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.u Ka-Ping Yee <ping@lfw.org>u@ GvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip Montanaroi N( u BOM_UTF8u lookup( u *i ( u tokenc C s& g | ] } | d d k r | � q S( i u _( ( u .0u x( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu <listcomp>% s u <listcomp>u tokenizeu generate_tokensu untokenizec G s d d j | � d S( Nu (u |u )( u join( u choices( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu group0 s u groupc G s t | � d S( Nu *( u group( u choices( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu any1 s u anyc G s t | � d S( Nu ?( u group( u choices( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu maybe2 s u maybeu [ \f\t]*u #[^\r\n]*u \\\r?\nu [a-zA-Z_]\w*u 0[bB][01]*u 0[xX][\da-fA-F]*[lL]?u 0[oO]?[0-7]*[lL]?u [1-9]\d*[lL]?u [eE][-+]?\d+u \d+\.\d*u \.\d+u \d+u \d+[jJ]u [jJ]u [^'\\]*(?:\\.[^'\\]*)*'u [^"\\]*(?:\\.[^"\\]*)*"u% [^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''u% [^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""u [ubUB]?[rR]?'''u [ubUB]?[rR]?"""u& [uU]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*'u& [uU]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*"u \*\*=?u >>=?u <<=?u <>u !=u //=?u ->u [+\-*/%&|^=<>]=?u ~u [][(){}]u \r?\nu [:;.,`@]u' [uUbB]?[rR]?'[^\n'\\]*(?:\\.[^\n'\\]*)*u 'u' [uUbB]?[rR]?"[^\n"\\]*(?:\\.[^\n"\\]*)*u "u '''u """u r'''u r"""u u'''u u"""u b'''u b"""u ur'''u ur"""u br'''u br"""u R'''u R"""u U'''u U"""u B'''u B"""u uR'''u uR"""u Ur'''u Ur"""u UR'''u UR"""u bR'''u bR"""u Br'''u Br"""u BR'''u BR"""u ru Ru uu Uu bu Bu r'u r"u R'u R"u u'u u"u U'u U"u b'u b"u B'u B"u ur'u ur"u Ur'u Ur"u uR'u uR"u UR'u UR"u br'u br"u Br'u Br"u bR'u bR"u BR'u BR"i c B s | Ee Z d Z d S( u TokenErrorN( u __name__u __module__u __qualname__( u __locals__( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu TokenError� s u TokenErrorc B s | Ee Z d Z d S( u StopTokenizingN( u __name__u __module__u __qualname__( u __locals__( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu StopTokenizing� s u StopTokenizingc C sF | \ } } | \ } } t d | | | | t | t | � f � d S( Nu %d,%d-%d,%d: %s %s( u printu tok_nameu repr( u typeu tokenu xxx_todo_changemeu xxx_todo_changeme1u lineu srowu scolu erowu ecol( ( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu printtoken� s u printtokenc C s* y t | | � Wn t k r% Yn Xd S( u: The tokenize() function accepts two parameters: one representing the input stream, and one providing an output mechanism for tokenize().

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 requires one argument, 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. u utf-8c s+ y � � SWn t k r& t � SYn Xd S( N( u StopIterationu bytes( ( u readline( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu read_or_stop s u% detect_encoding.<locals>.read_or_stopc s� y | j d � } Wn t k r+ d SYn Xt j | � } | sE d St | j d � � } y t | � } Wn" t k r� t d | � � Yn X� r� | j d k r� t d � � n | d 7} n | S( Nu asciii u unknown encoding: u utf-8u encoding problem: utf-8u -sig( u decodeu UnicodeDecodeErroru Noneu cookie_reu matchu _get_normal_nameu groupu lookupu LookupErroru SyntaxErroru name( u lineu line_stringu matchu encodingu codec( u bom_found( u; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu find_cookie s" u$ detect_encoding.<locals>.find_cookiei Nu utf-8-sigFT( u Falseu Noneu startswithu BOM_UTF8u Trueu blank_reu match( u readlineu encodingu defaultu read_or_stopu find_cookieu firstu second( ( u bom_foundu readlineu; /opt/alt/python33/lib64/python3.3/lib2to3/pgen2/tokenize.pyu detect_encoding� s0 u detect_encodingc C s t � } | j | � S( u� Transform tokens back into Python source code.
