Subject: 13.0.14; Non-file-visiting TeX buffers
Date: Fri, 27 Aug 2021 09:20:54 -0300

Hi All,

Since the latest release (v13.0.14), I'm having problems opening a new 
`.tex' buffer (still non-file-visiting) when 
`TeX-view-evince-keep-focus' is `t'. As far as I can tell/recall, I did 
not face this until upgrading today (and this is a procedure I do 
commonly, but I did not rigorously test this to pin down the change).

An ECM to reproduce the issue is: start `emacs -Q'.

Do an initial setup:
#+begin_src emacs-lisp
(add-to-list 'load-path "~/.emacs.d/elpa/auctex-13.0.14")
(load "auctex.el" nil t t)
(setq TeX-parse-self t)
(setq TeX-auto-save t)
(setq TeX-view-evince-keep-focus t)
#+end_src

Now, find a `.tex' file which does not yet exist, say "~/test/test.tex" 
with `C-x C-f test/test.tex RET'.

We then get the error "File mode specification error: (file-missing 
Setting current directory No such file or directory 
/home/gustavo/test/)".

The file itself gets opened in fundamental mode.

With `M-x toggle-debug-on-error' and repeating the procedure, we get the 
following backtrace (its final part):

#+begin_example
Debugger entered--Lisp error: (file-missing "Setting current directory" 
"No such file or directory" "/home/gustavo/test/")

The problem is that not just the tex file doesn't exist but the
containing directory ~/test/ doesn't exist either.  But that seems to be
already set as `default-directory' so the shell commands testing for the
availability of the evince-based viewers should run in a non-existend
CWD.

Well, those tests will work the same no matter which
`default-directory', so we could bind `default-directory' to "~" for
those calls, I think.

I'll come to that when I find some spare time.

Bye,
Tassilo

Well, I always create "throw away" test files under a "throw away" dir, 
not to have to deal with stray `TeX-auto-local' directories mixed with 
my actual files.  ;-)

I'm not up-to-date with the recent changes related to the issue.  But I 
thank you for looking into it when you can.

That's a sensible habit.  I guess you haven't seen that error previously
because you always opened another tex file in some existing directory
first.  The error only occurred when tex.el was initially loaded while
default-directory was set to some non-existent directory.

No, the problem is definitely there since 2016, no recent change
involved.

Should be fixed on master.  Please give it a try.

Well, I was much surprised by this.  For I really do this frequently, 
and do it purposefully.  And have been doing it for some time.  Creating 
a new directory in the process is what ensures I'm getting a clean 
slate, so I'm sure to do it.  And the first time I met the issue was the 
day I reported it.  Since I had just upgraded AUCTeX, I assumed it must 
have been it, wrongly, as it turns out.  But I did some checking now.  I 
reverted to v13.0.13, and the problem was there.  Then to v13.0.12, and 
the problem was there.  I did upgrade my OS just this week (Mint 20.1 to 
20.2 Cinnamon), so there might have been some change on `evince's side 
making it less lenient.  Truth is: I don't know what changed, even 
though I'm convinced something has, recently.  But, as far as I can tell 
from my tests, I think you are right in saying it was not AUCTeX.

I have, and can gladly report the issue is gone on my side with the fix. 
Thank you very much.

Gustavo.

No no, the error comes from emacs complaining that it cannot set the
working directory for the shell to a directory which doesn't exist.

I just checked with an emacs 22 installation.  You get the very same
error there.

That's all that matters. :-)
