CodeInvestigator version 0.13.0 was released on June 24.

Bug fix: Changes to imported files were not taken into account.

This version only works with Python 2.6. Some modules disappear in Python 3.0 and this version has these modules replaced.

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.
