Checker Classes
---------------

The :class:`StyleGuide` class is used to configure a style guide checker
instance to check multiple files.

The :class:`Checker` class can be used to check a single file.


.. autoclass:: StyleGuide(parse_argv=False, config_file=None, parser=None, paths=None, report=None, **kwargs)

   .. automethod:: init_report(reporter=None)
   .. automethod:: check_files(paths=None)
   .. automethod:: input_file(filename, lines=None, expected=None, line_offset=0)
   .. automethod:: input_dir(dirname)
   .. automethod:: excluded(filename, parent=None)
   .. automethod:: ignore_code(code)
   .. automethod:: get_checks(argument_name)

.. autoclass:: Checker(filename=None, lines=None, report=None, **kwargs)

   .. automethod:: readline
   .. automethod:: run_check(check, argument_names)
   .. automethod:: check_physical(line)
   .. automethod:: build_tokens_line
   .. automethod:: check_logical
   .. automethod:: check_ast
   .. automethod:: generate_tokens
   .. automethod:: check_all(expected=None, line_offset=0)

Utilities
---------

.. autofunction:: expand_indent(line)
.. autofunction:: mute_string(text)
.. autofunction:: read_config(options, args, arglist, parser)
.. autofunction:: process_options(arglist=None, parse_argv=False, config_file=None)
.. autofunction:: register_check(func_or_cls, codes=None)

..
  These ones are used internally, but they don't need advertising
  .. autofunction:: readlines(filename)
