This book covers complex techniques for managing production-ready Perl programs and explains methods for manipulating data and objects that may have looked like magic before. It gives you necessary background for dealing with networks, databases, and GUIs, and includes a discussion of internals to help you program more efficiently and embed Perl within C or C within Perl. Major topics include practical use of packages and classes (object-oriented programming OOP); complex data structures; persistence (e.g.. using a database); networking; graphical interfaces, using the Tk tookit; interaction with C language functions; embedding and extending the Perl interpreter; selected internals; use of references, trapping errors through eval operator, non-blocking I/O, and using ties to trigger actions when data is accessed. You will emerge from thsi book a better hacker, and proud master of Perl
Perl Debugged provides the expertise and solutions developers require for coding better, faster, and more reliably in Perl. Focusing on debugging, the most vexing aspect of programming in Perl, this example-rich reference and how-to guide minimizes development, troubleshooting, and maintenance time resulting in the creation of elegant and error-free Perl code. Designed for the novice to intermediate software developer, Perl Debugged will save the programmer time and frustration in debugging Perl programs. Based on the authors' extensive experience with the language, this book guides developers through the entire programming process, tackling the benefits, plights, and pitfalls of Perl programming. Beginning with a guided tour of the Perl documentation, the book progresses to debugging, testing, and performance issues, and also devotes a chapter to CGI programming in Perl. Topics include: CGI programming; Perl "gotchas"; Perl Antibugging.
Working on the assumption that the reader has no formal training in programming, Perl Programming for Biologists demonstrates how Perl is used to solve biological problems. Each chapter opens with a set of learning objectives, provides numerous review questions and self-study exercises, and concludes with a bulleted summary of key points. The author incorporates numerous real-life examples throughout the text. Upon completing the book, readers are able to quickly perform such tasks as correcting recurring errors in spreadsheets, scanning a Fasta sequence for every occurrence of an EcoRI site, adapting other writers' scripts to one's own purposes, and most important, writing reusable and maintainable scripts that spare the rote repetition of code. Topics include: An Introduction to Perl; Variables and Data Types; Arrays and Hashes; Control Structures; Perl Subroutines; String Manipulation; Input and Output; Perl Modules and Packages; Bioperl.
Perl is one of the most important and powerful languages available today, and Professional Perl Programming offers an in-depth guide to exploiting some of its best features. With a densely packed tutorial straight from the experts, it is suitable for any experienced developer who wants to get more from this language. Topics include perl distributions, running perl on Unix, Windows, and other platforms, numbers and strings, perl operators, scalars, lists, arrays, hashes, complex data structures, typeglobs, expressions, statements and blocks, flow control and loops, subroutines, scope and visibility rules in Perl, Perl modules, autoloading modules, Perl file I/O, Terminal I/O, using the Perl debugger, object-oriented Perl, perl sockets and networking, and much more.
The computer program scripting language Perl is described here for those network administrators working with Windows. Rather than teaching how to run a Win32 network, this book teaches techniques for streamlining tasks. The text covers account maintenance, tools, crisis management, monitoring, reporting, logon scripts, processes, Win32 services, and ADSI and WMI. The book includes using Perl and COM to interact with Windows programs; writing autoloading Win32 services using Perl; managing drives, users, and group accounts, including backing up user databases and modifying user login profiles; securing system through effective permission management; scripts which enable you to locate data in the Registry, interact with ADSI and WMI, check for errors in event logs, managing running processes on local and remote machines, and manage user privileges. David Roth is the contributor of Win32:ODBC and varioius other popular Win32 Perl extensions.
