[OT] git branches and command prompts

[OT] git branches and command prompts

[Jason]

All,

if you're like me, you play with a lot of open source code.  A lot of it is now in git repositories.  I frequently forget which branch I'm on in each project, particularly with Android/Cyanogen.  Here's a hack I figured out that helps me out, place it in ~/.bashrc :

### begin ####
PROMPT_COMMAND="echo -n \${PWD};
         if git branch >/dev/null 2>&1; then 
            echo -n \" (\$(git branch | grep ^* | cut -d ' ' -f 2-))\"
         fi"
PS1="\n[\[\033[01;34m\]\u\[\033[00m\]@\h] $ "
export PROMPT_COMMAND PS1
### end ######

Here's the result:

/home/jason
[jason@phantom] $ cd src/foss/git.git
/home/jason/src/foss/git.git (master)
[jason@phantom] $ git checkout git_shell_dir_opt 
Switched to branch 'git_shell_dir_opt'
/home/jason/src/foss/git.git (git_shell_dir_opt)
[jason@phantom] $

Obviously you can tweak it to just one line, or a simpler PS1, or whatever.  Thought it might help some folks.

Sorry, TB mangled the formatting.  Hopefully quoting helps. :-(

Since we are sharing, mine is at
<http://github.com/mina86/dot-files/blob/master/bashrc>. Also, from what
I know, bash-completion package has some funky command meant to be used
in prompt.

wow.  That rocks.  There are so many neat tricks in there it's not even funny.

Thanks for sharing.
