Thank you very much Nathan for clarifying what body content meant. At least now I know what it means, but I think I am having a problem with my trim function here. It seems to delete everything. I have no clue how this worked previously. To avoid naming conflicts, I decided to rename my macro. It now looks like: #macro(query_url $query_param) q=$query_param #end
#macro(my_trim)$!bodyContent.trim()#end I call it using #@my_trim()#query_url("sometext")#end And the result is blank i.e. I do not see anything in the result. I now attempt: #macro(my_trim)PREPEND$!bodyContent.trim()#end This time I see only: PREPEND This is expected, but why nothing from $!bodyContent.trim() I don't know what is happening to trim() function i.e. why it is not working. But thank you for answering my question. O. O. ----- Messaggio originale ----- Da: Nathan Bubna <nbu...@gmail.com> A: Velocity Users List <user@velocity.apache.org>; O.

Yes, all velocimacros have bodies in their definition: #macro( foo ) definition only #end #macro( bar ) definition accepts $bodyContent #end Not all velocimacros accept bodies in their usage: #foo() #@bar() body content when used #end Produces: definition only definition accepts body content when used As to why your example ends up with preceding spaces, i am not certain. The "format" part in particular, because Velocity has only input text and output text, no "format". Try defining your #@trim like so: #macro( trim )$!bodyContent.trim()#end to ensure there are no sneaky whitespaces hiding in the definition. On Mon, Aug 5, 2013 at 9:25 AM, O.
