[mkgmap-dev] amenity=restaurant and search index

Thu Apr 27 13:06:08 BST 2017

Hi all,
I think the categories in which you find something are probably sometimes wrong, and that might be caused by
wrong index data. For example, in MapSource I have a subcategory "international" in "Food & Drink" which shows no entries.
When I right click on a restaurant with type 0x2a13 it has two properties :
Food & Drink - "Ratskeller "
Marine - "Ratskeller"
When I left click the first entry and select "Feature Properties" I see Category Food&Drink, Subcategory International
I have no idea yet where this Marine entry comes from, looks completely wrong.

Hi

I had suspicions that the line:

amenity=restaurant & cuisine ~ '.*pizza.*' [0x2a0a resolution 24]

doesn't work, but never bother looking in detail. It would fall through
to:

amenity=restaurant & cuisine=* [0x2a13 resolution 24]

There is a slight reason to use a subtype when cuisine is specified and
not matched and no subtype (0x2a00) when no cuisine specified, in that
you can find these unknown cuisines by select-category:other

An improvement to the default style would be to change above to:

amenity=restaurant & cuisine=* {add name='${cuisine|subst:"_=> "}'}
[0x2a13 resolution 24]

and there are a few other places that would benefit from similar
changes
