Agreed. I can now do the following to have a heading that is itself a
link to the parent page, in the manner of many Wiki engines:
<h1>
<r:parent><r:link><r:page><r:title /></r:page></r:link></r:parent>
</h1>
However, this breaks horribly on the root page and in so doing reveals a
small bug in the parent tag code. It needs this tweak:
define_tag 'parent' do |tag|
tag.locals.page = page.parent || page
tag.expand
end
Note the "|| page" on the second line.
Things get a bit hideous if we want to avoid having a link on the Home
page in the heading, though, assuming you're using the construct above
in a layout. Indenting things a bit to make it more legible, I've got
this right now:
<r:unless_url matches="^/$">
<r:parent><r:link>
<r:page><r:title /></r:page>
</r:link></r:parent>
</r:unless_url>
<r:if_url matches="^/$">
<r:title />
</r:if_url>
Is there a more elegant approach?
