About the Books
Understanding Ruby Regexp
Example based guide to mastering Ruby regular expressions
Book details
Scripting and automation tasks often need to extract particular portions of text from input data or modify them from one format to another.
This book will help you learn Ruby Regular Expressions, a mini-programming language for all sorts of text processing needs.
The book heavily leans on examples to present features of regular expressions one by one. It is recommended that you manually type each example and experiment with them.
Exercises are included to test your understanding. Reference solutions are also provided.
Prerequisites
You should be familiar with programming basics. You should also have a working knowledge of Ruby syntax and features like string formats, string and Enumerable methods.
You are also expected to get comfortable with reading documentation, searching online, visiting external links provided for further reading, tinkering with illustrated examples, asking for help when you are stuck and so on. In other words, be proactive and curious instead of just consuming the content passively.

Feedback and Errata
I would highly appreciate it if you'd let me know how you felt about this ebook. It could be anything from a simple thank you, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors.

Ruby One-Liners Guide
Example based guide for text processing with Ruby from the command line.
About
When it comes to command line text processing, there are several well known tools like grep for filtering, sed for substitution and awk for field processing. Compared to such tools, Ruby has a feature rich regular expression engine, plenty of builtin modules and a thriving ecosystem. Another advantage is that Ruby is more portable.
Ruby One-Liners Guide will show examples for filtering and substitution features, field processing, using standard and third-party modules, multiple file processing, how to construct solutions that depend on multiple records, how to compare records and fields between two or more files, how to identify duplicates while maintaining input order and so on.
This book heavily leans on examples to present features one by one. Exercises are also included to test your understanding.
Prerequisites
You should be comfortable with programming basics and have prior experience working with Ruby. You should know concepts like blocks, be familiar with string/array/hash/enumerable methods, regular expressions etc.
You should be familiar with command line usage in a Unix-like environment. You should also be comfortable with concepts like file redirection and command pipelines. Knowing the basics of the grep, sed and awk commands will come in handy as well.
You are also expected to get comfortable with reading manuals, searching online, visiting external links provided for further reading, tinkering with illustrated examples, asking for help when you are stuck and so on. In other words, be proactive and curious instead of just consuming the content passively.
