguments and also instructs Jinx to spell check the optional arguments (under my setup). It is not too complicated either. Btw, I did send you that message in that Jinx thread in emacs-devel about the use of faces to handle spell checking exclusion (https://lists.gnu.org/archive/html/emacs-devel/2023-04/msg00512.html, though perhaps that thread was not the best place for me to chime in). And I'm still hoping someone will get interested in this. It is a really powerful and appealing approach for the problem. Not almighty, not without its own set of issues, but very promising. And, as I said there, there's no reason to assume it couldn't be used by the built-in spell checking packages. I'm still playing with that stuff, and I'd be happy to discuss and share if there's interest. Best, Gustavo.

Thanks for looking at this and your ideas about this issue. To be
honest, I'm not convinced that we should go through this only in order
to get cite lists working. The benefits for some macros provided by one
single package, namely biblatex, seem too low to me. We have a
non-perfect solution now, but I guess we can live with it. Why do need
the fontification, jinx?
What do others think?

In-buffer completion for package names and options
Hi all,
I think I have a working setup for in-buffer completion of arguments of
\usepackage and/or \RequirePackage. It needed some preparation (commit
28aa6b99e4) but it seems to work. I could apply the same idea to
\documentclass.
Patch is attached. Any comments welcome.
