It accepts a readline-like method which is called repeatedly to get the next line of input (or "" for EOF). It generates 5-tuples with these members: the token type (see token.py) the token (a string) the starting (row, column) indices of the token (a 2-tuple of ints) the ending (row, column) indices of the token (a 2-tuple of ints) the original line (string) It is designed to match the working of the Python tokenizer exactly, except that it produces COMMENT tokens for comments and gives type OP for all operators Older entry points tokenize_loop(readline, tokeneater) tokenize(readline, tokeneater=printtoken) are the same, except instead of generating tokens, tokeneater is a callback function to which the 5 fields described above are passed as 5 arguments, each time a new token is found.s Ka-Ping Yee <ping@lfw.org>s@ GvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip Montanaroi����N( t BOM_UTF8t lookup( t *i ( t tokeni t _t tokenizet generate_tokenst untokenizec G s d d j | � d S( Nt (t |t )( t join( t choices( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt group0 s c G s t | � d S( NR ( R ( R ( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt any1 s c G s t | � d S( Nt ?( R ( R ( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt maybe2 s s [ \f\t]*s #[^\r\n]*s \\\r?\ns [a-zA-Z_]\w*s 0[bB][01]*s 0[xX][\da-fA-F]*[lL]?s 0[oO]?[0-7]*[lL]?s [1-9]\d*[lL]?s [eE][-+]?\d+s \d+\.\d*s \.\d+s \d+s \d+[jJ]s [jJ]s [^'\\]*(?:\\.[^'\\]*)*'s [^"\\]*(?:\\.[^"\\]*)*"s% [^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''s% [^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""s [ubUB]?[rR]?'''s [ubUB]?[rR]?"""s& [uU]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*'s& [uU]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*"s \*\*=?s >>=?s <<=?s <>s !=s //=?s ->s [+\-*/%&|^=<>]=?t ~s [][(){}]s \r?\ns [:;.,`@]s' [uUbB]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*t 's' [uUbB]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*t "s '''s """s r'''s r"""s u'''s u"""s b'''s b"""s ur'''s ur"""s br'''s br"""s R'''s R"""s U'''s U"""s B'''s B"""s uR'''s uR"""s Ur'''s Ur"""s UR'''s UR"""s bR'''s bR"""s Br'''s Br"""s BR'''s BR"""t rt Rt ut Ut bt Bs r's r"s R's R"s u's u"s U's U"s b's b"s B's B"s ur's ur"s Ur's Ur"s uR's uR"s UR's UR"s br's br"s Br's Br"s bR's bR"s BR's BR"i t TokenErrorc B s e Z RS( ( t __name__t __module__( ( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyR � s t StopTokenizingc B s e Z RS( ( R R ( ( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyR � s c C sA | \ } } | \ } } d | | | | t | t | � f GHd S( Ns %d,%d-%d,%d: %s %s( t tok_namet repr( t typeR t startt endt linet srowt scolt erowt ecol( ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt printtoken� s c C s) y t | | � Wn t k r$ n Xd S( s: The tokenize() function accepts two parameters: one representing the input stream, and one providing an output mechanism for tokenize(). The first parameter, readline, must be a callable object which provides the same interface as the readline() method of built-in file objects. Each call to the function should return one line of input as a string. The second parameter, tokeneater, must also be a callable object. It is called once for each token, with five arguments, corresponding to the tuples generated by generate_tokens().

It requires one argment, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised. If the encoding cookie is an invalid charset, raise a SyntaxError. Note that if a utf-8 bom is found, 'utf-8-sig' is returned. If no encoding is specified, then the default of 'utf-8' will be returned. s utf-8c s' y � � SWn t k r" t � SXd S( N( t StopIterationt bytes( ( R* ( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt read_or_stop s c s� y | j d � } Wn t k r' d SXt j | � } | sA d St | d � } y t | � } Wn! t k r� t d | � � n X� r� | j d k r� t d � � n | d 7} n | S( Nt asciii s unknown encoding: s utf-8s encoding problem: utf-8s -sig( t decodet UnicodeDecodeErrort Nonet cookie_ret findallRT R t LookupErrort SyntaxErrort name( R# t line_stringt matchest encodingt codec( t bom_found( s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt find_cookie s" i s utf-8-sigN( RA R[ RQ R RD ( R* Rc t defaultRW Rf t firstt second( ( Re R* s. /usr/lib64/python2.7/lib2to3/pgen2/tokenize.pyt detect_encoding� s, c C s t � } | j | � S( s� Transform tokens back into Python source code.
