+## Setup CardDAV client
+
+Sinusbot doesn't allow direct communication via DAV, so this client runs seperately.
+They communicate via `ws://127.0.0.1:23845`, so the DAV program has to run on the same host as Sinusbot.
+
+1. Download `ws-server.js` and `node_modules` into a seperate folder.
+```bash
+git clone https://github.com/subDesTagesMitExtraKaese/sinusbot-birthday-script/tree/dav-test
+cd sinusbot-birthday-script
+```
+
+2. Create `secrets.js` and enter your CardDAV server credentials.
+```javascript
+module.exports = {
+  davUrl:         'https://example.com/dav.php',
+  davUsername:    'username',
+  davPassword:    'password',
+  davAddressBook: ''
+}
+```
+
+3. install node.js
+```bash
+sudo apt update
+sudo apt upgrade -y
+sudo apt autoremove
+sudo apt install nodejs
+```
+
+4. test the program with sinusbot running
+```bash
+node ws-server.js
+```
+
+5. make it run on boot: create `/lib/systemd/system/sinusbot-birthday-sync.service`
+```

+
+  Generator based control flow goodness for nodejs and the browser,
+  using promises, letting you write non-blocking code in a nice-ish way.
+
+## Co v4
+
+  `co@4.0.0` has been released, which now relies on promises.
+  It is a stepping stone towards [ES7 async/await](https://github.com/lukehoban/ecmascript-asyncawait).
+  The primary API change is how `co()` is invoked.
+  Before, `co` returned a "thunk", which you then called with a callback and optional arguments.
+  Now, `co()` returns a promise.
+
+```js
+co(function* () {
+  var result = yield Promise.resolve(true);
+  return result;
+}).then(function (value) {
+  console.log(value);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+  If you want to convert a `co`-generator-function into a regular function that returns a promise,
+  you now use `co.wrap(fn*)`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```
+
+## Platform Compatibility
+
+  `co@4+` requires a `Promise` implementation.
+  For versions of node `< 0.11` and for many older browsers,
+  you should/must include your own `Promise` polyfill.
+
+  When using node 0.11.x or greater, you must use the `--harmony-generators`
+  flag or just `--harmony` to get access to generators.
+
+  When using node 0.10.x and lower or browsers without generator support,
+  you must use [gnode](https://github.com/TooTallNate/gnode) and/or [regenerator](http://facebook.github.io/regenerator/).
+
+  io.js is supported out of the box, you can use `co` without flags or polyfills.
+
+## Installation
+
+```
+$ npm install co
+```
+
+## Associated libraries
+
+Any library that returns promises work well with `co`.
+
+- [mz](https://github.com/normalize/mz) - wrap all of node's code libraries as promises.
+
+View the [wiki](https://github.com/visionmedia/co/wiki) for more libraries.
+
+## Examples
+
+```js
+var co = require('co');
+
+co(function *(){
+  // yield any promise
+  var result = yield Promise.resolve(true);
+}).catch(onerror);
+
+co(function *(){
+  // resolve multiple promises in parallel
+  var a = Promise.resolve(1);
+  var b = Promise.resolve(2);
+  var c = Promise.resolve(3);
+  var res = yield [a, b, c];
+  console.log(res);
+  // => [1, 2, 3]
+}).catch(onerror);
+
+// errors can be try/catched
+co(function *(){
+  try {
+    yield Promise.reject(new Error('boom'));
+  } catch (err) {
+    console.error(err.message); // "boom"
+ }
+}).catch(onerror);
+
+function onerror(err) {
+  // log any uncaught errors
+  // co will not throw any errors you do not handle!!!
+  // HANDLE ALL YOUR ERRORS!!!
+  console.error(err.stack);
+}
+```
+
+## Yieldables
+
+  The `yieldable` objects currently supported are:
+
+  - promises
+  - thunks (functions)
+  - array (parallel execution)
+  - objects (parallel execution)
+  - generators (delegation)
+  - generator functions (delegation)
+
+Nested `yieldable` objects are supported, meaning you can nest
+promises within objects within arrays, and so on!
+
+### Promises
+
+[Read more on promises!](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
+
+### Thunks
+
+Thunks are functions that only have a single argument, a callback.
+Thunk support only remains for backwards compatibility and may
+be removed in future versions of `co`.
+
+### Arrays
+
+`yield`ing an array will resolve all the `yieldables` in parallel.
+
+```js
+co(function* () {
+  var res = yield [
+    Promise.resolve(1),
+    Promise.resolve(2),
+    Promise.resolve(3),
+  ];
+  console.log(res); // => [1, 2, 3]
+}).catch(onerror);
+```
+
+### Objects
+
+Just like arrays, objects resolve all `yieldable`s in parallel.
+
+```js
+co(function* () {
+  var res = yield {
+    1: Promise.resolve(1),
+    2: Promise.resolve(2),
+  };
+  console.log(res); // => { 1: 1, 2: 2 }
+}).catch(onerror);
+```
+
+### Generators and Generator Functions
+
+Any generator or generator function you can pass into `co`
+can be yielded as well. This should generally be avoided
+as we should be moving towards spec-compliant `Promise`s instead.
+
+## API
+
+### co(fn*).then( val => )
+
+Returns a promise that resolves a generator, generator function,
+or any function that returns a generator.
+
+```js
+co(function* () {
+  return yield Promise.resolve(true);
+}).then(function (val) {
+  console.log(val);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+### var fn = co.wrap(fn*)
+
+Convert a generator into a regular function that returns a `Promise`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```

+# ws: a Node.js WebSocket library
+
+[![Version npm](https://img.shields.io/npm/v/ws.svg?logo=npm)](https://www.npmjs.com/package/ws)
+[![Build](https://img.shields.io/travis/websockets/ws/master.svg?logo=travis)](https://travis-ci.com/websockets/ws)
+[![Windows x86 Build](https://img.shields.io/appveyor/ci/lpinca/ws/master.svg?logo=appveyor)](https://ci.appveyor.com/project/lpinca/ws)
+[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg)](https://coveralls.io/github/websockets/ws)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+## Protocol support
+
+- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+- **HyBi drafts 13-17** (Current default, alternatively option
+  `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+  operations such as masking and unmasking the data payload of the WebSocket
+  frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+  message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
+utility functions.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+  port: 8080,
+  perMessageDeflate: {
+    zlibDeflateOptions: {
+      // See zlib defaults.
+      chunkSize: 1024,
+      memLevel: 7,
+      level: 3
+    },
+    zlibInflateOptions: {
+      chunkSize: 10 * 1024
+    },
+    // Other options settable:
+    clientNoContextTakeover: true, // Defaults to negotiated value.
+    serverNoContextTakeover: true, // Defaults to negotiated value.
+    serverMaxWindowBits: 10, // Defaults to negotiated value.
+    // Below options specified as default values.
+    concurrencyLimit: 10, // Limits zlib concurrency for perf.
+    threshold: 1024 // Size (in bytes) below which messages
+    // should not be compressed.
+  }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+  console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  const array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = https.createServer({
+  cert: fs.readFileSync('/path/to/cert.pem'),
+  key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+const url = require('url');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+  // ...
+});
+
+wss2.on('connection', function connection(ws) {
+  // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  const pathname = url.parse(request.url).pathname;
+
+  if (pathname === '/foo') {
+    wss1.handleUpgrade(request, socket, head, function done(ws) {
+      wss1.emit('connection', ws, request);
+    });
+  } else if (pathname === '/bar') {
+    wss2.handleUpgrade(request, socket, head, function done(ws) {
+      wss2.emit('connection', ws, request);
+    });
+  } else {
+    socket.destroy();
+  }
+});
+
+server.listen(8080);
+```
+
+### Client authentication
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss = new WebSocket.Server({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+  ws.on('message', function message(msg) {
+    console.log(`Received message ${msg} from user ${client}`);
+  });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+  // This function is not defined on purpose. Implement it with your own logic.
+  authenticate(request, (err, client) => {
+    if (err || !client) {
+      socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+      socket.destroy();
+      return;
+    }
+
+    wss.handleUpgrade(request, socket, head, function done(ws) {
+      wss.emit('connection', ws, request, client);
+    });
+  });
+});
+
+server.listen(8080);
+```
+
+Also see the provided [example][session-parse-example] using `express-session`.
+
+### Server broadcast
+
+A client WebSocket broadcasting to all connected WebSocket clients, including
+itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    wss.clients.forEach(function each(client) {
+      if (client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+

+
+### Use the Node.js streams API
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+const duplex = WebSocket.createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.pipe(process.stdout);
+process.stdin.pipe(duplex);
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+  const ip = req.socket.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+  const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+  this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.isAlive = true;
+  ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+  wss.clients.forEach(function each(ws) {
+    if (ws.isAlive === false) return ws.terminate();
+
+    ws.isAlive = false;
+    ws.ping(noop);
+  });
+}, 30000);
+
+wss.on('close', function close() {
+  clearInterval(interval);
+});
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+  clearTimeout(this.pingTimeout);
+
+  // Use `WebSocket#terminate()`, which immediately destroys the connection,
+  // instead of `WebSocket#close()`, which waits for the close timer.
+  // Delay should be equal to the interval at which your server
+  // sends out pings plus a conservative assumption of the latency.
+  this.pingTimeout = setTimeout(() => {
+    this.terminate();
+  }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+  clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+
+A JavaScript implementation of W3C DOM for Node.js, Rhino and the browser. Fully
+compatible with `W3C DOM level2`; and some compatible with `level3`. Supports
+`DOMParser` and `XMLSerializer` interface such as in browser.
+
+Install:
+-------
+>npm install xmldom
+
+Example:
+====
+```javascript
+var DOMParser = require('xmldom').DOMParser;
+var doc = new DOMParser().parseFromString(
+    '<xml xmlns="a" xmlns:c="./lite">\n'+
+        '\t<child>test</child>\n'+
+        '\t<child></child>\n'+
+        '\t<child/>\n'+
+    '</xml>'
+    ,'text/xml');
+doc.documentElement.setAttribute('x','y');
+doc.documentElement.setAttributeNS('./lite','c:x','y2');
+var nsAttr = doc.documentElement.getAttributeNS('./lite','x')
+console.info(nsAttr)
+console.info(doc)
+```
+API Reference
+=====
+
+ * [DOMParser](https://developer.mozilla.org/en/DOMParser):
+
+	```javascript
+	parseFromString(xmlsource,mimeType)
+	```
+	* **options extension** _by xmldom_(not BOM standard!!)
+
+	```javascript
+	//added the options argument
+	new DOMParser(options)
+	
+	//errorHandler is supported
+	new DOMParser({
+		/**
+		 * locator is always need for error position info
+		 */
+		locator:{},
+		/**
+		 * you can override the errorHandler for xml parser
+		 * @link http://www.saxproject.org/apidoc/org/xml/sax/ErrorHandler.html
+		 */
+		errorHandler:{warning:function(w){console.warn(w)},error:callback,fatalError:callback}
+		//only callback model
+		//errorHandler:function(level,msg){console.log(level,msg)}
+	})
