Rushterm
Make your CLI app easy by adding menu. Create nested menus, navigate with hotkeys. Data-driven. No function/macro complexity.
Example
Firstly, we'll need to construct a Menu
instance with its Item
s. Bring them into scope. Menu
instance doesn't need to be mutable. Next, we'll invoke .run()
method on the instance to execute our menu:
use rushterm::{Item, Menu};
fn main() {
let menu = Menu {
name: "My Main Menu",
items: vec![
Item::Action {
name: "Action0",
hotkey: Some('a'),
exp: Some("Action0 Explanation. This Has Been Assigned To A Hotkey."),
},
Item::Action {
name: "Action1",
hotkey: None,
exp: Some("Action1 Explanation. This Has No Hotkey."),
},
Item::SubMenu {
name: "Submenu0",
hotkey: Some('s'),
exp: Some("Submenu0 explanation."),
items: vec![
Item::Action {
name: "Sub0 Action0",
hotkey: Some('a'),
exp: Some("Sub Action0 Explanation. This Has Been Assigned To A Hotkey."),
},
Item::SubMenu {
name: "Deepermenu0",
hotkey: Some('d'),
exp: Some("Deepermenu0 Explanation."),
items: vec![
Item::Action {
name: "Deeper Action0",
hotkey: Some('f'),
exp: None,
},
Item::Action {
name: "Deeper Action1",
hotkey: Some('g'),
exp: Some("Deeper Action1 Explanation."),
},
],
},
],
},
],
exp: Some("My Main Menu Explanation."),
esc: true,
};
let selection = menu.run();
dbg!(&selection);
}
If selection is successful, run()
method will return us Selection
type in Ok()
variant to get information we may need in ongoing execution. If not, exits the running with an Err()
variant.
