Hi all,
Steps to reproduce:
- Emacs -Q, recent master.
- AUCTeX main branch.
- Visit a minimal TeX file, e.g.:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
Let $x$ and $y$.
\end{document}
--8<---------------cut here---------------end--------------->8---
- Disable TeX-PDF-mode.
- Ensure preview-image-type is not dvi* (e.g., use the default, png).
- M-x preview-buffer (C-c C-p C-b).
This gives the backtrace:
Debugger entered--Lisp error: (file-missing "Opening input file" "No such file
or directory" "~/doit/_region_.prv/tmpGUZRjz/pr1-1.png")
preview-reraise-error()
preview-gs-filter(#<process Preview-Ghostscript> "GS>")
>From *_region_ output*:

This regression seems to have been introduced in
1925629dbe811452deeab45b98e290936bec9555 in
preview-dvi*-process-setup-1, where the PS-FILE slot is hardcoded to t.
That seems correct for dvi*, but not for dvips+gs, where this slot
previously held preview-ps-file (after running preview-start-dvips).
The attached patch restores that behavior while keeping the dvi* path
unchanged. Any thoughts?
Thanks, best,
Paul
