32 * The xkb_keycodes section
33 * ========================
35 * This is the simplest section type, and is the first one to be
36 * compiled. The purpose of this is mostly to map between the
37 * hardware/evdev scancodes and xkb keycodes. Each key is given a name
38 * of up to 4 letters, by which it can be referred to later, e.g. in the
41 * Minimum/Maximum keycode
42 * -----------------------
43 * Statements of the form:
47 * The file may explicitly declare the minimum and/or maximum keycode
48 * contained therein (traditionally 8-255, inherited from old xfree86
49 * keycodes). If these are stated explicitly, they are enforced. If
50 * they are not stated, they are computed automatically.
54 * Statements of the form:
58 * The above would let 49 and 10 be valid keycodes in the keymap, and
59 * assign them the names TLDE and AE01 respectively. The format <WXYZ> is
60 * always used to refer to a key by name.
62 * [ The naming convention <AE01> just denoted the position of the key
63 * in the main alphanumric section of the keyboard, with the top left key
64 * (usually "~") acting as origin. <AE01> is the key in the first row
65 * second column (which is usually "1"). ]
67 * In the common case this just maps to the evdev scancodes from
68 * /usr/include/linux/input.h, e.g. the following definitions:
69 * #define KEY_GRAVE 41
71 * Similar definitions appear in the xf86-input-keyboard driver. Note
72 * that in all current keymaps there's a constant offset of 8 (for
73 * historical reasons).
75 * If there's a conflict, like the same name given to different keycodes,
76 * or same keycode given different names, it is resolved according to the
77 * merge mode which applies to the definitions.
79 * The reason for the 4 characters limit is that the name is sometimes
80 * converted to an unsigned long (in a direct mapping), instead of a char
81 * array (see KeyNameToLong, LongToKeyName).
85 * Statements of the form:
86 * alias <MENU> = <COMP>;
88 * Allows to refer to a previously defined key (here <COMP>) by another
89 * name (here <MENU>). Conflicts are handled similarly.
91 * Indicator name statements
92 * -------------------------
93 * Statements of the form:
94 * indicator 1 = "Caps Lock";
95 * indicator 2 = "Num Lock";
96 * indicator 3 = "Scroll Lock";
98 * Assigns a name the indicator (i.e. keyboard LED) with the given index.
99 * The amount of possible indicators is predetermined (XkbNumIndicators).
100 * The indicator may be referred by this name later in the compat section
103 * Effect on the keymap
104 * --------------------
105 * After all of keycodes sections have been compiled, the following members
106 * of struct xkb_keymap are finalized:
107 * xkb_keycode_t min_key_code;
108 * xkb_keycode_t max_key_code;
109 * darray(struct xkb_key_alias) key_aliases;
110 * const char *indicator_names[XkbNumIndicators];
111 * char *keycodes_section_name;
112 * Further, the array of keys:
113 * darray(struct xkb_key) keys;
114 * had been resized to its final size (i.e. all of the xkb_key objects are
115 * referable by their keycode). However the objects themselves do not
116 * contain any useful information besides the key name at this point.
