ikaaro 0.20.2 released
by "J. David Ibáñez" Jan. 21, 2008

Jan. 21, 2008

This is a Content Management System built on Python & itools, among other features ikaaro provides: - content and document management (index&search, metadata, etc.) - multilingual user interfaces and content - high level modules: wiki, forum, tracker, etc. This release brings a few new features. The new events log (log/events) keeps information about the database activity. The debug log has been removed, and now debugging data is recorded in the events log. The tracker has a new field named "CC", so any user in the "CC" list will be notified with an email every time the issue changes. There are three new views: "backlinks", "orphans" and "broken_links". Useful for maintenance purposes, these views leverage the mechanism for referencial integrity introduced in the previous release. Many bugs have been fixed, including #108, #205, #207, #215, #222, #224, #225, #227, #228, #230, #231, #238, #239 and #240.

CodeInvestigator version 0.7.0
by Martien Friedeman Jan. 16, 2008

Jan. 16, 2008

CodeInvestigator version 0.7.0 was released on January 17. A new feature was added: CodeInvestigator helps you return to your code after you have scrolled away from it. Lines are marked so you can locate them and scroll back to them. Lines are marked after you have looked at them for at least 3 seconds. You can adjust this period in 'Settings'. CodeInvestigator is a tracing tool for Python programs. Running a program trough 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
