      1 # Git branch in prompt
      2 
      3  While creating set of [bash_completion rules](https://bugs.freedesktop.org/show_bug.cgi?id=34973) for mc-tool, I read some other rule files to see how things are done. I happened to spot some useful functions from git's completion, mainly __git_ps1, which prints the name of the current branch.
      4 
      5  Having the name of the current branch can save some mistakes every now and then, and with environment variable GIT_PS1_SHOWDIRTYSTATE you can even make it show if there are non-staged and/or non-committed changes in your tree.
      6 
      7  This is how I used it:
      8 
      9 `PS1='\u@\h \w$(GIT_PS1_SHOWDIRTYSTATE=1 __git_ps1)\$ '`
     10 
     11 By default the output of __git_ps1 is " (name-of-branch)", or "" if current directory does not belong to a git tree. The format string can be given on command line, like " (%s)".
     12 
     13  The current version seems to have a small glitch that causes it to print give (unknown) for home directory, if you use git global settings.
