Book Description – Mastering Regular Expressions: Powerful Techniques for Perl and Other Tools (Nutshell Handbooks)
Download Mastering Regular Expressions: Powerful Techniques for Perl and Other Tools (Nutshell Handbooks) pdf– Regular expressions are a useful tool for manipulating text and data. If you’ve never used them before, this book will introduce you to a whole new world of data mastery. If you already use them, you’ll appreciate the depth of knowledge and coverage provided in this book. This book will blow your head if you think you know everything there is to know about regular expressions. Regular expressions may save you time and frustration while working with documents, mail messages, log files, or any other type of text or data. Regular expressions, for example, might be quite valuable when writing a CGI script for the World Wide Web that contains a wide range of text and data. Regular expressions aren’t a stand-alone tool; they’re used in conjunction with other tools. Rather, they are a component of a larger service. Grep is a good illustration of this. Regular expressions are currently used in a number of situations, including:
- Languages for writing scripts (including Perl, Tcl, awk, and Python)
- Proofreaders and editors (including Emacs, vi, and Nisus Writer)
- Programming environments (including Delphi and Visual C++)
Many of these programs were originally developed for UNIX, but they are now available for a number of platforms, including DOS/Windows and macOS, allowing you to use them at home. Regular-expression libraries are also available in a number of popular programming languages, allowing you to include regular-expression support in your own programs, such as applets. There are certain subtle but useful ways of thinking that may be taught while using regular expressions. Jeffrey Friedl has spent years helping others understand and use regular expressions on the Internet. In this book, he leads you through the steps of developing a regular expression that gets the job done. Regular expressions aren’t used in isolation. This book looks at and utilizes a variety of tools in a variety of applications, with a concentration on Perl. Regular expressions in Perl are plentiful and expressive. In the hands of an expert, however, what is power may be hazardous to the unsuspecting. This book will help you navigate the minefield that is the route to expert status.
About the Author
Jeffrey Friedl grew up in the countryside of Rootstown, Ohio, and dreamed of becoming an astronomer until he came across an unused TRS-80 Model I in the chemistry lab one day (bristling with a full 16K of RAM, no less). In 1980, he started using Unix (and regular expressions), and he went on to get degrees in Computer Science from Kent (BS) and the University of New Hampshire (MS) (MS). He spent eight years developing kernels for Omron Corporation in Kyoto, Japan, before relocating to Silicon Valley in 1997 to apply his regular-expression expertise to financial news and data for a startup called “Yahoo!”
When he has spare time, Jeffrey likes playing Ultimate Frisbee and basketball with his Yahoo! colleagues, programming his home, and feeding the squirrels and jays in his backyard. He also likes spending time with his wife Fumie and working on their first “software project” together, which will be released in the Fall of 2002.
