:mod:`modulefinder` --- Find modules used by a script
=====================================================
.. sectionauthor:: A.M. Kuchling <amk@amk.ca>
.. module:: modulefinder
:synopsis: Find modules used by a script.
.. versionadded:: 2.3
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:: ModuleFinder.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:: ModuleFinder.run_script(pathname)
Analyze the contents of the *pathname* file, which must contain Python code.
