Making backend functions available under a global object instead of using webui.call("fn_name_string", ...args)

[ttytm]

I think the following change could add a lot of convenience.

If we bind a C function like the following:

webui_bind(w, "myStrFunc", my_str_func);

It could became available as a JS function under a global object.

// Instead of calling it via
webui.call("myStrFunc", myArg)
// Call the function from the global object or window
webui.myStrFunc(myArg)

By default webui could be used as object name. But there should be an api that allows to customize the name of the object and to set it to an empty string, then it would just be the window object and the it would become a global function.

I really liked this idea, Thank you for pointing this out 👍
Implemented (87a3a4f).

This is beautiful!
Now from JS:

my_backend_func(arg1, arg2).then((response) => {
    // ...
});

Implemented (46c5125).

The only issue with this mechanism is it may cause conflict between the back-end function names and global names. To solve this, WebUI Bridge will check if a global object already exists before adding it... However, webui.my_backend_func() and webui.call(my_backend_func) still work anyway.

Having it available via webui. is a good default I think 🙂 👍 .

What do you think about giving the power to the user to set the object name?

Then something like webui_set_callback_object could take a char that would be used as object name.
So when setting webui_set_callback_object("ui") it would become ui.my_backend_func. An empty string webui_set_callback_object("") would cause things to become avilable via the global scope my_backend_func.

I don't think webui_set_callback_object is necessary. The user can easily set in JS const ui = webui; if needed.

However, those are always available in JS:

webui.my_backend_func();
webui.call(my_backend_func);

This available if my_backend_func object does not already exist globally in JS:

my_backend_func();

Very good. Thank you!
