node-x11

X11 protocol client for Node.js: implements the core X11 protocol, as well as Xrender, Damage, Composite, Big-Requests, Dpms, Screensaver, XFixes, Shape, XTest, XC-Misc, GLX, and Apple-WM extensions.

Install

npm install x11

Windows users:

1. install XMing or Cygwin/X
2. get node-x11 copy (using git or from Github)

Example

Core requests usage:

/*
var nomnoml = require('nomnoml');
var src = '[nomnoml] is -> [awesome]';
console.log(nomnoml.renderSvg(src));
*/

var x11 = require('x11');

var Exposure = x11.eventMask.Exposure;
var PointerMotion = x11.eventMask.PointerMotion;

x11.createClient(function(err, display) {
  if (!err) {
    var X = display.client;
    var root = display.screen[0].root;
    var wid = X.AllocID();
    X.CreateWindow(
      wid,
      root, // new window id, parent
      0,
      0,
      500,
      500, // x, y, w, h
      0,
      0,
      0,
      0, // border, depth, class, visual
      { eventMask: Exposure | PointerMotion } // other parameters
    );
    X.MapWindow(wid);
    var gc = X.AllocID();
    X.CreateGC(gc, wid);
    var white = display.screen[0].white_pixel;
    var black = display.screen[0].black_pixel;
    cidBlack = X.AllocID();
    cidWhite = X.AllocID();
    X.CreateGC(cidBlack, wid, { foreground: black, background: white });
    X.CreateGC(cidWhite, wid, { foreground: white, background: black });
    X.on('event', function(ev) {
      if (ev.type == 12) {
        X.PolyFillRectangle(wid, cidWhite, [0, 0, 500, 500]);
        X.PolyText8(wid, cidBlack, 50, 50, ['Hello, Node.JS!']);
      }
    });
    X.on('error', function(e) {
      console.log(e);
    });
  } else {
    console.log(err);
  }
});

Server side (protocol + functionality) implementations for js + DOM

would be really great to make completely web based playground page, connecting node-x11 api to DOM based implementation
