The no obvious reason point is.

@withoutK Thanks for helping - the problem seems to be due to haskell/vscode-haskell#471 and everything works fine on the latest v1.7.1. It is weird though when the HLS crashes it did not display Invalid argument `'.

alissa-tung commented 3 years ago

I am more confused with how it failed and how it works now, afaic it will remain a mystery to me.

(to explain a bit why) According to the log and if it is triggered by the following.

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

  • It is merely produced by the server side of the Haskell language server, it even does not invoke a client (namely, vscode-hls or lsp-haskell).
  • the error messages pointed out the failed file and corresponding reason.

Hence I was confused by stating that was caused by an LSP client. (But that's not the main reason, for I had done some experiments with git checkout). Anyway, it is always to test it yourself locally and it would be better to do it for Stack is rather delicate. It would be better to keep client plugins up-to-date for it was pushed to my device yesterday earlier than 19:00 UTC+8.

Anyway, my conclusion can just lead to misleading for I do not write Haskell myself, neither use the Stack, HLS, etc.

I remembered it worked on my older machine where I used the short cradle

cradle:
  stack:

on an older version even with the error in Setup.hs present so I think that is unlikely the reason.
