57 /* A char table maps from ranges of characters to values.
|
|
|
58
|
|
|
59 Implementing a general data structure that maps from arbitrary
|
|
|
60 ranges of numbers to values is tricky to do efficiently. As it
|
|
183
|
61 happens, it should suffice (and is usually more convenient, anyway)
|
|
|
62 when dealing with characters to restrict the sorts of ranges that
|
|
|
63 can be assigned values, as follows:
|
|
70
|
64
|
|
|
65 1) All characters.
|
|
|
66 2) All characters in a charset.
|
|
|
67 3) All characters in a particular row of a charset, where a "row"
|
|
|
68 means all characters with the same first byte.
|
|
|
69 4) A particular character in a charset.
|
|
|
70
|
|
|
71 We use char tables to generalize the 256-element vectors now
|
|
|
72 littering the Emacs code.
|
|
|
73
|
|
|
74 Possible uses (all should be converted at some point):
|
|
|
75
|
|
|
76 1) category tables
|
|
|
77 2) syntax tables
|
|
|
78 3) display tables
|
|
|
79 4) case tables
|
|
|
80 5) keyboard-translate-table?
|
|
|
81
|
|
|
82 We do the very non-Stallman-esque thing of actually providing an
|
|
|
83 abstract type to generalize the Emacs vectors and Mule
|
|
|
84 vectors-of-vectors goo.

437 A char table is a table that maps characters (or ranges of characters)
|
|
|
438 to values. Char tables are specialized for characters, only allowing
|
|
|
439 particular sorts of ranges to be assigned values. Although this
|
|
|
440 loses in generality, it makes for extremely fast (constant-time)
|
|
|
441 lookups, and thus is feasible for applications that do an extremely
|
|
|
442 large number of lookups (e.g. scanning a buffer for a character in
|
|
|
443 a particular syntax, where a lookup in the syntax table must occur
|
|
|
444 once per character).
|
|
|
445
|
|
|
446 When Mule support exists, the types of ranges that can be assigned
|
|
|
447 values are
|
|
|
448
|
|
|
449 -- all characters
|
|
|
450 -- an entire charset
|
|
|
451 -- a single row in a two-octet charset
|
|
|
452 -- a single character
|
|
|
453
|
|
|
454 When Mule support is not present, the types of ranges that can be
|
|
|
455 assigned values are
|
|
|
456
|
|
|
457 -- all characters
|
|
|
458 -- a single character
|
|
|
459
|
|
|
460 To create a char table, use `make-char-table'. To modify a char
|
|
|
461 table, use `put-char-table' or `remove-char-table'. To retrieve the
|
|
|
462 value for a particular character, use `get-char-table'. See also
|
|
|
463 `map-char-table', `clear-char-table', `copy-char-table',

506 is to appear when displayed. #### Not yet implemented.

507 `syntax'

1552 A category table is a type of char table used for keeping track of
|
|
|
1553 categories. Categories are used for classifying characters for use
|
|
|
1554 in regexps -- you can refer to a category rather than having to use
|
|
|
1555 a complicated [] expression (and category lookups are significantly
|
|
|
1556 faster).
|
|
|
1557
|
|
|
1558 There are 95 different categories available, one for each printable
|
|
|
1559 character (including space) in the ASCII charset. Each category
|
|
185
|
1560 is designated by one such character, called a "category designator".
|
|
|
1561 They are specified in a regexp using the syntax "\\cX", where X is
|
|
104
|
1562 a category designator.
|
|
70
|
1563
|
|
|
1564 A category table specifies, for each character, the categories that
|
|
|
1565 the character is in. Note that a character can be in more than one
|
|
|
1566 category. More specifically, a category table maps from a character
|
|
|
1567 to either the value nil (meaning the character is in no categories)
|
|
|
1568 or a 95-element bit vector, specifying for each of the 95 categories
|
|
|
1569 whether the character is in that category.
|
|
|
1570
|
|
|
1571 Special Lisp functions are provided that abstract this, so you do not
|
|
|
1572 have to directly manipulate bit vectors.
