classnames

This is a port of JavaScript's classnames for Ruby. The API is basically the same except with Ruby's types.

Example usage

module ApplicationHelper
  include ClassNames

  def example
    str = classnames(
      'takes',
      ['any', 'kind'],
      { of: true, not_me: false },
      ->{ 'arguments' },
      nil, # and ignores ...
      false, # ... falsey values
    )
    # => "takes any kind of arguments"

    content_tag(:div, class: str) { 'So hot' }
  end
end

Installation

Add classnames to your Gemfile:

gem 'classnames', '~> 1.0.0'
