(Quick Reference) ## external ### Purpose Renders the appropriate HTML linking markup for an external resource such as a CSS file, a JavaScript file, or a favicon. This is a convenience that takes the boilerplate out of the often verbose `<link>` and `<script>` tags, with auto-sensing of file types. This tag is aware of the Resources plugin, and if it’s installed it will correctly generate links to static resources processed by the plugin. ### Examples Example usages for the "shop" app:
    <g:external dir="css" file="main.css" />
    Output: <link href="/shop/css/main.css" type="text/css"
                  rel="stylesheet" media="screen, projector"/>

    <g:external uri="/images/icons/favicon.ico"/>
    Output: <link href="/shop/images/icons/favicon.ico" rel="favicon"/>

    <g:external uri="/images/icons/favicon.png"/>
    Output: <link href="/shop/images/icons/favicon.gif" rel="favicon"/>

    <g:external dir="images/icons" file="iphone.png" type="appleicon"/>
    Output: <link href="/shop/images/icons/favicon.gif" rel="apple-touch-icon"/>

Defaults to "" or path to the plugin for a plugin view or template. `dir` (optional) - the name of the directory containing the resource `file` (optional) - the name of the resource file `absolute` (optional) - If `true` will prefix the link target address with the value of the `grails.serverURL` property from `application.groovy`, or http://localhost:<port>; if there is no setting in `application.groovy` and not running in production. `plugin` (optional) - The plugin to look for the resource in `type` (optional) - The type of the link. Normally this is auto-detected by file extension, but you can override it. Each type name has an associated set of default attributes and tag type. `uri` (optional) - The app-relative URI of the resource, as an alternative to dir/file Any extra attributes supplied will override values provided as a default for the type.
