Re: inserting separator between lis

Something like this?

<#macro join delimiter = ", ">
  <#local input>
    <#nested>
  </#local>
  <#list input?split("\n") as line>
  <#if line?trim != "">
    ${line?trim}<#t>
     <#if line_has_next>
        ${delimiter}<#t>
     </#if>
   </#if>
  </#list>
</#macro>

<@join>
    a
b


               c
  d
</@join>

outputs

a, b, c,  d

(And, of course, the ?split built-in can use regular expressions to
split, so far trickier split/join situations could be handled than the
above example... )
