Hi Felix
highway=* { name | '${ref} ${name} ${name1} ${name2}' | '${name} ${name1} ${name2}' | '${ref} ${name1} ${name2}' | '${ref} ${name} ${name2}' | '${ref} ${name} ${name}1' | '${ref} ${name} | '${ref} ${name1} | '${ref} ${name2} | '${name} ${name1} | '${name} ${name2} | '${name1} ${name2} | '${name}' | '${name1}' | '${name2}' | '${ref}'
}
In this case you could give each value a default value of nothing, so it would always match with just the one rule { name '${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}'; } But I see that didn't work because of a bug. That is now fixed and so the example will build up a string with spaces only where needed. The only problem would be that if ref doesn't exist, then there will be a space at the start. I can't see a way around this at the moment, but we could add something for that. ..Steve
