34 * The xkb_keycodes section
35 * ========================
37 * This is the simplest section type, and is the first one to be
38 * compiled. The purpose of this is mostly to map between the
39 * hardware/evdev scancodes and xkb keycodes. Each key is given a name
40 * of up to 4 letters, by which it can be referred to later, e.g. in the
43 * Minimum/Maximum keycode
44 * -----------------------
45 * Statements of the form:
49 * The file may explicitly declare the minimum and/or maximum keycode
50 * contained therein (traditionally 8-255, inherited from old xfree86
51 * keycodes). If these are stated explicitly, they are enforced. If
52 * they are not stated, they are computed automatically.
56 * Statements of the form:
60 * The above would let 49 and 10 be valid keycodes in the keymap, and
61 * assign them the names TLDE and AE01 respectively. The format <WXYZ> is
62 * always used to refer to a key by name.
64 * [ The naming convention <AE01> just denoted the position of the key
65 * in the main alphanumric section of the keyboard, with the top left key
66 * (usually "~") acting as origin. <AE01> is the key in the first row
67 * second column (which is usually "1"). ]
69 * In the common case this just maps to the evdev scancodes from
70 * /usr/include/linux/input.h, e.g. the following definitions:
71 * #define KEY_GRAVE 41
73 * Similar definitions appear in the xf86-input-keyboard driver. Note
74 * that in all current keymaps there's a constant offset of 8 (for
75 * historical reasons).
77 * If there's a conflict, like the same name given to different keycodes,
78 * or same keycode given different names, it is resolved according to the
79 * merge mode which applies to the definitions.
81 * The reason for the 4 characters limit is that the name is sometimes
82 * converted to an unsigned long (in a direct mapping), instead of a char
83 * array (see KeyNameToLong, LongToKeyName).
87 * Statements of the form:
88 * alias <MENU> = <COMP>;
90 * Allows to refer to a previously defined key (here <COMP>) by another
91 * name (here <MENU>). Conflicts are handled similarly.
93 * Indicator name statements
94 * -------------------------
95 * Statements of the form:
96 * indicator 1 = "Caps Lock";
97 * indicator 2 = "Num Lock";
98 * indicator 3 = "Scroll Lock";
100 * Assigns a name the indicator (i.e. keyboard LED) with the given index.
101 * The amount of possible indicators is predetermined (XkbNumIndicators).
102 * The indicator may be referred by this name later in the compat section
105 * Effect on the keymap
106 * --------------------
107 * After all of the xkb_keycodes sections have been compiled, the
108 * following members of struct xkb_keymap are finalized:
109 * xkb_keycode_t min_key_code;
110 * xkb_keycode_t max_key_code;
111 * darray(struct xkb_key_alias) key_aliases;
112 * const char *indicator_names[XkbNumIndicators];
113 * char *keycodes_section_name;
114 * Further, the array of keys:
115 * darray(struct xkb_key) keys;
116 * had been resized to its final size (i.e. all of the xkb_key objects are
117 * referable by their keycode). However the objects themselves do not
118 * contain any useful information besides the key name at this point.
