SmartEnv

gem install smart_env

require 'smart_env'

Purpose

Attach hooks to your ENV vars and wrap them in Proxy Objects.

Example with built-in URI Proxy

ENV.use(SmartEnv::UriProxy)

ENV['SERVICE'] = 'http://username:password@example.com:3000/"

ENV['SERVICE']             #=> 'http://username:password@example.com:3000/"
ENV['SERVICE'].base_uri    #=> 'http://example.com:3000"
ENV['SERVICE'].user        #=> 'username'
ENV['SERVICE'].password    #=> 'password'
ENV['SERVICE'].host        #=> 'example.com'
ENV['SERVICE'].scheme      #=> 'http'
ENV['SERVICE'].port        #=> 3000

Add your own Proxies

With a block

class TestProxy
  def initialize(key, value)
  end
end

ENV.use(TestProxy).when { |key, value| key == 'FOO' }

ENV['FOO'] = 'bar'
ENV['FOO'].class           #=> TestProxy

Or by implementing ::when

class TestProxy
  def initialize(key, value)
  end

  def self.when(key, value)
    key == 'FOO'
  end
end
ENV.use(TestProxy)

ENV['FOO'] = 'bar'
ENV['FOO'].class           #=> TestProxy
