regex-engine

An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.

A full-featured regex engine in pure Go based on the .NET engine

The regex-centric, fast lexical analyzer generator for C++ with full Unicode support. Faster than Flex. Accepts Flex specifications. Generates reusable source code that is easy to understand. Introduces indent/dedent anchors, lazy quantifiers, functions for lex/syntax error reporting, and more. Seamlessly integrates with Bison and other parsers.

A low level regular expression library that uses deterministic finite automata.
