Globals

Globals must be specified at the beginning of the configuration file. The supported global entries are the following:

Option	Default	Description
scheduler_tick_seconds	5	Number of seconds between scheduler ticks
randomize_checks_within_ticks	false	Whether or not condition checks should be uniformly randomized within the tick period

Both parameters can be omitted, in which case the default values are used: 5 seconds might seem a very short value for the tick period, but in fact it mimics a certain responsiveness and synchronization in checking event based conditions. Note that conditions strictly depending on time do not comply to the request of randomizing the check instant.

Note

These values can not be updated at runtime: possible changes of global parameters in the configuration file are only applied when the application is restarted.

No other global entries than the ones described above are accepted by whenever: in case an unknown entry is found, the application will exit with an error. As in items, a [[tags]] section is accepted, which can either be an array or a table whose entries and/or values are not checked: this section can be used by a wrapper in order to define global parameters that will not interfere with the actual configuration.
