One of my favorite things to do is automate my workflows. When it comes to version control, Git makes this extremely easy to do by allowing it to be extended.
So, what does it mean to extend Git? Simply put, it’s extending Git’s behavior to do anything you would like. Effectively, it’s adding programs written in any language and invoking them as if they were Git built-ins.
For example, everyone knows
git pull and
git push. I’ve extended Git to also do
git hub and
git bootstrap, as well as
git dirty (well, technically that’s an alias, but you get my point).
How is this done? There are only three simple rules:
Create your script in a file called
scriptnameis obviously a placeholder for, well, the name of the script :)
Make the script executable.
Place the script in your
Say what? Yeah, it’s really that easy. But you will look like a hero to your peers!
All of my Git extensions are shell scripts, but you can use any scripting language you’d like that’s on the system.
Let’s go further and create your own man pages for these extensions.
Wouldn’t it be dynamite to create and install your own man pages? Wouldn’t it be sweet to do
man git-hub? Yes!
You can do this in four easy steps:
pod2manpackage using your package manager.
.podfile. It’s easy to create, just use one of mine as a template to create your own.
For example, create
=head1 NAME git-hub - Open any file, directory or commit on GitHub in regular view or blame view. =head1 SYNOPSIS git hub [ -f, --file file ] [ -b, --branch branch ] [ --range 'L10-L20' ] [ --get-hash hash ] [ --hash hash ] [ --blame ] =head1 EXAMPLES git hub - Opens the current working directory. git hub --file grid/filters/filter/List.js - Opens the file. git hub -f grid/header/Container --blame - Opens the file in a blame view. git hub --branch extjs-4.2.x -f Component.js - Opens the file in a remote branch other than the one that is currently checked out. git hub --hash b51abf6f38902 - Opens the commit hash. git hub --get-hash EXTJS-15755 - Opens the commit hash to which the local topic branch points. git hub --get-hash extjs5.1.0 - Opens the commit hash to which the tag points. git hub -f app.js --range 'L10-L20' - Opens the file with the specified range highlighted. =head1 AUTHOR Benjamin Toll <email@example.com>
Generate the file:
pod2man git-hub.pod > git-hub.1
I’ll list some of my favorite Git extensions, ones that I use every single day.
git-bootstrap - Open the files that make up a particular commit in Vim.
git-hub - Open any file, directory or commit on GitHub in regular view or blame view.
git-introduced - Find the commit(s) that introduced or removed a method or other search pattern.
git-ls - List the files that are staged and modified or that make up any given commit and optionally open in Vim for editing.

I don’t need no stinkin’ conclusion.
