Open included files in emacs+AUCTeX

Question

When working with emacs+AUCTeX I would like to consider a project with one main.tex in which you have many include's. Is it possible somehow to open the included files from within the buffer where main.tex is loaded? Somehow make emacs understand that

\include{./path/to/foo}

in main.tex is a filename (with relative path) and open it either by clicking on it or hitting some keybinding when the courser is within the curly brackets?

A "bonus" question is probably the next step, that is to have some integrated "project manager" in emacs, where the included files are listed and one can browse the projects components. Does it sound reasonable? feasible? Any ideas?

Answer 1

I use find-file-at-point. It also works for #includes in C, sometimes imports in Python, URLs, etc.

(global-set-key (kbd "C-x f") 'find-file-at-point) ;; I hardly ever set the fill-column

Answer 2

With reftex, C-c = will open a little table of contents. Once you've compiled the document, reftex should include the section headings of included files. You can use this menu to open included files. Indeed, if you press enter on a particular section, reftex will open the included file and put the pointer at the beginning of that section.

Answer 3

If you have the included file with a specified TeX-master at the end, emacs/AUC-TeX automatically loads the corresponding "main.tex", too (at least with my version). Of course, this is not quite what you want, but I think it is a good idea to set the TeX-master for the child files: you can also compile them directly and emacs invoces the pdflatex on the correct main file etc.

For the "browser" thing, I use "speedbar" which gives you a list of all files in the directly (tree-like) and you can easily jump to sections/subsections etc inside the files.
