The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Haskell is a good, useful, and practical programming language.
Indeed, there is a lot of room for improvements. But I just wanted to acknowledge and thank the work of those involved in HLS which IMHO was a game changer in that regard.

No HLS support for the "recommended" 9.2.5?
Specifically, gchup and HLS are both opensource community efforts. If you want to see HLS work with ghc-9.2.5, you may want to ask https://github.com/haskell/haskell-language-server or, better, provide them a PR that builds HLS with ghc-9.2.5.

dev environment for windows
Sadly ghcup tui is not available on windows, but you can check the available versions with ghcup list. Hls lists the compatible versions of ghc at their github releases. For 1.8.0.0 I went with 9.4.2. To install it and set it to default you have to use the ghcup install ghc 9.4.2 then the ghcup set ghc 9.4.2. Hopefully this will be useful to someone with the same problem.

HLS issues an error for Setup.hs and Spec.hs (using hspec-discover)
Here's an issue I created for it: https://github.com/haskell/haskell-language-server/issues/3348
-
Transform your old and tired Haskell source files in shining Notebooks
The code is executed by HLS, see https://github.com/haskell/haskell-language-server/blob/master/plugins/hls-eval-plugin/README.md and then its markdown/html output is displayed by VS Code.

What is the correct way to compile non-haskell sourcefiles in a cabal project.
As you can see there, Shake is also a good fit for Cabal scripts. And Cabal scripts work better in 3.8. There are still issues loading them with HLS, but hopefully not for long. For this reason, I also have a build.sh which wraps that, allowing the script to be loaded via GHC directly, but I look forward to being able to remove this.
- haskell-language-server 1.8.0.0 released!

[ANNOUNCE] GHC 9.4.1-rc1 is now available
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.
-
Proper editor support?
As far as I could see this bug is already reported. It is about stack not being able to handle multi crate project.

Browser to Haskell Wasm Reactor Module Communication Example
I have a similar example based on Ormolu live. I wonder if there are any libraries being developed to send data back and forth?
-
Format multiline imports in hls (emacs)
You will also need a formatter that uses that style. Brittany for example. The default formattingProvider for HLS is ormolu, which I believe doesn't use this style, so you will have to change this setting.

Advent of Code 2021 day 1
Turns out I prefer Brittany to Ormolu, I edited it so it hopefully looks less verbose all on one line
