    Look here: hie-bios (its the library used by haskell-language-server to get to know your project better, iirc).
  • Portable Haskell with VS Code?

    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).
  • Is almost everyone using VS Code now for Haskell?

    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.
