Yeah, this is one place where SLD is actually less verbose (because it
magically wraps sequences of expressions in a function call that
concatenates them as strings.)
This syntax should work (untested though):
label: [strConcat(strConcat(strConcat(strConcat("[", attr1), "] (["),
attr2), "])")];
Pretty gross, right? If I think about it a bit I could probably make it
possible to avoid the strConcats; the rule would be that if a list of
properties is found for a label, it is implicitly concatenated. I don't
want to make whitespace significant outside of string literals though, so it
would come out something like this:
label: "[" [attr1] "] ([" [attr2] "])";
(remember if there are commas that means multiple labels.)
What do you think?
