Sorry, I'm not sure what you're asking. Personally, I only use auto for unweildly/very long typenames, like std::map<std::string, MyClass>::const_iterator, for example.

What's difficult about your code is that it's not clear what Get() returns (from just reading the function F()). If it were perhaps more appropriately named, it would help improve the clarity of your code.

Completely ignore this post! I didn't realize this was the AngleCode forum... sorry for being so blind! I thought FDsagizi might be asking what people thought of auto and if it was good to use it in the following code. I realize now that I wasn't even remotely close (and where's GameDev's embarrassed smiley!?).

Sorry, I'm not sure what you're asking

I think 'auto' is a useful feature in C++, especially when writing template functions, or even macros.

In AngelScript I can see 'auto' being useful for the mixin classes, and as such I have it on my to-do list to study the possibility of implementing it, however its currently very low on my priority.

It's not an easy feature to implement. It would reverse the order things are evaluated in the compiler right now, as it is necessary to first determine the type of the expression and only then declare the actual variable.

Sorry, I'm not sure what you're asking

We're in the AngelCode sub-forum -- he's asking about adding C++0x-esque auto to AngelScript.

Oh... wow... I'm an idiot. Sorry folks!

AngelScript's mixin classes are generics, and auto can definitely come in handy in such cases. Example:

mixin class MyGenericImpl
{
   void func()
   {
      auto c = a + b;
      DoSomething(c);
   }
}
 
class A : MyGenericImpl
{
  int a, b;
}
 
class B : MyGenericImpl
{
  float a, b;
}

The variable c in the func() method will have the int type in class A, and the float type in class B, as the code for the mixin class is only compiled in the context where it was included.

In my opinion, auto is not supposed to be used to infer long type names. That should be done with the use of typedefs to declare a shorter alias for the long types. Currently AngelScript only supports creating aliases for primitive types with typedefs, but eventually I'll allow any type to be used in typedefs.

The use of auto outside generic code is not something I recommend, for much the same reasons that saejox mentioned. It would make it much harder to know what type is actually acted upon, thus make it more difficult to read the code.

1. coming. delegates and also the opCall operator (same as C++ operator())

2. coming. though probably only as registered classes

3. I would like to do this, but I really don't see a proper solution for it.

4. probably one day

5. no. I provide them as add-ons because not everyone has the same needs. The add-ons are as good as built-in, but more flexible as you can easily change them the way you want. The engine core shall provide the necessary hooks for the add-ons to work seemlessly

6. one day

7. add-on

8. one day

9. add-on

10 & 11. maybe. I do have an interest in adding support for pure pointers again, though with an engine property to turn it off where sandboxing is required

12. as much as possible in add-on, but with necessary support from engine

13. add-on with support for incremental compilation in the engine
