Because Git is awesome, but it can be FABULOUS!
fabgit uses the amazing whatthejeff/fab library to make your git output look fabulous.
You can use it in the same way you use composer - save the phar file it to your /usr/bin as 'fabgit' and it shall be available system-wide as a command, or use as php fabgit.phar [your git commands]
You only need the fabgit.phar file.
curl -O http://erikaheidi.github.io/fabgit/fabgit.phar
chmod +x fabgit.phar
sudo cp fabgit.phar /usr/sbin/fabgit
And it shall be available globally.
fabgit
You can contribute or make your own customizations, just clone the repo and have fun! :)
Head to the src/fab.php and build your .phar file using the build/build.php.
