Useful Ruby Scripts

Absolute vs. Relative Path

Sometimes, there is a need to use the relative or absolute path to load a file. For example, if you have a file located in the a sub-directory to require the file, you can use the following scripts:

• Method 1:

require "#{File.dirname(__FILE__)}/resources/filename"

or

• Method 2:

require "#{Dir.pwd}/resources/filename"

The first method uses the relative path, meaning '.', while the second method uses the absolute path.
