[fpc-pascal] procedure that accept generic types?

Hi There, I try to write a procedure with generic parameters, but failed: type generic TArrayT = array of T; procedure ProcessArray(arr: TArrayT); begin end; The compiler said Generics without specialization cannot be used... But if I specialize the parameter then this procedure is

Re: [fpc-pascal] procedure that accept generic types?

Thanks. This is sort-of too verbose when use. I have no comments about how to define it, but when use it, can we just use: ProcessArray(someintarray); ? The complier should be able to specialize it implicitly because it knows someintarray is array of integer? alternatively, how about

Re: [fpc-pascal] procedure that accept generic types?

Hi Sven, Not to debate the syntax, but just ask :-) 1) in my second example: proc_ints: specialize ProcessArrayLongInt; it is specialized. Why this is still not consistent ? 2) in delphi mode, specialize is not required anywhere, right? If so, can you write an example of your new proposal in

[fpc-pascal] Runtime error 217 on array of Variant

Hi there, I would like to use TVarRec as Variants, after some googling I found this: http://stackoverflow.com/questions/3733640/how-to-convert-between-tvarrec-and-variant However, it generated Runtime error 217. My original code (runs OK) is: 1 program test; 2 {$mode objfpc}{$H+} 3

[fpc-pascal] Re: Runtime error 217 on array of Variant

I found the problem myself. You have to add uses Variants to eliminate the problem. So now my questions are: 1) why the Variants unit is required? What does it do? 2) is there any performance penalty using Variant than TVarRec? Thanks! 2013/9/5 Xiangrong Fang xrf...@gmail.com Hi there,
