This is proof that regex even confuses the bots.
I still don’t understand regex at all
I recommend using https://regex101.com/
It explains all parts of your regex and highlights all matches in your example text. I usually add a comment to a regex101 playground if I use a regex in code.

I disagree. I found it to be incredibly useful when I knew what regex was and that I needed it, but I couldn’t piece together a single string with it.
The plural of regex is regrets.
My guess is, that someone started with a small share of features to find a simple solution for the problem, but the complexity of the problem got waaaay out of hand.
Regexes are actually used in formal computer science (if that’s the right term), i.e. “proof that this and that algorithm won’t deadlock” or something like that.
They’re actually really elegant and can cover a lot. But you’ll have to learn them by using them.
For the purpose of algorithm verification, the final and/or pushdown automaton or probably sometimes even Turing Machines are used, because they are easier to work with. “Real” regular expressions are only nice to write a grammar for regular languages which can be easily interpreted by the computer I think. The thing is, that regexs in the *nix and programming language world are also used for searching which is why there are additional special characters to indicate things like: “it has to end with …” and there are shortcuts for when you want that a character or sequence occurs
- at least once,
- once or never or
- a specified number of times back to back.
In “standard” regex, you would only have
- () for grouping,
- * for 0 or any number of occurances (so a* means blank or a or aa or …)
- + as combining two characters/groups with exclusive or (in programming, a+ is mostly the same as aa* so this is a difference)
- and sometimes some way to have a shortcut for (a+b+c+…+z) if you want to allow any lower case character as the next one
So there are only 4 characters which have the same expressive power as the extended syntax with the exception of not being able to indicate, that it should occur at the end or beginning of a string/line (which could even be removed if one would have implemented different functions or options for the tools we now have instead)
So one could say that *nix regex is bloated /s
Nobody does.

Could have been worse. Could have been an Error in Excess.
Regex’s are not something you need AI for as there are already tools that explain them for you. Use regexr.com or a similar tool.

You can do it. You too can pluralize without an apostrophe.

Thanks for pointing that out, it’s a bad habit I’ve picked up!
____ are not something you need AI for as there are already tools that explain ____ for you. Use Wikipedia or a similar tool.
I don’t agree that AI has no uses, you just have to know when to use it. There are multiple times I have scoured documentation and official forums of a niche tool to few results only to ask ChatGPT and get far closer to my goal in 2 minutes than I did in 30. I know the AI has to be getting that info from somewhere, but if Google, Reddit, and a forum search can’t find it then I am sorry but I am going to ask an AI.
Yeha, also anything else has plenty of books and internet content on them so you really don’t need AI for those too.
You have a problem. You decide to use regex to solve it. Now you have two problems.
