Consider the following module.
Module function ruby example.
Using the require method.
Examples to implement of ruby modules.
These functions may be called with the module as a receiver and also become available as instance methods to classes that mix in the module.
They are things that hold methods just like classes do.
Below are the examples of ruby modules.
This is an example where we are creating a module and inside this module we are defining a few methods and a constant and then we are directly accessing these methods and constants with the name of the modules.
If used with no arguments subsequently defined methods become module.
The function takes number1 and number2 whose modulo is returned.
However modules can not be instantiated.
Second a ruby include does not simply copy the module s instance methods into the class.
And modules unlike classes therefore do not have a.
So this behavior isn t that different from the instance method behavior we saw in the first example.
Inside of a class or module definition.
In ruby a module can be used as logical entity.
The require method takes the name of the file to require as a string as a single argument this can either be a path to the file such as lib some library rb or a shortened name such as some library if the argument is a path and complete filename the require method will look there for the file.
The modulo function in ruby returns the modulo value of a number by another number.
Module functions are copies of the original and so may be changed independently.
It now makes sense to introduce another language feature in ruby.
If that module is in a separate file you must use require to drag that file in before using include.
I e it is not possible to create objects from a module.
It groups methods at a module level without using the mixin facility for example the base64 module i highly recommend you to read the source.
The ruby include statement simply makes a reference to a named module.
You can embed a module in a class.
We can explain the below example in the.
The instance method versions are made private.
The function returns the modulo value of a number by another number.
Remember classes and modules are treated as objects in ruby.
One feature of ruby that makes it such a good fit for frameworks like rails is that you can execute arbitrary code inside class and module.
