h1. Boolean -- Additional Boolean-related core extensions

| *Author* | Tim Morgan |

| *Version* | 1.0 (Feb 15, 2011) |

| *License* | Released under the MIT license. |

h2. About

*Boolean* adds some helpful methods for working with Ruby's Boolean types,

@TrueClass@ and @FalseClass@ (the singleton classes whose only instances are

@true@ and @false@, respectively).

With *Boolean*, you get a @Boolean@ mixin so you can refer to @true@ and @false@

under a common class name:



  if variable.kind_of?(Boolean) then

    [ ... ]

  end



You can also type-cast Ruby objects into their Boolean values:



  "string".to_bool #=> true

  nil.to_bool #=> false



And you can parse various Ruby objects to Booleans:



  "yes".parse_bool #=> true

  "no".parse_bool #=> false

  1.parse_bool => true

  0.parse_bool => false



(@parse_bool@ is also aliased as @to_b@ to be consistent with the

@to_i@/@to_int@ naming paradigm.)

Lastly, inline with the @Integer()@ method, you have a @Boolean()@ method:



  Boolean("yes") #=> true

  Boolean("no") #=> false

  Boolean("maybe") #=> ArgumentError



h2. Installation and Usage

Just add the gem to your project's @Gemfile@:



gem 'boolean'



All the features shown in the previous section are now available in your project

code.

More information can be found in the class and method documentation.
