[jira] [Created] (FREEMARKER-21) Reference to the object in
condition - avoid repeating the same in #if and ${...}
Ondra Žižka created FREEMARKER-21:
-------------------------------------
Summary: Reference to the object in condition - avoid repeating the same in #if and ${...}
Key: FREEMARKER-21
URL: https://issues.apache.org/jira/browse/FREEMARKER-21
Project: Apache Freemarker
Issue Type: New Feature
Components: engine
Reporter: Ondra Žižka
Fix For: 2.3.23
Repeating stuff is annoying, especially in programming.
Therefore this is annoying:
{code}
<#if someVariable.someMethod.someProperty??>
<div>${someVariable.someMethod.someProperty}</div>
</#if>
{code}
This would be better:
{code}
<#if someVariable.someMethod.someProperty?? as value>
<div>${value}</div>
</#if>
{code}
Not talking about the fact that it could only be evaluated once.
