here's a pure-TT implementation that might be an interesting start:
[%-
BLOCK mm;
DEFAULT separator = " ";
DEFAULT list_prefix = "";
DEFAULT list_suffix = "";
mylist = list.list;
IF mylist.size == 0;
ELSIF mylist.size == 1;
mylist.0;
ELSE;
FOREACH item = mylist;
list_prefix IF loop.first;
INCLUDE mm list = item;
IF loop.last; list_suffix; ELSE; separator; END;
END;
END;
END;
-%]
And now for the tests:
[% INCLUDE mm
list = ["hello", ["world", "we", ["do", "see"], "really"], "smartly"]
%]
[% INCLUDE mm
list = ["hello", ["world", "we", ["do", "see"], "really"], "smartly"]
separator = ","
%]
[% INCLUDE mm
list = ["hello", ["world", "we", ["do", "see"], "really"], "smartly"]
separator = ","
list_prefix = "("
list_suffix = ")"
%]
