Crash when using regular expressions

[tomascapek]

I created a simple rule from which I expected to fail on every single file in my project:

settings:
  all_files: &all_files !settings
    included:
      - ~+/*
    excluded:
      - ~+/.tox/*
    allow_ignore: yes

default_settings: *all_files

rules:
  SimpleRule:
    description: "Simple rule"
    expr: !regex .*

And then I launched it:

bellybutton lint

Which results in a crash:

Traceback (most recent call last):
  File "/home/dev_intern/.virtualenvs/bellybutton-test/bin/bellybutton", line 11, in <module>
    sys.exit(main())
  File "/home/dev_intern/.virtualenvs/bellybutton-test/lib/python3.5/site-packages/bellybutton/cli.py", line 203, in main
    for arg in args.func.__code__.co_varnames[:args.func.__code__.co_argcount]

    linting_results = list(lint_file(filepath, file_contents, rules))
  File "/home/dev_intern/.virtualenvs/bellybutton-test/lib/python3.5/site-packages/bellybutton/linting.py", line 65, in lint_file
    for match in re.finditer(rule.expr)
TypeError: finditer() missing 1 required positional argument: 'string'

Can this be fixed soon?

Hello @tomascapek , thanks for raising this. The bug you described should now be fixed in the latest release (v.2.2). Would you mind having a look to verify? Thanks again!
