我有以下Cobra子命令：

package stripeCommands

import (
    "fmt"
    "cmd/cliConstants"
    "github.com/spf13/cobra"
    "log"
)

var (
    deleteCustomerCommand = &cobra.Command{
        Use:        "delete",
        Short:      "Delete Stripe customer(s) by ids.",
        Args:       cobra.MinimumNArgs(1),
        ArgAliases: []string{"stripe_customer_id"},
        PreRun: func(cmd *cobra.Command, args []string) {

        },
        Run: func(cmd *cobra.Command, args []string) {
            log.Printf("IDs: %v", args)
        },
    }
)

func init() {
    flags := deleteCustomerCommand.Flags()

    // -k|--stripe-api-key|STRIPE_API_KEY
    flags.StringP(cliConstants.CLIFlagStripeAPIKey, "k", "",
        fmt.Sprintf("The Stripe API key. [env: %s]", cliConstants.EnvVarStripeAPIKey))
}

这个想法是通过调用它./my-app stripe customers delete -k $STRIPE_API_KEY $CUSTOMER_ID_1 $CUSTOMER_ID_2。

虽然cobra.MinimumNArgs(1)确实可以确保我得到至少一个位置参数，但我找不到一种方法可以在帮助文档中显示它：

Error: requires at least 1 arg(s), only received 0
Usage:
  my-app stripe customers delete [flags]

Flags:
  -h, --help                    help for delete
  -k, --stripe-api-key string   The Stripe API key. [env: stripe_api_key]

有没有办法告诉 Cobra 在帮助中显示位置参数，例如：

Usage:
  my-app stripe customers delete [flags] customer_id [...customer_id]

现在，帮助文档对于向用户显示他们应该作为位置参数传递的内容并不是很有帮助。

将Use您的命令的字段设置为：

    deleteCustomerCommand = &cobra.Command{
        Use: "delete [flags] customer_id [...customer_id]",
        ...

可以在以下代码中找到如何使用它的完整详细信息cmd.UseLine()：
