[AUCTeX] Output parsing problems with LaTeX2e <2017-04-15>

[Uwe Siart]

When I type "C-c C-a" even on a very simple document like

\documentclass{article}
\begin{document}
Test
\end{document}

I get

,----
| LaTeX: problems after {1} page
| Type ‘C-c C-l’ to display results of compilation.
| LaTeX: problems after {1} page
| Type ‘C-c C-l’ to display results of compilation.

| LaTeX: problems after {1} page
| Type ‘C-c C-l’ to display results of compilation.
| Stopping after running "LaTeX" 4 times in a row.
| LaTeX: problems after {1} page
`----

This happens with AUCTeX 11.90.1 and the recent LaTeX format of
<2017-04-15> (TL17 pretest).

Don't know if this is a problem with AUCTeX or with the latest LaTeX
format.

I don't have problems with TeX Live 2016, so I'd bet on changes in TeX
Live 2017. It would be great if you could provide an example of
output buffer.

I can confirm that everything is fine with TL16 final. It only happens
with TL17 pretest. Here's the output buffer:

Thank you so much, I think I can reproduce the error. The problem
should related to the change of date format, now LaTeX2e uses ISO date
yyyy-mm-dd, in addition to yyyy/mm/dd (see the changes on 2017/04/15:
https://www.latex-project.org/news/latex2e-news/). You should be able
to fix this locally by replacing the line

\\(Version\\|ver\\.\\|<[0-9/]*\\(?:u[^>]*\\)?>\\)" nil t)

with

\\(Version\\|ver\\.\\|<[0-9/-]*\\(?:u[^>]*\\)?>\\)" nil t)

in `TeX-LaTeX-sentinel', file tex-buf.el. Can you please confirm this
solves the problem for you?

Thanks,
Mosè

Hello Mosè,

Yes, your fix works perfect. The problem vanishes with this.

Thanks!

Very good. I installed the fix into the repository. Thanks again for
reporting the issue!

Great! Would this fix justify another ELPA release (shortly after the
last one)? Propably, the new LaTeX format will be out in the wild very
soon. TL17 is sheduled for public release beginning of June, but don't
know when MiKTeX users will get it.

GNU AUCTeX 11.90.2 is on its way!

Hi all,

besides this, are you aware of any AUCTeX style which should be updated
for TL2017 release? Currently, I see only fontspec.el which should be
touched. And a fontification bug in comment.el where only the first
line in comment environment is fontified in `font-lock-comment-face'.

Best, Arash

Not that I know of but I don't follow the TeXLive development closely.

Feel free to do that. I have no clue if and what changed ther. ;-)

I've just fixed that. :-)

Hi Tassilo,

yes, same here.

Will do. Most notably, I like the new syntax in macros like \fontspec
et al. where the optional argument comes after the mandatory font name.

Thanks. While you're on top of font-latex.el game again, can you also
have a look at my proposal here?

http://lists.gnu.org/archive/html/auctex-devel/2017-04/msg00011.html

On my wish list is also correct fontification for optional and/or
mandatory arguments of math environments, e.g.:

\documentclass{article}
\usepackage{amsmath}
\usepackage[overload]{empheq}
\begin{document}

\begin{align}
a_1 &= b_1 + c_1
\end{align}

\begin{empheq}{align}
a_1 &= b_1 + c_1
\end{empheq}

\begin{empheq}[left=\empheqlbrace]{align}
\label{eq:2}
a_1 &= b_1 + c_1
\end{empheq}
\end{document}

I think the functions `font-latex-match-math-envII' and
`font-latex-extend-region-backwards-math-envII' should be changed for
this. Right?

Best, Arash

Yes, I have no objections. :-)

Hm, I still have TeXLive 2015, and there I don't get that error. I'll
try updating to the current version 2016 (not 2017 pretest) and report
back.

Like Mosè, I can't reproduce the issue with TeXLive 2016. How would I
install the 2017 pre-release? (My google foo did not suffice...)
