Overview

========

**pydiatra** is yet another static checker for Python code.

Implemented checks

==================

* embedded code copies

* ``except`` shadowing builtins

  (e.g. ``except IOError, OSError:``, which overwrites ``OSError``)

* bare ``except``

  (i.e. ``except:``)

* hardcoded errno values

  (e.g. ``exc.errno == 2`` instead of ``exc.errno == errno.ENOENT``)

* inconsistent use of tabs and spaces in indentation

* ``mkstemp()`` file descriptor leaks

  (e.g. ``path = tempfile.mkstemp()[1]``)

* obsolete PIL imports

  (e.g. ``import Image`` instead of ``from PIL import Image``)

* regular expression syntax errors

* misplaced flags arguments in

  ``re.split()``, ``re.sub()``, ``re.subn()``

* dubious or deprecated constructs in regular expressions:

  * duplicate range

    (e.g. ``re.compile("[aa]")``)

  * overlapping ranges

    (e.g. ``re.compile("[a-zA-z]")``)

  * bad escape sequences

    (e.g. ``re.compile(r"\eggs")``)

  * misplaced inline flags

    (e.g. ``re.compile("eggs(?i)")``; Python 3.6+ only)

  * combining incompatible flags

  * redundant flags

* string exceptions

  (e.g. ``raise "eggs"`` or ``except "ham":``)

* string formatting errors

* comparisons with ``sys.version`` or ``sys.hexversion``

* Python syntax errors

* Python syntax warnings

  * assertions that are always true

  * syntactic constructs that are no longer supported in Python 3

  * ill-formed assignments to global variables

  * use of ``async`` and ``await`` as names

  * invalid escape sequences in strings

    (Python 3.6+ only)

See the manual page for details.

Prerequisites

=============

* Python 2.7 or 3.2+

* futures_ (needed only for Python 2.X)
