-------------------------------------

             Summary: A directive to print a new line
                 Key: FREEMARKER-20
                 URL: https://issues.apache.org/jira/browse/FREEMARKER-20
             Project: Apache Freemarker
          Issue Type: Bug
          Components: engine
    Affects Versions: 2.3.23
            Reporter: Ondra Žižka


I'd like to be able to generate a line conditionally, with 1 line of template source code.
{code}
            <#if dep.classifier??><classifier>${dep.classifier}</classifier></#if>
{code}

I haven't found a way. {{#t}} and {{#rt}} and {{#lt}} apply at compile time, so they don't
care about the condition. So they strip even if the content is there, which I don't want.

I could do this:
{code}
            <#if dep.classifier??><classifier>${dep.classifier}</classifier><#br></#if><#rt>
{code}

So that's the request. It can also be anything what helps me achieve that.

Until then, I have to do:
{code}
            <#if dep.classifier??>
            <classifier>${dep.classifier}</classifier>
            </#if>
{code}
Which I don't like because it makes the templates way longer.

Or
{code}
            <#if dep.classifier??><classifier>${dep.classifier}</classifier>
            </#if><#if dep.classifier??><classifier>${dep.classifier}</classifier>
            </#if>
            ...
{code}
Which I don't like because it's messy.
