Description

Inspired by VELOCITY-583 (BlockMacro support) I implemented the same functionality in a slightly different way.

The new syntax is:

#@yourMacroName($arg1 $arg2) any valid velocity AST here #end

so basically the syntax is exactly the same as for normal macros except you put that @ prefix to the macro name. That tells Velocity that there's a macro AST body that should be passed to the actual macro.

And in the macro you can refer to the passed body 0-N times. Like:

#macro(yourMacroName $foo $bar)
$bodyContent
#end
