[mkgmap-dev] Commit: r2658: Use mkgmap:street tag to get street name for house number search

Fri Jul 19 16:46:44 BST 2013

Actually neither of the two lines works!!!!

Have I understood wrong how it should work?
name=* {set mkgmap:street='${name}'} as first line in my lines file, 
doesn't help. I still get all the added "junk" like refs or route names 
and so on in the address search (used mapsource to try it out)...
highway=* & name=* {set mkgmap:street='${name}'} also has no effect at 
all on the address search.

where is my error?
