Global error handler

[Aleksandr Kuzmenko]

Implemented in e21a2e0

PHP provides an ability to globally handle errors, warnings and notices.
Need to implement access to this function from Haxe side.

Well, the error_handler has a pretty complicated signature and I'm not sure what this errcontext really is and also it can return a string or an array but basically it would be something like this:

@:phpGlobal
extern ErrorHandling {
  static function set_error_handler(handler:Int->String->?String->?Int->?NativeArray->Bool, types:Int):String;
}

The problem is that you can't pass in a function directly here, I think only a closure would work. Maybe a Callable<T> abstract over Function would be a good idea, that converts static and instance functions to arrays? Do you handle function passing already in the generator?

[Aleksandr Kuzmenko]

I don't see any problem here.
set_errror_handler can accept any closure. And closures should be generated correctly (not yet, but it's in the roadmap).

[Andreas Mokros]

Yeah, but you can't pass obj->func or Class::func directly, can you?

[Aleksandr Kuzmenko]

I think those will be wrapped in anonymous functions :

var q = MyClass.method;

$q = function () {return MyClass::method()};

[Andreas Mokros]

I had this idea as well, but there was a problem, but I don't remember (of course).
What about obj->func?

[Aleksandr Kuzmenko]

$q = function () use ($obj) { return $obj->func(); }
