Startup of the project - code analyser

my colleague resigned last month

since then i have been suffering ... with the 25k un-documented lines of codes from him

and it is IronPython codes ... no debuggers ... hand coded UI ...


writing codes that runs is not sexy, writing codes that could be easily understood by others is real sexy

i need a tool to evaluate the code quality



my code analyser is supposed to take a bunch of source codes
and then to give a sophisticated statistical information about the codes

1. lines of codes
2. lines of comments
3. function length
4. class length
5. dependency level
6. variable names analytical info
7. ...
   

so that we can somewhat roughly know the programming style of a developer
