This week, the new version of Perl was announced. The new version 5.38 is extremely interesting because it introduces classes, which are built-in in the core language. The feature is currently marked as experimental, but nevertheless it was interesting for me to try it out.

Let us ask ChatGPT to find a solution and then correct it to make it more Raku-ish. This task, the machine solved the thing from the first attempt, but you can follow how we managed to make it better and more compact. Most (except one) of the generated code workes without compiler errors, so I will not concentrate on it here.

This week’s task has an interesting solution in Raku. So, here’s the task:
You are given two strings $A and $B. Write a script to check if the given strings are Isomorphic. Print 1 if they are otherwise 0.

Today there’s a chance to demonstrate powerful features of Raku on the solution of Day 18 of this year’s Advent of Code. The task is to print the sum of a list of expressions with +, *, and parentheses, but the precedence of the operations is equal in the first part of the problem, and … Continue reading “Advent of Code 2020 Day 18/25 in the Raku programming language”
In this post, I am telling a story of how updating covid.observer became a bit problematic, and how one of the developers of the Rakudo compiler helped not only to remove the errors but also to speed up the whole system by 2x.

Here is my solution of the first part of Day 12 of this year’s Advent of Code. The point in this solution is that I use multi functions a lot. Well, actually, the whole logic of the program is based on the dispatching rules of the variants of a single multi function. We start with … Continue reading “Advent of Code 2020 Day 12.1/25 in the Raku programming language”
Day 9 of Advent of Code is here and the task is the following. Take a list of numbers and find the first one, which is not the sum of two of the 25 preceding numbers. my $window = 25; my @data = ‘input.txt’.IO.lines.map: *.Int; say @data[($window ..^ @data).first({ @data[$_] != any(@data[$_ – $window ..^ … Continue reading “Advent of Code 2020 Day 9/25 in the Raku programming language”
