reflex-dom-th

Do you develop for the web? And you know functional reactive programming is the way to go. So you must use Reflex-DOM. But how can you integrate all these HTML snippet, which you found. You are tired in converting everything to to el, elAttr' etc, right?

From this day on this reflex-dom-th library will automate the task of converting your HTML templates to Reflex-Dom.

Examples

The basic example

[dom|<div>hello</div>|]

is equivalent to

el "div" $ text "hello"

You can also put the html in a external file and include it with

$(domFile "template.html")

It it possible to have multiple elements and attributes

[dom|<ul class="list">
       <li>Item1</div>
       <li>Item1</div>
     </ul> |]

Dynamic content can be injected between two curly braces. It will reference an unbound variable. It is not a haskell expression. Keeping haskell out of the template will give you better error messages.

[dom|<ul class="list">
      <li>{{item1}}</div>
      <li>{{item2}}</div>
    </ul> |]
  where item1, item2 :: MonadWidget t m =>  m ()
        item1 = text "Item1"
        item2 = text "Item2"

It is also possible to bind additionally a `Dynamic t (Map Text Text)' to the attributes

divWithAttrs :: MonadWidget t m => Dynamic t (Map Text Text) -> m ()
divWithAttrs dynAttrs = [dom|<div class="list" {{attr}}></div> |]

To bind events to the elements it is possible to extract get the elements as a result. The reference number is the position in the result tuple.

(li1, li2, ul, w) <- [dom|<ul #2 class="list">
                           <li #0>Item1</div>
                           <li #1>Item1</div>
	                   <li>{{widget #3}}</div>
                          </ul> |]
