ANN: Announcing MV3D 0.70!
by Michael Handverger 23 Jan '12

23 Jan '12

I am pleased to announce the release version 0.70 of MV3D! This release includes a massive amount of new features and over 70 bugfixes. The main focus was on usability and involved a large amount of work on tools. In 0.70, Panda3D support was brought up to par with animation, terrain texture splatting, and skydomes. One of the things we are most excited about is the Windows development environment installer. This is an easy installer that will quickly set up any Windows system to develop MV3D. MV3D is an open source multiplayer game and virtual world framework written in Python which uses Twisted for networking. It encompasses a scalable server with dynamic load balancing, a robust set of content creation tools, and an extensible 3D client application. MV3D provides the foundation to build anything from 3D chat rooms to full MMORPGs with the goal of letting you concentrate on creating a unique virtual world instead of the infrastructure to support it. For more information on MV3D and this or future releases, please visit the website at http://www.mv3d.com . The full release notes for version 0.70 are available online at this URL: http://www.mv3d.com/trac/browser/tags/mv3d-0.70/release-notes.txt . For further inquiries, feel free to stop by our IRC channel on irc.freenode.net #MV3D. New screenshots of our demo world and the Composer tool: http://www.mv3d.com/trac/screenshots/46 http://www.mv3d.com/trac/screenshots/47 Release 0.75 will be focused on bugfixing and adding full support for Linux + Ogre and OS X + Panda. We are currently looking for help porting and testing on these platforms. Enjoy, Mike

Announcing python-libarchive.
by Ben Timby 21 Jan '12

21 Jan '12

Python-libarchive is a wrapper around the excellent libarchive library. It allows you to work with many different archive formats using a single API. http://code.google.com/p/python-libarchive/ Python-libarchive is a SWIG wrapper around the library as well as some high-level Python classes to make usage easier. There are also compatibility modules for zipfile and tarfile. These modules use libarchive to deal with the archive files, but provide an interface as similar as possible to the stdlib versions. The library is usable, but by no means complete. This library was written against libarchive 3.0.X and will not work with libarchive 2. Some instructions on installing libarchive and python-libarchive are available in the Wiki. http://code.google.com/p/python-libarchive/wiki/Building There is a Google Group for feedback. http://groups.google.com/group/python-libarchive-users Thank you!

Nagare web framework 0.4.0
by Alain Poirier 18 Jan '12

18 Jan '12

Hi all, Version 0.4.0 of the Nagare web framework is now released! About Nagare ============ Nagare is a components based framework: a Nagare application is a composition of interacting components each one with its own state and workflow kept on the server. Each component can have one or several views that are composed to generate the final web page. This enables the developers to reuse or write highly reusable components easily and quickly. Thanks to Stackless Python, Nagare is also a continuation aware web framework which enables to code a web application like a desktop application, with no need to split its control flow in a multitude of controllers and with the automatic handling of the back, fork and refresh actions from the browser. Its component model and use of the continuation come from the famous Seaside Smalltalk framework. Furthermore Nagare integrates the best tools and standard from the Python world. For example: - WSGI: binds the application to several possible publishers, - lxml: generates the DOM trees and brings to Nagare the full set of XML features (XSL, XPath, Schemas ...), - setuptools: installs, deploys and extends the Nagare framework and the Nagare applications too, - PEAK Rules: generic methods are heavily used in Nagare, to associate views to components, to define security rules, to translate Python code to Javascript ... - WebOb: for its Request and Response Objects. To read more about its features: http://www.nagare.org/trac/wiki/NagareFeatures Release info and download page: http://pypi.python.org/pypi/nagare Release info and download page of the examples: http://pypi.python.org/pypi/nagare.examples Release info and download page of the pure web IDE: http://www.nagare.org/trac/wiki/NagareIde http://pypi.python.org/pypi/nagare.ide Source and documentation available at the website: http://www.nagare.org Mailing lists - the place to ask questions: http://groups.google.com/group/nagare-users Examples ======== A complete "guess a number" game to taste how easy web coding becomes using continuations: import random from nagare import component, util class Number(component.Task): """A little game to guess a number """ def go(self, comp): """The game algorithm, using continuation for a pure linear Python code In: - ``comp`` -- this component """ self.attempt = 1 number = random.randint(1, 20) comp.call(util.Confirm('I choose a number between 1 and 20. Try to guess it')) while True: x = comp.call(util.Ask('Try #%d: ' % self.attempt)) if not x.isdigit(): continue x = int(x) if x > number: comp.call(util.Confirm('Choose a lower number')) if x < number: comp.call(util.Confirm('Choose a greater number')) if x == number: comp.call(util.Confirm('You guessed the number in %d attempts' % self.attempt)) break self.attempt += 1 A simple todo list, illustrating the programmatic HTML generation, the association of view(s) to Python objects and the direct association of callbacks to HTML form elements and links: from nagare import presentation from nagare.namespaces import xhtml # A plain Python ``TodoList`` class class TodoList(object): def __init__(self): self.todo = [] def add_todo(self, msg): self.todo.append(msg) # The default HTML view, generated in programmatic HTML @presentation.render_for(TodoList) def render(self, h, comp, model): # ``h`` is a (X)HTML renderer (http://www.nagare.org/trac/wiki/RendererObjects) with h.div: for msg in self.todo: h << h.blockquote(msg) << h.hr with h.form: h << 'New todo:' << h.br h << h.textarea.action(self.add_todo) << h.br h << h.input(type='submit', value='Add') return h.root Enjoy!

by Nathan Rice 17 Jan '12

17 Jan '12

Elementwise provides helpful proxy objects which let you perform a series of computations on every element of an iterable or graph, in a lazy manner. Docs: http://packages.python.org/elementwise/ GitHub: https://github.com/nathan-rice/Elementwise Examples: The standard ElementwiseProxy: >>> nums = ElementwiseProxy([1, 2, 3, 4) >>> print nums.bit_length() 1, 2, 2, 3 >>> nums + 1 2, 3, 4, 5 >>> print nums * 2 2, 4, 6, 8 >>> print nums == 2 False, True, False, False >>> print ((nums + 1) * 2 + 3).apply(float) 7.0, 9.0, 11.0, 13.0 >>> print (nums.apply(float) + 0.0001).apply(round, 2) 1.0, 2.0, 3.0, 4.0 >>> print abs(nums - 3) 2, 1, 0, 1 >>> print (nums * 2 + 3) / 4 >>> print efoo2.undo(3) 1, 2, 3, 4 >>> print ((nums * 2 + 3) / 4).replicate([2, 2, 3, 3]) 1, 1, 2, 2 >>> words = ElementwiseProxy(["one", "two", "three", "four"]) >>> print (words + " little indians").upper().split(" ").apply(reversed).apply("_".join) * 2 'INDIANS_LITTLE_ONEINDIANS_LITTLE_ONE', 'INDIANS_LITTLE_TWOINDIANS_LITTLE_TWO', 'INDIANS_LITTLE_THREEINDIANS_LITTLE_THREE', 'INDIANS_LITTLE_FOURINDIANS_LITTLE_FOUR' The PairwiseProxy: >>> nums = PairwiseProxy([1, 2, 3, 4]) >>> nums + [1, 2, 3, 4] 2, 4, 6, 8 >>> nums * [2, 2, 3, 3] 2, 4, 9, 12 >>> nums == [2, 2, 3, 5] False, True, True, False >>> (nums.apply(float) / itertools.count(2) + itertools.count(1)).apply(round, args=itertools.repeat([2])) 1.5, 2.67, 3.75, 4.8 >>> abs(nums - [3, 2, 1, 1]) 2, 0, 2, 3 >>> (nums * [2, 2, 1, 5] + [3, 5, 9, 0]) / [4, 1, 2, 3] 1, 9, 6, 6 >>> ((nums * itertools.repeat(2) + itertools.repeat(3)) / itertools.repeat(4)).replicate([2, 2, 3, 3]) 1, 0, 0, 0 >>> ((nums * [2, 3, 4, 5]) > [5, 6, 7, 8]) != [True, True, False, True] True, True, True, False The RecursiveElementwiseProxy: >>> treenums = RecursiveElementwiseProxy([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) >>> treenums + 1 ((2, 3, 4), (5, 6, 7), (8, 9, 10)) >>> treenums * 2 ((2, 4, 6), (8, 10, 12), (14, 16, 18)) >>> (treenums * 2 + 1).apply(float) ((3.0, 5.0, 7.0), (9.0, 11.0, 13.0), (15.0, 17.0, 19.0)) Feedback is welcome.
