haskell-language-server VS hie-bios

I previously used IntelliJ IDEA on Linux for over eight years, so I can sympathize with your struggles. [1] Recently I started using OSX because my Thinkpad finally died and I could not find another laptop I liked. So far, it's been pretty bumpy, although I have noticed that some things have improved such as fonts and build times. The downside is that very few things currently work on aarch64 right now, so I somewhat regret making the switch this early. I recently started writing some Haskell, which was a pain to setup on my local machine but now that GHCi and Stack support it [2], I think it's getting stable. Hopefully native libraries will improve their support, because despite the minor speedups (faster JVM), overall it's been a productivity-killer. Very, very few native libraries offer aarch64 builds right now.

The tooling story has gotten much better with haskell-language-server unifying the formerly fragmented landscape. I'd highly recommend installing it.

Searching for "memory" among the open issues on haskell-language-server, yields quite a few results. From a quick glance, it seems to depend on the project, as specific projects seem to make the language server behave/leak quite bad.

If you have haskell-language-server installed it can also tell you what to import and even automatically import it for you.

- [#2365](https://github.com/haskell/haskell-language-server/issue/2365): hs-boot files not handled correctly, discovered in the ghc codebase and fixed with [#2377](https://github.com/haskell/haskell-language-server/pull/2377)

Cause they still cant be built with ghc-9.0.1, see: https://github.com/haskell/haskell-language-server/issues/297 , and https://github.com/haskell/haskell-language-server/pull/2202 for tactics

Hey! It sounds like hlint is working but not HLS, which is why you just get suggestions but not the errors. A bit similar to what I just ran into a couple of days ago. Could you check the logs from running haskell-language-server at the project's root directory, and see if it's similar with the ones I posted here?

Look here: hie-bios (its the library used by haskell-language-server to get to know your project better, iirc).

Yeah the same happened to me with previous versions of the Haskell IDE Engine that used Stack, so I ended up with several snapshots under \~/.stack that took a lot of space. Nowadays I just install HLS, Cabal and a single HLS-supported GHC with ghcup. It's a huge difference. I think there is a Windows-supported equivalent of ghcup, but I have not used it. If you also have Stack installed, remember that you can place a [`hie.yaml`](https://github.com/mpickering/hie-bios#explicit-configuration) file in your project root that can [force HLS to use cabal](https://github.com/mpickering/hie-bios#cabal) instead of stack in your project (this was needed last time I checked, complex configurations would need tuning this file a bit, though).

You can provide an alternative stack.yaml to HLS, with the specific configuration for the ide, although you have to write down an explicit hie.yaml file, take a look to https://github.com/mpickering/hie-bios#stack

Please consider testing dev builds with the WIP new vgs-bios feature, inspired by the amazing hie-bios. It reads your project hie.yaml and supports multi-component/multi-package projects.
