|
||
|
|
:synopsis: Find modules used by a script.
|
||
|
|
|
||
|
|
|
||
|
|
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.
