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 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 | http://melpa.org/#/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.

Interfaces to github

Clone a github repo

Github-clone (in MELPA) is a project to clone a github repository. The command M-x github-clone will prompt for a repository and directory to clone to. In one shot, it will use the github api to fork the repo if you are not the owner, clone the repo to the specified directory, and add a remote called upstream if the repository is a fork.
