[CEDET-devel] conditionally disabling semantic

[<ry...@ds...>]

Hi all,

I use pcl-cvs (aka pcvs in emacs 21) daily.  I use the cvs-mode-idiff
differencing command dozens if not hundreds of times each day.
Hence the extra 3 or 4 second delay that semantic causes while it
parses files cvs-mode-idiff loads for differencing purpose was too
much for me especially since these files are used only for
differencing and nothing else.

So I wrote the code below to conditionally suppress semantic on
temporary files.  I tracked semantic-activate-mode-bindings down by
starting with semantic-post-change-major-mode-function which was in
find-file-hook list.

What do you think?  Is there a better way?  Should something like this
be a part of semantic?


(defadvice semantic-activate-mode-bindings
  (around suppress-tmp-files activate compile)
  "Don't setup semantic for tmp files such as files CVS loads for the 
purpose of differencing."
  (cond
   ;; Bypass files loaded by CVS for differencing.
   ;; This doesn't work on files retrieved with explicit version numbers.
   ((string-match "\\.\\(HEAD$\\|BASE\\)$" (buffer-name))
    ;; Hmm.  I thought the line below would not be needed at first,
    ;; because bypassing the body of semantic-activate-mode-bindings
    ;; would not setup semantic variables.  But this advice does not
    ;; work without the line below. -ryk2/23/03.
    (setq semantic-toplevel-bovine-table nil))
   (t ad-do-it)))
