[mkgmap-dev] line rule not being triggered

Sat Feb 24 17:41:59 GMT 2018

Hi Ticker,

I can reproduce the error with other style functions as well.
This pattern seems not to work:
a=* & style_func()=val {...}
This works fine
a=* & style_func()!=val {...}
or
a=* & style_func()>val {...}

@Steve: I assume that the problem is in the rule optimizer?

Betreff: [mkgmap-dev] line rule not being triggered

Hi

I noticed that the default style was putting walkways around some piers
because of the line rule:

(man_made=pier | man_made=piste:halfpipe) & area!=yes
{add highway=footway; name '${ref} ${name}' | '${ref}' | '${name}' }

an example is:
WAY: 469580183 (50.73379039764404/-1.2820744514465332) [man_made=pier,
mkgmap:admin_level10=Whippingham, mkgmap:admin_level2=GBR,
mkgmap:admin_level4=England, mkgmap:admin_level5=South East,
mkgmap:admin_level6=Isle of Wight, name=Folly Pier]

which is using a closed way to draw the pier (and also has a defined
footpath along it)

Earlier on in my lines file I have:

# mark multipolygons as area
mkgmap:mp_created=true {add area=yes}

highway=* & area!=* & is_closed()=true {echotags 'closed() highway';
add area=yes}

and so added the following to fix the problem:

man_made=* & is_closed()=true {add area=yes; echotags 'mm'}

but this rule isn't being triggered by my example, but if I replace it
with:

name="Folly Pier" & is_closed()=true {add area=yes; echotags 'fp'}

Then it behaves as expected

I'm using the latest svn trunk (4127)

Any ideas?

Thanks
Ticker
