New Post: Returning syntax error location

While working on a testing framework that executes JavaScript tests, I wanted to have ClearScript tell me the location of the syntax errors it found. It doesn't.

This is in a non-browser environment. I thought version 5.4.1 would fix it. It doesn't.

A colleague debugged the DLL and discovered that the GetDetails() method in the WindowsScriptEngine class (WindowsScriptEngine.Site.cs) will return either a stackTrace or an error location but not both.

The answer was to rework the try block to be:

try

                {
                    var errorLocation = GetErrorLocation(error);
                    if (!string.IsNullOrWhiteSpace(errorLocation))
                    {
                        message += "\n" + errorLocation;
                    }

                    var stackTrace = engine.GetStackTraceInternal();
                    if (!string.IsNullOrWhiteSpace(stackTrace))
                    {
                        message += "\n" + stackTrace;
                    }

                    return message;

                }

Now it returns both in one message.
