ANN: SUMMON 1.8.5 Released: 2D Visualization prototyping and scripting
by rasmus 04 Feb '08

04 Feb '08

SUMMON 1.8.5 SUMMON is a python extension module that provides rapid prototyping of 2D visualizations. By heavily relying on the python scripting language, SUMMON allows the user to rapidly prototype a custom visualization for their data, without the overhead of a designing a graphical user interface or recompiling native code. By simplifying the task of designing a visualization, users can spend more time on understanding their data. SUMMON is designed to be a fast interface for developing interactive scene graphs for OpenGL. Although python libraries already exist for accessing OpenGL, python is relatively slow for real-time interaction with large visualizations (trees with 100,000 leaves, sparse matrices with a million non-zeros, etc.). Therefore, with SUMMON all real-time interaction is handled with compiled native C++ code (via extension module). Python is only executed in the construction and occasional interaction with the visualization. This arrangement provides the best of both worlds. SUMMON 1.8.4 comes with the following features: * a demo large sparse matrix visualizer (ideal for visualizing clusterings) * a demo tree visualizer * Python C++ extension module * Fast OpenGL graphics * Drawing arbitrary points, lines, polygons, text with python scripting * Binding inputs (keyboard, mouse, hotspots) to any python function * Separate threads for python and graphics (allows use of python prompt and responsive graphics at the same time) * Transparently handles graphics event loop, scrolling, zooming, text layout (auto-clipping, scaling, alignment), and click detection; allowing you to focus on viewing your data * SVG output (also GIF/PNG/JPG/etc via ImageMagick) * Cross-platform (Linux, Windows, OS/X) * And lots of examples for how to prototype your own custom 2D visualizations Web site and download: http://people.csail.mit.edu/rasmus/summon/

AVC 0.5.0 released
by f.pollastri＠inrim.it 04 Feb '08

04 Feb '08

Announcing AVC 0.5.0 ---------------------------- Webpage: http://avc.inrim.it/ What is AVC? ----------------- AVC is a multiplatform, fully automatic, live connection among graphical interface widgets and application variables for the python language. AVC supports in a uniform way the most popular widget toolkits: GTK, Qt3, Qt4, Tk, wxWidgets. AVC is a python module that can be imported by any python application. The display and the control of some application data through a GUI (Graphical User Interface) is a central problem in GUI programming, it absorbs a relevant part of the programming effort. AVC makes this programming very easy, far more easy than traditional solutions based on MVC (Model View Controller). Features ----------- * Fully transparent widget-variable connections * Automatic connection by matching widgets and variables names * No design pattern, no application redesign, no widget toolkit dependent code. * Multiple widget toolkits support: GTK, Qt3, Qt4, Tk, wxWidgets. * Full compatibility and support for Glade, Qt Designer, Visual Tcl and wxGlade interface design tools. * Widgets support: button, check button, combo box, entry, label, radio button, slider, spin button, status bar, text view/edit, toggle button. * Variable types support: boolean, integer, float, string, list, tuple. * Multiple widgets to one variable connection * Dual update timing of variable value views: immediate or periodic. * Testing printout logging activity with selectable verbosity * Python module written in pure python * Free software ( GNU GPL license ) Changelog -------------- AVC 0.5.0 released 4-Feb-2008 * Extended label widget output formatting to support generic python objects and to have a fallback to the standard python string representation (str()) when there is no formatting string or the formatting string is not valid. * New examples: a label formatting example program for each supported toolkit. * New examples: a programmatic version (GUI generated by program instructions) of the spin button/box/control example for each supported toolkit. * Added testing capability: activity report printout with selectable verbosity level. * Rewrited the widget abstraction layer: improved code structure, more compact, better separation among widget toolkit dependent code in AVC bindings and in AVC core code. * Anticipated the test for supported widget from coget creation (Coget.__init__()) to connections detector (_bind()): more efficient. AVC 0.4.0 released 15-Dec-2007 * Added support for wxWidgets widget toolkit, widgets: button, bitmap button, check button, choice, combo box, radio box, slider, spin control, static text, status bar, text control, toggle button. AVC 0.3.0 released 30-Sep-2007 * Added support for TK widget toolkit, widgets: button, check button, entry, label, radio button, scale, spin box, text. * Fixed input from Qt4 QdoubleSpinBox. * Fixed wrong type of formatting string for Qt3 and Qt4 label widget. * Added control type casting to string returned by entry widget. * New web site structure, user documentation moved from one html page to "User Manual" in different formats: pdf, html. AVC 0.2.0 released 30-Jan-2007 * Added new widgets: combo box, slider, status bar (GTK only), text view/edit. AVC 0.1.0 released 10-Jan-2007 * First release.

ANN: cssutils 0.9.5a3 (the namespace release ;)
by Christof Hoeke 03 Feb '08

03 Feb '08

what is it ---------- A Python package to parse and build CSS Cascading Style Sheets. main changes since 0.9.5a2 -------------------------- for full details for 0.9.5a3 see the relevant CHANGELOG: http://cssutils.googlecode.com/svn/tags/TAG_0.9.5a3/CHANGELOG.txt A few (minor) non-backwards compatible changes have been made, please see http://cssutils.googlecode.com/svn/tags/TAG_0.9.5a3/documentation/migrate.t… for migration help. 0.9.5a3 - **API CHANGE: Refactored and fixed namespace handling** Aim was to prevent building invalid style sheets. Therefor namespaces must be checked e.g. when adding a new ``Selector`` etc. This is probably not fixed for all cases but much better now than before. - added ``CSSStyleSheet.namespaces`` which is a mapping of ``prefix: namespaceURI`` and mirrors all namespaces as defined in @namespace rules. New Namespaces may also be set here as well as prefixes changed. - if more than one ``CSSNamespaceRule`` with the same ``namespaceURI`` is set only the last one will be kept. The ``prefix`` of that rule is used. - ``CSSNamespaceRule.namespaceURI`` is readonly now, it can only be set in the constructor (needed to prevent an invalid sheet when changing this uri) - Namespaces used in a Selector or SelectorList or even a CSSStyleRule while these are not attached to a CSSStyleSheet (which would contain the necessary CSSNamespaceRules) are kept internally. All these classes accept for parameter ``selectorText`` (or ``cssText`` for CSSStyleRule) a tuple of ``(string-to-parse, dict-of-namespaces)`` now while not attached to a style sheet. If attached ``dict-of-namespaces`` is ignored as the namespaces of the relevant style sheet are used. If you need to set e.g. a new selector within a yet undefined namespace, set the namespace in the style sheet first simply by setting e.g. ``sheet[prefix] = namespaceURI`` - removed ``CSSStyleSheet.prefixes`` - removed ``Selector.prefixes`` - **API CHANGE**: ``parentRule`` and ``parentStyleSheet`` of all CSS rules are now readonly to prevent building illegal style sheets. - **API CHANGE**: Changed order of constructor parameters for ``CSSStyleDeclaration``. Named parameters SHOULD be used anyway but be careful if you used ordered ones here! * **FEATURE**: ``CSSStyleSheet`` and ``CSSMediaRule`` are iterable now. Both iterate on their ``cssRules``. * **FEATURE**: added convinience method ``CSSStyleSheet.add(rule)`` which behaves exactly like ``.insertRule(rule, inOrder=True)``. So rules are added to the approprite position in a style sheet. E.g a namespace rule if put after any @import but before other rules like style or font-face rules. * **FEATURE**: added parameter ``inOrder=False`` to method ``CSSStyleSheet.insertRule`` which inserts a given rule to its proper hierarchy. Parameter ``index`` is ignored in this case but the resulting index is properly returned. + **BUGFIX**: ``CSSMediaRule.insertRule`` setting with a rule string fixed + **BUGFIX**: ``*.parentStyleSheet`` and ``*.parentRule`` where * is any CSSRule is properly set now + **BUGFIX**: ``CSSStyleDeclatation.getPropertyPriority(p)`` returns ``important`` (without the ``"!"``!) or the empty string now (see http://dev.w3.org/csswg/cssom/#the-cssstyledeclaration). Same goes for ``Property.priority`` which is not in CSSOM but cssutils only. (``Property._normalpriority`` has been removed, the normalized value that was available here is now in ``Property.priority``. The literal priority value is available in ``Property.literalproperty`` now (analog to ``Property.literalname``). All these values probably should not be used by client code anyway but may be helpful when using CSS hacks.) Note: CSSValue, CSSValueList, and CSSPrimitiveValue and the relevant methods/properties Property.cssValue and CSSStyleDeclaration.getPropertyCSSValue are more or less DEPRECATED and will probably be replaced with interfaces defined in CSSOM. For now use the properties and methods that handle values as simple strings, e.g. ``Property.value``. As the aforementioned classes are not hardly that useful anyway this should not be a big problem but please beware if you use or have used them. If you think this a bad idea please let me know! license ------- cssutils is published under the LGPL. download -------- for download options for see http://cthedot.de/cssutils/ cssutils needs Python 2.4 or higher (tested with Python 2.5 on Vista only) bug reports (via Google code), comments, etc are very much appreciated! thanks, Christof
