Magit

Magit is an interface created for Git, a version control system. Magic is implemented as an Emacs package and currently aspires to become a complete Git porcelain. Although it doesn't improve and wrap around every Git command yet, it is still complete enough to let Git users do nearly all of their version control tasks inside the Emacs system. Magit is basically an enhanced version of Git. It has several features and attributes that make it a workable and easily accessible tool. You can do simple tasks like commits without needing to leave the editor. There's also easily-remembered mnemonics for the most common tasks, so you won't constantly need to peruse a reference guide. You can use these mnemonics to speed up your workflow. It has a better visualization and better interactive flow capabilities than Git. Because Magit is integrated with Emacs, it's very easy to fix diffs. As soon as a file comes up in the status view or the logs, you can access it immediately, instead of needing to dig for the files you want to fix. There are multiple buffers utilized in order to show contextual information. In Magit, it's also very easy to stage a hunk. It's even easy to stage small parts of a hunk. There are several "apply variants" available on top of the staging and unstaging variants. You can view blame information inline with the file rather than needing to page back and forth between the two, which saves valuable time and energy. There are powerful rebasing capabilities. Magit is also available in Homebrew; all you need to do is use the "brew install magit" command. Magit has a large number of support features available through the web. There's a comprehensive FAQ on the Magit website which covers common debugging and troubleshooting problems. If you don't find your problem there, you can peruse the list of open issues and use the search tool to find resolved issues. There's a manual to learn the program initially, and it makes an excellent reference guide. Magit is completely free to use. The developers keep the application running through the use of donations.
