Signal Register

Package argcv/sigr implements a simple signal proxy, which is used to manage the signal easier for multiple tasks.

You can add one or a few functions after interrupt/quit/.... signal comes and befure really quit.

Currently, the process sequence are not in order.

Install

go get -u github.com/argcv/sigr

Example

package main

import (
	"fmt"
	"github.com/argcv/sigr"
	"time"
)

func main() {
	// register a new name
	// this is used to
	name1 := sigr.RegisterOnStopFuncAutoName(func() {
		fmt.Println("Hello, World! #1")
	})
	name2 := sigr.RegisterOnStopFuncAutoName(func() {
		fmt.Println("Hello, World! #2")
	})
	sigr.RegisterOnStopFunc("customized name", func() {
		fmt.Println("Hello, World! #3")
	})
	fmt.Println("name1:", name1, "name2:", name2)
	sigr.RegisterOnStopFunc(name1, func() {
		fmt.Println("Hello, World! #1 #overridden")
	})
	sigr.UnregisterOnStopFunc(name2)
	// default: true
	sigr.SetQuitDirectyl(true)
	// get verbose log
	sigr.VerboseLog()
	// without verbose log, your printing is still work here
	//sigr.NoLog()
	// you may type ctrl+C to excute the functions (name1 and "customized name")
	time.Sleep(time.Duration(20 * time.Second))
}

The output seems as follow:

$ go run example.go
name1: __auto_1 name2: __auto_2
