Pyflakes
|
||
|
|
========
|
||
|
|
|
||
|
|
A simple program which checks Python source files for errors.
|
||
|
|
|
||
|
|
Pyflakes analyzes programs and detects various errors. It works by
|
||
|
|
parsing the source file, not importing it, so it is safe to use on
|
||
|
|
modules with side effects. It's also much faster.
|
||
|
|
|
||
|
|
It is `available on PyPI <https://pypi.org/project/pyflakes/>`_
|
||
|
|
and it supports all active versions of Python: 2.7 and 3.4 to 3.7.
|
||
|
|
|
||
|
|
|
||
|
|
|
||

|
Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
It can be installed with::
|
||
|
|
|
||
|
|
$ pip install --upgrade pyflakes
|
||
|
|
|
||
|
|
|
||
|
|
Useful tips:
|
||
|
|
|
||
|
|
* Be sure to install it for a version of Python which is compatible
|
||
|
|
with your codebase: for Python 2, ``pip2 install pyflakes`` and for
|
||
|
|
Python3, ``pip3 install pyflakes``.
|
||
|
|
|
||
|
|
* You can also invoke Pyflakes with ``python3 -m pyflakes .`` or
|
||
|
|
``python2 -m pyflakes .`` if you have it installed for both versions.
|
||
|
|
|
||
|
|
* If you require more options and more flexibility, you could give a
|
||
|
|
look to Flake8_ too.

Design Principles
|
||
|
|
-----------------
|
||
|
|
Pyflakes makes a simple promise: it will never complain about style,
|
||
|
|
and it will try very, very hard to never emit false positives.
|
||
|
|
|
||
|
|
Pyflakes is also faster than Pylint_
|
||
|
|
or Pychecker_. This is
|
||
|
|
largely because Pyflakes only examines the syntax tree of each file
|
||
|
|
individually. As a consequence, Pyflakes is more limited in the
|
||
|
|
types of things it can check.
|
||
|
|
|
||
|
|
If you like Pyflakes but also want stylistic checks, you want
|
||
|
|
flake8_, which combines
|
||
|
|
Pyflakes with style checks against
|
||
|
|
`PEP 8`_ and adds
|
||
|
|
per-project configuration ability.

Contributing
|
||
|
|
------------
|
||
|
|
|
||
|
|
Issues are tracked on `GitHub <https://github.com/PyCQA/pyflakes/issues>`_.
|
||
|
|
|
||
|
|
Patches may be submitted via a `GitHub pull request`_ or via the mailing list
|
||
|
|
if you prefer. If you are comfortable doing so, please `rebase your changes`_
|
||
|
|
so they may be applied to master with a fast-forward merge, and each commit is
|
||
|
|
a coherent unit of work with a well-written log message. If you are not
|
||
|
|
comfortable with this rebase workflow, the project maintainers will be happy to
|
||
|
|
rebase your commits for you.
|
||
|
|
|
||
|
|
All changes should include tests and pass flake8_.
