Live log mod

// Live log mod: a window built around ui.list, a list of lines that scrolls on its own.
// It keeps the newest 300 lines, follows the newest one unless you scroll up, and fills
// the window's free height, so the window itself never scrolls.

import { game, ui } from 'rednode';

const time = () => new Date().toLocaleTimeString();
const log = ui.list({ keep: 300 });
let lines = 0;
const count = ui.text('No lines yet.', { tone: 'dim' });

function add(text) {
  log.push(`${time()}  ${text}`);
  lines++;
  count.set({ text: `${lines} lines so far; the list keeps the newest 300.` });
}
