+
+Fixers
+------
+
+Each step of tranforming code is encapsulated in a fixer.  The command ``2to3
+-l`` lists them.  As :ref:`documented above <2to3-using>`, each can be turned on
+and off individually.  They are described here in more detail.
+
+
+.. 2to3fixer:: apply
+
+   Removes usage of :func:`apply`.  For example ``apply(function, *args,
+   **kwargs)`` is converted to ``function(*args, **kwargs)``.
+
+.. 2to3fixer:: basestring
+
+   Converts :class:`basestring` to :class:`str`.
+
+.. 2to3fixer:: buffer
+
+   Converts :class:`buffer` to :class:`memoryview`.  This fixer is optional
+   because the :class:`memoryview` API is similar but not exactly the same as
+   that of :class:`buffer`.
+
+.. 2to3fixer:: callable
+
+   Converts ``callable(x)`` to ``hasattr(x, "__call_")``.
+
+.. 2to3fixer:: dict
+
+   Fixes dictionary iteration methods.  :meth:`dict.iteritems` is converted to
+   :meth:`dict.items`, :meth:`dict.iterkeys` to :meth:`dict.keys`, and
+   :meth:`dict.itervalues` to :meth:`dict.values`.  It also wraps existing
+   usages of :meth:`dict.items`, :meth:`dict.keys`, and :meth:`dict.values` in a
+   call to :class:`list`.
+
+.. 2to3fixer:: except
+
+   Converts ``except X, T`` to ``except X as T``.
+
+.. 2to3fixer:: exec
+
+   Converts the :keyword:`exec` statement to the :func:`exec` function.
+
+.. 2to3fixer:: execfile
+
+   Removes usage of :func:`execfile`.  The argument to :func:`execfile` is
+   wrapped in calls to :func:`open`, :func:`compile`, and :func:`exec`.
+
+.. 2to3fixer:: filter
+
+   Wraps :func:`filter` usage in a :class:`list` call.
+
+.. 2to3fixer:: funcattrs
+
+   Fixes function attributes that have been renamed.  For example,
+   ``my_function.func_closure`` is converted to ``my_function.__closure__``.
+
+.. 2to3fixer:: future
+
+   Removes ``from __future__ import new_feature`` statements.
+
+.. 2to3fixer:: getcwdu
+
+   Renames :func:`os.getcwdu` to :func:`os.getcwd`.
+
+.. 2to3fixer:: has_key
+
+   Changes ``dict.has_key(key)`` to ``key in dict``.
+
+.. 2to3fixer:: idioms
+
+   This optional fixer preforms several transformations that make Python code
+   more idiomatic.  Type comparisions like ``type(x) is SomeClass`` and
+   ``type(x) == SomeClass`` are converted to ``isinstance(x, SomeClass)``.
+   ``while 1`` becomes ``while True``.  This fixer also tries to make use of
+   :func:`sorted` in appropiate places.  For example, this block ::
+
+       L = list(some_iterable)
+       L.sort()
+
+   is changed to ::
+
+      L = sorted(some_iterable)
+
+.. 2to3fixer:: import
+
+   Detects sibling imports and converts them to relative imports.
+
+.. 2to3fixer:: imports
+
+   Handles module renames in the standard library.
+
+.. 2to3fixer:: imports2
+
+   Handles other modules renames in the standard library.  It is separate from
+   the :2to3fixer:`imports` fixer only because of technical limitations.
+
+.. 2to3fixer:: input
+
+   Converts ``input(prompt)`` to ``eval(input(prompt))``
+
+.. 2to3fixer:: intern
+
+   Converts :func:`intern` to :func:`sys.intern`.
+
+.. 2to3fixer:: isinstance
+
+   Fixes duplicate types in the second argument of :func:`isinstance`.  For
+   example, ``isinstance(x, (int, int))`` is converted to ``isinstance(x,
+   (int))``.
+
+.. 2to3fixer:: itertools_imports
+
+   Removes imports of :func:`itertools.ifilter`, :func:`itertools.izip`, and
+   :func:`itertools.imap`.  Imports of :func:`itertools.ifilterfalse` are also
+   changed to :func:`itertools.filterfalse`.
+
+.. 2to3fixer:: itertools
+
+   Changes usage of :func:`itertools.ifilter`, :func:`itertools.izip`, and
+   :func:`itertools.imap` to their builtin equivalents.
+   :func:`itertools.ifilterfalse` is changed to :func:`itertools.filterfalse`.
+
+.. 2to3fixer:: long
+
+   Strips the ``L`` prefix on long literals and renames :class:`long` to
+   :class:`int`.
+
+.. 2to3fixer:: map
+
+   Wraps :func:`map` in a :class:`list` call.  It also changes ``map(None, x)``
+   to ``list(x)``.  Using ``from future_builtins import map`` disables this
+   fixer.
+
+.. 2to3fixer:: metaclass
+
+   Converts the old metaclass syntax (``__metaclass__ = Meta`` in the class
+   body) to the new (``class X(metaclass=Meta)``).
+
+.. 2to3fixer:: methodattrs
+
+   Fixes old method attribute names.  For example, ``meth.im_func`` is converted
+   to ``meth.__func__``.
+
+.. 2to3fixer:: ne
+
+   Converts the old not-equal syntax, ``<>``, to ``!=``.
+
+.. 2to3fixer:: next
+
+   Converts the use of iterator's :meth:`next` methods to the :func:`next`
+   function.  It also renames :meth:`next` methods to :meth:`~object.__next__`.
+
+.. 2to3fixer:: nonzero
+
+   Renames :meth:`~object.__nonzero__` to :meth:`~object.__bool__`.
+
+.. 2to3fixer:: numliterals
+
+   Converts octal literals into the new syntax.
+
+.. 2to3fixer:: paren
+
+   Add extra parenthesis where they are required in list comprehensions.  For
+   example, ``[x for x in 1, 2]`` becomes ``[x for x in (1, 2)]``.
+
+.. 2to3fixer:: print
+
+   Converts the :keyword:`print` statement to the :func:`print` function.
+
+.. 2to3fixer:: raises
+
+   Converts ``raise E, V`` to ``raise E(V)``, and ``raise E, V, T`` to ``raise
+   E(V).with_traceback(T)``.  If ``E`` is a tuple, the translation will be
+   incorrect because substituting tuples for exceptions has been removed in 3.0.
+
+.. 2to3fixer:: raw_input
+
+   Converts :func:`raw_input` to :func:`input`.
+
+.. 2to3fixer:: reduce
+
+   Handles the move of :func:`reduce` to :func:`functools.reduce`.
+
+.. 2to3fixer:: renames
+
+   Changes :data:`sys.maxint` to :data:`sys.maxsize`.
+
+.. 2to3fixer:: repr
+
+   Replaces backtick repr with the :func:`repr` function.
+
+.. 2to3fixer:: set_literal
+
+   Replaces use of the :class:`set` constructor with set literals.  This fixer
+   is optional.
+
+.. 2to3fixer:: standard_error
+
+   Renames :exc:`StandardError` to :exc:`Exception`.
+
+.. 2to3fixer:: sys_exc
+
+   Changes the deprecated :data:`sys.exc_value`, :data:`sys.exc_type`,
+   :data:`sys.exc_traceback` to use :func:`sys.exc_info`.
+
+.. 2to3fixer:: throw
+
+   Fixes the API change in generator's :meth:`throw` method.
+
+.. 2to3fixer:: tuple_params
+
+   Removes implicit tuple parameter unpacking.  This fixer inserts temporary
+   variables.
+
+.. 2to3fixer:: types
+
+   Fixes code broken from the removal of some members in the :mod:`types`
+   module.
+
+.. 2to3fixer:: unicode
+
+   Renames :class:`unicode` to :class:`str`.
+
+.. 2to3fixer:: urllib
+
+   Handles the rename of :mod:`urllib` and :mod:`urllib2` to the :mod:`urllib`
+   package.
+
+.. 2to3fixer:: ws_comma
+
+   Removes excess whitespace from comma separated items.  This fixer is
+   optional.
+
+.. 2to3fixer:: xrange
+
+   Renames :func:`xrange` to :func:`range` and wraps existing :func:`range`
+   calls with :class:`list`.
+
+.. 2to3fixer:: xreadlines
+
+   Changes ``for x in file.xreadlines()`` to ``for x in file``.
+
+.. 2to3fixer:: zip
+
+   Wraps :func:`zip` usage in a :class:`list` call.  This is disabled when
+   ``from future_builtins import zip`` appears.
