> Some single-line solution to avoid empty lines
> -----------------------------------------------
>
> 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.
