Re: [fpc-devel] Ref documentation doesn't mention deprecated keyword

As far as I know the deprecated keyword can only be used on methods in a class, not the class itself. The latter would be very handy. I am wondering why not to try? type TMyClass = class(TObject) end deprecated; TMyClass.Create; SomeUnit.pas(x,y) Warning: Symbol TMyClass is deprecated As I know you can deprecate any symbol and even unit.

In our previous episode, Dani?l Mantione said: How do you mark a unit as deprecated?

Graph remains a supported unit. It may not be the best idea for new code, but there is no recommendation against using it. It is also more a hint that something is going on than a final precisely described verdict. Like while e.g. unit libc is deprecated (stronger, IMHO never was anything else), but I don't have plans to remove it as long as it is usable and maintainable. I just want to avoid that people grep the sources, find calls there and start using it. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

2009/6/1 Paul Ishenin i...@kmiac.ru: Have you tried as I wrote? My mistake, I typed... type TMyClass = class(TObject) end; deprecated; instead of... type TMyClass = class(TObject) end deprecated; I used deprecated like you do for methods... after the last semi-colon. Seems for unit this is not availble if fpc. Delphi allow use of deprecated and platform marks for units too. That would be nice for FPC as well... ;-) The code I'm working on (tiOPF) is shared between Delphi and FPC compilers, so if deprecated is supported on both, that would be ideal (though not the end of the world if it's not).
