Perl 6 and Parrot Essentials
Distilling many years of Perl experience--including an insiders look at Perl development (the authors are members of the Perl 6 core development team)--Perl 6 and Parrot Essentials, 2nd Edition is an unparalleled preview of major changes in the widely-anticipated Perl 6. This sneak peek of what's coming in Perl includes succinct but thorough coverage of groundbreaking new developments in Parrot--the language-independent interpreter engine that will execute code written in the new Perl 6 language. Designed to be language independent, Parrot can be used to interpret other dynamic languages such as Python, Tcl, Ruby, and even Java. Perl 6 and Parrot Essentials also uncovers the most revolutionary change in the language itself--Apocalypse 12 on objects. The Apocalypse design documents (in the sense of "revealing", not "end-of-the-world") explain significant changes in new Perl 6 features, numbered according to the chapters in O'Reilly's landmark Camel book, Programming Perl. Apocalypse 12 is the result of cutting-edge research in object-oriented languages and is guaranteed to grab the attention of any serious Perl programmer. Perl 6 and Parrot Essentials also includes expanded coverage of Apocalypse 5 (regular expressions) and Apocalypse 6 (subroutines). Perl 6 and Parrot Essentials is the only book available to chart the course of the long but fruitful voyage of Perl 6. It reveals all the ingenious developments that will make Perl 6 more powerful and easier to use. Perl gurus and programmers alike will rely on this slim but essential book for both a clear view of the Perl horizon and to ensure they hit the ground running once this important new version of Perl is released.

An excellent source of information on a moving target
Published by Thriftbooks.com User , 15 years ago
If you are just curious about Perl 6 and Parrot, this is a good book. If you are planning on diving into the language and want to know some complex internals, this is a good book. In fact, either way you slice it, it is pretty darn good. The only caveat is that this is not a tutorial style book and probably does not completely cover the Perl 6 language. This of course is clearly stated in the book itself since this book was published before the release date of a perl implementation of Perl 6 was even decided upon. But now that date looks like it is over the horizon. There is chatter on the wires that 'Rakudo Star' will be released in April-ish 2010. This most likely will be the first release of perl 6. The question then is; is this book relevant? And the answer is unequivocally yes. It gives you a lot of information on Perl 6 syntax and features and provides a pretty through overview of Parrot. It is a densely packed book, a lot like K & R's book on C. But it is readable and usable even as reference. Well worth buying.
Good reading in many ways for many users
Published by Thriftbooks.com User , 20 years ago
I found this book well written and enjoyable. As someone interested in how a team goes about developing a new language, parts of it read like a good NY Times feature. For anyone writing Perl professionally, this is a good heads-up on where their language is going. For introductory Perl users, esp those coming from another language, the Design Philosophy and quick language review sections are very useful for 'grokking' Perl at a high level and then seeing how the pieces fall into place.
Serious Perl programmers only
Published by Thriftbooks.com User , 20 years ago
As you can imagine, this short book is only for the serious Perl guru. The first half of the book is on the Perl 6 language and is so terse that it's only readable by experienced Perl programmers. The second half of the book covers Parrot, the new Perl Virtual Machine. This is seriously hard core material, which is useful if you plan to write your own compiler to fit on top of the machine. Doubtless this is some cutting edge and impressive material, but the book has no ramp for beginners. If your job depends on high-end Perl, you will want to read this book. If you are an average Perl user you can probably wait for the next version of Programming Perl.
Parrot ~ .NET ?!
Published by Thriftbooks.com User , 20 years ago
Perl 5 is the current version of Perl out there in active use. But a cadre of key developers has been steadily tooling up a major upgrade, Perl 6. This book gives you a detailed preview that claims to be an accurate description of what it will be, when it is officially released. In part, of course, so that existing Perl users can plan for the future. But the book is also a call to arms. If you are enticed and intrigued by Perl 6, and would like to contribute to its development, then please do so! The authors show how to join the development team. An all-volunteer effort, mind you. They can't pay you anything.Speaking of which, that brings up the second part of the book. As part of the Perl 6 effort, there is a related project, Parrot. It will be a language independent virtual machine that can convert Perl 6 source to a byte code binary. And also do likewise for Tcl, Python, Java and other languages.Does this ring any bells? Sounds in the spirit of Microsoft's .NET. That was and is a massive task in design and implementation. No one outside Microsoft, and precious few inside, knows how much it is costing. What is impressive is that here in Parrot, we have a bunch of volunteers trying a similar effort, with no $budget to speak of. Can they do it? The authors strongly argue, "yes".
