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.

***********
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!

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

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.
License: BSD
Package: https://pypi.org/project/evolutions/0.8.1/
Development: https://github.com/arobertn/evolutions
Go get it here: https://www.python.org/downloads/release/python-390a1/ <https://www.python.org/downloads/release/python-390a1/>
This is an early developer preview of Python 3.9
Python 3.9 is still in development. 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>.)
The next pre-release of Python 3.9 will be 3.9.0a2, currently scheduled for 2019-12-16.
