Cooking is perhaps the humblest of the arts; but to me humility is a strength, not a weakness. Great artists have always had to serve their artistic medium - great cooks just do so literally.

And the more humble the medium, the more humble the artist must be in order to lift the medium beyond the mundane. Food and language are both humble media, consisting as they do of an overwhelming profusion of seemingly unrelated and unruly ingredients. And yet, in the hands of someone with a bit of creativity and discipline, things like potatoes, pasta, and Perl are the basis of works of art that "hit the spot" in a most satisfying way, not merely getting the job done, but doing so in a way that makes your journey through life a little more pleasant.

Cooking is also one of the oldest of the arts.

Some modern artists would have you believe that so-called ephemeral art is a recent invention, but cooking has always been an ephemeral art. We can try to preserve our art, make it last a little longer, but even the food we bury with our pharoahs gets dug up eventually.

So too, much of our Perl programming is ephemeral. This aspect of Perl cuisine has been much maligned. You can call it quick-and-dirty if you like, but there are billions of dollars out there riding on the supposition that fast food is not necessarily dirty food.

We hope. Easy things should be easy, and hard things should be possible. For every fast-food recipe, there are countless slow-food recipes.

Perl Cookbook (eBook, PDF)

One of the advantages of living in California is that I have ready access to almost every national cuisine ever invented. It's said in Russia that there are more recipes for borscht than there are cooks, and I believe it. My mom's recipe doesn't even have any beets in it! But that's okay, and it's more than okay. Borscht is a cultural differentiator, and different cultures are interesting, and educational, and useful, and exciting.

So you won't always find Tom and Nat doing things in this book the way I would do them. Sometimes they don't even do things the same way as each other. That's okay - again, this is a strength, not a weakness. I have to confess that I learned quite a few things I didn't know before I read this book. What's more, I'm quite confident that I still don't know it all. And I hope I don't any time soon. I often talk about Perl culture as if it were a single, static entity, but there are in fact many healthy Perl subcultures, not to mention sub-subcultures and supercultures and circumcultures in every conceivable combination, all inheriting attributes and methods from each other.

It can get confusing. Hey, I'm confused most of the time. So the essence of a cookbook like this is not to cook for you it can't , or even to teach you how to cook though it helps , but rather to pass on various bits of culture that have been found useful, and perhaps to filter out other bits of "culture" that grew in the refrigerator when no one was looking. You in turn will pass on some of these ideas to other people, filtering them through your own experiences and tastes, your creativity and discipline.

You'll come up with your own recipes to pass to your children. Just don't be surprised when they in turn cook up some recipes of their own, and ask you what you think. Try not to make a face. I commend to you these recipes, over which I've made very few faces. Foreword Preface Next: Platform Notes Preface Contents: Our mathematicians mistrust your figures. Why should we entrust our money into your hands? What do you know that we do not?

Do you? He handed over the egg to the financial tycoons, who passed it amongst themselves trying to carry out the simple task.

At last they gave up. In exasperation they declared, "What you ask is impossible! No man can balance an egg on its point. Lightly but firmly, he pushed down on the egg with just enough force to crush in its bottom about half an inch.

When he took his hand away, the egg stood there on its own, somewhat messy, but definitely balanced. Before you know how, it seems an impossibility. Once the way is revealed, it's so simple that you wonder why you never thought of it that way before. Let me show you that easy way, so others may easily follow. Will you trust me?

Christopher Columbus. Many have since followed. Approaching a programming problem can be like balancing Columbus's egg. If no one shows you how, you may sit forever perplexed, watching the egg - and your program - fall over again and again, no closer to the Indies than when you began.

This is especially true in a language as idiomatic as Perl. This book had its genesis in two chapters of the first edition of Programming Perl. While revising the Camel, we realized that there was no way to do proper justice to those chapters without publishing the new edition on onionskin paper or in multiple volumes. The book you hold in your hands, published two years after the revised Camel, tries to do proper justice to those chapters. We trust it has been worth the wait. This book isn't meant to be a complete reference book for Perl, although we do describe some parts of Perl previously undocumented.

Having a copy of Programming Perl handy will allow you to look up the exact definition of an operator, keyword, or function. Alternatively, every Perl installation comes with over 1, pages of searchable, online reference materials. If those aren't where you can get at them, see your system administrator. Neither is this book meant to be a bare-bones introduction for programmers who've never seen Perl before.

That's what Learning Perl, a kinder and gentler introduction to Perl, is designed for. Instead, this is a book for learning more Perl. Neither a reference book nor a tutorial book, the Perl Cookbook serves as a companion book to both. It's for people who already know the basics but are wondering how to mix all those ingredients together into a complete program.

Spread across 20 chapters and more than focused topic areas affectionately called recipes, this book contains thousands of solutions to everyday challenges encountered by novice and journeyman alike.

We tried hard to make this book useful for both random and sequential access.

Each recipe is self-contained, but has a list of references at the end should you need further information on the topic. We've tried to put the simpler, more common recipes toward the front of each chapter and the simpler chapters toward the front of the book.

Perl novices should find that these recipes about Perl's basic data types and operators are just what they're looking for. We gradually work our way through topic areas and solutions more geared toward the journeyman Perl programmer. Every now and then we include material that should inspire even the master Perl programmer.

Each chapter begins with an overview of that chapter's topic.

This introduction is followed by the main body of each chapter, its recipes. These recipes range from short-but-sweet solutions to in-depth mini-tutorials. Where more than one technique is given, we often show costs and benefits of each approach.

As with a traditional cookbook, we expect you to access this book more or less at random. When you want to learn how to do something, you'll look up its recipe.

Even if the exact solutions presented don't fit your problem exactly, they'll give you ideas about possible approaches. Each chapter concludes with one or more complete programs. Although some recipes already include small programs, these longer applications highlight the chapter's principal focus and combine techniques from other chapters, just as any real-world program would. All are useful, and many are used on a daily basis.

Some even helped us put this book together. What's in This Book The first quarter of the book addresses Perl's basic data types, spread over five chapters. Chapter 1, Strings, covers matters like accessing substrings, expanding function calls in strings, and parsing comma-separated data. Chapter 2, Numbers, tackles oddities of floating point representation, placing commas in numbers, and pseudo-random numbers.

Chapter 3, Dates and Times, demonstrates conversions between numeric and string date formats and using timers.

Chapter 4, Arrays, covers everything relating to list and array manipulation, including finding unique elements in a list, efficiently sorting lists, and randomizing them.
