# 14. VTL 格式化问题 虽然在本指南中的VTL经常显示在新行中或者有空格，但是下面的VTL ``` #set( $imperial = ["Munetaka","Koreyasu","Hisakira","Morikune"] ) #foreach( $shogun in $imperial ) $shogun #end ``` 和下面的写法同样有效。 ``` Send me #set($foo = ["$10 and ","a cake"])#foreach($a in $foo)$a #end please. ``` Velocity的行为并不受空格的影响，前述的指令也可以写成： ``` Send me #set( $foo = ["$10 and ","a cake"] ) #foreach( $a in $foo ) $a #end please. ``` 或者 ``` Send me #set($foo = ["$10 and ","a cake"]) #foreach ($a in $foo )$a #end please. ``` 上面每种写法结果都一样。
