Minor cleanup of flake.nix

[Rexcrazy804]

used with pkgs; to simplify statements referring to it in the scope of mkshell. Restructured input declaration to follow the typical structure.

I am unsure whether I should mark this with doc: or not, sorry

If permitted, I'd like to add a shell hook that executes the default shell using the $SHELL env var so running nix develop will drop you into whatever shell you are using instead of defaulting to bash. I suppose that could be another pr?

I disagree with this, perhaps check out direnv if you haven't already?

@itslychee I have specified the three major systems, do you reckon there's anything else to add?

Don't forget to change buildInputs to packages, and after that I'd squash all the commits into one commit to keep the history clean.

Also since eachDefaultSystem is used currently, it's best to add "x86_64-linux" to the platform list to keep it backwards compatible as eachDefaultSystem used 4 platforms as described here

[Rexcrazy804]

Could you clarify that a bit further? The platforms list does contain "x86_64-linux" but it has come to my attention that "x86_64-darwin" is not included in the list, I suppose that is the one I should add.

Oops yeah that's the one, something possessed me to write linux instead 😭

why remove the pkgs prefix ? it's just churn . If anything it makes perf and linter work harder please revert

[teto]

I get that one would prefer to remove the dependency to flake-utils but what's the point if you have to replace allDefaultSystems by actually typing the defaults yourself ? The handling of system is one of the controversial point of flakes and nothing in this PR is objectively better so it's just churn. I would just merge an update to the lockfile to get a more recent version of the dependencies.

The point here is to remove a dependency that can be easily replaced with functions of nixpkgs' library, and to remove noise from the lockfile. It also makes it more clear how outputs are defined instead of having flake-utils magically insert system between a nested attrset that may not even be desirable.

The handling of system is one of the controversial point of flakes and nothing in this PR is objectively better so it's just churn.

How is eachDefaultSystem not churn then? How is removing an input that's not even needed and replacing the functionality with a genAttrs wrapper while retaining the same behavior with the previous solution not a better approach, as it also gets rid of the rec keyword that's not even used anywhere?
