66 ## Unicode::UCD::prop_invlist
67 ## Unicode::UCD::prop_invmap
68 ##
69 ## Given a $type, our goal is to fill $list with the set of codepoint
70 ## ranges. If $type is false, $list passed is used.
71 ##
72 ## $minbits:
73 ## For binary properties, $minbits must be 1.
74 ## For character mappings (case and transliteration), $minbits must
75 ## be a number except 1.
76 ##
77 ## $list (or that filled according to $type):
78 ## Refer to perlunicode.pod, "User-Defined Character Properties."
79 ##
80 ## For binary properties, only characters with the property value
81 ## of True should be listed. The 3rd column, if any, will be ignored
82 ##
83 ## $none is undocumented, so I'm (khw) trying to do some documentation
84 ## of it now. It appears to be if there is a mapping in an input file
85 ## that maps to 'XXXX', then that is replaced by $none+1, expressed in
86 ## hexadecimal. It is used somehow in tr///.
87 ##
88 ## To make the parsing of $type clear, this code takes the a rather
89 ## unorthodox approach of last'ing out of the block once we have the
90 ## info we need. Were this to be a subroutine, the 'last' would just
91 ## be a 'return'.
