Molar

Molar dynamically defines attribute hash getters and setters for your classes.

Work in progress

Installation

Add this line to your application's Gemfile:

gem 'molar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install molar

Usage

class Jedi
  include Molar

  def initialize(attributes = {})
    @attributes = attributes
  end
end

jedi = Jedi.new(name: 'Luke Skywalker', master: 'Yoda')

jedi.name
# => 'Luke Skywalker'

jedi.master
# => 'Yoda'

jedi.name = 'Anakin'
jedi.name
# => 'Anakin'

Molar defines accessors and setters on the fly so as not to incur the :method_missing penalty on each access. Currently, only lookups in the @attributes instance variable are supported.

Currently, mutation coverage is ~77%, but I haven't yet had a chance to determine how meaningful that is, as this gem uses a couple of items listed under the limitations section for mutant (which is a great tool, by the way).

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
