Jasper St. Pierre 4fb7b06b 2014-02-21T18:09:00 state: Add xkb_state_key_get_consumed_mods This retrieves the mask of consumed modifiers for a given key and state, which is helpful for toolkits without having them to do it one modifier at a time, or pass in 0xFFFFFFFF to xkb_state_remove_consumed_mods to "reverse-engineer" the consumed mods.
Ran Benita 973b8fd4 2014-02-08T16:40:20 api: deprecate XKB_MAP_COMPILE_PLACEHOLDER, and use KEYMAP instead of MAP The PLACEHOLDER was not meant to be used, but c++ doesn't like passing 0 to enums, so it was used. For this reason we add all the NO_FLAGS items, so the PLACEHOLDER shouldn't be used anymore. Second, XKB_MAP is the prefix we used ages ago, KEYMAP is the expected prefix here. So deprecate that as well. The old names may still be used through the xkbcommon-compat.h header, which is included by default (no need to include directly).

Ran Benita eb348255 2013-07-20T23:21:44 x11: add XKB protocol keymap and state creation support These are function to create an xkb_keymap directly from XKB requests to the X server. This opens up the possibility for X clients to use xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for keyboard support. The X11 support must be enabled with --enable-x11 for now. The functions are in xkbcommon/xkbcommon-x11.h. It depends on a recent libxcb with xkb enabled. The functions are in a new libxkbcommon-x11.so, with a new pkg-config file, etc. so that the packages may be split, and libxkbcommon.so itself remains dependency-free. Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES property? This does not account for custom keymaps, on-the-fly keymap modifications, remote clients, etc., so is not a proper solution in practice. Also, some servers don't even set it. Now, the client just needs to recreate the keymap in response to a change in the server's keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends).

Wander Lairson Costa ac59e735 2013-09-26T09:35:33 Make C++ happy. For most functions taking an enum flags parameter, we use 0 value to indicate that no flags should be applied. C++ has a stronger type system than C and will not implicitly convert int's to enum's. Thus, we create valid 0 enum values for enum types where it makes sense.

Ran Benita 2a2a8d7d 2013-08-13T18:57:43 state: apply capitalization transformation on keysyms The xkbproto spec says: http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier If the Lock modifier is not consumed by the symbol lookup process, routines that determine the symbol and string that correspond to an event should capitalize the result. This was not an issue until now, because most xkeyboard-config keymaps do not utilize this "feature", and specify the keysyms for the Lock modifier explicitly instead. However, some keymaps do depend on it, e.g. ch(fr) for eacute and others. The spec goes on to describe two options for doing this transformation: locale-sensitive and locale-insensitive. We opt for the latter; it is less desirable but we don't want *that* headache. Also, only xkb_state_key_get_one_sym() is changed; xkb_state_key_get_syms() is left as-is, and always reports the untransformed keysyms. This is for the following reasons: - The API doesn't allow it, since we return a const pointer directly to the keymap keysyms table and we can't transform that. - The transformation doesn't make sense for multiple-keysyms. - It can be useful for an application to get the "raw" keysyms if it wants to (e.g. maybe it wants to do the transformation itself). Finally, note that xkb_state_mod_index_is_consumed() does *not* report Lock as consumed even if it was used in the transformation. This is what Xlib does. This definitely doesn't fall under the "hard to misuse" API rule but it's the best we can do. https://bugs.freedesktop.org/show_bug.cgi?id=67167 Reported-By: Gatis Paeglis <gatis.paeglis@digia.com> Signed-off-by: Ran Benita <ran234@gmail.com>

David Herrmann 36f55c49 2013-03-11T12:53:39 keymap: add xkb_keymap_new_from_buffer() The current API doesn't allow the caller to create keymaps from mmap()'ed files. The problem is, xkb_keymap_new_from_string() requires a terminating 0 byte. However, there is no way to guarantee that when using mmap() so a user currently has to copy the whole file just to get the terminating zero byte (assuming they cannot use xkb_keymap_new_from_file()). This adds a new entry xkb_keymap_new_from_buffer() which takes a memory location and the buffer size in bytes. Internally, we depend on yy_scan_{string,byte}() helpers. According to flex documentation these already copy the input string because they are wrappers around yy_scan_buffer(). yy_scan_buffer() on the other hand has some insane requirements. The buffer must be writeable and the last two bytes must be ASCII-NUL. But the buffer may contain other 0 bytes just fine. Because we don't want these constraints in our public API, xkb_keymap_new_from_buffer() needs to create a copy of the input memory. But it then calls yy_scan_buffer() directly. Hence, we have the same number of buffer-copies as with *_from_string() but without the terminating 0 requirement. The explicit yy_scan_buffer() call is preferred over yy_scan_byte() so the buffer-copy operation is not hidden somewhere in flex. Maybe some day we no longer depend on flex and can have a zero-copy API. A user could mmap() a file and it would get parsed right from this buffer. But until then, we shouldn't expose this limitation in the API but instead provide an API that some day can work with zero-copy.

Ran Benita 60bd9202 2012-11-11T00:22:46 keymap: wrap the layout parameter if it is out of range for the key The functions num_levels_for_key() and get_syms_by_level() have a 'layout' parameter. Currently it is expected that this value is always legal for the key, as determined by num_layouts_for_key(). However, there are legitimate use cases for passing an out-of-range layout there, most probably passing the effective layout, and expecting to get the keysyms/levels for just this layout. So we wrap it just as we do in the xkb_state_* functions. This is also useful for stuff like this: http://developer.gnome.org/gdk/stable/gdk-Keyboard-Handling.html#gdk-keymap-lookup-key If this behavior is not desired, the user has the option to check against num_layouts_for_key herself. https://bugs.freedesktop.org/show_bug.cgi?id=56866 Reported-by: Gatis Paeglis <gatis.paeglis@digia.com> Signed-off-by: Ran Benita <ran234@gmail.com>

Ran Benita 4b81c9f3 2012-10-22T21:00:57 Report which components of the state have changed We add a return value to the xkb_state_update_key and xkb_state_update_mask, which reports to the caller which of the state components have changed as a result. This restores the XKB functionality of the XkbStateNotify and XkbIndicatorsStateNotify events. See: http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Events It is quite useful in some situations. For example, it allows an application to avoid doing some work if nothing of relevance in the state has changed. Say, a keyboard layout applet. Also useful for debugging. The deltas themselves are not provided, because I can't see a use case. If needed, it should be possible to add some API for that. In xkbcommon, keymaps are immutable, so all of the other *Notify events from XKB are irrelevant. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 6a94b122 2012-10-22T20:49:44 Split the mods, layout, leds parts of xkb_state_components Note first: This commits breaks the ABI somewhat. If an application is run against this commit without recompiling against the updated header, these break: - xkb_state_layout_*_is_active always retuns false. - xkb_state_serialize_mods always returns 0. So it might break layout switching in some applications. However, xkbcommon-compat.h provides the necessary fixes, so recompiling should work (though updating the application is even better). Split the enum to its individual components, which enables us to refer to them individually. We will use that later for reporting which components of the state have changed after update.

David Herrmann 7b3bd11f 2012-10-16T16:05:34 Add xkb_keysym_from_name() flags argument for case-insensitive search This adds a flags argument to xkb_keysym_from_name() so we can perform a case-insensitive search. This should really be supported as many keysyms have really weird capitalization-rules. However, as this may produce conflicts, users must be warned to only use this for fallback paths or error-recovery. This is also the reason why the internal XKB parsers still use the case-sensitive search. This also adds some test-cases so the expected results are really produced. The binary-size does _not_ change with this patch. However, case-sensitive search may be slightly slower with this patch. But this is barely measurable.

Ran Benita bbf388ec 2012-10-11T16:54:17 Make xkb_keymap_num_leds return the index range instead of active count Currently xkb_keymap_num_leds() returns a count of valid (settable) leds. Because the indexes might be non-consecutive, and some leds might not be settable, it is incorrect to use this function for iterating over the leds in the keymap. But this is the main use case of this function, so instead of the current behavior we adapt the function to the use case by making it return the needed range of iteration. The caller needs to handle invalid intermittent indexes, though. Signed-off-by: Ran Benita <ran234@gmail.com>

Ran Benita 9a18b872 2012-09-23T17:52:51 Add format argument to xkb_keymap_get_as_string This function really needs a format argument, for symmetry with the keymap creation functions. If we add new formats, we will almost certainly want to add support for serializing it into a string. It would also allow to convert from one format to another, etc. The in the common case, the user would just want to use the format she used to create the keymap; for that we add a special XKB_KEYMAP_USE_ORIGINAL_FORMAT value, which will do that (it is defined to -1 outside of the enum because I have a feeling we might want to use 0 for something else). To support this we need to keep the format inside the keymap. While we're at it we also initialize keymap flags properly. This changes the API, but the old xkb_map_get_as_string name works as expected so this is the best time to do this. Signed-off-by: Ran Benita <ran234@gmail.com>

Ran Benita 1a930bf2 2012-08-07T00:20:40 Add API to query whether a modifier is consumed Currently the user has no way of knowing which of the active modifiers have been used in the translation of a keycode to its keysyms. The use case is described in the GTK docs: say there's a menu accelerator activated by "<Alt>+". Some layouts have "+" shifted, and some have it on the first level. So in keymaps where "+" is shifted, the Shift modifier is consumed and must be ignored when the user is testing for "<Alt>+". Otherwise, we may get "<Alt><Shift>+" and the accelerator should not actually fire. For this we also use the preserve[] information in the key types, which can forces us to report modifiers as unconsumed even if they were used in the translation. Until now we didn't do anything with this information. The API tries to match its surronding. It's not very efficient but this can be fixed. Signed-off-by: Ran Benita <ran234@gmail.com>

Ran Benita 70f35cfb 2012-07-20T13:10:13 Add logging API Add new public API to provide the library users with some options to control and customize the logging output from the library. It is based upon the skeleton from the libabc demo libray: https://git.kernel.org/?p=linux/kernel/git/kay/libabc.git which is public domain and works pretty well. This requires passing in the context object in every logging call, and thus the conversion is done file by file. We also remove the global warningLevel variable in favor of a verbosity level in the context, which can be set by the user and is silent by default. One issue is the ACTION calls, which, while nice, do not play very well with line- and priority-based logging, and would require some line continuation handling or keeping state or some other compromise. So instead remove these and just inline them with their respective warning/error. So instead of: ERROR("Memory allocation failed\n") ACTION("Removing all files on hardisk\n") its something like that: log_err("Memory allocation failed; Removing all files on harddisk\n") Signed-off-by: Ran Benita <ran234@gmail.com>
