go - 没有参数匹配的golang眼镜蛇子命令

我想使用cobra创建golang CLI。目前，它运行良好。我创建了类似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。

我创建了匹配的参数，

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)%s\n", chalk.Red, chalk.Reset)
        }
        if stringUtil.Contains(args, "user") {
            createUser()
        }
        if stringUtil.Contains(args, "partner") {
            createPartner()
        }
   },
}

但是我认为有一种更好的方法可以使用眼镜蛇而不是使用像这样的参数匹配。有什么建议吗？

最佳答案

我有点落水了；但是是的，appCmd.Addcommand(newCmd)是您想要的。

(在您发布答案之前，我已经开始进行此工作，但是我不想删除代码)

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()
}
