I had the same problem, I ended up implementing two custom tags:
Behavior::Base.define_child_tags do
tag 'if_current_page' do |tag|
if tag.locals.page == tag.globals.page
tag.expand
end
end
tag 'if_current_parent' do |tag|
potential_parent = tag.locals.page
child = tag.globals.page
if child.child_of? potential_parent
tag.expand
end
end
end
I also patched Page to add Page#child_of? (used in
<r:if_current_parent>) but you could do it inline.
Then in my navigation snippet I used these to conditionally show the
children/siblings of the page in question...
For some reason I needed to use #define_child_tags rather than
#define_tags, as the custom tags wouldn't be available in pages with a
custom behaviour. John, if you read this, would you be able to take a
second and explain why? (I couldn't quite figure it out going through
the code)
