ANN: CAGE 1.1.3 -- A generic and fairly complete cellular automata simulation engine
by Erik Max Francis Oct. 6, 2003

Oct. 6, 2003

Summary A generic and fairly complete cellular automata simulation engine. Overview CAGE is a fairy generic and complete cellular automaton simulation engine in Python. It supports both 1D and 2D automata, a variety of prepackaged rules, and the concept of "agents" which can move about independently on the map for implementing agent behavior. CAGE comes with numerous examples of fully-functional CA systems, including Conway's Game of Life, Langton's self-reproducing automaton, Langton's "vants," and 1D automata rule explorers. It also comes with simple displayers (including a curses interface for 2D automata). Also included is a unique implementation of a finite state machine (ant.py). Note that CAGE is implemented entirely in Python, and due to its very generalized nature, is not designed for speed. It is sufficient to update a 80x24 Conway's Game of Life grid at a few times per second on a modern machine. CAGE is intended primarily as an education toolkit, rather than an industrial-strength CA simulator. Getting the software The current version of cage is 1.1.3. The software is available in a tarball here: http://www.alcyone.com/software/cage/cage-latest.tar.gz. The official URL for this Web site is http://www.alcyone.com/software/cage/. License This code is released under the LGPL. .... Release history [since 1.1] - 1.1.3; 2003 Oct 5. Fix AsynchronousAutomaton updating method; add a chain reaction demo; changed license to LGPL. - 1.1.2; 2002 Nov 4. Workaround for reported crashes on some Linux systems in either curses or the Python curses glue layer. - 1.1.1; 2002 Jul 23. The Conway automaton inadvertently defaulted to "high life" instead of the standard rule. -- Erik Max Francis && max(a)alcyone.com && http://www.alcyone.com/max/ __ San Jose, CA, USA && 37 20 N 121 53 W && &tSftDotIotE / \ Life imitates art far more than art imitates life. \__/ Oscar Wilde

ANN: DOMForm 0.0.1a released
by jjl＠pobox.com Oct. 5, 2003

Oct. 5, 2003

http://wwwsearch.sourceforge.net/DOMForm/ This is the first release. There are many known bugs, and interfaces will change. Most of the bugs are in the JavaScript support. The ClientForm work-alike stuff is relatively stable (but see the entities and select_default bugs listed in the known bugs list on the web page). Feedback is welcome, but do check the list of known bugs on the web page. Requires Python 2.3 and PyXML 0.8.3 (earlier versions may work, but are untested). Currently mxTidy is required (I may switch to uTidylib at some point). The spidermonkey Python module is required if you want JavaScript interpretation. DOMForm is a Python module for web scraping and web testing. It knows how to evaluate embedded JavaScript code in response to appropriate events. DOMForm supports both the ClientForm HTML form interface and the HTML DOM level 2 interface (note that ATM the DOM is written to an out-of-date version of the specification, and has some hacks to get it to work with 'DOM as deployed'). The ClientForm interface makes it easy to parse HTML forms, fill them in and return them to the server. The DOM interface makes it easy to get at other parts of the document, and makes JavaScript support possible. The ability to switch back and forth between the two interfaces allows simpler code than would result from using either interface alone. DOMForm is partly derived from several third-party libraries. The JavaScript support currently depends on Mozilla's GPLed spidermonkey JavaScript interpreter (which is available separately from Mozilla itself), and a Python interface to spidermonkey. Simple example: from urllib2 import urlopen from DOMForm import ParseResponse response = urlopen("http://www.example.com/") window = ParseResponse(response) window.document # HTML DOM Level 2 HTMLDocument interface forms = window._htmlforms # list of objects supporting ClientForm.HTMLForm i/face form = forms[0] assert form.name == "some_form" domform = form.node # level 2 HTML DOM HTMLFormElement interface control = form.find_control("some_control") # ClientForm.Control i/face domcontrol = control.node # corresponding level 2 HTML DOM HTMLElement i/face doc.some_form._htmlform # back to the ClientForm.HTMLForm interface again doc.some_form.some_control._control # ClientForm.Control interface again response = urlopen(form.click()) # domform.submit() also works John

ANN: Story Talker 0.1.0.0
by Gary Cramblitt Oct. 4, 2003

Oct. 4, 2003

Story Talker is a free, open-source GUI frontend to the Festival Text-to-speech Synthesis engine. It is designed for speaking long plain text or HTML files, such as e-books and web articles. It is not intended as a general-purpose screen reader and does not target the blind. Story Talker enhances Festival by offering pause and resume of spoken text. It will automatically bookmark the last sentence spoken so that you may later restart speaking from the bookmark. Story Talker was developed for Linux, but may run under any platform that can run Python, wxPython, and Festival (not tested). You can learn more about Story Talker at http://storytalker.sourceforge.net/

ANN: Pyblosxom 0.8.1
by Wari Wahab Oct. 3, 2003

Oct. 3, 2003

Pyblosxom 0.8.1 --------------- Pyblosxom is a weblog engine that uses standard text files located on your filesystem as a database of weblog entries. The concept is simple, managing content is as easy as editing a text file with your favourite text editor. Announcement ------------ After a long testing phase, pyblosxom 0.8.1 is out now and you can find the files at [https://sourceforge.net/project/showfiles.php?group_id=67445&release_id=188… sourceforge]. Those who have downloaded 0.8 previously (this was not announced here) and those who used the pyblosxom comments plugin are advised to use this version, due to a flaw that was recently discovered. The CVS commit changelog can be found at http://roughingit.subtlehints.net/code/ChangeLog.html Important Changes to note in this version are: * New callback added `cb_story_end()` to fix a potential scripting attack via comments -- if the commentor enters text using $ they can access entry and config variables. * `contrib/plugins/pycategories.py`: Fixes the bug where a directory (which has no entries) has a subdirectory which does have entries doesn't get shown. * pyarchives plugin now uses templates instead of hardcoded to use `<br>`'s * Removed the configuration override feature in pyblosxom, people using this feature in their blogs should use the config plugin located [http://roughingit.subtlehints.net/pyblosxom/registry/general/flavconfig.reg… here] (Thanks to Robert Wall for this nice contribution) * Minor XHTML compliant output fixes * Changed the way we handle variable arguments. We now handle anything that is a valid python argument list (arguments, keyword arguments, no arguments, ...). * `contrib/plugins/pycalendar.py`: Re-fixed the issue where thismonth is outside of the range of keys that we have * Some code cleanups with pychecker
