英文:
I'm trying to integrate cobra in my program
问题
我正在参考spf13/cobra。
我使用go get github.com/spf13/cobra/cobra下载了cobra包，并在我的程序中导入了"github.com/spf13/cobra"，然后使用go install github.com/spf13/cobra/cobra进行安装。
这是我的程序 - 它是一个计算器，可以实现任意数量的输入，但目前只从用户那里获取两个输入。我想在这个程序中使用cobra。
package main
import (
"fmt"
"github.com/spf13/cobra"
)
func add(m ...int) int {
sum := 0
for _, a := range m {
sum += a
}
return sum
}
func sub(m ...int) int {
sub := m[0]
for _, a := range m[1:] {
sub -= a
}
return sub
}
func mul(m ...float32) float32 {
pro := float32(1)
for _, a := range m {
pro *= a
}
return pro
}
func div(m ...float32) float32 {
quo := m[0]
for _, a := range m[1:] {
quo /= a
}
return quo
}
var i int
func display() {
fmt.Println("选择操作：1：加法 2：减法 3：乘法 4：除法")
fmt.Scanln(&i)
}
func main() {
display()
var v1,v2 int
fmt.Println("输入两个数字并按回车")
fmt.Scanln(&v1)
fmt.Scanln(&v2)
switch i {
case 1:
fmt.Println(add(v1,v2))
case 2:
fmt.Println(sub(v1,v2))
case 3:
fmt.Println(mul(float32(v1),float32(v2)))
case 4:
fmt.Println(div(float32(v1),float32(v2)))
}
}
英文:
I was referring to spf13/cobra.
I downloaded the cobra package using go get github.com/spf13/cobra/cobra and imported "github.com/spf13/cobra" in my program and then installed it using go install github.com/spf13/cobra/cobra.
This is my program - It is a calculator which can be implemented of number of inputs , but for now only 2 are taken from the user. I wanted to use cobra in this program.
package main
import (
"fmt"
"github.com/spf13/cobra"
)
func add(m ...int) int {
sum := 0
for _, a := range m {
sum += a
}
return sum
}
func sub(m ...int) int {
sub := m[0]
for _, a := range m[1:] {
sub -= a
}
return sub
}
func mul(m ...float32) float32 {
pro := float32(1)
for _, a := range m {
pro *= a
}
return pro
}
func div(m ...float32) float32 {
quo := m[0]
for _, a := range m[1:] {
quo /= a
}
return quo
}
var i int
func display() {
fmt.Println("Choose the operation : 1:Addition 2:Subtration 3:Multiplication 4:Division ")
fmt.Scanln(&i)
}
func main() {
display()
var v1,v2 int
fmt.Println("Enter 2 numbers with enter")
fmt.Scanln(&v1)
fmt.Scanln(&v2)
switch i {
case 1:
fmt.Println(add(v1,v2))
case 2:
fmt.Println(sub(v1,v2))
case 3:
fmt.Println(mul(float32(v1),float32(v2)))
case 4:
fmt.Println(div(float32(v1),float32(v2)))
}
}

你需要先运行go get github.com/spf13/cobra/cobra。go install只能安装你已经下载的包，而go get会下载并安装一个包。
英文:
You need to run go get github.com/spf13/cobra/cobra first. go install can only install packages you've already downloaded, go get downloads and installs a package.
