Module: Early

Defined in:
lib/early.rb,
lib/early/travis.rb

Overview

Early checks for environment variables availability, so you don’t have to.

Hook it early in your program and work with ‘ENV` like you normally would. This time, however, the errors would be thrown early and not when a critical piece of code is hit, which may happen late in the program runtime an be easy to miss.
