Hello, I'm happy to announce the release of Pylint 1.4.2 and astroid 1.3.5. The following changes were included in these releases: For pylint: * Don't require a docstring for empty modules. Closes issue #261. * Fix a false positive with `too-few-format-args` string warning, emitted when the string format contained a normal positional argument ('{0}'), mixed with a positional argument which did an attribute access ('{0.__class__}'). Closes issue #463. * Take in account all the methods from the ancestors when checking for too-few-public-methods. Closes issue #471. * Catch enchant errors and emit 'invalid-characters-in-docstring' when checking for spelling errors. Closes issue #469. * Use all the inferred statements for the super-init-not-called check. Closes issue #389. * Add a new warning, 'unichr-builtin', emitted by the Python 3 porting checker, when the unichr builtin is found. Closes issue #472. * Add a new warning, 'intern-builtin', emitted by the Python 3 porting checker, when the intern builtin is found. Closes issue #473. * Add support for editable installations. * The HTML output accepts the `--msg-template` option. Patch by Dan Goldsmith. * Add 'map-builtin-not-iterating' (replacing 'implicit-map-evaluation'), 'zip-builtin-not-iterating', 'range-builtin-not-iterating', and 'filter-builtin-not-iterating' which are emitted by `--py3k` when the appropriate built-in is not used in an iterating context (semantics taken from 2to3). * Add a new warning, 'unidiomatic-typecheck', emitted when an explicit typecheck uses type() instead of isinstance(). For example, `type(x) == Y` instead of `isinstance(x, Y)`. Patch by Chris Rebert. Closes issue #299. * Add support for combining the Python 3 checker mode with the --jobs flag (--py3k and --jobs). Closes issue #467. * Add a new warning for the Python 3 porting checker, 'using-cmp-argument', emitted when the `cmp` argument for the `list.sort` or `sorted builtin` is encountered. * Make the --py3k flag commutative with the -E flag. Also, this patch fixes the leaks of error messages from the Python 3 checker when the errors mode was activated. Closes issue #437. For astroid: * Add the ability to optimize small ast subtrees, with the first use in the optimization of multiple BinOp nodes. This removes recursivity in the rebuilder when dealing with a lot of small strings joined by the addition operator. Closes issue #59. * Obtain the methods for the nose brain tip through an unittest.TestCase instance. Closes Pylint issue #457. * Fix a crash which occurred when a class was the ancestor of itself. Closes issue #78. * Improve the scope_lookup method for Classes regarding qualified objects, with an attribute name exactly as one provided in the class itself. For example, a class containing an attribute 'first', which was also an import and which had, as a base, a qualified name or a Gettattr node, in the form 'module.first', then Pylint would have inferred the `first` name as the function from the Class, not the import. Closes Pylint issue #466. * Implement the assigned_stmts operation for Starred nodes, which was omitted when support for Python 3 was added in astroid. Closes issue #36. If you find any bugs, don't hesitate to open a new issue on our issue tracker. Enjoy!
