Agnoster Adaption

The SVN plugin of the oh-my-zsh ZSH distribution is not working with the agnoster theme, because it's simple not used in the prompt of the theme. Here two adaption of the theme file (themes/agnoster.zsh-theme) are listed, which are showing a nice prompt when you are in a SVN working directory.

Using the SVN plugin (with dirty symbol)

prompt_svn() {
  local rev branch
  if in_svn; then
    rev=$(svn_get_rev_nr)
    branch=$(svn_get_branch_name)
    prompt_segment yellow black
    echo -n "$rev@$branch"
    if [ `svn_dirty_choose_pwd 1 0` -eq 1 ]; then
      prompt_segment red black
      echo -n "±"
    fi
  fi
}

Not using the SVN plugin (faster, without dirty symbol, maybe not working in all circumstances)

upsearch () {
  slashes=${PWD//[^\/]/}
  directory="$PWD"
  for (( n=${#slashes}; n>0; --n ))
  do
    test -e "$directory/$1" && return 0
    directory="$directory/.."
  done
  return 1
}

prompt_svn() {
  local svn_info rev branch
  #if [ -d ".svn" ]; then
  upsearch .svn
  if [ $? -eq 0 ]; then
    svn_info="$(svn info 2> /dev/null)";
    if [ $? -eq 0 ]; then
      rev=$(echo $svn_info | sed -n 's/Revision:\ //p')
      branch=$(echo $svn_info | \
        awk -F/ \
        '/^URL:/ { \
          for (i=0; i<=NF; i++) { \
            if ($i == "branches" || $i == "tags" ) { \
              print $(i+1); \
              break;\
            }; \
            if ($i == "trunk") { print $i; break; } \
          } \
        }'
      )
      prompt_segment yellow black
      echo -n "$rev@$branch"
    fi
  fi
}

For that adoption I reused code of the SVN plugin, as well as code of an answer at unix.stackexchange.com.

To get it work you have to include one of the above code snippets into your agnoster theme file (themes/agnoster.zsh-theme) and adapt the build_prompt function to include the call of the prompt_svn function. Like:

build_prompt() {
  RETVAL=$?
  prompt_status
  prompt_virtualenv
  prompt_context
  prompt_dir
  prompt_git
  prompt_hg
  prompt_svn
  prompt_end
}
