Some examples use comma to separate x and y for setting the output
position which is wrong.
Let's change it to spaces, as correctly demonstrated in the
`output <name> position|pos <X> <Y>` section.
Popups are positioned relative to local surface coordinates of the
parent surface. There's no need to consider values set with
xdg_surface.set_window_geometry for parent surfaces.
Sometimes when using direct scan-out, some flickering between the
fullscreen app and the regular desktop could be seen.
This happened because we called wlr_output_attach_render and then
wlr_output_attach_buffer for direct scan-out. wlr_output_attach_render
makes the OpenGL context current but also attaches the OpenGL buffer to
the primary plane apparently (all of this happens inside
eglMakeCurrent).
This patch moves the scan-out logic outside of output_render, before
wlr_output_attach_render. This lines it up with rootston's
implementation. This also makes more sense since no rendering is
involved when using direct scan-out.
Sorry about that, I should've tested this with more clients. The new
code has been tested with mpv and a GLFW demo.
Sway has basic support for drawing tablets, but does not expose
properties such as pressure sensitivity. This implements the wlr tablet
v2 protocol, providing tablet events to Wayland clients.
If the view was mapped as fullscreen or the view was assigned either a
workspace or output, the pid was not being populated since it was
occurring as part of the pid mapping check in select_workspace. This
extracts the pid population and makes it so it is always executed
Subsurfaces (in most cases popups) aren't decorated by sway
and will never have any borders, but may be drawn beyond container
boundaries producing false positive when searching for edge.
So we want to skip edge search when handling mouse event on subsurface.
This adds complete support for the barconfig_update ipc event. This also
changes the bar command and subcommand handlers to correctly emit the
event. This makes it so all bar subcommands other than id and
swaybar_command are dynamically changeable at runtime. sway-bar.5 has
been updated accordingly
This matches i3's behavior of only focusing a container when pressed.
This allows for `bindsym button1 nop`, `bindsym BTN_LEFT nop`, or
`bindcode 272 nop` to be used to disable focusing when clicking on the
title (or with additional flags to bind{code,sym} other portions of
the container).
Without this additional condition, the user would need both
`bindsym button1 nop` and `bindsym --release button1 nop` to override
both the pressed and released behavior.
Focused layers are not cleared when destroyed, they are cleared on unmap.
Giving focus to an unmapped layer surface is (1) incorrect and (2) triggers a
use-after-free.
Closes: https://github.com/swaywm/sway/issues/4517
This make seat_update_capabilities set cursor image only if
there was no pointer cap before update. This avoid resetting
cursor to left_ptr if an input device is removed.
In cmd_mode, the mode is currently being reset to the default mode after
a mode subcommand handler is executed. This stores and restores the mode
instead
When moving to a scratchpad hidden container (using `move
[window|container] [to] mark <mark>`), this moves the container to the
scratchpad (equivalent to `move [window|container] [to] scratchpad`).
Previously, this would crash since the destination did not have a
workspace.
Match i3's behavior and only return one status response per command,
even if it applies to several nodes.
Also returns an error if the criteria returns an empty match.
Closes#4483
It looks like floating_scroll was still in the sway(5) man page as a
remnant of the 0.x era. This just removes it from the man page since it
is no longer a valid command. Mouse bindings with Button4-7 can be used
instead
This just adds a force option to cmd_xwayland that allows for xwayland
to be immediately launched instead of lazily launched. This is useful
for slower machines so it can be part of the startup time instead of
when the user is actively trying to use it
This keeps track of whether surfaces received a key press event and
will only send a key release event if the pressed event was sent. This
also requires changing the keycodes that are sent via wl_keyboard_enter
to only include those that were previously sent. This makes it so
surfaces do not receive key release events for keys that they never
received a key press for and makes it so switching focus doesn't leak
keycodes that were consumed by bindings.
This adds an axis handler to seatop_down so that it is possible to
manually scroll while having a mouse button down. This is mainly useful
for selecting text. Some applications may not automatically scroll when
the cursor is near the edge of the application or the user may just
prefer manually scrolling for more control over the scrolling speed.
This just specifies that both cmd_font and bar_cmd_font should be
specified using the pango font description and adds a link to the pango
documentation regarding the font description
This copies the width and height fractions from the container to the
container replacing it. Without setting these values, the container
is treated as a new container and throws off the existing sizing. Since
one container is replacing the other, it makes sense for the sizing to
remain the same.
Since each seat has its own focus, do not destroy a workspace until it
is no longer focused by any seat. This prevents seats from being forced
to evacuate the workspace just because another seat switched focus away
from it
In handle_seat_node_destroy, it was possible to focus the node attached
to the seat node that is being destroyed when an empty workspace was
being destroyed in a multiple seat environment. This resulted in
infinite recursion when attempting to destroy the workspace. This just
moves the seat node destruction higher so it cannot be the focus
inactive for the seat. This is the same ordering that is applied to
destruction of seat nodes for containers
Since output names can change in various configurations, including
DisplayPort MST, prefer output identifiers for the output priority.
Users can still use `workspace <ws> output <names-or-ids>`, but any
output that is programmatically added to the list will be added under
the output identifier. If the output name exists in the list (from the
user workspace output configs), then that will be retained instead of
switching to the output identifier for that output.
When applying an output config, an output may transform or be altered
in some way that effects the cursor. In order for the cursor images to
be updated properly, all cursors need to be rebased after applying
output configs.
This just adds a small quality of life improvement to the cursor hiding
functionality. The cursor will no longer be hidden unless all buttons
are released.
This enhances the opacity command to support relative assignment as well
as the currently implemented absolute assignment. The syntax is copied
from the same format that gaps uses for relative and absolute setting.
An example usage in a sway config looks like:
// relative change (this feature)
bindsym button4 opacity plus .1
bindsym button5 opacity minus .1
// absolute change (this feature)
bindsym button4 opacity set 1
bindsym button5 opacity set .3
// old way, still supported
bindsym button4 opacity 1
bindsym button5 opacity .3
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.
In sway_keyboard_config, do not change the keymap when the new keymap
is unchanged, unless this is during a config reload. The reasoning for
this is to prevent the effective layout from being reset to index 0 for
input config changes unrelated to the keymap.
This just fixes the check in set_send_events for whether the mode has
changed. LIBINPUT_CONFIG_SEND_EVENTS_ENABLED is 0 so the bitmask check
cannot be fixed, but Sway doesn't allow multiple modes to be set anyway
(not really sure why you would need to) so a basic equality check works
Sibling amounts were being calculated after the original fraction had
been altered. This led to broken resize amounts. Fix that by calculating
things upfront before adjusting values which also makes the code
cleaner.
For sanity checks also calculate the sibling amount with the
ceiling so we never go below the sanity check even by one pixel.
Fixes#4386
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
This commit si similar to wlroots' ca45f4490ccc ("Remove all wayland-server.h
includes").
When arranging the workspace, prev_x and prev_y should be ignoring the
current gaps otherwise the workspace diff_x and diff_y location deltas
will be off. When the deltas are off, each arrangement of the workspace
would incorrectly move floaters an extra -workspace->current_gaps.left
along the x-axis and an extra -workspace->current_gaps.top along the
y-axis.
This adds a libinput_config change type to the input event for when
the libinput config for a device changes
In order for this to be possible to track, the libinput config code
had to be refactored. It is now extracted into a separate file to
isolate it from the rest of the input management code.
This adds an ipc event related to input devices. Currently the
following changes are supported:
- added: when an input device becomes available
- removed: when an input device is no longer available
- xkb_keymap_changed: (keyboards only) the keymap changed
- xkb_layout_changed: (keyboards only) the effective layout changed
Similar to seat command, this provides an alias for the current output.
Instead of the output name or identifier, `-` can be used to operate on
the focused output by name and `--` can be used to operate on the
focused output by its identifier. This will prevent operating on the
no-op output when using either alias.
Adds a new commend "xkb_file", which constructs the internal
xkb_keymap from a xkb file rather than an RMLVO configuration.
This allows greater flexibility when specifying xkb configurations.
An xkb file can be dumped with the xkbcomp program.
Instead of tracking gaps per child apply gaps in two logical places:
1. In tiled containers use the layout code to add the gaps between
windows. This is much simpler and guarantees that the sizing of children
is correct.
2. In the workspace itself apply all the gaps around the edge. Here
we're in the correct position to size inner and outer gaps correctly and
decide on smart gaps in a single location.
Fixes#4296
Instead of using container->width/height as both the input and output
of the layout calculation have container->width_fraction/height_fraction
as the share of the parent this container occupies and calculate the
layout based on that. That way the container arrangement can always be
recalculated even if width/height have been altered by things like
fullscreen.
To do this several parts are reworked:
- The vertical and horizontal arrangement code is ajusted to work with
fractions instead of directly with width/height
- The resize code is then changed to manipulate the fractions when
working on tiled containers.
- Finally the places that manipulated width/height are adjusted to
match. The adjusted parts are container split, swap, and the input
seat code.
It's possible that some parts of the code are now adjusting width and
height only for those to be immediately recalculated. That's harmless
and since non-tiled containers are still sized with width/height
directly it may avoid breaking other corner cases.
Fixes#3547Fixes#4297
If there is more than one new window layout correctly by calculating the
default size of the new windows using the information of how many of
them there are in total.
This helps with issue #3547 but doesn't fix it in all situations. Things
now work correctly if the first layout of new windows happens after
leaving fullscreen. But if for some reason an arrange_container() gets
called while we are fullscreen the windows will still be incorrectly
sized after saved_width/saved_height get used to restore the first
window's size before going fullscreen.
Previously, `layout toggle` and `layout toggle split` would set L_VERT
when layout was L_HORIZ, otherwise it would set L_HORIZ. This meant
that when the layout was L_TABBED or L_STACKED, it would always be
L_HORIZ. This extends #4315 (which corrects the handling when multiple
layouts are given) to try prev_split_layout,
config->default_orientation, and then falling back to L_VERT when the
output is taller than wide and L_HORIZ when wider than tall.
This fixes the logic of split for layout toggle when the default
layout is L_TABBED or L_STACKED. When the default layout is L_TABBED
or L_STACKED, the container/workspace may not have a prev_split_layout.
This was causing L_NONE to be returned by get_layout_toggle, which was
being handled as a syntax error. This adds logic to try
config->default_orientation when prev_split_layout is L_NONE. If that
is also L_NONE, then L_VERT is used when the output is taller than
wide, otherwise, L_HORIZ is used.
In apply_output_config, this sets output->{width,height} using the
values in the output box. Previously, they were being set using
wlr_output_transformed_resolution, which takes the width and height
from the wlr_output and just checks whether they should be swapped
based on the transform. This did not take into account the output's
scale. wlr_output_effective_resolution could be used instead, which
handles both transform and scale. However, the values in the output box
have already been processed by wlr_output_effective_resolution so they
can just be used directly
This adds checks to the input_manager_libinput_reset_* functions to
only attempt resetting supported options on reload. This should have no
functional difference to the user, but will remove several `Failed to
apply libinput config: Unsupported configuration option` lines from the
log that can be noisy and potential red herrings.
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.
The function used for comparing two output names in the workspace
output priority lists was inverted. This was causing priority to not be
stored correctly resulting in workspaces not always being restored or
moved to the desired outputs
This allows for modes to be created, bindings to be added to modes, and
bindings to be removed from modes at runtime. Additionally, this also
allows for `mode <mode>` to be deferred in the config to set an initial
mode.
This separates the logic for seat subcommand handlers that only perform
actions on the seat and handlers that alter the seat config. The former
group can immediately free the seat config after running the command as
it is only used by the subcommand to find the name of the seat to
operate on. The latter group alters the seat config so it will need to
go through the storage and application stage (assuming success).
Without this change, the handlers listed in the config_handlers or
command_handlers arrays (depending on reading or active) in commands.c
would be valid subcommands. To make matters worse, they would also take
precedence over the defined subcommand handlers.
This corrects find_handler to only work on the handler array given
instead of implicitly trying others.
Since xwayland can only be enabled/disabled at launch, the xwayland
status should be retained on reload. Having `xwayland enabled|disabled`
in the config, should not cause `config->xwayland` to be invalid on
reload. This also returns `CMD_FAILURE` with a message that xwayland
can only be enabled/disabled on launch when trying to set the invalid
status on reload. This allows swaynag to notify the user that the
change will not take effect until sway is restarted.
Currently container_replace removes the container from the scratchpad
and re-adds it afterwards. For the split commands this results in the
container being send to the scratchpad, which results in a NULL segfault
if the same container should be shown.
Pass an optional workspace to root_scratchpad_add_container, if the
workspace is passed the window will continue to show on the workspace.
If NULL is passed it is sent to the scratchpad.
This was an issue if no other window except the scratchpad container was
on the workspace.
Fixes#4240
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 patch fixes faulty command parsing introduced by
f0f5de9a9e. When that commit allowed
criteria reset on ';' delimeters in commands lists, it failed to account
for its inner ','-parsing loop eating threw the entire rest of the
string.
This patch refactors argsep to use a list of multiple separators, and
(optionally) return the separator that it matched against in this
iteration via a pointer. This allows it to hint at the command parser
which separator was used at the end of the last command, allowing it to
trigger a potential secondary read of the criteria.
Fixes#4239
This allows for an optional validation stage when storing an input
config. Currently, only the xkb keymap is validated. If storing the
delta input config will result in any invalid xkb keymaps, the input
config will not be stored and error will be populated with the first
line of the xkbcommon log.
Before the delta input config is stored, this attempts to compile a
keymap with it. If the keymap fails to compile, then the first line of
the xkbcommon log entry will be included with a `CMD_FAILURE`, the
entire xkbcommon log entry will be included in the sway error log, and
the delta will not be stored.
This only handles basic issues such as a layouts not existing. This
will NOT catch more complex issues such as when a variant does
exist, but not for the given layout (ex: `azerty` is a valid variant,
but the `us` layout does not have a `azerty` variant).
Commit 190546fd31 failed to consider the
edge case where xwayland is disabled via the sway config. This leads to
a SEGFAULT when setting the xwayland cursor since the xwayland server is
not running.
This matches i3's behavior of only retaining criteria across comma
separated commands. When separating commands with a semicolon, the
criteria is reset and allows for new criteria to be set, if desired.
New 'seat <name> xcursor_theme <theme> [<size>]' command that
configures the default xcursor theme.
The default seat's xcursor theme is also propagated to XWayland, and
exported through the XCURSOR_THEME and XCURSOR_SIZE environment
variables. This is done every time the default seat's configuration is
changed.
This adds the missing argument count check after the --i3 flag
processing in cmd_hide_edge_borders. Without the check,
`hide_edge_borders --i3` would result in a SIGSEGV instead of a syntax
error. There are some minor adjustments to make it so nothing gets
altered if this check fails
handle_destroy would mark the output es being destroyed and commit the
transaction. Committing the transaction results in the output being
freed, the output manager can not retrieve the server reference
afterwards, resulting in the following use-after-free:

Retrieve the reference before the output is destroyed and update the
output_management state with the saved reference.
Subsurfaces need access to the parent get_root_coords impl for positioning in
popups. To do this, we store a reference to the parent view_child where
applicable.
Fixes#4191.
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.
This just changes the indentation of `sway/input/switch.c` to use
tabs instead of spaces since I messed up and missed it when approving
the PR that added the file.
For compatibility with i3, `bar mode` and `bar hidden_state` do not
require bar-ids (in the normal location) at runtime since they follow
the alternative syntax: `bar mode|hidden_state <option> [<bar-id>]`
This removes the incorrect error that the bar-id is missing for those
two bar subcommands
Running a command like this produced a confusing error message:
$ swaymsg bar bar-0 colors background #ff0000
Error: Unknown/invalid command 'bar-0'
This patch makes the error message use argv[1] instead of argv[0] (from
config_subcommand's implementation), so it actually uses the name of the
command, rather than the id of the bar.
Prior to this patch, if I ran something like this, sway would crash:
swaymsg bar height 50
or
swaymsg bar not-a-bar-id color bg #ff0000
This was in contrast to other bar subcommands, like status_command,
which would exit with a "No bar defined" message.
The difference between the subcommands that crashed and the ones that
exited was that some subcommands had a check to see if a bar was
specified, while others just assumed that it had been and carried on
until they segfaulted.
Because this check was identical in every subcommand it was present in,
and I couldn't think of a case where it would be valid to run a bar
subcommand without specifying which bar to apply it to, I moved this
check from individual subcommands into the bar command, which is already
responsible for actually setting the specified bar. This reduced code
duplication, and fixed the crash for the subcommands that were missing
this check.
This attempts to use the default keymap when the one defined in the
input config fails to compile. The goal is to make it so the keyboard
is always in a usable state, even if it is not the user's requested
settings as usability is more important.
This also removes the calls to `getenv` for the `XKB_DEFAULT_*` family
of environment variables. The reasoning is libxkbcommon will fallback
to using those (and then the system defaults) when any of the rule
names are `NULL` or an empty string anyway so there is no need for
sway to duplicate the efforts.
This fixes a typo in `merge_id_on_name` for output configs that
resulted in incorrect id-on-name output configs being generated.
Instead of using the output that matched the name or identifier, the
first output in the list was being used instead. This could cause
merging across unrelated output configs and preventing output configs
from being applied correctly
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
