Hands-On Perl 6
Jeffrey Goff offers an introduction to Perl 6, a powerful new language combining the pedigree of Perl 5 with a brand new metaprogramming system, built-in concurrency, and software-definable grammars, among many other features.
Starting from one-liners like “Hello, world!” Jeffrey explores all of the programming styles that Perl 6 has on offer, from basic procedural programming to object-oriented style, aspect-oriented, functional programming, and even logic programming. From the basics of sigils (the $ signs that so many scratch their heads over) and context, you’ll banish lazy evaluation, march through infinite lists, and stalk the wild hyperoperators. Jeffrey introduces simple variables and user I/O by way of a guessing game.
After discussing variables and how they’re affected by the context they’re used in, Jeffrey delves into what’s traditionally been the core of Perl: regular expressions. Starting with some simple matching tasks, Jeffrey explains how to parse what even Perl 5 regular expressions can’t tackle with a custom grammar. This custom grammar helps teach you object orientation and aspect-oriented programming. You’ll then build an interpreter with the help of some hyperoperators and use Perl 6 roles to construct both an interpreter and assembler inside Perl 6. J
Jeffrey also discusses the community surrounding the language, how to find other programmers, and how to find and share your Perl 6 code. You’ll walk out of the tutorial with a solid grasp of the fundamentals of Perl 6 and an exposure to what lies beyond the world of basic scripting.
- Knowledge of basic procedural programming (Object-oriented knowledge will be useful but is not required.)
Materials or downloads needed in advance
- A laptop with Rakudo Perl 6 installed (Docker users can run “docker pull rakudo-star” to get the latest version.)
