dest_hint_v1.patch : change --process-destination option<br>
The process_destination option was a bit problematic because<br>
it could have added the tag destination=* to an existing OSM element.<br>
<br>
The attached patch changes the method like this:<br>
1) the tag destination is not changed by mkgmap<br>
2) Instead the special tag mkgmap:dest_hint is now set to the<br>
destination string that was found in one of the tags listed in this code snippet:<br>
tags.add("destination");<br>
tags.add("destination:lanes");<br>
tags.add("destination:lanes:forward");<br>
tags.add("destination:lanes:backward");<br>
tags.add("destination:forward");<br>
tags.add("destination:backward");<br>
tags.add("destination:street");<br>
<br>
<br>
(BTW: This is also the order of evaluation in mkgmap searches since r3673, of cause<br>
forward/backward are checked depending on the direction of the way)<br>
<br>
For style authors this means that they have to<br>
1) change all rules with mkgmap:dest_hint=true to mkgmap:dest_hint=*<br>
2) change the rule that produces the hint to something like this:<br>
mkgmap:dest_hint=*<br>
{ set dest_hint = '${destination:ref|subst: =>} ${mkgmap:dest_hint|subst:;=> |subst:/=> }' |<br>
'${ref|subst: =>} ${mkgmap:dest_hint|subst:;=> |subst:/=> }' |<br>
'${mkgmap:dest_hint|subst:;=> |subst:/=> }';<br>
}<br>
<br>
Basically all places where "destination" was used were changed to mkgmap:dest_hint.<br>
This could cause trouble, so I've added a check that complains when<br>
the style contains an expression mkgmap:dest_hint=true.<br>
