Can you implement these rules? It should be in relation-file:
type=destination_sign { apply role=to { set foobar:destination=='$(foobar:destination),${destination}' | '${destination}' } }
Now every to-way is tagged with destination-Tags of all relations seperated by ,
In lines-file you would need something like:
highway!=*_link { delete foobar:destination }
Maybe you would like to merge foobar:destination with an existing desination, but I don't know if this is a good idea.
Ok, it seems to be possible. (Really? is ${foobar:destination} taken from the element or from the relation?). At the end of relation-processing foobar:destination contains a list of all relation-destination-tags.
* The --process-destination option does not know the foobar:destination tag. So it will still ignore the tags if they are not merged with the destination tag within the relations file. Mmh, don't know a good solution for that. My thought was, that if there are relations, then normal destination-tag can be ignored.
* The stlye implementation seems to be quite complex to me. It may be more useful if it's possible to add some rules in the relations file regarding the elements, so something like
type=destination_sign { apply role=to & member:type=way & member:tag:destination!=* { set destination=='$(member:tag:destination),${destination}' | '${destination}' } }
Could be good testcase to extend the relations file capabilities. To make it save, you'll need something like this. member:type=way shouldn't be necessary, because it doesn't harm, if its copied to a node, does it? Maybe the new filter-function can also help.
