Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Supac - a declarative package manager written in Rust, scriptable in nushell

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!

Ah yes, I came across this when someone else pointed it out as well. The project looks neat, ngl. supac also shares some goals along these lines, but dcli looks more mature. I still prefer supac (it's my project duh) because supac allows you to script in nushell, which lets you do interactive development (if you use nushell as your shell, which you absolutely should!). I also don't prefer something like YAML for config, but since it's extensible with lua, I guess it makes sense to go with a config language as well. I do think the end goals are different, I try to orient supac to be a nix alternative but with integrated package management across different package managers. Also, supac is simpler in principle because a lot of the complexity is shifted to accompanying libs in nushell (such as systemd unit integration).

Not to mention, with a couple of lines of nushell code you can probably import all your yaml configs from dcli into supac :)
