Smarter nix_flake_fmt condition?

[mightyiam]

Hey, @jfly and anyone else interested. I was using nix_flake_fmt for a while in async mode and it was mostly very helpful. But as soon as I tried it in sync mode within a project that does have a flake.nix but that does not provide a formatter, it seemed like I was hitting the timeout consistently. Could that be the case?

This is not how it's supposed to work. I think it's a bug here:

none-ls.nvim/lua/null-ls/builtins/formatting/nix_flake_fmt.lua

Line 314 in 01f8e62

return false

. We're returning false and never calling the _done callback. Makes sense that that would cause a timeout.

Just sent in a PR fixing this: #350
