[jira] [Commented] (FREEMARKER-37) ability to skip iteration in a list

["Daniel Dekany (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FREEMARKER-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15626370#comment-15626370 ] 

Daniel Dekany commented on FREEMARKER-37:
-----------------------------------------

The problem is deeper than that, because {{#list}} isn't just an odd name for {{for}}. {{#list}} deals with things like item separators, item index, etc. Thus if you skip items like that (with a big {{#if}} or a {{#continue}]), you can't use those features. So the real solution would be list filtering... which is a more difficult problem than {{#continue}}. So, yeah, skipping is badly needed, but {{#continue}} is not the good solution for it.

> Sorely missing ability to skip through an iteration of a list and continue on with the rest of the list. would like to write clean code like this:
> <#list collection as element>
>         <#if element.attr1 == "some_value"> 
>                 <#continue />  <#-- skip over this item and run next item in loop -->
>         </#if>
>     do stuff here
> </#list>
> Thanks!
