matchrb

matchrb (pronounced 'matcherby') provides a simple but powerful way to do pattern matching in Ruby.

Installation

Add this line to your application's Gemfile:

gem 'matchrb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install matchrb

Usage

matchrb implements two methods, #match and #otherwise. You can use them globaly like so:

require 'matchrb/global'

object = 100
match object,
  String    => "object is a string",
  Integer   => "object is an integer",
  otherwise => "object is...just an object"

or, to avoid name clashes, use them individually:

require 'matchrb'

object = 100
Matchrb.match object,
  String            => "object is a string",
  Integer           => "object is an integer",
  Matchrb.otherwise => "object is...just an object"

That's it!
