Ondra Žižka commented on FREEMARKER-73:
---------------------------------------
I see! I was trying it with numbers and got errors so I thought it's just an
empty string. Ok, makes sense. Thanks!
Yes, this is for Windup. Actually we have an Angular web UI too, but we also
generate offline analysis reports, for which Freemarker was chosen as the best
alternative. And the requirements for static documents stays for the next
versions.
> ?seq to convert some models to a sequence
> -----------------------------------------
>
> Key: FREEMARKER-73
> URL: https://issues.apache.org/jira/browse/FREEMARKER-73
> Project: Apache Freemarker
> Issue Type: Bug
> Components: engine
> Affects Versions: 2.3.26-incubating
> Reporter: Ondra Žižka
> Fix For: 2.3.27-incubating
>
>
> The objects I feed to FreeMarker often cotain {{Iterator}}s rather than
> {{Collection}}s.
> While it's quite easy to write a FreeMarker function
> {{iteratorToList(Iterator)}}, it would be convenient to have the following:
> A built-in that would convert various models to a sequence. Could be named
> {{?seq}} or {{?sequence}}.
> Usage:
> {code}<#assign foo = myIterable?seq>{code}
> {code}<#assign foo = myIterator?seq>{code}
> * A sequence would stay intact.
> * An {{Iterable}} wrapped in FM model would become internally a {{List}} -
> all elements consumed and stored.
> For me, other cases are not that important, but with some imagination, other
> models could also leverage it, like,
> * A {{Stream}} could be also turned into a {{List}}.
> * A hash could turn into a sequence of key/value pairs. That could be useful
> for debugging purposes.
> I am not sure if I didn't propose that already, but I could only find
> FREEMARKER-62.
> Thanks for considering.
