use hls with jupyterlab-lsp (warning No plugin enabled)

[GTrunSec]

I was trying to use the hls --lsp server for Haskell kernel with jupyterlab-lsp.

I got the issue output as follows, Does anyone know how to enable that plugin?

             , ghcide-code-actions-imports-exports

It seems the hls settings doesn't work on the jupyterlab-lsp https://github.com/jupyter-lsp/jupyterlab-lsp#configuring-the-servers

In HLS, each plugin specifies the file extensions it knows how to handle.
The ghcide plugin, which takes care of .hs, .lhs, etc... files, probably doesn't want to handle the jupyter notebook extension. That looks like an unintentional behaviour change introduced by #2945.

Did HLS ever work for jupyter notebooks? Since jupyter requires a custom ghc version to compile successfully, seems like this would never have worked, unless you maintain a fork of HLS?

Yeh, jupyter-lsp/jupyterlab-lsp#313

@fendor thanks, I got the same answer from other people. I should be patient for https://github.com/codedownio/haskell-notebook-language-server.
