With soy, I would like to concatenate two strings (hard-coded or variables) into one. My idea was to "parametrize" the first variable with the second:
{let $key: 'abc_$anothervariable' /}
This doesn't work. I also tried using builtin join() function for lists:
{let $key: join(['abc', $anothervariable], '') /}
But this approach doesn't work either - it even seems to have invalid syntax. Is it even possible to do something like that in Closure Templates?
The answer actually turned out to be as easy as:
{let $key: 'abc_' + $anothervariable /}
