| Some experiments with using Groovy |
| |
| A) Some scripts that run against the Roller API |
| |
| examples/rollerapi/groovy - Runs Groovy with Roller jars in path. Edit it to set paths. |
| examples/rollerapi/roller-custom.properties - Database properties for bin/groovy |
| examples/rollerapi/listusers.gy - Lists users and roles in Roller system |
| examples/rollerapi/createuser.gy - Create a user |
| examples/rollerapi/createblog.gy - Create a blog |
| |
| |
| B) Some scripts that run against the Roller Admin Protocol |
| |
| examples/adminprotocol |
| |
| |
| C) A Roller GroovletRenderer that can evaluate a Roller template as Groovy code |
| with Groovlet-style "out" and "html" bindings. |
| |
| The implementation: |
| |
| org.apache.roller.scripting.GroovletRenderer |
| org.apache.roller.scripting.GroovletRendererFactory |
| org.apache.roller.scripting.GroovyRollerBinding |
| |
| Here's an example Hello World template: |
| |
| println "<html><body>Hello World</body></html>" |
| |
| Here's an example template that displays recent entries from a weblog: |
| |
| html.html { // html is implicitly bound to new MarkupBuilder(out) |
| head { |
| title(model.weblog.name) |
| } |
| body { |
| h1(model.weblog.name) |
| i(model.weblog.description) |
| map = model.getWeblogEntriesPager().getEntries(); |
| map.keySet().each() { |
| map.get(it).each() { |
| h2(it.title) |
| p(it.text) |
| br() |
| } |
| } |
| } |
| } |
| |
| D) A Roller GSPRenderer that can evaluate a Roller template as a Groovy Template |
| with GSP-style "out" and "html" bindings. |
| |
| The implementation: |
| |
| org.apache.roller.scripting.GSPRenderer |
| org.apache.roller.scripting.GSPRendererFactory |
| org.apache.roller.scripting.GSPRollerBinding |
| |
| Here's an example Hello World template: |
| |
| <html> |
| <body> |
| <%= "Hello World" %> |
| </body> |
| </html> |
| |
| Here's an example template that displays recent entries from a weblog: |
| |
| <html> |
| <head> |
| <title>${model.weblog.name}</title> |
| </head> |
| <body> |
| <h1>${model.weblog.name}</h1> |
| <i>${model.weblog.description}</i> |
| <% map = model.getWeblogEntriesPager().getEntries(); |
| map.keySet().each() { %> |
| <% map.get(it).each() { %> |
| <h2>${it.title}</h2> |
| <p>${it.text}</p><br /> |
| <% } |
| }%> |
| </body> |
| </html> |
| |
| |
| To use renderers (C) and (D) in Roller: |
| |
| 1) Put roller-groovy.jar and groovy-all-1.0.jar in WEB-INF/lib |
| |
| 3) In your roller-custom.properies file add this override: |
| |
| rendering.rollerRendererFactories=\ |
| org.apache.roller.ui.rendering.velocity.VelocityRendererFactory,\ |
| org.apache.roller.scripting.GroovletRendererFactory,\ |
| org.apache.roller.scripting.GSPRendererFactory,\ |
| |
| 4) Restart Roller |
| |
| 5) Create a new Weblog Page Template and set Template Language to either |
| "groovlet" or "gsp". |
| |
| 6) In your page template you'll have access to all normal Roller models |
| plus the name "out" will be bound to a Writer that you can use for output. |
| Also, the name "html" will be bound to a markup builder. |
