Overview

File: ./lib/skn_utils/env_string_handler.rb

Wrapping a string in this class gives you a prettier way to test for equality. The value returned by Rails.env is wrapped in a StringInquirer object so instead of calling this:

Rails.env == 'production'
SknSettings.env == 'production'

you can call this:

Rails.env.production?
SknSettings.env.productcion?

Create a EnvStringHandler to support: SknSettings.env.development? Yes, its YAML trick in config/settings.yml

 ...
 env: !ruby/string:SknUtils::EnvStringHandler <%= ENV['RACK_ENV'] %>
root: !ruby/string:SknUtils::EnvStringHandler <%= Dir.pwd %>
 ...
