  • Is there some truth to this hyperbole? "Haskell is beautiful and elegant, but unmaintainable and painful"

    It kinda is, but it's a one-time thing and it gives us the ability to map module names to packages by only looking at the index. Plus, the list can be generated: cabal-fmt has an expand feature, and in the future HLS could do that too.

    I know in the past I've had to do things like use a custom `hie.yaml` file, yet, with this merged, and using the latest HLS version recommended by ghcup (1.7), and what doesn't seem to me like an incredibly esoteric build setup -- I have to ask myself: Why isn't this working?

    There is work in progress to integrate the REPL into the HLS (basically what provides IDE functionality to vscode): https://github.com/haskell/haskell-language-server/issues/477

  • This is confusing...

    You can you typed holes with HLS, but sometimes there are performance issues: https://github.com/haskell/haskell-language-server/issues/2315

    The major issue is related to Template Haskell. If you use the current HLS releases, you notice the message "This binary is not built with Template Haskell support". We added this message because the way static binaries work is just not cross-plattform. What might work on ubuntu, doesn't reliably work on other distros. This lead to a number of dynamic linking issues, impossible to understand error messages and many more. See for example this: https://github.com/haskell/haskell-language-server/issues/2659

  • Now that Stackage supports GHC 9.2, is it easy to build ARM executables on macOS?
    1 project | reddit.com/r/haskell | 29 Mar 2022
    The releases page has macOS-9.2.1 but that's Intel, and it has aarch64- but that's GHC 8.
