Hi, I was wondering if there is a good set up for haskell programming in vim that anyone may want to share and provide a pictures

Thanks :wink:

I’m also interested if anyone has a good setup with HLS and vim to share.

I’m mainly just using CoC. I think it’s decent and it has full LSP support but it has a lot of options that I have not explored yet. I’m also using ctrlp for finding files.

This is my neoVim setup, with HLS and native neoVim LSP.
I haven’t uploaded pictures yet though.

my dotfiles

Feel free to ask me questions!

Their is a thread on using nix to setup hls.

I’m also using the Coc plugin to run HLS. However it feels like I’m missing out on some of the features… I’ve set up bindings for coc-codeaction-line and jumping between errors. Any other recommended config?

I have basically just copied the example config from that github page. It has a bunch of comments explaining what all of it does.

In addition to what others have said, I’ve also got a ton of value out of integrating linters like HLint using a linting engine like ALE.

Once installed, it’s just a case of adding something like let g:ale_linters = {'haskell': ['hlint']} to your Vim config.

Binding coc-codelens-action lets you use the eval plugin and some other completion features.

It’s important to note that you need to use coc-codeaction-selected on a visually selected type hole to get Wingman (isovector’s excellent plugin for generating code from types) code actions to show up. They won’t show up for coc-codeaction. This tripped me up for a while
