A Ruby script for TextMate to cleanup your project's PHP according to WordPress PHP Coding Guidelines.

gistfile1.rb

#!/usr/bin/env ruby

# Author: Rheinard Korf

# Usage:
# Needs to be added to a TextMate bundle as a new 'Command'
# Set command's input to 'None' and output to 'Show in Tool Tip'

# What it does:
# - Adds whitespace inside parentheses.
# - Adds whitespace after commas. Note: If you're using commas for comparing strings, just double check those.
# - Adds whitespace around =, ==, ===, =>
# - Adds whitespace before ! operator
# - Removes all trailing spaces
# - Replaces <? with <?php

# Todo:
# - Boolean operators (&&, ||)
# - Mathematical operators (+,-,*,%)
# - Compound assignment operators (+=, -=, etc)
# - Bitwise operator

path = ENV['TM_PROJECT_DIRECTORY'] ? ENV['TM_PROJECT_DIRECTORY'] : '.'

file_names = Dir.glob( "#{path}/**/*" )

count = 0

file_names.each do |file_name|
  
  if ( ! File.directory?(file_name) ) then

    text = File.read(file_name)

    allowed_extensions = [ '.php' ]

    if allowed_extensions.include? File.extname(file_name) then

      # Parentheses
      textx = text.gsub(/(\S)(?=\))/, '\1 ')
      textx = textx.gsub(/\((?=\S)/, '( ')
      textx = textx.gsub('( )', '()')

      # Commas
      textx = textx.gsub(/,(?=\S)/, ', \1')

      # = operators
      textx = textx.gsub(/=(?=[^\r\n\t\f=\>\W\ ])/, '= ')
      textx = textx.gsub(/([^\r\n\t\f=\W\ ])(?=\=)/, '\1 ')

      # ! not operator
      textx = textx.gsub(/\!(?=[^\r\n\t\f=\ ])/, '! ')

      # Remove trailing spaces
      textx = textx.gsub(/[ \t]+$/, '')

      # Remove PHP short tags
      textx = textx.gsub(/<\?(?=\W)/, '<?php')

      if text != textx then
        File.open( file_name, "w") { |file| file.puts textx }
        count += 1
        puts "#{file_name} updated."
      end
            
    end
        
  end

end

puts "Project cleaned. #{count} files updated."

Still a work in progress, but already pretty useful I believe.

Note, limited it to .php, but should work ok for .js. Haven't tested. But please make sure you don't run it against all files. At least keep .php in there.
