pylint 1.3.0

python code static checker

Latest Version: 1.5.0

Pylint is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells (as defined in Martin Fowler’s Refactoring book).

Pylint has many rules enabled by default, way too much to silence them all on a minimally sized program. It’s highly configurable and handle pragmas to control it from within your code. Additionally, it is possible to write plugins to add your own checks.

It’s a free software distributed under the GNU Public Licence.

Development is hosted on bitbucket:

Pylint requires the astroid (the later the better; formerly known as logilab-astng) and logilab-common (version >= 0.53) packages.

From the source distribution, extract the tarball and run

python install

You’ll have to install dependencies in a similar way. For debian and rpm packages, use your usual tools according to your Linux distribution.

More information about installation and available distribution format may be found in the user manual in the doc subdirectory.
