Description
Hello,
first of all thanks for bringing Nix support in Zed.
I was initially trying to use nil as a language server but the error was [WARN] no language server found matching 'nil'.
Looking closely I realized that the actual problem may be:
[ERROR] failed to load wasm extension nix
Caused by:
0: error parsing wasm extension
1: unexpected end-of-file (at offset 0x366c1)
The no language server found error happens before and after these lines.
I'm on NixOS (nixpkgs-unstable) and this is the piece of configuration that handles Zed (via Home Manager):
{
lib,
config,
pkgs,
...
}:
let
cfg = config.components.dev.IDEs.zed;
in
{
options.components.dev.IDEs.zed.enable = lib.mkEnableOption "Zed editor";
config = lib.mkIf cfg.enable {
home.packages = [ pkgs.nil ];
programs.zed-editor = {
enable = true;
extensions = [

What seems most significant is:
[ERROR] failed to load wasm extension nix
Caused by:
0: error parsing wasm extension
1: unexpected end-of-file (at offset 0x366c1)
which maybe causes the LSP issues?
Right now I get syntax highlighting but nothing more. Am I misconfiguring anything or could this be a bug?
Thank you
