I'm pleased to announce the release of Cython 0.22. This release has numerous bug fixes and several new features. It is is available in the usual locations:
http://cython.org/release/Cython-0.22.tar.gz https://pypi.python.org/pypi/Cython/0.22 Happy Coding! Robert Features added -------------- * C functions can coerce to Python functions, which allows passing them around as callable objects. * C arrays can be assigned by value and auto-coerce from Python iterables and to Python lists (and tuples). * Extern C functions can now be declared as cpdef to export them to the module's Python namespace. Extern C functions in pxd files export their values to their own module, iff it exists. * Anonymous C tuple types can be declared as (ctype1, ctype2, ...). * PEP 479: turn accidental StopIteration exceptions that exit generators into a RuntimeError, activated with future import "generator_stop". See http://legacy.python.org/dev/peps/pep-0479/ * Looping over ``reversed(range())`` is optimised in the same way as ``range()``. Patch by Favian Contreras. Bugs fixed ---------- * Mismatching 'except' declarations on signatures in .pxd and .pyx files failed to produce a compile error. * Failure to find any files for the path pattern(s) passed into ``cythonize()`` is now an error to more easily detect accidental typos. * In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be interpreted as non-contiguous by CPython, which could trigger a CPython bug when copying data from them, thus leading to data corruption. See CPython issues 12834 and 23349. Other changes ------------- * Preliminary support for defining the Cython language with a formal grammar. To try parsing your files against this grammar, use the --formal_grammar directive. Experimental. * ``_`` is no longer considered a cacheable builtin as it could interfere with gettext. * Cythonize-computed metadata now cached in the generate C files. * Several corrections and extensions in numpy, cpython, and libcpp pxd files. -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
