Learn Perl the Hard Way

This book is fairly out of date, being almost 9 years old now. I wouldn't recommend it.

A better choice for programmers wanting to learn Perl is chromatic's Modern Perl (http://onyxneon.com/books/modern_perl/).

This looks like a good introduction to the core of Perl programming, however I would recommend "Modern Perl" by Chromatic. It's free (and legal) for the PDF version.

Why do I recommend "Modern Perl" instead? Because it: (1) contains new language features added to Perl in the last 9 years (2) covers how to use Moose for OOP (3) shows how to use new Perl 6 features in Perl 5 (4) clearly explains the right way to do things (5) covers how to write tests (6) demonstrates that the Perl language continues to evolve and is a modern and effective programming language

And in the end, "Modern Perl" shows you how to write maintainable and effective Perl code. Great book, and you can get the PDF for free here: http://onyxneon.com/books/modern_perl/

I have put up exercises from Learn Python the hard way into Learn Javascript the hard way. http://learnjs.info

I downvoted you mostly because I wasn't sure why you were talking about making Python exercises into a Javascript emulator/learner tool when the thread is about Perl.. but then, I wanted to cancel my vote but was unable to.

So why was he talking about making Python exercises into a Javascript emulator/learner tool when the thread is about Perl?

Hmm, very interesting. Looks like these translate alright, but are you running them through node.js?

yes, the backend is node.js and d8

There are two issues in this thread.

First, a confusion: this book has nothing to do with Zed Shaw's Learn X the Hard Way series. (I have no idea if Zed ever heard the title even. He may have come to it - the title - completely independently.) This book predates Zed's series, and has a very different goal. Zed's book, as I understand it, targets novices. The difficulty in the title is that you must do all the exercises and learn from a lot of repetition and trying things on your own (as well as looking up docs, further examples, etc. online). The Downey book, on the other hand, is aimed at people with a programming or CS background who want to learn Perl rapidly. The difficulty is that he moves very fast and assumes you can handle things like a fairly dense Markov text generator by page 26.

Second, a lot of people say (assume?) that the book is out of date because it's from 2003. Actually, for its goal, I think that's wrong. If you are an experienced programmer who wants to rapidly learn Perl's core syntax, I think this is still a good place to start. You certainly might follow it up with Modern Perl or lots of readings in perldoc and perldelta, but the core syntax and features of Perl 5 have not actually changed that much I think. I can't think of any book that covers as much, with as many examples in such a short book. It's also very clearly written.

I came up with the title, started my book, then found the perl book. So this perl book isn't like my books at all and predates them by many years.

"Higher Order Perl" is the book I learned most how to write functional python code.

Yes. I haven't read not a single python book. "Dive into python", "Essential Python", LPHW was boring.

I recommend HOP for every programmer.

Written in 2003!
