npm i ioscript

let IOScript = require("ioscript");

Basic usage:

let sandbox = IOScript({
    onError: function(isCore, error) {}, // isCore ? ioscript error : provided script error
    pure: true, // whether internal scopes inherit parent scope variables (pure by default doesn't)
    maxOps: -1, // max amount of ops triggers
    opTriggers: [], // ops that trigger ops count
    noOpTriggers: [], // ops that don't trigger ops count
    debug: false, // displays debugging information as it parses and runs through a script
    cleanEnv: false, // true if you dont want to expose basic properties/methods, (isNaN, Array, Object, etc...)
    globals: {}, // global variables provided for inside the sandbox (functions, objects, anything...)
});

sandbox.run(scriptName, scriptCode); // run a script
sandbox.global; // global scope inside sandbox
sandbox.ops; /* {
    current, // view the current op count
    limit, // view/set the op limit
    clear, // clear the op counter
} */
sandbox.types; // Array of op trigger types
