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