module Early

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.

Public Class Methods

Applies a configuration, which means every variable is either defaulted or checked for existence.

# File lib/early.rb, line 85
def self.apply(config)
  config.variables.each(&:apply)
end

Accessing environment variables as constants. Raises Early::Error if missing.

# File lib/early.rb, line 91
def self.const_missing(name)
  RequiredVariable.new(name).apply
end

Env returns the early environment. This is either the value of RAILS_ENV, RACK_ENV (in that order) or the string 'development' if neither of the aforementioned environment variables are present.

# File lib/early.rb, line 79
def self.env
  ENV['RAILS_ENV'] || ENV['RACK_ENV'] || 'development'
end
