Before doing so, let me clarify my motivation and ask for some advice. I (and at least 6 others) have been using the package https://github.com/ultronozm/czm-preview.el, which implements this fix together with some other features. The implementation relies on 10 pieces of advice applied to preview-* and TeX-* functions. I'd like to eliminate the use of advice, so that the package is less brittle. Fixing this bug would be one step towards that goal; the others would involve adding hooks and customization options to preview.el (without modifying its current operation -- I don't want to introduce instability). Thus, to create this patch, I'll isolate the relevant modifications from my overridden versions of preview-region and preview-parse-messages. Later, in a separate report, I'll ask for some (e.g.) hooks to be added to the same functions. If those changes make it into an AUCTeX release, then I'll be able to eliminate some advice from my package. Does this sound like a reasonable plan? Any other suggestions? Thanks, best, Paul

I'd just add -file-line-error to the options you are calling TeX with.
That makes for more reliable error message interpretation.

Emacs : GNU Emacs 29.0.50 (build 3, x86_64-apple-darwin21.6.0, NS
appkit-2113.60 Version 12.6 (Build 21G115))
of 2022-11-06
Package: 13.1.10
Take the following document:
#+begin_src latex
\documentclass{amsart}
\begin{document}
$x$ $x$
\end{document}
#+end_src
Run ~preview-region~ on the region consisting of the first $x$. This works
as expected.
Next, run ~preview-region~ on the region consisting of just the second
$x$. This does not preview the second $x$. Instead, it refreshes the
overlay on the first $x$.
The relevant output:
#+begin_quote
./_region_.tex:5: Preview: Snippet 1 started.
<-><->
l.5 $
x$
Preview: Tightpage -32891 -32891 32891 32891
./_region_.tex:5: Preview: Snippet 1 ended.(282168+0x374556).
<-><->
l.5 $x$
#+end_quote
The issue here is that there's not enough context for
~preview-parse-messages~ to determine which $x$ to overlay.
One workaround would be to apply ~preview-region~ to a region containing
both $x$'s (or to use ~preview-buffer~, etc). This workaround wasn't ideal
for my use-case (see parenthetical comment at the bottom).
I think a fix would be to store the beginning of the region being previewed
in a buffer-local variable and, if needed, bump the point when searching
for where to place the overlay. Details:
- Add the following line somewhere in preview.el:
#+begin_src elisp
(defvar-local preview-region--begin nil "Start of region being
processed.")
#+end_src
- Add the following line to ~preview-region~, just before the invocation of
~preview-generate-preview~:
#+begin_src elisp
(setq-local preview-region--begin begin)
#+end_src
- Add this to ~preview-parse-messages~, just before the second ~cond~ block:
#+begin_src elisp
(when (< (point) preview-region--begin)
(goto-char preview-region--begin))
#+end_src
I've made these changes in my local version and they have worked for me.
(This bug was an issue for me because I had set up a timer that searches
the visible portion of a TeX buffer for unrendered math environments and
runs ~preview-region~ on contiguous unpreviewed blocks. This led to many
situations where ~preview-region~ was called on math regions, such as the
second $x$ in the above example, that had already been previewed in the
current line. My original workaround was to enlarge the region sent to
~preview-region~ to contain any repeated math regions that appear earlier
in a given line. This worked, but often resulted in many fragments getting
unnecessarily refreshed.)
