Open many buffers

Open many buffers

[Andrea Crotti]

I don't see in the emacs functions anything like
"visit-all-the-buffers-matching-this-regexp".

It would be useful sometimes, now I use something like this in the git
projects

--8<---------------cut here---------------start------------->8---
(defun open-git-files ()
  "Visit all the files in the current git project"
  (interactive)
  (dolist
      (file (split-string (shell-command-to-string "git ls-files")))
    (message "Opening %s" file)
    (find-file file)))
--8<---------------cut here---------------end--------------->8---

But it opens too much often.

Something that
- ask for a regexp
- visit all the buffers
- automatically set up a guessed best way to place them on the frame (or
  maybe creates a new elscreen for each one for example)

Is there anything like this somewhere?

Here are two possibilities:

1. Ibuffer: `% n rgx RET v'  where rgx is your regexp.

`% n' marks regexp matches.  `v' visits.

2. Icicles: `C-x b rgx  S-TAB  C-!'  where rgx is your regexp.

`S-TAB' regexp-completes.
`C-!' acts on each of the completion candidates.

The action in this case is `C-x b': visit a buffer.

Here's a third possibility: using Dired, mark according to a regexp

% m regexp RET

then open (find) those marked files using `F'.

That works only for files, not buffers unassociated with a file.

That's why I mentioned Ibuffer (though I don't use Ibuffer myself).
It is similar to the Dired approach, but for buffers, not files.

Not a regexp, but wildcard patterns:

C-x C-f *.c RET
