Feature request: expose source file and line numbers of declarations #195

Closed gfraiteur closed 11 months ago

gfraiteur commented 11 months ago

In some scenarios like logging, it is useful to get the source file and line number. It could be exposed on the IDeclaration interface.

Where exactly can I see how to implement this great change?

gfraiteur commented 11 months ago

There is no example, but in your case here is what you want:

var sourceSpan = method.Sources.SingleOrDefault ( s => s.IsImplementationPart )?.Span;

then use sourceSpan?.FilePath, sourceSpan?.StartLine, ...
