wgrep allows you to edit a grep buffer and apply those changes to the file buffer.
Put this file into load-path'ed directory, and byte compile it if desired. And put the following expression into your ~/.emacs.
(require 'wgrep)
You can edit the text in the grep buffer after typing C-c C-p.
After that the changed text is highlighted.
The following keybindings are defined:
C-c C-e: Apply the changes to file buffers.C-c C-u: All changes are unmarked and ignored.C-c C-d: Mark as delete to current line (including newline).C-c C-r: Remove the changes in the region (these changes are not applied to the files. Of course, the remaining changes can still be applied to the files.)C-c C-p: Toggle read-only area.C-c C-k: Discard all changes and exit.C-x C-q: Exit wgrep mode.
To save all buffers that wgrep has changed, run
M-x wgrep-save-all-buffers
To save buffer automatically when `wgrep-finish-edit'.
(setq wgrep-auto-save-buffer t)
You can change the default key binding to switch to wgrep.
(setq wgrep-enable-key "r")
To apply all changes wheather or not buffer is read-only.
(setq wgrep-change-readonly-file t)
