haskell-language-server VS xmonad-testing

AFAIK the latest GHC version which the haskell language server (which is what the vs code extension uses) supports is 9.2.2, so not yet, I'd say.

As far as I could see this bug is already reported. It is about stack not being able to handle multi crate project.

I believe you've bumped into this issue: https://github.com/haskell/haskell-language-server/issues/2857

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

All is well and works properly. Now, however, I would like to switch to the git version of Xmonad by using xmonad-testing. For that I cloned the repo, switched both xmonad & xmonad-contrib branches to master and compiled executable. First of all, if I run the executable with `--version`, I get '0.15', that seems to me not correct. Shouldn't it be 0.16, even though it is not released yet? Second, I am not sure whether I need to somehow install the Git versions as libraries to be able to use new features and to get Vim with haskell-language-server recognize the new features. My configuration is in `~/.xmonad`. I think if I copy the config to the directory where the cloned repos are, it (using the new features) will work...

If don't build via the first method and you want to use a project-like structure as in xmonad-testing then yes, you need a cabal file. There is an example file available in the repo.

The other build script I tried is the one from xmonad-testing, modified as follows:

Depending on whether you want to use stack or cabal, there is xmonad-testing, which is a repository that solely exists to show users how to do this! Under build-scripts you can find examples for both stack and cabal (be sure to read the readme for how to use these). If you want to use cabal 3.4 then mind geekosaur's pr for things to work smoothly with the new- style commands which are now the default.

There are some example build scripts that I use that make it super easy.
