Previously, pycodestyle never introspected the argument names for
classes except to require that ``tree`` be an argument it could pass.
For Flake8 3.0, we lifted that restriction, but old plugins seem to
have cargo-culted their __init__ signature to be
def __init__(self, tree, builtins=None):
For some yet unknown reason. This was causing an AttributeError. By
updating flake8.utils.parameters_for to return a dictionary that
indicates whether the parameter is required or not, we can side-step
this by simply ignoring the parameter if it has a default value and
we cannot provide it.
Closes#151
This relies on two things:
1. Properly configuring flake8-import-order to use that style
2. Properly configuring flake8-import-order to know that flake8 is our
application name.
- Add more documentation around utils functions
- Fix documentation about default formatting plugins
- Add extra documentation of filenames_from predicate parameter
- Add test for the default parameter of flake8.utils.fnmatch
Flake8 and pep8 has historically supported three types of checks:
- Plugins that accept the physical line
- Plugins that accept the logical line
- Plugins that accept the AST tree
The logical place to make this distinction is on the Checkers plugin
type manager class. This adds the foundation for finding plugins that
fall into each class.
We add utils.fnmatch and utils.filenames_for in anticipation of our
checker manager creating file checkers for each file. We also include
tests for these functions and a couple previously untested utility
functions.
Add parse_comma_separated_list, normalize_path, and normalize_paths and
add logic in OptionManager.parse_args to use the right normalize_path*
function based on comma_separated_list value of the option.
