Install pep8 module:
|
|
$ easy_install pep8
|
|
or
|
|
$ pip install pep8
|
|
|
|
To add the pep8 tool to the waf file:
|
|
$ ./waf-light --tools=compat15,pep8
|
|
or, if you have waf >= 1.6.2
|
|
$ ./waf update --files=pep8
|
|
|
|
|
|
Then add this to your wscript:
|
|
|
|
[at]extension('.py', 'wscript')
|
|

|
|
self.create_task('Pep8', node)
