[josm-dev] composing display name for relations from operator ref name from via to

[Jiri Klement]

Hi,

Extending name template to work with parent relations or members or
any other related primitives shouldn't be too difficult, general idea
is to add new construct that will have search expression to select
from which primitive should be tags taken and inner name template.

Query that gets name tag of parent relation with type=route can look like this:
!{parent this type=route '{name}'}

parent this type=route - normal search expression, only difference is
new keyword - this - that return primitive for which the name is
constructed
'{name}' - use value of name tag.

Of course, inner template is generic, it would be possible to do
something like this: (show ref of parent relation if available)
!{parent this type=route '{name}?{ ' ({ref}) ' | '' }'}
