| 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. | |

| 1633 \(2) If KEY-SPECIFIER is a character or integer, | |

| 1635 compared to get the result. The reason for special-casing this and doing | |
| 1636 it this way is to ensure that, e.g., a KEY-SPECIFIER of 27 matches both | |
| 1637 a key-press `escape' and a key-press `control ['. #### Think about META | |
| 1638 argument to event-to-character. | |
| 1639 | |
| 1640 \(3) If KEY-SPECIFIER is an event, fine; else, convert to an event using | |
| 1641 \(character-to-event KEY-SPECIFIER nil nil nil). If EVENT is not on a TTY, | |
| 1642 we just compare keysyms and modifiers and return yes if both are equal. | |
| 1643 For TTY, we do character-level comparison by converting both to a character | |
| 1644 with (event-to-character ... nil nil nil) and comparing the characters. | |

| 1765 KEYMAP is a keymap object. | |
| 3086 | 1766 KEYS is the key sequence to bind, described below. |
| 428 | 1767 DEF is anything that can be a key's definition: |
| 1768 nil (means key is undefined in this keymap); | |
| 1769 a command (a Lisp function suitable for interactive calling); | |
| 1770 a string or key sequence vector (treated as a keyboard macro); | |
| 1771 a keymap (to define a prefix key); | |
| 1772 a symbol; when the key is looked up, the symbol will stand for its | |
| 1773 function definition, that should at that time be one of the above, | |
| 1774 or another symbol whose function definition is used, and so on. | |
| 1775 a cons (STRING . DEFN), meaning that DEFN is the definition | |
| 1776 (DEFN should be a valid definition in its own right); | |
| 1777 or a cons (KEYMAP . CHAR), meaning use definition of CHAR in map KEYMAP. | |
| 1778 | |
| 3086 | 1779 A `key sequence' is a vector of one or more keystrokes. |
| 1780 A `keystroke' is a list containing a key and zero or more modifiers. The | |
| 1781 key must be the last element of the list. | |
| 1782 A `key' is a symbol corresponding to a key on the keyboard, or to a mouse | |
| 1783 gesture. Mouse clicks are denoted by symbols prefixed with "button", | |
| 1784 followed by a digit for which button, and optionally "up". Thus `button1' | |
| 1785 means the down-stroke and `button1up' means the up-stroke when clicking | |
| 1786 mouse button 1. | |
| 1787 A `modifier' is a symbol naming a physical key which is only "noticed" by | |
| 1788 XEmacs when chorded with another key. The `shift' modifier is a special | |
| 1789 case. You cannot use `(meta shift a)' to mean `(meta A)', since for | |
| 1790 characters that have ASCII equivalents, the state of the shift key is | |
| 1791 implicit in the keysym (a vs. A). You also cannot say `(shift =)' to mean | |
| 1792 `+', as that correspondence varies from keyboard to keyboard. The shift | |
| 1793 modifier can only be applied to keys that do not have a second keysym on the | |
| 1794 same key, such as `backspace' and `tab'. A mouse click may be combined with | |
| 1795 modifiers to create a compound "keystroke". | |
| 1796 | |
| 1797 The keys, mouse gestures, and modifiers that are available depend on your | |
| 1798 console and its driver. At a minimum the ASCII graphic characters will be | |
| 1799 available as keys, and shift, control, and meta as modifiers. | |
| 1800 | |
| 1801 To find out programmatically what a key is bound to, use `key-binding' to | |
| 1802 check all applicable keymaps, or `lookup-key' to check a specific keymap. | |
| 1803 The documentation for `key-binding' also contains a description of which | |
| 1804 keymaps are applicable in various situations. `where-is-internal' does | |
| 1805 the opposite of `key-binding', i.e. searches keymaps for the keys that | |
| 1806 map to a particular binding. | |
| 1807 | |
| 1808 If you are confused about why a particular key sequence is generating a | |
| 1809 particular binding, and looking through the keymaps doesn't help, setting | |
| 1810 the variable `debug-emacs-events' may help. If not, try checking | |
| 1811 what's in `function-key-map' and `key-translation-map'. | |
| 1812 | |
| 1813 When running under a window system, typically the repertoire of keys is | |
| 1814 vastly expanded. XEmacs does its best to use the names defined on each | |
| 1815 platform. Also, when running under a window system, XEmacs can tell the | |
| 1816 difference between the keystrokes control-h, control-shift-h, and backspace. | |
| 1817 If the symbols differ, you can bind different actions to each. For mouse | |
| 1818 clicks, different commands may be bound to the up and down strokes, though | |
| 1819 that is probably not what you want, so be careful. | |
| 1820 | |
| 1821 Variant representations: | |
| 1822 | |
| 1823 Besides the canonical representation as a vector of lists of symbols, | |
| 1824 `define-key' also accepts a number of abbreviations, aliases, and variants | |
| 1825 for convenience, compatibility, and internal use. | |
| 1826 | |
| 1827 A keystroke may be represented by a key; this is treated as though it were a | |
| 1828 list containing that key as the only element. A keystroke may also be | |
| 1829 represented by an event object, as returned by the `next-command-event' and | |
| 1830 `read-key-sequence' functions. A key sequence may be represented by a | |
| 1831 single keystroke; this is treated as a vector containing that keystroke as | |
| 1832 its only element. | |
| 1833 | |
| 1834 A key may be represented by a character or its equivalent integer code, | |
| 1835 if and only if it is equivalent to a character with a code in the range | |
| 1836 32 - 255. | |
| 1837 | |
| 1838 For backward compatibility, a key sequence may also be represented by a | |
| 1839 string. In this case, it represents the key sequence(s) that would | |
| 1840 produce that sequence of ASCII characters in a purely ASCII world. An | |
| 1841 alternative string representation is keyboard macro notation, which can | |
| 1842 be translated to the canonical representation with `kbd'. | |
| 1843 | |
| 1844 Examples: | |
| 1845 | |
| 1846 The key sequence `A' (which invokes `self-insert-command') is represented | |
| 1847 by all of these forms: | |
| 428 | 1848 A ?A 65 (A) (?A) (65) |
| 1849 [A] [?A] [65] [(A)] [(?A)] [(65)] | |
| 1850 | |
| 3086 | 1851 The key sequence `control-a' is represented by these forms: |
| 428 | 1852 (control A) (control ?A) (control 65) |
| 1853 [(control A)] [(control ?A)] [(control 65)] | |
| 3086 | 1854 |
| 1855 The key sequence `control-c control-a' is represented by these forms: | |
| 428 | 1856 [(control c) (control a)] [(control ?c) (control ?a)] |
| 1857 [(control 99) (control 65)] etc. | |
| 1858 | |
| 3086 | 1859 The keystroke `control-b' *may not* be represented by the number 2 (the |
| 1860 ASCII code for ^B) or the character `?\^B'. | |
| 1861 | |
| 1862 The `break' key may be represented only by the symbol `break'. | |
| 1863 | |
| 428 | 1864 Mouse button clicks work just like keypresses: (control button1) means |
| 1865 pressing the left mouse button while holding down the control key. | |
| 3086 | 1866 |
| 1867 A string containing the ASCII backspace character, "\\^H", would represent | |
| 1868 two key sequences: `(control h)' and `backspace'. Binding a | |
| 428 | 1869 command to this will actually bind both of those key sequences. Likewise |
| 1870 for the following pairs: | |
| 1871 | |
| 1872 control h backspace | |
| 1873 control i tab | |
| 1874 control m return | |
| 1875 control j linefeed | |
| 1876 control [ escape | |
| 1877 control @ control space | |
| 1878 | |
| 1879 After binding a command to two key sequences with a form like | |
| 1880 | |
| 1881 (define-key global-map "\\^X\\^I" \'command-1) | |
| 1882 | |
| 1883 it is possible to redefine only one of those sequences like so: | |
| 1884 | |
| 1885 (define-key global-map [(control x) (control i)] \'command-2) | |
| 1886 (define-key global-map [(control x) tab] \'command-3) | |

| 428 | 2615 happened over a toolbar); |
| 444 | 2616 - the current local map of the buffer under the mouse (does not |
| 428 | 2617 apply to toolbar clicks); |
| 2618 - any applicable minor-mode maps; | |
| 771 | 2619 - either `global-tty-map' or `global-window-system-map', depending on |
| 2620 whether the current console is a TTY or non-TTY console; | |
| 428 | 2621 - the current global map. |
| 2622 | |
| 2623 Note that if `overriding-local-map' or `overriding-terminal-local-map' | |
| 2624 is non-nil, *only* those two maps and the current global map are searched. | |
| 771 | 2625 |
| 2626 Note also that key sequences actually received from the keyboard driver | |
| 2627 may be processed in various ways to generate the key sequence that is | |
| 2628 actually looked up in the keymaps. In particular: | |
| 2629 | |
| 2630 -- Keysyms are individually passed through `keyboard-translate-table' before | |
| 2631 any other processing. | |
| 2632 -- After this, key sequences as a whole are passed through | |
| 2633 `key-translation-map'. | |
| 2634 -- The resulting key sequence is actually looked up in the keymaps. | |
| 2635 -- If there's no binding found, the key sequence is passed through | |
| 2636 `function-key-map' and looked up again. | |
| 2637 -- If no binding is found and `retry-undefined-key-binding-unshifted' is | |
| 2638 set (it usually is) and the final keysym is an uppercase character, | |
| 2639 we lowercase it and start over from the `key-translation-map' stage. | |
| 2640 -- If no binding is found and we're on MS Windows and have international | |
| 2641 support, we successively remap the key sequence using the keyboard layouts | |
| 2642 of various default locales (current language environment, user default, | |
| 2643 system default, US ASCII) and try again. This makes (e.g.) sequences | |
| 2644 such as `C-x b' work in a Russian locale, where the alphabetic keys are | |
| 2645 actually generating Russian characters and not the Roman letters written | |
| 2646 on the keycaps. (Not yet implemented) | |
| 2647 -- Finally, if the last keystroke matches `help-char', we automatically | |
| 2648 generate and display a list of possible key sequences and bindings | |
| 2649 given the prefix so far generated. | |
