ANN: calf 0.3.1
by Isaac To Nov. 9, 2019

Nov. 9, 2019

Hello all, I'm glad to announce the first public release of calf, 0.3.1: https://pypi.org/project/calf/0.3.1/ About ===== calf: Command Argument Loading Function for Python Calf lets you remove all your command argument parsing code, at least for simple cases. Only the implementation function is left, with initialization code that uses calf to call this function. The command argument parser is configured with a proper docstring, and perhaps some annotations (argument type) and default values for the parameters. In other words, stuffs that you would write anyway. The docstring can be written in Google, Sphinx, epydoc or Numpy style, and the design is that it is easy to swap the parsing function with yours. In fact, you can customize such a wide range of characteristics of calf, that you can treat it as a slightly restricted frontend to the ArgumentParser under the hood. Used in this way, you can treat calf as a cute way to configure argparse. This package shamelessly stole a lot of ideas from plac, but hopes to be more focused on creating comfortable command line interfaces rather than becoming a Swiss knife for programs with text-only user interface. <python-announce(a)python.org>

Pythran 0.9.4 - Hollsent
by Serge Guelton Nov. 6, 2019

Nov. 6, 2019

Hi folks, It's always a pleasure to announce a Pythran release, and here we go for a version bump! Short reminder: Pythran is an ahead-of-time compiler for scientific Python, with a focus on high-level numerical kernels, parallelism and vectorisation. Here is a simple kernel example, with a pythran annotation. Note that this kernel is still Python-compatible (from https://stackoverflow.com/questions/50658884): #pythran export euclidean_distance_square(float64[1,:], float64[:,:]) import numpy as np def euclidean_distance_square(x1, x2): return -2*np.dot(x1, x2.T) + np.sum(np.square(x1), axis=1)[:, np.newaxis] + np.sum(np.square(x2), axis=1) The Pythran package is available on PyPI, Github and Conda https://pypi.org/project/pythran/ https://anaconda.org/conda-forge/pythran https://github.com/serge-sans-paille/pythran Packages exist for archlinux and Fedora, they'll probably be updated soon :-) The interested reader can have a look to the changelog for details https://pythran.readthedocs.io/en/latest/Changelog.html Most notably, this release provides support for Python 3.7 and Python 3.8, as well as the ability to use clang-cl as a (better) backend compiler for Windows. Huge thanks to all contributors: paugier Anubhab Haldar Jean Laroche polo and bug reporters: paugier nbecker gdementen mgirardis MordicusEtCubitus Dapid piotrbartman m-romanov slayoo martibosch jeanlaroche

Discontinuing the pymssql Project
by Randy Syring Nov. 6, 2019

Nov. 6, 2019

I believe it's become necessary to discontinue the pymssql project. Pymssql is a dbapi2 drive for Microsoft SQL server. Full Announcement: https://github.com/pymssql/pymssql/issues/668 > Thank you to everyone who has contributed to pymssql over the years. > Unfortunately, I believe it's time to discontinue pymssql. It provides > an incredible amount of utility to those of us that need to connect to > MSSQL from Python. But, as a project, it has failed to attract enough > interest/talent/funding to maintain it. > > Why discontinue it and not let someone else maintain it? We've tried > over the years. See #516 > <https://github.com/pymssql/pymssql/issues/516>. We have got a few > people drop by to help occasionally, but nothing sustained enough to > feel like transfer of the project was warranted. > > I had always hoped my consulting business would be able to help > maintain the library for clients that use it. But there is too much > work here for us to tackle that doesn't really benefit our client's > usage and we transitioned to PyODBC earlier this year. > > I'm also concerned that if I simply abandon the project a bad actor > could gain control and start installing nasty stuff on what I am sure > is a lot of corporate servers. > > It's my hope that by discontinuing this project better solutions will > be developed and/or adopted to take it's place. > > > Other Related Issues > > * Proposal to discontinue pymssql in favor of pyodbc #477 > <https://github.com/pymssql/pymssql/issues/477> > * Maintainers Needed - Apply Within #516 > <https://github.com/pymssql/pymssql/issues/516> > * Finding grants/funding for pymssql development #621 > <https://github.com/pymssql/pymssql/issues/621> > > > Alternatives > > * pyodbc <https://github.com/mkleehammer/pyodbc>: Microsoft backed > o But see: https://github.com/level12/sqlalchemy_pyodbc_mssql > * ctds <https://github.com/zillow/ctds>: by Zillow > > > Interested in Taking Over? > > Just fork pymssql and start your own project. Gain momentum, show > progress, and I'd be happy to link to your project from here. > > > Next Steps > > I'm going to leave this issue open for suggestions on how best to > deprecate/discontinue pymssql as a project. I'm sure there will be > some who will suddenly be very interested in helping. I won't be > considering those requests at this point. If you want to help, see > above about forking. > > At the end of November, 2019 I'm going to Archive this GH repository > which will make it read-only. > > I'll also need to figure out how to deprecate packages on PyPI so that > people installing know the project is being discontinued. > *Randy Syring* Husband | Father | Redeemed Sinner /"For what does it profit a man to gain the whole world and forfeit his soul?"

by Chris Warrick Nov. 2, 2019

Nov. 2, 2019

On behalf of the Nikola team, I am pleased to announce the immediate availability of Nikola v8.0.3. This release fixes a few bugs, including a notable one with galleries not working on mobile. What is Nikola? =============== Nikola is a static site and blog generator, written in Python. It can use Mako and Jinja2 templates, and input in many popular markup formats, such as reStructuredText and Markdown — and can even turn Jupyter Notebooks into blog posts! It also supports image galleries, and is multilingual. Nikola is flexible, and page builds are extremely fast, courtesy of doit (which is rebuilding only what has been changed). Find out more at the website: https://getnikola.com/ Downloads ========= Install using `pip install Nikola`. Changes ======= Features -------- * Add Friulian translation by aoanla * Add ``extra_header`` and ``extra_footer`` blocks to templates (Issue #3291) * Add ``REST_FILE_INSERTION_ENABLED`` config option to enable or disable reST external file inclusion directives (Issue #3311) Bugfixes -------- * Support Markdown v3.x (Issue #3173) * Fix galleries in Firefox Mobile and when resizing window (Issue #3258) * Output ``<code>`` tag for double backticks in reST (Issue #3276) * Fully switch to HTML5 writer for reST (Issue #3276, getnikola/plugins#294) * Make ipynb listings work again * Correctly link to listings with spaces in their names * import_wordpress plugin doesn't require anymore a translation and can use nikola's default if none provided * Wordpress+qtranslate import (--qtranslate option) now works with more recent versions of plugins from the qtranslate family (namely qtranslate-X) * Fixed a wordpress import exception when image metadata has floats formated with ',' instead of '.'
