Delphi #IF(DEBUG) equivalent?

Question

Is there a Delphi equivalent of the C# #if(DEBUG) compiler directive?

Answer 1

DebugHook is set if an application is running under the IDE debugger. Not the same as a compiler directive but still pretty useful. For example:

ReportMemoryLeaksOnShutdown := DebugHook <> 0; // show memory leaks when debugging
