Re: StGit-enabled bash-prompt

Hi,

I added the following snippet to my .bashrc to help me keep track of what patch I'm working on. I got annoyed at typing stg top/stg series all the time.

This changes the bash prompt to include the current git branch and the top stgit patch to the prompt.

Of course you will read and understand this code. I don't know how good an idea it is to use the DEBUG trap this way.

NO WARRANTY (as always)

-- robin

if [ "$PS1" ]; then
    function stgtag
    {
        br=$(stg branch 2>/dev/null)
        top=$(stg top 2>/dev/null)
        if [[ -n "$br$top" ]];then
            echo " [$top@$br] "
        fi
    }
    trap 'PS1="\u@\h$(stgtag)\w]\$ "' DEBUG

I set my prompt without using it, with something approximating this being defined in my .bash_profile. I think the use of ' instead of " causes evaluation of __prompt_githead be delayed until the prompt is displayed.

  PS1='$(__prompt_githead) '$PS1

  __prompt_githead() {
  PS_GIT=$(git-symbolic-ref HEAD 2>/dev/null) || exit
  echo -n " $(basename $PS_GIT)" 
  }

Ahh, ofcourse. Thanks.
