'This book lives up to everything I have come to expect of the O'Reilly Nutshell series, being both technically accurate and highly readable. I would recommend it to anyone needing to extend or embed perl as well as to those wishing to move to more complex perl programming than they might be doing at the moment.' - Tom Hughes, Cvue, January 2000
So you've learned Perl, but you're getting frustrated. Perhaps you've taken on a larger project than the ones you're used to. Or you want to add a user interface or a networking component. Or you need to do more complicated error trapping. Whether your knowledge of Perl is casual or deep, this book will make you a more accomplished programmer. Here you can learn the complex techniques for production-ready Perl programs. This book explains methods for manipulating data and objects that may have looked like magic before. Furthermore, it sets Perl in the context of a larger environment, giving you the background you need for dealing with networks, databases, and GUIs. The discussion of internals helps you program more efficiently and embed Perl within C or C within Perl. Major topics covered include: Practical use of packages and classes (object-oriented programming); Complex data structures; Persistence (e.g., using a database); Networking; Graphical interfaces, using the Tk toolkit; Interaction with C language functions; Embedding and extending the Perl interpreter In addition, the book patiently explains all sorts of language details you've always wanted to know more about, such as the use of references, trapping errors through the eval operator, non-blocking I/O, when closures are helpful, and using ties to trigger actions when data is accessed.You will emerge from this book a better hacker, and a proud master of Perl.

provided for those not familiar with the underlying issues).
At the script level there are discussions of refs/globs and GC, symbol tables, OO, eval and tie. At the C level, extending, embedding and operation of the perl interpreter is discussed at length for up-to-date versions of perl5. These concepts are reinforced through examples built
around databases, GUIs, networking and dynamic code generation.
The writing style is clear and concise and clears up many common misconceptions people have about Perl.
One highly useful feature is a summary comparison with other languages and the end of each chapter, contrasting the Perl functionality
against Tcl, C/C++, Python and Java.
This text is an excellent companion to the Blue Camel providing a broader view of advanced language features. An essential companion for serious perl developers.
I felt at times the "perl" actually got lost in the examples, as they tended to focus on the abstract problem more than the perl code being written to solve it, but this is a minor issue.
There is a lot of content covered and the author does a reasonable job of explaning the topics in an efficient manner. Warning to the reader looking for advanced perl/Tk -- there isn't any in this book. The perl/Tk part was the reason I bought this, but was a bit disappointing.
Compared to the swarm of perl books on the market, this is one of the top titles. Worth its price many times over.
I've read through 3 quarters of the book but the only thing that I couldn't stand was the author's usage of the English language. He seems to have concentrated on the English part of the book as much as the perl part of it. :( Usage of words/phrases like "kosher", "syntactic sugar" are irritating and convey the impression that the author wants to show off his command of English.
Nevertheless, this is, as far as I can think, one of the most essential perl reference books for the serious programmer. Ignore the English and concentrate on perl and you'll have a better journey!
1. Programming Perl by Wall, Christiansen & Schwartz.
2. Mastering Regular Expressions, by Friedl.
3. Advanced Perl Programming, by Srinivasan.
Taken together, these three books are *THE* way to learn as much Perl as you want, or as little as you need. Just the right level of detail. There's some unavoidable duplication, but not enough to be bothersome.
If you just want to reformat your C to look like perl, go ahead and get one of the many wordy but insubstantial "learn in n days" books. But if you want to master the truly remarkable "Swiss-Army Chainsaw" of programming languages, these are the books for you.
The best part of this book is great and profound. One good example is: Men were sent to the moon while FORTRAN and COBOL ruled the roost, which proves that you can get a whole lot done if you don't indulge in language wars.
The book covers too many topics to repeat here. If you finished the Camel book and still need more information about Perl, then this is the book to get.
(To be fair, chapter 20 of /Advanced Perl Programming/ is a very good discussion of the internals of the Perl interpreter-compiler. However, that's of real interest to very very few people.)
Instead of spending their time and money on this book, learners are better off reading the other, more recent good books on Perl, flipping thru modules in CPAN, and subscribing to The Perl Journal.
