Solved #AdventOfCode day 6 part 2 in #Janet with this consice PEG parser and some math. #programming

```janet
{:main (sequence :num-rows :op-row -1)
:num-rows (group (some :num-row))
:num-row (group (sequence (some :num-entry) "\n"))
:num-entry (sequence :blank (some (number :d)) :blank)))
:blank (any (replace " " 0))
:op-row (group (some (sequence :op (opt (some :s)))))
:op (choice (replace "*" :mult) (replace "+" :add))}
```

This time I'm solving #AdventOfCode in #Janet (I'll write about my solutions in my blog in batches) and I'm really pleased by the built-in #PEG parsers. This is how the grammar looks for day 2:

```janet
{:main (sequence :ranges -1)
:ranges (some :range)
:range (group (sequence (number :num) "-" (number :num) (opt ",")))
:num (some :d)}
```

Reading¹ my second short introduction to a programming language book this year "Janet for Mortals" https://janet.guide by @ianthehenry. #Janet (https://janet-lang.org) is a #Clojure like #Lisp that can be interpreted, embedded and compiled, and comes with a large standard library with concurrency and PEG parser support. I must say it is very appealing to me. #programmingLanguages

¹ First one was "Learning Zig" https://www.openmymind.net/learning_zig

This chap's so happy with his Isle of May Gannet poster he wrote a song about it:

The river was deep but I swam it (Gannet)
The future is ours so let's plan it (Gannet)
So please don't tell me to can it (Gannet)
I've one thing to say & that's
Dammit, Gannet, I love you.

Ik vraag dit voor een vriend: in deze rubriek behandelen we een vraag die je niet snel aan je eigen arts of therapeut durft te stellen. Deze week: Janet heeft pas net de 40 jaar aangetikt en ziet tot haar verbijstering kleine, bruine vlekjes op haar...
