This gem is for detecting environment variables referred from ruby.
In the case which multiple applications share the same server and so many environment variables are exported in it, it may difficult to grasp which environment variable is referred from which application.
ENV.[] and ENV.fetch will be caught and logged by this gem. It helps you to grasp the above thing.
I wouldn't recommend using this gem in production. You would achieve the purpose even in a staging or another environment.
Add this line to your application's Gemfile:
gem 'env_detective'And then execute:
$ bundle
Or install it yourself as:
$ gem install env_detective
This will override ENV and when ENV is referred, that will be logged to STDOUT.
require 'env_detective'
ENV = EnvDetective.extend(ENV)If you want to use another logger or change output file, you can set logger like below.
require "env_detective"
require "logger"
EnvDetective.configure do |config|
config.logger = Logger.new(File.join(__dir__, 'log/env_detective.log'))
end
ENV = EnvDetective.extend(ENV)Bug reports and pull requests are welcome on GitHub at https://github.com/grezar/env_detective.
