get value of the string stored in a variable, whose name stored as string in another variable

Question

<#assign blah = "foo">
<#assign foo = "awesome">

Can we render "awesome" without referencing foo ?

I tried something like ${${blah}}

But it isn't working, any ideas ?

Answer 1

There is an eval built-in which evaluates a string as an FTL expression.

In your case use it like this:

${blah?eval}
