There are as many interpolable sub-spaces as there are combinations of discrete axis values. E.g. with axes: - italic (discrete) Upright or Italic - style (discrete) Sans or Serif - weight (continuous) 100 to 900 There are 4 sub-spaces in which the Weight axis should interpolate: (Upright, Sans), (Upright, Serif), (Italic, Sans) and (Italic, Serif). The sub-designspaces still include the full axis definitions and STAT data, but the rules, sources, variable fonts, instances are trimmed down to only keep what falls within the interpolable sub-space. Args: - ``makeNames``: Whether to compute the instance family and style names using the STAT data. - ``expandLocations``: Whether to turn all locations into "full" locations, including implicit default axis values where missing. - ``makeInstanceFilename``: Callable to synthesize an instance filename when makeNames=True, for instances that don't specify an instance name in the designspace. This part of the name generation can be overridden because it's not specified by the STAT table. .. versionadded:: 5.0 valuescSsg|] }|jqSr')r/).0axisr'r'r( gsz%splitInterpolable..cSsi|]\}}|j|qSr')name)r0Z discreteAxisvaluer'r'r( isz%splitInterpolable..TkeepVFsr,r-r.N)axeshasattrr r appendr rminimummaximumdefaultr3 itertoolsproductzip_extractSubSpace) rr,r-r.Z discreteAxesZinterpolableUserRegionr1ZvalueCombinationsr/ZdiscreteUserLocationsubDocr'r'r(splitInterpolable5s4"      rCFz)Iterator[Tuple[str, DesignSpaceDocument]]c csJ|D]<}t||}t||d|||d}|j|j|_|j|fVqdS)a$Convert each variable font listed in this document into a standalone designspace.
