Git auto complete

11-01-2011

Git auto complete is a convenient feature.

This feature is based on git-completion file comes with git.

On OS X, if you install git via homebrew, you can find git source directory using:

locate git | grep Cellar

Locate the git-completion file.

In my case, it is `/usr/local/Cellar/git/1.7.5/etc/bash_completion.d/git-completion.bash

Open this file and you will find this explanation:

The contained completion routines provide support for completing:

• local and remote branch names
• local and remote tag names
• .git/remotes file names
• git ‘subcommands’
• tree paths within ‘ref:path/to/file’ expressions
• common –long-options

And the steps to enable this

• Copy this file to somewhere (e.g. ~/.git-completion.sh).
• Add the following line source ~/.git-completion.sh to your .bashrc
• Changing PS1 to show current branch PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '

If you want some color in git prompt

PS1='\[\033[32m\]\u@\h\[\033[00m\]:\[\033[34m\]\w\[\033[31m\]$(__git_ps1)\[\033[00m\]\$ '

If you want the prompt to show git-ps1 state GIT_PS1_SHOWDIRTYSTATE=true
