Hi.

Thank you for this script.

One thing that's missing is the import os statement:

Traceback (most recent call last):
  File "...pylint-recursive.py", line 40, in <module>
    BASE_DIRECTORY = os.getcwd()
NameError: name 'os' is not defined

Also, I'm using pylint 1.4.3 and Python 2.7.9 and when I run this script, I get the following error:

C:\working\env\Scripts\python.exe C:/working/pylint-recursive.py
['C:/working/pylint-recursive.py']
no directory specified, defaulting to current working directory
looking for *.py scripts in subdirectories of  C:\working
CHECKING  C:\working\config.py

    TOTAL += float(score)
ValueError: invalid literal for float(): 7.14/10 (previous run: 7.14/10, +0.00

Process finished with exit code 1

Any ideas?

Thank you.

I think it should be:
score = re.findall(r"(-?\d+\.\d+)", line)[0]

BUT how to generate the report The current script is just giving the ratre..

for me subprocess.Popen("pylint %s" % module, stdout=subprocess.PIPE).stdout.read() fails with OSError No such file or directory

Stacktrace
