Description:

malison

Malison is a small Dart library for drawing old school ASCII terminals in
the browser. I harvested it from my roguelike game, Hauberk and it's aimed
primarily at web games ASCII graphics. Think of it like curses for the web.
Using it #
Add it to your package's pubspec:
dependencies:
malison: any
copied to clipboard
Then use the library:
import 'dart:html';

import 'package:malison/malison.dart';

void main() {
// Create or query a <canvas> element to bind it to.
var canvas = new CanvasElement();
document.body.children.add(canvas);

// Create a new terminal. CanvasTerminal uses your browser's fonts.
// RetroTerminal uses a built in DOS-style Code Page 437 font.
var terminal = new RetroTerminal.dos(80, 40, canvas);

// You can draw strings at given positions.
terminal.writeAt(0, 0, "This is a terminal!");

// You can control the foreground and background color.
terminal.writeAt(0, 1, "This is blue on green", Color.blue, Color.green);

// You can also draw individual glyphs -- character+color units.
terminal.drawGlyph(3, 4, new Glyph.fromCharCode(CharCode.blackHeartSuit,
Color.red, Color.white));

// When you're done drawing, tell it to render all of the changes. It renders
// in batches for performance.
terminal.render();
