Yeah the LSP support is next, my goal is to implement the language server in the fuse itself. At the moment there’s a simple formatter implementation fusefmt: https://github.com/fuselang/fuse/blob/master/examples/fusefm..., you can compile it with fuse and hook-it with your editor.

For example I’ve this config in helix:
