ANN: PythonQwt 0.6.2
by Pierre Raybaut Aug. 9, 2020

Aug. 9, 2020

Hi all, I am pleased to announce that PythonQwt v0.6.2 has been released (https://github.com/PierreRaybaut/PythonQwt). This is a maintenance release, compatible with Python 2.7, 3.4-3.8, PyQt4 and PyQt5. The PythonQwt package is a 2D-data plotting library using Qt graphical user interfaces for the Python programming language. It is compatible with both PyQt4 and PyQt5 (PySide is currently not supported but it could be in the near future). The PythonQwt project was initiated to solve -at least temporarily (at the time...)- the obsolescence issue of PyQwt (the Python-Qwt C++ bindings library) which is no longer maintained. The idea was to translate the original Qwt C++ code to Python and then to optimize some parts of the code by writing new modules based on NumPy and other libraries. The PythonQwt package consists of a single Python package named qwt which is a pure Python implementation of Qwt C++ library with some limitations: efforts were concentrated on basic plotting features, leaving higher level features to the guiqwt library. The PythonQwt documentation with examples, API reference, etc. is available here: https://pythonqwt.readthedocs.io/en/latest/ Python package index page: https://pypi.org/project/PythonQwt/ -- Pierre Raybaut

[ANN] PyInstaller 4.0
by Hartmut Goebel Aug. 9, 2020

Aug. 9, 2020

Hello, on behalf of the PyInstaller development team I'm happy to announce PyInstaller 4.0. http://www.pyinstaller.org Thanks for all those who contributed questions, bug-reports or pull-requests. PyInstaller is in urgent need of funding to make future security fixes happen, see <https://github.com/pyinstaller/pyinstaller/issues/4404> for details. === Important Changes === Release 4.0 adds support for 3rd-party packages to provide PyInstaller hooks along with the package. This allows Maintainers of other Python packages to deliver up-to-date PyInstaller hooks as part of their package. See our sample project <https://github.com/pyinstaller/hooksample> for more information. PyInstaller uses this option itself to provide updated hooks much faster: Many hooks are moved into the new package pyinstaller-hooks-contrib <https://github.com/pyinstaller/pyinstaller-hooks-contrib>, which is updated monthly. This package is installed automatically when installing PyInstaller, but can also be updated independently. Finally, this version drops support for Python 2.7, which is end-of-life since January 2020.. The minimum required version is now Python 3.5. The last version supporting Python 2.7 was PyInstaller 3.6. The full changelog for this release can be found at: https://pyinstaller.readthedocs.io/en/v4.0/CHANGES.html === What it is === PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules. PyInstaller reads a Python script written by you. It analyzes your code to discover every other module and library your script needs in order to execute. Then it collects copies of all those files – including the active Python interpreter! – and puts them with your script in a single folder, or optionally in a single executable file. PyInstaller is tested against Windows, Mac OS X, and Linux. However, it is not a cross-compiler: to make a Windows app you run PyInstaller in Windows; to make a Linux app you run it in Linux, etc. PyInstaller has been used successfully with AIX, Solaris, and FreeBSD, but is not tested against them. === Help keeping PyInstaller alive === Maintaining PyInstaller is a huge amount of work. PyInstaller development can only continue if users and companies provide sustainable funding. Please consider recurring donations. See http://www.pyinstaller.org/funding.html for how to support PyInstaller. === Installation === PyInstaller can be installed from PyPi using pip install pyinstaller === Important Changes === The full changelog for this release can be found at: https://pyinstaller.readthedocs.io/en/v4.0/CHANGES.html === Feedback === We're eager to listen to your feedback on using PyInstaller: Bug tracker: https://github.com/pyinstaller/pyinstaller/issues Mailing list: http://groups.google.com/group/PyInstaller -- Schönen Gruß Hartmut Goebel Dipl.-Informatiker (univ), CISSP, CSSLP, ISO 27001 Lead Implementer Information Security Management, Security Governance, Secure Software Development Goebel Consult, Landshut http://www.goebel-consult.de Blog: http://www.goebel-consult.de/blog/warum-sie-nicht-perl-programmiern-sollten Kolumne: http://www.cissp-gefluester.de/2012-02-bring-your-own-life-glosse

ANN: guidata v1.7.7
by Pierre Raybaut Aug. 9, 2020

Aug. 9, 2020

Hi all, I am pleased to announce that `guidata` v1.7.7 has been released (https://github.com/PierreRaybaut/guidata). This is a maintenance release with a couple of bugfixes (compatibility with Spyder v4) -- guidata is compatible with Python 2.7, 3.4-3.8, PyQt4 and PyQt5. Based on the Qt GUI library (PyQt4, PyQt5, and mostly compatible with PySide), guidata is a Python library generating graphical user interfaces for easy dataset editing and display. It also provides helpers and application development tools for PyQt. guidata also provides the following features: * guidata.qthelpers: PyQt helpers * guidata.disthelpers: cx_Freeze/py2exe helpers (or how to build a self-consistent executable in three lines of code!) * guidata.userconfig: .ini configuration management helpers (based on Python standard module ConfigParser) * guidata.configtools: library/application data management * guidata.gettext_helpers: translation helpers (based on the GNU tool gettext) * guidata.guitest: automatic GUI-based test launcher * guidata.utils: miscelleneous utilities guidata has been successfully tested on GNU/Linux and Windows platforms. The `guidata` documentation with examples, API reference, etc. is available here: https://guidata.readthedocs.io/en/latest/ Python package index page: http://pypi.python.org/pypi/guidata/ -- Pierre Raybaut

Vulture 1.6
by Jendrik Seipp Aug. 7, 2020

Aug. 7, 2020

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: uses static code analysis * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * sorts unused classes and functions by size with ``--sort-by-size`` * supports Python 2.7 and Python 3.5+ News ==== * Differentiate between functions and methods (Jendrik Seipp, #112, #209). * Move from Travis to GitHub actions (RJ722, #211). Cheers Jendrik

Released logassert 5
by Facundo Batista Aug. 6, 2020

Aug. 6, 2020

I'm happy to bring you a new release of logassert, a simple logging assertion mechanism for Python unittests. Because we all know that we must test the logging calls in our programs, right? With `logassert` this is very easy. This new release brings the functionality of logassert as a pytest fixture, with totally renewed semantics (for "classic unittest" structures, logassert is not changing much, to be backwards compatibile). So, for pytest all you need to do is to declare `logs` in your test arguments (it works just like any other fixture), and then just check (using `assert`, as usual with *pytest*) if a specific line is in the logs for a specific level. See this example, with several log lines, and a specific assertion: logger.info("Starting system") places = ['/tmp/', '~/temp'] logger.debug("Checking for config XYZ in all these places %s", places) logger.warning("bad config XYZ") assert "bad config XYZ" in logs.debug See how the test failure message is super helpful: assert for regex 'bad config XYZ' check in DEBUG, failed; logged lines: INFO 'Starting system' DEBUG "Checking for config XYZ in all these places ['/tmp/', '~/temp']" WARNING 'bad config XYZ' You can install logassert from PyPI: https://pypi.org/project/logassert/ The project is in Github: https://github.com/facundobatista/logassert Interested on more detail about how this work? As I said above, you include the `logs` fixture and just assert. Example: def test_bleh(logs) (...) assert "The meaning of life is 42" in logs.debug Actually, the line you write is a regular expression, so you can totally do (in case you're not exactly sure which the meaning of life is): assert "The meaning of life is \d+" in logs.debug The indicated string is searched to be inside the log lines, it doesn't need to be exact whole line. If you want that, just indicate it as with any regular expression: assert "^The meaning of life is \d+$" in logs.debug In a similar way you can also express the desire to check if it's at the beginning or at the end of the log lines. **NOTE**: the message checked is the final one, after the logging system replaced all the indicated parameters in the indicated string. If you want to verify that a text was logged, no matter at which level, just do: assert "The meaning of life is 42" in logs.any_level To verify that some text was NOT logged, just juse the Python's syntax! For example: assert "A problem happened" not in logs.error If you don't like regexes just import `Exact` from `logassert` and wrap the string with that. For example, in this case the `..` means exactly two dots, no regex semantics at all: assert Exact("The meaning of life is ..") in logs.any_level If you need help, or have any question, or found any issue, please open a ticket [here](https://github.com/facundobatista/logassert/issues/new). Thanks in advance for your time. -- . Facundo Blog: http://www.taniquetil.com.ar/plog/ PyAr: http://www.python.org.ar/ Twitter: @facundobatista

Pythran 0.9.6 - talar tro
by Serge Guelton Aug. 1, 2020

Aug. 1, 2020

Hi folks, and sorry for the double posting if any, It's my pleasure to share with you the 0.9.6 release of Pythran, code-named talar-tro [0]. Pythran is a compiler for numerical kernels written in Python. It doesn't require much type information and its inputs are 100% compatible with the Python interpreter (but the other way around is not true!) More than 6 months have passed since last revision, so the changelog is a bit dense [1], but basically, that's the first release that only supports Python3 [2], I made quite a lot of changes in the expression engine and it comes with more supported numpy stuff, hopefully less bugs etc. As usual, it's available on Pypi, conda-forge and github :-) [0] https://br.wikipedia.org/wiki/Talar-tro [1] https://pythran.readthedocs.io/en/latest/Changelog.html [2] Is that even a feature?
