Welcome to my Advent Calendar 2019. Last year, I was publishing daily articles about one-liners in Raku. This year, I decided to spend time on filling the gap in other areas and try as many other languages as possible. This series of publications transformed into my book ‘A Language a Day’, which you can get … Continue reading “‘A Language a Day’ — Advent Calendar 2019”
In the previous post, we were talking about the constexpr keyword in modern C++. It was added to the C++ 11 standard, but in C++ 14, it got a very nice addition. In particular, you can do more in constexpr functions now. Consider the following program that wants to pre-compute a factorial of 5. #include <iostream> … Continue reading “constexpr in C++ 11 and C++ 14”
There is a new version of this book. If you want to get an electronic copy or a paperback, see Using Raku for more details. 100 Programming Challenges Solved with the Perl 6 Programming Language This book is a collection of different programming challenges and solutions in Perl 6.

The Perl 6 One-Liner Advent Calendar 2018 is over! Let’s make a quick overview of what we have covered so far. There were a few themes covered. First, some one-liners from the Perl 6 Calendar 2019 were explained in more detail. We looked at how to generate random passwords and random integers, how to print … Continue reading “🎄 26/25.

Welcome to Day 11 of the Perl 6 One-Liner Advent Calendar! Today, the calendar post is totally devoted to the solution of problem 34 of Project Euler. Once again, let me warn you to pause reading if you want to find your own solution prior to seeing mine. So, the task is to find the … Continue reading “🎄 11/25. Solving the Problem 34 in Perl 6”
Welcome to Day 10 of the Perl 6 One-Liner Advent Calendar! Today, there will be three one-liners instead of a regular one. Our today’s guest is a reduction construction with a pair of square brackets. When they do not surround an array index, they work in a completely different field. Example 1 The most classical … Continue reading “🎄 10/25. Reduction operator in Perl 6”
Reduction operators are one of the many attractive features of Perl 6. A classical example is calculating factorial: say [*] 1..5; # 120 It is remarkable that in the AST output (generated with the –target=ast command-line option) you do not see any cycles. There is the METAOP_REDUCE_LEFT call, and obviously, the rest is hidden on the deeper … Continue reading “🔬52. An attempt to understand how [*] works in Perl 6”
