Scheduling Actions

Every driver can schedule events to occur in a number of different ways. Schedules are automatically cleared when a driver is terminated.

  • Integer arguments are in milliseconds. 1000 == 1 second

  • Strings can be used for a friendly representation of the time

    • '30s' == 30 seconds

    • '5m' == 5 minutes

    • '1w2d3h5m' == 1 week, 2 days, 3 hours and 5 minutes

    • '2Y1M' == 2 years, 1 month

Examples

schedule.every('1m') do
    # perform some action, such as polling
end

schedule.in(500) do
    # ...
end

schedule.at(Time.now + 2.hours) do
    # ...
end

schedule.at('2018-02-02T15:32:41+11:00') do
    # ...
end

# Every day at 8am
schedule.cron('0 8 * * *') do
    # ...
end

# Canceling an individual schedule
@email_sched = schedule.in(500) do
    send_email
end
@email_sched.cancel

There are often situations where you want to run the block immediately.

def connected
    schedule.every('1m', :run_now) do
        poll_current_state
    end
end

CRON also supports time zones - which should always be configured

schedule.cron('0 8 * * *', timezone: 'Sydney') do
    # ...
end

See the list of supported time zone strings and information about time zones.
