isearch and M-x occur questions(several)

isearch and M-x occur questions(several)

[Javier Oviedo]

Hello all:

I'm running emacs 21.2.1 on WindowsXP.

I have just discovered "M-x occur" and like it very much.

1.  Is there a way, or an already existing package, to combine isearch and
occur. What I like about occur is the window that lists the line number and
matching expression. Is there a way that isearch could do something similar?
I like the ability to quickly run through all matches in isearch using
isearch-forward, but would also like the option of having that window simply
show me all lines with matches.

2.  Can the occur-mode window, which lists all line with matching
expressions, display the line in the particular font-lock-face for the mode
of the file being searched? For example, if my expression happens to exist
in a C function prototype, the occur-more window would show that line with
the appropriate c-mode faces.

3.  Can occur highlight the matching expression in the occur-mode window?

I hope that my questions make sense. Thanks in advance.

Please ignore question numbers 2 and 3. Occur-mode already handles these
issues.

Maybe M-x occur RET could default to (regexp-quote
THE-LAST-ISEARCH-STRING).  But this is unimplemented.

Another useful thing might be to bind a key in isearch-mode-map that
runs occur with the right options.

I like that.

(defun isearch-occur ()
  "Run `occur' with current isearch string."
  (interactive)
  (let ((case-fold-search isearch-case-fold-search)
	(search-string (if isearch-regexp
			   isearch-string
			 (regexp-quote isearch-string))))
    (occur search-string)))

(define-key isearch-mode-map [(control o)] 'isearch-occur)

I like it too.   I didn't know of occur.   Thanks!

I like that idea quite a bit. I will test it out. Thanks.
