server_init ignores all errors. In practice, theses result in a
segfault, potentially much later and losing any unsaved work.
Properly handle initialisation errors and bail immediately.
(cherry picked from commit 1606311553)
Maintain a 1:1 relationship between workspace groups and outputs, so
that moving a workspace across groups effectively moves it across
outputs.
ext_workspace_handle_v1::id is never emitted; sway has no concept of ids
or of stable vs temporary workspaces. Everything is ephemeral to the
current session.
ext_workspace_handle_v1::coordinates is never emitted; sway does not
organise workspaces into any sort of grid.
ext_workspace_handle_v1::assign is mostly untested, because no client
current implements this. Perhaps it's best to not-advertise the feature
for now?
Deactivating a workspace is a no-op. This functionality doesn't really
align with sway, although it could potentially be implemented to "switch
to previous workspace on this output" as a follow-up.
Removing a workspace is a no-op.

(cherry picked from commit f50f78c0d9)
Move workspace_move_to_output out of the command handler, so it can be
re-used for ext_workspace_handle_v1::assign.
(cherry picked from commit 7ba11d6dee)
workspace_valid_on_output() and workspace_next_name() check whether an
output appears anywhere in a workspace's output list, ignoring priority
order. This allows a lower-priority output to claim a workspace even
when a higher-priority output is available.
Fix by stopping early when iterating the output list: if a different
available output is found before the current one, the workspace belongs
to that higher-priority output.
Node destruction currently runs through the transaction system such that
a particular node is only destroyed after its use in an ongoing
transaction. If a node is dirtied after the node is marked as destroying
but before it is destroyed, the pointer added to dirty_nodes would
become a dangling pointer once the node was destroyed.
Do not dirty destroying nodes, and ensure that destroying is only set
after the last dirty.
This reverts commit e28e6484e8.
This change tried to remove nodes from all points of reference to allow
immediate destruction. However, it missed things like the children lists
cloned by transaction states of parent nodes.
Adding all that extra cleanup would not be in the spirit of a PR
claiming to simplify teardown. Let's wait for someone to come up with a
cleaner approach instead.
Fixes: https://github.com/swaywm/sway/pull/8738
A sway_node may end up being referenced in either a queued transaction,
pending transaction or as a dirty node. To manage this, the transaction
system has been responsible for destroying containers, workspaces and
outputs at the end of their last referenced transaction.
This significantly complicates the teardown flow of surfaces and
outputs. Instead, remove the node from transactions and dirty lists so
that the callsite can remove and free the node immediately.
workspace_output_get_highest_available took an output to exclude as
argument, meant to avoid accidentally reselecting an output we are
evacuating workspaces from.
Outputs are now removed from the list before we evacuate, making
exclusion unnecessary. Remove the argument.
The only reason it's included there is for a declaration of
struct sway_server, but we can just forward-declare it.
This avoids rebuilding almost all of Sway when touching server.h.
All other server.h includes are from source files, not headers.
Add a subcommand for `smart_gaps` that enables outer gaps only
on workspaces with exactly one visible child.
Also add documentation for `smart_gaps toggle`.
Instead of disabling it for some workspace subcommands, this explicitly
calls it only in the 2 places it's actually needed: for switching to a
named or numbered workspace.
This extracts the code to a separate workspace_auto_back_and_forth
function.
It also removes the bool argument by adding an extra if statement at the call
site, and repurposes the no_auto_back_and_forth variable to
auto_back_and_forth for simpler understanding.
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.
Instead, use the state struct for both current and pending.
workspace_squash is container_flatten in the reverse
direction. Instead of eliminating redundant splits that are
parents of the target container, it eliminates pairs of
redundant H/V splits that are children of the workspace.
Splits are redundant if a con and its grandchild have the
same layout, and the immediate child has the opposite split.
For example, layouts are transformed like:
H[V[H[app1 app2]] app3] -> H[app1 app2 app3]
i3 uses this operation to simplify the tree after moving
heavily nested containers to a higher level in the tree via
an orthogonal move.
In i3, the workspace_layout command does not affect the
workspace layout. Instead, new workspace level containers
are wrapped in the desired layout and the workspace layout
always defaults to the output orientation.
To query whether a container is sticky, checking `con->is_sticky` is
insufficient. `container_is_floating_or_child` must also return true;
this led to a lot of repetition.
This commit introduces `container_is_sticky[_or_child]` functions, and
switches all stickiness checks to use them. (Including ones where the
container is already known to be floating, for consistency.)
Sticky floating containers on an otherwise empty workspace can only be
evacuated if the new output has an active workspace. The noop output may
not have one and in that case we have to move the whole workspace to the
new output.
If moving e.g. `T[app app]` into a new workspace with `workspace_layout
tabbed`, then post-move the tree in that workspace will be `T[T[app
app]]`. This still happens with horizontal or vertical workspace layout,
but is less visible since those containers have no decorations.
Fixes#5426.
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
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.
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
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 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
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 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 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 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 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 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 combines `output_by_name` and `output_by_identifier` into a single
function called `output_by_name_or_id`. This allows for output
identifiers to be used in all commands, simplifies the logic of the
callers, and is more efficient since worst case is a single pass through
the output list.
