[baseline 0.2.1] Easy String Baseline
by Dan Gass 29 Mar '20

29 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)

[RELEASE] ACTION REQUIRED: Python 3.8.0b4 now available for testing
by Łukasz Langa 30 Aug '19

30 Aug '19

It's time for the last beta release of Python 3.8. Go find it at: https://www.python.org/downloads/release/python-380b4/ <https://www.python.org/downloads/release/python-380b4/> This release is the last of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0c1, the first release candidate, currently scheduled for 2019-09-30. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker as soon as possible. Please note this is the last beta release, there is not much time left to identify and fix issues before the release of 3.8.0. If you were hesitating trying it out before, now is the time. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0c1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. That beta phase is coming to an end. Please test now. Please keep in mind that this is a preview release and its use is not recommended for production environments. Acknowledgments Many developers worked hard for the past four weeks to squash remaining bugs, some requiring non-obvious decisions. Many thanks to the most active, namely Raymond Hettinger, Steve Dower, Victor Stinner, Terry Jan Reedy, Serhiy Storchaka, Pablo Galindo Salgado, Tal Einat, Zackery Spytz, Ronald Oussoren, Neil Schemenauer, Inada Naoki, Christian Heimes, and Andrew Svetlov. 3.8.0 would not reach the Last Beta without you. Thank you! - Ł

cx_Freeze 6.0
by Anthony Tuininga 29 Aug '19

29 Aug '19

What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 3.5 or higher. For Python 2.7, use version 5. More information can be found at the web site: https://anthony-tuininga.github.io/cx_Freeze What's new? cx_Freeze 6.0 adds support for Python 3.7 and makes use of a number of improvements in Python 3. A lot of small improvements and bug fixes were made. The full release notes can be read here: https://cx-freeze.readthedocs.io/en/latest/releasenotes.html#version-6-0-au… . I want to thank Marcelo Duarte in particular for his help. Without him this release would have taken even longer than it already has and contained far fewer improvements and bug fixes! To install, use the following command: python -m pip install cx_Freeze --upgrade

28 Aug '19

I am happy to announce Guppy-PE 0.1.11 Guppy-PE is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specification Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source. The main news in this release: Contains notes and check that this package is only for Python2. A version for Python3 is recommended and is available here: https://github.com/zhuyifei1999/guppy3 License: MIT The project homepage is on GitHub: https://svenil.github.io/guppy-pe/ Enjoy, Sverker Nilsson
