I liked the slowness of it but I think there should have been more exercises. It also leans heavy on Perl, which I found good, though unexpected.

This is not the first time I've tried to learn Regular Expressions. But other than some basic syntax, it never clicked. But I think this book provided the kind of introduction I needed to get me to not just know the syntax, but to get an understanding of how regular expressions work and how to learn its power. In short, it is not a reference, but a book that teaches me how to learn. And that is what I had not had before.

I've come across regular expressions on numerous occasions in the course of

Very slim introduction to regular expressions. I noticed a couple of errors that I'll report to O'Reilly. But if you want a quick read to get you up to speed with regular expressions then this will probably do the trick.

Good introduction I think. It's good that it provides a few texts to play with and doing the exercises while reading along makes learning much easier. Some of the tools are a bit dated but you can just google equivalent ones. Also, it focuses a lot on Perl so I skipped some parts. Pretty sure I won't remember all the special characters and I will continue to google them most of the time but it's useful to know the main ones and to know what tools are out there and what they're called (positive/n ...more

Great intro

For such a short book, this goes into too much detail on on line regex simulators and on different implementations of regex, rather than just sticking to the basics.

1. połowa podręcznika to rozdziały, dużo obrazków, więc czyta się ją bardzo szybko. Zaletą tej książki jest, że wyrażenia regularne są opisane w najróżniejszych programach, i to bardzo przystępnie. Jest ona raczej dla początkujących, ale mających jako takie doświadczenie z komputerem. Druga połowa to oznaczenia, opisy innych książek, kody znaków (dobrze, że nie chińskich, bo wtedy tom byłby gruuuby), inne kody, słowniczek, zapchane czym się da. Niestety tylko 3 gwiazdki, za małą ilość treści, je ...more

I've updated my review from 4 to 5 stars as the practical application for what it taught me have started to show. I've saved quite a bit of time already due to what I've learned from this book.

I now have three things I will quote at people:
"The most elemental problem people have with technology is literacy"
"Excel is evil and lies!"
"If you work with a lot of text you owe it to yourself to learn RegEx"
