Re: Formatting Issue (Whitespace)

Hi Alexandre,

the workaround to omit stray whitespaces in the output is to use
comments spanning the EOL and whitespaces:

#macro( button $index )#*
  *##if( $menu.size() > $index )#*
    *##set( $buttontext = $menu.elementAt($index).alttext )#*
    *#<A HREF="${menu.elementAt($index).link}">#*
      *#<IMG SRC="${req.contextPath}/button_factory?#*
         *#textColor=FFFFFF&bgColor=${accentcolor}#*
         *#&text=${utils.escapeForURL($buttontext)}">#*
    *#</A>#*
  *##else#*
    *#&nbsp;<!-- empty button -->#*
  *##end#*
*##end

I know this is not vey pretty, but it works. I have posted a proposal
to fix this in velocity, but it has not reached a consensus (will it ever?).

P.S. I see that you are using a button factory, is this based on my code? 
Cheers!
     As I've stated somewhere in some list the past (turbine, velocity, other?),
     it is intended to be published, can someone take a lead on this to get it
     into jakarta or sourceforge? I could also do this if someone points me in
     the right direction (jakarta account?).
