Re: What does Velocimacro with a Body mean?
One trick I use when confronted with context objects that aren't behaving as
I'd expect is to output:
$object.class
and then it's clear what object type you're dealing with.

It does not work because bodyContent is an instance of the ASTNode class
and not a string, so it does not have the trim method.
Use something like this:
#macro(my_trim)#set($str=$bodyContent)$str.trim()#end
Test:
before#@my_trim()-blah- #{end}after
Renders:
before-blah-after

Re: What does Velocimacro with a Body mean?
Thank you very much Erik. (Great to see you here and on the Solr group.) This is a good tip, because from it I realized that bodyContent is class org.apache.velocity.runtime.directive.Block. So another way to trim from what Alex suggested is: #macro(my_trim)$!bodyContent.toString().trim()#end Simply doing: #macro(my_trim)$!bodyContent.trim()#end Does not work. Thanks again, O.

Thank you very much Nathan for clarifying what body content

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.

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.

I thought
all Velocimacros had bodies, just like all non-trivial functions in C or

have bodies. I attempted the use the above suggestion given in the URL

I attempted the following in my Global Library:
#macro(query_url $query_param)
q=$query_param

#macro(trim)
$!bodyContent.trim()
#end
According to the above URL, in my template, I called this
using:
#@trim()#query_url(sometext)#end
The result seems to be:
q=sometext
i.e. there are spaces in the front that I don't like.
(Depending on the format you are looking at, these preceeding spaces
might be
deleted, but they appear in the rendered results.) Any ideas what I am

wrong?
