Subcommands Categories

For additional organization in apps that have many subcommands, you can associate a category for each command to group them together in the help output, e.g.:

package main

import (
    "log"
    "os"

    "github.com/urfave/cli/v2"
)

func main() {
    app := &cli.App{
        Commands: []*cli.Command{
            {
                Name: "noop",
            },
            {
                Name:     "add",
                Category: "template",
            },
            {
                Name:     "remove",
                Category: "template",
            },
        },
    }

    if err := app.Run(os.Args); err != nil {
        log.Fatal(err)
    }
}

Will include:

COMMANDS:
  noop

  template:
    add
    remove
