Hi All! I'd like to announce that I've implemented the new POSIX-2024 specification of the ERE regular expression. The software distribution is dedicated to the public domain, and I hope people can use it for any purpose including cross-checking between implementations, as well as the standard specification.
The implementation is posted at GitHub: https://github.com/dannyniu/librematch Thank you for your attention. DannyNiu/NJF.
