Scheduling

every 1 seconds registers a callback; the example then drives the registry manually with run_scheduled_once() for testability. In production, c4 serve runs the scheduler in a real loop.

# Cron-style scheduling — `every N seconds { ... }` registers a callback;
# in M1 no daemon runs by default, so we manually drive the registry.

use cobra4.runtime.core as rt

state = {"ticks": 0}

fn tick() {
    state["ticks"] = state["ticks"] + 1
    log("tick", ticks=state["ticks"])
}

every 1 seconds {
    tick()
}

# Drive the registry in M1: invoke each registered callback once.
rt.run_scheduled_once()
rt.run_scheduled_once()
rt.run_scheduled_once()

log("done", final=state["ticks"])

Run it

c4 run examples/05_schedule.c4
