[go-nuts] How to debug goroutine with dlv

[mountainfpf]

 When i debug go func() with dlv, use s to go into but not exec. 

Who is familiar with dlv debugging go source code？
   
thanks！

package main

import "fmt"

func main() {
    a := make(chan int)
    go func() {
        a <- 1
    }()

    for {
        select {
        case i, ok := <-a:
            fmt.Println("a:", i, "\tStatus:", ok)
        default:
            fmt.Println("a over")
            return
        }
    }
}

go build -o chan -gcflags="-N -l" chan.go

dlv exec ./chan
