This is actually a question about this question: Adding a directory to $LOAD_PATH (Ruby)
What happens when you add a directory to the $LOAD_PATH? Is it like adding a script file to the execution context as in JavaScript? (You can access global methods/objects in another files) If not, how do I call the methods of other ruby files in the current directory?
When you add the /Users/you/scripts/ruby
directory to the load path, you can use:
require 'example'
instead of:
require '/Users/you/scripts/ruby/example.rb'
Think of the $LOAD_PATH
as to being similar to the PATH
variable on a operating system. If certain directories are in the LOAD_PATH, you can just write require "some_module"
.
It's also the reason for being able to require
files from the current directory.
By default, the LOAD_PATH no longer includes the current directory .
having been removed in Ruby 1.9.2.
