    <h1>Basic Observables/Dependencies</h1>
    <p>This is an example of a basic document using the document-eden library</p>
    <p>We can define an observable £a = 6£.</p>
    <p>Click the blue underlined value of a to change it</p>
    <script type="text/jseden">
      b is a * 10;
    </script>
    <p>Ten times that observable is £b£.</p>
    <hr>
    <h1>Changing attributes in HTML</h1>
    <p>Observables can change the value of any HTML element, by changing the content or the attributes: £fontsize=40£</p>
    <p>If you need to change the attribute, remember to add a <code>data-query</code> attribute to the tag.</p>
    <p style="font-size:£fontsize£px" data-query>This is size £fontsize£px</p>
    <hr>
    <h1>Changing attributes in SVG</h1>
    <p>You can change the values of the £colour=red£ square</p>
    <p>Idea - add some UI for options for the colour instead of typing it - maybe even a colour picker?!</p>
    <div>
      <p>rx: £rx=50£, ry: £ry=50£</p>
      <p>rWidth: £rWidth=50£, rHeight: £rHeight=50£</p>
    </div>
    <svg width="100%" height="200" xmlns="http://www.w3.org/2000/svg">
      <rect width="£rWidth£" height="£rHeight£" x="£rx£" y="£ry£" fill="£colour£" data-query/>
    </svg>
    <hr>
    <h1>JS-Eden Canvas</h1>
    <p>Or you can use a JS-Eden style canvas (looks exactly the same, but added black border to definition just to show a difference!):</p>
    <script type="text/jseden">
      r is Rectangle(rx,ry,rWidth,rHeight,colour, "black");
      picture is [r];
      view_picture_height = 200;
      view_picture_width = 400;
    </script>
    <div class="eden-picture" data-observable="picture">

    </div>
    <p>See the source of this page to set canvas size - <code>view_picture_height</code> and <code>view_picture_width</code>.</p>
    <hr>
    <h1>Actions</h1>
    <p>Actions can be named (see the source code of this bit)</p>
    <script type="text/jseden" data-action="changecolour">
      action changeRectangle{
        colour = nextColour;
      }
      nextColour is "red" if colour == "green" else "green";
    </script>
    <p>An action can contain an action (a tab in JS-Eden is an action).</p>
    <p>Can link an action to a button like this (will change the above rectangle colour to £nextColour£):</p>
    <button class="runAction" data-action="changecolour > changeRectangle">changeRectangle</button>
    <p>Could also script it from JS as <code>DocumentEden.runAction(actionName);</code></p>
    <hr>
    <h1>Saving/Reloading State</h1>
    <p>Might be appropriate to move between different 'phases' - allowing for definitions before and after a particular action has taken place</p>
    <p>Could save lots of different states in a JS object, then reload particular ones</p>
    <p>Message: £c£</p>
    <script type="text/jseden" data-action="states">
      c = "Before stateA";
      action stateA{
        c = "After stateA";
      }
    </script>
    <script>
      let savedState;

      function stateDemo(){
        savedState = DocumentEden.saveState();
      }
      function loadState(){
        DocumentEden.loadState(savedState, 1);
      }
    </script>
    <button onclick="stateDemo()">save state</button>
    <button class="runAction" data-action="states > stateA">do state A</button>
    <button onclick="loadState()">restore state</button>
    <hr>
    <h1>Using JSEden plugins</h1>
    <p>Plugins can be embedded, e.g. a script view</p>
    <script>
      window.allReady.then(
        ()=>{
          let scriptView = edenUI.createEmbedded("mysi", "ScriptInput", "script1", this);
          root.lookup("view_mysi_tabs").assign(["> states"],root.scope,EdenSymbol.jsAgent);
          root.lookup("view_mysi_current").assign(0,root.scope,EdenSymbol.jsAgent);
          root.lookup("view_mysi_height").assign(300,root.scope,EdenSymbol.jsAgent);
          root.lookup("view_mysi_width").assign(500,root.scope,EdenSymbol.jsAgent);
          root.lookup("view_mysi_showtabs").assign(true,root.scope,EdenSymbol.jsAgent);
          root.lookup("view_mysi_showbuttons").assign(true,root.scope,EdenSymbol.jsAgent);

          document.getElementById("myscript").appendChild(scriptView.contents[0]);
        }
      );
    </script>
    <div id="myscript" style="position:relative; height: 300px">
    </div>
  </body>
</html>
