How about this:
tag 'date' do |tag|
page = tag.locals.page
format = (tag.attr['format'] || '%A, %B %d, %Y')
which = tag.attr['which']
if which
if (which == 'now')
date = Date::Time.now
elsif ['published_at', 'created_at', 'updated_at'].include? which
date = page[which]
else
raise TagError, "Invalid value for 'which' attribute."
end
else
date = page.published_at || page.created_at
end
date.strftime(format)
end
Notice that I made sure it's a valid attribute, otherwise raising an error.
If none of the core team has problems with this, I'll write some tests
and patch it into mental.
