Research direction

Start by reproducing the provided union-type snippet in VS Code 1.84.1 on macOS and inspect the TextMate scopes shown in the report. Trace the TypeScript TextMate grammar rules that classify data, arg, and their types; done means equivalent constructs receive consistent syntax highlighting without changing unrelated TypeScript scopes.

Description

Does this issue occur when all extensions are disabled?: Yes/No

  • VS Code Version: 1.84.1
  • OS Version: macOS 14.0

I have the following TypeScript code, and its return type is a union type. However, the colors for syntax highlighting are inconsistent in the same location (data and arg). I found that this is due to their different TextMate scopes.

declare function getCb():
  | { data: string; cb: (arg: string) => void }
  | { data: number; cb: (arg: number) => void }
