See src/uk/me/parabola/mkgmap/osmstyle/actions/ActionReader.java, the role=value parsing is in readAllCmd. In ActionReader there is also an apply_once command included. Can this be used to prevent the forward/backward-doubling? Or what is the intended use of apply_once vs. apply?

There's this: http://wiki.openstreetmap.org/wiki/Mkgmap#Known_issues Charlie, thank you for the hint. Now there is http://wiki.openstreetmap.org/wiki/Mkgmap#Relations discussing the limitations related to relations that I have thought of. It also links to the page http://wiki.openstreetmap.org/wiki/Mkgmap/help/style_rules#apply where the substitution $(variable_name) has been documented. Now that I wrote http://wiki.openstreetmap.org/wiki/Mkgmap/help/style_rules#apply_once, all of this thread should be summarized on the mkgmap wiki pages.

[mkgmap-dev] tag values of relations and tag values of its members
Hallo,
is there any way to use the tag values of the members of a relation within the
apply command in the relations style file?
With
apply {set Member_Tag_Value=${Relation_Tag_Value}}
I can set the tag value of the relation to all its members.
Instead of just setting the tag in the member, I would like to combine it with a
tag value from the member. Something like
apply {set Member_Tag_Value='${Member_Tag_Value} and ${Relation_Tag_Value}'}
Can this be done somehow?
And as a related question: I it possible to include tags of the member of the
relation in the tag test of a relation rule?

Re: [mkgmap-dev] tag values of relations and tag values of its members
long time ago I have done it with a temporary tag name in the relations file.
and then in the line style test for existence of the temporary tag and combine
with the tag values from the lines
the only change you need is to test the existence of Relation_Tag_Value in the
line style

What I want to achieve is, that multiple relations can add information to a single way. E.g. A way A is member of relation relation B and also member of relation C, beside their name both relations are tagged in the same way. And in the map I want to have a name for the way like A is member of B and member of C. With a temporary tag I think I will eitehr get the result A is member of B or A is member of C But I do not see any way rigth now, how both relations can add their information to way A at the same time.

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?

Thank you very much, that was the information I was mainly looking for.
I will add this information also on the style rules page in the Wiki.

just 742 on the oneways.)
Is there any way to check for the role of the member inside the style rules?
