NixOS itself by default isn't fully declarative anyways, nix-env for example is imperative and very comparable to flatpak regarding applications.

I welcome the efforts to move away from all imperative bits in NixOS though. My point was rather not to dismiss an article on NixOS for mentioning flatpaks.

    Flakes takes care of a lot of the imperative bits, but some people are wary of them since they're marked experimental.

    I don't think flakes can do much more declarative than "legacy" nix, rather they increase reproducibility and purity. Also their tooling doesn't offer imperative stuff by default, but I'm not sure they cover use cases previously solved imperatively. E.g. I don't think you can install user software through a flake. Sure you can create shells with software available, but that is also possible without flakes.

    Maybe my understanding here is wrong though.

    They cover a few things -- most notably they replace channels, which are imperative.

    Unless I'm way off, you can also install user software through flakes if you add them as inputs. That's what I'm doing with Musnix.

    You can also pull a repo and 'nix run .#software' from the command-line, without entering a shell. That's how I'm using NixifiedAI.

    True. I never considered channels imperative, but rather a purity issue. But I guess this is a matter of perspective.

    I don't know about this, but that doesn't mean anything.

    True, though this by default only runs the default binary, and you're probably in a shell anyways, so it doesn't save that much. Also that output is, to my knowledge, not protected by garbage collection. But my knowledge of any imperative stuff is minimal, so I don't know if that's the case there.

    Why doesn't it mean anything? You add the flake as an input (declarative) and then add the software to your config (also declarative).

    I'm not arguing that it's better, or saves time, just that it takes things that were done imperatively, and makes them declarative.
