Freemarker嵌套宏

Question

如何调用嵌套宏？

<@replaceA-sToB-s>
   <@replaceB-sToC-s Text/>
</@replaceA-sToB-s>

replaceB-sToC-s简单地将任何“B”替换为“C” replaceA-sToB-s简单地将任何“A”替换为“B”

Answer 1

如果您想将replaceB-sToC-s宏的结果传递给replaceA-sToB-s，那么您必须使用以下内容：

<#assign str><@replaceB-sToC-s "abc" /></#assign> 
<@replaceA-sToB-s str />

Answer 2

像这样：

<#macro replaceAsToBs>
  <#local captured><#nested></#local>
  ${captured?replace('a', 'b')}<#t>
</#macro>

<#macro replaceBsToCs text>
  ${text?replace('b', 'c')}<#t>
</#macro>

（#t - s仅用于移除${...}部分周围的额外空格。）然后您将其称为：

<@replaceAsToBs>
   <@replaceBsToCs "abcd"/>
</@replaceAsToBs>
