How is your knowledge of regular expressions?
Spending a few days to learn them well² is really worth it.
--
² it's also worthwhile to know how they are working under the hood if you want to write high-performance regular expressions
- geocrasher 6y ago^^^^ I'm not a dev, but regex is so much better when you understand what it's doing (I'm not claiming that knowledge in full!) The Book: http://regex.info/book.html http://regex.info/book.html I bought an older edition for a lower price, got through 7 or 8 chapters, and never touched it again- and I STILL gained huge amounts of knowledge and am much better at regex than I ever thought I'd be. Highly recommended!
- XCSme 6y agoHonest question, why would you read a book about Regex? I personally find it a lot easier to learn how it works just by going to sites like https://regex101.com/ https://regex101.com/ and trying things out while reading their docs.
- geocrasher 6y agoBecause it was highly recommended to me by a sysadmin I respected who was extremely proficient with regex. Sure, there are sites too, but after reading the book, the sites weren't really needed. I personally got more value from the book. It's subjective, of course.
- thatcodingdude 6y agoI love them and went through https://regexcrossword.com/ https://regexcrossword.com/ for fun, they're great tools. I have no idea how they work under the hood though !
- geocrasher 6y agoKnowing how they work under the hood will help you to write better expressions that perform well and don't waste performance.
