Alisdair McDiarmid 59662c01af vendor: Upgrade mitchellh/cli
Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.

We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.

Go CLI Library GoDoc

cli is a library for implementing powerful command-line interfaces in Go. cli is the library that powers the CLI for Packer, Serf, Consul, Vault, Terraform, and Nomad.

Features

  • Easy sub-command based CLIs: cli foo, cli bar, etc.

  • Support for nested subcommands such as cli foo bar.

  • Optional support for default subcommands so cli does something other than error.

  • Support for shell autocompletion of subcommands, flags, and arguments with callbacks in Go. You don't need to write any shell code.

  • Automatic help generation for listing subcommands

  • Automatic help flag recognition of -h, --help, etc.

  • Automatic version flag recognition of -v, --version.

  • Helpers for interacting with the terminal, such as outputting information, asking for input, etc. These are optional, you can always interact with the terminal however you choose.

  • Use of Go interfaces/types makes augmenting various parts of the library a piece of cake.

Example

Below is a simple example of creating and running a CLI

package main

import (
	"log"
	"os"

	"github.com/mitchellh/cli"
)

func main() {
	c := cli.NewCLI("app", "1.0.0")
	c.Args = os.Args[1:]
	c.Commands = map[string]cli.CommandFactory{
		"foo": fooCommandFactory,
		"bar": barCommandFactory,
	}

	exitStatus, err := c.Run()
	if err != nil {
		log.Println(err)
	}

	os.Exit(exitStatus)
}
