jint.commonjs's Issues

MissingMethodException?

Writing a simple VSMac Jint/Jint.CommonJS console app, and I'm running into a MissingMethodException being tossed from this code:

var cjs = engine.CommonJS();
cjs.RegisterInternalModule("console", typeof(Console));

This is with 3.0beta of Jint, if that makes a difference.

The exception looks like:

System.MissingMethodException: "Method not found: 'Jint.Native.JsValue Jint.Native.JsValue.op_Implicit(Jint.Native.Object.ObjectInstance)'."
  at Jint.CommonJS.ModuleLoadingEngine.RegisterInternalModule(String id, Type clrType)\n   at JintExplorer.Program.Main(String[] args) in /Users/tedneward/Projects/JintExplorer/JintExplorer/Program.cs:46

Any insights appreciated, particularly if this is a user bug. (Just started playing with Jint.CJS.)

Tests covering same behaviour

Hi,
in ModuleLoader.Tests.cs the test methods RunMainShouldLoadAnIndexFileOnDisk and RunMainShouldLoadAnIndexFileOnDisk seem to cover the same behaviour. Just wanted to let you know in case this was not intended.

node Require

Hello,

Thank you for providing this extension to Jint!

You are not able to load npm packages with Jint.CommonJS. Although the library loads modules in relatively the same format at NodeJS's Module specification, there are some important distinctions. The library does not support node_modules, or reading package.json files for modules.

Do you know of any Jint extension that can handle basic node requires (no package.json)?

Thanks,
Ben

Problem trying to create an instance of function class from a js module.

Im trying to create an instance of a function class from a js module and use it.

I have tried to do the following:

var AHRS = scriptEngine.CommonJS().RunMain(path + folder + "node_modules/ahrs/index");

where I assume AHRS should contain the following function class called "AHRS": https://github.com/psiphi75/ahrs/blob/master/index.js used like so: https://github.com/psiphi75/ahrs

I run a second snippet with the same ScriptEngine:

var value = scriptEngine.GetValue("update").Invoke(AHRS, 0, 0, 0, 1, 1, 1, 2, 2, 2);

Which looks like:

function update(ahrs, gX, gY, gZ, aX, aY, aZ, mX, mY, mZ) {
    // let ahrs = new AHRS({ sampleInterval: 20, algorithm: 'Madgwick', beta: 0.4 });
    // ahrs.update(gX, gY, gZ, aX, aY, aZ, mX, mY, mZ);
    // ahrs.getEulerAngles()
    const s = new ahrs(null);
    return JSON.stringify(s);
}

where I am unable to call method on the AHRS instance. Logging the return of update - I get an empty object: {};

Any help is very much appreciated. My overhead goal is to use the AHRS javascript library in C# in a Xamarin.Forms app.
