"include" vs "require"

[NewOne]

Hy ! It may look like a newbie question - that is it
But... can somebody explain what is the difference between "include" and "require" statement? Maybe with a simple example to fix this once for ever in my mind.

Thank you!

What's the difference between "include" and "require" in Ruby?

Answer:

The include and require methods do very different things.

The require method does what include does in most other programming languages: run another file. It also tracks what you've required in the past and won't require the same file twice. To run another file without this added functionality, you can use the load method.

The include method takes all the methods from another module and includes them into the current module. This is a language-level thing as opposed to a file-level thing as with require. The include method is the primary way to "extend" classes with other modules (usually referred to as mix-ins). For example, if your class defines the method "each", you can include the mixin module Enumerable and it can act as a collection.
