          If anyone else comes across this thread, I was able to get a `haskell-language-server` with the latest `reflex-platform` (1.1.1.0) (uses ghc 8.10.7 ) by doing the steps mentioned here (btw I'm not using obelisk):

https://discourse.haskell.org/t/haskell-language-server-ghc-version-could-not-be-determined/5856/10

These are the steps in the link:

• checkout haskell-language-server (I used the 1.8-release branch since that's the last version for ghc 8.10.7)
• go into your reflex platform project nix-shell
• cd into haskell language-server directory
• run cabal install
• configure your ide LSP settings to find the hls server executable at $HOME/.cabal/bin/haskell-language-server (the wrapper doesn’t work)

I think reflex-platform should provide an option to install hls. Nix could probably automate the cabal install manual step right?
