wgrep allows you to edit a grep buffer and apply those changes to
the file buffer like sed interactively. No need to learn sed
script, just learn Emacs.
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 regardless of whether or not buffer is read-only.
(setq wgrep-change-readonly-file t)
- wdired.el like interface.
- Support GNU grep
--context(-A-Band-C) option. - Can handle too many files.
- Can handle newline insertion in grep buffer.
- Delete whole line include newline.
GNU sed helm-ag has a similar feature.
This program was forked from Matsushita Akihisa's grep-edit.el v2.11. As this website is now inaccessible, emacswiki.org's copy may be consulted.
Imported version can be downloaded from this orphan commit: https://github.com/mhayashi1120/Emacs-wgrep/tree/import-original-author/
Following added implementations and differences.
- Support GNU grep context option -A -B and -C
- Some bugfix. (wrong coloring text etc..)
- wdired.el like interface.
- Remove all advice.
- Bind to local variables. (grep-a-lot.el works well)
- After save buffer, colored face will be removed.
- Change face easy to see.
- Reinforce checking error.
- Support removing whole line include new-line.
