Subject [jira] [Created] (FREEMARKER-21) Reference to the object in condition - avoid repeating the same in #if and ${...}
Date Tue, 19 Apr 2016 19:18:25 GMT
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.
