Dynamically extend options on a Thor::Command

ThorExtend

ThorExtend adds options to already defined Thor commands. Normally, you define options like this:

require 'thor'
class MyCLI < Thor
  option :arg1
  option :arg2
  def action
    #...
  end
end

This is only works if you know the options upfront but not if you need to define them at runtime dynamically. With ThorExtend you can add those when the cli class is already loaded:

extender = ThorExtend.new(MyCLI)
extender.command("action").add(:arg3, {})

Here you add arg3 to the action command. The hash which is passed to add contains options you would normally pass additionally, e.g. a type. Example:

option :yesno, :type => :boolean
def action
end

Installation

Add this line to your application's Gemfile:

gem 'ThorExtend'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ThorExtend
