Learning Regular Expressions

This book makes the subject approachable for a wider audience. I was able to start reading and modifying regex after a couple weeks with it.

I use regular expression searches and replaces periodically in my work and keep this book and another for reference. It seems to have most of what I need.

For several years, I have recommended Sams Teach Yourself Regular Expressions in 10 Minutes to students needing a concise and clear, tutorial introduction. This is a reprint of that title, with just a little updating of the appendix on implementations. I have looked at more recent books on regular expressions, but I think Forta is still the best introduction.

An easy read that provides enough detail to get you going. You can easily get through the entire book in a day and actually feel like you've learned something really useful.

Llego rapido pero con la contracubierta sucia, el interior esta bien 👍

well organized, good examples, straightforward

While you can learn a lot on the web, this book gives you a very clear understanding of RegEX. I likes the way the writer explained things. Good baseline for a start. If you already know the basics then this would not be for you.

Defective from factory. The pages have bumps. I don't know a better way to explain it.

That great value of this book is to explain in clear terms what are the regular expressions in most implementations. There are good examples and good explanations. It may be worth the price, but remember it's a very small book.I read it on the Windows Kindle and the Kindle Web Reader. In the Web Reader, the code cannot be copied to be tested. In the Windows Kindle, we can copy the code but a copyright notice is always added.I should mention two problems:1. The code and the result are not always correct. More often, the explanations are more precise than the code or the result. You have to check constantly.2. The author decides that a feature is not implemented enough to be explained. In my case, all the languages, the tools and text editors I use were supporting those features. And, most programmers will download a library in order to complete its own tools. Many are complex and would profit from a good pedagogue like this author, albeit a little lazy.It's a good book for someone who want to have a better understanding of more advanced features. But if you want to know the limits of the regular expressions, you will be left in the dark because too many features are not explained:- accented characters and national character sets- union and intersection in character classes- \A and \G boundary matchers- Greedy and lazy quantifiers are not defined in the same manner as in Java- Reluctant and possessive quantifiers- Quotation- Named capturing groups- Flags (minimally covered), and flagged groups- Independent non-capturing groups- Comments- Replace (very minimally covered)- Zero-length match- RecursionFor example, I still don't know what I cannot do with regular expressions. I didn't solve my problem which seems to require a variable length negative lookbehind condition. It is mentioned that for lookbehind condition, only fixed length are supported. But what can we do when you have a variable length condition? I still have to search by myself.

This is the best intro to this subject. It gently goes thru examples at a pace you can easily follow. Recommended for those that need to build their confidence with regular expressions.

I am an experienced excel vba developer but I discovered Regular Expressions only recently while trying to figure out a solution for a programming problem. I was fascinated by the topic and wanted to become proficient at this. I was disappointed at first when I realised that the book is really short but after reading the first chapter I felt it was exactly what I needed: a straight to the point, user friendly guide to get me started rather than a huge reference book.The writing style is clear and the content is well structured with plenty of examples for each topic.I am happy with my purchase.

It is a very good introduction to Regular Expressions. They are introduced step by step with many examples. It starts quite "low level", so I was worried at the beginning whether the book would be worthwhile for me, because I already knew the basics of regular expressions.But after a few chapters I learned a lot.I particularly like the prose style of writing and the structure of the individual lessons.I have to reduce one point, because there are mistakes in some of the examples. But more often, the analysis that follows an example contains the correct expressions, but not always.I read it as an e-book, the format is very suitable for this.

Read it in a weekend and was fully prepped for Grok patterns in Elastic Logstash. Well explained examples
