Feature: The todo app is backwards compatible with legacy subcommand parsing
  As a user of GLI
  My apps with subcommands should support the old, legacy way, by default

  Background:
    Given I have GLI installed
      And GLI's libs are in my path
      And my terminal size is "80x24"
      And todo_legacy's bin directory is in my path

  Scenario: Help completion mode for subcommands
    When I successfully run `todo help -c list`
    Then the output should contain:
    """
    contexts
    tasks
    """

  Scenario: Help completion mode partial match for subcommands
    When I successfully run `todo help -c list con`
    Then the output should contain:
    """
    contexts
    """

  Scenario Outline: Getting Help for a top level command of todo
    When I successfully run `todo <help_invocation>`
    Then the output should contain:

        list - List things, such as tasks or contexts

    SYNOPSIS
        todo [global options] list [command options] [--flag arg] [-x arg] [tasks]

    DESCRIPTION
        List a whole lot of things that you might be keeping track of in your
        overall todo list.

        This is your go-to place or finding all of the things that you might have
        stored in your todo databases. 

    COMMAND OPTIONS
        -l, --[no-]long - Show long form

    COMMANDS
        contexts - List contexts
        tasks    - List tasks (default)

    Examples:

      | help list       |
      | list -h         |
      | list --help     |

    DESCRIPTION
        Lists all of your tasks that you have, in varying orders, and all that
        stuff. Yes, this is long, but I need a long description.
