Let your users execute and play with the CoffeeScript and JavaScript in your documentation

See our messenger documentation for an example: http://hubspot.github.com/messenger/

<!-- You should already have jQuery included -->

<!-- Code Mirror is used to make the code blocks editable -->
<script type="text/javascript" src="lib/CodeMirror/codemirror.js"></script>

<!-- Include the CodeMirror languages you're going to use -->
<script type="text/javascript" src="lib/CodeMirror/mode/coffeescript/coffeescript.js"></script>
<script type="text/javascript" src="lib/coffee-script.js"></script>

<script type="text/javascript" src="build/js/executr.js"></script>

The code blocks you wish to be executable should be wrapped in <code executable></code>.

Run $.executr on the container of multiple code elements, the body, or a single code block.

The blocks will be converted into CodeMirror Editors, and a run button will be added. If you're not interested in the code being editable, take a look at the v1.1 tag.

Only the text (not tags) in the block will be executed, feel free to wrap your already-syntax-highlighted code.

The code editor will assume the height + 10px and width of the code element.

<pre><code executable>
$ ->
  alert "Testing!"
</code></pre>

$(function(){
  $('body').executr();
});

You can also make javascript executable, by either adding a data-type="javascript" attribute to the code block, or by adding defaultType: 'javascript' to the executr call.

<code data-type="javascript" executable>
alert("Testing!");
</code>

$.executr can be passed the following options

{
    codeSelector: 'code[executable]' # The jQuery selector items to be bound must match

    outputTo: 'div.output' # An element which should receive the output.
    appendOutput: true # Whether output should replace the contents of outputTo, or append to it

    defaultType: 'coffeescript' # The default source languange, if not supplied as a data-type attribute
    coffeeOptions: {} # Extra options for the CoffeeScript compiler

    codeMirrorOptions: {} # Extra options for CodeMirror

    setUp: -> # Code to run before each code block
    tearDown: -> # Code to run after each code block
}

Executr will fire two events on the element it is bound to:

• executrBeforeExecute(code string, normalized code language, executr options)
• executrAfterExecute(code output, code string, normalized code language, executr options)

You can build the project by running ./build.sh. It requires the CoffeeScript compiler.
