Hi team,
I looked at Chris's modules in mod-db and thought about using them for
sitemap variable substitution.
Up to now, sitemap variables can only be set by matchers and actions,
and we thus have a number of them whose primary purpose is to populate
sitemap parameters. This includes e.g. RequestParamAction,
RequestHeaderMatcher, SessionAttributeMatcher, etc.
Now what about allowing the use of InputModules in sitemap variable
substitution ? For this, we need to extend the variable naming scheme :
if a variable name contains a colon (':'), the string before the colon
identifies an InputModule, and the string after the colon identifies an
attribute name for the InputModule (see InputModule.getAttribute())
So the following snippet (copied from RequestParamAction javadoc) :
<map:act type="request">
<map:parameter name="parameters" value="true"/>
<map:generate src="users/menu-{id}.xml">
</map:act>
could be written more simply :
<map:generate src="users/menu-{request-param:id}.xml"/>
The only problem with this extended syntax is that it may break actions
and matchers that return variables whose name contains a colon. AFAIK,
no such component currently exists in Cocoon.
Chris, what about passing the full object model instead of just the
Request to {Input, Output}Modules ? This would allow a wider range of
implementations.
Thoughts ?
