8. What about the packages you need?
9. Let’s add a few packages 📦 My list for 🎅 • PHP 8.3 • Python 2.7 (old build script) • ImageMagick 6 (breaking changes in v7 I’m too lazy to look at) • LibreOffice (because, why not?)
10. Let’s add a few packages 📦 Credits: XKCD - https://xkcd.com/1579 My list for 🎅 • PHP 8.3 • Some eerie PHP extension • Python 2.7 (old build script) • ImageMagick v6 (breaking changes in v7 I’m too lazy to look at) • LibreOffice (because, why not?)
11. What’s Nix-t?
12. • Functional package manager • Packages are treated like values + Built in total isolation + No undeclared dependencies + If it works on a machine, it will also work on another machine What’s Nix?
13. • Every package lies in the Nix store • Each package has its files in the Nix store + /nix/store/wyywjj50…-php-8.3.0 + The hash is a unique identifier capturing the package and all its dependencies • Makes it seamless to have several versions of the same package /nix/store
14. • Supported by a functional language + Nix Expressions • 80,000+ packages available /nix/store
15. /nix/store
16. Let’s try again (demo) 📦 My list for 🎅 • PHP 8.3 • Some eerie PHP extension • Python 2.7 (old build script) • ImageMagick v6 (breaking changes in v7 I’m too lazy to look at) • LibreOffice (because, why not?)
