44 /* A keymap contains six slots:
|
|
|
45
|
|
|
46 parents Ordered list of keymaps to search after
|
|
|
47 this one if no match is found.
|
|
|
48 Keymaps can thus be arranged in a hierarchy.
|
|
|
49
|
|
|
50 table A hash table, hashing keysyms to their bindings.
|
|
|
51 It will be one of the following:
|
|
|
52
|
|
3025
|
53 -- a symbol, e.g. `home'
|
|
428
|
54 -- a character, representing something printable
|
|
|
55 (not ?\C-c meaning C-c, for instance)
|
|
|
56 -- an integer representing a modifier combination
|
|
|
57
|
|
|
58 inverse_table A hash table, hashing bindings to the list of keysyms
|
|
|
59 in this keymap which are bound to them. This is to make
|
|
|
60 the Fwhere_is_internal() function be fast. It needs to be
|
|
|
61 fast because we want to be able to call it in realtime to
|
|
|
62 update the keyboard-equivalents on the pulldown menus.
|
|
|
63 Values of the table are either atoms (keysyms)
|
|
|
64 or a dotted list of keysyms.
|
|
|
65
|
|
|
66 sub_maps_cache An alist; for each entry in this keymap whose binding is
|
|
|
67 a keymap (that is, Fkeymapp()) this alist associates that
|
|
|
68 keysym with that binding. This is used to optimize both
|
|
|
69 Fwhere_is_internal() and Faccessible_keymaps(). This slot
|
|
|
70 gets set to the symbol `t' every time a change is made to
|
|
|
71 this keymap, causing it to be recomputed when next needed.
|
|
|
72
|
|
|
73 prompt See `set-keymap-prompt'.
|
|
|
74
|
|
|
75 default_binding See `set-keymap-default-binding'.
|
|
|
76
|
|
|
77 Sequences of keys are stored in the obvious way: if the sequence of keys
|
|
|
78 "abc" was bound to some command `foo', the hierarchy would look like
|
|
|
79
|
|
|
80 keymap-1: associates "a" with keymap-2
|
|
|
81 keymap-2: associates "b" with keymap-3
|
|
|
82 keymap-3: associates "c" with foo
|
|
|
83
|
|
|
84 However, bucky bits ("modifiers" to the X-minded) are represented in the
|
|
|
85 keymap hierarchy as well. (This lets us use EQable objects as hash keys.)
|
|
|
86 Each combination of modifiers (e.g. control-hyper) gets its own submap
|
|
|
87 off of the main map. The hash key for a modifier combination is
|
|
|
88 an integer, computed by MAKE_MODIFIER_HASH_KEY().
|
|
|
89
|
|
|
90 If the key `C-a' was bound to some command, the hierarchy would look like
|
|
|
91
|
|
442
|
92 keymap-1: associates the integer XEMACS_MOD_CONTROL with keymap-2
|
|
428
|
93 keymap-2: associates "a" with the command
|
|
|
94
|
|
|
95 Similarly, if the key `C-H-a' was bound to some command, the hierarchy
|
|
|
96 would look like
|
|
|
97
|
|
442
|
98 keymap-1: associates the integer (XEMACS_MOD_CONTROL | XEMACS_MOD_HYPER)
|
|
428
|
99 with keymap-2
|
|
|
100 keymap-2: associates "a" with the command
|
|
|
101
|
|
|
102 Note that a special exception is made for the meta modifier, in order
|
|
|
103 to deal with ESC/meta lossage. Any key combination containing the
|
|
|
104 meta modifier is first indexed off of the main map into the meta
|
|
442
|
105 submap (with hash key XEMACS_MOD_META) and then indexed off of the
|
|
428
|
106 meta submap with the meta modifier removed from the key combination.
|
|
|
107 For example, when associating a command with C-M-H-a, we'd have
|
|
|
108
|
|
442
|
109 keymap-1: associates the integer XEMACS_MOD_META with keymap-2
|
|
|
110 keymap-2: associates the integer (XEMACS_MOD_CONTROL | XEMACS_MOD_HYPER)
|
|
428
|
111 with keymap-3
|
|
|
112 keymap-3: associates "a" with the command
|
|
|
113
|
|
|
114 Note that keymap-2 might have normal bindings in it; these would be
|
|
|
115 for key combinations containing only the meta modifier, such as
|
|
|
116 M-y or meta-backspace.
|
|
|
117
|
|
|
118 If the command that "a" was bound to in keymap-3 was itself a keymap,
|
|
|
119 then that would make the key "C-M-H-a" be a prefix character.
|
|
|
120
|
|
|
121 Note that this new model of keymaps takes much of the magic away from
|
|
|
122 the Escape key: the value of the variable `esc-map' is no longer indexed
|
|
|
123 in the `global-map' under the ESC key. It's indexed under the integer
|
|
442
|
124 XEMACS_MOD_META. This is not user-visible, however; none of the "bucky"
|
|
428
|
125 maps are.
|
|
|
126
|
|
|
127 There is a hack in Flookup_key() that makes (lookup-key global-map "\^[")
|
|
|
128 and (define-key some-random-map "\^[" my-esc-map) work as before, for
|
|
|
129 compatibility.
|
|
|
130
|
|
|
131 Since keymaps are opaque, the only way to extract information from them
|
|
|
132 is with the functions lookup-key, key-binding, local-key-binding, and
|
|
|
133 global-key-binding, which work just as before, and the new function
|
|
440
|
134 map-keymap, which is roughly analogous to maphash.
|
|
428
|
135
|
|
|
136 Note that map-keymap perpetuates the illusion that the "bucky" submaps
|
|
|
137 don't exist: if you map over a keymap with bucky submaps, it will also
|
|
|
138 map over those submaps. It does not, however, map over other random
|
|
|
139 submaps of the keymap, just the bucky ones.
|
|
|
140
|
|
|
141 One implication of this is that when you map over `global-map', you will
|
|
|
142 also map over `esc-map'. It is merely for compatibility that the esc-map
|
|
|
143 is accessible at all; I think that's a bad thing, since it blurs the
|
|
|
144 distinction between ESC and "meta" even more. "M-x" is no more a two-
|
|
|
145 key sequence than "C-x" is.

1639 This can be useful, e.g., to determine if the user pressed `help-char' or

|

1641
|

1642 KEY-SPECIFIER can be a character, integer, a symbol, a list of modifiers
|

1643 and symbols, or an event.
|

1644

1645 What this actually happens is this:
|
|
|
1646
|
|

1647 \(1) Return no, if EVENT is not a key press event or if KEY-SPECIFIER is nil
|
|
|
1648 or an integer that cannot be converted to a character.

1649
|
|
|
1650 \(2) If KEY-SPECIFIER is a character or integer,
|
|
|
1651 (event-to-character EVENT nil nil nil) is called, and the characters are
|
|
|
1652 compared to get the result. The reason for special-casing this and doing
|
|
|
1653 it this way is to ensure that, e.g., a KEY-SPECIFIER of 27 matches both
|
|
|
1654 a key-press `escape' and a key-press `control ['. #### Think about META
|
|
|
1655 argument to event-to-character.
|
|
|
1656
|
|
|
1657 \(3) If KEY-SPECIFIER is an event, fine; else, convert to an event using
|
|
|
1658 \(character-to-event KEY-SPECIFIER nil nil nil). If EVENT is not on a TTY,
|
|
|
1659 we just compare keysyms and modifiers and return yes if both are equal.
|
|

1660 For TTY, we do character-level comparison by converting both to a character

1661 with (event-to-character ... nil nil nil) and comparing the characters.

1796 Contrary to popular belief, the world is not ASCII. When running under a
|
|
771
|
1797 window system, XEmacs can tell the difference between, for example, the
|
|
428
|
1798 keystrokes control-h, control-shift-h, and backspace. You can, in fact,
|
|
|
1799 bind different commands to each of these.
|
|
|
1800
|
|
|
1801 A `key sequence' is a set of keystrokes. A `keystroke' is a keysym and some
|
|
|
1802 set of modifiers (such as control and meta). A `keysym' is what is printed
|
|
|
1803 on the keys on your keyboard.
|
|
|
1804
|
|
|
1805 A keysym may be represented by a symbol, or (if and only if it is equivalent
|
|
2828
|
1806 to a character with a code in the range 32 - 255) by a character or its
|
|
|
1807 equivalent code. The `A' key may be represented by the symbol `A', the
|
|
|
1808 character `?A', or by the number 65. The `break' key may be represented
|
|
|
1809 only by the symbol `break'.
|
|
428
|
1810
|
|
|
1811 A keystroke may be represented by a list: the last element of the list
|
|
|
1812 is the key (a symbol, character, or number, as above) and the
|
|
|
1813 preceding elements are the symbolic names of modifier keys (control,
|
|
|
1814 meta, super, hyper, alt, and shift). Thus, the sequence control-b is
|
|
|
1815 represented by the forms `(control b)', `(control ?b)', and `(control
|
|
|
1816 98)'. A keystroke may also be represented by an event object, as
|
|
|
1817 returned by the `next-command-event' and `read-key-sequence'
|
|
|
1818 functions.
|
|
|
1819
|
|
|
1820 Note that in this context, the keystroke `control-b' is *not* represented
|
|
|
1821 by the number 2 (the ASCII code for ^B) or the character `?\^B'. See below.
|
|
|
1822
|
|
|
1823 The `shift' modifier is somewhat of a special case. You should not (and
|
|
|
1824 cannot) use `(meta shift a)' to mean `(meta A)', since for characters that
|
|
|
1825 have ASCII equivalents, the state of the shift key is implicit in the
|
|
|
1826 keysym (a vs. A). You also cannot say `(shift =)' to mean `+', as that
|
|
|
1827 sort of thing varies from keyboard to keyboard. The shift modifier is for
|
|
|
1828 use only with characters that do not have a second keysym on the same key,
|
|
|
1829 such as `backspace' and `tab'.
|
|
|
1830
|
|
|
1831 A key sequence is a vector of keystrokes. As a degenerate case, elements
|
|
|
1832 of this vector may also be keysyms if they have no modifiers. That is,
|
|
|
1833 the `A' keystroke is represented by all of these forms:
|
|
|
1834 A ?A 65 (A) (?A) (65)
|
|
|
1835 [A] [?A] [65] [(A)] [(?A)] [(65)]
|
|
|
1836
|
|
|
1837 the `control-a' keystroke is represented by these forms:
|
|
|
1838 (control A) (control ?A) (control 65)
|
|
|
1839 [(control A)] [(control ?A)] [(control 65)]
|
|
|
1840 the key sequence `control-c control-a' is represented by these forms:
|
|
|
1841 [(control c) (control a)] [(control ?c) (control ?a)]
|
|
|
1842 [(control 99) (control 65)] etc.
|
|
|
1843
|
|
|
1844 Mouse button clicks work just like keypresses: (control button1) means
|
|
|
1845 pressing the left mouse button while holding down the control key.
|
|
|
1846 \[(control c) (shift button3)] means control-c, hold shift, click right.
|
|
|
1847
|
|
|
1848 Commands may be bound to the mouse-button up-stroke rather than the down-
|
|
|
1849 stroke as well. `button1' means the down-stroke, and `button1up' means the
|
|
|
1850 up-stroke. Different commands may be bound to the up and down strokes,
|
|
|
1851 though that is probably not what you want, so be careful.
|
|
|
1852
|
|
|
1853 For backward compatibility, a key sequence may also be represented by a
|
|
|
1854 string. In this case, it represents the key sequence(s) that would
|
|
|
1855 produce that sequence of ASCII characters in a purely ASCII world. For
|
|
|
1856 example, a string containing the ASCII backspace character, "\\^H", would
|
|
|
1857 represent two key sequences: `(control h)' and `backspace'. Binding a
|
|
|
1858 command to this will actually bind both of those key sequences. Likewise
|
|
|
1859 for the following pairs:
|
|
|
1860
|
|
|
1861 control h backspace
|
|
|
1862 control i tab
|
|
|
1863 control m return
|
|
|
1864 control j linefeed
|
|
|
1865 control [ escape
|
|
|
1866 control @ control space
|
|
|
1867
|
|
|
1868 After binding a command to two key sequences with a form like
|
|
|
1869
|
|
|
1870 (define-key global-map "\\^X\\^I" \'command-1)
|
|
|
1871
|
|
|
1872 it is possible to redefine only one of those sequences like so:
|
|
|
1873
|
|
|
1874 (define-key global-map [(control x) (control i)] \'command-2)
|
|
|
1875 (define-key global-map [(control x) tab] \'command-3)
|
|
|
1876
|
|
|
1877 Of course, all of this applies only when running under a window system. If
|
|
|
1878 you're talking to XEmacs through a TTY connection, you don't get any of
|
|
|
1879 these features.
|
|
771
|
1880
|
|
|
1881 To find out programmatically what a key is bound to, use `key-binding' to
|
|
|
1882 check all applicable keymaps, or `lookup-key' to check a specific keymap.
|
|
|
1883 The documentation for `key-binding' also contains a description of which
|
|
|
1884 keymaps are applicable in various situations. `where-is-internal' does
|
|
|
1885 the opposite of `key-binding', i.e. searches keymaps for the keys that
|
|
|
1886 map to a particular binding.
|
|
|
1887
|
|
|
1888 If you are confused about why a particular key sequence is generating a
|
|
|
1889 particular binding, and looking through the keymaps doesn't help, setting
|
|
|
1890 the variable `debug-emacs-events' may help. If not, try checking
|
|
|
1891 what's in `function-key-map' and `key-translation-map'.

428
|
2610 - the current global map.

|

|
2612 For mouse-clicks, the order of keymaps searched is:

2613 - the current-local-map of the `mouse-grabbed-buffer' if any;
|
|
|
2614 - vertical-divider-map, if the event happened over a vertical divider
|
|
|
2615 - the `keymap' property of any extent(s) at the position of the click
|
|
|
2616 (this includes modeline extents);
|
|
|
2617 - the modeline-map of the buffer corresponding to the modeline under
|
|

2618 the mouse (if the click happened over a modeline);
|

444

2621 - the current local map of the buffer under the mouse (does not

2623 - any applicable minor-mode maps;

2625 whether the current console is a TTY or non-TTY console;

|
|

2632 may be processed in various ways to generate the key sequence that is
|
|
|
2633 actually looked up in the keymaps. In particular:
|
|
|
2634
|
|
|
2635 -- Keysyms are individually passed through `keyboard-translate-table' before
|
|
|
2636 any other processing.
|
|
|
2637 -- After this, key sequences as a whole are passed through
|
|
|
2638 `key-translation-map'.
|
|
|
2639 -- The resulting key sequence is actually looked up in the keymaps.
|
|
|
2640 -- If there's no binding found, the key sequence is passed through
|
|
|
2641 `function-key-map' and looked up again.
|
|
|
2642 -- If no binding is found and `retry-undefined-key-binding-unshifted' is
|
|
|
2643 set (it usually is) and the final keysym is an uppercase character,
|
|
|
2644 we lowercase it and start over from the `key-translation-map' stage.
|
|
|
2645 -- If no binding is found and we're on MS Windows and have international
|
|
|
2646 support, we successively remap the key sequence using the keyboard layouts
|
|
|
2647 of various default locales (current language environment, user default,
|
|
|
2648 system default, US ASCII) and try again. This makes (e.g.) sequences
|
|
|
2649 such as `C-x b' work in a Russian locale, where the alphabetic keys are
|
|
|
2650 actually generating Russian characters and not the Roman letters written
|
|
|
2651 on the keycaps. (Not yet implemented)
|
|
|
2652 -- Finally, if the last keystroke matches `help-char', we automatically
|
|
|
2653 generate and display a list of possible key sequences and bindings
|
|
|
2654 given the prefix so far generated.

2825 what it does is: map over all keys in this map; then recursively map

2826 over all submaps of this map that are "bucky" submaps. This means that,
