Expected Behavior

I have to work with the famous Apache Freemarker template engine now. Freemarker Template Language (.ftl) seems not to be supported right now by Rainbow brackets. https://freemarker.apache.org/docs/ref_directives.html

The directives there are similar like HTML but with a hash char: <#if>…</#if> But there are directives, which don't need closing tags... like <#ftl...>, <#import ...>, <#assign ...>

Code snippet for test

<#if x == 1>
  x is 1
</#if>

<#if x == 1>
  x is 1
<#else>
  x is not 1
</#if>

<#if x == 1>
  x is 1
<#elseif x == 2>
  x is 2
<#elseif x == 3>
  x is 3
<#elseif x == 4>
  x is 4
<#else>
  x is not 1 nor 2 nor 3 nor 4
</#if>

not allowed: <#if>…<#else>...<#else>...</#if>

<#import "/libs/commons.ftl" as com>

<#ftl encoding="UTF-8">

i.e. assign

<#assign seq = ["foo", "bar", "baz"]>

<#macro myMacro>foo</#macro>
<#assign x>
  <#list 1..3 as n>
    ${n} <@myMacro />
  </#list>
</#assign>
Number of words: ${x?word_list?size}
${x}
