[ANNOUNCE] PyScheme 1.5 release
by Daniel Yoo 08 Sep '04

08 Sep '04

PyScheme is a small implementation of the Scheme programming language. The 1.5 release can be found here: http://hkn.eecs.berkeley.edu/~dyoo/python/pyscheme/ PyScheme is in pure Python, and has been written (somewhat) careful to try to avoid eating up too much of the stack, even if given unusual input. It provides some of the core features in Scheme: ### >>> import pyscheme.scheme >>> pyscheme.scheme.repl(pyscheme.scheme.AnalyzingInterpreter()) Welcome to PyScheme! Type: (QUIT) to quit. [PyScheme] >>> (define (map f l) [......1)] >>> (if (null? l) [......2)] >>> '() [......2)] >>> (cons (f (car l)) [......3)] >>> (map f (cdr l))))) ok [PyScheme] >>> (map (lambda (x) (* x x)) '(1 2 3 4 5 6 7 8 9 10)) (1 4 9 16 25 36 49 64 81 100) ### And it also includes CALL/CC. People can play around with continuations in the comfort of the Python interpreter: ### >>> from pyscheme.scheme import AnalyzingInterpreter >>> interp = AnalyzingInterpreter() >>> from pyscheme.parser import parse as p >>> interp.eval(p("(define k '())")) 'ok' >>> interp.eval(p(""" ... (+ 5 (call/cc (lambda (k1) (set! k k1) 0))) ... """)) 5 >>> interp.eval(p("(k 7)")) 12 ### I'll be giving a small presentation about PyScheme in the next Baypiggies meeting on Thursday, September 9th, and I'll put up the notes of that presentation online, as soon as I'm done writing them. *grin* I hope this helps!

cx_Freeze 3.0 beta3
by Anthony Tuininga 08 Sep '04

08 Sep '04

What is cx_Freeze? cx_Freeze is a set of utilities for freezing Python scripts into executables using many of the techniques found in Thomas Heller's py2exe, Gordon McMillan's Installer and the Freeze utility that ships with Python itself. Where do I get it? http://starship.python.net/crew/atuining http://www.computronix.com/utilities.shtml (it may be a few days before the second site is updated) What's new? 1) Explicitly include the warnings module so that at runtime warnings are suppressed as when running Python normally. 2) Improve the extension loader so that an ImportError is raised when the dynamic module is not located; otherwise an error about missing attributes is raised instead. 3) Extension loaders are only created when copying dependencies since the normal module should be loadable in the situation where a Python installation is available. 4) Added support for Python 2.4. 5) Fixed the dependency checking for wxPython to be a little more intelligent. -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.

REMINDER: BayPIGgies: September 9, 7:30pm
by Aahz 08 Sep '04

08 Sep '04

The next meeting of BayPIGgies will be Thurs September 9 at 7:30pm. It will feature a presentation about pyscheme by Danny Yoo. BayPIGgies meetings are in Stanford, California. For more information and directions, see http://www.baypiggies.net/ Before the meeting, we're returning to Jing Jing at 6pm for dinner in downtown Palo Alto. Ducky Sherwood is handling that; please send RSVPs to ducky(a)osafoundation.org by 4pm Thurs. Discussion of dinner plans is handled on the BayPIGgies mailing list. Here's a repeat of Ducky's post: Jing Jing is a Chinese restaurant in downtown Palo Alto at 443 Emerson St. It is very close to the CalTrain station, and if you can't get someone to give you a ride to the meeting afterwards, the free Stanford Marguarite shuttle runs frequently between Stanford and the CalTrain station. Jing Jing official site, with link to map at bottom: http://www.jingjingonline.com/ [1] Why Jing Jing again? Because of the very sparse attendance at Paxti's Pizza last time. Advance notice: The October 14 meeting agenda has not been set. Please send e-mail to baypiggies(a)baypiggies.net if you want to make a presentation. -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "I saw `cout' being shifted "Hello world" times to the left and stopped right there." --Steve Gonedes

ZODB 3.2.2 (final) released
by Tim Peters 08 Sep '04

08 Sep '04

I'm pleased to announce the release of ZODB 3.2.2 (final). This is the version of ZODB that will ship with Zope 2.7.1 (final). Upgrading to ZODB 3.2.2 is strongly recommended for all users, and is critical for sites running ZRS. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 As promised with the ZODB 3.2.2b1 release last week, the tests for the unsupported Berkeley-based storages are now disabled in 3.2.2. In addition, a small but critical bug in FileStorage.restore() was identified and repaired. This bug didn't affect the Zope core, but is critical for sites running ZRS. See the news file for more detail: http://zope.org/Products/ZODB3.3/NEWS Note that ZODB 3.2.2 does not support Zope X3 (Zope 3 requires ZODB 3.3 -- as will Zope 2.8).

ANN: Plone Conferene 2004, Zope 3 and content management
by Paul Everitt 07 Sep '04

07 Sep '04

Zope, a Python-based application server, is migrating to the component architecture of Zope 3. "Be more Pythonic" is a major goal of Zope 3, while also letting Python developers eat Zope one bite at a time through better modularization. The Zope 3 component architecture is a major theme at the Plone Conference in Vienna, Sep 20-22: http://plone.org/events/conferences/2 The tutorial track includes a Zope 3 tutorial from Jim Fulton, a tutorial by Martijn Faassen on the "Five" project to bring Zope 3 into Zope 2, and even a tutorial on Boa Constructor with Riaan Booysen. Also, the developers of several content management products for Zope are getting together before the conference for a sprint on "The Future of Content Management with Zope 3". Jim's conference keynote will discuss the results of this effort. This will be a major conference, with attendance expected to top the 250 mark. Registration is still open: http://plone.org/events/conferences/2/Registration Do you really want to miss a conference held in a Vienna discotheque? Sign up soon and come join the fun! --Paul

[ANN] Pythonutils Updates
by fuzzyman＠gmail.com 06 Sep '04

06 Sep '04

Pythonutils Updates Yup... another exciting update to the modules/scripts maintained at - http://www.voidspace.org.uk/atlantibots/pythonutils.html *UPDATE* approx.py Version 0.5.0 This is the python cgiproxy for browsing in a restricted internet environment. It's now very nearly useable ;-) Fixed POST requests (doh) - except for list values and file uploads. Will now use cookielib if it's available and maintains separate cookie files for separate users - with both cookielib and ClientCookie. Now proxying User-agent header. Lot's more still to work on - urls in css, file uploads and authentication are the next ones. (See the TODO list - nothing insurmountable...) *UPDATE* scraper.py Version 1.3.0 A patch by Paul Perkins that fixes a bug when handling tags without attributes. *UPDATE* proxycleaner.py Version 1.0.1 Will better clean up nntp links mangled by the perl cgiproxy ;-) (approx.py doesn't mangle these...) *UPDATE* dataenc.py Version 1.1.4 Improvements since last public release : Slight docs improvement. Speed improvement in binleave and binunleave. Added the unexpired alias and the check_pass function. Changed license text. *NEW* cookielib_example.py Version 1.0.0 An example of code for fetching URLs that will happily use ClientCookie *or* cookielib (Python 2.4) *or* neither. This code is at - http://www.voidspace.org.uk/atlantibots/recipebook.html *UPDATE* configobj.py Version 3.2.1 Bugfix... oops. *UPDATE* listquote.py Version 1.1.1 Improved docs All the best, Fuzzyman

ANN: WCK for Tkinter 1.1 alpha 1 (september 5, 2004)
by Fredrik Lundh 05 Sep '04

05 Sep '04

The Widget Construction Kit (WCK) is an extension API that allows you to implement custom widgets in pure Python. The WCK can be (and is being) used for everything from light-weight display widgets to full-blown editor frameworks. The Tkinter3000 implementation of the WCK supports all recent versions of Python and Tk/Tkinter. The 1.1 alpha release adds the ability to change widget controllers, and also adds an experimental native graphics driver for Windows. Introduction: http://www.effbot.org/zone/wck-1.htm Downloads: http://www.effbot.org/downloads#tkinter3000 Documentation: http://www.effbot.org/zone/wck.htm http://www.effbot.org/zone/wck-api.htm enjoy /F
