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. s0.1.3sjoe@bitworking.orgs MIT Licensetc CsÂ|idƒ}tg}|dD]@}|tg}|iddƒD]}||iƒqD~ƒq!~ƒ}|diƒ}|djo d}n|idƒ\}} |iƒ| iƒ|fS(sUParses a mime-type into its component parts.

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. iÿÿÿÿiRcSs||S(((txty((sd/Users/riccardo/git/gcloud/packages/gcutil-1.7.1/lib/google_api_python_client/apiclient/mimeparse.pytdsRiidi (Rtreducet iteritemsRR(R t parsed_rangest best_fitnesst best_fit_qt target_typettarget_subtypet target_paramsRRRt type_matcht subtype_matchR tkeytvaluet param_matchestfitness((sd/Users/riccardo/git/gcloud/packages/gcutil-1.7.1/lib/google_api_python_client/apiclient/mimeparse.pytfitness_and_quality_parsedOs,       #;  cCst||ƒdS(s–Find 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-iiiÿÿÿÿiR(t _filter_blankRRtappendR+tsort( t supportedtheadert split_headerR R/t parsed_headertweighted_matchestposR ((sd/Users/riccardo/git/gcloud/packages/gcutil-1.7.1/lib/google_api_python_client/apiclient/mimeparse.pyt best_matchŽs'  ccs+x$|D]}|iƒo |VqqWdS(N(R(tiR((sd/Users/riccardo/git/gcloud/packages/gcutil-1.7.1/lib/google_api_python_client/apiclient/mimeparse.pyR1©s N( t__doc__t __version__t __email__t __license__t __credits__RRR+R,R0R:R1(((sd/Users/riccardo/git/gcloud/packages/gcutil-1.7.1/lib/google_api_python_client/apiclient/mimeparse.pyts   "
