three.js has functions missing in externs file #292

I think the three.js library has some missing functions in the externs file, but I´ve yet to understand the proper way to encode the functions that are missing in the externs file. Here is what I am experiencing:

I have the following Three.js code:

(let [r (THREE.WebGLRenderer. #js {"canvas" canvas-el
                                     "antialias" true
                                     "alpha" true})]
    (.setClearColor r 0xffffff 0)
    (.setSize r width height)

This works fine in non-advanced compilation but fails when using :advanced.

This is what is generated with :advanced

{var pp,qp=new THREE.WebGLRenderer({canvas:gp,antialias:!0,alpha:!0});qp.zd(16777215,0);qp.Ad(hp,ip);pp=qp}

This is the error in the browser console:

Uncaught TypeError: qp.zd is not a function

The three.ext.js file contains the following:

"WebGLRenderer": function () {},

The three.js file contains the following:

THREE.WebGLRenderer = function ( parameters ) {
     // Lots of stuff

    this.setClearColor = function ( color, alpha ) { ... }


How is the externs file supposed to look like in order to keep the setClearColor function?

I figured it out, there are indeed lots of functions and variables missing in the three.js externs file. I'll submit a pull request once I find a way to automatically identify the missing elements.

Three.js has was updated recently and the externs re-generated. But looks like for example setClearColor is still missing: 3993894

@harrio Have you had problems with the generated externs?

No. So probably didn't use the affected stuff. Three.js seems to be problematic for extern generators: issue Even if I didn't use that generator here. Maybe the missing stuff has to be added manually.
