dirty little script I used to fix escaped character sequences in a yaml file

unescape.rb

lines = File.read(ARGV.first).split("\n")

File.open(ARGV.last, 'w') do |out|
  lines.each do |line|
    if line =~ /:/
      key, value = line.split(/:\s*/, 2)
      value = eval(value) if value =~ /^"/
      if value =~ /\{|"|:/
        value.gsub!(/"/, "\\\"")
        value = "\"#{value}\""
      end
      out.write("#{key}: #{value}\n")
    else
      out.write("#{line}\n")
    end
  end
end
