Overview

In ruby, require_relative attempts to load the library relative to the directory of the currently executing file. Crystal does not have require_relative, but it has the same behavior in the form of require ‘./foo’

Examples:

# bad
require_relative 'foo'
require_relative './bar'
require_relative '../baz'
require_relative '/qux'

# good
require './foo'
require './bar'
require '../baz'
require '/qux'
