Hi all, the current data structures and algos in mkgmap are optimized to process existing tags. The latest requirements often asked for information that is not stored in tags. Of course it is possible to change mkgmap to support all kinds of queries similar to overpass api or SQL, but that would require a lot of changes in mkgmap and also a massive increase in resource consumption. I wouldn't want to go that way, esp. not when I see that Garmin seems to be willing to remove the support for the maps in the old format. I wonder if any of the existing tools allows to preprocess OSM data in a way that would allow to add tags using powerfull queries?

If it helps, I can see why it might be useful to find out which other OSM objects a node is part of, given that I'm just about to make use of exactly that capability in a lua script called from osm2pgsql. In my case it'd be "do something different for information route markers based on what route relation they're part of", but I can certainly see why someone might want to "do something different if they're mounted on a wall". This of course echoes Richard Fairhurst's post here back at http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2017q1/026289.html . Personally I'd find it extremely useful to be able to take say https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua and use that as a basis for styling both in OSM Carto and mkgmap, but unfortunately I've no idea what'd be needed on the Java/lua integration side.
