# urgent is used when an inactive window wants attention (e.g. terminal rings a bell)

### pixel boundary between windows
# hide_edge_borders --i3 means that single-window workspaces never show window bar
hide_edge_borders --i3 smart
default_border pixel 1
titlebar_border_thickness 1
# XX YY distance from edge of window title to edge of text
# the YY distance here determines the heigh of the overall title

### focus_wrapping: behavior when trying to focus past the edge of a container
####   no  => preserve last focus. helpful mostly when `focus_follows_mouse yes`

# manually export PATH here, since all my user services need that, and sane-sandboxed implementation depends on it.
# also, manually export XDG_DATA_DIRS. glib fails in weird ways (e.g. thinks everything is application/x-octet-stream mime type) without it.

#
# XXX: dbus-update-activation-environment --systemd is ASYNCHRONOUS. it returns before the systemd environment is actually updated.
# hence, call `systemctl import-environment` ourselves. i could probably remove the dbus stuff and be safe, but at least for now it's an OK backup.
exec --no-startup-id systemctl --user import-environment PATH XDG_DATA_DIRS DISPLAY WAYLAND_DISPLAY SWAYSOCK XDG_CURRENT_DESKTOP
exec --no-startup-id dbus-update-activation-environment --systemd PATH XDG_DATA_DIRS DISPLAY WAYLAND_DISPLAY SWAYSOCK XDG_CURRENT_DESKTOP

# previously: `include /etc/sway/config.d/*` was needed for xdg-desktop-portal-* to work.
# stock nixos `programs.sway` would setup /etc/sway/config.d with additional variables to import to the dbus env.
# but now i'm doing that manually:
# - DISPLAY
# - WAYLAND_DISPLAY
# - SWAYSOCK
# - XDG_CURRENT_DESKTOP
# include /etc/sway/config.d/*

# signal to systemd that sway is active,
# and therefore let it start any downstream services (e.g. apps that would like to auto-start)
# see `systemctl --user cat sway-session` for links to docs
exec --no-startup-id systemctl start --user sway-session.service
