PyRegex is an application designed to help developers quickly and easily build, test, and debug regular expressions (regex). It provides an intuitive, graphical user interface that allows users to construct a regex pattern, test it against a text string, and view the results. The app also includes an advanced editor that allows users to easily tweak their regex patterns and see the results in real-time. Additionally, PyRegex has a library of pre-made regex patterns, and users can access over 800 pre-made regex patterns for commonly used tasks. This library can be used to quickly and efficiently solve text-processing problems.
Visual REGEXP was discontinued for the last time in 2006.
