Raku Fundamentals : A Primer with Examples

Gain the skills to begin developing Raku applications from the ground up in this hands-on compact book, which includes a foreword from Larry Wall, creator of Perl. Youll learn enough to get started building with Raku, using Rakus gradual typing, handy object orientated features, powerful parsing capabilities, and human-usable concurrency. This book has been updated to include the latest version of Raku based upon the Perl 6.d major version which includes over 3,400 new commits in its specification.

After a short introduction, each chapter develops a small example project, explaining the Raku features used. When the example is done, youll explore another aspect, such as optimizing further for readability or testing the code. Along the way youll see Raku basics, such as variables and scoping; subroutines; classes and objects; regexes; and code testing.

When youve mastered the basics, Raku Fundamentals moves onto more advanced topics to give you a deeper understanding of the language. Youll learn, amongst other things, how to work with persistent storage, how to generate good error messages, and how to write tricky applications such as a file and directory usage graph and a Unicode search tool.
