Events

Walker can execute shell commands on lifecycle events. Configure under [events] in your config.

Hooks

• on_launch: when the UI opens
• on_activate: when the window receives focus
• on_selection: when an entry is activated
• on_exit: when the UI closes
• on_query_change: whenever the query string changes

Example

[events]
on_launch = "notify-send 'Walker' 'Opened'"
on_selection = "paplay /usr/share/sounds/freedesktop/stereo/message.oga"
on_exit = "notify-send 'Walker' 'Closed'"

Notes:

• Commands run in a shell; keep them idempotent and quick.
• Use environment variables if needed; see .env support via ~/.config/walker/.env.
