An easy-to-use task scheduler that can run arbitrary blocks: * Every so often (e.g. every hour starting now)* Daily at a given time* Periodically starting at a given time (e.g. every other hour starting a noon)* Per a provide schedule (e.g. using Schedule instance you can run tasks every Monday and Friday)* A one time task at some point in the future For ease of use tasks can be blocks passed to the scheduler (or any object that understands #value). For example: "Start a new task scheduler and keep it around"scheduler := TaskScheduler new.scheduler start. "Let's save the image every hour"schedulerdo: [Smalltalk snapshot: true andQuit: false]every: 60 minutes. "Let's run a backup at 2am every day"schedulerdo: ["backup code here"]at: '2am' "Let's perform a bank transfer every other hour starting at 1pm"schedulerdo: ["swiss bank account transfer code"]at: '1pm'every: 2 hours. "Let's do a one time email reminder"schedulerdoOnce: ["email reminder to go on honeymoon"]at: '2005-1-15T8:00' "You can delete tasks by sending #delete to them"(scheduler taskAt: 1) delete "Stop the scheduler from running -- but don't delete its tasks"scheduler stop.
