git - how?

draft…

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

“Talk is cheap. Show me the code.”

– Linus Torvalds

History

On 3 April 2005, Linus Torvalds began the development of git, after many Linux kernel developers gave up access to BitKeeper. Just 3 days after, on 6 April, Torvalds announced the project. And the next day, it became self-hosting.

On 26 July 2005, Linus Torvalds turned over git’s project maintenance to Junio Hamano. Hamano is the project’s core maintainer since.

Workflow

The basic/usual git workflow is the following:

  • Create/clone a git repository, all your work is done in this Working Directory.
  • Once your work reaches your goal, your changes are added to the Staging Area.
  • Now your Staging Area contains everything you want to commit, you can save changes to the git repository.

Improved (maybe) indenting on save

I realized that sometimes identing the whole buffer might not be the desired output. That because if the file is on different identation, your git commit might be hard to follow. Because of that I studied a bit emacs lisp and came up with similar idea. On …
