Twisted 16.5 Release Announcement
by Amber "Hawkie" Brown 29 Oct '16

29 Oct '16

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.5! The highlights of this release are: - Deferred.addTimeout, for timing out your Deferreds! (contributed by cyli, reviews by adiroiban, theisencouple, manishtomar, markrwilliams) - yield from support for Deferreds, in functions wrapped with twisted.internet.defer.ensureDeferred. This will work in Python 3.4, unlike async/await which is 3.5+ (contributed by hawkowl, reviews by markrwilliams, lukasa). - The new asyncio interop reactor, which allows Twisted to run on top of the asyncio event loop. This doesn't include any Deferred-Future interop, but stay tuned! (contributed by itamar and hawkowl, reviews by rodrigc, markrwilliams) - twisted.internet.cfreactor is now supported on Python 2.7 and Python 3.5+! This is useful for writing pyobjc or Toga applications. (contributed by hawkowl, reviews by glyph, markrwilliams) - twisted.python.constants has been split out into constantly on PyPI, and likewise with twisted.python.versions going into the PyPI package incremental. Twisted now uses these external packages, which will be shared with other projects (like Klein). (contributed by hawkowl, reviews by glyph, markrwilliams) - Many new Python 3 modules, including twisted.pair, twisted.python.zippath, twisted.spread.pb, and more parts of Conch! (contributed by rodrigc, hawkowl, glyph, berdario, & others, reviews by acabhishek942, rodrigc, & others) - Many bug fixes and cleanups! - 260+ closed tickets overall. For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted <https://pypi.python.org/pypi/Twisted>> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads <http://twistedmatrix.com/trac/wiki/Downloads>>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-16.5.0/NEWS <https://github.com/twisted/twisted/blob/twisted-16.5.0/NEWS>>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted! Twisted Regards, Amber Brown (HawkOwl) PS: I wrote a blog post about Twisted's progress in 2016! https://atleastfornow.net/blog/marching-ever-forward/

Howdy all, I am pleased to announce the release of version 2.1.2 of the ‘python-daemon’ library. The current release is always available at <URL:https://pypi.python.org/pypi/python-daemon/>. Significant changes since the previous version ============================================== Additions: * Add a README document for the code base. Changes: * Migrate code project hosting to Pagure. Record the change of homepage URL in PyPI metadata. * Raise a warning that the ‘runner’ module is pending deprecation. This has been an unofficial example module from the beginning, and it will be removed in a future version. Bug Fixes: * Ensure custom types are part of the Python type hierarchy. * Avoid a circular dependency for the version string at install time. Thanks to Maarten van Gompel for the reproducible test case. What is the ‘python-daemon’ library? ==================================== ‘python-daemon’ is a Python library to implement a well-behaved Unix daemon process. -- \ “The best is the enemy of the good.” —Voltaire, _Dictionnaire | `\ Philosophique_ | _o__) | Ben Finney <ben(a)benfinney.id.au>

Cython 0.25 released
by Robert Bradshaw 25 Oct '16

25 Oct '16

I'm happy to announce the release of Cython 0.25 which has numerous new features and bug fixes. It is available at https://pypi.python.org/pypi/Cython We have also moved bug tracking from trac.cython.org to github issues. However, user support still remains at cython-users@, please refrain from filing issues until you have confirmed an actual bug. - Robert Features added -------------- * def/cpdef methods of cdef classes benefit from Cython's internal function implementation, which enables introspection and line profiling for them. Implementation sponsored by Turbostream (www.turbostream-cfd.com). * The distutils extension ``Cython.Distutils.build_ext`` has now been updated to use cythonize which properly handles dependencies. The old extension can still be found in ``Cython.Distutils.old_build_ext`` and is now deprecated. * Calls to Python functions are faster, following the recent "FastCall" optimisations that Victor Stinner implemented for CPython 3.6. See https://bugs.python.org/issue27128 and related issues. * The new METH_FASTCALL calling convention for PyCFunctions is supported in CPython 3.6. See https://bugs.python.org/issue27810 * C++ classes can now have typedef members. STL containers updated with value_type. * Support for bazel using a the pyx_library rule in //Tools:rules.bzl. * Initial support for using Cython modules in Pyston. Patch by Daetalus. * Dynamic Python attributes are allowed on cdef classes if an attribute ``cdef dict __dict__`` is declared in the class. Patch by empyrical. * Cython implemented C++ classes can make direct calls to base class methods. Patch by empyrical. * New directive ``cython.no_gc`` to fully disable GC for a cdef class. Patch by Claudio Freire. * Buffer variables are no longer excluded from ``locals()``. Patch by da-woods. * Building f-strings is faster, especially when formatting C integers. * for-loop iteration over "std::string". * ``libc/math.pxd`` provides ``e`` and ``pi`` as alias constants to simplify usage as a drop-in replacement for Python's math module. * Speed up cython.inline(). * Binary lshift operations with small constant Python integers are faster. * Some integer operations on Python long objects are faster in Python 2.7. * Support for the C++ ``typeid`` operator. Significant Bugs fixed ---------------------- * Division of complex numbers avoids overflow by using Smith's method. * Some function signatures in ``libc.math`` and ``numpy.pxd`` were incorrect. Patch by Michael Seifert. Other changes ------------- * The "%%cython" IPython/jupyter magic now defaults to the language level of the current jupyter kernel. The language level can be set explicitly with "%%cython -2" or "%%cython -3".

ANN: Abjad 2.19
by josiah oberholtzer 24 Oct '16

24 Oct '16

I'm pleased to announce that Abjad 2.19 is now available. Abjad is a Python API for Formalized Score Control Abjad helps composers build up complex pieces of music notation in an iterative and incremental way. Use Abjad to create symbolic representations of all the notes, rests, staves, tuplets, beams and slurs in any score. Because Abjad extends the Python programming language, you can use Abjad to make systematic changes to your music as you work. And because Abjad wraps the powerful LilyPond music notation package, you can use Abjad to control the typographic details of the symbols on the page. - Docs: http://abjad.mbrsi.org/ - GitHub: https://github.com/abjad/abjad - PyPI: https://pypi.python.org/pypi/Abjad/2.1 <https://pypi.python.org/pypi/Abjad/2.17>9 Details of the new release appear below. ------------ ## Improvements - [#740] Proofread ‘For beginners’ section of docs. Thanks @delucis! - [#741] LilyPond's log is displayed on LilyPond compilation error. - [#749] Added `LilyPondCommand` to Abjad's global namespace. - [#752] Taught `detach()` about different types of grace container. - [#753] Taught `Dynamics` about _sforzando_ dynamic names. - [#744] Refactoring and cleanup in `schemetools`. Thanks @ajyoon! - [#745] Reimplemented Abjad's repr, storage format and object templating system. - [#755, #760, #761, #763] Cleaned-up class member ordering via a new command-line script. Thanks @ajyoon! - [#766] Abjad's `ajv` looks for `.ajv` config files in $HOME, the current directory and any parent directory thereof. A [doctest] section can specify imports to be run at the beginning of each doctest in `ajv doctest` via an `imports` key. ## Changes - [#745] `AbjadObject`'s `_storage_format_specification` and `_repr_specification` properties are deprecated in favor of a new unified `_get_format_specification()` method. The old properties will no longer be supported in the next Abjad release: 2.20. ## Bugfixes - [#762] Improved interaction between chords and ties. Thanks @quesebifurcan! - [#764] `IOManager.open_file()` respects Abjad's config when opening MIDI files. Thanks @quesebifurcan! - [#767] Fixed edge-cases in Graphviz attribute-handling and append/extend behavior. - [#774] NamedPitch.invert() guards against errors from multiply-augmented or diminished intervals. ------------ Special thanks to 2.19 contributors @delucis (Chris Swithinbank), @ajyoon (Andrew Yoon) and @quesebifurcan (Fredrik Wallberg) on Github, and to Jeffrey Treviño for his constant and patient organization. ------------ For installation instructions, see http://abjad.mbrsi.org/installation.html. We hope you enjoy!

Open source and Cross platform Python Editor
by don.jayamanne＠gmail.com 23 Oct '16

23 Oct '16

Hi Everyone, I'm the author of a Python extension for the open source, MIT licensed and cross platform Visual Studio Code Editor (https ://code.visualstudio.com/). This is developed using nodejs and python, MIT licensed running on all major OS (OS X, Linux and Windows). The major features include: - Auto complete (intellisense) - Code navigation - Linting (mypy, pep8, pylint, flake8, etc) - Unit tests (pytest, nose, unittest) - Jupyter (IPython) - Debugging (django, flask, remote debugging, docker, multi threads, django templates, SSH, etc) - Code formatting (autopep8, yapf) - Refactoring, - Snippets and more Please note, this is open source and MIT licensed. This isn't meant to be a competitor to IDEs like PyCharm, instead is a lightweight and cross platform alternative (editor). I'm looking for some assistance in improving the capabilities of this extension (adding more features), looking for feedback suggestions and any help in maintaining it as well. More information here: - https://marketplace.visualstudio.com/items?itemName=donjayamanne.python - https://github.com/DonJayamanne/pythonVSCode
