1. You must include the stylesheet lib/dhtmlxcalendar.css in your page
2. You must put everything in lib/img in the same directory that you put dhtmlxcalendar.css.
3. You must provide the lib/dhtmlxcalendar.js file in your page

After cloning the repo, you will need reflex-platform you can run git submodule update --init --recursive to get that code as a submodule.

You can then run nix-shell -A shells.ghc or nix-shell -A shells.ghcjs to get a wired up nix-shell. Alternatively you can cd reflex-dhtmlx-example and run nix-build ../ -A ghcjs.reflex-dhtmlx-example and simply open index.html in your browser.

You can also see the example here.

If you are to update the javascript blob in libs/dhtmlxcalendar.js, please follow these steps to update the exports for google closure compiler:

1. Find all instances of window.dhx and change them to window['dhx'].

2. Find all instances of window.dhx4 and change them to window['dhx4'].

3. Find all instances of window.dhtmlxEvent and change them to window['dhtmlxEvent'].

4. Find the definition of the dhtmlxEvent function - it should be inside an

   if(undefined...){ function dhtmlxEvent...

   and export dhtmlxEvent by adding window['dhtmlxEvent']=dhtmlxEvent; immediately after the function definition, inside the if statement.

Do this for any other symbols that may end up as undefined after running your program through google's closure compiler. https://developers.google.com/closure/compiler/docs/api-tutorial3#export
