The vscode integration was working just fine until this morning; so I think the latest update to the vscode extension broke it. (Can't be 100% sure, but I think that's the only thing that is changed).

Your environment

Ubuntu, vscode 1.77.1, HLS 1.10 (also tried with 1.9, same thing), vscode HLS extension of 4/10/2023.

Steps to reproduce

Open any Haskell project, wait for vscode to try and load HLS

Expected behaviour

HLS loads.

Actual behaviour

Error:

2023-04-10 12:00:46.3770000 [client] INFO Starting language server
Invalid option `--stdio'

Include debug information

haskell-language-server-wrapper --debug works just fine; it seems to be the invocation of HLS that goes wrong.

I think the latest update to the vscode extension broke it.

I just ran into exactly the same issue, and reverting to the previous extension version fixes it.

Same here, but downgrading the plugin version (2.2.3 -> 2.2.2) can fix it.

Your environment

  • Arch Linux
  • GHC-9.4.4
  • Stack-2.9.3
  • Cabal-3.10.1.0
  • HLS-1.10.0.0
  • vscode-haskell-2.2.3

Steps to reproduce

Just open a Haskell project, then you can find this info in the log.

Expected behaviour

HLS work normally.

Actual behaviour

The client cannot connect to the HLS.
