API ScriptAuthor: manveti
Version: 0.11
Last Modified: 2015-08-10
Code: cron
Dependencies: None
Conflicts: None

Cron allows a user to schedule commands to run at some point in the future. Jobs can be scheduled based on the turn tracker or clock time (relative to now or at some specific time in the future), and can optionally recur at a specified interval. Each job is given a unique ID, which can be used to remove it at a later time.

It is recommended that this script be used in conjunction with the CommandShell module, which will improve output formatting and command discovery, as well as enabling the scheduling and execution of CommandShell-aware commands.

Parameter Values
options The !cron command accepts the following options:
  • -h, --help: Displays a help message and exits.
  • -r N, --rounds N: The first execution of the command will be in N rounds. If an initiative count is not specified (see below), the current count will be used (or 0, if none is available). Cannot be used with time-based arguments.
  • -c N, --count N: The command will execute on initiative count N. If the number of rounds in the future is not specified (see above), it will default to the next time the specified count comes up. Cannot be used with time-based arguments.
  • -t T, --time T: The first execution of the command will be at time T (HH:MM:SS). If not all values are given, zeroes will be added to the smaller end (e.g. "1:23" will be interpreted as "1:23:00"). Times are in GMT and will be interpreted to be within the next 24 hours. Cannot be used with initiative-based arguments.
  • -a T, --after T: The first execution of this command will be after interval T (HH:MM:SS). If not all values are given, zeroes will be added to the larger end (e.g. "1:23" will be interpreted as "00:01:23"). Cannot be used with initiative-based arguments.
  • -i I, --interval I: The command will be repeated ever I rounds or I time (HH:MM:SS). If rounds or count is given, or if I is a single number, I will be considered a number of rounds. Otherwise, I will be considered a time interval, with zeroes added to the larger end to fill missing values (e.g. "1:23" will represent 1 minute and 23 seconds). If no first execution time is specified, the first execution will be I rounds or seconds in the future.
  • -f USER, --from USER: The command will be executed as USER. This need not be a player or character in the game.
  • -A N, --advance N: Advance the round counter by N rounds. This will cause initiative-based jobs to advance as if the tracker had been advanced through N full rounds.
  • -l, --list: List all scheduled jobs.
  • -R, --remove: Remove all specified jobs. All other arguments will be considered job IDs (so multiple jobs can be removed with one command like "!cron -R 1 5 8").


!cron -r 10 The bomb's timer reaches zero! It explodes for [[10d10]] damage.
Called on the initiative count in which the bomb's timer is set, it will explode in 10 rounds.
!cron -c 12 -i 1 -f "Hey, eejit!" /w gm Don't forget the spider's turn
A forgetful GM might use this subtle reminder that the party's mage summoned a spider which acts on the mage's initiative count (12, in this example).
!cron -f "Acid Rain" -i 1 The acid burns for [[2d6]] damage.
Inline roll results are stripped from the command and replaced with the original roll expression. Long story short: the above gives a new damage roll each round.
!cron -f Nanny -t 23:00 Bedtime for sleepy-head. Time to wrap things up.
Be aware that the time zone is GMT, not local time of the client who runs the command.
!cron -a 30 Hey! It's 30 seconds later than when I typed this.
Probably more useful with larger delay amounts.
!cron -t 0:00:00 -i 1:00:00 /desc The clock chimes.
This will fire every hour, on the hour. (Can also just do "-t 0").
!cron -r 10 "!cron -R 42"
This will remove job 42 after 10 rounds. Note that the quotes are required around commands which contain tokens which are valid !cron arguments (e.g. "-R"). Without the quotes, this will immediately remove job 42.
