[baseline 0.2.1] Easy String Baseline
by Dan Gass 30 Mar '20

30 Mar '20

I am please to announce the availability of the "baseline" package. This tool streamlines creation and maintenance of tests which compare string output against a baseline. It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability for human review. Docs: https://baseline.readthedocs.io/en/latest/ PyPi: https://pypi.org/project/baseline/ Repo: https://github.com/dmgass/baseline License: MIT With Regards, Dan Gass (dan.gass at gmail) *********** Quick Start *********** Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as ``fox.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected Run ``fox.py`` and observe that the ``assert`` raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the miscompared value. When the interpretter exited, the tool saved the updated source file but changed the file name to ``fox.update.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected After reviewing the change with your favorite file differencing tool, accept the change by either manually overwriting the original file or use the ``baseline`` command line tool to scan the directory for updated scripts and accept them: .. code-block:: shell $ python -m baseline * Found updates for: fox.py Hit [ENTER] to update, [Ctrl-C] to cancel fox.update.py -> fox.py Run ``fox.py`` again and observe the ``assert`` does not raise an exception nor is a source file update generated. If in the future the test value changes, the ``assert`` will raise an exception and cause a new source file update to be generated. Simply repeat the review and acceptance step and you are back in business! <P><A HREF="https://baseline.readthedocs.io/en/latest/"> baseline 0.2.1</A> - Easy String Baseline (07-Jun-18)

Nikola v8.0.1 is out!
by Chris Warrick 30 Sep '18

30 Sep '18

On behalf of the Nikola team, I am pleased to announce the immediate availability of Nikola v8.0.1. Some bugs were fixed; more importantly, we pinned down the Markdown package version due to incompatibilities. 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`. (Python 3-only since v8.0.0.) Changes ======= * Not compatible with Markdown 3.x yet, this release pins the requirement down to 2.x (until we get 3.x support done) Features -------- * Make URL displayed by ``nikola auto`` and ``nikola serve`` clickable (Issue #3166) Bugfixes -------- * Pandoc compiler was passing deleted argument (Issue #3171) * Make ``nikola version --check`` work again (Issue #3170) * Set logging level for reST to warning in order to limit noise * Fix docinfo removal for sites that use reST docinfo metadata (Issue #3167)

24 Sep '18

Dear EuroPython'istas, We are in preparations of our venue RFP for the EuroPython 2019 edition and are asking for your help in finding the right locations for us to choose from. If you know of a larger venue - hotel or conference center - that can accommodate at least 1400 attendees, please send the venue details to board(a)europython.eu. We will then make sure to include them in our RFP once we send it out. The more venues we gather to reach out to, the better of a selection process we can guarantee, which in return, will ultimately result in a better conference experience for everybody involved. When sending us venue suggestions, please make sure to provide us with the following: name and URL of the venue, country and city, as well as the contact details of the sales person in charge of inquiries (full name, email and phone). We were planning to start the RFP process in the coming days, so please make sure you send us your recommendations as soon as possible. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !
