scamp-cpu VS adventofcode.sh

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!

I have completed years 2015 and 2020 in bash. Gave up halfway through last year, might do that one day. https://github.com/einarjon/adventofcode.sh

Python3 is about 25% faster than Python2, with the exact same code. Pypy3 was somewhere in between. https://github.com/einarjon/adventofcode.sh/blob/main/2015/04.sh

Mine is on github too. I think that my worst abuse of grep is this: https://github.com/einarjon/adventofcode.sh/blob/main/19.sh Before the cleanup my part2 regex was around 6-7K chars.

My final script is in my repo, but an earlier commit has this brute force version. https://github.com/einarjon/adventofcode.sh in the 2021 folder.

Day 1 was 10 LOC, each day is adding about 10 LOC, so now I'm at 40. I don't like where this is heading. https://github.com/einarjon/adventofcode.sh/blob/main/2021/04.sh Small mistake in Part 2 so it starts the bingo from the beginning, but the first numbers are crossed out. Doesn't affect the result.

My solution this year was almost exactly like the one __abigail__ posted. I based it on last year's code for day 12. There are 50 days worth of bash solutions in that repo if you're interested. Some contain Voodoo, but it's mostly readable - I hope...

I linked to the code. Here it is again. Might be slower in git bash, but works. https://github.com/einarjon/adventofcode.sh/blob/main/13.sh
