Perl 6 Now: The Core Ideas Illustrated with Perl 5 Cover

 

Synopses & Reviews

Publisher Comments:

The book really shines in its code examples: short, clear and to the point; the author repeatedly shows how something can be done in Perl 5 code and how it's expected to work in Perl 6. — Joseph Brenner, Slashdot Contributor

The author guides you through creating variables and accessing the data in them. You will find out how to save memory by only using the OO variable types when you need them. — Mr. Muskrat, Perl Monks

..after reading Scott Walter's gentle overview, I am actually looking forward to Perl 6 - eagerly anticipating rather than dreading its arrival. — Anthony Lawrence, http: //aplawrence.com

Perl 6 Now: The Core Ideas Illustrated with Perl 5 is perfect for those eager to see where Perl is headed, Perl 5 programmers who want to know that their favorite tricks will still work in some form, and programmers wishing to open their minds to advanced programming topics.

Perl 6 generalizes the language, making it more extensible, eliminating longstanding pitfalls, and adding new concepts. Thanks to some clever people and impressive efforts, many of these new features work in Perl 5, so you can start using them now in production-level code.

The book teaches the basics from a Perl 6 perspective, touching on variable interpolation, datastructure use, object construction, threads, closures, symbol tables, and other core features. It then introduces continuations, coroutines, binding (or aliases), hyper operators that work on lists of data at once, set operators that work on complex datatypes, lightweight multidimensional arrays, strong type checking, autoboxing, precompilation, automatic module dependency installation, and more.

Though Perl 6changes the fundamental syntax in some areas, Perl 5 code isn't left in the lurch. Thanks to PONIE, code from both versions may coexist in a single program. You'll need to adjust only a few habits and learn a few new things, and this early adopter's guide will help you do these things.

Book News Annotation:

To help programmers keep pace with Perl upgrades, Walters (involved with the Phoenix Perl Mongers and other Perl projects) introduces the new and improved features of Perl 6 by building on Perl 5 Open Source design themes. E.g., a table compares Perl 5 and 6 operators. While he covers some topics for novices and programmers in other languages, the intended audience is Perl programmers curious/anxious about this "perlier Perl". Source code for the book is downloadable from an auxiliary Web site.

Synopsis:

This pragmatic book is a guide to Perl 6 language features, as well as an advanced teaching guide for Perl 5 programmers. It's the most up-to-date Perl book available. Examples are provided for both Perl 5 when using modules to back port Perl 6 features, and Perl 6 native examples.

Examples are provided for both Perl 5 when using modules to back port Perl 6 features, and Perl 6 native examples. This book's pragmatic approach shows you how to bootstrap new features onto the code you write day-to-day.
Perl 5 has long been missing important features but no agreement could be reached on the form they should take in the language, or even if they should be included. The announcement of the Perl 6 project has spurred development of Perl 5. As features are accepted into the Perl 6 design and Larry Wall finalizes the form it will take, many features are being added back into Perl 5. Perl 5.9, with opinional extensions from CPAN, hardly resembles the original Perl 5 language that first came out 9 years ago. Modern Perl is cleaner, more helpful, less error prone, more expressive, more scalable, and better suited to what people want to do in this day and age.
