How do I build nested subcommands using cobra in Go?

Cobra is a powerful library for creating CLI applications in Go. One of its features is the ability to create nested subcommands, allowing for a more organized and hierarchical command structure. Below is an example of how to build nested subcommands using Cobra.


    package main

    import (
        "fmt"
        "github.com/spf13/cobra"
        "os"
    )

    func main() {
        var rootCmd = &cobra.Command{
            Use:   "app",
            Short: "A root command",
        }

        var subCmd1 = &cobra.Command{
            Use:   "sub1",
            Short: "First subcommand",
            Run: func(cmd *cobra.Command, args []string) {
                fmt.Println("Executing sub1 command")
            },
        }

        var subCmd1_1 = &cobra.Command{
            Use:   "sub1_1",
            Short: "First nested subcommand",
            Run: func(cmd *cobra.Command, args []string) {
                fmt.Println("Executing sub1_1 command")
            },
        }

        var subCmd2 = &cobra.Command{
            Use:   "sub2",
            Short: "Second subcommand",
            Run: func(cmd *cobra.Command, args []string) {
                fmt.Println("Executing sub2 command")
            },
        }

        // Nesting the commands
        rootCmd.AddCommand(subCmd1)
        subCmd1.AddCommand(subCmd1_1)
        rootCmd.AddCommand(subCmd2)

        // Execute the root command
        if err := rootCmd.Execute(); err != nil {
            fmt.Println(err)
            os.Exit(1)
        }
    }
