Freemarker assigning escaped ${expression} to a variable












0














I need to assign an escaped ${expression} to a variable in Freemarker



From the question here, it's clear that we can escape the $ sign in this way



${r"${expression}"}


This works perfectly outside Freemarker context, but doesnot working inside. I am trying to do



<#assign x = "${r"${expression}"}">


But getting the following error:



Template inclusion failed:
You can't use "${" here as you are already in FreeMarker-expression-mode. Thus, instead of ${myExpression}, just write myExpression. (${...} is only needed where otherwise static text is expected, i.e, outside FreeMarker tags and ${...}-s.)



What is the way to achieve this? Thanks in advance.

          I had to spent some time to figure out the following scenarios to escape ${expression} -




          • In Freemarker assignment:



          <#assign var = r"${expression}">





          • In html attribute:



          <a href="/user/${r"${expression}"}"> Some link </a>





          • In Freemarker concatenation:



          <#assign x = "something&"+r"${expression}"/>
