As this is not intending to be compatible with nix profile list (and rightfully so), maybe it could replace it instead?
This is based on an experiment I did today, and I quite like the result:
{
description = "Default packages to install into user environment";
inputs = {
flakey-profile.url = "github:lf-/flakey-profile";
nixpkgs.url = "github:NixOS/nixpkgs/3281bec7174f679eabf584591e75979a258d8c40";
flake-utils.url = "github:numtide/flake-utils";
};
outputs = { self, flakey-profile, nixpkgs, flake-utils }@inputs:
(flake-utils.lib.eachDefaultSystem (system:
let
pkgs = nixpkgs.legacyPackages.${system};
in
{
packages = {
profile = flakey-profile.lib.mkProfile
{
inherit pkgs;
paths = with pkgs; [
coreutils
gnused
];
pinned = {
nixpkgs = toString nixpkgs;
};
} // (
let
empty-profile = pkgs.runCommand "empty" { } "mkdir -p $out";
in
{
history =
pkgs.writeShellScriptBin "history" ''
# Workaround for https://github.com/NixOS/nix/issues/1807
ln -snf ${empty-profile} "$(dirname $(readlink ~/.nix-profile))/profile-0-link"
nix profile diff-closures | grep -v "^empty:"
'';
list = pkgs.writeShellScriptBin "list" ''
nix store diff-closures ${empty-profile} ~/.nix-profile | grep -v "^empty:"
'';
}
);
};
})
)
;
}After running nix run .#profile.switch, you can easily see which packages are installed:
$ nix run .#profile.list
coreutils: ∅ → 9.5, +1533.7 KiB
flake: ∅ → ε, +27.7 KiB
gmp-with-cxx: ∅ → 6.3.0, +555.1 KiB
gnused: ∅ → 4.9, +246.8 KiB
libcxx: ∅ → 16.0.6, +3161.2 KiB
And, you can also see a history after adding and removing packages:
nix run .#profile.history

Integrating this would require the addition of a profile argument, as it's not guaranteed that ~/.nix-profile points to the profile you're interested in.
I'd be happy to write a PR, but I'm uncertain if this is desirable at all? Maybe you consider it feature creep?
Additionally, the reliance on two currently unstable nix commands is probably not great. An alternative would be to use nvd instead, which would also produce nicer output, but that could be considered bloat, as it adds python3 as a dependency.
Let me know what you think.
