A local variable keeps coming back, and I know not whence. In a certain buffer, TeX-command-extra-options is "--synctex=1", even after I have removed this from my init.el and restarted Emacs. I tried setting it to something else by adding

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-command-extra-options: "--output-directory=out/"
%%% End:

to the end of the file. But, if I save and revert, the old value persists. If I setq the variable manually, and revert the file, the old value comes back. This doesn't happen with emacs -Q, but I was hoping someone might know what is going on. I suspect that AUCTeX is somehow responsible.

Alternative question: how might I debug this? It seems to me that, when I revert, the variable is first set according to my specification, and then reset by something or other.

  • Is `TeX-command-extra-options` a user option? If so, have you customized it, so it gets set automatically in your init file or your `custom-file`? – Drew May 21 '19 at 15:45
  • @Drew, no, I don't load the custom-file. – Toothrot May 21 '19 at 16:00
  • OK, for some reason there is a directory called auto/ containing code that is run automatically. – Toothrot May 21 '19 at 17:34
  • Glad you found the problem. You can accept your own answer. (An accepted answer improves the usefulness to others of a Q & A.) – Drew May 21 '19 at 18:39

In case someone else runs into this, I had enabled TeX-auto-save, which saves settings to an auto/ directory and loads them when a file is revisited.
