About Raku

say my $candidates = all
  «Alphabet subdermatoglyphic
  ‘Emily Jung Schwartzkopf’».pick: 2;

say “All isograms? {.so ?? ‘✔’ !! ‘❌’}”
  given is-isogram($candidates);

sub is-isogram (Str $_ --> Bool) {
  .uc.comb(/<:L>/).Bag ⊆ 'A'..'Z' }

Raku (formerly known as Perl 6) is a clean, modern, multi-paradigm language; it offers procedural, object-oriented AND functional programming methodologies. It is a supremely flexible language, adapting to your style of programming, whether that be quick one­liners for sysadmins, scripts to manage a database import, or the full stack of modules necessary to realise an entire website.

Raku enhances Perl’s long­term appeal with a proper object system including roles, threading and multi­method dispatch. It has spent a long time coming to fruition and has learned from other programming languages, building on their success and learning from the issues of the past. We believe Raku is a language that will last for decades as it has been conceived to adapt to future trends and is flexible in its usage with other languages.

Raku learns from other languages. For instance: taking threading from Java (simplified to a handful of methods); Foreign-function interfaces from Lisp make accessing libraries as simple as one line of code. Regular expressions are now turned up to 11 with the introduction of Parser Expression Grammars, which let you tackle huge parsing tasks. Strictures and warnings are now automatic, cutting out huge swathes of potential errors.

Raku’s mottos remain the same as Perl: “Perl is different. In a nutshell, Perl is designed to make the easy jobs easy, without making the hard jobs impossible.” and “There Is More Than One Way To Do It”. Now with even more -Ofun (optimized for fun) added.

Exercism is a great website

Exercism is a great website where I was able to have some very interesting challenges.

Relaxed. Encouraging. Supportive.

A Perl programmer for several decades, I am now promoting Perl 6 for the same reason. It's a full toolkit for solving almost any problem. I've learned quite a few things, let's learn some more together!

My first adventure in coding was creating userscripts by trial and error (many errors...). Somewhere down the line I accidentally found myself employed in my first coding role as a Perl developer, after attempting pair programming in Haskell.

Get started with the Raku track. As with everything on Exercism, it's 100% free!
