FClass<TArray<Char>> can not be compiled
« on: October 09, 2024, 08:16:36 pm »
Code: Pascal  [Select][+][-]
  1. procedure foo;
  2. var
  3.     myQChar: QChar<TArray<Char>>;
  4. begin
  5.     myQChar := QChar<TArray<Char>>.Create([' ', ' ']);
  6. end;

I get error at compile when using the above code.

TArray<Type> is a generic.

The only true wisdom is knowing you know nothing

Hi
@Thaddy: I think it's his own compiler  ...hence, I haven't the foggiest...

If it ain't broke, don't fix it ;)

what is a qchar? Benny?
If I smell bad code it usually is bad code and that includes my own code.

Hi
It's some kind of nonsense, he dreamed up last time he was smoking the big pipe  :D
As far as I can read of his stuff, most of it belongs in /lalalala-land/ Sorry mate, that's just my opinion...
Regards Benny

eta: maybe his idea of a managed string type, gawd help us...

Hi
@TRon: I know, I use QT daily, but his nonsense has nothing to do with qt-strings...

I know that the snippet still makes no sense cdbc but he seem to have been working on implementing his own (qt) classes (at least that is what I remembered from a previous conversation with TS).

@paule32:
it might perhaps help if you could express what was expected that the code-snippet would do (or is suppose to do).

Afaik that is fixed in trunk  . But I had it for a type declaration, don't know about code on the fly, I never did that.

QChar
Ah, I see. Why not use UnicodeChar? That is a fundamental type.
Hm, that is just size 2, - I knew that, sigh - so fails. It should be four. Did somebody complain already, because that is a bug and covers just UCS2.
But there is ucs4char. Delphi behaves the same, though.

I use fpc 3.2.2 for using own classes that are similar to Qt 5 Framework.
I use fpc with gnu c++ 20, to get a code base that can be use from fpc, and g++.
The original idea was, to bundle VCL with g++, to form g++ in a C++ Builder like Compiler.
But I could use Com+.
But this is Windows depend, and I am not a fan of Com+.
So I do experiment for cross-development.
You can follow the process at my https://github.com/paule32/fpc-qt account.

Code: Pascal  [Select][+][-]
  1. procedure foo;
  2. var
  3.     myQChar: QChar<TArray<Char>>;
  4. begin
  5.     myQChar := QChar<TArray<Char>>.Create([' ', ' ']);
  6. end;

I get error at compile when using the above code.

The compiler does not yet support nested specializations in mode Delphi. Either use mode ObjFPC, then you can do specialize QChar<specialize TArray<Char> > (note the space between the two >). In mode Delphi you need to declare the array specialization separately (that solution can of course be done in mode ObjFPC as well with the appropriate specialize placements):

Code: Pascal  [Select][+][-]
  1. type
  2.   TCharArray = TArray<Char>;
  3. var
  4.   myQChar: QChar<TCharArray>;
  5. begin
  6.   myQChar := QChar<TCharArray>.Create([' ', ' ']);
  7. end.
