types: don't use canonical/required types Xkb required every keymap to have at least the four following canonical types: ONE_LEVEL, TWO_LEVEL, ALPHABETIC, KEYPAD. This is specified in e.g. the kbproto spec and XkbKeyTypesForCoreSymbols(3) man page. If these types are not specified in the keymap, the code specifically checks for them and adds them to the 4 first places in the types array, such that they exist in every keymap. These are also the types (along with some non-required 4-level ones) that are automatically assigned to keys which do not explicitly declare a type (see FindAutomaticType in symbols.c, this commit doesn't touch these heuristics, whcih are also not very nice but necessary). The xkeyboard-config does not rely on the builtin xkbcomp definitions of these types and does specify them explicitly, in types/basic and types/numpad, which are virtually always included. This commit removes the special behavior: - The code is ugly and makes keytypes.c harder to read. - The code practically never gets run - everyone who uses xkeyboard-config or a keymap based upon it (i.e. everyone) doesn't need it. So it doesn't get tested. - It mixes policy with implementation for not very good reasons, it seems mostly for default compatibility with X11 core. - And of course we don't need to remain compatible with Xkb ABI neither. Instead, if we read a keymap with no types specified at all, we simply assign all keys a default one-level type (like ONE_LEVEL), and issue plenty of warnings to make it clear (with verbosity >= 3). Note that this default can actually be changed from within the keymap, by writing something like type.modifier = Shift type.whatever_field = value in the top level of the xkb_types section. (This functionality is completely unused as well today, BTW, but makes some sense). This change means that if someone writes a keymap from scratch and doesn't add say ALPHABETIC, then something like <AE11> = { [ q Q ]; }; will ignore the second level. But as stated above this should never happen. Signed-off-by: Ran Benita <ran234@gmail.com>
