cx_Freeze 3.0.1
by Anthony Tuininga 03 Dec '04

03 Dec '04

What is cx_Freeze? cx_Freeze is a set of utilities for freezing Python scripts into executables using many of the techniques found in Thomas Heller's py2exe, Gordon McMillan's Installer and the Freeze utility that ships with Python itself. Where do I get it? http://starship.python.net/crew/atuining http://www.computronix.com/utilities.shtml (it may be a few days before the second site is updated) What's new? 1) Added option --default-path which is used to specify the path used when finding modules. This is particularly useful when performing cross compilations (such as for building a frozen executable for Windows CE). 2) Added option --shared-lib-name which can be used to specify the name of the shared library (DLL) implementing the Python runtime that is required for the frozen executable to work. This option is also particularly useful when cross compiling since the normal method for determining this information cannot be used. 3) Added option --zip-include which allows for additional files to be added to the zip file that contains the modules that implement the Python script. Thanks to Barray Warsaw for providing the initial patch. 4) Added support for handling read-only files properly. Thanks to Peter Grayson for pointing out the problem and providing a solution. 5) Added support for a frozen executable to be a symbolic link. Thanks to Robert Kiendl for providing the initial patch. 6) Enhanced the support for running a frozen executable that uses an existing Python installation to locate modules it requires. This is primarily of use for embedding Python where the interface is C but the ability to run from source is still desired. 7) Modified the documentation to indicate that building from source on Windows currently requires the mingw compiler (http://www.mingw.org). 8) Workaround the problem in Python 2.3 (fixed in Python 2.4) which causes a broken module to be left in sys.modules if an ImportError takes place during the execution of the code in that module. Thanks to Roger Binns for pointing this out. -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software. Real People.

MMA - Musical MIDI Accompaniment, Beta 0.12
by Bob van der Poel 03 Dec '04

03 Dec '04

I'm pleased to announce the release of my program mma - Musical MIDI Accompaniment version: Beta 0.12 MMA is a accompaniment generator -- it creates midi tracks for a soloist to perform over from a user supplied file containing chords and MMA directives. MMA is very versatile and generates excellent tracks. It comes with an extensive user-extendable library with a variety of patterns for various popular rhythms, an extensive user manual, and several demo songs. MMA is a command line driven program. It creates MIDI files which need a sequencer or MIDI file play program. MMA is written in Python. You'll need Python 2.3 (or later) for MMA to function. MMA is supplied in 4 tar.gz archives. Included: mma-bin -- the main script and library files. mma-html -- documentation in HTML format. mma-pdf -- documentation in PDF format. mma-songs -- a collection of about 120 songs in MMA format. If you get all four download packages the total size is still less than 1.5 megabytes. MMA is currently in final BETAs. We are hoping for a 1.0 release early in 2005. Right now we need help in debugging the program, creating songs for distribution, and new and improved library files. Best of all, MMA is free. It is released under the terms of the GNU General Public License. It has been developed on a Linux platform, but should be usable on just about any system. A detailed page now exists on our web site on how-to install on a Windows system. MMA is available on my personal home page: http://mypage.uniserve.com/~bvdp/mma/mma.html If you have any questions or comments, please send them to: bvdp(a)uniserve.com Beta 0.12: Bass patterns expanded, minor improvements to Scale and Walk tracks, harmony improvements, a new MIDI INCLUDE directive, improved solo voice methods, and general cleanups/fixes. Comments appreciated! -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bvdp(a)uniserve.com WWW: http://mypage.uniserve.com/~bvdp

mxCGIPython - unofficial update for Python 2.4
by Oleg Broytmann 03 Dec '04

03 Dec '04

Hello! I patched mxCGIPython for Python 2.4: http://phd.pp.ru/Software/Python/misc/mxCGI/mxCGIPython.patch The patch adds 3 modules to Modules/Setup - zipimport, _symtable and _csv; it also adds CGIPython/pyversion.c to be used instead of python, becuase Makefile.cgi needs to know what version it is making before python interpreter is built. A script CGIPython/remove-modules is used in Makfile.cgi to remove modules from Modules/Setup to compile different versions of Python; this is probably bad approach, and it is not very portable; the script works on Linux and Solaris systems, but not on FreeBSD - it requires an option for sed (-E) and a slightly different regular expression - unescaped '+' instead of '\+'. Also there is a special patch for BSD that removes "unset" lines. Other than that minor problems the thing works fine. This is far from complete, of course, but that's all I can do. I rebuilt python 2.1.3, 2.2.3, 2.3.4 and 2.4.0 on Linux, Solaris 2.5.2, FreeBSD 4.9 and FreeBSD 5.3. The binaries are in the usual place: http://phd.pp.ru/Software/Python/misc/mxCGI/ Don't forget to make CGIPython/remove-modules executable. Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

ANN: IPython 0.6.5 is out
by Fernando Perez 01 Dec '04

01 Dec '04

Hi all, I'm glad to announce that IPython 0.6.5 is finally out. IPython's homepage is at: http://ipython.scipy.org and downloads are at: http://ipython.scipy.org/dist I've provided RPMs for Python 2.2 and 2.3, plus source downloads (.tar.gz and .zip). Debian, Fink and BSD packages for this version should be coming soon, as the respective maintainers (many thanks to Jack Moffit, Andrea Riciputi and Dryice Liu) have the time to follow their packaging procedures. Many thanks to Enthought for their continued hosting support for IPython, and to all the users who contributed ideas, fixes and reports. I'd promised that 0.6.4 would be the last version before the cleanup, but Prabhu Ramachandran managed to resucitate the GUI threading support which I'd worked on recently, but disabled after thinking it could not work. It turns out we were very close, and Prabhu did fix the remaining problems. Since this is a fairly significant improvement, I decided to make a release for it. In the process I added a few minor other things. *** WHAT is IPython? IPython tries to: 1. Provide an interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. 2. Serve as an embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. 3. Offer a flexible framework which can be used as the base environment for other systems with Python as the underlying language. *** NEW for this release: As always, the complete NEWS file can be found at http://ipython.scipy.org/NEWS, and the whole ChangeLog at http://ipython.scipy.org/ChangeLog. * Threading support for WXPython and pyGTK. It is now possible (with the -wthread and -gthread options) to control wx/gtk graphical interfaces from within an interactive ipython shell. Note that your wx/gtk libs need to be compiled with threading support for this to work. There is also experimental (but brittle) support for ALSO running Tkinter graphical interfaces alongside with wx or gtk ones. * New -d option to %run, for executing whole scripts with the interactive pdb debugger. This allows you to step, watch variables, set breakpoints, etc, without having to modify your scripts in any way. * Added filtering support for variable types to %who and %whos. You can now say 'whos function str' and whos will only list functions and strings, instead of all variables. Useful when working with crowded namespaces. (For some reason I forgot to document this in the ChangeLog). * Added ipython.el to the end-user distribution, for (X)Emacs support, since now the official python-mode.el from http://sourceforge.net/projects/python-mode has all the necessary fixes for ipython support (in CVS at this moment). * Other minor fixes and cleanups, both to code and documentation. Enjoy, and as usual please report any problems. Regards, Fernando.
