Add ability to get lines/filename for Span in smir #116630

ouz-a · 2023-10-11T09:49:46Z

Wasn't sure about how to structure lines, so went with safest option, also I'm not sure why span_to_lines returns vec.

@celinval does this format contain what you need?

What are you planning on using these for? If it's just for diagnostics, does the opaque rendered version suffice?

document whether the first line is 0 or whether it is 1. Similarly for col

made them start from 1 now

I would suggest that you return something similar to span_to_location_info.

It basically returns the line + column for beginning and end of the span.

I modified LineInfo struct so it looks like line,col:beg; line,col;end

Perfect! Thanks

@oli-obk, we use the output for diagnostic but also in our vscode extension, code coverage and the trace generator. So ideally we would like to be able to map beginning and end of a span to the exact location in a local file.
