Because I need it to match specifically to that pattern. There is other CSV text in the string that I need it to NOT match against when not wrapped in parens.

I'm not good enough at regex for this, sorry. My inclination would be to regex between first open and close parentheses and then split the result on comma. That might be more expensive than a repeated capture group, which I think is what you want.

EDIT: thought on your problem a bit more.

You're saying there could be "(73245q0987q03498trq09ew8r)" that you'd want to ignore and "(132352345029q348029384,bob)" that you'd want because it contains that comma?

There's a possibility of two types of inputs:

A,B,C,D,E,F

and

(A,B,128)

Basically I needed a regex that would match line 1 but not line 2 and vice versa.

But, it's fine, I got everything working. Basically used a regex that matches the parens string, then just manually remove the parens and split off the ','.

So, what I suggested

I would be curious if one regex would work and if it would even be the ideal solution from a performance standpoint. I was surprised to learn that Python, for example, doesn't support repeated capture group natively.

Nice, cool as fuck list.

Beats snot out of most of the boring ass shit I did for 90% of all my years in banking finance gaming and other IT industry software put together. Gotta be honest, even though I disliked govt bureaucracy the most, it was all right, and I never worked in defense (and anything really cool). The for profit industry was often much much worse in terms of efficiency (especially banking and finance, where what lurked beneath surface was VERY illegal, outright thievery as opposed to *just* inefficiency that I found in govt), it was just better and craftily hidden. Every job comes with some baggage, and lots of various positive and negative trade-offs anywhere you go.

And remember if it wasnt for govt defense R&D(which some of you appear to be crapping on, even though youre in IT *boggle* ) you would not have ANY IT or silicon valley whatsoever. None, zero, zip. Govt thinks and plans long term where private for profit...... doesnt. It just gets to profit from hard work and decades long investments of govt funded R&D, pretending to innovate on the back of a fckton of govt funded research. Thats the way the system is designed and it works well, best in world by FAR. And you often need a TON of R&D long term success-failure cycles before someone else can finally come along and know how to commercialize it properly.

Yeah, what is super simple in Javascript, Java, or C# is ugly and a pain in the ass in C++. I'll be glad when I'm done with this course. I absolutely cannot stand working with this language.

Sounds like you're already done. The purpose of teaching C++ is to make you hate it and appreciate other languages.

I think it was Linus Torvalds that said C++ gives you just enough rope to hang yourself with. I have no problems with C, the language is good at what it's intended(low level and performance). C++, in attempts to stay modern, has grafted on lots of ugly constructs, keywords, and symbols. Recent standards have done a decent job of patching things up, but you're still left with some rather ugly history. Especially when you consider how reliant C++ is on third party libraries. You may use standard C++17, but your dependencies might not.

I program directly into 1's and 0's. Compilers are for pussies.

Oh, you meant bug free? I thought you meant preventing people getting ahold of your source.

Odd that Noodleface mentions Coverity, my employer makes a competing product.
