[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)

Hello all, I'm very happy to announce the release of pyo 1.0.1, available for python 2.7, 3.5, 3.6, 3.7 and 3.8. Pyo is a Python module written in C to help real-time digital signal processing script creation. It provides a complete set of classes to build audio softwares, compose algorithmic musics or simply explore audio processing.It is available for Windows, macOS and linux. It is released under the LGPL 3 license. Official web site: http://ajaxsoundstudio.com/software/pyo/ pyo's documentation: http://ajaxsoundstudio.com/pyodoc/ Latest sources and bug tracker: https://github.com/belangeo/pyo The package is now uploaded to pypi.org and can be installed (for 32-bit or 64-bit) under MacOS, Windows and linux with pip. Just run the command: python -m pip install pyo For all the details and how to uninstall version prior to 1.0.0, see this page in the documentation: http://ajaxsoundstudio.com/pyodoc/download.html Bug Fixes: - Audio server falls back to playback-only mode if jack server has no input ports. - Fixed setting value of ControlSlider from national keyboard layout. - Fixed segfault when CallAfter's callback results in deleting itself. - Fixed tkinter font size on MacOS (issue #163). New features: - Added a clear() method to Mixer object to delete all inputs at once. - Added new object: Binaural, 3D stereo spatialization. - Added a DC blocker inside the feedback loop of Harmonizer object. - Added setChannelNames(names) method to Spectrum and Scope objects. - Added beatToDur(beat, bpm) function. Events framework (new framework to sequence events): Set of tools to generate sequence of events. The purpose of the Event framework is to allow the user to generate a sequence of events with as few as possible parameters to specify. The Events object is the heart of the framework. An Events object computes parameters, generally designed with event generator objects, builds the events and plays the sequence. See the Events framework examples in the documentation for different use cases. - EventScale: Constructs a list of pitches according to its arguments. - EventGenerator: Base class for all event generators. - EventKey: An EventGenerator that allow to retrieve the value of another parameter. - EventSeq: Plays through an entire list of values many times. - EventSlide: Plays overlapping segments from a list of values. - EventIndex: Plays values from a list based on a position index. - EventMarkov: Applies a Markov algorithm to a list of values. - EventChoice: Plays values randomly chosen from a list. - EventDrunk: Performs a random walk over a list of values. - EventNoise: White, pink or brown noise generator. - EventCall: Calls a function, with any number of arguments, and uses its return value. - EventConditional: Executes one generator or the other depending on the result of a condition. - Events: Sequencing user-defined events to form musical phrases. Expr API: - let statment can now store a complex number. - Expr now can handle multiple input sources. - Expr now can generate multiple output signals. - constants (pi, twopi, e, sr) can be used without braces. New example categories: - How to use OSC with pyo - Utilities - Events framework - Evaluating prefix expression Olivier Belanger belangeo(a)gmail.com http://olivier.ajaxsoundstudio.com/ ---- <P><A HREF="http://ajaxsoundstudio.com/software/pyo/">Pyo 1.0.1</A> - short Python DSP library.

ANN: evolutions 0.8.1
by arobert＠interstitiality.net 23 Nov '19

23 Nov '19

Announcing the release of evolutions 0.8.1 Evolutions is a new Python 3 tool for managing relational database schema evolution and data migration, modeled on the Scala/Java play-evolutions library (https://www.playframework.com/documentation/2.7.x/Evolutions). It employs a minimalist approach supporting only linear history and pure SQL migrations that works and stays out of your way in development and production environments. Application framework agnostic. This release is feature complete but beta status. Not recommended for production. We will release 1.0 once there has been enough field use to make us confident that bugs have been flushed out and the tool is proven suitably robust.

This releasee, 3.9.0a1 is the first of six planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2020-05-18) and, if necessary, may be modified or deleted up until the release candidate phase (2020-08-10). Please keep in mind that this is a preview release and its use is not recommended for production environments. Major new features of the 3.9 series, compared to 3.8 Many new features for Python 3.9 are still being planned and written. Among the new major new features and changes so far: PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>. (Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know <mailto:lukasz@python.org>.)
