I have been thinking along similar lines, and made an implementation for beep that works with a handler. It's not yet committed, as I was trying to make an LCL plugin which would work on Linux/X11.

[fpc-pascal] Generic type declaration example versus manual.
Hello.
In example tgeneric16.pp (from FPC 2.2.4 sources) the generic type
TStack is declared as:
type
{ TStack }
generic TStack = class(TObject)
public
procedure Clear; virtual;
destructor Destroy; override;
end;
Though in FPC manual type is described as:
type declaration: identifier = type ;
type: simple type
string type
structured type
pointer type
procedural type
generic type
specialized type
type identifier
generic type: generic identifier < template list > = generic class ;
Following the manual, the type identifier is thus declared two times:
- in type declaration
- in generic type
Like:
TStack = generic TStack = class(TObject)
public
procedure Clear; virtual;
destructor Destroy; override;
end;
The syntax found in the example doesn't take care of the first
identifier in type declaration.
May I suggest the following:
TStack = generic class(TObject)
public
procedure Clear; virtual;
destructor Destroy; override;
end;
This syntax looks like more Pascal conformant, i.e. it doesn't brake
Pascal type declaration "identifier = type;"
And this prevent the succession of greater and equal characters in
"generic TStack=class(TObject)" which may be considered as greater
or equal ">=" by the compiler.
For sure, the simpler would be to change the manual ;-)
What are your feedbacks ?
Regards, Pascal.

Re: [fpc-pascal] Generic type declaration example versus manual.
I haven't used generics in FPC, but really have to ask, is they keyword generic really necessary? Shouldn't generics be declared like this: type TList = class private ... public function Add: T; procedure Remove(Item: T); property Item[Index: Integer]: T read Get write Put; default; end; I believe this makes the most sense, and it's also how they are declared in Delphi. It would be a real shame to create more Delphi incompatibilities. On Sat, Nov 21, 2009 at 1:24 PM, Micha Nelissen wrote: > Jonas Maebe wrote: >> >> tgeneric16.pp is not an example, it's a test.
