40 | ## Get the list of codepoints for the type. | |
41 | ## Called from swash_init (see utf8.c) or SWASHNEW itself. | |
42 | ## | |
43 | ## Callers of swash_init: | |
44 | ## op.c:pmtrans -- for tr/// and y/// | |
45 | ## regexec.c:regclass_swash -- for /[]/, \p, and \P | |
46 | ## utf8.c:is_utf8_common -- for common Unicode properties | |
47 | ## utf8.c:to_utf8_case -- for lc, uc, ucfirst, etc. and //i | |
48 | ## | |
49 | ## Given a $type, our goal is to fill $list with the set of codepoint | |
50 | ## ranges. If $type is false, $list passed is used. | |
51 | ## | |
52 | ## $minbits: | |
53 | ## For binary properties, $minbits must be 1. | |
54 | ## For character mappings (case and transliteration), $minbits must | |
55 | ## be a number except 1. | |
56 | ## | |
57 | ## $list (or that filled according to $type): | |
58 | ## Refer to perlunicode.pod, "User-Defined Character Properties." | |
59 | ## | |
60 | ## For binary properties, only characters with the property value | |
61 | ## of True should be listed. The 3rd column, if any, will be ignored | |
62 | ## | |
63 | ## $none is undocumented, so I'm (khw) trying to do some documentation | |
64 | ## of it now. It appears to be if there is a mapping in an input file | |
65 | ## that maps to 'XXXX', then that is replaced by $none+1, expressed in | |
66 | ## hexadecimal. The only place I found it possibly used was in | |
67 | ## S_pmtrans in op.c. | |
68 | ## | |
69 | ## To make the parsing of $type clear, this code takes the a rather | |
70 | ## unorthodox approach of last'ing out of the block once we have the | |
71 | ## info we need. Were this to be a subroutine, the 'last' would just | |
72 | ## be a 'return'. | |
