history
Project history and usage
rgxg is a C library and command-line tool that generates extended regular expressions for ranges and network address blocks.
Project history
rgxg, expanded by its project as ReGular eXpression Generator, was written and maintained by Hannes von Haugwitz as both a C library and a command-line program. Version 0.1.2 was released on 12 April 2020, and the project publishes signed source releases and Git tags.
Adoption history
The official site records downstream packages in Debian, Ubuntu, Alpine Linux, the Arch User Repository, NixOS, FreeBSD, and Homebrew.
How it is used
Users generate expressions matching decimal or hexadecimal number ranges, IPv4 CIDR blocks, and IPv6 CIDR blocks, then pass those expressions to another matching or validation tool. Releases and repository tags can be verified with the maintainer's published OpenPGP key.
Why package nerds care
rgxg generates difficult boundary-sensitive regular expressions rather than asking users to maintain them by hand. Its dual library and CLI interfaces make the same generator useful in C programs and shell tooling.
