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.
Allison Randal is the assistant project manager of the Perl 6 core development team. She has been working closely with Damian Conway and Larry Wall on Perl 6 and has co written the "synopses" of Perl 6. She is dedicated to the success of the project and is one of the very first to learn about anything new that's proposed for Perl 6.
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.
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".
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.
