Mastering Perl-brian d foy

Chapter 1, Introduction: Becoming a Master An introduction to the scope and intent of this book.
Chapter 2, Advanced Regular Expressions More regular expression features, including global matches, lookarounds, readable regexes, and regex debugging.
Chapter 3, Secure Programming Techniques Avoid some common programing problems with the techniques in this chapter, which covers taint checking and gotchas.
Chapter 4, Debugging Perl. A little bit about the Perl debugger,

writing your own debugger, and using the debuggers others wrote.
Chapter 5, Profiling Perl. Before you set out to improve your Perl program, find out where you should concentrate your efforts.
Chapter 6, Benchmarking Perl. Figure out which implementations do better on time, memory, and other metrics, along with cautions about what your numbers actually mean.
Chapter 7, Cleaning Up Perl. Wrangle Perl code you didn’t write (or even code you did write) to make it more presentable and readable by using Perl::Tidy or Perl::Critic.
Chapter 8, Symbol Tables and Typeglobs. Learn how Perl keeps track of package variables and how you can use that mechanism for some powerful Perl tricks.
Chapter 9, Dynamic Subroutines. Define subroutines on the fly and turn the tables on normal procedural programming. Iterate through subroutine lists rather than data to make your code more effective and easy to maintain.
Chapter 10, Modifying and Jury-Rigging Modules. Fix code without editing the original source so you can always get back to where you started.
Chapter 11, Configuring Perl Programs. Let your users configure your programs without touching the code.
Chapter 12, Detecting and Reporting Errors. Learn how Perl reports errors, how you can detect errors Perl doesn’t report, and how to tell your users about them.
Chapter 13, Logging. Let your Perl program talk back to you by using Log4perl, an extremely flexible and powerful logging package.
Chapter 14, Data Persistence. Store data for later use in other programs, a later run of the same program, or to send as text over a network.
Chapter 15, Working with Pod. Translate plain ol’ documentation into any format that you like, and test it, too.
Chapter 16, Working with Bits. Use bit operations and bit vectors to efficiently store large data.
Chapter 17, The Magic of Tied Variables. Implement your own versions of Perl’s basic data types to perform fancy operations without getting in the user’s way.
Chapter 18, Modules As Programs. Write programs as modules to get all of the benefits of Perl’s module distribution, installation, and testing tools.
