3.18.2 Debugging dependencies

Use ?- debug(html(script)). to see the requested and final set of resources. All declared resources are in html_resource/3. The edit/1 command recognises the names of HTML resources.

[det]html_resource(+About, +Properties)

Register an HTML head resource. About is either an atom that specifies an HTTP location or a term Alias(Sub). This works similar to absolute_file_name/2. See http:location_path/2 for details. Recognised properties are:

requires(+Requirements)

Other required script and css files. If this is a plain file name, it is interpreted relative to the declared resource. Requirements can be a list, which is equivalent to multiple requires properties.

virtual(+Bool)

If true (default false), do not include About itself, but only its dependencies. This allows for defining an alias for one or more resources.

aggregate(+List)

States that About is an aggregate of the resources in List.

[det]html_requires(+ResourceOrList)//

Include ResourceOrList and all dependencies derived from it and add them to the HTML head using html_post/2. The actual dependencies are computed during the HTML output phase by html_insert_resource/3.
