Summary : C++ fast alternative to backtracking RE engines
URL : http://github.com/google/re2/
License : BSD
Description : RE2 is a C++ library providing a fast, safe, thread-friendly alternative to
: backtracking regular expression engines like those used in PCRE, Perl, and
: Python.
:
: Backtracking engines are typically full of features and convenient syntactic
: sugar but can be forced into taking exponential amounts of time on even small
: inputs.
:
: In contrast, RE2 uses automata theory to guarantee that regular expression
: searches run in time linear in the size of the input, at the expense of some
: missing features (e.g back references and generalized assertions).
