Hi all,
the function `reftex-TeX-master-file' in `reftex.el' has support for
subfiles package, but I think the regexp there does not match all
cases. Please consider a main file "subfile-main.tex" and a sub-file
"subfile-sub1.tex" like these:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{subfiles}
\begin{document}
\section{Section 1}
\label{sec:section-1}
\subfile{subfile-sub1.tex}
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---
--8<---------------cut here---------------start------------->8---
\documentclass[subfile-main.tex]{subfiles}
\begin{document}
\section{Subsection 1}
\label{sec:subsection-1}
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---
`reftex-TeX-master-file' fails to parse the first line and find out the
main file due to first part of it:
--8<---------------cut here---------------start------------->8---
(defun reftex-TeX-master-file ()
;; Return the name of the master file associated with the current buffer.
;; When AUCTeX is loaded, we will use it's more sophisticated method.
;; We also support the default TeX and LaTeX modes by checking for a
;; variable tex-main-file.
(let
((master
(cond
;; Test if we're in a subfile using the subfiles document
;; class, e.g., \documentclass[main.tex]{subfiles}. It's
;; argument is the main file, however it's not really the
;; master file in `TeX-master-file' or `tex-main-file's
;; sense. It should be used for references but not for
;; compilation, thus subfiles use a setting of
;; `TeX-master'/`tex-main-file' being themselves.
((save-excursion
(goto-char (point-min))
(re-search-forward
"^[[:space:]]*\\\\documentclass\\[\\([[:word:].]+\\)\\]{subfiles}"
nil t))
(match-string-no-properties 1))
--8<---------------cut here---------------end--------------->8---
The regexp looks for [:word:] character class and ignores anything
else. Using `-', `_' or digits in main file name will not work. I
think the regexp can be reduced to
--8<---------------cut here---------------start------------->8---
(re-search-forward
"^[[:space:]]*\\\\documentclass\\[\\([^]]+\\)\\]{subfiles}"
nil t))
--8<---------------cut here---------------end--------------->8---
as `reftex-TeX-master-file' checks if .tex extension is given or not.
With this change, one can use `C-c )' over all files in a project and
`C-c C-c' compiles a only subfile when issued in it.
Any comments? I would prepare a patch after confirmation here.
Best, Arash

Thanks, I close this one then.
