Code snippets, example files and sample chapters are available on GitHub [3]

The book uses plenty of examples and regular expressions are also covered from scratch. The book is suitable for beginners as well as serves as a reference. Hope you find it useful, I would be grateful for your feedback and suggestions.

I used pandoc+xelatex [4] to generate the pdf.
