| What's New in Pylint 2.8 |
| ************************** |
| |
| :Release: 2.8 |
| :Date: 2021-04-24 |
| |
| Summary -- Release highlights |
| ============================= |
| |
| Breaking changes |
| ================ |
| |
| * The 'doc' extra-require has been removed. `__pkginfo__`` does not contain the package metadata anymore |
| (except ``numversion``, until 3.0). Meta-information are accessible with |
| |
| ```python |
| from importlib import metadata |
| metadata.metadata('pylint') |
| ``` |
| Prefer that to an import from ``__pkginfo__``. |
| |
| New checkers |
| ============ |
| |
| * New refactoring message ``consider-using-with``. This message is emitted if resource-allocating functions or methods of the |
| standard library (like ``open()`` or ``threading.Lock.acquire()``) that can be used as a context manager are called without |
| a ``with`` block. |
| |
| * Add ``deprecated-argument`` check for deprecated arguments. |
| |
| * Add new extension ``ConfusingConsecutiveElifChecker``. This optional checker emits a refactoring message (R5601 ``confusing-consecutive-elif``) |
| if if/elif statements with different indentation levels follow directly one after the other. |
| |
| * Add ``consider-using-min-max-builtin`` check for if statement which could be replaced by Python builtin min or max. |
| |
| * Add new extension ``TypingChecker``. This optional checker can detect the use of deprecated typing aliases |
| and can suggest the use of the alternative union syntax where possible. |
| (For example, 'typing.Dict' can be replaced by 'dict', and 'typing.Unions' by '|', etc.) |
| Make sure to check the config options if you plan on using it! |
| |
| * Add ``deprecated-class`` check for deprecated classes. |
| |
| Other Changes |
| ============= |
| |
| * New option ``--output=<file>`` to output result to a file rather than printing to stdout. |
| |
| Closes #1070 |
| |
| * Reduce usage of blacklist/whitelist terminology. Notably, ``extension-pkg-allow-list`` is an |
| alternative to ``extension-pkg-whitelist`` and the message ``blacklisted-name`` is now emitted as |
| ``disallowed-name``. The previous names are accepted to maintain backward compatibility. |
| |
| * The packaging is now done via setuptools exclusively. ``doc``, ``tests``, ``man``, ``elisp`` and ``Changelog`` are |
| not packaged anymore - reducing the size of the package by 75%. |
| |
| * Updated ``astroid`` to 2.5.4 |
| |
| * COPYING has been renamed to LICENSE for standardization. |
