pytypes 1.0 beta 4 has been released. https://github.com/Stewori/pytypes Beneath several bugfixes, the most notable new feature is a utility function for explicitly resolving forward references, e.g. of a manually defined type. Another significant improvement is proper support for tuple ellipses. The converter utility stubfile_2_converter, alias typestubs, was improved significantly. It can now be used to dump type info from a module (or other stubfile) into a stubfile, supporting type comments and ordinary type annotations as input or output. E.g. it can convert type comments from Python 2 code to an original Python 3 style stubfile and vice versa. pytypes is a toolbox for PEP-484 style typing, explicitly supporting Python >= 3.3, Python 2.7, Jython >= 2.7.1, PyPy 3. Its main features include: - Runtime typechecking - Auto-annotating code from runtime observations in form of stubfiles - Utility functions: * PEP 484 aware subtype and instance checking: is_of_type(obj, tp) and is_subtype(subtype, supertype) * get_type_hints that takes stubfiles and type comments into account - Typesafe method overriding - Pull type information from stubfiles or type comments into __annotations__ for use by other tools - all features smoothly work with OOP, i.e. methods, static methods, class methods, properties pytypes is still in beta phase. File issues as the occur. Help is welcome! Github: https://github.com/Stewori/pytypes/releases PyPI: https://pypi.python.org/pypi/pytypes License: Apache 2.0 Enjoy! -Stefan
