Fast, safe, thread-friendly regular expressions library
Branch: CURRENT,
Version: 0.99nb20230213,
Package name: re2-0.99nb20230213,
Maintainer: asauRE2 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.
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. RE2 uses
automata theory to guarantee that regular expression searches
run in time linear in the size of the input. RE2 implements
memory limits, so that searches can be constrained to a fixed
amount of memory. RE2 is engineered to use a small fixed C++
stack footprint no matter what inputs or regular expressions it
must process; thus RE2 is useful in multithreaded environments
where thread stacks cannot grow arbitrarily large.
On large inputs, RE2 is often much faster than backtracking
engines; its use of automata theory lets it apply optimizations
that the others cannot.
