Hi,

I'm no Ruby expert, but I've been playing around with osmexport for awhile
and trying to export various osm data to shapefiles.  The biggest problem I
face is when I want to export the names of objects in a language different
from that with the tag "name", because no matter what I do the colon in
"name:en" doesn't work in Ruby.

ways do
    if highway
        :road << {:Type => highway, :Name => name:en, :Surface => surface}
    end
end

Of course this doesn't work.  It looks like I should do something like:

ways do
   if tags['name:en']
      ...
   end
end

But I still don't understand how to get the value of the "name:en" tag into
the Name field.  Help?

Jeff

I might be misunderstanding you, and I do not have much experience with 
osmlib myself, but have you tried something like:

ways do
    if tags['name:en']
        tags['name'] = tags['name:en']
    end
end

The methods like "highway", ... do not exist, but are actually syntactic 
sugar and are mapped in the OSMObject#method_missing method to the 
tags['highway'], ... hash access. So in case a key is not a valid ruby 
identifier, you can use that syntax directly. This also works for 
assignments to the key.

Yours,
