onexit
Package helps with running functions on app exit (receiving an OS signal), based on their priority.
Functions will be registtered with a priority and be called based on that priority - a priority queue is implemented by employing a heap.
The last statement of main() can be <-onexit.Done() which waits for all registered functions to run, before exit.
package main
import (
"github.com/dc0d/onexit"
)
func main() {
onexit.Register(Logout, 100)
onexit.Register(func() { println("\n") })
// ...
<-onexit.Done()
}
func init() {
onexit.Register(SyncLogger, -100)
}
Calling os.Exit(code) explicitly, will not trigger onexit to run registered functions. Because it causes the program to exit without waiting for anything. Instead, call onexit.ForceExit(code) which waits for all registered functions to execute and then calls os.Exit(code).
