Unify signal handling under wl_event_loop
Merge our signal handlers into a single function and let Wayland deal
with all the struct sigaction stuff.
ΔSLOC: -3
Separate drag icon from layers array and Lyr enum
If we treat the drag icon as distinct from other layers (it doesn't have
contents that are interactive, focusable, etc.), then we can iterate
over layers meaningfully with a simple for loop.
ΔSLOC: -8
Don't bother with ignoring SIGCHLD
It added complexity, especially with the differences in behavior between
handled and ignored signals across an exec().
Reset ignored signal handler in spawn() as well
fix startup_cmd SIGCHLD handler
Ignored handlers are not reset by exec() calls
activate lock surface in updatemons
Fixes an issue when swaylock does not receive input after turn off and then
turn on the outputs
Prevent using a wlr_layer_surface after destroying it, due to no available outputs
correctly check if a scene node is enabled
checking only wlr_scene_node.enabled may result in a false positive because it
does not consider if its ancestors are enabled as well.
remove unneeded check of `m` in arrange()
arrange must never be called with a NULL argument
use fixed-size type for client tags
while the size of `int` in most compilers is 32-bits, the size of int and all
other integer types are implementation defined, so make sure we can use up to
32-bits
remove tag labels from dwl
Tag labels are not used in dwl. Only the number of tags is important.
Tag labels should be defined for each tag in whatever status bar is
used.
display clients count in monocle symbol
- Replicate missing functionality from dwl to display the client count in monocle mode
- Add ltsymbol field to Monitor struct
- Display client count in monocle mode when greater than zero
- Tested with somebar and dwlb
Fix spacing and replace it with tabs
