Compiler Message Suggestion by Conor Flynn

Hi all,

Just a quality of life suggestion for compiler error messages. Often it is hard to pinpoint the exact source of an error in code when debugging. I was wondering how easy it would be to implement line numbers into error messages for easy debugging. For example:

/* rather than:

    System.ArgumentException: symbol must not contain the characters '|' or ' '.

    Parameter name: symbol

    <OMITTED BACKTRACE>

    at QuantConnect.Algorithm.QCAlgorithm.AddOption (System.String underlying, System.Nullable`1[T] resolution, System.String market, System.Boolean fillDataForward, System.Decimal leverage) [0x0007b] in :0



   it would state:

    System.ArgumentException: symbol must not contain the characters '|' or ' '.

    Parameter name: symbol

    <OMITTED BACKTRACE>

    on line 562: at QuantConnect.Algorithm.QCAlgorithm.AddOption (System.String underlying, System.Nullable`1[T] resolution, System.String market, System.Boolean fillDataForward, System.Decimal leverage) [0x0007b] in :0

*/

Hopefully that is an easy change if viable.

Thanks for the suggestion. We show the line numbers as much as possible but sometimes we don't have the information.

In this case, the error is happening in the backend of LEAN not near the algorithm level so no line numbers are shown. We will think about this however maybe there is a way to know more.
