How to call "main" myself?

[Danilo Guanabara]

Is there any way to run the code exactly when I want it to run and not just when the runtime was loaded?

What do you mean by 'when the runtime was loaded'?

I use --pre-js and --post-js to have fine-grained control over running order.

For example, take a look at https://github.com/aidanhs/emtcl/blob/master/js/preJs.js and https://github.com/aidanhs/emtcl/blob/master/js/postJsTcl.js

You could modify this by putting the stuff in post-js inside a function itself which you could insert into window as 'initemtcl' or something similar.

Honestly, I'm not sure if those two links are the best way to do this kind of thing any more. I created this structure of pre/post-js about a year and a half ago and I've just copied and pasted since then. For example, I don't know if emscripten still pollutes `window.Module`.

Hopefully it gives you a starting point - basically just wrap everything in a function and run that when you want to kick off.

Another option is to build with  -s INVOKE_RUN=0  so that we don't run the project automatically. Then just call  _main()  yourself (if you want to pass arguments, can use ccall).

I read somewhere that the main function is executed in the exact moment that the runtime is loaded and ready. But anyway...

The only thing that I need is to start Emscripten's execution, for example, when some UI event occurs.

I am not sure if your solution will accomplish that, it seems that it only affects the execution order.

Thanks, Alon! That's what I was looking for.

As a general point, if you wrap some JS code in a function, *nothing* will be executed until you execute the function. Having pre and post js look like "function abc() {" and "}" accomplishes this.

Yeah, that's a more guaranteed simple way to do this. But it does mean that asynchronously loading the memory init file etc. will only happen when you actually call it. If that delay is not a concern, though, then definitely this is the easiest way.
