for-loop - 了解如何正确使用for…range循环

目前，我有一个包含以下代码的go程序。

package main

import "time"
import "minions/minion"

func main() {
    // creating the slice
    ms := make([]*minion.Minion, 2)

    //populating the slice and make the elements start doing something
    for i := range ms  {
        m := &ms[i]
        *m = minion.NewMinion()
        (*m).Start()
    }

    // wait while the minions do all the work
    time.Sleep(time.Millisecond * 500)

    // make the elements of the slice stop with what they were doing
    for i := range ms {
        m := &ms[i]
        (*m).Stop()
    }
}

这里NewMinion()是一个返回*minion.Minion的构造函数

该代码可以正常工作，但是在我每次使用m := &ms[i]循环时都必须编写for ... range，我觉得应该有一种更友好的代码编写器来解决此问题。

理想情况下，我希望可以进行以下操作(使用makeed＆range标签):

package main

import "time"
import "minions/minion"

func main() {
    // creating the slice
    ms := make([]*minion.Minion, 2)

    //populating the slice and make the elements start doing something
    for _, m := &range ms  {
        *m = minion.NewMinion()
        (*m).Start()
    }

    // wait while the minions do all the work
    time.Sleep(time.Millisecond * 500)

    // make the elements of the slice stop with what they were doing
    for _, m := &range ms {
        (*m).Stop()
    }
}

不幸的是，这还不是语言功能。关于从代码中删除m := &ms[i]的最佳方法的任何考虑？还是没有比这更省力的方法了？

最佳答案

您的第一个示例是一个指针 slice ，您无需获取 slice 中指针的地址，然后每次都取消对指针的引用。更惯用的Go看起来像(略作编辑即可在没有“minion”包的情况下在操场上运行):

http://play.golang.org/p/88WsCVonaL

// creating the slice
ms := make([]*Minion, 2)

//populating the slice and make the elements start doing something
for i := range ms {
    ms[i] = NewMinion(i)
    ms[i].Start()

    // (or equivalently)
    // m := MewMinion(i)
    // m.Start()
    // ms[i] = m
}

// wait while the minions do all the work
time.Sleep(time.Millisecond * 500)

// make the elements of the slice stop with what they were doing
for _, m := range ms {
    m.Stop()
}
