Sergiu Dumitriu commented on VELOCITY-792:
------------------------------------------
I don't think this should be fixed globally. In some output types whitespace is
critical (think Python).
What we did inside XWiki was to write a filtering pre-processor which compacts
whitespace in the velocity code according to different rules. See
http://extensions.xwiki.org/xwiki/bin/view/Extension/Velocity+Macro+Filter for
more details.
> Template if statement throws off tabbing

> Key: VELOCITY-792
> URL: https://issues.apache.org/jira/browse/VELOCITY-792
> Project: Velocity
> Issue Type: Bug
> Environment: Eclipse IDE.
> Microsoft XP.
> Reporter: Kevin Swanson
>
> When using a velocity template for XML output. I encounter tabbing issues
> when using an IF statement. Below you can find an example of what is
> happening:
> Template which produces erroneous tabbing:
> #foreach($order in $orderList)
> <type>
> #if("$order.type" == "AZ")
> <AZ>
> <fiveYears>$order.typeVar1</fiveYears>
>
> <thirtyNineMonths>$order.typeVar2</thirtyNineMonths>
> </AZ>
> #end
> </type>
> #end
> Output of erroneous tabbing:
> <type>
> <AZ>
> <fiveYears>true</fiveYears>
> <thirtyNineMonths>false</thirtyNineMonths>
> </AZ>
> </type>
> If I remove the indentation from the #if and #end then the output is normal.
> Having to remove the indentation is undesirable as it makes the template
> difficult to read.
> Template with removed indentation for #if and #end:
> #foreach($order in $orderList)
> <type>
> #if("$order.type" == "AZ")
> <AZ>
> <fiveYears>$order.typeVar1</fiveYears>
>
> <thirtyNineMonths>$order.typeVar2</thirtyNineMonths>
> </AZ>
> #end
> </type>
> #end
> Output with indentation for #if and #end removed;
> <type>
> <AZ>
> <fiveYears>true</fiveYears>
> <thirtyNineMonths>false</thirtyNineMonths>
> </AZ>
> </type>
