Call this to turn a textarea into an in-browser code editor using the CodeMirror editor.

In PHP code, call it like this:

$this->run (
    'admin/util/codemirror',
    array (
        'field_id' => 'body'
    )
);

In a view template, call it like this:

{! admin/util/codemirror?field_id=my_field !}

Alternately, you can disable the auto-initialization and call it manually on an element like this:

{! admin/util/codemirror?field_id=0 !}

<textarea id="edit-me"></textarea>

<script>
$(function () {
    var codemirror = CodeMirror.fromTextArea (
        document.getElementById ('my_field'),
        {
            mode: 'text/html',
            theme: 'default',
            lineNumbers: true
        }
    );
});
</script>

Additional parameters:

• mode - The editor mode for syntax highlighting (default = htmlmixed)
• theme - The color theme to use (default = elegant)
• lineWrapping - Whether to wrap lines (default = false)
