Module:Sandbox/Aidan9382/CodeAnalysis/doc

This function provides basic analysis of module code, pointing out any unused variables or unexpected globals.

The code of this is mostly lifted from https://github.com/9382/Dump/tree/main/LuaObfuscator, which in turn lifts a lot of code from https://github.com/stravant/LuaMinify.

Usage

This module can be required and used from the Debug console, like the following: require("Module:Sandbox/Aidan9382/CodeAnalysis")() (The module entry point can be accessed directly without calling it via .run). The module will then log any behaviour it notices. The function can be provided an argument to specify a target page other than the current page. Valid inputs are the name of the wanted page as a string, or the mw.title object of the wanted page.

This module can also be used via templates using #invoke:, like the following: {{#invoke:Sandbox/Aidan9382/CodeAnalysis|main}}. The module will then produce a wikitable of anything it notes within the code. An argument can be provided to the first positional parameter to specify a certain page to analyse.
