Subject [jira] [Created] (FREEMARKER-23) <#t> documentation doesn't match actual behavior
Date Wed, 04 May 2016 20:23:12 GMT
Ondra Žižka created FREEMARKER-23:
-------------------------------------

             Summary: <#t> documentation doesn't match actual behavior
                 Key: FREEMARKER-23
                 URL: https://issues.apache.org/jira/browse/FREEMARKER-23
             Project: Apache Freemarker
          Issue Type: Bug
          Components: engine
    Affects Versions: 2.3.23
            Reporter: Ondra Žižka



The docs says at http://freemarker.org/docs/ref_directive_t.html

{quote}
The placement of these directives inside the line has no importance. That is, the effect will
be the same regardless if you put the directive at the beginning of the line, or at the end
of the line, or in the middle of the line.

However that's not true - this is treated differently:

{code}
    <#if pom.coords.version??>${i1}<version>${pom.coords.version}</version>${"\n"}</#if><#t><#--
Null if same as parent. -->
    <#if pom.coords.packaging??>${i1}<packaging>${pom.coords.packaging}</packaging>${"\n"}</#if><#t>
{code}

Result:
{code}
    <version>1.0</version>
    <packaging>jar</packaging>
{code}

Alternative:
{code}
    <#if pom.coords.version??>${i1}<version>${pom.coords.version}</version>${"\n"}<#t></#if><#--
Null if same as parent. -->
    <#if pom.coords.packaging??>${i1}<packaging>${pom.coords.packaging}</packaging>${"\n"}<#t></#if>
{code}

Result:
{code}
    <version>1.0</version>
    <packaging>jar</packaging>
{code}

BTW, the .23 and .24 are marked as unreleased here in jira.
