require_relative "empty_directory"

class Bundler::Thor
  module Actions
    # Copies recursively the files from source directory to root directory.
    # If any of the files finishes with .tt, it's considered to be a template
    # and is placed in the destination without the extension .tt. If any
    # empty directory is found, it's copied and all .empty_directory files are
    # ignored. If any file name is wrapped within % signs, the text within
    # the % signs will be executed as a method and replaced with the returned
    # value. Let's suppose a doc directory with the following files:
    #
    #   doc/
    #     components/.empty_directory
    #     README
    #     rdoc.rb.tt
    #     %app_name%.rb
    #
    # When invoked as:
    #
    #   directory "doc"
    #
    # It will create a doc directory in the destination with the following
    # files (assuming that the `app_name` method returns the value "blog"):
    #
    #   doc/
    #     components/
    #     README
    #     rdoc.rb
    #     blog.rb
    #
    # <b>Encoded path note:</b> Since Bundler::Thor internals use Object#respond_to? to check if it can
    # expand %something%, this `something` should be a public method in the class calling
    # #directory. If a method is private, Bundler::Thor stack raises PrivateMethodEncodedError.
    #
    # ==== Parameters
    # source<String>:: the relative path to the source root.
    # destination<String>:: the relative path to the destination root.
    # config<Hash>:: give :verbose => false to not log the status.
    #                If :recursive => false, does not look for paths recursively.
    #                If :mode => :preserve, preserve the file mode from the source.
    #                If :exclude_pattern => /regexp/, prevents copying files that match that regexp.
    #
    # ==== Examples
    #
    #   directory "doc"
    #   directory "doc", "docs", :recursive => false
    #
