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` or download tarballs on GitHub and PyPI: https://github.com/getnikola/nikola/releases/tag/v7.7.2 https://pypi.python.org/pypi/Nikola/7.7.2 Changes ======= Features - -------- * Warning about Python 2.7 deprecation (Issues #2121, #2122) * New ``jsonminify`` filter for minifying JSON files. * New ``xmlminify`` filter for minifying XML files. * New option ``FEED_PREVIEWIMAGE`` includes the ``post.meta.previewimage`` image in Atom and RSS feeds.

ANN: Eliot 0.9, the logging system with causality - now with journald support
by Itamar Turner-Trauring 08 Oct '15

08 Oct '15

Eliot 0.9 is out, with a new utility for pretty-printing log messages and native journald support [1]. You can now route Eliot logs to journald and when an error occurs easily find all logged actions that led up to that particular error, as opposed to most logging systems where this would involve reading all the logs and figuring out which ones apply and which to ignore. Most logging systems can tell you what happened; Eliot tells you _why_ it happened: $ python linkcheck.py | eliot-tree 4c42a789-76f5-4f0b-b154-3dd0e3041445 +-- check_links@1/started `-- urls: [u'http://google.com', u'http://nosuchurl'] +-- download@2,1/started `-- url: http://google.com +-- download@2,2/succeeded +-- download@3,1/started `-- url: http://nosuchurl +-- download@3,2/failed |-- exception: requests.exceptions.ConnectionError |-- reason: ('Conn aborted', gaierror(-2, 'Name unknown')) +-- check_links@4/failed |-- exception: exceptions.ValueError |-- reason: ('Conn aborted.', gaierror(-2, 'Name unknown')) And here's the code that generated these logs (eliot-tree [2] was used to render the output): import sys from eliot import start_action, to_file import requests to_file(sys.stdout) def check_links(urls): with start_action(action_type="check_links", urls=urls): for url in urls: try: with start_action(action_type="download", url=url): response = requests.get(url) response.raise_for_status() except Exception as e: raise ValueError(str(e)) check_links(["http://google.com"], ["http://nosuchurl"]) Interested?

First release of pytest-vw!
by Florian Bruhin 07 Oct '15

07 Oct '15

Hey, I'm happy to announce the first release of pytest-vw, a pytest plugin which makes failing test cases succeed in continuous integration tools. See https://github.com/The-Compiler/pytest-vw for more information. Of course, any similarities with a current event concerning (but not limited to) a multinational automobile manufacturer are purely coincidental. (In all seriousness: This was mainly to try the excellent cookiecutter[1] and cookiecutter-pytest-plugin[2] projects - it's also inspired by (read: a blatant ripoff of) PHPunit VW) [1] https://github.com/audreyr/cookiecutter [2] https://github.com/pytest-dev/cookiecutter-pytest-plugin [3] https://github.com/hmlb/phpunit-vw 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/

by Florian Bruhin 07 Oct '15

07 Oct '15

Hey, I'm happy to announce pytest 2.8.2 has been released. In case you wonder, pytest is a widely used mature test runner both for unit and functional test purposes in python. See http://pytest.org for documentation and examples. Among other things, this release fixes a regression introduced in 2.8.1 when using parametrize with encoded byte strings: - fix #1085: proper handling of encoding errors when passing encoded byte strings to pytest.parametrize in Python 2. Thanks Themanwithoutaplan for the report and Bruno Oliveira for the PR. - fix #1087: handling SystemError when passing empty byte strings to pytest.parametrize in Python 3. Thanks Paul Kehrer for the report and Bruno Oliveira for the PR. - fix #995: fixed internal error when filtering tracebacks where one entry was generated by an exec() statement. Thanks Daniel Hahler, Ashley C Straw, Philippe Gauthier and Pavel Savchenko for contributing and Bruno Oliveira for the PR. Thanks to all who contributed to this release, among them: Bruno Oliveira Demian Brecht Florian Bruhin Ionel Cristian Mărieș Raphael Pierzina Ronny Pfannschmidt holger krekel There are still some regressions open from 2.8, among them an issue when using objects with a custom __getattr__ with Python 2.6: https://github.com/pytest-dev/pytest/issues/1035 Fixes for those issues are in progress, and there hopefully will be a 2.8.3 release soon. Thanks for flying pytest and sorry for the turbulences! ;) 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/

by Mark Lutz 07 Oct '15

07 Oct '15

There is a new version of frigcal, a Python 3.X/tkinter desktop GUI calendar program. This version makes an install of the third-party Pillow (a.k.a. PIL) library optional for some combinations of image-file type and Python version; addresses incompatible changes in color names in the Tk 8.6 library underlying tkinter in Python 3.4 and later; and on Linux improves the behavior of modal dialogs and window icons.

fades 4 beta
by Facundo Batista 05 Oct '15

05 Oct '15

Hello all, We're glad to announce the PRE-release of fades 4. Yes, we're releasing fades 4 beta. fades, a FAst DEpendencies for Scripts, is a system that automatically handles the virtualenvs in the simple cases normally found when writing scripts or simple programs. It will automagically create a new virtualenv (or reuse a previous created one), installing the necessary dependencies, and execute your script inside that virtualenv. You only need to execute the script with fades (instead of Python) and also mark the required dependencies. More details here: https://github.com/PyAr/fades/ What's new in this release? - New option to use iPython as the interactive interpreter: --ipython (thanks Ariel Rossanigo) - Now it's possible to execute a program inside the virtualenv, with -x (thanks Ricardo Kirkner) For example, it's possible to create a project in Django without having Django installed in your system, doing: fades -d django -x manage startproject foo - Can execute fades as a Python's module (thanks Javi Mansilla) python3 -m fades <...etc...> - Dependencies can be specified in docstrings - If you want to fiddle with lower layers options, can send parameters to virtualend or pip. - We have a logo! - Now we run the fades tests using fades itself, no need to install anything previously - Other minor bugfixes and improvements To get it: As this is a beta release, just get it from the repository: https://github.com/PyAr/fades/ Once cloned, you can install it (classic "sudo python3 setup.py install") or just use it from that directory ("bin/fades"). Help / questions: - You can ask any question or send any recommendation or request to the mailing list. http://listas.python.org.ar/mailman/listinfo/fades - Also, you can open an issue here (please do if you find any problem!). https://github.com/PyAr/fades/issues/new Thanks in advance for your time! -- .
