[ANN] buzhug 0.9 released
by Pierre Quentel 29 Sep '07

29 Sep '07

Hello, A new version of buzhug has just been published : http://buzhug.sourceforge.net buzhug is a fast, pure-Python database engine, using a syntax that Python programmers should find very intuitive The data is stored and accessed on disk (it is not an in-memory database) ; the implementation has been designed to make all operations, and especially selection, as fast as possible with an interpreted language The database is implemented as a Python iterator, yielding objects whose attributes are the fields defined when the base is created ; therefore, requests can be expressed as list comprehensions or generator expressions, instead of SQL queries : for record in [ r for r in db if r.name == 'pierre' ]: print record.name,record.age instead of cursor.execute("SELECT * IN db WHERE name = 'pierre'") for r in cursor.fetchall(): print r[0],r[1] buzhug supports concurrency control by versioning, cleanup of unused data when many records have been deleted, easy links between bases, adding and removing fields on an existing base, etc Database speed comparisons are not easy to make. I made a limited benchmark using the same use cases as SQLite's author ; it shows that buzhug is much faster than other pure-Python modules (KirbyBase, gadfly) ; SQLite, which is implemented in C, is faster, but only less than 3 times on the average Version 0.9 is a minor update, fixing a bug (forbid adding a field with the same name as an existing field) and adding a method to close the database Download : http://sourceforge.net/project/showfiles.php?group_id=167078 Documentation : http://buzhug.sourceforge.net/ Tutorial : http://buzhug.sourceforge.net/tutorial.html Users group : http://groups.google.com/group/buzhug?lnk=li Regards, Pierre

ANN: PyQt v4.3.1 Released
by Phil Thompson 28 Sep '07

28 Sep '07

Riverbank Computing is pleased to announce the release of PyQt v4.3.1 available from http://www.riverbankcomputing.co.uk/pyqt/. This is mainly a bug fix release. A Windows installer is provided for the GPL version of PyQt which contains everything needed for PyQt development (including Qt, Qt Designer, Qwt, QScintilla and the eric IDE) except Python itself. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt (Windows, Linux and MacOS/X). Like Qt, PyQt is available under the GPL and a commercial license. See http://www.riverbankcomputing.com/Docs/PyQt4/html/classes.html for the class documentation. PyQt v4 supports Qt v4 (http://www.trolltech.com/products/qt/index.html). PyQt v3 is still available to support earlier versions of Qt. PyQt v4 is implemented as a set of 11 extension modules containing approximately 400 classes and 6,000 functions and methods. QtCore The non-GUI infrastructure including event loops, threads, i18n, Unicode, signals and slots, user and application settings. QtGui A rich collection of GUI widgets. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP, SSL). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtScript A set of classes that implements a JavaScript interpreter. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. Includes an implementation of SQLite. QtSvg A set of classes to render SVG files onto Qt widgets. QtTest A set of classes to automate unit testing of PyQt applications and GUIs. QtXML A set of classes that implement DOM and SAX parsers. QtAssistant A set of classes that enables the Qt Assistant online help browser to be integrated with an application. QAxContainer A set of classes for Windows that allows the integration of ActiveX controls and COM objects. PyQt includes the pyuic4 utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. It is also able to load Designer XML files dynamically.

ANNOUNCE: wxPython 2.8.6.0
by Robin Dunn 27 Sep '07

27 Sep '07

Announcing ---------- The 2.8.6.0 release of wxPython is now available for download at http://wxpython.org/download.php. This release is mostly about fixing a number of bugs and inconsistencies in wxWidgets and wxPython. Source code is available, as well as binaries for Python 2.3, 2.4 and 2.5, for Windows and Mac, as well some pacakges for various 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 to provide a 100% native look and feel for the application. Changes in 2.8.6.0 ------------------ This release is mostly about fixing a number of bugs and inconsistencies in wxWidgets and wxPython. In other words, there have been a whole lot more changes than what is listed here, but they are not new features or API visible changes, which is what are usually listed in this file. Some Menu APIs added to make things more consistent. Added wx.MenuBar.SetMenuLabel, wx.MenuBar.GetMenuLabel, wx.MenuBar.GetMenuLabelText, wx.Menu.GetLabelText, wx.MenuItem.SetItemLabel, wx.MenuItem.GetItemLabel, wx.MenuItem.GetItemLabelText, wx.MenuItem.GetLabelText. The Get...Label functions get the raw label with mnemonics and accelerators, and the Get...LabelText functions get the text only, without mnemonics/accelerators. Added wx.BORDER_THEME style. This style will attempt to use a theme specific style, if the current platform and environment is themeable and has a specific theme style. For example, you could use this on Windows XP on a custom control to give it a themed border style that looks like what is used by default on the native wx.TextCtrl or wx.ListBox. Since there were not any more available bits for border styles, this style replaces wx.BORDER_DOUBLE. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

itools 0.16.9 released
by "J. David Ibáñez" 27 Sep '07

27 Sep '07

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.tmx itools.cms itools.ical itools.uri itools.csv itools.odf itools.vfs itools.datatypes itools.pdf itools.web itools.gettext itools.rest itools.workflow itools.handlers itools.rss itools.xhtml itools.html itools.schemas itools.xliff itools.http itools.stl itools.xml The focus of this release has been the CMS, there is one new feature, and a lot of small user interface improvements and bug fixes. The single new feature is for the Issue Tracker. Now it is possible to search issues in the tracker by multiple values (for example to find issues of high or medium priority). We have implemented a restful technique to handle edit conflicts. When two users try to modify an object at the same time, the user that changes the object first wins, the other one will get an error message. (For now we apply this technique only to Web and Wiki pages.) There is a new menu in the left column for complex objects. For now it works with the Wiki and the Tracker objects. There are also many bug fixes and user interface improvements across the whole CMS. Apart from "itools.cms", there have been some small changes in the "itools.catalog", "itools.http", "itools.html" and "itools.ical" packages. Credits: Hervé Cauwelier Nicolas Deram J.

IMDbPY 3.2 released
by Davide Alberani 25 Sep '07

25 Sep '07

IMDbPY 3.2 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about both movies and people. With this release, some fixes to support minor changes to the new IMDb layout; moreover, the ability to perform custom SQL queries with the imdbpy2sql.py script was added. Platform-independent and written in pure Python (and few C lines), it can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

ANN: PyPE 2.8.7
by Josiah Carlson 25 Sep '07

25 Sep '07

=== What is PyPE? === PyPE (Python Programmers' Editor) was written in order to offer a lightweight but powerful editor for those who think emacs is too much and idle is too little. Syntax highlighting is included out of the box, as is multiple open documents via tabs. Beyond the basic functionality, PyPE offers an expandable source tree, filesystem browser, draggable document list, todo list, filterable function list, find and replace bars (no dialog to find or replace simple strings), recordable and programmable macros, spell checker, reconfigurable menu hotkeys, triggers, find in files, external process shells, and much more. === More Information === If you would like more information about PyPE, including screenshots, where to download the source or windows binaries, bug tracker, contact information, or a somewhat complete listing of PyPE's features, visit PyPE's home on the web: http://pype.sf.net/index.shtml If you have any questions about PyPE, please contact me, Josiah Carlson, aka the author of PyPE, at jcarlson at uci.edu (remember to include "PyPE" in the subject). PyPE 2.8.7 includes the following changes and bugfixes since release 2.8.5: #-------------------------------- PyPE 2.8.7 --------------------------------- (fixed) some bugs related to the parsers module movement. (fixed) ordering of user profile path discovery to not break when confronted with insane 'HOME' environment variable on Windows (will use USERPROFILE or HOMEDRIVE/HOMEPATH first). (fixed) unrepr mechansim can now handle negative value storage for disabled realtime options, etc. #-------------------------------- PyPE 2.8.6 --------------------------------- (fixed) a bug with "Wrap Try/Except" as per emailed bug report from Ian York. (added) ability to choose what port PyPE will listen on via --port= . (fixed) workspaces in wxPython 2.8+, patch thanks to Craig Mahaney. (added) explicit exclude dirs for find in files, patch thanks to Craig Mahaney. (added) paste and down mechanism to paste and move the cursor down, patch thanks to Craig Mahaney. (added) delete right mechanism to delete everything from the cursor to the end of the line, patch thanks to Craig Mahaney. (added) delete line mechanism to delete the current line, patch thanks to Craig Mahaney. (added) paste rectangle command for rectangular pasting, patch thanks to Craig Mahaney. (fixed) support for alternate background colors thanks to bug report from Craig Mahaney. (added) macro support to Craig Mahaney's added functionality. (added) implementation for regular expression replacements, possibly to be integrated as part of a 'replace in all open documents' in the future. (added) automatic spellcheck for text and tex documents of up to 200,000 byes in size. Will only spellcheck if the user has enabled "check syntax" in the "Realtime Options". (fixed) issue when trying to save language settings when cursor position is not to be saved. (added) support for \chapter section delimiter in *tex files. (fixed) issue that prevented the highest level source listing from being sorted in the Name and Line sorted source trees. (changed) rather than reading and executing a file for configuration loading, we now use a variant of the 'unrepr()' mechanism with support for True/False. (changed) find/replace bar now uses variant of 'unrepr()' rather than the compiler module directly. (changed) moved parsers.py to plugins and stopped using import * to get its contents.
