Perl: A Beginner's Guide in the AI Era

Perl has a reputation for being write-only — powerful, but impossible to read once you've written it. That reputation is outdated, and this book teaches the disciplined, modern way to learn it instead.

*Perl: A Beginner's Guide in the AI Era* takes you from a blank terminal to four working programs — a log analyzer, a CSV-driven contact manager, a web API client, and a capstone project you build largely on your own. Along the way you'll learn scalars, arrays, and hashes; regular expressions (still one of Perl's greatest strengths); subroutines and scope; references and nested data structures; file handling; and how to read and untangle other people's messy legacy Perl.

What sets this book apart is how directly it treats AI as part of the modern learning process. Every chapter includes an AI Sidekick — a specific, well-crafted prompt for verifying your understanding with an AI assistant like Claude or ChatGPT, rather than a vague ask AI if you're stuck. You'll also learn a real, practical workflow for reviewing AI-generated Perl code, since AI models frequently produce outdated, pre-strict Perl if you don't know what to check for.

Written in a friendly, conversational tone — like a patient senior developer explaining things over coffee — this book assumes no prior Perl experience and builds your confidence chapter by chapter through hands-on practice, mini-challenges, and real projects, not just syntax reference.

By the end, you won't just know Perl syntax. You'll know how to build with it, debug it, read someone else's version of it, and use AI as a genuine collaborator rather than a crutch.
