# Event II
[](https://travis-ci.com/xyproto/event2) [](https://godoc.org/github.com/xyproto/event2) [](https://raw.githubusercontent.com/xyproto/event2/master/LICENSE) [](https://goreportcard.com/report/github.com/xyproto/event2)
A simple event system, for triggering events at certain times. This is the successor of [event](https://github.com/xyproto/event), which was needlessly complex.
## Example use
**Leet o'clock**
```go
package main
import (
"fmt"
"sync"
"time"
"github.com/xyproto/event2"
)
func main() {
// Create a new event system, with a loop iteration delay of 1 second
eventSys := event2.NewSystem(1 * time.Second)
// Add an event that will trigger every day at 13:37
eventSys.ClockEvent(13, 37, func() error {
fmt.Println("It's leet o'clock")
return nil
})
// Run the event system (not verbose)
eventSys.Run(false)
// Wait endlessly
var wg sync.WaitGroup
wg.Add(1)
wg.Wait()
}
```
**Clock**
```go
package main
import (
"fmt"
"time"
"github.com/xyproto/event2"
)
func clockSystem() *event2.EventSys {
sys := event2.NewSystem(1 * time.Second)
for hour := 0; hour < 24; hour++ {
for minute := 0; minute < 60; minute++ {
// Create new variables that can be closed over by the new function below
hour := hour
minute := minute
// Create a new event that will trigger at the specified hour and minute
sys.ClockEvent(hour, minute, func() error {
fmt.Printf("The clock is %02d:%02d\n", hour, minute)
return nil
})
}
}
return sys
}
func main() {
// Start the event system that will trigger an event at every minute
clockSystem().Run(false)
// Wait endlessly while saying "tick" and "tock" every second
for {
fmt.Println("tick")
time.Sleep(1 * time.Second)
fmt.Println("tock")
time.Sleep(1 * time.Second)
}
}
```
