:mod:`tabnanny` --- Detection of ambiguous indentation
|
|
======================================================
|
|
|
|
.. module:: tabnanny
|
|
:synopsis: Tool for detecting white space related problems in Python source files in a
|
|
directory tree.
|
|
.. moduleauthor:: Tim Peters <tim_one@users.sourceforge.net>
|
|
.. sectionauthor:: Peter Funk <pf@artcom-gmbh.de>
|
|
|
|
.. rudimentary documentation based on module comments
|
|
|
|
For the time being this module is intended to be called as a script. However it
|
|
is possible to import it into an IDE and use the function :func:`check`
|
|
described below.
|
|
|
|
.. note::
|
|
|
|
The API provided by this module is likely to change in future releases; such
|
|
changes may not be backward compatible.
|
|
|
|
|
|
.. function:: check(file_or_dir)
|
|
|
|
If *file_or_dir* is a directory and not a symbolic link, then recursively
|
|
descend the directory tree named by *file_or_dir*, checking all :file:`.py`
|
|
files along the way. If *file_or_dir* is an ordinary Python source file, it
|
|
is checked for whitespace related problems. The diagnostic messages are
|
|
written to standard output using the :func:`print` function.
|
|
|
|
|
|
.. data:: verbose
|
|
|
|
Flag indicating whether to print verbose messages. This is incremented by the
|
|
``-v`` option if called as a script.
|
|
|
|
|
|
.. data:: filename_only
|
|
|
|
Flag indicating whether to print only the filenames of files containing
|
|
whitespace related problems. This is set to true by the ``-q`` option if called
|
|
as a script.
|
|
|
|
|
|
.. exception:: NannyNag
|
|
|
|
Raised by :func:`tokeneater` if detecting an ambiguous indent. Captured and
|
|
handled in :func:`check`.
|
|
|
|
|
|
.. function:: tokeneater(type, token, start, end, line)
|
|
|
|
This function is used by :func:`check` as a callback parameter to the function
|
|
:func:`tokenize.tokenize`.
