Hi Steve,
In this case you could give each value a default value of nothing, so it would always match with just the one rule
{ name '${ref|def:} ${name|def:} ${name1|def:} ${name2|def:}' }
But you would get extra spaces when any of the value were empty.
You should also be able to do this to append any number of things with only one line for each thing to be appended:
highway=* { set fullname=''; set fullname='${ref}'; set fullname='${fullname} ${name}'; set fullname='${fullname} ${name1}'; set fullname='${fullname} ${name2}'; name '${fullname}'; }
Thank you very much, I will try either approach for naming the bus stops. The attributes I'm planning to include are name, ref, operator, shelter=yes/no, possibly even amenity=waste_basket. Marko
