There are breaking changes ahead!

We also have this 0.14 migration guide.

Features

• Breaking: removes flake8-executable, now using WPS452 instead of EXE001..EXE005
• Breaking: removes flake8-print, now using WPS421 instead of T001
• Breaking: removes flake8-builtins, now using WPS125 instead of A001..A005
• Breaking: removes flake8-annotations-complexity, now using WPS234 instead of TAE002
• Breaking: removes flake8-pep3101, now using WPS323 instead of S001, we also use a new logic for this violation: we check string defs for % patterns, and not for % operator
• Breaking: WPS441 is no longer triggered for except blocks, it is now handled by F821 from flake8
• Breaking: removes radon, because cognitive-complexity and mccabe is enough
• Breaking: removes flake8-loggin-format as a direct dependency
• Breaking: removes ImplicitTernaryViolation or WPS332, because it has too many false positives #1099
• Removes flake8-coding, all encoding strings, visitor and tests for old WPS323 which is now reused for modulo formatting checks
• Adds python3.8 support
• Changes styleguide.toml and flake8.toml scripts definition
• Extracts new violation - WPS450 from WPS436 #1118
• Adds domain names options: --allowed-domain-names and --forbidden-domain-names, that are used to create variable names' blacklist #1106
• Forbids to use \r (carriage return) as line breaks in strings #1111
• Forbids to use := operator, it now reuses WPS332 code
• Forbids to use positional only / arguments
• Forbids to have too many names imported from a single from ... import
• Forbids to use continue and break in finally
• Forbids to use __reduce__ and __reduce_ex__ magic methods
• Adds __call__ to list of methods that should be on top #1125
• Allows _ to be now used as a defined variable
• Removes cognitive_complexity dependency, now it is built in into our linter
• Adds baseline information for all complexity violation messages: x > baseline
• Changes how cognitive complexity is calculated
• Adds support for positional arguments in different checks
• Adds UnreadableNameViolation as WPS124 because there are some character combination which is not easy to read
• Adds support for NamedExpr with in compare type violation
