How to get the script line number when an exception occurs

[chicknsoup]

Hello,

When running a python script in background without TPythonGUIInputOutput, it's difficult to debug when exception occurs. In this case, how to get the stacktrace/line number?

Thank you

When you execute code, say with ExecString, CheckError is called at the end which on exception updates PythoneEngine.Traceback. and raises a suitable EPythonError descendent exception.

type EPythonError = class(Exception) public EName : string; EValue : string; end; TTracebackItem = class public FileName : string; LineNo : Integer; Context : string; end; TPythonTraceback = class public property ItemCount : Integer read GetItemCount; property Items[ idx : Integer ] : TTracebackItem read GetItem; property Limit : Integer read FLimit write FLimit; end;

So what you typically do is:

try ExecString(Code, FileName); except on E: EPythonError do begin // Inspect E.EName and E.EValue // Inspect the GetPythonEngine.Traceback end; end
