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.
This fixes a typo on the malloc line in ipc_send_workspace_command. The
plus one to the size for the null-terminator was outside of the malloc
call, which was causing the incorrect pointer to be freed later in the
function.
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.
Previously, the success of `getline` was tested by checking if the
buffer it allocates is nonempty and has a nonzero first byte. As
`getline` does not explicitly zero out its memory buffer, this may
fail (e.g., with AddressSanitizer). Instead, we check that at least one
character was returned on standard output.
Also, trailing newlines (if present) are now removed.
