status->text should not be freed here. There are two scenarios:
* status->text has been set to an error by status_error. In this case
the value shouldn't be freed because it's always a reference to a
constant.
* status->text has been set to status->buffer because the bar is in
text protocol mode. In this case it's a double free because the
buffer is already freed after.
This fixes a few issues with swaybar's cursor scaling:
1. The cursor scale is now changed when the output scale changes
2. The cursor scale is no longer bound by the max output scale when
swaybar is launched
3. Related to the previous item, the cursor is no longer tiny on low
scale outputs after the max output scale has changed
This also bumps up `wl_compositor` to version 4 to allow usage of
`wl_surface_damage_buffer`.
When there are outputs with mixed scales, it was possible for swaybar to
alter `block->separator_block_width` for an output with a higher scale,
and use the changed value for a lower scale output. This caused there to
be larger than normal separation between blocks on the lower scale
outputs. The issue is more obvious the larger the scale difference
between the highest scale output and the lowest scale output.
This fixes the issue by using a local variable that is originally set to
`block->separator_block_width` for rendering, but if it needs to be
increased, the local variable is the only thing touched.
When `block->urgent` is set, use the urgent colors. This matches i3bar's
behavior. Previously, swaybar just ignored the property.
This also adds in rendering for right borders, which was missing.
Adds the bar subcommand `gaps <amount>|<horizontal> <vertical>|<top>
<right> <bottom> <left>` to set gaps for swaybar. Due to restrictions on
margins for a layer_surface, only the sides that are anchored to an edge
of the screen can have gaps. Since there is support for per-side outer
gaps for workspaces, those should be able to be used instead for the
last side.
The positions "left" and "right" are not allowed by the man page, remove them
from the allowed positions. Also print an error to stderr if we default to the
bottom position.
Fixes#2878
* The loop functions are now prefixed with `loop_`.
* It is now easy to add timers to the loop.
* Timers are implemented using pollfd and timerfd, rather than manually
checking them when any other event happens to arrive.
Previously, when the bar was hidden, the height would be set to 0.
This meant that if the bar was empty upon reshow, it would not render
since the height was still 0, which made it seem there was a problem.
Now, the height is not reset, but the width is, to indicate upon reshow
that the layer surface needed reconfiguring.
Since wayland does not currently allow swaybar to create global
keybinds, this is handled within sway and sent to the bar using a custom
event, so as not to pollute existing events, called bar_state_update.
As well as adding the hidden_state property to the bar config struct,
this commit handles barconfig_update events when the mode or
hidden_state changes, and uses a new function determine_bar_visibility
to hide or show the bar as required, using, respectively,
destroy_layer_surface, which is also newly added, and add_layer_surface,
which has been changed to allow dynamically adding the surface.
