I am coming to a point when maintaining my lines file, that adding a single key on top, means 200-300 lines more. This is becoming unmaintainable. It would be great to have the option to have rules just like the ones we have for POI that one can run on certain keys. e.g. lanes=2 & oneway=yes { add mkgmap:road-speed = '-1'; add mkgmap:road-class = '-1'; } This should then be matched to all lines that are generated after this command. As this is already possible for POI, I hope someone could without much effort implement this for rules based on tags too. This would be very useful as it saves many many lines of code. Currently if you would like to do something like this, it means that you have to add the rule to every line (with autorouting) in your lines file. This is okay for one or to tags (like some people do for maxspeed), but it becomes impossible to keep track once you have 10 tags you like to be enacted. If there are several rules matching, they should simply add up. (or equalise themselves if +1 meets -1...) It would be really great if someone could implement this feature. As it exists already for POI when using link-pois-to-ways I have the great hope that it is easy to implement and program and someone finds some spare time to do it. This could really help to avoid creating a ton of rules and open up many new possibilities to much better finetune road_class and road_speed. It would be a plus, if one could only "apply" this rule until a stop rule is given. Quick example lanes=2 & oneway=yes { add mkgmap:road-speed = '+1'; add mkgmap:road-class = '+1'; set rule=1 } highway=primary & maxspeed=100 {road_class=3 road_speed=4 0x02] highway=primary .... highway=secondary... .... rule=1 {stop execution}
