RE2/J
linear time regular expression matching in Java
RE2/J is a high-performance regular expression engine implemented in pure Java as a port of Google’s C++ RE2 library. Unlike traditional regex engines such as Java’s java.util.regex, PCRE, or Perl’s implementation—which rely on backtracking and can suffer from catastrophic exponential runtimes—RE2/J guarantees linear-time matching relative to input size. It achieves this efficiency by simulating all possible matches in a single pass using a nondeterministic finite automaton (NFA), ensuring predictable and safe performance even with complex patterns. ... -

Pify
Promisify a callback-style function
...It can promisify a single function or process the methods of an entire module automatically. This makes older Node.js callback APIs easier to use with async and await syntax. Developers can selectively include or exclude methods through names or regular-expression patterns. The library can return multiple callback values as an array when an API provides more than one successful result. It also supports APIs that do not follow the conventional error-first callback pattern. Additional options allow the module's main function to remain untouched and permit use of a custom Promise implementation. -

JSVerbalExpressions
JavaScript Regular expressions made easy
...This method will not be accessible from outside the source file since VerEx() returns an instance of the class rather than the class itself. sanitize is a static method on the VerbalExpression class. However, it is also exposed as VerEx().sanitize. Enabling control multi-line matching would cause the expression to not look for matches beyond the first line. -

libvcr
A C++ library for managing configuration files via regular expressions
This library is supposed to be used in your C++ programs for managing simple Unix configuration files like /etc/hosts. The library allows to create default configuration, read the configuration file, validate each found option or value with C++ std::regex, automatically remove incorrect options and even merge several configurations with predefined priorities for each option. So it may be useful in programs which use several configuration files. For an extra example of the library usage see... -
