Re: Parse graphicspath for searching [

[Leo Stein]

I saw multiple style files using `TeX-auto-add-regexp', but sorry, I don't understand how this is related to multi-file documents. If this is explained clearly somewhere in the documentation, please let me know, but I haven't found it yet.

No, this has nothing to do with RefTeX, it's exclusively AUCTeX's
business to cater for completion candidates of graphics files.

I think the easiest way is to plug this into AUCTeX's parsing abilities.
Search the files under style/ directory for `TeX-auto-add-regexp' and
you will get a lot of examples.  But since parsing in AUCTeX is
expensive reg. regexp groups, you should make this addition conditional
and provide a custom variable for users who want to enable this feature.
