require 'thor/actions/empty_directory'
class 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 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, 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
#
