Hello.

Following program:

program a;
{$mode delphi}
type
  generic TGen<T> = class end;
  TSpc = specialize TGen<Integer>;
begin
end.

compiles with FPC 2.4.2, but not with 2.5.1 rev. 17306:

a.pas(4,11) Fatal: Syntax error, "=" expected but "identifier TGEN" found
a.pas(5,21) Error: Identifier not found "specialize"
a.pas(5,21) Error: Error in type definition
a.pas(5,21) Fatal: Syntax error, ";" expected but "identifier TGEN" found

"generic" and "specialize" are not allowed in delphi mode in 2.5.1 but they are required in 2.4.2.

Is this a conscious change? There is no mention of this on Wiki User Changes 2.4.4 or User Changes Trunk pages.

In mode delphi FPC understands delphi generic syntax. I did not write a line to the

User Changes Trunk because this work is not finished. But looking at my free time I don't think it will be finished by me, so I will add a note there today.

Best regards,

Since FPC in Delphi mode supports Delphi style generics syntax, FPC's own generics syntax was removed from this mode. You can still use it from ObjFPC mode.

OK.
Thanks.

Would you mind if I'd try to continue/finish that work?

I created a branch here: > http://svn.freepascal.org/cgi-bin/viewvc.cgi/branches/svenbarth/generics/ Yes, but please wait with the start :) First you need to read generics related threads on the core list. There were some unsolved problems on which I stoped my work.

And here I thought I could jump into the cold water :P

Where can I access the core list archive?

Sven
