Regex Isn't Hard (2023) (timkellogg.me)
Regex gets a bad reputation for being very complex. That’s fair, but I also think that if you focus on a certain core subset of regex, it’s not that hard. Most of the complexity comes from various “shortcuts” that are hard to remember. If you ignore those, the language itself is fairly small and portable across programming languages.

Giving C++ std:regex a C makeover (nullprogram.com)
Suppose you’re working in C using one of the major toolchains — that is, it’s mainly a C++ implementation — and you need regular expressions. You could integrate a library, but there’s a regex implementation in the C++ standard library included with your compiler, just within reach. As a resourceful engineer, using an asset already in hand seems prudent. But it’s a C++ interface, and you’re using C instead of C++ for a reason, perhaps _to avoid dealing with C++_. Have no worries. This article is about wrapping [`std::regex`](https://en.cppreference.com/w/cpp/regex) in a tidy C interface which not only hides all the C++ machinery, but _utterly tames it_. It’s not so much practical as a potpourri of interesting techniques.
