Blankable

Implementation of blank? in Elixir. Aims to work in a practically identical fashion to ActiveSupport's #blank? method.

Installation

Add blankable to your list of dependencies in mix.exs:

def deps do
  [{:blankable, "~> 0.0.1"}]
end

Usage

iex> Blankable.blank?(nil)
true
iex> Blankable.blank?("")
true
iex> Blankable.blank?([])
true
iex> Blankable.blank?("Hello")
false
