ANN: PyQwt-5.1.0 released

What is PyQwt ( http://pyqwt.sourceforge.net ) ?

- it is a set of Python bindings for the Qwt C++ class library which
  extends the Qt framework with widgets for scientific and engineering
  applications.   It provides a 2-dimensional plotting widget and
  various widgets to display and control bounded or unbounded floating
  point values.

- it requires and extends PyQt, a set of Python bindings for Qt.

- it supports the use of PyQt, Qt, Qwt, and optionally NumPy or SciPy
  in a GUI Python application or in an interactive Python session.

- it runs on POSIX, Mac OS X and Windows platforms (practically any
  platform supported by Qt and Python).

- it plots fast: fairly good hardware allows a rate of 100,000
points/second. (PyQwt with Qt-3 is faster than with Qt-4).

- it is licensed under the GPL with an exception to allow dynamic
linking with non-free releases of Qt and PyQt. 

The most important new features of PyQwt-5.1.0 are:
- support for Qwt-5.1.0.
- support for PyQt-4.4.2 and SIP-4.7.6.
- support for Qt-4.4.
- the CartesianDemo.py, MaskedDataDemo.py, PickerDemo.py examples.

The most important bug fixes in PyQwt-5.1.0 are:
- fixed QwtPicker::stateMachine() to allow for subclassing of QwtPicker

ANN: equivalence 0.1

Equivalence is a class that can be used to maintain a partition of
objects into equivalence sets, making sure that the equivalence
properties (reflexivity, symmetry, transitivity) are preserved. Two
objects x and y are considered equivalent either implicitly (through a
key function) or explicitly by calling merge(x,y).

Get it from pypi: http://pypi.python.org/pypi/equivalence/

Example
=======
Say that you are given a bunch of URLs you want to download and
eventually process somehow. These urls may contain duplicates, either
exact or leading to a page with the same content (e.g. redirects,
plagiarized pages, etc.). What you'd like is identify duplicates in
advance so that you can process only unique pages. More formally, you
want to partition the given URLs into equivalence sets and pick a
single representative from each set.

Getting rid of identical URLs is trivial. A more general case of URLs
that can be easily identified as duplicates can be based on some
simple regular expression based heuristics, so that for instance
'http://python.org/doc/' and 'www.python.org/doc/index.html' are
deemed equivalent. For this case you may have a normalize(url)
function that reduces a URL into its "stem" (e.g. 'python.org/doc')
and use this as a key for deciding equivalence.

This is fine but it still leaves quite a few URLs that cannot be
recognized as duplicates with simple heuristics. For these harder
cases you may have one or more "oracles" (an external database, a page
comparison program, or ultimately a human) that decides whether pages

ANN: Sydebar 1.0 - A browser sidebar generator for Python documentation

Content-Type: text/plain; charset=UTF-8; format=flowed

Content-Transfer-Encoding: quoted-printable

I am pleased to announce the first release of Sydebar, a browser sidebar =

generator for Python documentation. For the impatient, sample outputs=20

for all Python versions ever released can be found here:

   http://c-space.org/download/Sydebar/samples/

The program generates a single, self-contained XHTML file for a specific =

Python documentation URL, which can be local or remote. The generated=20

file is loaded into the sidebar of some popular browsers (tested on=20

Firefox and Opera, Mozilla should work as well), and presents a tabbed=20

interface with one page for each of the following documentation sections:=

  * Tutorial

  * Language reference

  * Library reference

  * Python/C API

  * Extending and embedding

  * Global module index

Each page shows a collapsible tree of chapters, with links opening the=20

corresponding section in the main browser pane. The global module index=20

features an incremental search functionality with fast keyboard navigatio=

n.

Moreover, a search page allows performing searches on various subsets of =

python.org (specific parts of the website, PEPs, newsgroups, PyPI and=20

the issue tracker).

The documentation and PyPI entry can be found here:

   http://c-space.org/software/Sydebar.html

   http://pypi.python.org/pypi/Sydebar

I would like to mention that Sydebar was inspired by python-sidebar from =

Daniel Lundin at Edgewall Software, and even though I didn't borrow any=20

code from there, the layout does bear quite some resemblance.

Feedback is very welcome.

Thanks for reading!

Shed Skin (restricted) Python-to-C++ Compiler 0.0.28

Hi all,

I have just released Shed Skin 0.0.28, with the following changes.
Thanks to those mentioned for helping out!

- basic 'socket' support (Michael Elkins)
- support for os.{popen3, popen4} under UNIX (Jaroslaw Tworek)
- support for time.strptime under Windows (David Marek)
- options for changing output dir, disabling annotation (Dave Tweed)
- support for 'cmp' and 'reverse' arguments of 'sorted' and 'list.sort'
- fixes for cross-module default arguments
- important fixes for type inference and inheritance
- restore compatibility with Python 2.3
- many minor bugfixes

I would really like to receive more bug reports. Please try out the
new version, and let me know about any problems.

With the socket support, 15 common modules are now largely supported.
For a 0.1 release, I'd really like to have support for one more
module: datetime. Thanks to the GHOP, there is a type model already
(lib/datetime.py), so we only still need a C++ implementation..

Thanks,
Mark Dufour.

setuptools_bzr 1.2


I'm happy to announce the setuptools_bzr 1.2 plugin for Python's  
setuptools.  This allows setuptools to find your Python package files  
kept under the Bazaar revision control system.  setuptools_bzr 1.2  
should be compatible with Bazaar 1.5.

This version fixes bug #237652 which prevented it from working  
correctly with loomified branches.  It also adds an environment  
variable to force use of the command line bzr(1) even if bzrlib can be  
found.

setuptools_bzr 1.2 is available in egg and source tarball format on  
the Python Package Index (a.k.a. Cheeseshop):

	http://pypi.python.org/pypi/setuptools_bzr/1.2

To use the plugin, just modify your setup() function in setup.py like  
so:

setup(...
   setup_requires = [
       'setuptools_bzr',
       ],
   ...)

The project home page is on Launchpad:

	https://launchpad.net/setuptoolsbzr

Enjoy,
-Barry
