This was just what I was looking for! Thanks!

I notice you’re a fan of using setq to add to customizable variables.
Why not M-x customize-group or M-x customize-variable the variables.

That way people could get in the habit of working with, instead of against the customize interface.

What do you think?

What I meant was the package manager offers a package “all” which you have to install. Load it with M-x all-mode and use the command “all” like you would “occur”.

The package manager in Emacs 24 (M-x list packages) comes with all-mode which I think is what you’re looking for.

mickey: I don’t understand what functionality you’re referring to.

If you’re talking about the

open-line

then that functionality is still preserved since the code given by Anselm (thanks for the tip btw, I didn’t knew isearch provided that function in a easy to use wrapper) since it only binds the

C-o

combination when you are already inside a search.

I just tried in my emacs (with the

-Q

flag) and

C-o

doesn’t seem to do anything while searching, except to quit the search and call

open-line

Do you have anything else bind to

C-o

in the

isearch-mode-map

? Because I’m always on the lookout for things others find “too useful” in emacs.

I think the default functionality provided by C-o is too useful to be overriden. A better choice might be the less useful M-o face stuff.

I used that code for a long time, too, but it's now much easier. If you prefer C-o as a key binding, you could strip that down to:

(define-key isearch-mode-map (kbd "C-o") 'isearch-occur)

Instead of using M-s o, I find it easier to use C-o which can be accomplished with this piece of code:

(define-key isearch-mode-map (kbd "C-o")
  (lambda () (interactive)
    (let ((case-fold-search isearch-case-fold-search))
      (occur (if isearch-regexp isearch-string (regexp-quote isearch-string))))))

I think I found it in technomancy's emacs start kit and I use it all the time.

“My only complaint about occur is that it does not let you quickly search a set of buffers that match a specific major mode — arguably a common use case if you’re a programmer”
To do this, I first use ibuffer to select/filter the buffers I’m interested in, then run occur directly from the *ibuffer* buffer using the ‘O’ key binding.

Here it is:

(defun occur-multi-occur ()
  "Starts multi-occur for the current search term on all buffers with the first matching buffer's major mode."
  (interactive)
  (multi-occur 
   (get-buffers-matching-mode 
    (with-current-buffer (car (nth 2 occur-revert-arguments))
      major-mode))
   (car occur-revert-arguments)))
(define-key occur-mode-map "m" 'occur-multi-occur)
