TRE is described as 'Lightweight, robust, and efficient POSIX compliant regexp matching library with some exciting features such as approximate (fuzzy) matching' and is an app in the development category. There are five alternatives to TRE for Linux, Mac, Windows, Self-Hosted and FreeBSD. The best TRE alternative is Perl Compatible Regular Expressions, which is both free and Open Source. Other great apps like TRE are Hyperscan, nregex, RE2 and Oniguruma.
The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE has its own native API as well as a set of wrapper functions that correspond to the POSIX regular expression API.
Hyperscan is a high-performance multiple regex matching library. It follows the regular expression syntax of the commonly-used libpcre library, but is a standalone library with its own C API. Hyperscan uses hybrid automata techniques to allow simultaneous matching of large...
A DFA based Regex engine that supports submatches. Built with Nim (programming language). Benchmarks show nregex is up to 7 times faster than Perl Compatible Regular Expressions.
RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library with wrappers for many languages including Perl, Python, Erlang and more.
Oniguruma is a modern and flexible regular expressions library. It encompasses features from different regular expression implementations that traditionally exist in different languages.
