Summary: Great subject - poorly written book
Review: Not just what the book tries to say, it is how it says. In this regard, this book falls short of its promiss.I hope the author will re-write/organize the book to make it fun to read and provide many little examples (eg. like Programming Perl, Perl Cookbook,etc..) to make it fun to read.

Summary: Wordily book
Review: The author talks so much of unrelated stuff outside regular expresions. However he gives good examples and cases for the use of regex.

Summary: Extraordinary
Review: This book opened up a whole new world of computing for me. Regular expressions will save you unbelievable amounts of time. The author's explanations are wonderful. No stone is left unturned. You will never think about text the same way again.

Summary: Excellent Apporach to Writing Regex!
Review: This book is quite possibly the most important book I have read about the philosophical approach to programming regex. Not just for those wanting to program Perl.

Summary: Finally an instructional book that actually teaches!
Review: Jeffrey Friedl is one of those rare authors who actually knows how to teach instead of simply trying to impress people with his knowledge, as so many authors try to do. From cover to cover, he takes a thorough, methodical approach to regular expressions and doesn't leave ANY stone unturned, makes NO ASSUMPTIONS about his readers' knowledge, and leaves NOTHING to chance. He is completely knowledgeable about regular expressions and genuine in his desire to pass this knowledge to his readers. Anyone new to regular expressions will have gotten their money's worth by the time they finish the second chapter. Now I just wish someone would pay Jeffrey Friedl to re-write half the computer books on my reference shelf! Authors take note! We don't care how smart you are - we measure you by your ability (and sincere desire) to pass this knowledge on to us! Jeffrey Friedl sets the standard with Mastering Regular Expressions.

Summary: Real disappointment on "Perl Regular Expressions"!
Review: The author should NEVER adovacate programming with readability(abstraction) and efficiency at the same time. Taking advantage of the perl internals(implementations) for the purpose of optimization in regular expression matching is the worst programming practice since dos era!
Rating:
Summary: Reading time repaid a thousandfold
Review: For everyone programming in a UNIX environment or with tools coming from it (e.g., grep & friends). Good read. Easily understood. Applying regular expressions saves you unbelievable amounts of time. This book has probably the best immediate earnings/cost ratio of all books I ever bought. Buy it. The sooner the better.
Rating:
Summary: Unclear and a general disappointment
Review: I found this book to be poorly written and a general disappointment. The entire book could have (and should have) been condensed to about 20 pages. I have yet to find it helpful vs. the reg. expression cheat sheet that comes with any Perl book.

Summary: The source for regular expression info
Review: Once again, it is an O' Reilly book that stands out above the rest. This book does a great job explaining and comparing Perl, sed, awk, grep, egrep, etc. syntax for regular expressions. It is lacking on regex and regexp libraries, but in depth enough to get the idea.
