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 / 7 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 / 9 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 / 9 months ago

That's my go-to these days, but sometimes I like to see a diagram from this one: https://regexper.com I've just slowly learnt it by experimenting with it over the past few years. People have mostly mentioned matching, but I use it more for string manipulation. I'm still not as intermediate a programmer as I'd like to be, so it's great when I need to invert a design decision for example. A similar code structure in... - Source: Hacker News / 9 months ago

If it's a one-off regex to scrape some data and you verify the output, great. If it's to be used in an application and you don't understand it, that could be an issue. There's some great online tools to convert regex to railroad diagrams like https://regexper.com/ which I recommend if you don't understand some regex AI produced. Source: about 2 years ago
Not in plain English, but I find this tool useful if I have to read someone else's regex: https://regexper.com/. Source: about 2 years ago
