A new version of PyChecker is available for your hacking pleasure.
PyChecker is a tool for finding common bugs in python source code.
It finds problems that are typically caught by a compiler for less
dynamic languages, like C and C++.
Comments, criticisms, new ideas, and other feedback is welcome.
Change Log:
* Improve import warning messages, add from ... import ... checks
* checker.py -h prints defaults after processing .pycheckrc file
* Add config option -k/--pkgimport to disable unused imports from __init__.py
* Add warning for variable used before being set
* Improve format string checks/warnings
* Check arguments to constructors
* Check that self is first arg to base constructor
* Add -e/--errors option to only warn about likely errors
* Make 'self' configurable as the first argument to methods
* Add check that there is a c'tor when instantiating an object and
passing arguments
* Add config option (-N/--initreturn) to turn off warnings
when returning None from __init__()
* Fix internal error with python 2.1 which defines a new op: LOAD_DEREF
* Check in lambda functions for module/variable use
* Fix inability to evaluate { 1: 'a' } inline,
led to incorrect __init__() not called warnings
* Fix exception when class overrides __special__() methods & raise exception
* Fix check in format strings when using '%*g %*.*g', etc
* Add check for static class attributes
* Fix checking of module attributes
* Fix wrong filename in 'Base class (xxx) __init__() not called'
when doing a from X import *
* Fix 'No attribute found' for very dynamic classes
(may also work for classes that use __getattr__)
