If nobody is interested in using if-then-else in style I'd be happy to use only the style-option_v3.patch<br>

Betreff: [mkgmap-dev] if-then-else in style and style options<br>
<br>
Hi all,<br>
<br>
I've applied the style-option_v3.patch to the branch, for details see log message:<br>
<a href="http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3827" rel="noreferrer" target="_blank">http://www.mkgmap.org.uk/<wbr>websvn/revision.php?repname=<wbr>mkgmap&rev=3827</a><br>
<br>
I've also tried to fix the known problems with the interpretation of if then statements,<br>
so I hope it works now:<br>
<a href="http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&path=%2F&" rel="noreferrer" target="_blank">http://www.mkgmap.org.uk/<wbr>websvn/revision.php?repname=<wbr>mkgmap&path=%2F&</a><br>
<br>
Just to make this clear: The if statements are translated to "normal" rules, so you cannot do anything<br>
with if-then which would not work without, you should also not (yet) exprect run time improvements.<br>
The advantage is that you don't have to repeat phrases.<br>
<br>
A complex sample that shows a possible usage.<br>
# Roundabouts<br>
if (junction=roundabout) then<br>
if (mkgmap:option:single-<wbr>roundabout=true) then<br>
(highway=trunk | highway=trunk_link) [0x0c road_class=4 road_speed=2 resolution 18]<br>
(highway=primary | highway=primary_link) [0x0c road_class=3 road_speed=2 resolution 19]<br>
(highway=secondary | highway=secondary_link) [0x0c road_class=2 road_speed=2 resolution 20]<br>
(highway=tertiary | highway=tertiary_link) [0x0c road_class=1 road_speed=1 resolution 21]<br>
else<br>
(highway=trunk | highway=trunk_link) [0x0c road_class=4 road_speed=2 resolution 24 continue]<br>
(highway=trunk | highway=trunk_link) [0x10801 resolution 18]<br>
<br>
(highway=primary | highway=primary_link) [0x0c road_class=3 road_speed=2 resolution 24 continue]<br>
(highway=primary | highway=primary_link) [0x10802 resolution 19]<br>
<br>
(highway=secondary | highway=secondary_link) [0x0c road_class=2 road_speed=2 resolution 24 continue]<br>
(highway=secondary | highway=secondary_link) [0x10803 resolution 20]<br>
<br>
(highway=tertiary | highway=tertiary_link) [0x0c road_class=1 road_speed=1 resolution 24 continue]<br>
(highway=tertiary | highway=tertiary_link) [0x10804 resolution 21]<br>
end<br>
# minor roundabouts need no overlay<br>
(highway=unclassified | highway=minor ) [0x0c road_class=1 road_speed=1 resolution 21]<br>
highway=* [0x0c road_class=0 road_speed=1 resolution 22]<br>
end<br>
<br>
If the corresponding block in the default style lines file is replaced with these rules, you can<br>
use option --style-option=single-<wbr>roundabout to enable the rules which don't add 0x180x lines as overlays for roundabouts.<br>
<br>
It might be possible to completely remove rules which would never be triggered but that is quite complex, so I leave that for later.<br>
<br>
Gerd<br>
