+:mod:`rlcompleter` --- Completion function for GNU readline
+===========================================================
+
+.. module:: rlcompleter
+ :synopsis: Python identifier completion, suitable for the GNU readline library.
+.. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
+
+
+The :mod:`rlcompleter` module defines a completion function suitable for the
+:mod:`readline` module by completing valid Python identifiers and keywords.
+
+When this module is imported on a Unix platform with the :mod:`readline` module
+available, an instance of the :class:`Completer` class is automatically created
+and its :meth:`complete` method is set as the :mod:`readline` completer.
+
+Example::
+
+ >>> import rlcompleter
+ >>> import readline
+ >>> readline.parse_and_bind("tab: complete")
+ >>> readline. <TAB PRESSED>
+ readline.__doc__ readline.get_line_buffer( readline.read_init_file(
+ readline.__file__ readline.insert_text( readline.set_completer(
+ readline.__name__ readline.parse_and_bind(
+ >>> readline.
+
+The :mod:`rlcompleter` module is designed for use with Python's interactive
+mode. A user can add the following lines to his or her initialization file
+(identified by the :envvar:`PYTHONSTARTUP` environment variable) to get
+automatic :kbd:`Tab` completion::
+
+ try:
+ import readline
+ except ImportError:
+ print "Module readline not available."
+ else:
+ import rlcompleter
+ readline.parse_and_bind("tab: complete")
+
+On platforms without :mod:`readline`, the :class:`Completer` class defined by
+this module can still be used for custom purposes.

+Completer Objects
+-----------------
+
+Completer objects have the following method:
+
+
+.. method:: Completer.complete(text, state)
+
+ Return the *state*th completion for *text*.
+
+ If called for *text* that doesn't include a period character (``'.'``), it will
+ complete from names currently defined in :mod:`__main__`, :mod:`__builtin__` and
+ keywords (as defined by the :mod:`keyword` module).
+
+ If called for a dotted name, it will try to evaluate anything without obvious
+ side-effects (functions will not be evaluated, but it can generate calls to
+ :meth:`__getattr__`) up to the last part, and find matches for the rest via the
+ :func:`dir` function. Any exception raised during the evaluation of the
+ expression is caught, silenced and :const:`None` is returned.
