Controlling Subversion with Ruby and the command line

I love the syntax and ease of developing in Ruby. Unfortunately, there isn't much Ruby work. Therefore, I use Ruby as often as I can for simple tasks I'd like to automate.

Subversion's command line client does everything you need, but not always as easily as possible. For example, I'd like a command that adds all the unknown files returned from a `svn status`. Yes, you can `svn add .`, but that seems to try to add everything and produces warnings.

I think you see where I'm going with this.

Where should we start? With tests obviously.

require 'svndir'
require 'test/unit'

class SvnTestCase < Test::Unit::TestCase
 def testMassAdd()
  tempFile = createTempFile()
  assert_equal("?",tempFileStatus(tempFile))

  svnDir = SvnDir.new()
  svnDir.add();

  assert_equal("A",tempFileStatus(tempFile))
  removeTempFile(tempFile)
 end
 
 def createTempFile(fileName = "tempFile.temp.temp")
  flunk("#{fileName} file already exists") if File.exist?(fileName)
  `echo fileName > #{fileName}`
  assert(File.exist?(fileName))
  fileName
 end
 
 def removeTempFile(fileName)
  `svn revert #{fileName}` if tempFileStatus(fileName) == "A"
  File.delete(fileName) if File.exist?(fileName)
  assert(!File.exist?(fileName))
 end
 
 def tempFileStatus(tempFile)
  `svn status`.to_s =~ /(\?|A)\s+#{tempFile}/
  $1
 end
end

Now that I know what I'm looking for from a SvnDir class I can implement it:

class SvnDir
 def add()
  svnStatus().each { |line| addFile(line) if unknown?(line) }
 end
 
 def svnStatus()
  `svn status`.to_s.split(/\n/)
 end
 
 def unknown?(statusLine)
  statusLine =~ /^\?/
 end
 
 def addFile(statusLine)
  statusLine =~ /^\?\s+(.*)$/
  `svn add #{$1}`
 end
end

I'm still learning Ruby, so please comment with better ways to do this.

I asked Subversion guru Mike Mason if there was an easier way, and he suggested TortoiseSVN. It's true, adding is easier in Tortoise, but I'm just too much of a control freak to give up my command line.
