Learning Perl Objects, References amp;amp; Modules [Electronic resources] نسخه متنی

Preface

Ten years ago, I wrote the first edition of Learning
Perl. In the intervening years, Perl itself has grown
substantially from a "cool"
scripting language used primarily by Unix system administrators to a
robust object-oriented programming language that runs on practically
every computing platform known to mankind.

Throughout its three editions, Learning Perl
remained the same size (about 300 pages) and continued to cover much
of the same material to remain compact and accessible to the
beginning programmer. But there is much more to learn about Perl than
there was ten years ago.

This book may be entitled Learning Perl Objects,
References, and Modules, but I like to think of it as just
Learning More Perl.[1]
This is the book that picks up where Learning
Perl leaves off. It shows how to use Perl to write larger
programs.

[1] Don''t ask why it isn''t called
that. We must have had 30 emails on the subject.

As in Learning Perl, each chapter in this book
is designed to be small enough to read in just an hour or two. Each
chapter ends with a series of exercises to help you practice what
you''ve just learned, with the answers in the
Appendix for your reference. And like Learning
Perl, the material in this book was developed for a
teaching environment and used in that setting, including for our own
use at Stonehenge Consulting Services as we present onsite and
open-enrollment trainings.

You don''t have to be a Unix guru, or even a Unix
user, to benefit from this book. Unless otherwise noted, everything
in this book applies equally well to Windows ActivePerl from
ActiveState, and all other modern implementations of Perl. To use
this book, you just need to be familiar with the material in
Learning Perl and have the ambition to go
further.
