Subversion PS1 prompt functions for bash

subversion-prompt.sh

#
# If you want to see svn modifications:
# export SVN_SHOWDIRTYSTATE=1 
#
# Put this in your PS1 like this:
# PS1='\u@\h:\W\[\033[01;33m\]$(__git_svn_ps1)\[\033[00m\]$ '


# Git/Subversion prompt function
__git_svn_ps1() {
    local s=
    if [[ -d ".svn" ]] ; then
        local r=`__svn_rev`
        local b=`__svn_branch`
        s=" [$b:$r]"
    elif [[ -d .git ]] ; then
        s=`__git_ps1`
    fi
    echo -n "$s"
}

# Outputs the current trunk, branch, or tag
__svn_branch() {
    local url=
    if [[ -d .svn ]]; then
        url=`svn info | awk '/URL:/ {print $2}'`
        if [[ $url =~ trunk ]]; then
            echo trunk
        elif [[ $url =~ /branches/ ]]; then
            echo $url | sed -e 's#^.*/\(branches/.*\)/.*$#\1#'
        elif [[ $url =~ /tags/ ]]; then
            echo $url | sed -e 's#^.*/\(tags/.*\)/.*$#\1#'
        fi
    fi
}

# Outputs the current revision
__svn_rev() {
    local r=$(svn info | awk '/Revision:/ {print $2}')

    if [ ! -z $SVN_SHOWDIRTYSTATE ]; then
        local svnst flag
        svnst=$(svn status | grep '^\s*[?ACDMR?!]')
        [ -z "$svnst" ] && flag=*
        r=$r$flag
    fi
    echo $r
}

I did the regex on L30 a little different; sed apparently can't do non-greedy regexes so I used perl instead:

elif [[ $url =~ /branches/ ]]; then
    echo $url | perl -pe 's|^.*/branches/(.*?)/.*$|\1|'

This made it so only the branch name was displayed, not the branch and remaining path to CWD.

I also added @pestophagous __svn_info_str method. I'm on a pretty old version of SVN though (1.8.9)

A key feature of the changes introduced in Subversion 1.7 is the centralization of working copy metadata storage into a single location. Instead of a .svn directory in every directory in the working copy, Subversion 1.7 working copies have just one .svn directory—in the root of the working copy.
