As I wrote I updated may implementation of Delphi classes to gpc-20050331. Now, I have put a patch at: http://www.math.uni.wroc.pl/~hebisch/gpc/delphi3.diff With the patch, when one chooses Mac Pascal as a dialect, object model should be compatible with Mac Pascal: -- objects are pointers -- all methods are virtual (that was already implemented in gpc-20050331) -- overriding a method requires `override' keyword -- you can allocate memory for objects with `New' and deallocate it with `Dispose' In default mode the `class' keyword is recognized and allows you to declare Delphi classes. ATM Delphi constructors works only in simplest case (you can not call a constructor inside a (different) constructor). Destructors do not deallocate memory (but `Dispose' applied to a Delphi class will deallocate memory). Also, Delphi builtin `TObject' is unimplemented. This is experimatal (and incomplete) implementation. I would like to get some feedback about missing features. Also, if I got semantics of implemented parts correctly. ATM I know only about one missing Mac objects feature (which is almost surely due to my lack of knowledge about Mac Pascal): GPC requires all methods to be defined in the same unit as the object (TCL sources implement methods in different units). And of course test programs are welcome. -- Waldek Hebisch hebisch@math.uni.wroc.pl
