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. 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.
