ANN: GMPY 1.11rc1 is available
by casevh 30 Nov '09

30 Nov '09

Everyone, I'm pleased to annouce that a new version of GMPY is available. GMPY is a wrapper for the MPIR or GMP multiple-precision arithmetic library. GMPY 1.11rc1 is available for download from: http://code.google.com/p/gmpy/ In addition to support for Python 3.x, there are several new features in this release: - Even faster conversion to/from Python longs. - Performance improvements by reducing function overhead. - Performance improvements by improved caching. - Support for cdivmod, fdivmod, and tdivmod. - Unicode strings are accepted on Python 2.x and 3.x. - Fixed regression in GMPY 1.10 where True/False were no longer recognized. Comments on provided binaries The 32-bit Windows installers were compiled with MinGW32 using MPIR 1.3.0rc3 and will automatically recognize the CPU type and use code optimized for the CPU at runtime. The 64-bit Windows installers were compiled Microsoft's SDK compilers using MPRI 1.3.0rc3. Detailed instructions are included if you want to compile your own binary. Future plans On releasing the GIL: I have compared releasing the GIL versus the multiprocessing module and the multiprocessing module offers better and more predictable performance for embarrassingly parallel tasks than releasing the GIL. If there are requests, I can add a compile- time option to enable threading support but it is unlikely to become the default. On mutable integers: The performance advantages of mutable integers appears to be 20% to 30% for some operations. I plan to add a new mutable integer type in the next release of GMPY. If you want to experiment with mutable integers now, GMPY can be compiled with mutable version of the standard 'mpz' type. Please see the file "mutable_mpz.txt" for more information. Please report any issues! casevh

ciss-0.1: code-centered ISSUES.txt issue tracking
by holger krekel 28 Nov '09

28 Nov '09

Hi all, just released ciss-0.1, my attempt at (what i call) code-centered issue tracking. ciss is: - a command line tool for managing your ISSUES.txt - code-centered: associate issues to files in your project - extensible: assign tags for status/milestone/custom usage. - ueber-powerful issue editing: your text editor! - well tested (more tests than code) If that appeals to you check it out: http://codespeak.net/ciss And in case you wonder, why i don't use pitz or ditz? For one, I don't want to edit my issues from an interactive Python prompt, sorry. Second, they create directories and pickle-files and whatnot - i just want to keep a plain text file for a number of projects and using a text editor and a nice cmdline tool is the fastest way i can imagine. Oh, and I do see use in web-based issue interaction but keeping issues close-to-code (tm) and easy-to-edit (tm) is just so much more fun. Besides, i believe 'ciss' could learn to round-trip with existing trackers. anyway, have fun, holger

cmndbot 0.1 beta 1 released
by Bart Thate 28 Nov '09

28 Nov '09

So once again i bite the bullet because i can no longer wait on going public with this. I'm pleased to announce CMNDBOT 0.1 BETA1 to the world as this is the first released of my port of GOZERBOT to the Google Application Engine, enabling it on wave, web and xmpp. I'll paste here the README to explain what it does: CMNDBOT is a port of gozerbot to google wave platform. GOZERBOT needed to be completely rewritten as programs running on google application engine (GAE) run within a CGI model which means that the bot get loaded on every request (unless its cached). Core functionality is available right now but most plugins need to be ported still. Besides wave the bot also supports web and jabber (XMPP) access. this is the code that is being run by the cmndbot.appspot.com bot and is free code (BSD license). you can clone it to run your own cmndbot or just to read how things are being done. no fear in reading cmndbot code ! as the name says cmndbot allows you to execute commands that you can program easily through the use of plugins. example: from gozerlib.commands import cmnds def handle_hello(bot, event): event.reply("hello %s" % event.userhost) cmnds.add('hello', handle_hello, 'USER') as of now a few gozerbot plugins are being ported to cmndbot, namely: * eight ball * ipcalc * todo * wikipedia * infoitem * gcalc * RSS other plugins will follow but the focus is now mainly on the bots core. CMNDBOT is accessible at http://cmndbot.appspot.com (WEB) or cmndbot(a)appspot.com (WAVE/XMPP). A gadget is also in the works at http://cmndbot.appspot.com/cmnd.xml but it only works with google chrome for now .. my javascript skills are very *kuch* young ;] actualy this code is still young as docs are mostely missing and the bot really needs to be tested, but thats what this release is for, rememer this is still version 0.1 ! code is at http://cmndbot.googlecode.com/hg I hope people are interested in developing this bot with me, if you do you can contact me at bthate(a)gmail.com or bthate(a)googlewave.com Bart

pywinauto 0.3.9 released - (experimental new Sendkeys) and various fixes
by Mark Mc Mahon 27 Nov '09

27 Nov '09

Hi, The 0.3.9 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 https://sourceforge.net/projects/pywinauto/files/pywinauto/0.3.9/pywinauto-… Here is the list of changes from 0.3.8: * Major change this release is that Sendkeys is no longer a requirement! A replacement that supports Unicode is included with pywinauto. (hopefully soon to be released as a standalone module). Please note - this is still quite untested so this release should be treated with some care.. * Made sure that default for WindowSpecification.Window_() was to look for non top level windows. The defaults in find_windows() had been changed previously and it now needed to be explicitly overridden. * Fixed a missing reference to 'win32defines' when referencing WAIT_TIMEOUT another typo of false (changed to False) * Removed the restriction to only get the active windows for the process, now it will be possible to get the active windows, even if a process is not specified. From http://msdn.microsoft.com/en-us/library/ms633506%28VS.85%29.aspx it gets the active window for the foreground thread. * Hopefully improved Delphi TreeView and ListView handling (added window class names as supported window classes to the appropriate classes). * Added support for running UI tests with reference controls. (requried for some localization tests) * Various PyLint and PEP8 fixes made. 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 <P><A HREF="http://sourceforge.net/projects/pywinauto">pywinauto 0.3.9</A> Simple Windows GUI automation with Python.

ANN: pdfrw pure-Python PDF file reading and writing
by Patrick Maupin 27 Nov '09

27 Nov '09

pdfrw is a basic PDF file manipulation library, developed and tested on Python 2.5 and 2.6. pdfrw can read and write PDF files, and can also be used to read in PDFs which can then be used inside reportlab (as source material for new PDFs). This is also the underlying library for a new rst2pdf extension (not yet released, but in rst2pdf subversion) which allows arbitrary fragments of source PDFs to be embedded in the output PDF (without rasterization). No releases yet (and none immediately planned), but the interface is reasonably stable, it seems to work pretty well, and you can download the code and a few working examples at pdfrw.googlecode.com Feedback and/or code contributors always welcome! Best regards, Patrick Maupin
