: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 .. sectionauthor:: Peter Funk .. 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:`process_tokens` if detecting an ambiguous indent. Captured and handled in :func:`check`. .. function:: process_tokens(tokens) This function is used by :func:`check` to process tokens generated by the :mod:`tokenize` module. .. XXX document errprint, format_witnesses, Whitespace, check_equal, indents, reset_globals .. seealso:: Module :mod:`tokenize` Lexical scanner for Python source code.
