@:from static macro function (abstracts)

[Laurence Taylor]

I can’t find enough info…

 @:forward abstract TestMacroFrom(String){
  @:from static public macro function fromStringExpr(str:haxe.macro.Expr):haxe.macro.Expr{
    return macro "Nothing";
  }
}

I would think that might work, but doesn’t. In any case, I’m not sure how to get the function to trigger in the first place.

Any one know what the limitations are?

regards,
Laurence

Not sure, I used it and it works for me in some other (more complex) context,
but in your case:
@:forward abstract TestMacroFrom(String) from Dynamic {
...
seems to work.

Thanks, I think I see how that might work.

As I wrote, I'm not sure if it's supposed to be used like this. I used it some
other context (an abstract with parameter <T>) where I didn't need `from
Dynamic`.
Some documentation would be helpful...

It's early days, I think. post some issues, see what turns up.

It looks like when you pass an abstract, you get the expression for 'this' that would be passed to the abstract constructor.
