Supac is a declarative package manager written in Rust fully scriptable in nushell. It's meant to make it easy to use the native package managers in existing distros without going through the associated headaches of using Nix, while maintaining the ergonomics of structured data in nushell.

Currently supported backends are:

Archlinux and derivatives
flatpak
cargo/cargo-binstall
uvx (packages only for now)
rustup toolchains

I daily drive it, and it works well. Feel free to give it a try!

From what I understand (I've never used mise), mise is meant for programming environments and tools. Supac works with your distribution's package manager to manage all your system packages and also language toolchains like rustup and uvx (uvx backend doesn't manage toolchains yet, it's being developed though).

What it doesn't manage are programming environments, basically, you cannot use it to spawn something like a nix devshell. Hope it makes sense. This is more meant to be along the lines of something like nix, but friendlier and easier.
