: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 **Source code:** :source:`Lib/tabnanny.py` -------------- 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 print statement. .. 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`. ..
