When reloading, this destroys the old config's swaybg client before
spawning the new config's swaybg. This fixes a race condition where the
old config's swaybg client's destroy was being called after the new
config's swaybg client was being spawned. This was causing the
reference to the new swaybg client to be removed and never destroyed.
This also modifies handle_swaybg_client_destroy to grab the config
reference using wl_container_of on the listener since the swaybg client
may be the old config swaybg client and should be used instead of the
global config instance
In case a set_mode/unset_mode request is sent before the first commit, we need
to handle the value and send our preference accordingly.
This fixes xdg-decoration support for Qt apps.
This clarifies that `workspace <name> output <outputs...>` and
`workspace <name> gaps ...` do not operate on existing workspaces.
Additionally, alternate commands/solutions that operate on existing
workspaces are listed.
This adds support for the following commands for i3 compatibility:
- `move [window|container] [to] output current`
- `move workspace to [output] current`
- `move workspace [to] output current`
The above commands are only useful when used with criteria.
* `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 also refactors our use of gdk-pixbuf a bit, since the only
remaining reverse dependency is swaybar tray support.
When moving a container to become a direct child of the workspace and
the workspace's layout is tabbed or stacked, wrap it in a container
with the same layout. This allows for the following:
- Run `layout tabbed|stacked` on an empty workspace (or use
`workspace_layout tabbed|stacked` in the config)
- Open some views
- Move one of the views in any direction
- Open another view
- The new container should also be `tabbed`/`stacked`
This fixes the criteria for emitting a `bar_state_update` event to
notify swaybar (and any other bars utilizing the event) on whether the
bar is visible by modifier. It is not enough to only emit the event
when both the bar mode and bar hidden state are `hide` since it is
possible to release the modifier while hidden state is `show` and then
change hidden state to `hide` without pressing the modifier. This also
emits the event whenever visible by modifier is set and should no
longer be regardless of the mode and state to ensure that it gets
properly cleared. If visible by modifier is not set and the bar is not
in `hide`/`hide`, then no events will be sent and visible by modifier
will not be set
This modifies cmd_move to allow for the syntax options allowed by i3.
The following syntaxes are supported:
- `move left|right|up|down [<amount> [px]]`
- `move [--no-auto-back-and-forth] [window|container] [to] workspace
<name>|next|prev|next_on_output|prev_on_output|current|number <num>`
- `move [window|container] [to] output <name/id>|left|right|up|down`
- `move [window|container] [to] mark <mark>`
- `move workspace to [output] <name/id>|left|right|up|down`
- `move [window|container] [to] [absolute] position <x> [px] <y> [px]`
- `move [window|container] [to] [absolute] position center`
- `move [window|container] [to] position mouse|cursor|pointer`
This also allows retains the following syntax option that is not
supported by i3, but is supported in sway 1.0:
- `move workspace [to] output <name/id>|left|right|up|down`
The changes are:
- `window` and `container` are now optional
- `output` is now optional for `move workspace` when `to` is given
There is also stricter command checking now. If `absolute` or
`--no-auto-back-and-forth` are given for commands that do not support
them, it will be treated as invalid syntax instead of being silently
ignored.
Disable the i3-compatible behavior if the option '--i3' is not given.
Previously it was only possible to disable it by changing the config
file. Now it also works via swaymsg.
If a client is subscribed and sends a subsequent ipc command which
causes event updates, then those event updates override the
`client->current_command` and send the incorrect type for the payload
associated with the command.
Example:
SUBSCRIBE {window}
RUN_COMMAND focus -> PAYLOAD_TYPE is 0x80000002 for window events
Therefore, we decouple the `client->current_command` by passing it as an
argument to the ipc_send_reply function, avoiding a data race. The same
is done for the `client->payload_length` as a precautionary measure for
the same reason.
Add support for configurations that apply to a type of inputs
(i.e. natural scrolling on all touchpads). A type config is
differentiated by a `type:` prefix followed by the type it
corresponds to.
When new devices appear, the device config is merged on top of its
type config (if it exists). New type configs are applied on top of
existing configs.
Use libinput_device_config_tap_get_finger_count to determine whether
a pointer is a touchpad.
swaymsg is also updated to reflect the new touchpad type.
When setting fullscreen on a hidden scratchpad container, there was a
check to see if there was an existing fullscreen container on the
workspace so it could be fullscreen disabled first. Since the workspace
is NULL, it would cause a SIGSEGV. This adds a NULL check to avoid the
crash.
This also changes the behavior of how fullscreen is handled when adding
a container to the scratchpad or changing visibility of a scratchpad
container to match i3's. The behavior is as follows:
- When adding a container to the scratchpad or hiding a container back
into the scratchpad, there is an implicit fullscreen disable
- When setting fullscreen on a container that is hidden in the
scratchpad, it will be fullscreen when shown (and fullscreen disabled
when hidden as stated above)
- When setting fullscreen global on a container that is hidden in the
scratchpad, it will be shown immediately as fullscreen global. The
container is not moved to a workspace and remains in the
scratchpad. The container will be visible until fullscreen disabled
or killed. Since the container is in the scratchpad, running
`scratchpad show` or `move container to scratchpad` will have no
effect
This also changes `container_replace` to transfer fullscreen and
scratchpad status.
When a tiled window is sent to the scratchpad, we want to use sane
defaults, which is to center it and resize it to the default.
For floating windows, we want to use their existing geometry.
This honors the fullscreen output request for
`xdg_toplevel_set_fullscreen` and `zxdg_toplevel_v6_set_fullscreen`.
If the request was sent before mapping, the fullscreen output request
will be retrieved from the client_pending state for the toplevel. The
output will be passed to `view_map` and if there is a workspace on the
output, the view will be placed on that workspace.
If the request comes in after being mapped, the view will be moved to
the workspace on the output (if there is one) before becoming
fullscreen.
This makes it so there will only be one swaybg instance running
instead of one per output. swaybg's cli has been changed to a xrandr
like interface, where you select an output and then change properties
for that output and then select another output and repeat. This also
makes it so swaybg is only killed and respawned when a background
changes or when reloading.
This fixes a crash for application set idle inhibitors when their
associated view is being destroyed. There is a call to
`view_is_visible` to determine is the view is visible and it assumes
that the view has an container, but it is possible for the container
to already have been destroyed at this point. There is a NULL check for
the view in `check_active` and this re-adds the NULL check for the
container that I accidentally dropped when refactoring during the
inhibit_idle command PR
This fixes a crash in `root_scratchpad_hide` when a layer surface is
focused. Since `seat_get_focus` is NULL when a layer surface is
focused, the call to `node_has_ancestor` was causing a SIGSEGV since it
was attempting to access the parent of NULL. This changes the call to
`seat_get_focus_inactive`, which will return a node even when a layer
surface is focused and is also guaranteed to have something in the
focus stack if a scratchpad container is being hidden (otherwise there
would not be any containers yet).
This matches i3's behavior of setting scratchpad containers to 50% of
the workspace's width and 75% of the workspace's height, bound by the
minimum and maximum floating width/height.
This fixes the sizing of floating non-view containers. On master, the
floater will get set to the maximum width and height, which by default
is the entire output layout. When setting a non-view container to
floating, this will set a sane default size of 50% of the workspace
width and 75% of the workspace height, or whatever the closest is that
the minimum and maximum floating width/height values allow for. On all
future calls to `floating_natural_resize`, the width and height will be
kept unless they need to be changed to respect the min/max floating
width/height values.
This fixes a crash in `container_init_floating` when a xwayland view
sends a configure request while in the scratchpad.
`container_init_floating` gets called so the configured minimum and
maximum sizes gets respected when resizing to the requested size. Since
the workspace was NULL, it would SIGSEGV when attempting to get the
workspace's output for the output box retrieval.
This extracts the resizing portion of `container_init_floating` into a
separate function. If the container is in the scratchpad, it will just
be resized and skip the centering.
Additionally, `container_init_floating` has been renamed to
`container_floating_resize_and_center` to more accurately describe what
it does.
This implements the following command to set/unset a user idle
inhibitor for a view:
`inhibit_idle focus|fullscreen|open|none|visible`
The modes are as follows:
- focus: inhibited when the view is focused by any seat
- fullscreen: inhibited when the view is fullscreen (or a descendant of
a fullscreen container) and is visible on any output
- open: inhibited until the view is closed or the inhibitor is unset or
changed
- none: unsets any user set idle inhibitors for the view
- visible: inhibited when the view is visible on any output
This should have no effect on idle inhibitors set by the applications
themselves and those should still work as intended.
Since this operates on the view in the handler context, it is possible
to set it on the currently focused view, on any existing view with
criteria, or for any future view with for_window.
Removes "unescape_string(argv[i]);".
Since "do_var_replacement(argv[i])" never adds escape
characters, it is both wrong and unnecessary to remove escape characters
on the next line.
This caused characters that were meant to be escaped to not be anymore.
Many laptop screens report unknown subpixel order. Allow users to manually set subpixel hinting to work around this.
Addresses https://github.com/swaywm/sway/issues/3163
This change adds support for renaming a workspace when `exec` command
is being processed by keeping sway_workspace and pid_workspace names in
sync.
The change can be verified by running following command:
swaymsg exec <application>; swaymsg rename workspace number 1 to 5
Fixes: #3952
Since the NOOP output has no size, the minimum floating size is greater
than the workspace size for the NOOP output. In this case, the floater
gets centered in the output instead of the workspace. However, the
NOOP output is not part of the output layout and thus has a NULL box.
Attempting to access the properties of this box was causing a segfault.
This fixes the issue by just setting the floater's box to all zeroes
when mapping on the NOOP output. When the workspace gets moved from the
NOOP output to a new output, any floater whose width or height is zero
or has an x or y location outside of the output, gets passed to
`container_init_floating` again. This will then set the appropriate
size and centering. For any floater that has a valid size and location,
they are preserved.
This fixes the behavior of `__focused__` when there is no focused view
to match i3's behavior of successfully matching no views instead of
returning an error of a missing value. It also applies the same logic
when a token is not applicable (or unset) for a view such as `app_id`
for a focused xwayland view or `class` for a focused xdg-shell view.
This adds an `autofail` boolean to `struct criteria`. If it is set to
`true`, then `criteria_matches_view` will immediately bail out as a
no match. If `autofail` is set, the criteria will also not be
considered empty by `criteria_is_empty`.
To set this new `autofail` property, `get_focused_prop` will now take
in a boolean pointer of the same name. If `__focused__` is supported
for the token and there is no focused view or the focused view does not
have a value for the token, then the boolean will be set to true. In
`parse_token`, the boolean value will be checked and if set to true,
then `criteria->autofail` will be set to true and `parse_token` will
bail successfully. Tokens will still be parsed to make sure the whole
criteria is syntactically valid, which is also why
`&criteria->autofail` is not passed to `get_focused_prop` and a local
boolean is declared in `parse_token`.
This kind of worked before in that focus would change, but it wasn't
intentionally supported and had side effects such as not raising
the container, and being unable to cycle through all floaters depending
on the direction used.
This commit makes it properly supported. The new focus is chosen based
on the distance to the center point of each floating container in the
workspace, and the container is raised.
In a multi output setup, if both visible workspaces have floating
containers, focus will NOT cross into the other output. It is assumed
the user will use a workspace binding in this case.
If two floating containers occupy the exact same center point and you
try to focus in a direction, the behaviour is undefined.
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)
Firstly, this fixes a recent regression where having
`focus_follows_mouse yes` and hovering an inactive tab caused it to gain
focus. The code was missing a view_is_visible check.
The code is handling the logic for both focus_follows_mouse yes and
focus_follows_mouse always, where the latter will apply when nudging the
mouse after a workspace switch. However, the view_is_visible check
didn't apply when using focus_follows_mouse always, so hovering a tab
with that configuration would cause is to focus. This was a bug. When
adding the view_is_visible check, it now applies to both yes and always.
Note that the comment about the split container was wrong. At this point
the hovered node cannot be a split container because it passed the
node_is_view check. The comment has been removed.
Lastly, the else condition is completely removed. This didn't appear to
have any practical use. Setting focus to the result of
seat_get_focus_inactive is very likely going to be a no op. There is a
slim chance that this will break something, and if so I'd like to find
out what so it can be properly documented in the code.
In #3916, I overlooked that `get_output_config` does not handle
wildcards unless the config is reloading, which is a remnant of older
iterations of the output config handling that went unnoticed due to
`output_find_config` handling it. With the current version of the
output config handling, having `get_output_config` handle wildcard
configs is actually preferable. This fixes having only a wildcard
output config in the config file or when connecting/enabling a new
output with only a wildcard config existing.
This introduces a `default` seat operation which is used when no mouse
buttons are being held. This means there is now always a seat operation
in progress. It allows us to separate `default` code from the standard
cursor management code.
The sway_seatop_impl struct has gained callbacks `axis`, `rebase` and
`end`, and lost callbacks `finish` and `abort`. `axis` and `rebase` are
only used by the default seatop. `end` is called when a seatop is being
replaced by another one and allows the seatop to free any resources,
though no seatop currently needs to do this. `finish` is no longer
required, as each seatop can gracefully finish in their `button`
callback. And `abort` is not needed, as calling `end` would achieve the
same thing. The struct has also gained a bool named allow_set_cursor
which allows the client to set a new cursor during `default` and `down`
seatops.
Seatops would previously store which button they were started with and
stop when that button was released. This behaviour is changed so that it
only ends once all buttons are released. So you can start a drag with
$mod+left, then click and hold right, release left and it'll continue
dragging while the right button is held.
The motion callback now accepts dx and dy. Most seatops don't use this
as they store the cursor position when the seatop is started and compare
it with the current cursor position. This approach doesn't make sense
for the default seatop though, hence why dx and dy are needed.
The pressed_buttons array has been moved from the sway_cursor struct to
the default seatop's data. This is only used for the default seatop to
check bindings. The total pressed button count remains in the
sway_cursor struct though, because all the other seatops check it to
know if they should end.
The `down` seatop no longer has a `moved` property. This was used to
track if the cursor moved and to recheck focus_follows_mouse, but seems
to work without it.
The logic for focus_follows_mouse has been refactored. As part of this
I've removed the call to wlr_seat_keyboard_has_grab as we don't appear
to use keyboard grabs.
The functions for handling relative motion, absolute motion and tool
axis have been changed. Previously the handler functions were
handle_cursor_motion, handle_cursor_motion_absolute and
handle_tool_axis. The latter two both called cursor_motion_absolute.
Both handle_cursor_motion and cursor_motion_absolute did very similar
things. These are now simplified into three handlers and a single common
function called cursor_motion. All three handlers call cursor_motion. As
cursor_motion works with relative distances, the absolute and tool axis
handlers convert them to relative first.
This revamps the way that output configs are handled when referencing
an output by both identifier and name. If an output is always referred
to by name or by identifier, this should have no noticeable change. As
soon as there is a name output config and an identifier output config
that matches an output, an output config is generated that is named
`<identifier> on <name>` that is generated with the identifier output
config merged on top of the name output config and stored. When a
change to either is stored, the delta is merged on top of that
"id on name" output config, as well. If the "id on name" output config
exists, it has the highest precedence and will be used when applying
a config to the output.
This fixes the following case:
- `swaymsg output <name> bg /path/to/wallpaper1 fill`
- `swaymsg output <identifier> bg /path/to/wallpaper2 fill`
- `swaymsg output <name> dpms on`
Without this, the wallpaper is changed to `/path/to/wallpaper1`. With
this, the wallpaper remains `/path/to/wallpaper2`.
This removes `output_find_config`, which would take the first matching
output config it found. This is fine if only a name output config,
identifier output config, or even just wildcard exist, but if there is
a name output config and identifier output config, they are not merged.
Instead, this introduces find_output_config, which is just a wrapper
for `get_output_config`. This ensures that both the name and identifier
output configs are respected.
This fixes the following case:
- For simplicity in this example, remove all output configs from config
- Run `swaymsg output <name> bg #ff0000 solid_color`
- Run `swaymsg output <identifier> scale 2`
- Disconnect and reconnect output
Without this, the output will have the background, but not the scale.
With this, the output will have both the background and scale
E.g. `for_window [class="mpv"] move container to output "Dell Inc. ..."`
does not work because the executed move command only uses `Dell` as
output name.
This moves setting `seat->prev_workspace_name` from `workspace_switch`
to `set_workspace`. `workspace_switch` is only called when using a
`workspace` command to change the workspace so any workspace change
based on criteria was not altering `seat->prev_workspace_name`. By
moving it to `set_workspace`, which is called by `seat_set_focus`, it
will change any time focus changes to a node on a different workspace
This makes it so the container gets resized by a configure request for
xwayland floating views. The minimum and maximum sizes are also
respected. Previously, the configure request was resizing the surface
to the size requested, but never changing the container size. This
caused the surface to be rendered outside of the container or to be
smaller than the container. The former is never ideal and the latter
makes no sense for floating views since the container itself can just
be shrunk.
This fixes the decoration rects for floating containers on a workspace
that is either tabbed or stacked. Without this, the floater would
incorrectly try to calculate where it's tab or stack decorations were
on the workspace. This would cause a SIGFPE (due to a divide-by-zero)
when the floater was on a tabbed workspace without any tiling children.
Furthermore, the floater does not care what the workspace's layout is
and should just use the location relative to the workspace. This should
have no effect on children of a floating container.
By the time seatop_allows_events was called, seatop_impl was already
NULL, causing the function to always return false. This means a press
event was sent to clients without a corresponding release event.
This patch moves the call to seatop_finish to after the
seatop_allows_events check.
It turns out sending button events during all seat operations is not
desirable. This patch introduces a new property
`seatop_impl.allows_events` which allows each operation to define
whether button events should be passed to the surface or not.
The `down` seat operation is the only one that supports this. As all the
other seatops don't support it, the calls to seat_pointer_notify_button
prior to starting them have been removed.
Since not all child views's have an unmap event, it is possible for it
to still be mapped (default state) in the destruction handler. When
the destruction handler is called, the corresponding view may have
already been freed and the memory location reallocated. This adds a
listener for the view unmapping and removes the mapped status. This
ensures that the child view is damaged due to destruction while the
view still exists and not after.
If a container gets mapped as fullscreen and set to floating by
criteria, the size and location are never set for the floating
container. This adds a check in container_fullscreen_disable for a
width or height of 0 and calls container_init_floating
This changes `apply_tabbed_layout` and `apply_stacked_layout` to use
`int` instead of `size_t`. This is necessary for tabbed and stacked
containers to be positioned correctly when the y-location is negative.
The reasoning for this is signed plus unsigned is always an unsigned
value. This was causing the y-location of the container to be
positioned near `INT_MIN` due to an unsigned integer underflow
This removes `output_damage_view` since it is unnecessary. The logic
has been moved into its only caller `output_damage_from_view`. When
damaging the whole view, `output_damage_whole_container` should be used
instead
This adds an iterative call in `output_damage_whole_container` to
damage the subsurfaces for all visible views that are inside of the
container. This is needed to damage subsurfaces that extend outside the
box of the container. Without this, those subsurfaces will create
artifacts when moving or resizing.
This adds the device configurations to the ipc response for libinput
devices. Only supported configuration options for the device will be
added. This also moves `libinput_send_events` inside a new `libinput`
object that contains the rest of the configuration options. sway-ipc(7)
has been updated to reflect the changes and document the new additions.
This fixes the deco_rect reported by the ipc for fullscreen containers
to be all zeroes. Children of the fullscreen container should still
have their decorations reported correctly
This fixes the `deco_rect` and `rect` properties in the IPC responses
to match i3's behavior.
`deco_rect` should be relative to the parent node, not the current
node. This also takes tabbed and stacked decorations into account and
will calculate `deco_rect` for all containers since tabbed and stacked
child containers will have decorations.
`rect` should exclude the window decorations.
If two cursor buttons are pressed at the same time, the client will now
be notified of the second button press.
The main reason for not sending the concurrent presses was due to an
early return in dispatch_cursor_button if a seatop is in progress. This
patch makes it call seat_pointer_notify_button prior to returning. But
it also has to make sure there's not a mismatch in events such as a
release without a press.
Prior to this patch, the down seatop would send press and release events
in its begin and finish functions. No other seatops did this. A press
event would be sent prior to starting tiling drag, but never an
associated release.
After this patch, no seatops send their own press or release events. We
send them prior to calling the seatop begin functions, then the first
part of dispatch_cursor_button handles all presses during seatops and
when releasing the seatop.
If a floater is fullscreen either on a workspace or globally, it
should not be rendered on any output is is not fullscreened on. When
rendering it on an output it should not be rendered on, there will be
an extraneous border along the adjacent side of the output. This adds
a check in render_floating to skip all fullscreened floaters
This changes the way zero (which is the default) is interpreted for both
the width and height of `floating_maximum_size`. It now refers to the
width and height of the entire output layout, which matches i3's
behavior.
This also removes duplicated code to calculate the floating constraints
in three files. Before this, `container_init_floating` used two-thirds
of the workspace width/height as the max and the entire workspace
width/height was used everywhere else. Now, all callers use a single
function `floating_calculate_constraints`.
All seat operations except "down" eat the button pressed event and don't send
it to clients. Thus, when ending such seat operations we shouldn't send the
button released event.
This commit moves the logic used to send pressed/released into the "down"
operation.
According to the i3 ipc documentation, `window_rect` excludes the window
decorations from the calculation. This just clarifies that in
`sway-ipc.7.scd`
This add `sway-ipc.7.scd` that documents the IPC protocol.
This also increased the minimum scdoc version from 1.8.1 to 1.9.0 to
allow for table cells to be continued on the following line
`cmd_mode` performs its own quote stripping for the mode string to
avoid double stripping quotes for `cmd_bindcode` and `cmd_bindsym` in
`config_command` and `execute_command`. Stripping quotes in
`execute_command` for `cmd_mode` will also result in double stripping,
which will cause issues for any mode string with spaces, such as pango
markup.
Enables i3-compatible behavior regarding hiding the title bar on tabbed and
stacked containers with one child.
Related issues and merge requests: #3031, #3002, #2912, #2987.
container_floating_move_to_center and container_fullscreen_disable were
calling recursively when the container spawned as a fullscreen floating
container (via for_window). Such a window now doesn't crash sway anymore
but is still configured with a wrong, zero size, making it not directly
usable.
i3 requires all outputs to have certain fields, including 'primary', 'current_workspace', and 'rect' which were missing on disabled outputs.
https://i3wm.org/docs/ipc.html#_outputs_reply
If an unmanaged or layer surface is focused when an output gets
disabled and an empty workspace on the output was focused by the seat,
the seat needs to refocus it's focus inactive to update the value of
`seat->workspace`.
If the noop output is focused (all other outputs disabled/disconnected),
do not auto assign a layer surface to it. The noop output is not enabled
and does not have the `output->layers` list initialized. It also does
not make sense to map the layer surfaces to something that is not
visible.

Fixes#3759
This makes it so running `move [to] scratchpad` on a container already
in the scratchpad does not return an error. To match i3's behavior, a
visible scratchpad container will be hidden and a hidden scratchpad
container will be treated as a noop.
This modifies the places where output_get_active_workspace is called to
handle a NULL result. Some places already handled it and did not need a
change, some just have guard off code blocks, others return errors, and
some have sway_asserts since the case should never happen. A lot of this
is probably just safety precautions since they probably will never be
called when `output_get_active_workspace` is not fully configured with a
workspace.
If an output's node was dirty and the transaction was committed before a
workspace was moved to or created for the output, the instruction would
have a bad value for `state->active_workspace` due to a missing
length check in `output_get_active_workspace`. If there was no focus on
the output, the first workspace was being returned. If the workspace
list was currently empty, the value was either garbage, or in the case of
an output being disabled and re-enabled, a workspace that may have been
previously freed. This just adds the length check to avoid returning out
of bounds value.

This calls `workspace_consider_destroy` on the workspace that was
visible on an output that a workspace was just evacuated to. This
prevents having hidden empty workspaces.
This changes `workspace_next_name` to use the next available number as
the workspace name instead of the number of outputs. This fixes the case
where a number that is already in use could be returned. The workspace
numbers in use have no relation to the number of outputs so it makes
more sense to use the lowest available number
This documents the wildcard character for both inputs and seats. There
is also a tip added on trying the wildcard to verify a setting if the
identifier does not appear to be working.
This fixes the issue of the display freezing on reload with
wlroots#1545.
On master, all output configs are applied on reload. This may cause an
output to have its config applied up to three times, instead of just
once. The three cases are: output name, output identifier, and wildcard.
Not only is this inefficient, but it can cause swaybg to be spawned and
immediately killed.
However, swaybg requires two roundtrips of wl_display (to obtain needed
globals) before it enters its normal event loop. Modesetting will
roundtrip the wl_display. Without modesetting, waitpid for killing
swaybg could block infinitely due to swaybg being blocked by
wl_display_roundtrip.
This only configured an output once. It either uses the wildcard config
or creates an empty wildcard config and applies that. This also fixes a
bug where an output would not be reset when there is no output config to
apply to it.
On the DRM backend, if an output is dpms'd off and a different output is
hotplugged, the CRTC for the output is reclaimed. When modesetting an
output without a CRTC, a CRTC will not be given to an output that is not
desired to be enabled. This splits setting the dpms state in
apply_output_config. If the output should be dpms on, the it is enabled
before attempting to modeset. Otherwise, it is dpms'd off after setting
everything else.
This also adds DPMS_ON to the default output configs.
In seatop_move_tiling, it is possible to cause a stack overflow by
dragging a container into one of its descendants. This disables the
ability to move into a descendant.
This allows the focused inactive tree node and visible workspaces to be
changed while a surface layer has focus. The layer temporarily loses
focus, the tree focus changes, and the layer gets refocused.
When moving a descendant of a tabbed or stacked container, it is possible
for the target node to be the node being moved. This causes a segfault in
`handle_finish` since the node will be detached and then attempted to be
attached to it own parent, which is NULL due to the detach. In this
case, the target node should not be set to the node being moved, but the
parent of the node. This also allows for a descendant of a tabbed or
stacked container to be dragged out of the tabs/stacks and to be a
sibling of the tabbbed/stacked container, which was not previously
possible.
It is possible for `wlr_surface_is_subsurface` to return true, but
`wlr_surface_from_wlr_surface` to be NULL. This adds a NULL check to the
value returned by `wlr_surface_from_wlr_surface` and breaks out of the
while loop in `subsurface_get_root_coords`.
In handle_cursor_motion, the timestamp passed to
`wlr_relative_pointer_manager_v1_send_relative_motion` should be
microseconds (not milliseconds) according to relative-pointer-v1 spec.
When a layer surface is focused, `seat_get_focused_workspace` will be
NULL. This changes `workspace_get_initial_output` to use output of the
focus inactive. If the focus inactive is also NULL, then either the
first output or the noop output will be used as fallbacks.
This aborts sway and displays an error message about XDG_RUNTIME_DIR
not being set without initializing the wl_display or logging any other
information.
This fixes a few misc memory leaks reported by asan:
- Items of `config->config_chain` are now freed instead of just the list
itself
- `bar->swaybar_command` is now freed
- The result returned by a seat subcommand is now returned instead of
leaked
If the active xkb_layout does not have a name, use `NULL` instead of
`json_object_new_string(NULL)`. This also makes it so swaymsg will pretty
print this as `(unnamed)`.
If `repeat_rate` or `repeat_delay` is set without the other being set,
the default was being used for both. This changes the logic to respect
the value given and use the default for the other when only one is set.
If the bar was set to "invisible" and subsequently "toggle" was send twice, the
new mode was never set and the bar->mode was double freed.
Fix this by not requiring the bar->mode to be "hide" and instead show it
unconditionally, because it was either hidden or invisible.
Fixes#3637
It is possible to make the title bars have a zero pixel height while
stacked, by using a blank font and no padding. This causes a division by
zero when attempting to calculate the child index in
container_at_stacked, which then results in a segfault when attempting
to access the child at that bad index (INT_MIN). This just skips the
check to see if the cursor is over a title bar of a child of a stacked
container when the title bar height is zero since there will be no title
bars.
sway-bar(5) documents `modifier none`, which comes from i3. This
implements the functionality for `modifier none` since it was not
previously implemented. The bar modifier toggles visibility of the bar
when the bar mode is set to hide. When the bar modifier is set to
`none`, the ability to toggle visibility of the bar will be disabled.
Since a tablet tool provides the WL_SEAT_CAPABILITY_POINTER capability,
sway will attempt to use the xcursor manager to set a cursor image. If
the tablet tool was the first (and possibly only) device to provide the
capability for the seat, the xcursor manager was not being configured
before attempting to set a cursor image. This was due to
`seat_configure_xcursor` only being called in `seat_configure_pointer`.
Since the xcursor manager was NULL in this case, it would cause a
segfault when attempting to set a cursor image. This adds a call to
`seat_configure_xcursor` in `seat_configure_tablet_tool` to ensure that
the seat has a xcursor manager.
Since `load_include_config` compares against the realpath of a config
file when checking if a config has already been added, the main config's
realpath has to be added to the config_chain.
However, includes from the main config should be processed relative to
the path given to allow for symbolic links. This stores the realpath in
`config->config_chain`, but uses the given path for all other
operations.
When both options and positional arguments are given, sway would print
the error `Don't use options with the IPC client`. Over the past
several months, it seems like users are including this error message in
issues instead of a debug log due to not understanding that the error
message means there is an issue with their command.
This makes the error message more verbose and will hopefully make it so
more users understand that the message is not a bug in sway, but with
the command used.
Since `load_include_config` compares against the realpath of a config
file when checking if a config has already been added, the main config's
realpath has to be added to the config_chain.
wlr_xdg_popup_destroy will destroy popups, so we need to walk the tree
carefully. It's enough to just destroy all direct children, since destroying
the parent will also destroy all children.
If output_cmd_background is given a valid mode as the first argument,
then there is no file given and an error should be returned.
join_args should not be called with an argc of zero since it sets the
last character to the null terminator. With an argc of zero, the length
is zero causing a heap buffer overflow when setting the byte before the
start of argv to '\0'. This probably will not ever generate a segfault,
but may cause data corruption to whatever is directly before it in
memory. To make other such cases easier to detect, this also adds a
sway_assert in join_args when argc is zero.
This fixes a double free in cmd_workspace_gaps when the amount given is
invalid. The end pointer from strtol is part of the argument and should
not be freed. Freeing the end pointer could result in a double free or
bad free depending on whether or not the end pointer was at the start of
the argument
This removes quote stripping for `exec_always` in `execute_command`.
Since `exec_always` commands will be deferred in the config and
processed by `execute_command`, the quotes need to be left intact
like they are for `exec`.
This fixes the failure condition for the wordexp call in
load_include_configs. The only success value is zero. Since the error
codes are positive, having the check be less than zero was causing
segfaults on failure when accessing the words.
If a seat does not exist in seat_cmd_cursor, do not create it. A seat
without any attachments is useless since it will have no capabilities.
This changes `input_manager_get_seat` to have an additional argument
that dictates whether or not to create the seat if it does not exist.
This allows for `-` (hyphen) to be used as an alias for the current seat
while sway is running. This alias was chosen since it is unlikely to
interfere with any desirable seat identifier
This changes the `pointer_constraint` command to be a subcommand of seat
to allow for per-seat settings. The current implementation that is not a
seat subcommand will only operate on the current seat and will segfault
in the config due to `config->handler_context.seat` only being set at
runtime.
This also allows for the wildcard identifier to be used to alter the
pointer constraint settings on all seats and allows for the setting to
be merged with the rest of the seat config.
Updates sway.5 to include information on the usage of the `--whole-window` option in the context of the `bindsym` command, which modifies mouse bindings to allow them to operate over the whole window instead of just the titlebar. Also includes the disclaimer about mouse bindings only working over the title bar.
Also fixes the escaping of the `BTN_LEFT` and `BTN_RIGHT` key mention.
Add notes on --border and --exclude-titlebar
Update the flags for bindcode command.
This cleans up the log when sway fails to read a config file. The
following changes have been made:
- A missing error message has been added to the log when the config file
is a directory instead of a regular file
- In main, `goto` statements have been added after the `sway_terminate`
calls instead of wrapping every block in `if (!terminate_request)`
- Unnecessary NULL-checks around calls to free in `main` have been
removed
- Deferred command execution has been extracted to a separate function
and the `Running deferred commands` log message will not be shown when
there are no deferred commands.
Add a sentence to sway-output.5.scd to highlight that the cursor can
only be moved between immediately adjacent outputs.

Fixes#3311
Just a convenience function that improves readability of the code.
Other things worth noting:
* container_get_siblings and container_sibling_index no longer use the
const keyword
* container_handle_fullscreen_reparent is only ever called after
attaching the container to a workspace, so its con->workspace check has
been changed to an assertion
The goal here is to center fullscreen views when they are both too small
for the output and refuse to resize to the output's dimensions. It has
the side effect of also centering the view when it's too small for its
container.
Example clients that have this behaviour are emersion's hello-wayland
and weston.
It works by introducing surface_{x,y,width,height} properties to the
container struct. The x and y represent layout-local coordinates where
the surface will be rendered. The width and height are only used to
track the surface's previous dimensions so we can detect when the client
has resized it and recenter and apply damage accordingly.
The new surface properties are calculated when a transaction is applied,
as well as when a view resizes itself unexpectedly. The latter is done
in view_update_size. This function was previously restricted to views
which are floating, but can now be called for any views.
For views which refuse to resize *smaller* than a particular size, such
as gnome-calculator, the surface is still anchored to the top left as
per the current behaviour.
In addition to removing unused code, two minor problems are fixed:
(1) `resize set` and `resize adjust` did not error when given
too many arguments.
(2) `orientation` was incorrectly overridden to be 'U' for
scroll events in the swaybar tray `handle_click` function.
This removes the call to `root_scratchpad_show` from
`root_scratchpad_remove_container` and places it in the
`cmd_move_container`. This also moved the IPC `window::move` event to
`cmd_scratchpad`.
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.
This add errors from calls to `libinput_device_config_*_set` to the
debug log. This may be useful when looking at issues related to input
devices and config settings not working.
This extends `input <identifier> events toggle` to allow for an optional
list of modes to toggle through. If no event modes are listed, all
supported modes are cycled through (current behavior). If event modes
are listed, they will be cycled through, defaulting to the first mode
listed when the current mode is not in the list. This modes listed will
also not be checked to see if the device supports them and may fail.
If output->configured is true, then the output has been modeset correctly and
we don't need to try again. If output->enabled is true, then we are in the
process of configuring the output and we shouldn't do anything.
Designing the output configuration sequence without invalid state is tricky.
We have one function, apply_output_config, that takes an output and (besides
other things) performs a modeset and inserts the output in the output layout.
The modeset can fail, in which case we don't want the output to be enabled.
We also have an output_enable function, which calls output_apply_config and
also configures the output's workspace and inserts it in the root container.
Now, we have two choices.
Either we configure the output before it's been inserted in the root container
and then, if the modeset was successful, we insert it and create the workspace.
The main issue with this approach is that configuring the output triggers a
handful of signals, namely wlr_output.mode and wlr_output_layout.change. In
those event handlers, we need to make sure to ignore these outputs in the
process of being configured.
Either we first insert the output, create the workspace and then try to
configure it. It means we need to undo everything if the modeset fails. The
main issue with this solution is that it enables and disables the output very
quickly, creates a workspace and immediately destroys it, and maybe moves
views back and forth (see output_evacuate).
I've tried to make it so an output isn't enabled then immediately disabled. We
already have code for ignoring outputs when the output is being destructed.
Fixes https://github.com/swaywm/sway/issues/3462
This happens if you plug in more outputs than supported by your GPU.
This patch makes it so outputs without CRTCs appear as disabled. As soon as
they get a CRTC (signalled via the mode event), we can enable them.
This modifies `bar_cmd_tray_bindsym` to use `get_mouse_bindsym` for
parsing mouse buttons. This also introduces `bar_cmd_tray_bindcode`,
which will use `get_mouse_bindcode` for parsing mouse buttons. Like with
sway bindings, the two commands are encapsulated in a single file to
maximize shared code.
This also modifies tray bindings to work off of events codes rather than
x11 buttons, which allows for any mouse buttons to be used.
For `get_bar_config`, `event_code` has been added to the `tray_bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
In `sway_terminate`, `ipc_event_shutdown` was being sent regardless
which mode sway was running in. When running as an ipc client,
`sway_terminate` should just exit
Clear the focus when we hide the cursor and show it again during the unhide
action. The unhide function will rebase the cursor after the unhide.
Tested by looking at the WAYLAND_DEBUG=1 output of termite.
Also call cursor_handle_activity before sending pointer events to send the enter
events to the surface if the cursor was hidden before.
Fixes#3431
This fixes the handling of hidden scratchpad containers for some
commands. For the most part, this just prevents running the commands on
hidden scratchpad containers, but there are some commands that have some
special handling for them.
For example, create layout V[view view view] and resize the leftmost
view using mod+rightclick. Previously, the edge between view 2 and 3
would be adjusted as well. Now this edge will remain constant, which
matches the behaviour of i3.
To do this operation correctly, the resize tiling seatop now keeps track
of two containers, as the container that resizes horizontally will be a
different container to the one which resizes vertically (one will be an
ancestor). The tiling resize seatop now figures out these containers
during the start of the operation and keeps references to them in the
event. A new function container_find_resize_parent has been introduced
to do this. This function is also used by the resize command.
During cursor motion, the seatop logic is similar to before, but now has
to choose the correct container to resize.
In resize.c, container_resize_tiled and resize_tiled have been merged
into one. One of them originally did nothing except pass the values
through to the other.
container_resize_tiled now takes a simplified approach where it just
finds the immediate siblings on either side and resizes them without
worrying about the others. The parellel_coord and parallel_size
functions are no longer needed and have been removed.
When resetting the keyboard during reload, disarm the key repeat on all
keyboards since the bindings (and possibly keyboard) will be freed before
the key repeat can go off.
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 field is not in i3 and provides imprecise and redundant information.
(Specifically, when swaymsg is given a list of commands, the IPC return
array already indicates precisely which number command failed; knowing
the name of the command is not useful when multiple commands of the
same type are provided.)
This patch removes the resize_axis enum in favour of wlr_edges. As
wlr_edges has no `horizontal` or `vertical` value, it denotes these by
bitwise `or`ing the left/right and up/down values. Two constants are
defined to make it easier to refer to these.
This will allow the tiling resize seatop to utilise the functions in
this file. resize_axis was local to the resize command and couldn't be
exposed in function arguments.
When the config has continued lines, `get_line_with_cont` may read more
than one line of the actual file. When displaying line numbers for error
messages, they should be the line number in the file to make it easy to
find and fix the issue.
Adds the bar subcommand `status_padding <padding>` which allows setting
the padding used for swaybar. If `status_padding` is set to `0`, blocks
will be able to take up the full height of the bar.
This modifies `input_cmd_scroll_button` to utilize the mouse button
helper `get_mouse_button` when parsing the button. x11 axis buttons are
not supported with this command and `CMD_INVALID` will be returned, but
all other x11 buttons, button event names, and button event codes should
be working
This modifies `bar_cmd_bindsym` to use `get_mouse_bindsym` for parsing
mouse buttons. This also introduces `cmd_bar_bindcode`, which will use
`get_mouse_bindcode` for parsing mouse buttons. Like sway bindings, the
two commands are encapsulated in a single file with shared code.
This also modifies swaybar to operate off of event codes rather than x11
button numbers, which allows for any mouse button to be used.
This introduces two new IPC properties:
- For `get_bar_config`, `event_code` has been added to the `bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
- Likewise for `click_events`, `event` has been added and will include
the event code for the button clicked. If the event code can be mapped
to a x11 button, `button` will still be the x11 button number.
Otherwise, `button` will be `0`.
This modifies `seat_cmd_cursor` to utilize `get_mouse_button` when
parsing mouse buttons for the `press` and `release` operations. All x11
buttons, button event names, and button event codes are supported.
For x11 axis buttons, `dispatch_cursor_axis` is used instead of
`dispatch_cursor_button`. However the `press`/`release` state is ignored
and the either axis event is processed. This also removes support for
`left` and `right` in favor of `BTN_LEFT` and `BTN_RIGHT`.
This splits each seat operation (drag/move tiling/floating etc) into a
separate file and introduces a struct sway_seatop_impl to abstract the
operation.
The move_tiling_threshold operation has been merged into move_tiling.
The main logic for each operation is untouched aside from variable
renames.
The following previously-static functions have been made public:
* node_at_coords
* container_raise_floating
* render_rect
* premultiply_alpha
* scale_box
This fixes two causes of segfaulting when an output is destroyed.
The first occurred when an output was never enabled. The issue was that
the destroy signal was never initialized so when it was emitted, sway
segfaulted. This was fixed by moving the initialization into
`output_create` since all outputs, regardless of whether they have ever
been enabled, will be destroyed at some point.
The second occurred when the cursor was on an output that was being
destroyed. The sway output would have already been removed, but if there
are other outputs, a cursor rebase would still occur. Since the
wlr_output still existed and the sway output was destroyed, the cursor
could be over nothing, resulting in a segfault when trying to get the
sway output, which was destroyed.
Implements toggling input events during runtime. This will not attempt
to toggle to a mode that is not supported by the device.
When toggling the wildcard input, the device specific input configs are
altered. Each device will cycle one supported mode.
This allows tabbed and stacked containers to be scrolled through when
the cursor is over the border of the title bar. The borders around the
other three edges of the contents should not be affected by this change.
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.
The following helper functions have been added to aid with parsing mouse
buttons from a string:
1. `get_mouse_bindsym`: attempts to parse the string as an x11 button
(button[1-9]) or as an event name (ex BTN_LEFT or BTN_SIDE)
2. `get_mouse_bindcode`: attempts to parse the string as an event code
and validates that the event code is a button (starts with `BTN_`).
3. `get_mouse_button`: this is a conveniency function for callers that
do not care whether a bindsym or bindcode are used and attempts to parse
the string as a bindsym and then bindcode.
None of these functions are used in this commit. The sole purpose of
this commit is to make the larger set more granular and easier to
review/manipulate. There will be a series of commits following this one
that will modify any command which uses a mouse button to use these
helpers.
