At the present state of fpc compiler it is technically imposible to

delphi rtti unit. To do this you need first to implement the next
compiler features:
1. Extended records (methods, class operators)
2. Generics as in delphi
3. Attributes
4. scopeable RTTI ($RTTI directive)
I mean that for implementing RTTI unit compatible by interface with
delphi you need that 3 features I wrote about. Or how you will port for
example TValue record:
TValue = record
private
function GetIsEmpty: Boolean;
...
procedure Get<T>(out Result: T);
public
// Easy in
class operator Implicit(const Value: string): TValue;
...
1. GetIsEmpty - a method in a record.
2. Get<T>(out Result: T) - generics as in delphi
3. class operator Implicit(const Value: string): TValue - delphi class
operators
I was wrong about Attributes - seems they are not used in the rtti unit
interface.
Best regards,
Paul Ishenin.
