ANN: Urwid 0.9.0 - Console UI library
by Ian Ward 20 Feb '06

20 Feb '06

Announcing Urwid 0.9.0 ---------------------- Urwid home page: http://excess.org/urwid/ Tarball: http://excess.org/urwid/urwid-0.9.0.tar.gz Screenshots: http://excess.org/urwid/utf8examples.html About this release: =================== This is the first release of Urwid with UTF-8 input and display support. A new raw_display module was added to enable UTF-8 display. This module also fixes the "dead corner" in the bottom right of the screen and improves legibility of bright text in some terminals. New in this release: ==================== - New support for UTF-8 encoding including input, display and editing of narrow and wide (CJK) characters. Preliminary combining (zero-width) character support is included, but full support will require terminal behavior detection. Right-to-Left input and display are not implemented. - New raw_display module that handles console display without relying on external libraries. This module was written as a work around for the lack of UTF-8 support in the standard version of ncurses. Eliminates "dead corner" in the bottom right of the screen. Avoids use of bold text in xterm and gnome-terminal for improved text legibility. - Fixed overlay bug related to UTF-8 handling. - Fixed Edit.move_cursor_to_coords(..) bug related to wide characters in UTF-8 encoding. About Urwid =========== Urwid is a console UI library for Python. It features fluid interface resizing, UTF-8 support, multiple text layouts, simple attribute markup, powerful scrolling list boxes and flexible interface design. Urwid is released under the GNU LGPL.

Yet another template engine : HYPY
by manatlan 20 Feb '06

20 Feb '06

HyPy : means HYperText in PYthon It's yet another template engine, under GPL2 license The main feature is that it let you code yours templates like you code your python. (the indentation defines the structure of the html). So, it's very easy to render xhtml content. But hypy let you render any kind of string document too ! It's a very young project, but i think it's usable. Features : - let you code your html like you code in python - lightweight engine (300 lines) - Compile templates to bytecode (pyc files) - classical clauses (if/else, for, capture ...) - templates inheritances (concept of masterpages and childpages) Url (tutorial and download) : http://manatlan.online.fr/hypy.php

[ANN] ConfigObj 4.2.0
by Fuzzyman 19 Feb '06

19 Feb '06

`ConfigObj 4.2.0 <http://www.voidspace.org.uk/python/configobj.html>`_ is now available. The main improvements are *full* Unicode support,a s well as the addition of the 'convenience' `Section Methods <http://www.voidspace.org.uk/python/configobj.html#section-methods>`_ * *as_bool* * *as_int* * *as_float* More compelling reasons to choose **ConfigObj** for reading and writing config files in Python. What's New ? ========== The full changelog is : Removed ``BOM_UTF8`` from ``__all__``. The ``BOM`` attribute has become a boolean. (Defaults to ``False``.) It is *only* ``True`` for the ``UTF16`` encoding. File like objects no longer need a ``seek`` attribute. Full unicode support added. New options/attributes ``encoding``, ``default_encoding``. ConfigObj no longer keeps a reference to file like objects. Instead the ``write`` method takes a file like object as an optional argument. (Which will be used in preference of the ``filename`` attribute if that exists as well.) utf16 files decoded to unicode. If ``BOM`` is ``True``, but no encoding specified, then the utf8 BOM is written out at the start of the file. (It will normally only be ``True`` if the utf8 BOM was found when the file was read.) File paths are *not* converted to absolute paths, relative paths will remain relative as the ``filename`` attribute. Fixed bug where ``final_comment`` wasn't returned if ``write`` is returning a list of lines. Deprecated ``istrue``, replaced it with ``as_bool``. Added ``as_int`` and ``as_float``. What is ConfigObj ? =============== **ConfigObj** is a simple but powerful config file reader and writer: an *ini file round tripper*. It's main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though. It is intended as a more powerful (but simpler to use) replacement for `ConfigParser <http://docs.python.org/lib/module-ConfigParser.html>`_. It's features include : * Nested sections (subsections), to any level * List Values * Multiple Line Values * Full Unicode support * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - repeated sections - and allowing default values * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies

pywinauto 0.2.1 released - lots of new functionality
by Mark Mc Mahon 19 Feb '06

19 Feb '06

Hi, The 0.2.1 release of pywinauto is now available. pywinauto is a set of open-source (LGPL) modules for using Python as a GUI automation 'driver' for Windows NT based Operating Systems (NT/W2K/XP). SourceForge project page: http://sourceforge.net/projects/pywinauto Download from SourceForge http://sourceforge.net/project/showfiles.php?group_id=157379 Here is the list of changes: 0.2.1 Small Release number - big changes ------------------------------------------------ 17-Feb-2006 * Quick release to get many changes out there - but this release has been less tested then I would like for a 0.3.0 release. * Allow access to non text controls using the closest Text control. This closest text control will normally be the static/label associated with the control. For example in Notepad, Format->Font dialog, the 1st combobox can be refered to as "FontComboBox" rather than "ComboBox1" * Added a new control wrapper - ``PopupMenuWrapper`` for context menu's You can now work easily with context menu's e.g. :: app.Notepad.Edit.RightClick() # need to use MenuClick rather then MenuSelect app.PopupMenu.MenuClick("Select All") app.Notepad.Edit.RightClick() app.PopupMenu.MenuClick("Copy") I could think of merging the ``RightClick()`` and ``MenuSelect()`` into one method ``ContextMenuSelect()`` if that makes sense to most people. * Added Support for Up-Down controls * Not all top level windows now have a FriendlyClassName of "Dialog". I changed this because it made it hard to get windows of a particular class. For example the main Notepad window has a class name of "Notepad". This was primarily implemented due to work I did getting the System Tray. * Renamed ``StatusBarWrapper.PartWidths()`` to ``PartRightEdges()`` as this is more correct for what it returns. * Changed HwndWrapper.Text() and SetText() to WindowText() and SetWindowText() respectively to try and make it clearer that it is the text returned by GetWindowText and not the text that is visible on the control. This change also suggested that EditWrapper.SetText() be changed to SetEditText() (though this is not a hard requirement EditWrapper.SetText() still exists - but may be deprecated. * Added ClickInput, DoubleClickInput, RightClickInput, PressMouseInput ReleaseMouseInput to HwndWrapper - these use SendInput rather then WM_LBUTTONDOWN, WM_RBUTTONUP, etc used by Click, DoubleClick etc. I also added a MenuClick method that allows you to click on menu items. This means you can now 'physically' drop menus down. * Some further working with tooltips that need to be cleaned up. * Fixed a bug where coordinates passed to any of the Click operations had the X and Y coordinates swapped. * Added new MenuItem and Menu classes that are to the most part hidden but you can get a menu item by doing :: app.Notepad.MenuItem("View") app.Notepad.MenuItem("View->Status Bar") MenuItems have various actions so for example you can use ``MenuItem.IsChecked()`` to check if the menu item is checked. Among other methods there are ``Click()`` and ``Enabled()``. * Modified the 'best match' algorithm for finding controls. It now searches a couple of times, and tries to find the best fit for the text passed to it. The idea here is to make it more "Select what I want - not that other thing that looks a bit like what I want!". It is possible this change could mean you need to use new identifiers in scripts - but in general very little modification should be necessary. There was also a change to the algorithm that looked for the closest text control. It missed some obvious controls in the previous implementation. It also had a bug for controls above the control rather than to the left. * Added a new example scripts SaveFromInternetExplorer.py and SaveFromFirefox.py which show automating downloading of a page from either of these browsers. * Added yet more unit tests, there are now a total of 134 tests. If you want to follow this project then please sign up to the mailing list: https://lists.sourceforge.net/mailman/listinfo/pywinauto-users Thanks Mark -------------------------------------------- Mark Mc Mahon Manchester, NH 03110, USA <P><A HREF="http://sourceforge.net/projects/pywinauto">pywinauto 0.2.1</A> Simple Windows GUI automation with Python.

ANN: PyQwt3D-0.1.1 released
by Gerard Vermeulen 18 Feb '06

18 Feb '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, MacOS/X and Windows platforms (practically any platform supported by Qt and Python). Changes: - support for NumPy, see http://numeric.scipy.org - support for SIP-4.3.x - build fixes for MacOS/X The home page of PyQwt3D is http://pyqwt.sourceforge.net. PyQwt3D-0.1.1 requires: 1. Python-2.4.x or -2.3. 2. PyQt-3.15.x or -3.14.x. 3. SIP-4.3.x or -4.2.1. 4. Qt-3.3.x, -3.2.x, or -3.1.x. 5. QwtPlot3D-0.2.6. Have fun -- Gerard Vermeulen
