Hi all,
I'd lile to merge the branch soon and do some more refactoring to simplify the
code.
I think the branch is fully backward compatible with trunk, that means,
it should work with existing maps and should produce equal maps.
It brings three changes:
1) It adds if-then-else syntax for styles, might be useful for doing this:
if (mkgmap:option:routing=car) then
include "inc/car-rules";
end
2) It adds the new option --style-option :
--style-option
Provide a semicolon separated list of tags which can be used in the
style.
The intended use is to make a single style more flexible, e.g.
you may want to use a slightly different set of rules for a map of
a whole continent. The tags given will be prefixed with
"mkgmap:option:".
If no value is provided the default "true" is used.
This option allows to use rules like
mkgmap:option:light=true & landuse=farmland {remove landuse}
Example: -- style-option=light;routing=car
will add the tags mkgmap:option:light=true and mkgmap:option:routing=car
to each element before style processing happens.
3) It adds the possibility to add multiple map objects with a singe rule, e.g.
two rules using the same expression like
junction=roundabout & (highway=trunk | highway=trunk_link) [0x0c road_class=4
road_speed=2 resolution 24 continue]
junction=roundabout & (highway=trunk | highway=trunk_link) [0x10801 resolution
18]
can be written like this:
junction=roundabout & (highway=trunk | highway=trunk_link) [0x0c road_class=4
road_speed=2 resolution 24] [0x10801 resolution 18]
If I hear no complains I'll do the merge on tuesday.
Gerd
