DanielRosenwasser · 2024-06-26T23:06:14Z

I think we will schedule this for a follow-up patch. I want to get 5.5.3 out today.

sandersn · 2024-06-27T15:30:55Z

I think this is good enough to merge once @a-tarasyuk has a chance to confirm that the scanner changes are infeasible (or, if they're feasible, to make the changes). Can you check whether adjusting fullStartPos after * does actually cause * appears after names?

a-tarasyuk · 2024-07-01T21:41:16Z

Modifying fullStartPos in the scanner might lead to a * being added after the name or \n* being included in the node range.

/*HIGHLIGHTS*/<|[|{| kind: "reference" |}foo|]: string;
//  *   |>

The first issue can be fixed by adjusting fullStartPos for identifiers. However, the second case won't stop at the ; token because \n* is considered a valid leading asterisk within the node range...

sandersn

Given the complexity of a better fix, let's take this with the idea of improving the scanner's ability to skip * in the future.

(Based on discussion between me and @jakebailey .)

@a-tarasyuk would you mind bringing this branch up to date with main?
