Re: [AUCTeX] inverse search when comipling only part of the document

[Jonas Frey]

Thanks a lot for your answer -- it almost works!

I copied the definition that you gave to my .emacs, and now when inverse searching, the cursor jumps to the right line in both files (source file and region file), but it still activates the buffer with the region file.

How can I have the source file active after inverse search?

I think this should work--it has worked on the few tests I have done, but I haven't used it for very long.  Let me know if you have any problems.

(defadvice server-goto-line-column (after server-visit-region.tex
                                         (line-col)
                                         activate)
 "When visiting a file from an external source, make sure that we
are not narrowed, since the external source almost certainly
uses absolute file line numbers."
 (when (string-match "_region_.tex\\'" (buffer-file-name))
   (save-excursion ;; in case we don't find the other file we at least want the right line...
     (if (re-search-backward
          "\message{ !name(\\([^)]+\\))\\(?: !offset(\\([-0-9]+\\))\\)?\\s *}" nil nil)
         (let ((file-name (match-string 1))
               (offset (match-string 2))
               (line (car (ad-get-arg 0)))
               (col (cdr (ad-get-arg 0))))
           (if offset (setq line (+ line (string-to-number offset))))
           (find-file file-name nil)
           ;; Ironic, but I think cleaner then reimplementing...
           (server-goto-line-column (cons line col))
           (message "Moved from _region_.tex to line %s of %s." line file-name))

       ;; else
       (message "This is _region_.tex, but I couldn't find the original file!")))))
