cx_Oracle 6.0b1
by Anthony Tuininga 18 Apr '17

18 Apr '17

What is cx_Oracle? cx_Oracle is a Python extension module that enables access to Oracle Database for Python 2.x and 3.x and conforms to the Python database API 2.0 specifications with a number of enhancements. Where do I get it? https://oracle.github.io/python-cx_Oracle The easiest method to install cx_Oracle 6.0b1 is via pip as in python -m pip install cx_Oracle --pre Note that the --pre option is required since this is a prerelease. What's new? By far the most important update is the transition to ODPI-C ( https://github.com/oracle/odpi) which means that cx_Oracle can now be built without Oracle Client header files or libraries and that at runtime cx_Oracle can adapt to Oracle Client 11.2, 12.1 or 12.2 libraries without needing to be rebuilt. This also permits the use of binary wheels for the first time which will make installation much simpler than before. The full release notes can be read here: http://cx-oracle.readthedocs.io/en/6.0b1/releasenotes.html#version-6-0-beta… Please provide any feedback via GitHub issues ( https://github.com/oracle/python-cx_Oracle/issues).

Crowdfunding campaign for new config system in qutebrowser
by Florian Bruhin 18 Apr '17

18 Apr '17

Hi, I'm the main developer of qutebrowser, a keyboard-focused vim-like web browser, built using PyQt: https://www.qutebrowser.org/ Like last year, I'd love to spend my summer holidays working full-time on qutebrowser again! This is why I started another crowdfunding - this time with the goal of ripping out some of its oldest code (the configuration) and replacing it with something much more sane - something which has been planned for a long time already. You can find more details here: https://www.kickstarter.com/projects/the-compiler/qutebrowser-v10-with-per-… Florian -- http://www.the-compiler.org | me(a)the-compiler.org (Mail/XMPP) GPG: 916E B0C8 FD55 A072 | http://the-compiler.org/pubkey.asc I love long mails! | http://email.is-not-s.ms/

wxPython 4.0.0a1
by Robin Dunn 17 Apr '17

17 Apr '17

Announcing wxPython 4.0.0a1 --------------------------- https://pypi.python.org/pypi/wxPython/4.0.0a1 I'm pleased to announce that wxPython's Project Phoenix has made it's public debut as wxPython 4.0.0a1, available from PyPI. Don't let the fact that it is marked as an "alpha" release scare you away. It is an alpha simply because this is the **first** in several ways: * It's the first real release of Phoenix, which is built on a different foundation than Classic wxPython was. * It's the first wxPython release intended to be fully available from PyPI and buildable/installable by pip on all of the supported platforms. * It's the first release for Python3 (binaries for 3.5 and 3.6 are provided, and building for 3.4 is still possible as well). In addition, Python 2.7 is also supported from the same codebase, with binaries available. * The wheel files are fully self-contained and relocatable on the supported platforms, so they are installable in virtual environments without needing to be able to find specific versions of the wxWidgets shared libraries (or others) at fixed locations elsewhere in the file-system. * And as with most alphas, there are still a few things that are not finished or polished yet. But even with all that, many people have been using the pre-release snapshots of Phoenix for quite a while now, and it has been relatively stable and solid for them. What is wxPython? ----------------- wxPython is a cross-platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. Supported platforms are Microsoft Windows, Mac OS X and macOS, and Linux or other unix-like systems with GTK2 or GTK3 libraries. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. What is wxPython Phoenix? ------------------------- wxPython's Project Phoenix is a new from-the-ground-up implementation of wxPython, created with the intent of making wxPython “better, stronger, faster than he was before.” In other words, this new implementation is focused on improving speed, maintainability and extensibility of wxPython, as well as removing most of the cruft that had accumulated over the long life of Classic wxPython. The project has been in development off and on, mostly behind the scenes, for many years. For the past few years automated snapshot builds have been available for those adventurous enough to try it, and many people eventually started using the snapshots in their projects, even for production releases. While there are still some things on the periphery that need to be completed, the core of the new wxPython extension modules which wrap the wxWidgets code has been stable for a long time now. Due to some things being cleaned up, reorganized, simplified and dehackified wxPython Phoenix is not completely backwards compatible with wxPython Classic. This is intended. In general, however, the API differences tend to be minor and some applications can use Phoenix with slight, or even no modifications. In some other cases the correct way to do things was also available in Classic and it's only the wrong way that has been removed from Phoenix. For more information there is a Migration Guide document available at: https://wxpython.org/Phoenix/docs/html/MigrationGuide.html The new wxPython API reference documentation, including all Python-specific additions and customizations, and docs for the wx.lib package, is located at: https://wxpython.org/Phoenix/docs/html/main.html -- Robin Dunn Software Craftsman http://wxPython.org

ANN: Eliot 1.0, logging for distributed and complex systems
by Itamar Turner-Trauring 16 Apr '17

16 Apr '17

Do you need to understand a complex application? Most logging systems simply tell you some disjointed facts that you need to work hard to turn into a story. In contrast, Eliot provides structured, action-oriented logging: it tells you who did what and when, and whether it succeeded or failed. Eliot logs tell a story, of actions causing other actions. Release 1.0 is the result of over 3 years of development, and real-world usage of Eliot in many distributed applications. To learn more about Eliot I recommend reading the introduction: http://eliot.readthedocs.io/en/1.0.0/introduction.html -- Itamar Turner-Trauring

Grako 3.21.0
by Juancarlo Añez 14 Apr '17

14 Apr '17

Grako 3.21.0 ========== - Name all _"info"_ as `...Info`, make them classes that descend from `namedtuple`, have `__slots__ = ()`. Move them to module `infos`. - Status information during parsing is now routed through `logging.getLogger("grako")`. - Methods in `objectmodel.Node` that require an `infos.ParseInfo` will now raise `exceptions.NoParseInfo` if parse information is not available for the node. - There were broken links in the documentation after the repository was moved from /apalala/ to /neogeny/ on Bitbucket. Grako ===== Grako (for grammar compiler) is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python. https://pypi.python.org/pypi/grako/3.21.0 -- Juancarlo *Añez* mailto:apalala@gmail.com tel:+58(414)901-2021 <0414-9012021> skype:juancarloanez

[ANN] txkube 0.1.0
by Jean-Paul Calderone 10 Apr '17

10 Apr '17

Hello all, I'm pleased to announce the first release of txkube, a Twisted-based library for interacting with Kubernetes using the HTTP API. This release supports several of the most commonly used basic Kubernetes objects, including Services, ConfigMaps, Deployments, ReplicaSets, and Pods. While Kubernetes has many, many more object kinds, this collection of kinds already supports a very useful set of interactions. Here is an example of txkube usage, taken from the README: from __future__ import print_function from twisted.internet.task import react from txkube import v1, network_kubernetes_from_context @react def main(reactor): k8s = network_kubernetes_from_context(reactor, u"minikube") client = k8s.client() d = client.list(v1.Namespace) d.addCallback(print) return d You can download txkube from PyPI <https://pypi.python.org/pypi>. You can contribute to its development on GitHub <https://github.com/LeastAuthority/txkube>. Thanks to Least Authority Enterprises <https://leastauthority.com/> for sponsoring this development.
