pyCairo
by Jim 18 Mar '07

18 Mar '07

I'd like to experiment with pyCairo, but I'm having installation problems. I've downloaded cairo-1.4.0, libpng1.2.8, zlib 1.2.3, and pycairo 1.4.0, and I've placed the DLLs for cairo, libpng, and zlib in c:\python25\dlls\. However, when I try to run "setup.py install" for pycairo I get an error message saying the installation program can't find cairo 1.4.0. I'm running Python 2.5 on WinXP. Any help will be greatly appreciated.

First version of qooxdoo json-rpc module has been released
by Ferenczi Viktor 18 Mar '07

18 Mar '07

First release of JSON-RPC module for qooxdoo has been released. qxjsonrpc is a new JSON-RPC backend for the qooxdoo JavaScript UI framework ( http://www.qooxdoo.org ). This module can be used to build server side backends in python with very little effort. Features: - HTTP transport (GET and POST, including ScriptTransport) - Build-in qooxdoo test server implementation for RPC_* tests - Very fast JSON serialization through python-cjson-1.0.3x Download and more information: http://cx.hu/qxjsonrpc/ Simply running the module provides a qooxdoo test backend at: 127.0.0.1:8000 Example: import qxjsonrpc class MyService(object): def getPi(self, *args): print 'Called: getPi%r'%(args,) return 3.14159265365 server=qxjsonrpc.HTTPServer() server.setService('myservice', MyService()) server.serve_forever() NOTE: qxjsonrpc uses an enhanced version of the very fast python-cjson 1.0.3 JSON library called python-cjson-1.0.3x. You must install python-cjson-1.0.3x before using qxjsonrpc. You can download it from: http://cx.hu/python-cjson NOTE: I haven't tested this backend with real qooxdoo components, so it may not work properly in such situations. Please drop me a mail about your success or failure. Thanx. You can send bug reports to: python(a)cx.hu (This is only a temporary solution for bug reporting, of course.)

[ANN] GCC 4.1.2 installer for Python distutils compilation
by Giovanni Bajo 18 Mar '07

18 Mar '07

Hello, This page: http://www.develer.com/oss/GccWinBinaries contains a friendly Windows installer for GCC 4.1.2 (MinGW binary version), with full support for integrating it with Python installations so that it is used by distutils to compile Python extensions. Direct download link: http://www.develer.com/~rasky/gcc-4.1.2-mingw-setup.exe Who needs this package? * People who wants to use FLOSS tools to develop Python extensions. * People who wants to use the recent GCC 4.1.2 to develop Python extensions, given that it easily outperforms the 4-years-old Visual Studio .NET 2003. What's special about this? * mingw.org still has GCC 3.4.2, so go figure. Also, you need to compose other packages together. This is a single installer with everything inside. * By default, MinGW GCC links with MSVCRT.DLL, and not MSVCR71.DLL (used by Python 2.4 and 2.5). Fixing this is pretty complicate, and there's much confusion (Google turns up red herrings). This package handles everything for you, and it just works. -- Giovanni Bajo Develer S.r.l. http://www.develer.com

Enhanced python-cjson 1.0.3 version: 1.0.3x
by Ferenczi Viktor 18 Mar '07

18 Mar '07

Enhanced version of python-cjson 1.0.3 has been released. It's numbered 1.0.3x, where x stands for eXtension. The main improvement is the ability to extend the JSON encoder and decoder with extensions functions to serialize/unserialize objects not in the original JSON specification. This is achieved without sacrificing the speed and stability of the original implementation. Please send bug reports to python(a)cx.hu and do not contact the original author (Dan Pascu) about this version. Download and more information: http://cx.hu/python-cjson/ Example to encode/decode python date and datetime objects as JavaScript Date objects: import re import cjson import datetime # Encoding Date objects: def dateEncoder(d): assert isinstance(d, datetime.date) return 'new Date(Date.UTC(%d,%d,%d))'%(d.year, d.month, d.day) json=cjson.encode([1,datetime.date(2007,1,2),2], extension=dateEncoder) assert json=='[1, new Date(Date.UTC(2007,1,2)), 2]' # Decoding Date objects: re_date=re.compile('^new\sDate\(Date\.UTC\(.*?\)\)') def dateDecoder(json,idx): json=json[idx:] m=re_date.match(json) if not m: raise 'cannot parse JSON string as Date object: %s'%json[idx:] args=cjson.decode('[%s]'%json[18:m.end()-2]) dt=datetime.date(*args) return (dt,m.end()) # must return (object, character_count) tuple data=cjson.decode('[1, new Date(Date.UTC(2007,1,2)), 2]', extension=dateDecoder) assert data==[1,datetime.date(2007,1,2),2]

Front Range Pythoneers Monthly Meeting: Wed, Mar 21, in Boulder, Colorad
by frpythoneers＠gmail.com 17 Mar '07

17 Mar '07

== Meeting: Wednesday, March 21, 2007 == * Time: 6-8 PM * Location: bivio Software, Inc., 28th and Iris, Boulder, CO. Above Hair Elite in Suite S. There is abundant parking. This Wednesday (March 21) we have a great lineup of PyCon 2007 talks from local presenters: * Matt Boersma will present "Write Less Code with XRC for wxPython": an easier way to do GUI layout using wxWidget's XML-based resource system. * Sean Reifschneider will present "Python and vim: Two great tastes that go great together". The vim editor includes extensive abilities for customization and scripting. In addition to its own simple macro language, vim also supports calling Python code. This Python code has access back into vim for manipulating the edit buffer as well as running normal vim commands. Examples demonstrated in this talk will include automatically detecting indentation style (tabs/N spaces), automatic update of DNS "serial" numbers when editing DNS zone files, mail alias tab-expansion, and a time tracking application using a "domain specific vim" as the user interface. Other items to talk about: * BoulderSprint. The next sprint will be April 28 on the IPython1 Beta. This would be an excellent opportunity to learn about decorators, Twisted, and other advanced Python concepts while helping getting this amazing shell to beta status. * Google Summer of Code. The Python Software Foundation's application to join GSoC was just approved. It's not too late to be a mentor. But the student application deadline is March 24! We will have food & drink available as usual. Hope to see you there! More info: http://wiki.python.org/moin/FrontRangePythoneers

Regular Toronto Python User's Group (PyGTA) meeting next Tuesday
by Mike C. Fletcher 13 Mar '07

13 Mar '07

We will be having our regular monthly PyGTA meeting on the 20th of March, 2007. Our planned topic is an introduction to the One Laptop Per Child project, and particularly the Python-coded Sugar development environment. We'll probably also have some discussion on news and events in the Python world, such as the University of Toronto choosing Python as its first-year teaching language. As usual we will be meeting in the cool and funky Linux Caffe. It's located at the corner of Grace and Harbord streets in downtown Toronto. We start gathering around 6:30pm and get started with the more formal discussions around 7:00pm. We normally wrap up the formal session between 8:30 and 9:00 and head out for beer, ice-cream and the like. http://web.engcorp.com/pygta/wiki/NextMeeting Have fun all, Mike -- ________________________________________________ Mike C.
