directory structure for package sets

[quantenzitrone]

what

A new directory pkgs/sets that contains all package sets instead of having them in the deprecated category hierarchy.

why

We want to get rid of the package categories as directory trees NixOS/rfcs#140 NixOS/rfcs#146.
Package sets don't currently have somewhere to go.

how

I implemented this in #482538, feedback would be appreciated.

As a proof of concept i also move fishPlugins and nushellPlugins to this new structure in #482543.

If this gets accepted, I will also gladly move all other package sets to this new location.

list of package sets

(generated with

nix eval --impure --expr 'let pkgs = import <nixpkgs> {config.allowAliases = false;}; lib = pkgs.lib; in lib.filterAttrs (_: v: (__tryEval v).success && !(lib.isDerivation v) && __isAttrs v && !(lib.isFunction v)) pkgs |> __mapAttrs (_: v: __length (__attrNames v))' --json > result.json
$ jq '. | to_entries | .[] | "\(.value) \(.key)"' result.json -r | sort -n | grep -vE '^(2413[0-2]|0) ' | cut -d' ' -f2 | sort | sed 's/^/- [ ] /g'

related #432625

[SigmaSquadron]

This is quite the endeavour you're undertaking. Should it be discussed in an RFC before we try implementing it? I'm sure the Nixpkgs core team and several dozen contributors have their own ideas about a by-name-like interface for package sets.

[quantenzitrone]

I was about to write one, but i don't think we can do that with versioned package sets like python3*Packages.
Each package set can implement their own by-name like calling structure like I did for fishPackages and nushellPackages in #482543.

[VuiMuich]

Will this still allow the mergebot to work simply by approval by the package mainteiners?

[SigmaSquadron]

This work isn't necessarily related to the merge bot. Once the new sets are implemented, we can look into making new rules for it.

[VuiMuich]

I see, thanks for the clarification.

So in the longrun this might be the desired route, but to improve the situation with nushell plugins lagging behind it might be worth to take the intermediate step to move them (alongside the nushell package itself) to pkgs/by-name right now.

[quantenzitrone]

Ok i think I'm going to write an rfc presenting different ideas to get more opinions.
