没有参数匹配的 Golang眼镜蛇子命令

Question

我想用眼镜蛇创建 golang CLI。目前，它运行良好。我创造了类似foobar create --username johndoe的东西.但是我需要像foobar create user --username johndoe这样的子命令.有user子命令。

我用参数匹配创建了，

var applicationCmd = &cobra.Command{
   Use:   "application",
   Short: "Create/Read/Update application",
   Long: `You can create any user or partner.`,
   Run: (cmd *cobra.Command, args []string) {
        if len(args) < 1 {
            fmt.Printf("%sPlease choose any object that you want to change e.g (user, partner)%sn", chalk.Red, chalk.Reset)
        }
        if stringUtil.Contains(args, "user") {
            createUser()
        }
        if stringUtil.Contains(args, "partner") {
            createPartner()
        }
   },
}

但我认为有一种更好的方法可以使用眼镜蛇而不是使用这样的参数匹配来做到这一点。有什么建议吗？

我有点过火了;但是，是的，appCmd.Addcommand（newCmd）就是你要找的。

（在您发布答案之前，我已经开始研究这个问题，但我不想废弃代码）

package main
import (
"github.com/spf13/cobra"
"fmt"
)
var rootCmd = &cobra.Command{
    Use:   "app",
    Run: func (cmd *cobra.Command, args []string) {
    },
}
var makeU = &cobra.Command{
    Use:   "makeU",
    Short: "makes a user",
    Long: "Prints stuff about the user. You could also use the flags in your addPartner() function",
    Run: func (cmd *cobra.Command, args []string) {
        fmt.Println("User's name: " + uName)
        fmt.Println("User's number: " + uNumber)
        fmt.Println("User's other stuff: " + uOtherStuff)
    },
}
var makeP = &cobra.Command{
    Use:   "makeP",
    Short: "makes a partner",
    Long: "Prints stuff about the partner. You could also use the flags in your addPartner() function",
    Run: func (cmd *cobra.Command, args []string) {
        fmt.Println("Partner's name: " + uName)
        fmt.Println("Partner's number: " + uNumber)
        fmt.Println("Partner's other stuff: " + uOtherStuff)
    },
}
// adds commands
func addCommands() {
    rootCmd.AddCommand(makeU)
    rootCmd.AddCommand(makeP)
}
// adds flags
var pName, pNumber, pOtherStuff string
var uName, uNumber, uOtherStuff string
func init() {
    makeU.Flags().StringVar(&uName, "username", "default", "--username=<user's name>")
    makeU.Flags().StringVar(&uNumber, "usernumber", "default", "--usernumber=<user's number>")
    makeU.Flags().StringVar(&uOtherStuff, "userother", "default", "--userother=<user's other stuff>")
    makeP.Flags().StringVar(&pName, "partnername", "default", "--partnername=<partner's name>")
    makeP.Flags().StringVar(&pNumber, "partnernumber", "default", "--partnernumber=<partner's number>")
    makeP.Flags().StringVar(&pOtherStuff, "partnerother", "default", "--partnerother=<partner's other stuff>")
}

func main() {
    addCommands()
    rootCmd.Execute()
}

我已经解决了这个问题。只需添加新的眼镜蛇命令即可applicationCmd

applicationCmd.AddCommand(yourNewCommand)
