Caty

• http://github.com/karottenreibe/caty

Description

Caty is a command line parser that operates on the same principle as Yehuda Katz's Thor (http://github.com/wycats/thor/tree/master). It maps the arguments given by the user to instance methods of a class and can automatically parse options.

Features

• Define tasks that get mapped directly to instance methods of a class
• Define global (e.g. --beer) and task-specific (e.g. -rootbeer) options
• Have String, Integer and Boolean options
• Have options with default values

Synopsis

require 'rubygems'
require 'caty'

class Kitty < Caty

    global_options do
        boolean :quiet, false
    end

    desc('WHAT', cut("
        Kitty's hungry!
        You can specify any amount of food to feed the kitty.
    "))

    task_options :amount => 1

    def eat( something )
        unless global_options.quiet
            puts "I'm eating #{something}. I'm #{task_options.speed}!"
        end
    end

    help_task

end

Kitty.start!


#
# now you can do:
# $> kitty eat fish -amount=5 --quiet
# $> kitty help
# ...
