To install this package, run in Emacs:
M-x package-install RET wgrep RET
## Summary: 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. ## Install: Put this file into load-path'ed directory, and byte compile it if desired. And put the following expression into your ~/.emacs. (require 'wgrep) ## Usage: 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) ### Trivial features: - wdired.el like interface. - Support GNU grep `--context` (`-A` `-B` and `-C`) option. - Can handle too many files. - Can handle newline insertion in *grep* buffer. - Delete whole line include newline. ### Similar softwares: [GNU sed](https://www.gnu.org/software/sed/) [helm-ag](https://github.com/syohex/emacs-helm-ag) has a similar feature. ## History: This program was forked from Matsushita Akihisa's [grep-edit.el v2.11](http://www.bookshelf.jp/elc/grep-edit.el). As this website is now inaccessible, [emacswiki.org's](https://www.emacswiki.org/emacs/grep-edit.el) 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.
