It decodes the bytes according to PEP-0263 for determining source file encoding. It accepts a readline-like method which is called repeatedly to get the next line of input (or b"" 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. Additionally, all token lists start with an ENCODING token which tells you which encoding was used to decode the bytes stream. zKa-Ping Yee zpGvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip Montanaro, Raymond Hettinger, Trent Nelson, Michael Foord)open)lookupBOM_UTF8N) TextIOWrapper)*)EXACT_TOKEN_TYPESz&^[ \t\f]*#.*?coding[:=][ \t]*([-\w.]+)s^[ \t\f]*(?:[#\r\n]|$))tokenizegenerate_tokensdetect_encoding untokenize TokenInfoc"eZdZdZedZy)r cpd|jt|jfz}d|j|zS)Nz%d (%s)z8TokenInfo(type=%s, string=%r, start=%r, end=%r, line=%r))type)rtok_name_replace)selfannotated_types %/usr/local/lib/python3.12/tokenize.py__repr__zTokenInfo.__repr__0s9"dii$))1D%EEJ > 23 4c|jtk(r%|jtvrt|jS|jSN)rOPstringrrs r exact_typezTokenInfo.exact_type5s2 99?t{{.??$T[[1 199 rN)__name__ __module__ __qualname__rpropertyrrrr r /s4 rr ztype string start end linec0ddj|zdzS)N(|))joinchoicess rgroupr*<sC#((7"33c99rct|dzS)Nrr*r(s ranyr-=s%/C//rct|dzS)N?r,r(s rmayber0>sE7Oc11rz[ \f\t]*z #[^\r\n]*z\\\r?\nz\w+z0[xX](?:_?[0-9a-fA-F])+z0[bB](?:_?[01])+z0[oO](?:_?[0-7])+z(?:0(?:_?0)*|[1-9](?:_?[0-9])*)z[eE][-+]?[0-9](?:_?[0-9])*z)[0-9](?:_?[0-9])*\.(?:[0-9](?:_?[0-9])*)?z\.[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*[jJ]z[jJ]c  gd}dh}|D]q}tj|D]W}tj|Dcgc]}||jfc}D]"}|j dj |$Ys|Scc}w)N)brufbrfr) _itertools permutationsproductupperaddr')_valid_string_prefixesresultprefixtcr4s r_all_string_prefixesrCUs>TF(((0A ''!)D!Q1aggi.!)DE 2771:&F1) M*EsB cJtj|tjSr)recompileUNICODE)exprs r_compilerIds ::dBJJ ''rz[^'\\]*(?:\\.[^'\\]*)*'z[^"\\]*(?:\\.[^"\\]*)*"z%[^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''z%[^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""z'''z"""z'[^\n'\\]*(?:\\.[^\n'\\]*)*'z"[^\n"\\]*(?:\\.[^\n"\\]*)*"T)reversez\r?\nz'[^\n'\\]*(?:\\.[^\n'\\]*)*'z"[^\n"\\]*(?:\\.[^\n"\\]*)*"z \\\r?\n|\Zc eZdZy) TokenErrorNrrr r"rrrOrOrrOc eZdZy)StopTokenizingNrPr"rrrSrSrQrrSc0eZdZdZdZdZdZdZdZy) UntokenizercXg|_d|_d|_d|_d|_d|_y)Nrr8)tokensprev_rowprev_col prev_type prev_lineencodingrs r__init__zUntokenizer.__init__s,    rcL|\}}||jks||jk(r@||jkr1tdj|||j|j|j |||jz }|r|j j d|zyy)Nz+start ({},{}) precedes previous end ({},{}) )rYrZ ValueErrorformatadd_backslash_continuationrXappend)rstartrowcol col_offsets radd_whitespacezUntokenizer.add_whitespacesS  #"63;NJ$fS#t}}dmmLN N ''.4==(  KK  sZ/ 0 rcz|d}||jz }|dk(ry|jjdrdnd}|jjd}dj t j tjt|}|jj|d||zzd|_ y)zAdd backslash continuation characters if the row has increased without encountering a newline token.

It returns a bytes object, encoded using the ENCODING token, which is the first token sequence output by tokenize. Each element returned by the iterable must be a token sequence with at least two elements, a token number and token value. If only two tokens are passed, the resulting output is poor. The result is guaranteed to tokenize back to match the input so that the conversion is lossless and round-trips are assured. The guarantee applies only to the token type and token string as the spacing between tokens (column positions) may change. )rUr r]encode)rutouts rr r Hs: B -- !C {{jj% Jrc|ddjjdd}|dk(s|jdry|dvs|jdry |S) z(Imitates get_normal_name in tokenizer.c.N _-utf-8zutf-8-)zlatin-1 iso-8859-1z iso-latin-1)zlatin-1-z iso-8859-1-z iso-latin-1-r)lowerreplace startswith)orig_encencs r_get_normal_namer]sX 3B-    ' 'S 1C g~1 66 ~~AB Orcj jjdd}d}fd}fd}|}|jtr d|dd}d}|s|gfS||}|r||gfSt j |s||gfS|}|s||gfS||}|r|||gfS|||gfS#t$rdYwxYw) a The detect_encoding() function is used to detect the encoding that should be used to decode a Python source file. 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.

Each call to the function should return one line of input as bytes. Alternatively, readline can be a callable function terminating with StopIteration: readline = open(myfile, 'rb').__next__ # Example of alternate readline The generator produces 5-tuples with these members: the token type; the token string; a 2-tuple (srow, scol) of ints specifying the row and column where the token begins in the source; a 2-tuple (erow, ecol) of ints specifying the row and column where the token ends in the source; and the line on which the token was found. The line passed is the physical line. The first token sequence will always be an ENCODING token which tells you which encoding was used to decode the bytes stream. rNrr)rrr8T extra_tokens)r r9rrr r!_generate_tokens_from_c_tokenizer__next__)rr]consumedrl_gens rr r sm&)2Hh   hXs(; .perrors& ! rc|r|f|z|fz}d|zn|r|d|n d|ztjdy)Nz%s:%d:%d: error: %sz : error: z error: %srW)rexit)rrlocationargsrs rerrorzmain..errorsO ;)WJ6D (4/ 0  h8 9 ;( )  rzpython -m tokenize)progrr/z filename.pyz'the file to tokenize; defaults to stdin)destnargsmetavarhelpz-ez--exactexact store_truez(display token names using the exact type)ractionrrzTrz %d,%d-%d,%d:2015rWrz interrupted zunexpected error: %s)NN)argparseArgumentParser add_argument parse_argsrrlistr rrrstdinrrrrerprintrrIndentationErrorrrOrOSErrorKeyboardInterrupt Exception)rrparserrrr5rXr token_type token_rangeerrrucolumnrs @rmainrs $ $*> $ ?F Zs -FH iglGI    D" ==}}Hx.!hqzz23/.!H6 ""7F EJzz"-- (EKK%)),CDK  4ellD E /. 5xx{1Q' f chhqk8dF^44 5xx{ f chhqk8dF^44  c8  c  o %+, sg$E D= BE =EE H&.F H&+G H& G H&'G44H& H& H!!H&cd|vry|S)zTransform error messages from the C tokenizer into the Python tokenize The C tokenizer is more picky than the Python one, so we need to massage the error messages a bit for backwards compatibility. z)unterminated triple-quoted string literalzEOF in multi-line stringr")rs r_transform_msgr7s 3c9) Jrc#jK|tj||}ntj|||} |D]}tj|y#t$rR}t |tk7r|dt |j}t||j|jfdd}~wwxYww)zWTokenize a source reading Python code as unicode strings using the internal C tokenizerNr)r]r) _tokenize TokenizerIterr _makerrrrrOlinenooffset)sourcer]rrinfoers rrrAs  $ $V, G  $ $Vh\ Z>D//$' ' > 7k !
