Can you add bindings for python? It would be great!

Thanks

There are some here http://github.com/facebook/pyre2 (although I haven't tested 
them)

It says:
 "Unlike most automata-based engines, RE2 implements almost all the common Perl and
PCRE features and syntactic sugars. It also finds the leftmost-first match, the 
same
match that Perl would, and can return submatch information. The one significant
exception is that RE2 drops support for backreferences¹ and generalized 
zero-width
assertions, "
 So, Comparing to Python or Perl's regexps syntax and latest features, what other
syntax/features haven't been implemented in re2 yet (besides backreference and
generalized zero-width assertions)? 
Is there a black-list for that?

The next sentence after what you've quoted from the home page reads:

    The syntax page gives full details.

Click on the syntax page link.

Yup, that's a 'white-list', but a black one with the list of all features have 
not been supported/implemented yet is much easy to see, re2-users can 
keep those points in mind and do not make subtle mistakes while using re2.
And also, it helps others developers that interested with re2 to make an effort 
on those missing features. That's helpful.

@delianxu: Maybe it doesn't show up correctly in your web browser,
but the list lists all the Python and Perl syntax I am aware of too.
The things that RE2 does not support are grayed out, as it says at
the top of the page.

@stefano.rivera: this binding has no findall() and finditer()... :-(
