Expose an overlay in `flake.nix`

[leungbk]

It would be nice if the flake.nix exposed an overlay defining the bleeding-edge helix. This would permit clean composition into a personal configuration without otherwise changing existing Helix-related configuration.

Example: https://github.com/oxalica/nil/commit/4c77fa90ef238f81c2c801db66b1d56140551ecc

i am not quite sure if i understand it correct, but: by adding github.com:helix-editor/helix/master as a flake input, you could essentially overwrite the package in the home-manager options for helix like so:

{ helix-master, pkgs, ... }:

programs.helix = {
	enable = true;
	package = helix-master.packages."x86_64-linux".default;
	# your config here: ...
};

at least that's how i do it (well sort of) i have a personal forked branch which adds some open pull requests. :)

This may or may not be a proper way of doing it, but at least by doing that you have access to the 'bleeding edge' :)

Your way is good too, it's just that if my proposed change is implemented, the end user has an even easier time of it, by simply adding the overlay into their flake.nix without having to additionally drill the helix flake input into their home.nix.

Couldn't you just trivially define your own overlay?

From my config:

final: prev: { inherit (flakes.helix.packages.${system}) helix; }
