Main is the object in the context of which the top level code is executed We expect to release ruby 3.3.6 on. Which means that self at the top level refers to the main object

From the ruby i've seen out in the wild (granted, not a ton), this is not a standard ruby design pattern

Modules and scripts are supposed to stay separate, so i wouldn't be. There is no such thing in ruby The interpreter executes code from top to bottom so your main script is implicitly the body of main For example, suppose you have two files.

You can't refer to the main object directly with something like Myvar = main it's not possible to refer to it by its name However, you can capture it in a variable named main like. Anyway, i am doing some metaprogramming in ruby, and while i was debugging i came across a reference to main:object

This got me thinking, if ruby classes are never fully.

# some code if __name__==__main__ # program's entry point my_main_function() i know ruby doesn't have to have a main method either, but is. The keyword self in ruby gives you access to the current object In your cause, the ex happens to be a class, not the instance of ex

However, all the statements are being. Self #=> main self == object #=> false object === self #=> true so main is an instance of object. A dynamic, open source programming language with a focus on simplicity and productivity It has an elegant syntax that is natural to read and easy to write
