Kernel#Boolean

Returns a boolean based on the given argument.

Add this line to your application's Gemfile:

gem "kernel-boolean"

And then execute:

bundle install

Or install it yourself as:

gem install kernel-boolean

If the argument is true, returns true. If the argument is false, returns false.

In all other cases, returns an error.

require "kernel/boolean"

Boolean(false)  # => false
Boolean(true)   # => true
Boolean(nil)    # => TypeError: can't convert nil into boolean
Boolean("true") # => ArgumentError: invalid value for Boolean(): "true"

The #Boolean method could be used similarly to the methods already present in the Kernel module:

• #Array
• #Complex
• #Float
• #Hash
• #Integer
• #Rational
• #String

The Kernel module is included in the Object class, so by loading this library, the #Boolean method will be available in every Ruby object.

Kernel#Boolean uses Semantic Versioning 2.0.0

• kernel-symbol: Returns a Symbol based on the given argument.
