BooleanClass

Description

Performs type conversion from anything to true:TrueClass / false:FalseClass

Boolean(0.0)         #=> true
FalseClass < Boolean #=> true

Anti-Features

Similar to boolean gem but:

Without parse_bool()
Without raising exceptions
Without to_bool() to_b() methods
Does not pollute Object or Kernel; polite monkey patching with include BooleanClass::Conversion

Installation

$ gem install boolean_class or add to your Gemfile this line: gem 'boolean_class' then run bundle install

Usage

Just require 'boolean_class' and then use it as:

As a conversion method Boolean()

require 'boolean_class'

# Example true values
Boolean(true)  #=> true
Boolean(999)   #=> true
Boolean(0)     #=> true

# Example false values
Boolean(false) #=> false
Boolean(nil)   #=> false

As data type checking / validation

require 'boolean_class'

# Instance type checking
true.is_a?(Boolean)   #=> true
false.is_a?(Boolean)  #=> true
0.is_a?(Boolean)      #=> false
nil.is_a?(Boolean)    #=> false
(0==1).is_a?(Boolean) #=> true

# Class type checking
Object < Boolean      #=> nil (false)
NilClass < Boolean    #=> nil (false)
Class < Boolean       #=> nil (false)
TrueClass < Boolean   #=> true
FalseClass < Boolean  #=> true
