SiteMesh module

The SiteMesh module integrates the SiteMesh 3 decoration and Web application integration framework with Magnolia. If you intend to use SiteMesh only as the mechanism for dynamic page caching you can skip this page after its installation and continue with Advanced Dynamic Page Caching.

SiteMesh intercepts requests to any static or dynamically generated HTML page requested through the web-server, processes the content and then merges it with one or more decorators to build the final result." – SiteMesh 3

Installing

Uninstalling

1. Remove the /server/filters/sitemesh node.
2. Remove the /server/rendering/engine/listeners/sitemesh node.
3. Remove the /modules/sitemesh node and its subnodes
4. Shut down Magnolia, remove the SiteMesh module JAR (magnolia-module-sitemesh.jar) from WEB-INF/lib and start up Magnolia again.

Filter

SiteMesh filter processes by default only text/html but can be configured to process any text resources such as css or javascript:

Decorators

The decorator contains the common layout and style that should be applied to the pages in the web application". – Getting Started with SiteMesh 3

If you have samples and demo/project installed, you can find SiteMesh sample under /demo-features/modules/sitemesh-sample.html and its decorator under /demo-features/modules/sitemesh-sample/decorator.html. You can configure more that one decorator per path (and of course use regular expression for path). You can find the templates under templates:/sitemesh-sample.

Decorator selector chooses the decorators for pages. MetaTagBasedDecoratorSelector is used by default.

Content processor

Processes the text content tag by tag. You can configure sets of rules under tagRuleBundles. You can use the bundles provided by SiteMesh 3.0.0. Just use info.magnolia.sitemesh.content.TagRuleBundleWrapper as class, create node wrapped and set the bundle class as the property class:

Tag rule bundles

Because the bundles provided by SiteMesh 3 are fixed sets of rules, Magnolia offers you also configurable info.magnolia.sitemesh.content.MagnoliaTagRuleBundle. You can dynamically add info.magnolia.sitemesh.content.MagnoliaRules to this bundle:

Set /server/filters/sitemesh/decoratedFilter/contentProcessor/tagRuleBundles/magnolia/rules/InjectUriRule/tag/baseUrl to http://localhost:8080${contextPath}, for example. 

• Request: https://demo.magnolia-cms.com/.
• Fragment request: https://localhost:8080/magnoliaPublic~mgnlArea=main~.

 Site-specific configurations are not taken into account.

If baseURL is not set, the base URL of the current request is used:

• Request: https://demo.magnolia-cms.com/.
• Fragment request: https://demopublic.magnolia-cms.com/~mgnlArea=main~.

Rules & Tags 

Every info.magnolia.sitemesh.content.MagnoliaRule holds tag. info.magnolia.sitemesh.content.AbstractTag processes a html tag. You can implement for example  a tag which replaces all occurrences of <b> with <s>. Set  includeInContent=true on rule if you don't want to replace the original tag but only append new content after it. Add content node named tagTypes to a tag to tell which tag types you want to process. All types (open, close, ...) will be processed if no tagTypes node will be added.

Fragment Injection Listener

Samples

The SiteMesh sample contains two preconfigured dynamic components for Standard Templating Kit:

• /modules/multisite/config/sites/default/templates/prototype/areas/branding/areas/metaNavigation/fragmentDefinition
• /modules/commenting/templates/components/comments/fragmentDefinition

Set /modules/multisite/config/sites/default/templates/prototype/areas/branding/areas/metaNavigation/fragmentDefinition=true, disable SiteMesh filter (/server/filters/sitemesh@enabled=false) and open a demo-project page to see the result of the sitemesh fragment injection listener: 

...a static page content before the dynamic component...
<mgnl:injecturi target="/demo-project/about~mgnlArea=branding,metaNavigation~" X-Magnolia-Cache="ttlValue=-1,CacheKeyGenerator=info.magnolia.sitemesh.samples.MetaNavigationCacheKeyGenerator,">
an dynamic meta navigation area
</mgnl:injecturi>
...a static page content after the dynamic component...

External fragment

There is the trivial sample for external fragment inclusion:

• component: config:modules/sitemesh/templates/components/externalFragment
• dialog: config:modules/sitemesh/dialogs/externalFragment
• availability: config:modules/standard-templating-kit/templates/pages/stkSection/areas/main/areas/opener/availableComponents/externalFragment
• template: templates:sitemesh-sample/externalFragment

Go to website/demo-project/about, delete the opener teaser component and add External Fragment instead. Add URL of a page which you want to render.
