Stein

A micro gem that allows Main modes be written in separate files and magically stitched together.

This may become convenient whem your utility becomes monstrously large:

8-foot-tall (2.4 m), hideously ugly creation, with translucent yellowish skin pulled so taut over the body that it "barely disguised the workings of the vessels and muscles underneath"; watery, glowing eyes, flowing black hair, black lips, and prominent white teeth.

Add this line to your application's Gemfile:

gem 'stein'

And then execute:

$ bundle

Or install it yourself as:

$ gem install stein

Start with the main "body" of the utility:

bin/frankenstein

#!/usr/bin/env ruby
require 'main'
require 'stein'

$LIB_DIR = File.dirname(File.dirname __FILE__) + '/lib'

Main {
  description "Show how to build a monster utility from a bunch of modes"
  def run ; help! ; end
  Stein.extend self, $LIB_DIR + '/modes'
}

Then place your modes in lib/modes/:

lib/modes/feed.rb

Stein.mode 'feed' do
  description "Go to the village and steal some food"
  def run
    go(village)
    food = steal
    eat(food)
  end
end

That's it.

Stein.mode mode_name, &block: can be used in the top level of a mode-file (a ruby file in modes directory). It delegates itself to Main DSL's mode, eventually.

Stein.extend main_module, modes_directory: loads all modes definitions from the directory.
