Hi Gerd, I may be misunderstanding this, but the explanation of when it is enabled seems illogical.
It seems to me that reversing should be the default except on ways that have mkgmap:has-direction=true unless a switch is given to disable it. Or it could be off by default and a switch enables it, except for ways that have mkgmap:has-direction=true.

The routing tags oneway=yes or oneway=-1 have the same effect, but they also effect routing. Use this tag if you have a TYP file which renders lines different (e.g. cycleway on the right or on the left side) to prevent a reverse merge - implements new experimental option --x-force-reverse-merge Merging with reverse produces smaller maps, esp. smaller NET and NOD files, it may have an influence on routing. Reversing of roads is disabled unless mkgmap detects that the style has at least one rule which adds mkgmap:has-direction=true in rule file lines or option --x-force-reverse-merge is used. The program checks if any line that was added for a given OSM way has the tag mkgmap:has-direction=true. If one is found the tag is propagated to the road(s) for that OSM way so no reversing happens. Roads with different direction attributes are not merged. The option --x-force-reverse-merge is meant for those who don't use a TYP file or don't render left/right attributes with different types. All others should not use the option and adapt the style instead. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4703 _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
