DESCRIPTION
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. This is the source code repository for RE2, a regular expression library. There is a fair amount of documentation (including code snippets) in the re2.h header file. Unless otherwise noted, the RE2 source files are distributed under the BSD-style license found in the LICENSE file. In POSIX mode, RE2 accepts standard POSIX (egrep) syntax regular expressions. In Perl mode, RE2 accepts most Perl operators. The only excluded ones are those that require backtracking (and its potential for exponential runtime) to implement. These include backreferences (submatching is still okay) and generalized assertions. The Syntax page documents the supported Perl-mode syntax in detail. The default is Perl mode. The constructor takes an optional second argument that can be used to change RE2's default options.
