Yes, this is all I needed. Didn't realize I could invoke it inline. Not sure how I missed that!

How do I get the velocity script to render the List<Block> properly?You could check the tutorial at http://rendering.xwiki.org/xwiki/bin/view/Main/ExtendingMacro (check the deployment at the end).I'm not having a problem invoking the macro in a wiki page. But sometimes I'd like to invoke it from within a larger velocity script. I.e. I can do this: {{mymacro param="hello"/}} But I'd also like to do this: {{velocity}} #set($words = ["Some", "velocity", "code"]) #foreach($word in $words) $word ## $services.mymacro($word) #end {{/velocity}} I didn't see anything in the deployment part of the tutorial about doing this.I was going to respond the following: ----- Your first use case is a macro while your second one isn't. The second use case is simply a programmatic service or API that you wish to expose. Macros are not supposed to return anything. To implement your second use case you'd create a Script Service component in java, see http://extensions.xwiki.org/xwiki/bin/view/Extension/Script+Module Now there's another possibility which is to: * call your macro using a groovy script. You'll need to look it up and call its execute method. This will return a List of Blocks * still in the groovy macro code, lookup a renderer and tell it to render the list of blocks. This is slightly more tricky and I don't see why you'd want to do this TBH. To help you further we'd need to know more about your specific use case. ----- But I just understood that you simply want to render the macro from inside your velocity script. So you'd just need to do this: {{velocity}} #set($words = ["Some", "velocity", "code"]) #foreach($word in $words) $word ## {{mymacro param="$word"/}} #end {{/velocity}} Hope it helps, -Vincent
