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!
