RegExRX

RegExRX is a regular‑expression development editor built on the PCRE library, allowing users to create patterns that are compatible with many language flavors. It provides tools for crafting, testing, and storing expressions, and includes functionality to copy the resulting patterns into languages such as Perl, Ruby, PHP, and Xojo. Sample pattern files are supplied to illustrate reusable expressions.

The application is offered as shareware for both macOS (10.10 or later) and Windows (7 or later), with a development build available for cautious testing. A companion Xojo module, M_RegExRX, enables RegExRX to be used as an external live editor within Xojo projects, and an example project demonstrates integration.

Targeted at both novice and professional developers who need a dedicated environment for regular‑expression work, RegExRX emphasizes cross‑language compatibility and ease of pattern reuse.
