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

There are some alternatives like https://grep.app or https://sourcegraph.com/search if you want fast live search, but at the end of the day these are generally expensive services to provide, especially for free anonymous users, so you should probably at least accept that service providers can and do change things like this. You can also run something like your own copy of Zoekt and then ingest repositories on... - Source: Hacker News / 8 months ago

Https://grep.app/ has served me well for the last couple of years finding snippets for random APIs. But recently I found that certain strings from open-source projects suddenly yield no results. For example: VaultServiceTimeout from https://github.com/rajanadar/VaultSharp has no results for https://grep.app/search?q=VaultServiceTimeout. Is there some alternative service for this task that is up-to-date? - Source: Hacker News / about 1 year ago
