annoys me to no end that to_bool isnt built in to ruby and that to_i isnt built into boolean classes. fixed.

bool_tools.rb

class TrueClass
  def to_i
    1
  end

  def to_bool
    self
  end
end

class FalseClass
  def to_i
    0
  end

  def to_bool
    self
  end
end

class Fixnum
  def to_bool
    self == 0 ? false : true
  end
end

class String
  def to_bool
    self == "0" ? false : true
  end
end

class NilClass
  def to_bool
    false
  end
end
