JsonToEnv

JsonToEnv loads JSON into your process environment. If you call JsonToEnv multiple times, earlier invocations take priority because anything already in ENV will not be overwritten by JsonToEnv.

Given a JSON structure like this one:

{
  "one": "two",
  "three": {
    "four": 5
  }
}

Before you need to access environment variables:

JsonToEnv.load(json)

Now you can access your configuration through ENV:

ENV['THREE_FOUR'] == 5
