Write good regexes and parsers with the Perl 6 programming language. You'll see how regexes are
used for searching parsing and validation: in particular the grammar extension makes them
uniquely suitable for parsing the main focus of this book. Written by Perl 6 expert Moritz
Lenz a core contributor of Rakudo Parsing with Perl 6 Regexes and Grammars starts from the
very basics of regular expressions and then explores how they integrate with regular Perl 6
code. Then follows a deeper exploration of how regexes work under the hood and a discussion of
common techniques for constructing regexes and exploring the data under scrutiny. Later
material goes beyond relatively simple formats to reusable named regexes and grammars which
permit code reuse in grammars and shows how to write parsers for more involved data formats.
Error reporting and case studies wrap up the topic. While regexes allow you to search for
patterns in text and validate input Perl 6 regexes advance that concept: you'll see how they
are easier to read yet much more powerful than the traditional Perl-compatible regular
expression. With improved reusability and backtracking control you will be able to write
complete parsers with the help of this book. What You'll Learn Discover the building blocks of
Perl 6 regexes Handle regex mechanics and master useful regex techniques Extract data and work
with patterns among these use cases Reuse named regexes and other grammars as components or
templates Write full parsers including advanced error reporting and data extraction Learn how
to parse nested scopes and indention-based formats Who This Book Is For Those with at least
some prior experience with Perl programming but who may be new to Perl 6 aswell as searching
and parsing.
