@the-mikedavis Maybe pin some «If you are experiencing a crash on 23.05» issue so it is easier to find before posting?

I think there will be a lot of users with nixos-unstable packaging coming here, and diverting them early would reduce amount of issues posted

(thank you!)

[pascalkuthe]

this has alerady been fixed on nix unstable by backporting the patch so its only temporary until people update again

[nilsherzig]

nix shell github:helix-editor/helix # test in your shell 
nix profile install github:helix-editor/helix # use as default hx for your profile

Using the flake works for me. Since the syntax for the language server config changed since 23.05, you will have to change your config file according to: https://github.com/helix-editor/helix/blob/master/book/src/languages.md

dont follow the guide on the website, its for v 23.05 not the current master branch
