default 'app.commands' if one is not is supplied

[jare19]

I am having a hard time figuring out how to make one of my app.commands default when a command is not supplied at run time.
for example

...
app.Commands = []cli.command{
                       {
                        Name: "command that I want to be default"
			Usage:  "Does something",
			Action: runthedefaultcommand,
			Flags: []cli.Flag{
				cli.StringFlag{
					Name:   "something.something",
					Usage:  "stuff",
					EnvVar: "ENV_VAR",
				},
                          },
                      },
                      {
			Name:   "second optional command that overwrites default",
			Usage:  "Do something else",
			Action: runoptcommand,
			Flags: []cli.Flag{
				cli.StringFlag{
					Name:  "something.somethingelse",
					Usage: "stuff",
				},
                          },
                      },
...

Hi @jare19,

There isn't currently a way to default a subcommand, but you can set the fields on the App itself to have default behavior. Something like:

app.Action = runthedefaultcommand
app.Flags = []cli.Flag{
				cli.StringFlag{
					Name:   "something.something",
					Usage:  "stuff",
					EnvVar: "ENV_VAR",
				},
                          }

app.Commands = []cli.command{
                     {
			Name:   "second optional command that overwrites default",
			Usage:  "Do something else",
			Action: runoptcommand,
			Flags: []cli.Flag{
				cli.StringFlag{
					Name:  "something.somethingelse",
					Usage: "stuff",
				},
                          },
                      },

Just edited this in Github so it may not compile, but should hopefully point you in the right direction. Let me know if this helps!

@jszwedko I actually need this too, do you mind if I take a crack at it and send a (v2) PR?

@jare19 here's what I used as a workaround locally:

func DefaultCommand(name string) ActionFunc {
	return func(ctx *Context) error {
		return ctx.App.Command(name).Run(ctx)
	}
}

Given that this is from last year, I think I'm comfortable closing it 🙂 feel free to re-open / open a new issue / comment in support if there's still interest here!
