58 * The xkb_compat section
59 * =====================
60 * This section is the third to be processed, after xkb_keycodes and
63 * Interpret statements
64 * --------------------
65 * Statements of the form:
66 * interpret Num_Lock+Any { ... }
67 * interpret Shift_Lock+AnyOf(Shift+Lock) { ... }
69 * The xkb_symbols section (see symbols.c) allows the keymap author to do,
70 * among other things, the following for each key:
71 * - Bind an action, like SetMods or LockGroup, to the key. Actions, like
72 * symbols, are specified for each level of each group in the key
74 * - Add a virtual modifier to the key's virtual modifier mapping (vmodmap).
75 * - Specify whether the key should repeat or not.
77 * However, doing this for each key (or level) is tedious and inflexible.
78 * Interpret's are a mechanism to apply these settings to a bunch of
79 * keys/levels at once.
81 * Each interpret specifies a condition by which it attaches to certain
82 * levels. The condition consists of two parts:
83 * - A keysym. If the level has a different (or more than one) keysym, the
84 * match failes. Leaving out the keysym is equivalent to using the
85 * NoSymbol keysym, which always matches successfully.
86 * - A modifier predicate. The predicate consists of a matching operation
87 * and a mask of (real) modifiers. The modifers are matched against the
88 * key's modifier map (modmap). The matching operation can be one of the
90 * + AnyOfOrNone - The modmap must either be empty or include at least
91 * one of the specified modifiers.
92 * + AnyOf - The modmap must include at least one of the specified
94 * + NoneOf - The modmap must not include any of the specified modifiers.
95 * + AllOf - The modmap must include all of the specified modifiers (but
96 * may include others as well).
97 * + Exactly - The modmap must be exactly the same as the specified
99 * Leaving out the predicate is equivalent to usign AnyOfOrNone while
100 * specifying all modifiers. Leaving out just the matching condtition
101 * is equivalent to using Exactly.
102 * An interpret may also include "useModMapMods = level1;" - see below.
104 * If a level fulfils the conditions of several interpret's, only the
105 * most specific one is used:
106 * - A specific keysym will always match before a generic NoSymbol
108 * - If the keysyms are the same, the interpret with the more specific
109 * matching operation is used. The above list is sorted from least to
111 * - If both the keysyms and the matching operations are the same (but the
112 * modifiers are different), the first interpret is used.
114 * As described above, once an interpret "attaches" to a level, it can bind
115 * an action to that level, add one virtual modifier to the key's vmodmap,
116 * or set the key's repeat setting. You should note the following:
117 * - The key repeat is a property of the entire key; it is not level-specific.
118 * In order to avoid confusion, it is only inspected for the first level of
119 * the first group; the interpret's repeat setting is ignored when applied
121 * - If one of the above fields was set directly for a key in xkb_symbols,
122 * the explicit setting takes precedence over the interpret.
124 * The body of the statment may include statements of the following
125 * forms (all of which are optional):
127 * - useModMapMods statement:
128 * useModMapMods = level1;
130 * When set to 'level1', the interpret will only match levels which are
131 * the first level of the first group of the keys. This can be useful in
132 * conjuction with e.g. a virtualModifier statement.
134 * - action statement:
135 * action = LockMods(modifiers=NumLock);
137 * Bind this action to the matching levels.
139 * - virtual modifier statement:
140 * virtualModifier = NumLock;
142 * Add this virtual modifier to the key's vmodmap. The given virtual
143 * modifier must be declared at the top level of the file with a
144 * virtual_modifiers statement, e.g.:
145 * virtual_modifiers NumLock;
147 * - repeat statement:
150 * Set whether the key should repeat or not. Must be a boolean value.
152 * Indicator map statements
153 * ------------------------
154 * Statements of the form:
155 * indicator "Shift Lock" { ... }
157 * This statement specifies the behavior and binding of the indicator
158 * with the given name ("Shift Lock" above). The name should have been
159 * declared previously in the xkb_keycodes section (see Indicator name
160 * statement), and given an index there. If it wasn't, it is created
161 * with the next free index.
162 * The body of the statement describes the conditions of the keyboard
163 * state which will cause the indicator to be lit. It may include the
164 * following statements:
166 * - modifiers statment:
167 * modifiers = ScrollLock;
169 * If the given modifiers are in the required state (see below), the
172 * - whichModifierState statment:
173 * whichModState = Latched + Locked;
175 * Can be any combination of:
176 * base, latched, locked, effective
177 * any (i.e. all of the above)
178 * none (i.e. none of the above)
179 * compat (legacy value, treated as effective)
180 * This will cause the respective portion of the modifer state (see
181 * struct xkb_state) to be matched against the modifiers given in the
182 * "modifiers" statement.
184 * Here's a simple example:
185 * indicator "Num Lock" {
186 * modifiers = NumLock;
187 * whichModState = Locked;
189 * Whenever the NumLock modifier is locked, the Num Lock indicator
193 * groups = All - group1;
195 * If the given groups are in the required state (see below), the led
198 * - whichGroupState statment:
199 * whichGroupState = Effective;
201 * Can be any combination of:
202 * base, latched, locked, effective
203 * any (i.e. all of the above)
204 * none (i.e. none of the above)
205 * This will cause the respective portion of the group state (see
206 * struct xkb_state) to be matched against the groups given in the
207 * "groups" statement.
209 * Note: the above conditions are disjunctive, i.e. if any of them are
210 * satisfied the led is lit.
212 * Virtual modifier statements
213 * ---------------------------
214 * Statements of the form:
215 * virtual_modifiers LControl;
217 * Can appear in the xkb_types, xkb_compat, xkb_symbols sections.
222 * After all of the xkb_compat sections have been compiled, the following
223 * members of struct xkb_keymap are finalized:
224 * darray(struct xkb_sym_interpret) sym_interprets;
225 * darray(struct xkb_indicator_map) indicators;
226 * char *compat_section_name;
227 * TODO: virtual modifiers.
