[AUCTeX] C-c ` pops to *output* buffer

[David Reitter]

I wonder if the valued AUCTeX experts could shed some light on an  
issue with C-c ` (TeX-next-error).

This pops to the *output* buffer (with the complete compile log) first  
and then switches to the more informative error message (*TeX Help*).

This works well, unless a configuration is used that will display  
newly popped-up buffers in separate frames, for instance with `one- 
buffer-one-frame-mode' (Aquamacs), but presumably also with `pop-up- 
frames' set to t.
What happens then is wholly different from the normal behavior: the  
*output* buffer is shown in the background  (separate frame), and then  
the *Help* buffer is shown as well.

I notice that `TeX-parse-TeX' does the `pop-to-buffer' call in  
question, and it needs to do so for `TeX-error-point' to be defined  
and the parsing to work.

If I change the function as below (temporarily setting (TeX-active- 
buffer), which is *output*), then things work as intended. But  
presumably I've broken something else.

What is the intention of `pop-to-buffer' in this place, and why does  
AUCTeX need to visibly pop to the other buffer before actually  
bringing up the *Help*?




(defun TeX-parse-TeX (reparse)
  "Find the next error produced by running TeX.
Prefix by C-u to start from the beginning of the errors."

  (let ((old-buffer (current-buffer))
        (default-major-mode major-mode))
    (with-current-buffer (TeX-active-buffer)
    (if reparse
        (TeX-parse-reset))
    (goto-char TeX-error-point)
    (TeX-parse-error old-buffer))))
