I made a hacky script to generate .yml from XAPI output (attached):
perl -CI place2yaml.pl < place.osm > place.yml
But I just get internal server errors from the CM API:
$ ruby routes.rb place.yml
[Tue Dec 01 18:59:57 +0000 2009] HTTP error: Couldn't read data. HTTP
status: #<Net::HTTPInternalServerError:0xb769348c>, retrying...
Anyway do you have a script to generate that cute HTML matrix? And how
can I link to a route on CM's website. I have to supply lat/lon/zoom
it seems and not just starting/ending lat/lon (at least the URLs I've
seen are all like that).
