pylint-flask is Pylint plugin for improving code analysis when editing code using Flask. Inspired by pylint-django.

1. Recognize flask.ext.* style imports. Say you have the following code:

    from flask.ext import wtf
    from flask.ext.wtf import validators
    class PostForm(wtf.Form):
        content = wtf.TextAreaField('Content', validators=[validators.Required()])

   Normally, pylint will throw errors like:

    E:  1,0: No name 'wtf' in module 'flask.ext'
    E:  2,0: No name 'wtf' in module 'flask.ext'
    F:  2,0: Unable to import 'flask.ext.wtf'
   

   As pylint builds it's own abstract syntax tree, pylint-flask will translate the flask.ext imports into the actual module name, so pylint can continue checking your code.

Ensure pylint-flask is installed and on your path, and then run pylint using pylint-flask as a plugin.

pip install pylint-flask
pylint --load-plugins pylint_flask [..your module..]

Pull requests are always welcome. Here's an outline of the steps you need to prepare your code.

1. git clone https://github.com/jschaf/pylint-flask.git
2. cd pylint-flask
3. mkvirtualenv pylint-flask
4. pip install -r dev-requirements.txt
5. git checkout -b MY-NEW-FIX
6. Hack away
7. Make sure everything is green by running tox
8. git push origin MY-NEW-FIX
9. Create a pull request
