Wingman not available when using HLS from nix #2869

Closed aVikingTrex closed 9 months ago

aVikingTrex commented 2 years ago

Steps to reproduce

Using Nix for package management using "nix-shell -p ghc haskell-language-server" sets up an environment with: HLS version: 1.6.1.1 GHC version: 9.0.2

Expected behaviour

running "haskell-language-server --list-plugins" should include hls-tactics-plugin

Actual behaviour

hls-tactics-plugin is missing and within any of vim/vscode/emacs, wingman suggestions are not available

Include debug information

--list-plugins returns:

also seem to be hitting this, same hls and ghc versions. i tried using the hls flake directly but i ran into a lot of trouble getting that to work, for some reason.

I think the tactics plugin was working for GHC 9.0 in that version, so it sounds like this is a problem with the nix packaging, and you probably want to take it up with them?

This issue shows up ahead in search results, but it looks like actual discussion about it is taking place in an issue on NixOS, so I'll putting a link here for the benefit of others who wind up here if that's alright: https://github.com/NixOS/nixpkgs/issues/177759
