scamp-cpu VS advent-of-code

Re the text editor, when I was writing an editor for my homemade CPU I used the one from this tutorial: https://viewsourcecode.org/snaptoken/kilo/index.html - it is 1000 lines of C.

I have diverged a bit from the tutorial because I didn't want syntax highlighting and I really wanted vi-style keybindings. Mine is at https://github.com/jes/scamp-cpu/blob/master/sys/kilo.sl (in my made-up programming language).

I made the computer myself: https://github.com/jes/scamp-cpu/

PROJECT LINK: Solutions GitHub - CPU GitHub - YouTube

In case you're interested, there's more about this project in the github repo: https://github.com/jes/scamp-cpu/ and on my blog: https://incoherency.co.uk/blog/tags/cpu.html

This is really cool and unique. I poked around a bit, and the kernel is vaguely POSIX like, but written in a homegrown language with a compiler written in Perl[1].

Actually, I just found this! That's pretty much what I was looking for. That's what I would have linked if it had been me posting. :) This looks like a really interesting computer project!

JavaScript

Almost walked away from this when caught out by the "empty" space flipping. But stuck with it and managed to make it work without changing my approach too much.

I enjoyed this one, despite all the reading. Felt like a nice change of gear from yesterday's. Using recursion to read sub-packets from the binary string, using a function that returns the value (or version sum in part 1) as well as the length, so I know where to read from for the next sub-packet.

Enjoyed today's one, short and sweet

Mine is similar (but in JS)

Struggled to get my head around the explanation of part 2 today, need more coffee

not the most inspired solution

JS solutions, already settled back into the habit of relying on reduce functions
