Macro crokey::key

macro_rules! key {
    ($($tt:tt)*) => { ... };
}

check and expand at compile-time the provided expression into a valid KeyCombination.

For example:

let key_event = key!(ctrl-c);

is expanded into (roughly):

let key_event = crokey::KeyCombination {
    modifiers: crossterm::event::KeyModifiers::CONTROL,
    codes: crokey::OneToThree::One(crossterm::event::KeyCode::Char('c')),
};

Keys which can’t be valid identifiers or digits in Rust must be put between simple quotes:

let ke = key!(shift-'?');
let ke = key!(alt-']');
