awk VS advent-of-code

Awk now supports a `--csv` flag for processing csv's. https://github.com/onetrueawk/awk/blob/master/README.md

Right, "the one true awk" corresponds to a book written in 1988, very explicity. https://github.com/onetrueawk/awk

You were the one that that said POSIX awk to begin with, I was using your terms.

As far as shitting on the GMU tools, I don't think I've seen someone do that for over 20 years.

This is not a productive conversation. You can live life however you want

I also wrote a small program to benchmark and check the solutions across different Awk implementations (see the image). I use the macos system awk (which is pretty close to https://github.com/onetrueawk/awk if I'm not mistaken) as a reference (the first column), so all solutions had to work with that.

A simpler Yacc grammar is awk/awkgram.y.

Neat, this is now the third year I'm using awk and still learning new tricks. (I'm using awk as the reference, so I don't use gnu extensions.)

I did this in nawk, which doesn't support extended regular expressions. If instead you're using gawk, which does, check out \b for word boundaries in extended regular expressions. The [^a-z][a-z] approach you showed consumes the prior character.

This is dumb as fuck. Brian Kernighan of K&R (The C Programming Language) is 80 and he’s still more intelligent than any of you retards. Mf just submitted a patch to awk a couple months ago https://github.com/onetrueawk/awk

[LANGUAGE: Python 3] 153/75 Raw solution

One could instead count |F7 (that's what I do in my refactored solution), but counting all the bends would miscount the vertical segments (FJ would end up canceling itself out).

That sounds like what I suggested here, actually. I don't have anything in my library with quite the right API yet, but I already have most of what you describe coded out. (It looks like I whipped it up for 2017 Day 13.)

It doesn't, but you can use a separate list, wrapper classes, and deque.index to find where the values live. I may be biased but I think that my solution (ultimately using deque) isn't as complex as a custom linked list.

Part 2 assumes you did part 1 properly. I did not! I'm pretty sure that the intended solution is to do a sort of reverse search (have a target number of geodes and work backwards to see if that's possible to achieve) but I was just not having success coming up with a way to do that. It's probably going to be blindingly obvious once I figure it out, but that might be an exercise for tomorrow.
