The Pearls of Raku, Issue 5: the where clause

In this issue, I will be looking at the three use cases with the where clause. All the examples refer to the MAIN function, but the content is applicable to any other function.

The Pearls of Raku, Issue 4: unit sub MAIN and command line, round and precision

Welcome to the next issues if The Pearls of Raku! Today, some interesting findings that I discovered while reviewing the previous weeks of The Perl Weekly Challenge and today when I added a new graph to The Coronavirus Observer.

🎥 Raku challenge review week 70

In this article, my review of the Raku solutions to the Weekly Challenge 70. The tasks are: 1) Character swapping, and 2) Generating Gray code. As a regular part of the review, there are two video covering all solutions that were sent by the participants.

🎥 Raku challenge review week 67

My review of the solutions in the Raku programming language of the tasks from Week 67 of the Weekly Challenge. The task 1 is to generate numeric combinations. The task 2 is to work with the letters on a phone keypad.

The Pearls of Raku, Issue 3: tr, TR, and StrDistance

How do tr, TR string replacements work in Raku. What is a StrDistance type? What happens when you print such objects with ‘put’ and ‘say’?

🎥 The Pearls of Raku, Issue 1

Let me demonstrate a few interesting things that I found by looking at the Raku solutions of last week’s Perl Weekly Challenge 1. All of them are notable as they reflect how differently people think, how unexpectedly they approach the same problems, and how big Raku is. So big that you forget or never meet some of its corners. In this issue: method operatos, $*USAGE, and :skip-empty.

Raku challenge Week 70, issue 1

Here is a program in Raku to solve the task 1 of the weekly challenge. An interesting thing here is a reminder of how you swap the two elements of an array.

Gray code in Raku

Let us create a one-liner to generate the sequence of the so-called Gray code in the Raku programming language. This code is essentially a method of binary coding so that for each of the following integer number, you only change a single bit.
