55 /* A keymap contains four slots:
|
|
|
56
|
|
|
57 parents Ordered list of keymaps to search after
|
|
|
58 this one if no match is found.
|
|
|
59 Keymaps can thus be arranged in a hierarchy.
|
|
|
60
|
|
|
61 table A hash table, hashing keysyms to their bindings.
|
|
70
|
62 It will be one of the following:
|
|
|
63
|
|
|
64 -- a symbol, e.g. 'home
|
|
|
65 -- a character, representing something printable
|
|
|
66 (not ?\C-c meaning C-c, for instance)
|
|
|
67 -- an integer representing a modifier combination
|
|
0
|
68
|
|
|
69 inverse_table A hash table, hashing bindings to the list of keysyms
|
|
|
70 in this keymap which are bound to them. This is to make
|
|
|
71 the Fwhere_is_internal() function be fast. It needs to be
|
|
|
72 fast because we want to be able to call it in realtime to
|
|
|
73 update the keyboard-equivalents on the pulldown menus.
|
|
|
74 Values of the table are either atoms (keysyms)
|
|
|
75 or a dotted list of keysyms.
|
|
|
76
|
|
|
77 sub_maps_cache An alist; for each entry in this keymap whose binding is
|
|
|
78 a keymap (that is, Fkeymapp()) this alist associates that
|
|
|
79 keysym with that binding. This is used to optimize both
|
|
|
80 Fwhere_is_internal() and Faccessible_keymaps(). This slot
|
|
|
81 gets set to the symbol `t' every time a change is made to
|
|
|
82 this keymap, causing it to be recomputed when next needed.
|
|
|
83
|
|
|
84 prompt See `set-keymap-prompt'.
|
|
|
85
|
|
|
86 default_binding See `set-keymap-default-binding'.
|
|
|
87
|
|
|
88 Sequences of keys are stored in the obvious way: if the sequence of keys
|
|
|
89 "abc" was bound to some command `foo', the hierarchy would look like
|
|
|
90
|
|
|
91 keymap-1: associates "a" with keymap-2
|
|
|
92 keymap-2: associates "b" with keymap-3
|
|
|
93 keymap-3: associates "c" with foo
|
|
|
94
|
|
|
95 However, bucky bits ("modifiers" to the X-minded) are represented in the
|
|
|
96 keymap hierarchy as well. (This lets us use EQable objects as hash keys.)
|
|
|
97 Each combination of modifiers (e.g. control-hyper) gets its own submap
|
|
|
98 off of the main map. The hash key for a modifier combination is
|
|
70
|
99 an integer, computed by MAKE_MODIFIER_HASH_KEY().
|
|
0
|
100
|
|
|
101 If the key `C-a' was bound to some command, the hierarchy would look like
|
|
|
102
|
|
70
|
103 keymap-1: associates the integer MOD_CONTROL with keymap-2
|
|
0
|
104 keymap-2: associates "a" with the command
|
|
|
105
|
|
|
106 Similarly, if the key `C-H-a' was bound to some command, the hierarchy
|
|
|
107 would look like
|
|
|
108
|
|
70
|
109 keymap-1: associates the integer (MOD_CONTROL | MOD_HYPER)
|
|
0
|
110 with keymap-2
|
|
|
111 keymap-2: associates "a" with the command
|
|
|
112
|
|
|
113 Note that a special exception is made for the meta modifier, in order
|
|
|
114 to deal with ESC/meta lossage. Any key combination containing the
|
|
|
115 meta modifier is first indexed off of the main map into the meta
|
|
70
|
116 submap (with hash key MOD_META) and then indexed off of the
|
|
0
|
117 meta submap with the meta modifier removed from the key combination.
|
|
|
118 For example, when associating a command with C-M-H-a, we'd have
|
|
|
119
|
|
70
|
120 keymap-1: associates the integer MOD_META with keymap-2
|
|
|
121 keymap-2: associates the integer (MOD_CONTROL | MOD_HYPER)
|
|
0
|
122 with keymap-3
|
|
|
123 keymap-3: associates "a" with the command
|
|
|
124
|
|
|
125 Note that keymap-2 might have normal bindings in it; these would be
|
|
|
126 for key combinations containing only the meta modifier, such as
|
|
|
127 M-y or meta-backspace.
|
|
|
128
|
|
|
129 If the command that "a" was bound to in keymap-3 was itself a keymap,
|
|
|
130 then that would make the key "C-M-H-a" be a prefix character.
|
|
|
131
|
|
|
132 Note that this new model of keymaps takes much of the magic away from
|
|
|
133 the Escape key: the value of the variable `esc-map' is no longer indexed
|
|
|
134 in the `global-map' under the ESC key. It's indexed under the integer
|
|
70
|
135 MOD_META. This is not user-visible, however; none of the "bucky"
|
|
0
|
136 maps are.
|
|
|
137
|
|
|
138 There is a hack in Flookup_key() that makes (lookup-key global-map "\^[")
|
|
|
139 and (define-key some-random-map "\^[" my-esc-map) work as before, for
|
|
|
140 compatibility.
|
|
|
141
|
|
|
142 Since keymaps are opaque, the only way to extract information from them
|
|
|
143 is with the functions lookup-key, key-binding, local-key-binding, and
|
|
|
144 global-key-binding, which work just as before, and the new function
|
|
|
145 map-keymap, which is roughly analagous to maphash.
|
|
|
146
|
|
|
147 Note that map-keymap perpetuates the illusion that the "bucky" submaps
|
|
|
148 don't exist: if you map over a keymap with bucky submaps, it will also
|
|
|
149 map over those submaps. It does not, however, map over other random
|
|
|
150 submaps of the keymap, just the bucky ones.
|
|
|
151
|
|
|
152 One implication of this is that when you map over `global-map', you will
|
|
|
153 also map over `esc-map'. It is merely for compatibility that the esc-map
|
|
|
154 is accessible at all; I think that's a bad thing, since it blurs the
|
|
|
155 distinction between ESC and "meta" even more. "M-x" is no more a two-
|
|
|
156 key sequence than "C-x" is.

1710 Define key sequence KEYS, in KEYMAP, as DEF.
|
|
|
1711 KEYMAP is a keymap object.
|
|
|
1712 KEYS is the sequence of keystrokes to bind, described below.
|
|
|
1713 DEF is anything that can be a key's definition:
|
|
|
1714 nil (means key is undefined in this keymap);
|
|
|
1715 a command (a Lisp function suitable for interactive calling);
|
|
|
1716 a string or key sequence vector (treated as a keyboard macro);
|
|
|
1717 a keymap (to define a prefix key);
|
|
|
1718 a symbol; when the key is looked up, the symbol will stand for its
|
|
|
1719 function definition, that should at that time be one of the above,
|
|
|
1720 or another symbol whose function definition is used, and so on.
|
|
|
1721 a cons (STRING . DEFN), meaning that DEFN is the definition
|
|
|
1722 (DEFN should be a valid definition in its own right);
|
|
|
1723 or a cons (KEYMAP . CHAR), meaning use definition of CHAR in map KEYMAP.
|
|
|
1724
|
|
|
1725 Contrary to popular belief, the world is not ASCII. When running under a
|
|
|
1726 window manager, XEmacs can tell the difference between, for example, the
|
|
|
1727 keystrokes control-h, control-shift-h, and backspace. You can, in fact,
|
|
|
1728 bind different commands to each of these.
|
|
|
1729
|
|
|
1730 A `key sequence' is a set of keystrokes. A `keystroke' is a keysym and some
|
|
|
1731 set of modifiers (such as control and meta). A `keysym' is what is printed
|
|
|
1732 on the keys on your keyboard.
|
|
|
1733
|
|
|
1734 A keysym may be represented by a symbol, or (if and only if it is equivalent
|
|
|
1735 to an ASCII character in the range 32 - 255) by a character or its equivalent
|
|
|
1736 ASCII code. The `A' key may be represented by the symbol `A', the character
|
|
|
1737 `?A', or by the number 65. The `break' key may be represented only by the
|
|
|
1738 symbol `break'.
|
|
|
1739
|
|
|
1740 A keystroke may be represented by a list: the last element of the list
|
|
|
1741 is the key (a symbol, character, or number, as above) and the
|
|
|
1742 preceding elements are the symbolic names of modifier keys (control,
|
|
|
1743 meta, super, hyper, alt, and shift). Thus, the sequence control-b is
|
|
|
1744 represented by the forms `(control b)', `(control ?b)', and `(control
|
|
|
1745 98)'. A keystroke may also be represented by an event object, as
|
|
|
1746 returned by the `next-command-event' and `read-key-sequence'
|
|
|
1747 functions.
|
|
|
1748
|
|
|
1749 Note that in this context, the keystroke `control-b' is *not* represented
|
|
|
1750 by the number 2 (the ASCII code for ^B) or the character `?\^B'. See below.
|
|
|
1751
|
|
|
1752 The `shift' modifier is somewhat of a special case. You should not (and
|
|
|
1753 cannot) use `(meta shift a)' to mean `(meta A)', since for characters that
|
|
|
1754 have ASCII equivalents, the state of the shift key is implicit in the
|
|
|
1755 keysym (a vs. A). You also cannot say `(shift =)' to mean `+', as that
|
|
|
1756 sort of thing varies from keyboard to keyboard. The shift modifier is for
|
|
|
1757 use only with characters that do not have a second keysym on the same key,
|
|
|
1758 such as `backspace' and `tab'.
|
|
|
1759
|
|
|
1760 A key sequence is a vector of keystrokes. As a degenerate case, elements
|
|
|
1761 of this vector may also be keysyms if they have no modifiers. That is,
|
|
|
1762 the `A' keystroke is represented by all of these forms:
|
|
|
1763 A ?A 65 (A) (?A) (65)
|
|
|
1764 [A] [?A] [65] [(A)] [(?A)] [(65)]
|
|
|
1765
|
|
|
1766 the `control-a' keystroke is represented by these forms:
|
|
|
1767 (control A) (control ?A) (control 65)
|
|
|
1768 [(control A)] [(control ?A)] [(control 65)]
|
|
|
1769 the key sequence `control-c control-a' is represented by these forms:
|
|
|
1770 [(control c) (control a)] [(control ?c) (control ?a)]
|
|
|
1771 [(control 99) (control 65)] etc.
|
|
|
1772
|
|
|
1773 Mouse button clicks work just like keypresses: (control button1) means
|
|
|
1774 pressing the left mouse button while holding down the control key.
|
|
|
1775 \[(control c) (shift button3)] means control-c, hold shift, click right.
|
|
|
1776
|
|
|
1777 Commands may be bound to the mouse-button up-stroke rather than the down-
|
|
|
1778 stroke as well. `button1' means the down-stroke, and `button1up' means the
|
|
|
1779 up-stroke. Different commands may be bound to the up and down strokes,
|
|
|
1780 though that is probably not what you want, so be careful.
|
|
|
1781
|
|
|
1782 For backward compatibility, a key sequence may also be represented by a
|
|
|
1783 string. In this case, it represents the key sequence(s) that would
|
|
|
1784 produce that sequence of ASCII characters in a purely ASCII world. For
|
|
|
1785 example, a string containing the ASCII backspace character, \"\\^H\", would
|
|
|
1786 represent two key sequences: `(control h)' and `backspace'. Binding a
|
|
|
1787 command to this will actually bind both of those key sequences. Likewise
|
|
|
1788 for the following pairs:
|
|
|
1789
|
|
|
1790 control h backspace
|
|
|
1791 control i tab
|
|
|
1792 control m return
|
|
|
1793 control j linefeed
|
|
|
1794 control [ escape
|
|
|
1795 control @ control space
|
|
|
1796
|
|
|
1797 After binding a command to two key sequences with a form like
|
|
|
1798
|
|
|
1799 (define-key global-map \"\\^X\\^I\" \'command-1)
|
|
|
1800
|
|
|
1801 it is possible to redefine only one of those sequences like so:
|
|
|
1802
|
|
|
1803 (define-key global-map [(control x) (control i)] \'command-2)
|
|
|
1804 (define-key global-map [(control x) tab] \'command-3)
|
|
|
1805
|
|
|
1806 Of course, all of this applies only when running under a window system. If
|
|
|
1807 you're talking to XEmacs through a TTY connection, you don't get any of
|
|
|
1808 these features.

2720 prefix key, it's not entirely objvious what map-keymap should do, but
|
|
|
2721 what it does is: map over all keys in this map; then recursively map
|
|
|
2722 over all submaps of this map that are "bucky" submaps. This means that,
|
|
|
2723 when mapping over a keymap, it appears that "x" and "C-x" are in the
|
|
|
2724 same map, although "C-x" is really in the "control" submap of this one.
|
|
|
2725 However, since we don't recursively descend the submaps that are bound
|
|
|
2726 to prefix keys (like C-x, C-h, etc) the caller will have to recurse on
|
|

2727 those explicitly, if that's what they want.

2731 invisible from elisp. They're just an implementation detail that code

2732 outside of this file doesn't need to know about.
