Multi Window Output

Multi Window Output allows you to have multiple output screens in the same terminal screen. Each time Screen is updated, Screen empties its buffer and updates the terminal's screen with the Screen's content.

Screen

Start a new Screen with Screen::new(). You may set the screen's name with the set_name method. You may also set a window's name with the set_window_name method. The name of the Screen will be displayed at the top of the terminal. Each window's name will be displayed at the bottom of it. The id of the default window is 0.

let mut screen = Screen::new();

You can split the window into multiple windows. Call append_left_child(id) or append_down_child(id) methods to split a window with id vertically or horizontally.

let new_window_id = screen.append_left_child(0).unwrap();
let other_new_window_id = screen.append_down_child(0).unwrap();
let last_window_id = screen.append_left_child(new_window_id).unwrap();

To put content on to the screen you can use Screen::println(&mut screen, id, line), Screen::print(&mut screen, id, line), and Screen::flush(&mut screen, id).

// This will print a new line with "New Line" in the window with id new_window_id and refresh the screen.
screen.println(new_window, "New Line").unwrap();

// This will print a line with "Line" in the window with id new_window_id; however, it will not start a new line nor refresh the screen.
screen.print(new_window, "Line").unwrap();

// This will flush the current line and refresh the screen.
screen.flush(new_window).unwrap();

Bridge

Bridge allows you to call the content functions of Screen from different locations. This is especially useful when printing things from different threads. The only downside to using bridge, is that you can't append new children to the Screen you pass to Bridge::new(&screen).

To create a bridge.

let bridge = Bridge::new(screen);

To access bridge from multiple locations, use the Bridge::clone(&bridge) function.

let other_bridge = Bridge::clone(&bridge);

To put content in the Screen that you passed to create the Bridge, use Bridge::println(...), Bridge::print(...), and Bridge::flush(...). These work similarly to its Screen counter parts.

// Notice how you can call the println function from different variables
bridge.println(new_window, "New Line").unwrap();
other_bridge.println(new_window, "New New Line").unwrap();

Ideally, when you finish using a screen, run bridge.kill() to end the screening process.
