Diagnostics parsing is broken for GHC versions after 9.6.*

[EduardSergeev]

Status

• A workaround is available
• A fix is written
• A fix is released
• The fixed version is on the marketplace.

---

• Version of vscode-ghc-simple: 0.2.3
• Version of VSCode:
• Version of Haskell-related tools:
  • GHC: 9.6.3
  • Stack: 2.13.1
  • Cabal: N/A

Steps to reproduce

Open Stack project targeting GHC version newer than 9.6.* (e.g. 9.6.3) which generates warning (and probably some errors?). Check how these warning are displayed in PROBLEMS tab.

When the same project targets GHC versions 6.4.* or older all warning are correctly parsed and displayed. However warning (and probably some errors?) generated by GHC 9.6.* are not being parsed by vscode-ghc-simple, e.g.:

Workspace

I believe any Stack project targeting newer version of GHC will have this problem, e.g. this project's branch which targets GHC 9.6.4 generates a lot of warnings which cannot be parsed by the latest version of vscode-ghc-simple
