|
|
|
66
|
|
|
67 Implementing a general data structure that maps from arbitrary
|
|
|
68 ranges of numbers to values is tricky to do efficiently. As it
|
|
|
69 happens, it should suffice (and is usually more convenient, anyway)
|
|
|
70 when dealing with characters to restrict the sorts of ranges that
|
|
|
71 can be assigned values, as follows:
|
|
|
72
|
|
|
73 1) All characters.
|
|
|
74 2) All characters in a charset.
|
|
|
75 3) All characters in a particular row of a charset, where a "row"
|
|
|
76 means all characters with the same first byte.
|
|
|
77 4) A particular character in a charset.
|
|
|
78
|
|
|
79 We use char tables to generalize the 256-element vectors now
|
|
|
80 littering the Emacs code.
|
|
|
81
|
|
|
82 Possible uses (all should be converted at some point):
|
|
|
83
|
|
|
84 1) category tables
|
|
|
85 2) syntax tables
|
|
|
86 3) display tables
|
|
|
87 4) case tables
|
|
|
88 5) keyboard-translate-table?
|
|
|
89
|
|
|
90 We provide an
|
|
|
91 abstract type to generalize the Emacs vectors and Mule
|
|
|
92 vectors-of-vectors goo.

|
|
530 A char table is a table that maps characters (or ranges of characters)
|
|
|
531 to values. Char tables are specialized for characters, only allowing
|
|
|
532 particular sorts of ranges to be assigned values. Although this
|
|
|
533 loses in generality, it makes for extremely fast (constant-time)
|
|
|
534 lookups, and thus is feasible for applications that do an extremely
|
|
|
535 large number of lookups (e.g. scanning a buffer for a character in
|
|
|
536 a particular syntax, where a lookup in the syntax table must occur
|
|
|
537 once per character).
|
|
|
538
|
|
|
539 When Mule support exists, the types of ranges that can be assigned
|
|
|
540 values are
|
|
|
541
|
|
|
542 -- all characters
|
|
|
543 -- an entire charset
|
|
|
544 -- a single row in a two-octet charset
|
|
|
545 -- a single character
|
|
|
546
|
|
|
547 When Mule support is not present, the types of ranges that can be
|
|
|
548 assigned values are
|
|
|
549
|
|
|
550 -- all characters
|
|
|
551 -- a single character
|
|
|
552
|
|
|
553 To create a char table, use `make-char-table'.
|
|
|
554 To modify a char table, use `put-char-table' or `remove-char-table'.
|
|
|
555 To retrieve the value for a particular character, use `get-char-table'.
|
|
826
|
556 See also `map-char-table', `reset-char-table', `copy-char-table',
|
|
800
|
557 `char-table-p', `valid-char-table-type-p', `char-table-type-list',
|
|
|
558 `valid-char-table-value-p', and `check-char-table-value'.
|
|
|
559
|
|
|
560 Each char table type is used for a different purpose and allows different
|
|
|
561 sorts of values. The different char table types are
|
|
|
562
|
|
|
563 `category'
|
|
|
564 Used for category tables, which specify the regexp categories
|
|
|
565 that a character is in. The valid values are nil or a
|
|
|
566 bit vector of 95 elements. Higher-level Lisp functions are
|
|
|
567 provided for working with category tables. Currently categories
|
|
|
568 and category tables only exist when Mule support is present.
|
|
|
569 `char'
|
|
|
570 A generalized char table, for mapping from one character to
|
|
|
571 another. Used for case tables, syntax matching tables,
|
|
|
572 `keyboard-translate-table', etc. The valid values are characters.
|
|
|
573 `generic'
|
|
|
574 An even more generalized char table, for mapping from a
|
|
|
575 character to anything.
|
|
|
576 `display'
|
|
|
577 Used for display tables, which specify how a particular character
|
|
|
578 is to appear when displayed. #### Not yet implemented.
|
|
|
579 `syntax'
|
|
|
580 Used for syntax tables, which specify the syntax of a particular
|
|
|
581 character. Higher-level Lisp functions are provided for
|
|
|
582 working with syntax tables. The valid values are integers.

|
1583 A category table is a type of char table used for keeping track of
|
|
|
1584 categories. Categories are used for classifying characters for use
|
|
|
1585 in regexps -- you can refer to a category rather than having to use
|
|
|
1586 a complicated [] expression (and category lookups are significantly
|
|
|
1587 faster).
|
|
|
1588
|
|
|
1589 There are 95 different categories available, one for each printable
|
|
|
1590 character (including space) in the ASCII charset. Each category
|
|
|
1591 is designated by one such character, called a "category designator".
|
|
|
1592 They are specified in a regexp using the syntax "\\cX", where X is
|
|
|
1593 a category designator.
|
|
|
1594
|
|
|
1595 A category table specifies, for each character, the categories that
|
|
|
1596 the character is in. Note that a character can be in more than one
|
|
|
1597 category. More specifically, a category table maps from a character
|
|
|
1598 to either the value nil (meaning the character is in no categories)
|
|
|
1599 or a 95-element bit vector, specifying for each of the 95 categories
|
|
|
1600 whether the character is in that category.
|
|
|
1601
|
|
|
1602 Special Lisp functions are provided that abstract this, so you do not
|
|

1603 have to directly manipulate bit vectors.
