  • Support to `<context>:<command>` style

    Support to `:` style

    Hey, it's just a suggestion which I can contribute on to create it

    Particularly, I like a lot heroku's command style <context>:<command> and I looked at that acmd doens't has support to put : as caracter in a command. What do you think about starting to accept : caracter to contemple this suggestion?

    🎈 I know that already exists support to put subcommand (congrats for this) but I would like to support <context>:<command> as command for example app:create or user:delete

    Failed with example

    Tried to make example with acmd, but have no success.

    package main

import (
	"context"
	"fmt"
	"github.com/cristalhq/acmd"
	"os"
)

func main() {
	cmds := []acmd.Command{
		{
			Name:        "test",
			Description: "test cmd",
			Do: func(ctx context.Context, args []string) error {
				fmt.Println("test")
				return nil
			},
		},
	}

	r := acmd.RunnerOf(cmds, acmd.Config{
		AppName:        "test",
		AppDescription: "Test example",
		Version:        "v0.0.1",
		Output: os.Stdout,
		Args: os.Args,
	})

	if err := r.Run(); err != nil {
		panic(err)
	}

}

    Build with go build main.go. All attempts to exec the command are failed with panic panic: acmd: cannot run command: no such command "./main".
