DESCRIPTION ^

YUI::Loader is a tool for loading YUI assets within your application. Loader will either provide the URI/HTML to access http://yui.yahooapis.com directly, or you can cache assets locally or serve them from an exploded yui_x.x.x.zip dir.

METHODS ^

YUI::Loader->new_from_yui_host([ base => <base>, version => <version> ])

YUI::Loader->new_from_internet([ base => <base>, version => <version> ])

Return a new YUI::Loader object configured to fetch and/or serve assets from http://yui.yahooapis.com/<version>

YUI::Loader->new_from_yui_dir([ dir => <dir>, version => <version> ])

Return a new YUI::Loader object configured to fetch/serve assets from a local, exploded yui_x.x.x.zip dir

As an example, for a dir of ./assets, the reset.css asset should be available as:

    ./assets/reset/reset.css

YUI::Loader->new_from_uri([ base => <base> ])

Return a new YUI::Loader object configured to serve assets from an arbitrary uri

As an example, for a base of http://example.com/assets, the reset.css asset should be available as:

    http://example.com/assets/reset.css

YUI::Loader->new_from_dir([ dir => <dir> ])

Return a new YUI::Loader object configured to serve assets from an arbitrary dir

As an example, for a dir of ./assets, the reset.css asset should be available as:

cache_file( <component> )

Attempt to fetch a Path::Class::File for <component> using the current filter setting of the loader (-min, -debug, etc.) from the cache

source_uri( <component> )

Attempt to fetch a URI for <component> using the current filter setting of the loader (-min, -debug, etc.) from the source

html

Generate and return a string containing HTML describing how to include components. For example, you can use this in the <head> section of a web page.

If the loader has a cache, then it will attempt to generate URIs from the cache, otherwise it will use the source.

Here is an example:

    <link rel="stylesheet" href="http://example.com/assets/reset.css" type="text/css"/>
    <link rel="stylesheet" href="http://example.com/assets/fonts.css" type="text/css"/>
    <link rel="stylesheet" href="http://example.com/assets/base.css" type="text/css"/>
    <script src="http://example.com/assets/yahoo.js" type="text/javascript"></script>
    <script src="http://example.com/assets/dom.js" type="text/javascript"></script>
    <script src="http://example.com/assets/event.js" type="text/javascript"></script>
    <script src="http://example.com/assets/logger.js" type="text/javascript"></script>
    <script src="http://example.com/assets/yuitest.js" type="text/javascript"></script>

source_html

Generate and return a string containing HTML describing how to include components. For example, you can use this in the <head> section of a web page.

Here is an example:

    <link rel="stylesheet" href="http://example.com/assets/reset.css" type="text/css"/>
    <link rel="stylesheet" href="http://example.com/assets/fonts.css" type="text/css"/>
    <link rel="stylesheet" href="http://example.com/assets/base.css" type="text/css"/>
    <script src="http://example.com/assets/yahoo.js" type="text/javascript"></script>
    <script src="http://example.com/assets/dom.js" type="text/javascript"></script>
    <script src="http://example.com/assets/event.js" type="text/javascript"></script>
    <script src="http://example.com/assets/logger.js" type="text/javascript"></script>
    <script src="http://example.com/assets/yuitest.js" type="text/javascript"></script>
