I don't know of something exists, but here is a reasonably simple solution:
Create a "meta" component that that collects the values and injects
them at the top of the head element at the end of the rendering
process.
The following code was compiled and briefly tested in 5.2.5. It
collects the values and injects them in the top of the head. You can
actually put this component anywhere in your template and the values
will go into the head.
Usage:
<t:meta content="IE=8" httpequiv="X-UA-Compatible"></t:meta>
<t:meta name="literal:keywords" content="literal:Hello Kitty"/>
Component:
public class Meta {
@Parameter(defaultPrefix = "literal")
private String content;
@Parameter(defaultPrefix = "literal")
private String httpEquiv;
@Parameter(defaultPrefix = "literal")
private String name;
@Parameter(defaultPrefix = "literal")
private String scheme;
@Environmental
private MetaSupport metaSupport;
@SetupRender
boolean storeMeta() {
metaSupport.addMeta("content", content, "http-equiv",
httpEquiv, "name", name, "scheme", scheme);
// don't render it now
return false;
}
}
Service Interface
public interface MetaSupport {
public void updateDocument(Document document);
void addMeta(String... fields);
}
Service Implementation
public class MetaSupportImpl implements MetaSupport {
private List<String[]> tags = new ArrayList<String[]>();
@Override
public void updateDocument(Document document) {
final Element head = document.find("html/head");
if (head == null) throw new RuntimeException("Meta requires a
head element");
int i = 0;
for (String[] tag : tags) {
head.elementAt(i++, "meta", tag);
}
}
@Override
public void addMeta(String... fields) {
if (fields.length % 2 != 0) throw new RuntimeException("Invalid meta!");
tags.add(fields);
}
}
Code for AppModule
@Contribute(MarkupRenderer.class)
public static void addMetaRenderFilter(
OrderedConfiguration<MarkupRendererFilter> configuration,
final Environment environment
) {
MarkupRendererFilter rendererFilter = new MarkupRendererFilter() {
public void renderMarkup(MarkupWriter writer,
MarkupRenderer renderer) {
MetaSupport metaSupport = new MetaSupportImpl();
environment.push(MetaSupport.class, metaSupport);
renderer.renderMarkup(writer);
environment.pop(MetaSupport.class);
metaSupport.updateDocument(writer.getDocument());
}
};
configuration.add("meta", rendererFilter, "before:*");
}
