Kleingrep
Kleingrep is a regular expression engine, providing a library and command-line tool written in Go.
It aims to provide a more featureful engine, compared to the one in Go's standard library, while retaining some semblance of efficiency.
The engine does not use backtracking, relying on the NFA-based method described in Russ Cox's articles. As such, it is immune to catastrophic backtracking.
It also includes features not present in regexp, such as lookarounds and backreferences.
Syntax
The syntax is, for the most part, a superset of Go's regexp. A full overview of the syntax can be found here.
