Ruby: pretty directory recursion :P

gistfile1.rb

# EDIT: this can actually be done more simply like this:

Dir.foreach("path/to/directory/**/*") do |item|
  next if File.directory? item
  # Do whatever with item now
end

# Define this somewhere
def each_file(dir = ".", &block)
  Dir.foreach(dir) do |item|
    next if item == '.' or item == '..'
    path = File.join dir, item
    unless File.directory? path
      yield path
    else
      each_file path, &block
    end
  end
end

# Then, whenever you want to recurse through all files and subdirectories in a directory...
each_file "path/to/directory" do |filename|
  puts filename
end

# Or, if we just want to go through the current directory
each_file do |filename|
  puts filename
end

# If we were to monkey patch the built-in Dir class like this... 
class Dir
  def self.each_r(dir = ".", &block)
      foreach(dir) do |item|
      next if item == '.' or item == '..'
      path = File.join dir, item
      unless File.directory? path
        yield path
      else
        each_r path, &block
      end
    end
  end
end

# ... then we could just do this:
Dir.each_r "path/to/dir" do |filename|
  puts filename
end
