How to write a module

Writing a module is fairly simple and allows you to implement your custom ways of generating filename combinations.

Below is a template for your modules:

#!/usr/bin/env python
#-*- coding: utf-8 -*-
“””
Module name: test
Coded by: Your name / nickname
Version: X.X
Description:
This module destroy the world.
“””
output = []
#Do some computations here
output = [“filename1.php”, “filename2.asp”, “filename3.jar”]

The variables url and filename are automatically imported from the core script, so you can call them in your module.

Once you finished to write your module, you have to save it in Modules/, and it will be automatically imported once the main script is started.

You can use the module shame as a template for your modules.
