Show Git and Subversion Branch in Your Bash Prompt 0.2

Thu 2010-09-02 ( In En pr )

When you include this in your ~/.bash_login file:

# Show current git branch or SVN subfolder in prompt.
      GREEN="\[\033[0;32m\]"
LIGHT_GREEN="\[\033[1;32m\]"
       GRAY="\[\033[1;30m\]"
 LIGHT_BLUE="\[\033[1;34m\]"
 LIGHT_GRAY="\[\033[0;37m\]"
  COLOR_OFF="\[\e[0m\]"
function prompt_func() {
  branch_pattern="\* ([^$IFS]*)"
  PS1="$LIGHT_GRAY`date +%H:%M:%S`$COLOR_OFF $LIGHT_GREEN\w$COLOR_OFF"
  if [[ -d "./.git" && "$(git branch --no-color 2> /dev/null)" =~ $branch_pattern ]]; then
    branch="${BASH_REMATCH[1]}"
    PS1+=":$LIGHT_BLUE$branch$COLOR_OFF"
  elif [[ -d "./.svn" ]]; then
    path_pattern="URL: ([^$IFS]*).*Repository Root: ([^$IFS]*).*Revision: ([0-9]*)"
    if [[ "$(svn info 2> /dev/null)" =~ ${path_pattern} ]]; then
      branch=`/usr/bin/ruby -e 'print ARGV[0][ARGV[1].size + 1..-1] || "/"' ${BASH_REMATCH[1]} ${BASH_REMATCH[2]}`
      revision="${BASH_REMATCH[3]}"
      PS1+=":$LIGHT_BLUE$branch$GRAY@$revision$COLOR_OFF"
    fi
  fi
  PS1+=" "
}
PROMPT_COMMAND=prompt_func

…it should show you, depending on what kind of folder you’re in, the current git or svn branch:

~ cd ruby/coderay
~/ruby/coderay:trunk@644 cd ../coderay-0.9
~/ruby/coderay-0.9:branches/0.9@641 cd ~/studies/ikiwiki/
~/studies/ikiwiki:master

It is quite fast, but needs Ruby (any idea for a bash-only version?)

Update: Fixed a few things.
Update 2: Cleanup, SVN revison number.

Hey murphy :),

at the bottom of http://rbjl.net/21-rubybuntu-3-be-one-with-your-command-line is my version for a git prompt with ⚡, using only bash.

Cool!  I think you can get rid of the '-d "./.git" &&', though -- otherwise you only see your branch in the git root directory.

Giles: That's true, but it speeds up the prompt function when I'm *not* in a git directory. I also rarely leave the root directory.

Replace the Ruby line with this:

branch=`expr ${BASH_REMATCH[1]:\`expr match ${BASH_REMATCH[1]} ${BASH_REMATCH[2]}\`+1}

Greg Gaughan @ 14:55 on Wednesday, 2010-09-22

or even better:

branch=${BASH_REMATCH[1]##`expr ${BASH_REMATCH[2]}`}
