Question

I was wondering if there was an easy way to extend Git commands.

So I could create commands like:

git my-custom-made-extension --my-options <my-other-arguments>

In a perfect world, I would be able to do it in any language it pleases me and I would be able to add my custom made extensions to any development environment fairly easily.

Let’s say, something like the support of plugins in Vim?

Answer 1

As you can see in the source code in execv_dashed_external, If you make the command git-my-custom-made-extension, then git will alias:

• git my-custom-made-extension ... → git-my-custom-made-extension ...
• git help my-custom-made-extension → man git-my-custom-made-extension

There’s nothing special about “extending git”. Just build a program as you would normally, and make sure the name starts with git-.
