add namespace when converting to js files

[chengtie]

I use js_of_ocaml to convert an analyzer coded in OCaml to analyzejs.js. Then I use <script src="analyzejs.js"></script> in my website to load it, and call the wrapped functions on the website.

Now, I have a new version of the analyzer, let's say analyzejs-new.js. I want some part of the website to use the wrapped functions of analyzejs-new.js, and some part of the website to use the wrapped functions of analyzejs.js. As functions in analyzejs-new.js and analyzejs.js share the same name, I would need namespaces to specify if I want to use f() of analyzejs-new.js or f() of analyzejs.js.

It seems that it is complicated to add namespaces on the side of the website, when loading these 2 files. I would like to know if it is possible to add namespaces on the side of js_of_ocaml when these 2 files are being converted.

Could anyone help?

How do you export f in analyze.js ?

I tried adding an example doing what you want in
c51a161.

Ideally, the logic should be much simpler, I'm working on it.

@hhugo Normally, I use Js.Unsafe.global##.f := Js.wrap_callback(fun ...) to export f in analyze.js.

Can you take a look at the example in #1201 and tell me if that is what you're looking for ?

Note that Js.Unsafe.global##.f := (...) is not going to work if you use --wrap-with-fun, you should use Js_of_ocaml.Js.export "f" (...) instead
