[ANN] argparse 0.2 - Command-line parsing library
by Steven Bethard 24 Oct '06

24 Oct '06

Announcing argparse 0.2 ----------------------- argparse home: http://argparse.python-hosting.com/ argparse single module download: http://argparse.python-hosting.com/file/trunk/argparse.py?format=raw argparse bundled downloads at PyPI: http://www.python.org/pypi/argparse/ About this release ================== This release fixes a few minor bugs, modifies the 'store_true' and 'store_false' actions to have more natural defaults, and adds an epilog= keyword argument to ArgumentParser for text to be printed after the help messages. (The latter is in line with the `updates to optparse`_ for Python 2.5.) .. _updates to optparse: http://www.python.org/doc/2.5/whatsnew/modules.html New in this release =================== * The 'store_true' action's default is now False (instead of None). * The 'store_false' action's default is now True (instead of None). * ArgumentParser objects now accept an epilog= keyword argument. About argparse ============== The argparse module is an optparse-inspired command line parser that improves on optparse by: * handling both optional and positional arguments * supporting parsers that dispatch to sub-parsers * producing more informative usage messages * supporting actions that consume any number of command-line args * allowing types and actions to be specified with simple callables instead of hacking class attributes like STORE_ACTIONS or CHECK_METHODS as well as including a number of other more minor improvements on the optparse API. To whet your appetite, here's a simple program that sums its command-line arguments and writes them to a file:: parser = argparse.ArgumentParser() parser.add_argument('integers', type=int, nargs='+') parser.add_argument('--log', type='outfile', default=sys.stdout) args = parser.parse_args() args.log.write('%s\n' % sum(args.integers)) args.log.close()

ANN: wxPython 2.7.1.2 release
by Robin Dunn 23 Oct '06

23 Oct '06

Announcing ---------- The 2.7.1.2 release of wxPython is now available for download at http://wxpython.org/download.php. This release is a quick-turnaround bugfix release designed to solve some problems found in the 2.7.1.1 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 2.7.1.2 ------------------ Fixed a bug in the MaskedEdit controls caused by conflicting IsEmpty methods. Patch #1579280: Some mimetype optimizations on unix-like systems. wxMac: Several wx.webkit.WebKitCtrl enhancements/fixes, including: - new methods for increasing/decreasing text size, getting selection, getting/setting scroll position, printing, enabling editing, and running JavaScripts on the page. - added new event (wx.webkit.WebKitBeforeLoadEvent) for catching, and possibly vetoing, load events before they occur. - wx.webkit.WebKitCtrl now fires mouse events for certain events that it was eating before. This improves wxSplitterWindow resizing behavior. - refactoring of the sizing logic to move the Cocoa view. Tested with splitter windows, panels, notebooks and all position correctly with this. Some improvements to the drawing code in CustomTreeCtrl. Fixed refcount leak in wx.Window.GetChildren. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

ANN: Paste 1.0
by Ian Bicking 23 Oct '06

23 Oct '06

I am happy to announce the release of Paste 1.0. This release includes all the major components: Paste (core), Paste Script, Paste Deploy, and Paste WebKit. Paste actually passed the 0.x stage a long time ago. But now it's official: Paste is really stable. How stable? A lot stable. What Is Paste? -------------- URL: http://pythonpaste.org Install: easy_install Paste PasteScript PasteDeploy Paste (core) is a set of WSGI components, each of which can be used in isolation. But used together they form an unstoppable force. Team WSGI, unite! These components let you do things like create applications that proxy to other websites, mount multiple applications under different prefixes, catch exceptions and interactively inspect the environment, and much more. Paste Deploy is a configuration system for these components. Paste Script is a jack of all trades that builds new project file layouts, runs WSGI server stacks, and does application deployment. Acknowledgements ---------------- Thanks to all the people that have helped Paste get this far: Ben Bangert, Clark Evans, James Gardner, Philip Jenvy, and to Imaginary Landscape for their support during my time there, and to The Open Planning Project for their ongoing support. -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org

[ANN] Movable IDLE 0.1.0
by Fuzzyman 23 Oct '06

23 Oct '06

There is now an experimental version of **Movable IDLE** available, this is an off-shoot of the `Movable Python <http://www.voidspace.org.uk/python/movpy/>`_ project. **Movable IDLE**, version 0.1.0 can be downloaded (free) from : `Movable IDLE Download <http://www.tradebit.com/usr/voidspace/files.php/7007>`_ (Same place as the trial version of Movable Python.) **Movable IDLE** is a portable distribution of IDLE, the Python IDE, for Windows. The homepage of Movable IDLE is : http://voidspace.org.uk/python/movpy/movableidle.html This can be run without installing, and at only fifteen megabytes uncompressed it can be run from a USB stick or memory card. It comes with the full Python standard library, and should be capable of running almost any program that can be run with IDLE. Hopefully this will be useful for educational and experimental purposes. Limitations ======== **Movable IDLE** does not have all the clever trickery that **Movable Python** does. This means that the `win32 <http://sourceforge.net/projects/pywin32>`_ extensions, or any program that uses ``imp.find_module`` are unlikely to work. It also won't work with programs that have another event loop, like other GUI toolkits. If you need these features, try `Movable Python`_. On the other hand, if you do find bugs or restrictions, post them to the `Movable Python Mailing List <http://groups.google.com/group/movpy>`_ and it may be possible to fix them. This is the right place to post feedback and suggestions as well. License ====== **Movable IDLE** is copyright *Michael Foord*, 2006. It is free, but not Open Source. You are free to copy and distribute **Movable IDLE**, but not to charge for it. It may not be included in any distribution which charges directly or indirectly, without express permission. The following sections of the `Movable Python License <http://www.voidspace.org.uk/python/movpy/license.html>`_ also apply : * *Disclaimer* * *Limitations* * *Restricted Uses*

csounds routines beta 7 is out
by edexter 22 Oct '06

22 Oct '06

csounds routines beta 7 is out. I would like to mention this might be a good project for people just starting out because all you are doing is messing with text files to set things up to do amazing things and without the dreaded re module (so far). https://sourceforge.net/project/showfiles.php?group_id=156455&package_id=20… Dex Tracker will not be updated until I save the .sco editor saving files working routines get_instr(from_file, to_file, instr_num) from_file is the .csd file that you are reading to to file is where you wish the shortened orc file saved. Currently the plan is to save then as svc files. instr_num is the instrument number that is to be ripped. The purpose is part of an overall system but it can be used to rip orc files from other csd files. There will be parts of instruments that are not captured in some or maybe alot of .csd files. If there is donated code to adress that it will be given a different name most likely. csdInstrumentList(From_file) from_file is the file that is to be read from. This will return two lists instr_number that is a list of numbers currently in the csd file and comments wich is any comment that is included on the instr line following the instr number full_orc_file(from_file, to_file) from_file is the shortened orc file to be read from. To file is the full orc file to be written to. The routine reads a shortened orc format and writes a header part to create a full orc file. get_score(from_file, to_file, instr_num) from_file the file to get the score from. to_file is the file it is to be saved to. instr_num the instrument number that is to be ripped from the csd file. Del_Instr(from_file, instr) for instr will pick up i1 and i10 in test splitline is probily helpfull csoundgrid(filename, header_string) Loads a file (We want it for .orc files but the editor doesn't care what it is) and places the lines into a grid. The header string is a string that is defined by the user that for the purposes of editing .sco files should be placed at the end of the list of words to be used as a header for the collums. sco_editor(self): This brings up a .sco file picker and passes the file picked to csoundgrid return_pins(from_file): This gives a list of all the pins that are defined with zar and zawm. It will return instr number, intrument input and instrument output http://www.dexrow.com

PSF Infrastructure has chosen Roundup as the issue tracker for Python development
by Brett Cannon 20 Oct '06

20 Oct '06

At the beginning of the month the PSF Infrastructure committee announced that we had reached the decision that JIRA was our recommendation for the next issue tracker for Python development. Realizing, though, that it was a tough call between JIRA and Roundup we said that we would be willing to switch our recommendation to Roundup if enough volunteers stepped forward to help administer the tracker, thus negating Atlassian's offer of free managed hosting. Well, the community stepped up to the challenge and we got plenty of volunteers! In fact, the call for volunteers has led to an offer for professional hosting for Roundup from Upfront Systems. The committee is currently evaluating that offer and will hopefully have a decision made soon. Once a decision has been made we will contact the volunteers as to whom we have selected to help administer the installation (regardless of who hosts the tracker). The administrators and python-dev can then begin working towards deciding what we want from the tracker and its configuration. Once again, thanks to the volunteers for stepping forward to make this happen! -Brett Cannon PSF Infrastructure committee chairman
