  • haskell-language-server

    Official haskell ide support via language server (LSP). Successor of ghcide & haskell-ide-engine.

    Project mention: [Well-Typed] Multiple Component support for cabal repl | reddit.com/r/haskell | 2023-03-17

    I think the corresponding HLS PR is https://github.com/haskell/haskell-language-server/pull/3462, so it isn't landed yet but hopefully can be part of a HLS release before too long. (I'm not sure if it will make it in to the very next release because we're due one out to support GHC 9.6.1 pretty soon.)

    🕵️ Haskell STatic ANalyser (by kowainik)

    Project mention: Comparing strict and lazy | reddit.com/r/haskell | 2022-05-21

    That sounds very interesting. Maybe it would not be very hard to implement a prototype of such a system with Stan?

  • gi-atk

    Generate Haskell bindings for GObject-Introspection capable libraries

    Project mention: build the package gi-harfbuzz on Archlinux | reddit.com/r/haskellquestions | 2023-02-24

    Another thing you can try is the ghc-wpc project which has an interpreter which supports breakpoints, though you may need to hack little a bit to achieve your goals.
