I was finally able to get version 0.5 out. Just in case this is the first time you are seeing this message, or you forgot what PyChecker is:
PyChecker is a tool for finding common bugs in python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C++. Because of the dynamic nature of python, some warnings may be incorrect; however, spurious warnings should be fairly infrequent.
The highlights are that code at the module scope is now checked. There is still a problem with class variables and globals that are default parameter values. But other than that, there should be no more spurious Variable unused warnings.
Code that makes PyChecker raise an exception should now be caught in most cases and this produces a warning. Please mail me if you find it blowing up on your code. The last line processed is shown in the warning, so if you include some context, I can hopefully fix the problem.
Also, PyChecker should really use the files passed on the command line, even if it uses the same module name internally. So it will check your warn.py, not PyChecker's warn.py.
Feedback, comments, criticisms, new ideas, better ideas, etc. are all greatly appreciated. Thanks for everyone who has taken the time to mail me. If you can think of common mistakes that are made that PyChecker doesn't find, please let me know.
Here's the CHANGELOG:
