Sway Screen Time CLI

Relevant Commands {#cmds}

• swaymsg -t get_tree to find the initial focused window.
• swaymsg -t subscribe -m '["window"]' says when the focused window has changed Both of these commands output JSON text in the terminal. We will convert this JSON text to a JSON object and then parse it to find the focused window. The efficiency in this program will come from effective parsing.
