Displaying SVN Info On Your PowerShell Prompt

Came across this post Displaying GIT Branch on your PowerShell prompt and built it for subversion. Add this to your $PROFILE.

function prompt {
 $host.ui.rawui.WindowTitle = $(get-location)
 if(Test-Path .svn) {
  switch -regex (svn st) {
   "^\?" {$other+=1}
   "^A" {$added+=1}
   "^M" {$modified+=1}
   default {}
  }
   $prompt_string = "SVN o:$other a:$added m:$modified >"
  } else {
   $prompt_string = "PS >"
  }
  
  Write-Host ($prompt_string) -nonewline -foregroundcolor yellow
  
  return " "
}

For a directory that is an svn working copy.

• o:4 – 4 files not under version control
• a:1 – 1 item scheduled for addition
• m:1 – 1 item has been modified

Issuing svn add or check in commands causes the prompt to be refreshed.
