29 Oct '06

Leo 4.4.2.1 final is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 Leo 4.4.2.1 final fixes a recent bug that caused Leo not to create the .leoRecentFiles.txt file properly in some situations. There are no known significant bugs in this version of Leo. Leo 4.4.2 final fixes a few bugs and adds support for pymacs. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4.2: ---------------------------- - You can now store settings in myLeoSettings.leo without fear of those settings being changed by cvs updates or in future versions of Leo. - Leo's vnode and tnode classes are now completely independent of the rest of Leo. Some api's have been changed. This 'big reorg' and may affect scripts and plugins. - Leo's vnode and tnode classes can optionally be compatible with ZODB databases, i.e., they can optionally derive from ZODB.Persistence.Persistent. See Chapter 17: Using ZODB with Leo for details. - The leoOPML plugin defines commands to read and write OPML files. - The slideshow plugin allows Leo to run slideshows defined by @slideshow and @slide nodes. - The leo_to_rtf and leo_to_html plugins create rtf and html files from Leo outlines. - Much faster navigation through the outline. - When focus is in the outline pane, you can move to headlines by typing the first letter of headlines. - The find command now optionally closes nodes not needed to show the node containing the present match. - Numerous changes that make Leo easier to use without using a mouse, including new commands and options. - Many new minibuffer commands now appear in the Cmds menu. - A sax parser can now optionally read .leo files.

ANN: PyQwt3D-0.1.2
by Gerard Vermeulen 29 Oct '06

29 Oct '06

What is PyQwt3D? - it is a set of Python bindings for the QwtPlot3D C++ class library which extends the Qt framework with widgets for 3D data visualization. PyQwt3D inherits the snappy feel from QwtPlot3D. The examples at http://pyqwt.sourceforge.net/pyqwt3d-examples.html show how easy it is to make a 3D plot and how to save a 3D plot to an image or an (E)PS/PDF file. - it requires and extends PyQt, a set of Python bindings for Qt. - it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (any combination of NumPy, numarray, and numarray) and optionally SciPy in a GUI Python application or in an interactive Python session. - it runs on POSIX, Mac OS X and Windows platforms (practically any platform supported by Qt and Python). New features: - support for Python-2.5 (requires PyQt and SIP snapshots or the future PyQt-3.17, PyQt-4.1 and SIP-4.5) - support for Qt-4.2.x and -4.1.x - support for NumPy-1.0, see http://numpy.scipy.org - PyQwt3D.OpenGL gives access to a small subset of the OpenGL API - EnrichmentDemo.py example demonstrates PyQwt3D.OpenGL The home page of PyQwt3D is http://pyqwt.sourceforge.net. PyQwt3D-0.1.2 requires: 1. Python-2.5.x,-2.4.x, or -2.3. 2. PyQt-4.0.x, or -3.16.x (or the future PyQt-4.1 or PyQt-3.17) 3. SIP-4.4.x (or the future SIP-4.5) 4. Qt-4.2.x, Qt-4.1.x, Qt-3.3.x, or -3.2.x. 5. QwtPlot3D-0.2.6. Have fun -- Gerard Vermeulen

ANN: wxPython 2.7.1.3
by Robin Dunn 26 Oct '06

26 Oct '06

Announcing ---------- The 2.7.1.3 release of wxPython is now available for download at http://wxpython.org/download.php. This release is a yet another quick-turnaround bugfix release designed to solve some problems, plust some minor enhancements. This will likely be the last 2.7.1.x release. Source and binaries are available for both Python 2.4 and 2.5 for Windows and Mac, as well some pacakges for varous Linux distributions. A summary of changes is listed below and also at http://wxpython.org/recentchanges.php. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.3+, in most cases the native widgets are used on each platform. Changes in 2.7.1.3 ------------------ wxGTK: The wx.ALWAYS_SHOW_SB style is now supported. Fixed name errors in the old wxPython package namespace. As a reminder, use of this package is deprecated and you are encouraged to switch your programs over to the wx package. Fixed wx.glcanvas.GLCanvas.SetCurrent to be compatible with prevoius versons. Added wx.StandardPaths.GetTmpDir. Bug fixes in the wx.ListCtrl on Mac from Kevin Olivier, allowing it to send events properly again. There is also a new native implementation of wx.ListCtrl available, which will be used for wx.LC_REPORT style list controls if you set the "mac.listctrl.always_use_generic" SystemOption to zero. In a future release this will be the default. Added a sample to the demo that shows some of what can be done with the new wx.GraphicsContext and wx.GraphicsPath classes. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

[ANN]UliPad 3.5 released
by limodou 23 Oct '06

23 Oct '06

What's it? ======== It's an Editor based on wxPython. NewEdit is the old name, and UliPad is the new name. UliPad uses Mixin and Plugin technique as its architecture. Most of its classes can be extended via mixin and plugin components, and finally become an integrity class at creating the instance. So UliPad is very dynamic. You can write the new features in new files, and hardly need to modify the existing code. And if you want to extend the existing classes, you could write mixins and plugins, and this will be bound to the target class that I call "Slot Class". This technique will make the changes centralized and easily managed. What's new in 3.5 ============== New features and improvement: #. Add not automatically clear content of Message window, and add Shift+F5 shortcut #. Use FlatNotebook instead of Notebook #. Add spell checking plugin, and you should install pyEnchant module #. Auto save side pane size #. Auto maximize when double-click on tab of notebook, only 50% for side pane #. Improve acp format, and you can use {#text#} represent selected text #. Add support for creating ePyDoc comment to function definition #. Add personal info management, only user name for now #. Add session management #. Add live regular expression searching, you can type regex dynamically and watch the result immediately #. Add CloseOther plugin, thanks for nmweizi, and it can keep current document but close all others documents #. Add smart navigation, and it can remember the path of files visited #. Improve Ctrl+B to jump to last modified position #. Add a checkbox for reStructuredText Html view window, and it can used for stop automatically refresh the html content as you changing the ReST file #. Auto close syntax check window as there are no errors to current python file #. Auto support for dropping files and directories to directory window #. Dynamically popup menu creation of notebook #. Add open Dos window here for current document on popup menu of notebook, only works for windows now #. Add custom FlatButtons control written by myself, used in smart navigation #. Improve support for custom toolbar control in toolbar process #. Improve project process: refactor, adding and deleting config process #. Improve Chinese support in rerange.py script Changes: #. Remove the process for input assistant in OnKeyDown of editor, in order to simplify the process #. Fix don't check the syntax for python file as saving bug #. Fix can't search for document as opening it bug #. Fix incorrect enabled status for toolbar buttons bug #. Fix incorrect syntax highlight process bug #. Refactor and fix New... menuitem is not the same with toolbar menu bug #. Fix losing input focus after saving file bug #. Fix pressing Ctrl+F4 will quit UliPad bug #. Change recent files and recent path menu to popup menu, so it will speed opening file and saving file #. Fix the redirection process of executing python program, and add an option for showing parameter window on every running #. Fix the efficient of input assistant bug #. Change Ctrl+Enter to Shift+Enter Where to download it? ================ download lastest version 3.5: http://wiki.woodpecker.org.cn/moin/UliPad?action=AttachFile&do=get&target=u… also have windows installer: http://wiki.woodpecker.org.cn/moin/UliPad?action=AttachFile&do=get&target=U… wiki: http://wiki.woodpecker.org.cn/moin/UliPad svn: http://cvs.woodpecker.org.cn/svn/woodpecker/ulipad/trunk maillist: http://groups.google.com/group/ulipad If you have any problem as using UliPad, welcome to join the UliPad maillist to discuss.

Talks at PyCon that Teach How to Be Better Programmers
by Jeff Rush 23 Oct '06

23 Oct '06

I've been looking over the mix of talk proposals we have so far for PyCon 2007. We're got 17 so far, with a good number of case histories. Now case histories are good, don't get me wrong, we want Python to be successful and it is interesting to hear how it is being used. But according to the feedback forms from last year, we need more talks that actually teach you how to be better programmers, especially if we want to bring new talent into the community. Where are the talks about how to best use select features of the language, that demonstrate how to use some of the more powerful design patterns in Python? Python 2.4 and 2.5 have added significant new capabilities to the language and we need the advance scouts to help some of us just now discovering them. Many of us do not adopt new features as soon as they appear. Often at PyCon we have looked to people like Alex Martelli to get down and dirty with aspects of the language, but unfortunately he is unable to make it in 2007. Who else is good at explaining how and when to apply language constructs? Not sure where to start? For brainstorming here are four talks I've not seen at recent PyCons and that I think would be well received. Anything about design patterns would be good too. ---- How to Optimize Your Python Programs? * optimization - speed or memory? * common mistakes o use of repeated append on strings o not using Numeric when doing array operations + such as graphics, sound o close your handles, release your objects where possible * what slows Python down? o looping? o function calls? * methods to speed things up o pre-binding o push looping into C extensions o code in C extensions releases global lock and speeds up execution on multicores * shrinking your memory footprint http://us.pycon.org/TX2007/PgmOptimizing ---- Key Python Technologies You Should Know The idea of this talk is to highlight some of the cross-domain technologies that a programmer would find useful in his toolbelt as he moves among problems or job positions. * criteria for inclusion in talk: o cross-platform o cross-domain o of general use, not obscure or a niche * docutils, reST (docstrings, READMEs, page templates, wiki markup, doctests) * interfaces/adapters * eggs * unit test frameworks * DB-API? http://us.pycon.org/TX2007/PyTechToKnown ---- Taking Your Programming Environment to a New Level What do skilled Python programmers keep around them that makes them better programmers? * pymacs, pyvim * pylint * ipython and other command shells * brief walk-thru of GUI IDEs * keeping docs at your fingertips * books to keep at your side (this talk could be run as a panel among experts) http://us.pycon.org/TX2007/PyPgmEnv ---- What the Heck Does "Pythonic Programming Style" Mean Anyway? The term is often tossed at someone on the list, but what are they talking about? How can a newbie learn the style? * common idioms you see in source code * attributes versus getters/setters * package dir layouts o import all in __init__? o fully name-qualify all imports? http://us.pycon.org/TX2007/PyPgmStyle I've included links to the wiki pages holding the outlines in hopes that people will suggest additional topics to cover. To give a talk, before Oct 31 visit the conference page at: http://us.pycon.org/TX2007/CallForProposals Jeff Rush PyCon 2007 Co-Chair

RELEASED Python 2.3.6, release candidate 1
by Anthony Baxter 23 Oct '06

23 Oct '06

On behalf of the Python development team and the Python community, I'm announcing the release of Python 2.3.6 (release candidate 1). Python 2.3.6 is a security bug-fix release. While Python 2.5 is the latest version of Python, we're making this release for people who are still running Python 2.3. Unlike the recently released 2.4.4, this release only contains a small handful of security-related bugfixes. See the website for more. * Python 2.3.6 contains a fix for PSF-2006-001, a buffer overrun * in repr() of unicode strings in wide unicode (UCS-4) builds. * See http://www.python.org/news/security/PSF-2006-001/ for more. This is a **source only** release. The Windows and Mac binaries of 2.3.5 were built with UCS-2 unicode, and are therefore not vulnerable to the problem outlined in PSF-2006-001. The PCRE fix is for a long-deprecated module (you should use the 're' module instead) and the email fix can be obtained by downloading the standalone version of the email package. Most vendors who ship Python should have already released a patched version of 2.3.5 with the above fixes, this release is for people who need or want to build their own release, but don't want to mess around with patch or svn. Assuming no major problems crop up, a final release of Python 2.3.6 will follow in about a week's time. Python 2.3.6 will complete python.org's response to PSF-2006-001. If you're still on Python 2.2 for some reason and need to work with UCS-4 unicode strings, please obtain the patch from the PSF-2006-001 security advisory page. Python 2.4.4 and Python 2.5 have both already been released and contain the fix for this security problem. For more information on Python 2.3.6, including download links for source archives, release notes, and known issues, please see: http://www.python.org/2.3.6 Highlights of this new release include: - A fix for PSF-2006-001, a bug in repr() for unicode strings on UCS-4 (wide unicode) builds. - Two other, less critical, security fixes. Enjoy this release, Anthony Anthony Baxter anthony(a)python.org Python Release Manager (on behalf of the entire python-dev team)
