def destination_root=(root)
  @destination_stack ||= []
  @destination_stack[0] = File.expand_path(root || "")
end

#directory(source, *args, &block) ⇒ Object

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

Encoded path note: 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
