晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

:mod:`modulefinder` --- Find modules used by a script
=====================================================

.. module:: modulefinder
   :synopsis: Find modules used by a script.
.. sectionauthor:: A.M. Kuchling <amk@amk.ca>


.. versionadded:: 2.3

**Source code:** :source:`Lib/modulefinder.py`

--------------

This module provides a :class:`ModuleFinder` class that can be used to determine
the set of modules imported by a script. ``modulefinder.py`` can also be run as
a script, giving the filename of a Python script as its argument, after which a
report of the imported modules will be printed.


.. function:: AddPackagePath(pkg_name, path)

   Record that the package named *pkg_name* can be found in the specified *path*.


.. function:: ReplacePackage(oldname, newname)

   Allows specifying that the module named *oldname* is in fact the package named
   *newname*.  The most common usage would be  to handle how the :mod:`_xmlplus`
   package replaces the :mod:`xml` package.


.. class:: ModuleFinder([path=None, debug=0, excludes=[], replace_paths=[]])

   This class provides :meth:`run_script` and :meth:`report` methods to determine
   the set of modules imported by a script. *path* can be a list of directories to
   search for modules; if not specified, ``sys.path`` is used.  *debug* sets the
   debugging level; higher values make the class print  debugging messages about
   what it's doing. *excludes* is a list of module names to exclude from the
   analysis. *replace_paths* is a list of ``(oldpath, newpath)`` tuples that will
   be replaced in module paths.


   .. method:: report()

      Print a report to standard output that lists the modules imported by the
      script and their paths, as well as modules that are missing or seem to be
      missing.

   .. method:: run_script(pathname)

      Analyze the contents of the *pathname* file, which must contain Python
      code.

   .. attribute:: modules

      A dictionary mapping module names to modules. See
      :ref:`modulefinder-example`.


.. _modulefinder-example:

Example usage of :class:`ModuleFinder`
--------------------------------------

The script that is going to get analyzed later on (bacon.py)::

   import re, itertools

   try:
       import baconhameggs
   except ImportError:
       pass

   try:
       import guido.python.ham
   except ImportError:
       pass


The script that will output the report of bacon.py::

   from modulefinder import ModuleFinder

   finder = ModuleFinder()
   finder.run_script('bacon.py')

   print 'Loaded modules:'
   for name, mod in finder.modules.iteritems():
       print '%s: ' % name,
       print ','.join(mod.globalnames.keys()[:3])

   print '-'*50
   print 'Modules not imported:'
   print '\n'.join(finder.badmodules.iterkeys())

Sample output (may vary depending on the architecture)::

    Loaded modules:
    _types:
    copy_reg:  _inverted_registry,_slotnames,__all__
    sre_compile:  isstring,_sre,_optimize_unicode
    _sre:
    sre_constants:  REPEAT_ONE,makedict,AT_END_LINE
    sys:
    re:  __module__,finditer,_expand
    itertools:
    __main__:  re,itertools,baconhameggs
    sre_parse:  __getslice__,_PATTERNENDERS,SRE_FLAG_UNICODE
    array:
    types:  __module__,IntType,TypeType
    ---------------------------------------------------
    Modules not imported:
    guido.python.ham
    baconhameggs
