31 /* The four tables in a case table are downcase, upcase, canon, and eqv.
|
|
32 Each is a char-table. Their workings are rather non-obvious.
|
|
33
|
|
34 (1) `downcase' is the only obvious table: Map a character to its
|
|
35 lowercase equivalent.
|
771
|
36
|
826
|
37 (2) `upcase' does *NOT* map a character to its uppercase equivalent,
|
|
38 despite its name. Rather, it maps lowercase characters to their
|
|
39 uppercase equivalent, and uppercase characters to *ANYTHING BUT* their
|
|
40 uppercase equivalent (currently, their lowercase equivalent), and
|
|
41 characters without case to themselves. It is used to determine if a
|
|
42 character "has no case" (no uppercase or lowercase mapping). #### This
|
|
43 is way bogus. Just use the obvious implementation of uppercase mapping
|
|
44 and of NOCASE_P.
|
446
|
45
|
826
|
46 (3) `canon' maps each character to a "canonical" lowercase, such that if
|
|
47 two different uppercase characters map to the same lowercase character,
|
|
48 or vice versa, both characters will have the same entry in the canon
|
|
49 table.
|
446
|
50
|
826
|
51 (4) `equiv' lists the "equivalence classes" defined by `canon'. Imagine
|
|
52 that all characters are divided into groups having the same `canon'
|
|
53 entry; these groups are called "equivalence classes" and `equiv' lists
|
|
54 them by linking the characters in each equivalence class together in a
|
|
55 circular list.
|
|
56
|
|
57 `canon' is used when doing case-insensitive comparisons. `equiv' is
|
|
58 used in the Boyer-Moore search code.
