Zakkak: /* Highlight diffs */ FIx typo "that git-gitter" -> "than git-gutter"

Packages to interfere with the '''git''' version control system.

= Full interfaces =

== Magit ==

'''Magit''' is a great Emacs mode for working with Git repositories. It provides a convenient interface for the most common Git operations. Please visit its own [[Magit]] page.

= Specific use cases =

== Git blame ==

'''Git-blame''' is a package, available in [[ELPA]], which provides a minor mode for incremental blame.

== Show last commit message for current line ==

This package provides a function called '''git-messenger:popup-message'''
that when called will pop-up the last git commit message for the
current line. This uses the git-blame tool internally.

Available in ELPA.

== Highlight uncommited changes ==

=== Git gutter ===

[https://github.com/syohex/emacs-git-gutter Git-gutter] is an extension to highlight uncommitted changes on the left side of the window, indicating wether a line has been inserted, modified or deleted, and allowing you to jump between and revert them selectively. [https://github.com/dgutov/diff-hl diff-hl] does it too and works with Git, Mercurial, Bazaar and Svn, and it provides similar functionnality for '''dired'''. Both are available in [[ELPA]]. They are [[Tramp]]-aware.

After installation, call the minor modes or enable them:

(add-hook 'python-mode-hook 'git-gutter-mode)

==== Jump between changes ====

To jump between changes: {{Command|git-gutter:next-hunk}} or {{Command|diff-hl-next-hunk}}.

=== Highlight diffs ===

[https://github.com/dgutov/diff-hl Diff-hl] goes a little further than git-gutter in that it can highlight the uncommited diffs, even from [[Dired]]. And we can get them on the fly while we type:

(diff-hl-flydiff-mode)

== Commit on every change ==

[http://melpa.org/#/git-auto-commit-mode git-auto-commit-mode] (on MELPA) is a minor mode that tries to commit a change to a file after every save. It can also push automatically.

== See previous versions of file ==

It's very easy with [https://github.com/pidu/git-timemachine git-timemachine]. Once you have called {{Command|git-timemachine}} you'll have the keys:

* '''p''' Visit previous historic version
* '''n''' Visit next historic version
* '''w''' Copy the abbreviated hash of the current historic version
* '''W''' Copy the full hash of the current historic version
* '''g''' Goto nth revision
* '''q''' Exit the time machine.
