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.}

%description -n python3-google-re2

A drop-in replacement for the re module.

It uses RE2 under the hood, of course, so various PCRE features (e.g.

backreferences, look-around assertions) are not supported. See

https://github.com/google/re2/wiki/Syntax for the canonical reference, but

known syntactic ”gotchas” relative to Python are:

  • PCRE supports \Z and \z; RE2 supports \z; Python supports \z,

    but calls it \Z. You must rewrite \Z to \z in pattern strings.

Known differences between this module’s API and the re module’s API:

  • The error class does not provide any error information as attributes.

  • The Options class replaces the re module’s flags with RE2’s options as

    gettable/settable properties. Please see re2.h for their documentation.

  • The pattern string and the input string do not have to be the same type.

    Any str will be encoded to UTF-8.

  • The pattern string cannot be str if the options specify Latin-1 encoding.
