Autocomplete/ Grammar not working on NixOS

[dankeyy]

I get no autocomplete at all, as I gather what i needed to do is hx --grammar fetch, but

[nix-shell:~/testing]$ hx --grammar fetch
Fetching 107 grammars
107 grammars failed to fetch
        Failure 0/107: Could not create grammar directory "/nix/store/fj5a20w0sadd9d52y0z6d692nqjl955s-helix-22.08.1/lib/runtime/grammars/sources/elixir"
...

Because of course in NixOS the store is read-only.
Any suggestions?
Spinning up a FHSUserEnv for this seems a little silly

Ideally I'd like helix to rely on local files only

To get autocomplete you need to install language servers specific to your language. The grammar fetching is something you don't need to do on a packaged build.

Of course I have the language server installed (say rust-analyzer, hx --health confirms it), autocomplete still doesn't show up

For grammars not building because of the immutable store: #3346

Autocomplete doesn't involve the tree-sitter grammars though.

What does the log file say when you are editing a project in a language like rust where you have the language server installed? https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file (hx -v)

Ok I believe it was my wrongdoing with a cargo.toml
Anyway all works now so I'm closing this
Thanks guys
