[FreeMarker-user] Forwarding freemarker vararg parameter

[Albert Kam]

Hi all,

I have a function that accepts a vararg param, which i want to pass to
another function that also has the vararg param :

<#function process extras...>
<#local result=anotherProcess(extras)>
...
</#function>

<#function anotherProcess extras...>
...
</#function>

And if i call process(1, 2, 3), then on process(), the extras is [1, 2, 3].
But when extras is passed to anotherProcess(), the extras is now [[1, 2,
3]], where i expect it to be [1, 2, 3].

Is there a way to pass the extras as 'expanded' list to anotherProcess, or
in other words, just forward the 'extras' vararg as is ?

Thank you !

Unfortunately there's no feature for that. As a work around, you can
introduce a non-varargs variant of the "anotherProcess" function, that
expects a list but without using "..." in the declaration, and then
call that from both the "process" and "anotherProcess" functions.
