reindent_files.rb

class String
  def reindent(by = 2)
    self.gsub("\t", " " * by)
  end
end

absolute_path = "/home/guimello/NetBeansProjects/ihouse"

dirs = ["#{absolute_path}/app/**", "#{absolute_path}/config/",
        "#{absolute_path}/config/environments",
        "#{absolute_path}/db/migrate", "#{absolute_path}/lib",
        "#{absolute_path}/public/**"]

dirs.each do |dir|
  Dir.glob("#{dir}/*.{rb,erb,js,css}") do |match|
    next if match.split("/").last == "boot.rb"
    
    lines = []
    File.open(match, "r") do |file|
      while line = file.gets
        lines << line.reindent
      end
    end
    
    File.open(match, "w") do |file|
      lines.each {|l| file.write l}
    end
  end
