Nothing regarding the limits of 10m.<br>

I'm only saying that I keep mkgmap:exit_hint=true in my "lines" and it continues perform as expected.<br>

<p>Hi Alexandre,</p>
<p><br>
</p>
<p>Thanks for testing.<br>

<p>I see no problem with the code for process_exits, I think it only adds <br>
</p>
<p>tags with the mkgmap prefix. Do you mean the limits regarding 10m ? <br>

<div>Hi Gerd,<br>
<br>
</div>
After update my local mkgmap with this patch, follow my tests' results (in a small fictitious map):<br>
<br>
</div>
1) Without change my proprietary style "lines" file, I get the following error as expected:<br>
<div>
<div>
<div>
<div><br>
<span style="font-family:monospace,monospace">GRAVE (StyledConverter): 03137600-lagoa_santa.osm: At least one 'lines' rule in the style contains the expression mkgmap:dest_hint=true, it should be changed to mkgmap:dest_hint=*</span><br>
<br>
</div>
<div>2) Changing mkgmap:dest_hint=true to *, as directed above, the map was compiled without error and the result works as expected.<br>
<br>
</div>
<div>Therefore, I think that the patch is working like charm.<br>
<br>
</div>
<div>I didn't change any exit_hint in lines file and the exits continue working as expected. Are you changing only dest_hint or are you gonna change dest_exit also?<br>
<br>
</div>
<div>Regards,<br>
<br>

<p>Hi all,</p>
<p><br>
</p>
<p>please read carefully:</p>
<p><br>
</p>
<p>Up to now the process_destination option is a bit problematic because <br>
</p>
<p>it may add the tag destination=* to an existing OSM element, and I think this</p>
<p>is not good, all tags added by mkgmap should have the mkgmap: prefix.<br>
</p>
<p><br>
</p>
<p>As Greg pointed out this causes problems for style authors who want to</p>
<p>create special hints depending on tags like destination:street .<br>
</p>
<p><br>
</p>
<p>The attached patch changes the method like this:</p>
<p>1) the tag destination is not changed by mkgmap</p>
<p>2) Instead the special tag mkgmap:dest_hint is now set to the <br>
</p>
<p>destination string that was found in one of the tags listed in this code snippet:<br>
</p>
<p> 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>
</p>
<p><br>
</p>
<p>(BTW: This is also the order of evaluation in mkgmap searches since r3673, of cause
<br>
</p>
<p>forward/backward are checked depending on the direction of the way)<br>
</p>
<p><br>
</p>
<p>For style authors this means that they have to <br>
</p>
<p>1) change all rules with mkgmap:dest_hint=true to mkgmap:dest_hint=*</p>
<p>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>
</p>
<p>Basically all places where "destination" was used were changed to mkgmap:dest_hint.</p>
<p><br>
</p>
<p>I am aware that this could cause trouble, so I've added a check that complains when</p>
<p>the style contains an expression mkgmap:dest_hint=true . <br>
</p>
<p><br>
</p>
<p>A binary can be found here:</p>
<p><a href="http://files.mkgmap.org.uk/download/295/mkgmap.jar" target="_blank">http://files.mkgmap.org.uk/download/295/mkgmap.jar</a></p>
<p><br>
</p>
<p>With the default style this produces the same img file as r3673. <br>
</p>
<p>Please let me know if you see problems with your style.<span><font color="#888888"><br>
