This one day tutorial will introduce beginner and intermediate Perl programmers to the full functionality of Perl’s regular expressions.
The day focuses on the pattern-matching features in Perl 5.6 and 5.8. The morning session explores the principles and mechanisms underlying all Perl regular expressions. You will see how the highly compact syntax of Perl patterns controls a built-in pattern-matching “engine” and learn how to design and construct Perl regexes to drive that engine efficiently. We will also look at the four principal uses of regexes in Perl, discussing a number of uniquely Perlish regex idioms. By lunch time, Perl’s regexes will no longer seem like a mystery wrapped in an enigma wrapped in line-noise.
