Hi all, I see no need to use if-then for this. Attached is a quick patch to add an option like --style-option=<val> to mkgmap. If specified, it tells mkgmp to add the tag mkgmap:style-option=<val> to each element before style processing. Sample usage with the attached patch: java -jar mkgmap.jar --x-style-option="car,show_farms" ... test.osm Style rule: landuse=farmland & mgkmap:style-option ~ '.*show_farms.*' [0x10f01 level 1] or if applied in the if-then branch: if (mgkmap:style-option ~ '.*show_farms.*') then landuse=farmland [0x10f01 level 1] end If you think that would be useful I'll add help and docu for it so that one can use it without the -x prefix.

I develop a single style for my topo maps, but I need some possibility to get a small variation in style depending on region. For example I prefer to show landuse=farmland on a map of Africa but to remove it on a map of Europe. So instead of maintaining 2 nearly identical styles, I would like to get a conditional statement, something like:
if (SHOW_FARMS) ( landuse=farmland [0x10f01 level 1] )
and then add (or not) an option to mkgmap like --style-define=SHOW_FARMS
