PyGtk, PyGtkGlExt Windows all in one installer
by Marco Bonifazi April 6, 2008

April 6, 2008

I realized a PyGtk all in one installer for Windows. You can download it from here: http://www.bonifazi.eu/appunti/pygtk_windows_installer.exe It is simply an assembling of all the different installers I previously downloaded (which are executed step by step), and you can choose. I realized this installer using EclipseNSIS and compiling the script generated by NSIS. Then, the script I created and that you can compile and modify using NSIS is the following: http://www.bonifazi.eu/appunti/pygtk_windows_installer.nsi I give also the links of the webpages where I got the different installers: http://www.bonifazi.eu/appunti/2008/04/pygtk-all-in-one-installer.html I'll try to keep update this installer. I hope it could be useful to someone. Bye. Marco Bonifazi

musync 0.3 beta
by John-John Tedro April 2, 2008

April 2, 2008

Musync is an command-line interface tagger which uses mutagen to read meta data from music-files, and tries to create a sane file structure from the collected tags. It utilizes sub processing for file handling which enables it to execute practically any command desirable. It's weakness is that it relies on the files meta data to be correct so you must manually tag all the files beforehand. This is not a feature planned in future releases. Use an external program like PicardTagger for this purpose. Musync is not an interactive tool, it will never prompt for anything but try to make intelligent choices from the arguments received at execution. I'm in desperate need of third party testers to try this out for errors, and hoped there were someone interested in slaughtering their music-library for the sake of organization. I use this tool myself, since i find gui-apps annoying and haven't found a reasonable alternative to this. theres also instructions on how to get a snapshot (using svn), but I've also created a small http-wrapper so you can download the snapshot in a .tar.gz. read more at: http://trac.ostcon.org/trac/wiki/MuSync 0.3 Beta is just an internal version count, don't take it too seriously a.t.m. It could just as-well be called r450. Have fun with my blood and tears. Cheers, John-John * the original though of musync was to sync DAP's (digital audio players) with a music library, which it still does marvelously. That and a bit more.

CodeInvestigator 0.8.0
by Martien Friedeman April 1, 2008

April 1, 2008

CodeInvestigator version 0.8.0 was released on April 02. A usability change was made: A user's Python files are listed in the Files screen. The directory/directories for these files is specified in the Settings screen. A user now has an additional way to change this: Clicking the directory name in the Files screen. CodeInvestigator is a tracing tool for Python programs. Running a program through CodeInvestigator creates a recording. Program flow, function calls, variable values and conditions are all stored for every line the program executes. The recording is then viewed with an interface consisting of the code. The code can be clicked: A clicked variable displays its value, a clicked loop displays its iterations. You read code, and have at your disposal all the run time details of that code. A computerized desk check tool and another way to learn about your program. http://sourceforge.net/project/showfiles.php?group_id=183942
