Navodila za razhroščevanje WvdS FPC RAD Studio razširitev in aplikacij.
Razhroščevalno beleženje zahteva dva pogoja:
-dDEBUG–debug{$IFDEF DEBUG} procedure LogDebugTrace(const AMessage: string; const AArgs: array of const); begin if not DebugEnabled then Exit; WriteToDebugLog(Format('[%s] %s', [ FormatDateTime('hh:nn:ss.zzz', Now), Format(AMessage, AArgs) ])); end; {$ENDIF}
debug-yymmddhhnnss.log~/binaries/logs/~/sources/Za podrobno razhroščevanje s skladom klicev:
procedure LogDebugTrace(const AMessage: string; const AArgs: array of const); var CallStack: string; begin {$IFDEF DEBUG} if not DebugEnabled then Exit; (* Sklad klicev z get_caller_frame / get_frame *) CallStack := GetCallStackTrace; WriteToDebugLog(Format( '[%s] %s'#13#10 + ' at %s'#13#10 + ' Parameters: %s', [ FormatDateTime('yyyy-MM-dd hh:nn:ss.zzz', Now), Format(AMessage, AArgs), CallStack, FormatParams(AArgs) ] )); {$ENDIF} end;
function GetCallStackTrace: string; var Frame: Pointer; Addr: Pointer; Info: string; begin Result := ''; {$IFDEF DEBUG} Frame := get_frame; while Frame <> nil do begin Addr := get_caller_addr(Frame); Info := BackTraceStrFunc(Addr); (* Format Unit:Line *) if Info <> '' then Result := Result + ' at ' + Info + #13#10; Frame := get_caller_frame(Frame); end; {$ENDIF} end;

Ker je koda transpilirana (Pascal → JavaScript), prelomne točke delujejo samo z izvornimi kartami:
-Jm (generiranje izvorne karte)Izhodni kanal WvdS prikazuje sporočila med izvajanjem:
View → Output// V kodi LogInfo('Informacijsko sporočilo'); LogWarn('Opozorilno sporočilo'); LogError('Napaka: %s', [E.Message]);
Za nizkonivojsko razhroščevanje:
Help → Toggle Developer ToolsDiagnoza:
# Preverite dnevnike razširitve code --verbose --log trace
