Hi all!

To FPC developers: FPC trunk has a way to enumerate all record fields and get their names?

For example:

type
  aRec = record
    a:String;
    b:integer;
    K:Int64;
    W:Single;
  end;

I want to do something like this:

for f in aRec.Fields do
  writeln(f.Name);

and get the output

a
b
K
W

I want a way to simple stream records to JSON, without the need of writing a customized streamer for each record type.

Using RTTI I can count the record fields, but until now, I can't find a way to get the field names.

Best regards,

More is not possible as of now. Only once the Extended RTTI is supported this will be possible.

Thanks for the clarification!
