Examples

let mut cmder = Builder::default_config("eg")
    .begin_class("one", "") // a class
        .begin_class("two", "")
        .add_action("three", "", |_, _| ())
        .end_class()
    .end_class()
    .begin_class("hello", "").end_class()
    .into_commander().unwrap();

let v: Vec<_> = create_tree_completion_items(&cmder).into_iter().map(|x| x.completestr).collect();
assert_eq!(v, vec!["hello", "one", "one two", "one two three"]
    .into_iter().map(|x| x.to_string()).collect::<Vec<_>>());

cmder.parse_line("one", true, &mut std::io::sink());

let v: Vec<_> = create_tree_completion_items(&cmder).into_iter().map(|x| x.completestr).collect();
assert_eq!(v, vec!["two", "two three"]
    .into_iter().map(|x| x.to_string()).collect::<Vec<_>>());
