Attributor::Flatpack

This library provides an Attributor type, Attributor::Flatpack::Config, for loading messy data from sources like the ENV hash. Based on the Go flatpack library.

Add this line to your application's Gemfile:

gem 'attributor-flatpack'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attributor-flatpack

Define your config type, similarly to an Attributor::Hash:

class SampleConfig < Attributor::Flatpack::Config
  keys do
    key :rack_env, String
    key :database do
      key :host, String
      key :username, String
      key :password, String
    end
    key :web do
      key :maxconn, Integer
      key :workers, Integer
    end
  end
end

Create an instance of it from a given input hash:

config = SimpleConfig.load(ENV)

And then simply use the attributes defined to retrieve values:

config.rack_env
# => development
config.database.host
# => localhost:9160

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
