1:mod:`tabnanny` --- Detection of ambiguous indentation 2====================================================== 3 4.. module:: tabnanny 5 :synopsis: Tool for detecting white space related problems in Python 6 source files in a directory tree. 7 8.. moduleauthor:: Tim Peters <tim_one@users.sourceforge.net> 9.. sectionauthor:: Peter Funk <pf@artcom-gmbh.de> 10 11.. rudimentary documentation based on module comments 12 13**Source code:** :source:`Lib/tabnanny.py` 14 15-------------- 16 17For the time being this module is intended to be called as a script. However it 18is possible to import it into an IDE and use the function :func:`check` 19described below. 20 21.. note:: 22 23 The API provided by this module is likely to change in future releases; such 24 changes may not be backward compatible. 25 26 27.. function:: check(file_or_dir) 28 29 If *file_or_dir* is a directory and not a symbolic link, then recursively 30 descend the directory tree named by *file_or_dir*, checking all :file:`.py` 31 files along the way. If *file_or_dir* is an ordinary Python source file, it 32 is checked for whitespace related problems. The diagnostic messages are 33 written to standard output using the :func:`print` function. 34 35 36.. data:: verbose 37 38 Flag indicating whether to print verbose messages. This is incremented by the 39 ``-v`` option if called as a script. 40 41 42.. data:: filename_only 43 44 Flag indicating whether to print only the filenames of files containing 45 whitespace related problems. This is set to true by the ``-q`` option if called 46 as a script. 47 48 49.. exception:: NannyNag 50 51 Raised by :func:`process_tokens` if detecting an ambiguous indent. Captured and 52 handled in :func:`check`. 53 54 55.. function:: process_tokens(tokens) 56 57 This function is used by :func:`check` to process tokens generated by the 58 :mod:`tokenize` module. 59 60.. XXX document errprint, format_witnesses, Whitespace, check_equal, indents, 61 reset_globals 62 63 64.. seealso:: 65 66 Module :mod:`tokenize` 67 Lexical scanner for Python source code. 68
