VT100.js

Player for VT100-Animations. Play & enjoy old school animations on your terminal.

Intro

VT100-Animations are files containing special escaped character sequences, that old VT100-Terminals recognize and render.

Every modern Terminal can emulate these behaviours, but "unfortunately" they are too fast for this goal.

VT100.js comes to the rescue.

Quickstart

Install

nmp -g install vt100

Enjoy

curl https://raw.githubusercontent.com/gr3p1p3/vt100/master/animations/blinkeyes.vt | vt100

or

You will find more animations hosted on official vt100 GitHub repository.

JS-API

You can use VT100.js not only as CLI, but for implement your own software too.

Example

This implement a simple TCP-Server that listens on a certain port and sends Animation to each connected client.

const net = require('net');
const Player = require('vt100');

const server = net.createServer(function onConnectedSocket(client) {
    console.log('Connected client from', client.remoteAddress);
    const p = Player('/path/to/file.vt',
        {clearBefore: false}) //need to deactivate default vt100's behaviour
        .on('data', function (data) {
            client.write(data); //send animation-data
        })
        .on('end', function () {
            client.write('\n\n\n\u001b[1000DHosted by @gr3p'); // send bye-message at begin of line
            client.destroy(); //destroy client-connection after animation is done
        });

    //handling error of disconnected clients
    client.on('error', function (error) {
        console.log('Error for', client.remoteAddress, error.message);
        p.destroy(); //destroy vt100-stream
    });
});

server.listen(23, '0.0.0.0', function () {
    console.log('Server was started!');
});
