Compositor Setup

windowrule = float, ^(k-launcher)$
windowrule = center, ^(k-launcher)$
bind = SUPER, Space, exec, k-launcher
Sway (~/.config/sway/config):
for_window [app_id="k-launcher"] floating enable, move position center
bindsym Mod4+space exec k-launcher

External Plugins
Drop in community plugins — any language, no recompilation. Plugins are executables that communicate over stdin/stdout JSON:
# ~/.config/k-launcher/config.toml
[[plugins.external]]
name = "my-plugin"
path = "/usr/lib/k-launcher/plugins/my-plugin"
See Plugin Development for the full protocol.
