Upgrade from 0.4 to 0.5

WARNING

I workded on making the user API more convenient therefore I had to make some changes to the user API. The problem with 0.4 is that you need to pass a Screen to the modules: cursor(), color(), terminal().

In the new situation you only have to do this when working with raw or alternate screen. When you just want to perform actions like styling on the main screen you don't have to to pass in the Screen any more. This will look like the following:

1. Remove Screen from the function calls: cursor(), color(), terminal(), input()

old

let screen = Screen::default();

let color = color(&screen);
let cursor = cursor(&screen);
let input = input(&screen);
let terminal = terminal(&screen);
let crossterm = Crossterm::new(&screen);
let terminal = Terminal::new(&screen.stdout);
let cursor = TerminalCursor::new(&screen.stdout);
let color = TerminalColor::new(&screen.stdout);
let input = TerminalInput::new(&screen.stdout);

new

let color = color();
let cursor = cursor();
let input = input();
let terminal = terminal();
let crossterm = Crossterm::new();
let terminal = Terminal::new();
let cursor = TerminalCursor::new();
let color = TerminalColor::new();
let input = TerminalInput::new();

2. When working with alternate or raw screen.

When working with alternate and or raw screen you still have to provide a Screen instance since information of the alternate and raw screen is stored in it. When doing this, the actions of the module will be perfomed on the alternate screen. If you don't do this your actions will executed at the main screen.

use crossterm::cursor;
use crossterm::color;
use crossterm::input;
use crossterm::terminal;

let screen = Screen::default();

if let Ok(alternate) = screen.enable_alternate_modes(false) {
    let screen = alternate.screen;
    let color = color::from_screen(&screen);
    let cursor = cursor::from_screen(&screen);
    let input = input::from_screen(&screen);
    let terminal = terminal::from_screen(&screen);
    let crossterm = Crossterm::from_screen(&screen);
    
    let terminal = Terminal::from_output(&screen.stdout);
    let cursor = TerminalCursor::from_output(&screen.stdout);
    let color = TerminalColor::from_output(&screen.stdout);
    let input = TerminalInput::from_output(&screen.stdout);
}
