[mkgmap-dev] process-exits vs process-destination

Wed Apr 10 19:32:10 BST 2013

Hi Franco,

process-exits and process-destination works fine together. In case the 
_link starts at an exit and contains a destination tag it is split and 
the middle part contains the tags:
mkgmap:exit_hint=true
mkgmap:dest_hint=true

You can have a look at the default style how to use that:
(highway=motorway_link | highway=trunk_link) & mkgmap:exit_hint=true & 
mkgmap:dest_hint=true
   { delete mkgmap:display_name;
     name '${destination:ref|subst: =>} ${destination|subst:;=> 
|subst:/=> }' |
          '${ref|subst: =>} ${destination|subst:;=> |subst:/=> }' |
          '${destination|subst:;=> |subst:/=> }' |
          'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_name}' |
          'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_exit_to}' |
          'Exit ${mkgmap:exit_hint_exit_to}' |
          'Exit ${mkgmap:exit_hint_name}' |
          'Exit ${mkgmap:exit_hint_ref}'
        }

(highway=motorway_link | highway=trunk_link) & mkgmap:exit_hint!=* & 
mkgmap:dest_hint=true
   { delete mkgmap:display_name;
     name '${destination:ref|subst: =>} ${destination|subst:;=> 
|subst:/=> }' |
          '${ref|subst: =>} ${destination|subst:;=> |subst:/=> }' |
          '${destination|subst:;=> |subst:/=> }'
        }

(highway=motorway_link | highway=trunk_link) & mkgmap:exit_hint=true & 
mkgmap:dest_hint!=*
   { delete mkgmap:display_name;
     name 'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_name}' |
          'Exit ${mkgmap:exit_hint_ref} ${mkgmap:exit_hint_exit_to}' |
          'Exit ${mkgmap:exit_hint_exit_to}' |
          'Exit ${mkgmap:exit_hint_name}' |
          'Exit ${mkgmap:exit_hint_ref}'
        }
