### default font (for e.g. window titles)
font @font@

### tab colors (#border #background #text [#indicator #childBorder])
# focused & unfocused are the main interest
# urgent is used when an inactive window wants attention (e.g. terminal rings a bell)
# colors are synchronized with waybar and mpv
client.focused          #1f5e54 #418379 #ffffff
client.focused_inactive #1f5e54 #5f676a #ffffff

# TODO: populate background from /run/current-system/sw/etc/... instead of hard-coded nix path
output '*' bg "@background@" fill

### 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
titlebar_padding 12 1
title_align center

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

# 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.

# - DISPLAY
