I'm a relatively new user and I've successfully set up Hyprland with home manager. I wanted to try out Niri though but it's a bit more confusing for me. What's the point of that repo? Does the Niri that's in nixpkgs not work with home manager? Is that repo, and that repo alone, expected if you're using home manager and want to manage Niri with it?
Thanks!
That's the master branch and, as you noticed, it was added after the 26.05 release (that's why I didn't find it when looking through home manager options). So it's likely that after that module is finished and released, niri-flake won't be needed.
(To be pedantic, niri-flake was never "needed", it just provides useful options/functions so you don't have to write them yourself. And it could be the case that it will still provide some things that the home manager module won't, though I can't think of any examples)
