It can handle matching mime-types against a list of media-ranges. See section 14.1 of the HTTP specification [RFC 2616] for a complete explanation. http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1 Contents: - parse_mime_type(): Parses a mime-type into its component parts. - parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q' quality parameter. - quality(): Determines the quality ('q') of a mime-type when compared against a list of media-ranges. - quality_parsed(): Just like quality() except the second parameter must be pre-parsed. - best_match(): Choose the mime-type with the highest quality ('q') from a list of candidates. )absolute_import)reducez0.1.3z Joe Gregoriozjoe@bitworking.orgz MIT LicensecCs\|d}tdd|ddD}|d}|dkrd}|d \}}|||fS) aRParses a mime-type into its component parts. Carves up a mime-type and returns a tuple of the (type, subtype, params) where 'params' is a dictionary of all the parameters for the media range.

Carves up a media range and returns a tuple of the (type, subtype, params) where 'params' is a dictionary of all the parameters for the media range. For example, the media range 'application/*;q=0.5' would get parsed into: ('application', '*', {'q', '0.5'}) In addition this function also guarantees that there is a value for 'q' in the params dictionary, filling it in with a proper default if necessary. qrr1)rfloat)rangerrrrrr parse_media_range;s  r!c sd}d}t|\}}}|D]R\}}||kp|dkp|dk} ||kp)|dkp)|dk} | r_| r_tddfdd|Dd} ||krEdpFd} | ||krNd pOd7} | | 7} | |kr_| }d }q |t|fS) aFind the best match for a mime-type amongst parsed media-ranges. Find the best match for a given mime-type against a list of media_ranges that have already been parsed by parse_media_range(). Returns a tuple of the fitness value and the value of the 'q' quality parameter of the best match, or (-1, 0) if no match was found. Just as for quality_parsed(), 'parsed_ranges' must be a list of parsed media ranges. rrcSs||SNr)xyrrr isz,fitness_and_quality_parsed..cs0g|]\}}|dkr|vr||krdqS)rrr)r keyvaluerrr r js z.fitness_and_quality_parsed..d r)r!ritemsr) r parsed_ranges best_fitness best_fit_q target_typetarget_subtype target_paramsrr type_match subtype_match param_matchesfitnessrr)r fitness_and_quality_parsedVs.    r7cCst||dS)aFind the best match for a mime-type amongst parsed media-ranges. Find the best match for a given mime-type against a list of media_ranges that have already been parsed by parse_media_range(). Returns the 'q' quality parameter of the best match, 0 if no match was found. This function bahaves the same as quality() except that 'parsed_ranges' must be a list of parsed media ranges. r)r7)rr-rrr quality_parsed{s r8cCsdd|dD}t||S)aKReturn the quality ('q') of a mime-type against a list of media-ranges. Returns the quality 'q' of a mime-type when compared against the media-ranges in ranges. For example: >>> quality('text/html','text/*;q=0.3, text/html;q=0.7, text/html;level=1, text/html;level=2;q=0.4, */*;q=0.5') 0.7 cSg|]}t|qSrr!r rrrr r r zquality..,)rr8)rrangesr-rrr qualitys r?cCstt|d}dd|D}g}d}|D]}|t||||f|d7}q||dddr8|ddp9dS) aYReturn mime-type with the highest quality ('q') from list of candidates. Takes a list of supported mime-types and finds the best match for all the media-ranges listed in header. The value of header must be a string that conforms to the format of the HTTP Accept: header. The value of 'supported' is a list of mime-types. The list of supported mime-types should be sorted in order of increasing desirability, in case of a situation where there is a tie. >>> best_match(['application/xbel+xml', 'text/xml'], 'text/*;q=0.5,*/*; q=0.1') 'text/xml' r=cSr9rr:r;rrr r r zbest_match..rrr"r) _filter_blankrappendr7sort) supportedheader split_header parsed_headerweighted_matchesposrrrr best_matchs  rJccs|D] }|r |VqdSr#r)ir rrr rAs rAN)__doc__ __future__r functoolsr __version__ __author__ __email__ __license__ __credits__rr!r7r8r?rJrArrrr s  %
