haskell-language-server VS vscode-haskell

The advent of language server protocol made possible the creation of HLS (Haskell Language Server), and there are plugins for many editors, such as vscode-haskell, that allow you to have auto-complete, auto-import, and automatic function signatures—also available to your editor of choice. The whole feedback loop of editing, compiling, and running is greatly improved.

HLS 2.3.0.0 is currently broken on Windows.

The Haskell community has been focusing on tooling and IDE support in the last several years. Haskell-Language-Server is a huge improvment, so the experience is probably much better than you remember, but it'll still be a while before it catches up with Rust.

static-ls is a low memory language server for Haskell that serves as an alternative to (hls)[https://github.com/haskell/haskell-language-server] with less functionality by using statically generated information. It is intended for (Highly recommend hls instead if you aren't having these issues):

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.)

Have you tried installing Haskell with https://www.haskell.org/ghcup? After installing it vscode with the https://github.com/haskell/vscode-haskell Haskell extension should work out of the box.

I reported the issue here, let's see what happens.

The release never made it through: https://github.com/haskell/vscode-haskell/actions/runs/2823440618

But generally, haskell-language-server should give you a proper IDE instead: https://github.com/haskell/vscode-haskell

Re-enable upgrade functionality for all configurations wrt MR #250 and VSCode haskell issue #601

Since this is going to be a very much breaking release, please expect bugs and rough edges we have to iron out! Please report all issues you encounter at the vscode-haskell issue tracker or reply to this post :) We ask you for your feedback, especially documentation wise: What do you think needs more explanations and what feature is harder than necessary to use or debug?

Same. Looks like someone's just finally opened a bug report: https://github.com/haskell/vscode-haskell/issues/471
