Sie könnten immer ein neues Liquid-Tag hinzufügen. Hier ist eine Skizze basierend auf post_url.rb:
class PostTitle < Liquid::Tag
def initialize(tag_name, post, tokens)
super
@orig_post = post.strip
begin
@post = Jekyll::Tags::PostComparer.new(@orig_post)
rescue => e
raise Jekyll::Errors::PostURLError, <<-eos
Could not parse name of post "#{@orig_post}" in tag 'post_title'.
Make sure the post exists and the name is correct.
#{e.class}: #{e.message}
eos
end
end
def render(context)
site = context.registers[:site]
site.posts.docs.each do |p|
return p.data.title if @post == p
end
raise Jekyll::Errors::PostURLError, <<-eos
Could not find post "#{@orig_post}" in tag 'post_title'.
Make sure the post exists and the name is correct.
eos
end
end
Liquid::Template.register_tag('post_title', PostTitle)
