你如何在FreeMarker宏中调用函数？

Question

有没有办法在Freemarker宏中调用函数？ 我想要做的例子：

<#function foo>
  <return "hello">
</#function>

<#macro fooMacro>
  ${foo()}    
</#macro>

<@fooMacro> <#-- This doesn't work for me
                 "The "foo()" has evaluated to null or missing" -->

同样，有没有办法将函数的输出传递给宏的参数？像：

<#macro fooMacro p1>
   ${p1}
</#macro>

<@fooMacro p1=foo()/> <!-- Also doesn't seem to work for me -->

Answer 1

答案：两者都有可能，只需更改

<return "hello">  ==>  <#return "hello">
