about grtm

grtm is a tool to manage golang goroutines.use this can start or stop a long loop goroutine.

Getting started

go get github.com/scottkiss/grtm

Create normal goroutine

package main

import (
        "fmt"
        "github.com/scottkiss/grtm"
        "time"
       )

func normal() {
    fmt.Println("i am normal goroutine")
}

func main() {
        gm := grtm.NewGrManager()
        gm.NewGoroutine("normal", normal)
        fmt.Println("main function")
        time.Sleep(time.Second * time.Duration(5))
}
~

Create normal goroutine function with params

package main

import (
        "fmt"
        "github.com/scottkiss/grtm"
        "time"
       )

func normal() {
    fmt.Println("i am normal goroutine")
}

func funcWithParams(args ...interface{}) {
    fmt.Println(args[0].([]interface{})[0].(string))
    fmt.Println(args[0].([]interface{})[1].(string))
}

func main() {
        gm := grtm.NewGrManager()
        gm.NewGoroutine("normal", normal)
        fmt.Println("main function")
        gm.NewGoroutine("funcWithParams", funcWithParams, "hello", "world")
        time.Sleep(time.Second * time.Duration(5))
}

Create long loop goroutine then stop it

package main

import (
        "fmt"
        "github.com/scottkiss/grtm"
        "time"
       )

func myfunc() {
    fmt.Println("do something repeat by interval 4 seconds")
        time.Sleep(time.Second * time.Duration(4))
}

func main() {
gm := grtm.NewGrManager()
        gm.NewLoopGoroutine("myfunc", myfunc)
        fmt.Println("main function")
        time.Sleep(time.Second * time.Duration(40))
        fmt.Println("stop myfunc goroutine")
        gm.StopLoopGoroutine("myfunc")
        time.Sleep(time.Second * time.Duration(80))
}

output
