safe-regex2

safe-regex2 is a utility for detecting potentially catastrophic exponential-time regular expressions by limiting the star height to 1. It is useful for ensuring that regex patterns do not lead to performance issues in applications. This package is a fork of the original safe-regex and is not a comprehensive checker.
