Re: What does "Velocimacro with a Body" mean?

2013-08-07 Thread O. Olson


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.

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.

It should work, so debug it by testing everything:

--%<--

#macro(my_trim)$bodyContent becomes $!bodyContent.trim()#end

Just #qu: #query_url("sometext")

Trimmed: #@my_trim()#query_url("sometext")#end

-->%--

Re: What does "Velocimacro with a Body" mean?

2013-08-07 Thread Alex Fedotov
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

Thank you very much Sergiu  and Alex. 
 
    I was just
about to post to Sergiu that I could not get his suggestion to work, when I saw 
the post from Alex. 
 
Thank you Alex. You are totally
correct here – your suggestion worked perfectly and solved my problem.
 
Thanks again to both of you,

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

before-blah-after
