There is no need to check for transactions at the end of every user
input, as the vast majority of input will not issue transactions. This
implementation can also hide where changes are made without an
appropriate transaction commit, as a future unrelated input would issue
the commit instead.
Instead, commit transactions in places where changes are made or are
likely to be made.
This allows e.g. triggering one command while a key is held, then
triggering another to undo the change performed by it afterwards. One
use case for this is triggering push-to-talk functionality for VoIP
tools without granting them full access to all input events.
Fixes#3151
Adding support for the keyboard shortcuts inhibit protocol allows remote
desktop and virtualisation software to receive all keyboard input in
order to pass it through to their clients so users can fully interact
the their remote/virtual session. The software usually provides its own
key combination to release its "grab" to all keyboard input. The
inhibitor can be deactivated by the user by removing focus from the
surface using another input device such as the pointer.
Use support for the procotol in wlroots to add support to sway. Extend
the input manager with handlers for inhibitor creation and destruction
and appropriate bookkeeping. Attach the inhibitors to the seats they
apply to to avoid having to search the list of all currently existing
inhibitors on every keystroke and passing the inhibitor manager around.
Add a helper function to retrieve the inhibitor applying to the
currently focused surface of a seat, if one exists.
Extend bindsym with a flag for bindings that should be processed even if
an inhibitor is active. Conversely this disables all normal shortcuts if
an inhibitor is found for the currently focused surface in
keyboard::handle_key_event() since they don't have that flag set. Use
above helper function to determine if an inhibitor exists for the
surface that would eventually receive input.

This adds support for specifying a binding for a specific group. Any
binding without a group listed will be available in all groups. The
priority for matching bindings is as follows: input device, group, and
locked state.
For full compatibility with i3, this also adds Mode_switch as an alias
for Group2. Since i3 only supports this for backwards compatibility
with older versions of i3, it is implemented here, but not documented.
This adds a --reload flag to cmd_bindswitch that allows for the binding
to be executed on reload. One possible use case for this is to allow
users to disable outputs when the lid closes and enable them when the
lid opens without having to open and re-close the lid after a reload.
This adds the logic to defer binding execution while sway is still
initializing. Without this, the binding command would be executed, but
the command handler would return CMD_DEFER, which was being treated as
a failure to run. To avoid partial executions, this will defer all
bindings while config->active is false.
This changes the behavior of bindings to make the `BINDING_LOCKED` flag
conflicting, which will allow for both unlocked and locked bindings.
If there are two matching bindings and one has `--locked` and the other
does not, the one with `--locked` will be preferred when locked and
the one without will be preferred when unlocked.
If there are two matching bindings and one has both a matching
`--input-device=<input>` and `--locked` and the other has neither, the
former will be preferred for both unlocked and locked.
This also refactors `get_active_binding` in `sway/input/keyboard.c`
to make it easier to read.
* `bindsym --to-code` enables keysym to keycode translation.
* If there are no `xkb_layout` commands in the config file, the translation
uses the XKB_DEFAULT_LAYOUT value.
* It there is one or more `xkb_layout` command, the translation uses
the first one.
* If the translation is unsuccessful, a message is logged and the binding
is stored as BINDING_KEYSYM.
* The binding keysyms are stored and re-translated when a change in the input
configuration may affect the translated bindings.
This commit adds support for laptop lid and tablet
mode switches as provided by evdev/libinput and
handled by wlroots.
Adds a new bindswitch command with syntax:
bindswitch <switch>:<state> <command>
Where <switch> is one of:
tablet for WLR_SWITCH_TYPE_TABLET_MODE
lid for WLR_SWITCH_TYPE_LID
<state> is one of:
on for WLR_SWITCH_STATE_ON
off for WLR_SWITCH_STATE_OFF
toggle for WLR_SWITCH_STATE_TOGGLE
(Note that WLR_SWITCH_STATE_TOGGLE doesn't map to
libinput and will trigger at both on and off events)
Modifier handling functions were moved into sway/input/keyboard.c;
opposite_direction for enum wlr_direction into sway/tree/output.c;
and get_parent_pid into sway/tree/root.c .
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
Patch tested by compiling with `__attribute__ ((format (printf, 2, 3)))`
applied to `cmd_results_new`.
String usage constants have been converted from pointers to arrays when
encountered. General handler format strings were sometimes modified to
include the old input string, especially for unknown command errors.
This modifies `bindcode` and `bindsym` to use `get_mouse_bindcode` and
`get_mouse_bindsym`, respectively, to parse mouse buttons. Additionally,
the `BINDING_MOUSE` type has been split into `BINDING_MOUSECODE` and
`BINDING_MOUSESYM` to match keys and allow for mouse bindcodes to be
used. Between the two commands, all button syms and codes should be
supported, including x11 axis buttons.
evdev-proto is installed by a dependency, so some files have been missed:
In file included from ../sway/input/cursor.c:3:
/usr/local/include/libevdev-1.0/libevdev/libevdev.h:30:10: fatal error: 'linux/input.h' file not found
#include <linux/input.h>

`seat_execute_command` was incorrectly setting
`config->handler_context.seat` before calling `execute_command`. Since
`execute_command` was being called with a `NULL` seat argument,
`execute_command` was setting `config->handler_context.seat` to the
default seat. This resulted in all bindings being executed on the
default seat and causing undesired behavior for devices on other seats.
This modifies the way mouse bindings are parsed. Instead of adding to
BTN_LEFT, which results in button numbers that may not be expected,
buttons will be parsed in one of the following ways:
1. `button[1-9]` will now map to their x11 equivalents. This is already
the case for bar bindings. This adds support for binding to axis events,
which was not possible in the previous approach.
2. Anything that starts with `BTN_` will be parsed as an event code name
using `libevdev_event_code_from_name`. This allows for any button to be
mapped to instead of limiting usage to the ones near BTN_LEFT. This also
adds a dependency on libevdev, but since libevdev is already a dependency
of libinput, this should be fine. If needed, this option can have dependency
guards added.
Binding changes:
- button1: BTN_LEFT -> BTN_LEFT
- button2: BTN_RIGHT -> BTN_MIDDLE
- button3: BTN_MIDDLE -> BTN_RIGHT
- button4: BTN_SIDE -> SWAY_SCROLL_UP
- button5: BTN_EXTRA -> SWAY_SCROLL_DOWN
- button6: BTN_FORWARD -> SWAY_SCROLL_LEFT
- button7: BTN_BACK -> SWAY_SCROLL_RIGHT
- button8: BTN_TASK -> BTN_SIDE
- button9: BTN_JOYSTICK -> BTN_EXTRA
Since the axis events need to be mapped to an event code, this uses the
following mappings to avoid any conflicts:
- SWAY_SCROLL_UP: KEY_MAX + 1
- SWAY_SCROLL_DOWN: KEY_MAX + 2
- SWAY_SCROLL_LEFT: KEY_MAX + 3
- SWAY_SCROLL_RIGHT: KEY_MAX + 4
Adds the function `config_add_swaynag_warning(char *fmt, ...)` so that
handlers can add warnings to the swaynag config log in a uniform way.
The formatting is identical to errors and include the line number, line,
and config path.
This also alters the background file access warning to use the function
and introduces a warning for duplicate bindings.
This matches i3's behavior of returning a list of results that contain
the result of each command that was executed. Additionally, the
`parse_error` attribute has been added to the IPC JSON reply.
This patch makes it so when you run reload, the actual reloading is
deferred to the next time the event loop becomes idle. This avoids
several use-after-frees and removes the workarounds we have to avoid
them.
When you run reload, we validate the config before creating the idle
event. This is so the reload command will still return an error if there
are validation errors. To allow this, load_main_config has been adjusted
so it doesn't apply the config if validating is true rather than
applying it unconditionally.
This also fixes a memory leak in the reload command where if the config
failed to load, the bar_ids list would not be freed.
This adds a `con` argument to `execute_command` which allows you to
specify the container to execute the command on. In most cases it leaves
it as `NULL` which makes it use the focused node. We only set it when
executing `for_window` criteria such as when a view maps. This means we
don't send unnecessary IPC focus events, and fixes a crash when the
criteria command is `move scratchpad` (because we can't give focus to a
hidden scratchpad container).
Each of the shell map handlers now check to see if the view has a
workspace. It won't have a workspace if criteria has moved it to the
scratchpad.
seat_execute_command needs to check the flags on `binding_copy`, as
`binding` will be a dangling pointer after a reload command.
handle_keyboard_key needs to set the next_repeat_binding for
non-reloads prior to executing the command in case the binding is
freed by the reload command.
Fixes#2568
The binding that gets stored in the keyboard's `repeat_binding` would
get freed on reload, leaving a dangling pointer.
Rather than attempt to unset the keyboard's `repeat_binding` along with
the other bindings, I opted to just not set it for the reload command
because there's no point in reloading repeatedly by holding the binding.
This disables repeat bindings for the reload command.
As we now need to detect whether it's a reload command in two places,
I've added a binding flag to track whether it's a reload or not.
If sway is reloaded using a bindsym which has multiple commands, it
failed to detect the reload command, didn't create a duplicate of the
binding and would crash because the reload command frees the bindings.
For example:
mode system {
bindsym r reload, mode default
}
In this example, the binding->command is "reload, mode default".
Fixes#2545
The mouse binding logic is inspired/copied from the
keyboard binding logic; we store a sorted list of the
currently pressed buttons, and trigger a binding when
the currently pressed (or just recently pressed, in
the case of a release binding) buttons, as well as
modifiers/container region, match those of a given
binding.
As the code to execute a binding is not very keyboard
specific, keyboard_execute_command is renamed to
seat_execute_command and moved to where the other
binding handling functions are. The call to
transaction_commit_dirty has been lifted out.
First, the existing sway_binding structure is given an
enumerated type code. As all flags to bindsym/bindcode
are boolean, a single uint32 is used to hold all flags.
The _BORDER, _CONTENTS, _TITLEBAR flags, when active,
indicate in which part of a container the binding can
trigger; to localize complexity, they do not overlap
with the command line arguments, which center around
_TITLEBAR being set by default.
The keyboard handling code is adjusted for this change,
as is binding_key_compare; note that BINDING_LOCKED
is *not* part of the key portion of the binding.
Next, list of mouse bindings is introduced and cleaned up.
Finally, the binding command parsing code is extended
to handle the case where bindsym is used to describe
a mouse binding rather than a keysym binding; the
difference between the two may be detected as late as
when the first key/button is parsed, or as early as
the first flag. As bindings can have multiple
keycodes/keysyms/buttons, mixed keysym/button sequences
are prohibited.
Sort the list comprising the set of keys for the binding in ascending
order. (Keyboard shortcuts depend only on the set of simultaneously
pressed keys, not their order, so this change should have no external
effect.) This simplifies comparisons between bindings.
