Welcome back.

May I ask which package you want to use where AUCTeX support for completion is missing?  I'm asking because TeX-auto-generate\(-global\)? can produce completion files which are not really accurate.  So if you want to use a specific package where the AUCTeX style package.el is missing, it's better to write it yourself or ask here for help.

SD> I am using the Language Science Press (for xetex) langscibook class, and when starting, I could not complement on commands defined in that class and other packages loaded in a local file \input{localpackages.tex}.  I had to update langscibook, and after that I thought I should create the AUCTeX style files for my packages, which is when I started to try to invoke TeX-auto-generate-global.

SD> So you tell me that invoking TeX-auto-generate-global is actually not necessary?  But as far as I can see, the AUCTeX-style-files do cover only a part of all packages provided with LiveTeX.

SD> And So it is normal that it fails on so many files with the error "TeX-auto-parse-region: Wrong type argument: stringp, nil"?  This seems very weird to me...

This is what I see after `list-packages':

Package auctex is available.

Strange.  How did you install the package?  With `M-x list-packages RET', choosing AUCTeX with 'i' and 'x'?

SD> yes, I used `M-x list-packages RET', searched for AUCTeX with C-s, and then entered the package and chose "install".  I am not sure whether I saw the "obsolete" description the first time I searched for the package or only the second time.
