Intermediate Perl
Perl is a versatile, powerful programming language used in a
variety of disciplines, ranging from system administration
to web programming to database manipulation. One slogan of
Perl is that it makes easy things easy and hard things
possible. Intermediate Perl is about making the leap from
the easy things to the hard ones.
Originally
released in 2003 as Learning Perl Objects,
References, and Modules and revised and updated for Perl
5.8, this book offers a gentle but thorough introduction to
intermediate programming in Perl. Written by the authors of
the best-selling Learning Perl, it picks up where that book
left off. Topics include:
Packages and namespaces
References and scoping
Manipulating complex data structures
Object-oriented programming
Writing and using modules
Testing Perl code

Following the successful format of Learning Perl, we
designed each chapter in the book to be small enough to be
read in just an hour or two, ending with a series of
exercises to help you practice what you've learned. To use
the book, you just need to be familiar with the material in
Learning Perl and have ambition to go further.
Perl is a different language to different people. It is a
quick scripting tool for some, and a fully-featured
object-oriented language for others. It is used for
everything from performing quick global replacements on text
files, to crunching huge, complex sets of scientific data
that take weeks to process. Perl is what you make of it. But
regardless of what you use Perl for, this book helps you do
it more effectively, efficiently, and elegantly.
Intermediate Perl is about learning to use Perl as a
programming language, and not just a scripting language.
This is the book that turns the Perl dabbler into the Perl
programmer.
