ANN: PyWavelets 1.0.0

[Gregory Lee]

Hello all,

We are pleased to announce the release of PyWavelets 1.0. We view this
version number as a milestone in the project's now more than a decade long
history.  It reflects that PyWavelets has stabilized over the past few
years, and is now a mature package which a lot of other important packages
depend on. A listing of those package won't be complete, but some we are
aware of are:

- `scikit-image `_ - image processing in Python
- `imagehash `_ - perceptual
image hashing
- `pyradiomics `_ - extraction of
Radiomics features from 2D and 3D images and binary masks
- `tomopy `_ - Tomographic Reconstruction
in Python
- `SpikeSort `_ - Spike sorting library
implemented in Python/NumPy/PyTables
- `ODL `_ - operator discretization library

This release requires Python 2.7 or >=3.5 and NumPy 1.9.1 or greater. The
1.0 release will be the last release supporting Python 2.7.  It will be a
Long Term Support (LTS) release, meaning that we will backport critical bug
fixes to 1.0.x for as long as Python itself does so (i.e. until 1 Jan 2020).

A summary of new features and lists of specific issues and pull requests
closed is available in the full release notes at:

forcallpy: embed Python, call Python scripts within Fortran programs

[Laurent Pointal]

Hello,

Here is an announce for people with main Fortran programs who need to 
call Python scripts and do not want to start another process each time. 
Forcallpy embeds the Python interpreter in your Fortran program and makes 
scalars or one dimensional arrays of numbers easy to transmit between the 
two languages. It automatically install numpy in the Python side (used by 
this library), and support Python multithreading.

Project git repository and bug tracking:

https://sourcesup.renater.fr/projects/forcallpy/

Documentation:

https://forcallpy.readthedocs.io/en/latest/

For an example, here is the Fortran demo program, without comments (more 
details in documentation about values transmission between Python and 
Fortran):

PROGRAM forcallpy_demo
  USE forcallpy
  USE, INTRINSIC :: iso_c_binding, ONLY: c_ptr, c_null_ptr, c_loc
 
  IMPLICIT NONE
  INTEGER :: coderr
  INTEGER :: intres

  DOUBLE PRECISION,DIMENSION(5),TARGET :: tabdbl;
  TYPE(c_ptr),DIMENSION(3) :: tabptr;
  DOUBLE PRECISION,DIMENSION(4),TARGET :: tabres;
 
  tabint(1:10) = (/ 3, 4, 5, 6, 7, 8, 9, 10, 11, 12  /)
  tabdbl(1:5) = (/ 10.1, 10.3, 10.5, 10.7, 10.9 /)
  tabptr(1:3) = (/ c_null_ptr, c_null_ptr , c_null_ptr  /)
  tabres(1:4) = (/ 0.0, 0.0, 0.0, 0.0 /)
  tabptr(2) = c_loc(tabdbl)
 
  CALL pyinit(register_sighandlers=1, print_errors=1, verbosity=0, &
 coderr=coderr)

  CALL pyrun_i4r8('print("result =",3 + 4 *  x)', x=3.6D0)
  CALL pyrun_i4r8('for i in range(3): print("This is a Python loop", i, 
"directly in fortran source.")')
  CALL pyrun_i4r8('import math')
  CALL pyrun_i4r8('print("Pi value is", math.pi)')
  CALL pyrun_i4r8('import sys'//NEW_LINE('a')//'sys.path.insert(0, ".")')
  CALL pyrun_i4r8('import forcallpy_demomodule')
  CALL pyrun_i4r8('print("Doc forcallpy:", forcallpy.__doc__)')
  CALL pyrun_i4r8('print("Namespace forcallpy:", dir(forcallpy)')
  intres = pyfct_i4r8_i4(&
"int(forcallpy_demomodule.a_function(a,b,c,x,av,zv,yw))", &

  CALL pysub_i4r8("print(1/0)")
  CALL pyrun_i4r8('forcallpy_demomodule.test_threading()')
  call sleep(10)
  CALL pyterm() 
END PROGRAM forcallpy_demo

[Release] Pyo 0.9.1 (Python dsp library)

[Olivier Bélanger]

Hello all,

I'm glad to announce the release of pyo 0.9.1, available for python
2.7, 3.5 and 3.6.

Pyo is a Python module written in C to help real-time digital signal processing
script creation. It is available for Windows, macOS and linux. It is released
under the LGPL 3 license.

For more info, downloads and other links, see the official web site:

http://ajaxsoundstudio.com/software/pyo/

The documentation:

http://ajaxsoundstudio.com/pyodoc/

For the latest sources and bug tracker:

https://github.com/belangeo/pyo


Bug Fixes:

- Fixed Server window's Interpreter field scrolling history on MacOS.

- Fixed crash when asking for more input or output channels than available.

- Fixed Compress output level when input's rms is above unity.

- Fixed phase shifting between the frequency bands of FourBand.

- On Windows, use 'directsound' as the default audio host (much more
  reliable than 'wasapi').


New features:

- Added getPrecision() function. Removed print statement when importing pyo.
  User should use getVersion() and getPrecision() functions if needed.

- E-Pyo: Added the ability to remove a project from the project tree.

- Added a new object: MultiBand, frequency splitter using Linkwitz-Riley
  crossover filters.
