Subject: 13.1.3; aspell does not work in AUCTeX buffer
Date: Sat, 30 Apr 2022 08:48:04 +0200

I'm using aspell with Emacs. When I try to do spell checking in a LaTeX
file (e.g. ispell-word) I keep getting the error message "No Ispell
process to read output from!"

I can't tell if it's an AUCTeX bug. But aspell works as expected with
.txt files in text-mode. The reported error occurs only in latex-mode.
That's why I'm reporting it here.

Any ideas what could go wrong?

Many thanks
Uwe

A similar issue was reported last August[1], but it didn't get resolved.

There were reports of another type that aspell crashes (or freezes) on
TeX buffer[2][3].

All these issues are on windows, so I guess something is broken in the
implementation of "tex mode" of ispell which only appears on windows. In
the thread [3], Brian told me that

... oh I realized now that he sent this message as private reply, not as
group reply, so this information wasn't recorded in the archive...

I can confirm that commenting this line in ispell.el also helps in my
case. Meanwhile (in the Emacs 28.1 release) it's line 4056.

Best regards,
Uwe

IIUC the only place where the error can occur is in the function
`ispell-accept-output'.  Maybe you can Edebug the function, trigger the
issue and see what's going wrong.  The question is if this an ispell.el
issue, then we can assign your report to Emacs, otherwise maybe to
aspell itself.

Best, Arash
