[Message part 1 (text/plain, inline)]

Hi,

Please ignore my previous email... Here is the bug report...


Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

Hi,

I'm using AucTeX for years now...

I'm using emacs "26.3 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.11)" and AucTeX 12.2.0 (installed from MELPA) on XUbuntu 19.10.

According to doc[1] (and years of usage...), hitting `C-c C-f C-<x>` should insert (`\text<xx>{yyy}`). e.g. `\textsc{yyy}`

However, on my machine, AucTeX randomly inserts font commands in old TeX style (`{\xx yyy}`) or modern one (`\text<xx>{yyy}`).

I have absolutely no clue why the behaviour is not consistent accross all .tex files, nor why it does not respect the documentation (always using modern syntax)....

PLEASE HELP!!!! This randomness is REALLY getting on my nerves!!! How can I get back a consistent behaviour???

Hi Guillaume, sorry for late response.

I suspect that the value of the variable `TeX-font-list' is not updated
in some of your buffers.  Could you examine the value of `TeX-font-list'
in the buffer where old TeX style command {\xx yyy} is inserted?

Hi Guillaume,

Then I guess that it's worth trying to add
%%% Local Variables:
%%% mode: latex
%%% End:
to the end of your LaTeX files.  If you devide your documents into some
child files using \input or \include, you can instead add a line
% -*- mode:latex -*-
as first line of the child files.

Regards,
Ikumi Keita

I think that simple shell script will do the job, if you have a lot of
LaTeX document files.

No further comments, therefore I'm closing this report.
