Ruby Regexp

a magical tool for text processing

About the Book

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.

You should have prior experience working with Ruby, should know concepts like blocks, string formats, string methods, Enumerable, etc.

Exercises are also included to test your understanding.

About the Author

Sundeep Agarwal
Sundeep Agarwal

Sundeep Agarwal is a lazy being who prefers to work just enough to support his modest lifestyle. He accumulated vast wealth working as a Design Engineer at Analog Devices and retired from the corporate world at the ripe age of twenty-eight. Unfortunately, he squandered his savings within a few years and had to scramble trying to earn a living. Against all odds, selling programming ebooks saved his lazy self from having to look for a job again. He can now afford all the fantasy ebooks he wants to read and spends unhealthy amount of time browsing the internet.

When the creative muse strikes, he can be found working on yet another programming ebook (which invariably ends up having at least one example with regular expressions). Researching materials for his ebooks and everyday social media usage drowned his bookmarks, so he maintains curated resource lists for sanity sake. He is thankful for free learning resources and open source tools. His own contributions can be found at https://github.com/learnbyexample.
