Get started with Perl 5 and learn the important core concepts of Perl programming, such as variables, flow control, expressions, and I/O. Additionally, this book covers pattern matching and shows that Perl is extremely flexible and powerful, and that it isn’t afraid of the cloud. After reading and using this book, you'll be able to start writing your own powerful scripts to solve many web and programming problems. This is a book for those of us who believed that we didn’t need to learn Perl, and now we know it is more ubiquitous than ever. You’ll see that Perl has evolved into a multipurpose, multiplatform language present absolutely everywhere: heavy-duty web applications, the cloud, systems administration, natural language processing, and financial engineering. This book provides valuable insight into Perl’s role regarding all of these tasks and more giving you a great start in your Perl programming adventure. You will: Perform operations on scalar values Use scalar, array, and associative array variables Work with flow control statements such as if, unless, while, until, for, and foreach Read and write directly to files with file handles Use conditional expressions such as numeric and string comparison, regular expressions, file testing, and Perl statements Format output with format statements Search for and replace sub-strings within a string using regular expressions Master Perl utilities such as split, join, index and more Control the file system and processes from within a Perl script Build functions for tasks including handling the scope of variables Import existing modules into your Perl script.

William Rothwell's Advanced Perl Programming continues where his previous book left off, more or less, as it guides you through advanced techniques of the Perl programming language starting with command-line options, references, and arrays and hashes from advanced data types. Next, you'll learn about typeglobs for symbolic entries. Additionally, you'll see advanced subroutine handling, then packages and namespaces. Furthermore, you'll build advanced modules and install CPAN modules. Unlike Java and C++, modules have been around in Perl for a long time now. Along the way, you'll learn and use POD mark up language for Perl documentation. Moreover, you'll get a survey of the many advanced features and data structures of the current Perl programming language. You'll also get a survey of the new features of the latest Perl 5.x release. After reading and using this book, you'll have the tools, techniques, and source code to be an expert Perl programmer. You will: Carry out command-line parsing and extract scripts Create references; return values from a reference; work with the ref Function and strict refs Work with advanced Perl data types using arrays, hashes, and hash of hashes Use Typeglobs for symbol table entries Build modules and install CPAN modules Write documentation for Perl using POD Work with the newest features in Perl, including the smartmatch operator, yada yada, automated regex modifiers, the CORE namespace and more.

Master intermediate to advanced techniques of the Perl programming language starting with a focus on regular expressions and some of their advanced features. This book then covers other pro-level features, including formatted output, file handling, and more. Additionally, you'll learn and explore the most useful built-in variables, pragmas, and modules available in the Perl language. Furthermore, you'll work with geometry managers and get a thorough treatment of graphical user interface development using Perl/TK and widgets. Lastly, you’ll cover debugging techniques. Pro Perl Programming is a professional-level reference guide on Perl and includes important aspects of it that you need as a professional programmer. You will: Program regular expressions including atoms, smartmatch operators, and more Use advanced features such as HiRes Time, slurp() functions, Critic, Tidy and many more functions Handle advanced formatted output such as printf and sprintf Explore useful built-in variables, including status variables, separator variables, and the signal handle variable Explore and use Perl's built-in modules, including the Pragma modules Work with Perl/TK and its widgets-like geometry managers, frames, labels, buttons, check buttons, radio buttons, scrollbars, scales, entries, and menus.
