Overview
This class aims at easing the creation of custom binary for your needs. For example, you can add new options or change the existing ones. The parsing is handled by Ruby's OptionParser. For instance:
class Custom::CLI < Greenmat::CLI
def self.
super.tap do |opts|
opts.on("--rainbow") do
@@options[:rainbow] = true
end
end
end
def self.render_object
@@options[:rainbow] ? RainbowRender : super
end
end
