The Init Script System ​

Each package in JSCore has 3 entry points - init.js, index.js and stop.js, but JSCore (the mod) is not aware of this, for all it knows it runs the main init.js at start and stop.js at stop.

The Main Init Scripts ​

The main init.js looks for packages in /modules/ when the game starts, and runs their respective init.js in the order of dependencies first, then the dependent.

stop.js runs the stop scripts in the reverse order.

Prelude ​

Prelude is a familiar concept present in most programming languages. For example Java imports java.lang.* for every file so names such as java.lang.String can be referred to by just String. You could imagine they've added the line import java.lang.* before every Java source file.

Things such as console, Promise, setTimeout and require are defined in every file in the same way - if the package depends on rinode.

If package A has a prelude.js and package B is dependent directly or indirectly on A, then prelude.js from A runs before each file in B. A prelude file looks something like this.

js
// prelude.js
prelude.eval("let { addEventListener } = require('listener')");

Which imports addEventListener to the file.

Checking Path ​

Since the content of prelude is ran on another file, you can check the path of the file with module.path, which returns the path of the file that is being ran as a Java list.
