const string type parameter reification

[Stephane Le Dorze]

anyone knows how to reify a const string as a type parameter (using a variable) during a macro class creation? (not sure it's possible syntactically).

I would like to do something like:

macro class Bar {

..

function myMeth() : Foo<$cstringName>

...

}

Instead of building it by myself like :

var myType = TPath({

      name : "Foo",

      pack : [],

      params : [

        TPExpr({

          expr : EConst(CString(cstringName)), pos : cpos

        }),

      ]

    });

macro class Bar {

..

function myMeth() : $myType 

...

}

Morph being of the form:

class Foo<Const> {

...

}

Thanks in advance,

Stephane

With strings it does work like so:

  macro class Bar {

    function myMeth() : Foo<'$cstringName'>;

  }

With other types of constants, I think you will have to do it by hand.

Best,

Juraj

Oh thank you Juraj!

Too bad for the other forms... have this already been discussed to death or should I open an Issue?

Best,

Stephane

Not to my knowledge. I guess sophisticated type reification is just not that common ;)

Oooh, does it work for class names?

eg. macro class '$cstringName' { }

var newClass = macro class $clazzName {

    ....
