In Jekyll, is there a concise way to render a Markdown partial?

I've got a Markdown-formatted sidebar that I'd like to show up in my Jekyll blog. I'd previously tried to include it like {% include sidebar.markdown %} but it wouldn't actually render the Markdown. I can successfully include it like:

{% capture sidebar %}{% include sidebar.markdown %}{% endcapture %}
{{ sidebar | markdownify }}

and although this is a manageable solution, I'd prefer a more开发者_开发百科 elegant way of accomplishing this. Any ideas? Thanks in advance!

I was looking for this too, it was a PITA discovering how to do it, not much Google content, the most exact finding was a gist that wouldn't work here... dead simple solution:

./_plugins/markdown_tag.rb:

module Jekyll
  class MarkdownTag < Liquid::Tag
    def initialize(tag_name, text, tokens)
      super
      @text = text.strip
    end
    require "kramdown"
    def render(context)
      tmpl = File.read File.join Dir.pwd, "_includes", @text
      Jekyll::Converters::Markdown::KramdownParser.new(Jekyll.configuration()).convert(tmpl)
    end
  end
end
Liquid::Template.register_tag('markdown', Jekyll::MarkdownTag)

Jekyll now supports writing simple plugins to add tags, converters, or generators. Take a look at http://jekyllrb.com/docs/plugins/ for details.
