Subject: 27.1; After Package Update Cannot Execute LaTeX Commands
Date: Thu, 07 Jan 2021 13:59:12 +0100

A few days ago I upgraded all packages using the command U. Also auc-tex
has been updated to

    Status: Installed in ‘auctex-13.0.1/’. Delete
    Version: 13.0.1


Today I want to compile a LaTeX file using XeLaTeX
but I get the folowing error:

Debugger entered--Lisp error: (error "Nonexpansion file")
  signal(error ("Nonexpansion file"))
  error("Nonexpansion %s" file)
  TeX-command-expand("xelatex -interaction=nonstopmode %s")
  TeX-command("XeLaTeX" TeX-master-file nil)
  TeX-command-master()
  TeX-command-menu("XeLaTeX")
  menu-function-53()
  funcall-interactively(menu-function-53)
  call-interactively(menu-function-53 nil nil)
  command-execute(menu-function-53)


Thanks for your help!
Nikolaus Thiel

Similiar issues were reported here[1] and here[2].  Can you please
delete AUCTeX via package manager, i.e., really delete and not moving
from `installed' into `dependency', restart Emacs, reinstall AUCTeX and
see if it helps?

Best, Arash

Sure welcome.  For future reference, please keep 45713 <at> debbugs.gnu.org

I can't reproduce this.  A small .tex file like this:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{fontspec}
\begin{document}
foo
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-engine: xetex
%%% End:
--8<---------------cut here---------------end--------------->8---

compiles with no problems for me, either by hitting `C-c C-c RET' or
from the menu Command->LaTeX.  Eval'ing

    (TeX-command-expand "xelatex -interaction=nonstopmode %s")

returns for me

    "xelatex -interaction=nonstopmode xelatex-test"

> What else could I try?

Standard debugging procedure I think: Start Emacs with -Q, eval
(package-initialize) in scratch buffer and then load your .tex file.  At
the end, a recipe to reproduce this issue is needed.

I've reassigned this report to AUCTeX.  Please open a new bug report for
the Gnus issue.

I'm not familiar with macOS, so I can't tell what's going on.  I can
only suspect that you've installed Emacs via MacPorts, and maybe you
have installed AUCTeX through MacPorts as well.

It seems that AUCTeX isn't loaded and you end up with Emacs tex-mode.

Be careful here; xelatex is running in interactive mode and expects an
input.  In your shell, try \relax RET \bye RET.

See above, I think your installation is broken.

Nope, I'm not on macOS.  Sorry, but I'm out of ideas here.  I can only
suggest that you delete all your AUCTeX installations (ELPA, MacPorts
etc.), load a .tex file and do `M-x list-load-path-shadows RET' and see
if you don't have dupe installations, restart Emacs, and install AUCTeX
via ELPA.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

No further comments, and I can't reproduce this on macOS, so I'm closing
this report.
