Release of Pmw.1.3
by hulne000＠planet.nl 06 Aug '07

Subject: ANNOUNCE: Pmw megawidgets 1.3 Pmw megawidgets for Tkinter Version 1.3 Greg McFarlane <gregm(a)iname.com> http://pmw.sourceforge.net/ Serge Hulne shulne(a)planet.nl --oOo-- A new release of Pmw is out. This release makes Pmw compatable with recent releases of python and Tcl/Tk. This version of Pmw was tested against python 2.3, 2.4, 2.5 Tcl/Tk 8.4.2 and Blt 2.4z. Except for Blt, all tests pass. Blt seems to be more flacky than usual, with core dumps occuring in the Graph code. Since this is a problem in Blt (not Pmw), the Blt test script has been removed from the default Pmw test sequence. Several other bug fixes and improvements were made. See the change log for details. A setup.py script has been added in order to automate the installation of Pmw. To download Pmw or for more information, see the home page at http://pmw.sourceforge.net/ If you have any comments, enhancements or new contributions, please contact Serge (shulne(a)planet.nl) or me (gregm(a)iname.com) . ===================================================================== What is Pmw? Pmw is a toolkit for building high-level compound widgets, or megawidgets, constructed using other widgets as component parts. It promotes consistent look and feel within and between graphical applications, is highly configurable to your needs and is easy to use. It uses the Tkinter python library. Pmw consists of: - A few base classes, providing a foundation for building megawidgets. - A library of flexible and extensible megawidgets built on the base classes, such as buttonboxes, notebooks, comboboxes, selection widgets, paned widgets, scrolled widgets and dialog windows. - A lazy importer/dynamic loader which is automatically invoked when Pmw is first imported. This gives unified access to all Pmw classes and functions through the Pmw. prefix. It also speeds up module loading time by only importing Pmw sub-modules when needed. - Complete reference documentation, covering all classes and functions including all megawidgets and their options, methods and components. Helpful tutorial material is also available. - A test framework and tests for Pmw megawidgets. - A slick demonstration of the megawidgets. - An interface to the BLT busy, graph and vector commands. The interface to Pmw megawidgets is similar to basic Tk widgets, so it is easy for developers to include both megawidgets and basic Tk widgets in their graphical applications. In addition, Pmw megawidgets may themselves be extended, using either inheritance or composition. The use of the Pmw megawidgets replaces common widget combinations with higher level abstractions. This simplifies code, making it more readable and maintainable. The ability to extend Pmw megawidgets enables developers to create new megawidgets based on previous work.

tl.eggdeps 0.2.1
by Thomas Lotze 06 Aug '07

06 Aug '07

tl.eggdeps 0.2.1 has been released. The eggdeps tool reports dependencies between eggs in the working set. Dependencies are considered recursively, creating a directed graph. This graph is printed to standard output either as plain text, or as an input file to the graphviz tools. tl.eggdeps is released under the Zope Public License, version 2.1. The package is available from the Python package index as a source distribution and Python 2.4 and 2.5 eggs: <http://pypi.python.org/pypi/tl.eggdeps> You can access the source code repository at <https://svn.thomas-lotze.de/repos/public/eggdeps/>, or browse it using ViewCVS at <http://svn.thomas-lotze.de/svn-public/eggdeps/>. >From the documentation (see <http://www.thomas-lotze.de/en/software/eggdeps/readme.html>): Graph building strategies ------------------------- The dependency graph may be built following either of two strategies: :Analysing the whole working set: Nodes correspond exactly to the distributions in the working set. Edges corresponding to all conceivable dependencies between any active distributions are included, but only if the required distribution is active at the correct version. The roots of the graph correspond to those distributions no other active distributions depend upon. :Starting from one or more eggs: Nodes include all packages depended upon by the specified distributions and extras, as well as their deep dependencies. They may cover only part of the working set, as well as include nodes for distributions that are not active at the required versions or not active at all (so their dependencies can not be followed). The roots of the graph correspond to the specified distributions. Some information will be lost while building the graph: - If a dependency occurs both mandatorily and by way of one or more extras, it will be recorded as a plain mandatory dependency. - If a distribution A with installed extras is a dependency of multiple other distributions, they will all appear to depend on A with all its required extras, even if they individually require none or only a few of them. Reducing the graph ------------------ In order to reduce an otherwise big and tangled dependency graph, certain nodes and edges may be omitted. :Ignored nodes: Nodes may be ignored completely by exact name or regular expression matching. This is useful if a very basic distribution is a depedency of a lot of others. An example might be ``setuptools``. :Dead ends: Distributions may be declared dead ends by exact name or regular expression matching. Dead ends are included in the graph but their own dependencies will be ignored. This allows for large subsystems of distributions to be blotted out except for their "entry points". As an example, one might declare ``zope.app.*`` dead ends in the context of ``zope.*`` packages. :No extras: Reporting and following extra dependencies may be switched off completely. This will probably make most sense when analysing the working set rather than the dependencies of specified distributions. -- Thomas

ANN: doctest-mode 0.4
by Edward Loper 04 Aug '07

04 Aug '07

Announcing doctest-mode 0.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Webpage: http://www.cis.upenn.edu/~edloper/projects/doctestmode/ Walk-through: http://tinyurl.com/25bljc Subversion: https://python-mode.svn.sf.net/svnroot/python-mode/trunk/python-mode/ About doctest-mode ~~~~~~~~~~~~~~~~~~ "doctest-mode" is an Emacs major mode for editing text files that contain Python "doctest" examples. (Doctest is a testing framework for Python that emulates an interactive session, and checks the result of each command. For more information on doctest, see <http://docs.python.org/lib/module-doctest.html>). doctest-mode makes it easier to write and maintain doctest files, by providing: - Syntax highlighting of the prompts, source code, and expected output for each doctest example. - Editing support, including automatic indentation (similar to python-mode) and automatic prompt management. - Execution support, allowing you to run doctest directly from emacs, and examine the results in an output buffer. - Failure navigation, allowing you to quickly navigate between failed examples after you run doctest. - Output replacement, allowing you to easily update doctest examples with the correct output value. Improvements in Version 0.4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ - improved syntax highlighting. - doctest is now run asynchronously by default. - added support for older versions of doctest (pre-Python 2.4) - editing the doctest buffer no longer causes doctest-mode to lose track of the correspondence between examples in the doctest buffer and results in the *doctest-output* buffer. - numerous bug-fixes. - new command: doctest-execute-region (C-c |). - improved portability between different emacs versions. Tested on: * XEmacs 21.4 (patch 17) [Lucid] (i386-debian-linux, Mule) * GNU Emacs 21.3.1 (i386-mingw-nt5.1.2600) * GNU Emacs 22.0.50.1 (powerpc-apple-darwin8.3.0) * GNU Emacs 21.2.1 (powerpc-apple-darwin8.0) Licesnse ~~~~~~~~ Copyright (C) 2004-2007 Edward Loper This software is provided as-is, without express or implied warranty.
