Use Online Tools: There are many online regex testers and visualizers that can help you see how your patterns match against sample text. These tools often provide explanations for each part of the regex. I personally use https://regexr.com/. - Source: dev.to / about 10 hours ago
However - here it becomes weird - when testing the original regex rule (the first one, without the \u00A0 part) on the same string in an interactive visualiser (https://regexr.com/ for instance), there is a match:. - Source: dev.to / 8 months ago
Learned regex in the 90's from the Perl documentation, or possibly one of the oreilly perl references. That was a time where printed language references were more convenient than searching the internet. Perl still includes a shell component for accessing it's documentation, that was invaluable in those ancient times. Perl's regex documentation is rather fantastic. `perldoc perlre` from your terminal. Or... - Source: Hacker News / 10 months ago
I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches. One of the things I remember being difficult at the beginning was the subtle differences between implementations, like `^` meaning "beginning of line" in Ruby (and others) but meaning "beginning of... - Source: Hacker News / 10 months ago

Friedman's books are all great. All of them. But they don't work for everybody. If you can be relaxed and think of the interaction as play, they're very good. If you're feeling more of a "serious business" mindset, it can be hard to get in the groove of his style. There are a lot of jokes about food and encouragement to take breaks. If you can get into the learning as play mindset, I'd strongly encourage taking... - Source: Hacker News / 8 months ago
- pipe operator It compiles to either erlang or JavaScript, so I was able to jump right into building something fun with a new language. >I previously gave Clojure a try, that was a pretty good fit, but the JVM / ecosystem put me off. I felt similarly w/ leiningen (too much boilerplate) but was lisp-curious still so gave racket (https://racket-lang.org/) a try and appreciated the batteries included philosophy of... - Source: Hacker News / 9 months ago
Biased recommendation: Try racket https://racket-lang.org/ It's not pure functional, but the preferred style is to use mostly functional constructs. (But you can cheat when it get's too difficult or you need some extra speed.) (And you can download packages like Qi that enable a new language inside Racket that has more support for functional style.) (Most Schemes have a similar mostly-functional style, so you can... - Source: Hacker News / 10 months ago
