Truther

Easy convertion to boolean from truther and falsy values.

Installation

Add this line to your application's Gemfile:

gem 'truther'

And then execute:

$ bundle

Or install it yourself as:

$ gem install truther

Usage

Use #to_b on String, Integer, Float, nil, true or false.

'true'.to_b == true

'no'.to_b == false

Check Truther::TRUTHY_STRINGS and Truther::FALSY_STRINGS to find out how strings are mapped to boolean.

An unrecognized string will raise Truther::NeitherTrueNorFalseError unless a default value is provided. In which case the default value will be returned.

'maybe'.to_b(:i_dont_know) == :i_dont_know
