CodeInvestigator version 0.10.0 was released on April 28. This release fixes 2 bugs: Exceptions were not handled correctly. Recursive programs were not handled correctly. Thank you Sze Meng for reporting these! A usability change was made: Until now you could only go to a specific iteration by clicking the '>>' tab. This becomes a nuisance when there are many iterations. Now, when there are many iterations to choose from, you can click a selection tab that allows you to jump. 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
