apropos search

apropos search

[sable]

Hi,
When you're doing an apropos search, is there a way to tell Emacs to
search for "whole words only". E.g, if you use the keyword "change"
and you only want command names that contain the word change, and not
"changes" or "exchange".
Thanks,

C-h a \<change\> RET

Interesting, thanks. Is there a way (variable) to change the default
search to "whole words only"?

I don't think so, but we can try to create it.

(defcustom apropos-whole-words t
  "Whether the apropos commands should search for whole words."
  :group 'apropos
  :type 'boolean)

(defadvice apropos-parse-pattern (before rewrite-pattern-ad activate)
  (when (and apropos-whole-words
             (consp (ad-get-arg 0)))
    (ad-set-arg 0 (mapcar (lambda (p)
                            (format "\\<%s\\>" p))
                          (ad-get-arg 0)))))

Whoa, that's a little over my head at this point, but I'll keep that
for future reference, thanks! I assume you would put this code in
the .emacs file or something...
