There isn't really a current API guide, but I've found studying Michael's code (particularly the .js and .htm files in MoI's commands directory) to be quite helpful in developing a sense of how the API works. The v3/4 release notes also contain numerous hints about scripting and the API as do the forum posts.

Thanks for the tips, Larry! I will spend more time poking around in the commands directory and reading the release notes in more detail.

Hi Teddy, there is also some info here but not much sorry:

Going through existing scripts from others has been very helpful.

What version of the Javascript/ECMAScript interpreter is built into MOI? I've found that newer language features like the "for-of loop" don't seem to be supported.

Thanks,
Teddy

I believe it is ECMAScript5 = ECMAScript2009 = Javascript5 = ES5

Babeljs.io can be used online to convert ES6 to ES5. Use the "try it out" tab.

ECMAScript6 has the confusing year 2015 name.
ECMAScript6 has "let" and (weird to me) function naming, and weird double arrows. And I think Cosh() and Sinh().

Hi Teddy, yes I think it only supports ECMAScript5 like Brian writes above.

The interpreter is JavaScriptCore that comes with QtWebKit with Qt 5.4.1 .

Hi Michael,
I wanted to use Math.js for complex numbers and elliptic functions, and possibly other functions, but notice that it is
at least ES6 (ECMAScript 2015. Do you think MoI v5 may have ES6 or later compatibility?

I guess I can translate some of Math.js to ES5...

- Brian

Hi Brian, it will take quite a bit of work to update the scripting engine so I'm not sure when that could happen. Probably not for MoI v5.

Thank you Michael.
