I implemented UUIDv7 in Common Lisp for fun. The implementation isn't very efficient since I decided to work with bit arrays before converting to bytes to deal with things like 48 bit integers. Plus some other dirty hacks but 🤷‍♂️

Jk fixed the bug in the bit-shifting version I had earlier. Just needed to walk away for a second.

Because I don't know Common Lisp well and chose to work with bit vectors some things are gross e.g. converting the bit vector #(1 1 1 1 1 1 1 1) to the integer 255 meant first converting to the string "11111111" and then parsing that into an integer which... 😅

I’ve used it on and off for tiny things over the years, including using StumpWM briefly. Big fan of Lisps by way of Emacs and some Clojure. Also really like Scheme and have a bunch of projects in the backlog 🤓

I’m a PL nerd so I’ve sipped a lot of different flavors of koolaid over the years.

What brought you to Common Lisp?
