@neustradamus #PCRE continues to be a misnomer; it’s a modified subset of #Perl #RegularExpressions with dozens of differences: https://pcre.org/current/doc/html/pcre2compat.html

It's not "(C)ompatible." Accept no substitutes: https://perldoc.perl.org/perlre

Spent half a day polishing complex #regexps in #vim . And they work too, but perl has a little different standard, so I'm basically stuck in grep -p punching a file until it works. As they say in #taoup , sometimes you just have to brute force prototype. #unix #bashcore #hobbylinguist #hobbytranslator

@Codely @drupler It helps to build your complicated #RegularExpressions in pieces and store them in separate variables. You can then test them in isolation and not be confused when you concatenate them together for your actual matching.

Both #PHP and #JavaScript also support named capture groups if you’re doing replacements. They’re a lot more readable.

Also, PHP’s #PCRE-based engine has a PCRE_EXTENDED flag that lets you add whitespace, newlines, and comments.
