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 from 0.7.5 to 0.8: * Add check for accessing list as list[1,2], should be slice 1:2 * Add -J/maxargs to warn when using too many arguments * Add -K/maxlocals to warn when using too many local variables * Add -D/intdivide to warn when using integer division * Add -O/objattrs to warn when using object.attribute that doesn't exist * Add -M/reimportself to warn when a module imports itself * Add -E/unusednames to provide a list of unused names to ignore (default is: [ '_', 'empty', 'unused' ]) * Major refactoring of warn.py -> utils, msgs, Warning, CodeChecks * Fix spurious warnings for No class attribute for dynamic classes * Fix spurious warnings when using objects from blacklisted modules (Instantiating object with arguments, but no constructor, etc) * Fix spurious warnings when using lambdas * Fix spurious warning (No global Y) when using: from X import Y (problem in python 1.5/1.6 only) In case you missed 0.7.5, here's the change Log from 0.7 to 0.7.5: * Suppress warnings on a per module/function/class/method basis with new suppressions = {} in .pycheckrc * Suppress warnings by setting __pychecker__ in source code * Change long argument behaviour --arg sets arg to true, --no-arg sets arg to false (also works for warning suppression) * Add -U/--reuseattr check if function/class/method names are reused * Add -T/--argsused check for unused method/function arguments * Add -G/--selfused ignore if self is unused in a method (requires --argsused) * Add -q/--stdlib to disable warnings from the standard library * Add -o/--override warning when a method has different signature than one being overridden in a base class * Add -F/--rcfile to generate a .pycheckrc file * Fix checking files in standard library before local file * Fix spurious warning when using from X import Y and imports in methods (Module (m) re-imported) * Fix spurious warning when doing: from X import Y, Z * Fix spurious warning when deriving from Exception() and instantiating object with multiple arguments * Fix method argument checks when calling base class methods * Fix error msg to base constructors (msg count was wrong) * Fix access to builtin module attributes (e.g., sys.exc_value) generating 'No attribute warnings' * Fix tests (forgot to add : after line number in expected results) PyChecker is available on Source Forge: Web page: http://pychecker.sourceforge.net/ Project page: http://sourceforge.net/projects/pychecker/ Neal -- pychecker@metaslash.com
