Minimum requirements

• helm
• git

Optional requirements

• wgrep

  wgrep enable a grep buffer editable and apply those changes to the file buffer.

(require 'helm-git-grep) ;; Not necessary if installed by package.el
(global-set-key (kbd "C-c g") 'helm-git-grep)
;; Invoke `helm-git-grep' from isearch.
(define-key isearch-mode-map (kbd "C-c g") 'helm-git-grep-from-isearch)
;; Invoke `helm-git-grep' from other helm.
(eval-after-load 'helm
  '(define-key helm-map (kbd "C-c g") 'helm-git-grep-from-helm))

Basic usage

M-x helm-git-grep

Helm git grep. if submodules exists, grep submodules too.

M-x helm-git-grep-at-point

Helm git grep with symbol at point. if submodules exists, grep submodules too.

Action	Description
Find file	Jump to result.
Find file other frame	Jump to result in other frame.
Find file in Elscreen	Jump to result in elscreen.
Save results in grep buffer	Save helm git grep result in a grep-mode buffer.
Find file other window	Jump to result in other window.

Advanced usage

Keymap helm-git-grep-map

These commands are available when executing incremental [git grep] by helm-git-grep.

For more information about keymap, execute C-c ? helm-git-grep-help.

Key	Command	Description
C-z	helm-git-grep-persistent-action	Persistent action. With a prefix arg record candidate in mark-ring.
C-c C-o	helm-git-grep-run-other-frame-action	Jump to result in other frame.
C-c e	helm-git-grep-run-elscreen-action	Jump to result in elscreen.
C-x C-s	helm-git-grep-run-save-buffer	Save helm git grep result in a grep-mode buffer.
C-c o	helm-git-grep-run-other-window-action	Jump to result in other window.
C-c i	helm-git-grep-toggle-ignore-case	Toggle ignore case option.
C-w	helm-yank-text-at-point	Yank text at point in invocation buffer into minibuffer.
C-c ?	helm-git-grep-help	Help command for helm-git-grep.
M-<down>	helm-goto-next-file	Go to precedent file in helm git grep buffers.
M-<up>	helm-goto-precedent-file	Go to next file in helm git grep buffers.

C-c i helm-git-grep-toggle-ignore-case

A buffer name is *helm git grep* without ignore case option.

Customization

Variables

helm-git-grep-sources

(Default: '(helm-git-grep-source helm-git-grep-submodule-source))

Default helm sources for helm-git-grep.

If you don't want to search in submodules, Set only helm-git-grep-source like this:

(setq helm-git-grep-sources '(helm-git-grep-source))

helm-follow-mode-persistent

Please set helm-follow-mode-persistent to non-nil if you want to use helm-follow-mode by default.

You must set it before loading helm-git-grep.el.

(custom-set-variables
 '(helm-follow-mode-persistent t))

helm-git-grep-candidate-number-limit

(Default: 300)

Limit candidate number helm-git-grep.

helm-git-grep-max-length-history

(Default: 100)

Max number of elements to save in helm-git-grep-history.

helm-git-grep-use-ioccur-style-keys

(Default: t)

Use Arrow keys to jump to occurrences.

helm-git-grep-ignore-case

(Default: t)

Ignore case when matching.

helm-git-grep-at-point-deactivate-mark

(Default: nil)

Deactivate the mark when helm-git-grep-at-point is invoked.

helm-git-grep-base-directory

(Default: 'root)

Base directory for search by git-grep(1).

Possible value are:

• root: git root directory
• current: current directory (default directory of current buffer)

helm-git-grep-pathspecs

(Default: nil)

Pattern used to limit paths in git-grep(1) commands.

Each pathspec have not to be quoted by singe quotation like executing git command in inferior shell. Because helm-git-grep run git command by start-process, and start-process is not executed in inferior shell. So, if pathspec is quoted by singe quotation, pathspec can't work in git-grep(1) by helm-git-grep.

For more information about pathspec, See pathspec in Git gitglossary Documentation.

If there is something wrong about pathspec configuration, you can check limit paths by pathspec using helm-git-grep-ls-files-limited-by-pathspec.

helm-git-grep-file
