I implemented the $(variable_name) syntax some time ago, to get bus
route relations translated properly. An excerpt from --style=routes:
[relations file]
type=route & ... {
apply { set mkgmap:route='$(mkgmap:route),${ref}' | '${ref}' }
}
[lines file]
highway=* & mkgmap:route=* { name '${mkgmap:route}' } [0x1d resolution 16]
Note that in the apply rule, the $(mkgmap:route) is referring to an
attribute of the relation member, and the ${ref} is referring to an
attribute of the relation.
What I would like to see is "apply" sorted by some criterion, and the
possibility to filter out duplicates, for example, when the same way is
part of opposite-direction bus route relations. (Opposing bus routes of
the same line can consist of oneway segments as well as shared
non-oneway segments. Now I will see "742,742" on the non-oneways and
just "742" on the oneways.)
I'd also like to have mkgmap generate multiple map layers in one go, so
that for type=route relations, different values of route=* would go to
different layers. You normally might want to see only one of route=road,
route=bicycle, route=bus at a time (by selecting visible map layers on
the device).
Do we have a bug tracking system or a wiki page for tracking this kind
of long-term, hard-to-implement feature requests?
