OK, I think I see how the concatenation is done now.
I changed my lines file to thus (relation tag route_display_name is set in relations):
type=route & route_display_name=* { apply { set route_display_name='$(route_display_name),${route_display_name}'; } } (highway=track | highway=bridleway | highway=cycleway | highway=footway) & route_display_name=* {set name='${route_display_name}' continue with_actions}
But I do not get a comma separated list of names, still just a single name showing in Mapsource or Basecamp - and without a comma.
Also why does this does this not replace names already defined for a track/bridleway etc!!!!???? It only gets set if the name is not already set.
Did you have a look at the the default style? It sets bus route $ref in highway=bus_stop relations. It also sets the boundary names on boundary lines (not sure if that is still being used). But, let me quote it: (type=boundary | type=multipolygon) & boundary=administrative & name=* { apply { set mkgmap:boundary_name='$(mkgmap:boundary_name)/${name}' | '${name}'; } } The ${name} refers to the relation attribute. The 'set' and $(mkgmap:boundary_name) [note $(...) instead of ${...}] refers to the relation member. This command will do one of two things: (1) if 'mkgmap:boundary_name' is not already set on the member, assigns it to the 'name' of the relation (2) otherwise, appends '/' and the relation name to mkgmap:boundary_name This parameter is used in the default/lines file to assign a name for the boundary: boundary=administrative { name '${mkgmap:boundary_name}' } Technically, I guess you could write something like this directly: apply { set name='$(name)/${name}' | '${name}' } However, this could be a bad idea, because it would overwrite the name of any relation member, such as a section of a river or a highway (if they are part of the relation). Also, have a look at the styles/default/routes-* relations. I used to build a multi-layer map that had --style=routes-bus and --style=routes-bicycle in separate transparent layers, selectable on the maps menu in the device. Best regards, Marko
