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 Licensec ~|jd}t|ddDcgc]9}t|jddDcgc]}|jc};c}}}|dj}|dk(rd}|jd\}}|j|j|fScc}wcc}}w) 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)rangerrrs rparse_media_ranger;sh.e4T7F 6c{VC[!   !   !s '6 ""c d}d}t|\}}}|D]\}}} ||k(xs |dk(xs|dk(} ||k(xs |dk(xs|dk(} | s0| s3td|jD cgc]\} } | dk7r| | vr | | | k(rdc} } d}||k(xrdxsd}|||k(xrdxsdz }||z }||kDs|}| d}|t|fScc} } w) 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. rr c ||zSN)xys rz,fitness_and_quality_parsed..is QUr rrd )rritemsr)r parsed_ranges best_fitness best_fit_q target_typetarget_subtype target_paramsrrr type_match subtype_matchkeyvalue param_matchesfitnesss rfitness_and_quality_parsedr8Vs.LJ3DY3O0[.-#0)w[(MDCKM;#;M ~ % PC P>S;P  -"")6(;(;(=$eczcVm8L M{*38qG >19r>Q >G } $G%& #C[ )), z* **s#Cc t||dS)aFind the best match for a mime-type amongst parsed media-ranges.

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<rrr"r) _filter_blankr rappendr8sort) supportedheader split_headerr> parsed_headerweighted_matchesposrs r best_matchrKs!c!23L3?@a&q)@M@ C  ' = A3 R  q   B  "1 % A*:2*>q*A GRGAsB c#DK|D]}|js|ywr$)r)irs rrBrBs#  779Gs  N)__doc__ __future__r functoolsr __version__ __author__ __email__ __license__ __credits__rrr8r:r?rKrBr%r rrVsQ &'    30#6"+J C 4 H8r
