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.
