Joe Bot - Cron Module

Emiting events on recurring schedules. https://github.com/go-joe/joe

---

This repository contains a module for the Joe Bot library.

Getting Started

This library is packaged as Go module. You can get it via:

go get github.com/go-joe/cron

Example usage

This module allows you to run arbitrary functions or emit events on a schedule using a cron expressions or simply an interval expressed as time.Duration.

package main

import (
	"time"
	"github.com/go-joe/joe"
	"github.com/go-joe/cron"
)

type MyEvent struct {}

func main() {
	b := joe.New("example-bot",
		// emit a cron.Event once every day at midnight
		cron.ScheduleEvent("0 0 * * *"),
		
		// emit your own custom event every day at 09:00
		cron.ScheduleEvent("0 9 * * *", MyEvent{}), 
		
		// emit your own custom event every day at 09:00:30
		cron.ScheduleEvent("30 0 9 * * *", MyEvent{}),

		// cron expressions can be hard to read and might be overkill
		cron.ScheduleEventEvery(time.Hour, MyEvent{}), 
		
		// sometimes its easier to use a function
		cron.ScheduleFunc("0 9 * * *", func() { /* TODO */ }), 
		
		// functions can also be scheduled on simple intervals
		cron.ScheduleFuncEvery(5*time.Minute, func() { /* TODO */ }),
    )
	
	err := b.Run()
	if err != nil {
		b.Logger.Fatal(err.Error())
	}
}
