[xwiki-devs] Wiki Macro Bridge on 2.0M2 for Groovy (was Re: Macros and JavaScript working together (was Re: [DISCUSSION] XWiki Chart Api & Chart Macro))

On Tue, Aug 4, 2009 at 9:29 AM, Asiri Rathnayake &lt;asiri.rathnayake(a)gmail.com Thanks for reminding me about the Xwiki macro bridge. Looks great and is a big improvement over how things were done previously. Your message was timely as helped me answer one of my big questions about having groovy or clojure macros available on virtual-wiki setup: http://platform.xwiki.org/xwiki/bin/view/DevGuide/WikiMacroTutorial - Wiki macro authors need to have programming rights - Wiki macros can only be defined inside the main wiki, though they can be used throughout a farm I wrote my first macro-bridge macro (see attachment Main.TestMacroBridge.xar ) in groovy in preparation for my experiments with scripting in Clojure. The hardest thing was finding out that the name of "context" had changed to "xcontext" for groovy and other JSR-223 languages, whereas velocity (and WikiMacroTutorial) uses "context". This has been discussed on the lists ( http://markmail.org/message/o2trzrnv5xts6x6v ), and the WikiMacroTutorial needs updating to reflect the final status & naming-conventions. My macro is quite simple. but does a lot, taken from here: http://www.ibm.com/developerworks/java/library/j-pg05199/index.html Usage: {{weather_by_zip zip=92625 /}} Code: ............................... Objects of type XWiki.WikiMacroClass WikiMacroClass 0: weather_by_zip {{script language=groovy}} def rss = new XmlSlurper().parseText((" http://weather.yahooapis.com/forecastrss?p=" + xcontext.macro.params.zip).toURL().text) println rss.channel.title println "Sunrise: ${rss.channel.astronomy.@sunrise}" println "Sunset: ${rss.channel.astronomy.@sunset}" println "Currently:" println "\t" + rss.channel.item.condition.@date println "\t" + rss.channel.item.condition.@temp println "\t" + rss.channel.item.condition.@text {{/script}} Objects of type XWiki.WikiMacroParameterClass WikiMacroParameterClass 0: zip ............................... May be you can put it to test by trying to implement your chart macro ;) It would be more useful to offer all-new Exhibit<http://www.simile-widgets.org/exhibit/> functionality with tighter integration into the Xwiki back-end, e.g. having document/space and other Xwiki "model" information abstractly available to an Exhibit-based "view/controller" to provide a "faceted views" presentation of Xwiki documents and contents. FYI, My existing Exhibit integration with Xwiki demo: http://nielsmayer.com/xwiki/bin/view/Exhibit/Presidents4 (source: http://nielsmayer.com/xwiki/bin/download/Exhibit/Presidents4/Presidents4Pkg…) My main commitment right now is an experiment to see if I can get JSR223-supported Clojure scripting in Xwiki. This message didn't give me much hope of success right now ( http://groups.google.com/group/clojure/msg/ad811b69d448e3db ) but I'll give Clojure on Xwiki a try anyways, and revisit later if it's just a matter of getting more solid JSR223 support for Clojure as development progresses.
