Wrangler CLI

Wrangler CLI is a trivial wrapper around github.com/spf13/cobra that allow one to define a simple struct with tags as a way to create cobra.Command objects. For example

package main

import (
    "fmt"

    "github.com/rancher/wrangler-cli"
    "github.com/spf13/cobra"
)

type App struct {
    OptionOne string `name:"custom-name" usage:"Takes an option""`
}

func (a *App) Run(cmd *cobra.Command, args []string) error {
    if len(args) == 0 {
        return cmd.Help()
    }
    fmt.Printf("Your option one %s and args: %v\n", a.OptionOne, args)
    return nil
}

func main() {
    root := cli.Command(&App{}, cobra.Command{
        Short: "Some short description",
        Long:"Some long description",
    })
    cli.Main(root)
}
