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

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. 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: M-x git-gutter:next-hunk or M-x diff-hl-next-hunk.

Highlight diffs

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)

Browse and stage hunks with Helm

Helm-hunks allows to jump around git hunks with helm, to preview them on the fly, and to stage them.

Colorize Dired output depending on the file git status

See emacs-dired-k, that does like the k zsh utility.

Commit on every change

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 git-timemachine. Once you have called M-x 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.

Libraries

Git.el: information, predicates and actions on your git repo

With git.el, we have information about our repo: a list of remotes, of branches, staged files, untracked ones, etc, and also predicates (is there a branch called this ? a tag called that ?), local actions (add, branch etc) and non-local ones (clone, etc).

Read and write the git config

See gitconfig.el to have functions that can read and write the git config file.
