Jekyll 3.0.0-beta1/Liquid 3 Issue with Handlebars highlighting

[KevinGimbel]

After upgrading to Jekyll 3.0.0-beta1 I get the following Liquid Error for one of my posts:

jekyll 3.0.0-beta1 | Error:  Liquid syntax error: Unexpected character # in "{{#post}}"

The specific part of the post is the following:

{% highlight html %}
{% raw %}
{{#post }}
  <article class="post">
    <hgroup>
      <h2>{{{title}}}</h2>
      {{#if author}}
        written by {{author.name}}
      {{/if}}
    </hgroup>
  </article>
{{/post}}
{% endraw %}
{% endhighlight %}

I used the {% raw %} tags here to prevent Jekyll/Liquid from parsing the Handelbars code snippet. Now with the latest version of either Liquid or Jekyll this seems to not work anymore and I can't build my site.

I couldn't find a open issue or a temporary workaround for this. Any ideas how to prevent this?

Additional info:

Can you please try with beta2 and confirm it's still broken there so we can block the next beta?

[KevinGimbel]

When I use the beta2 release I get the following Errors:

  Build Warning: Layout 'nil' requested in article.json does not exist.
  Build Warning: Layout 'nil' requested in atom.xml does not exist.
  Liquid Exception: Liquid syntax error: Expected end_of_string but found pipe in "post in site.posts | limit: 10" in _layouts/front-page.html

So with this release it seems that limits are broken. The Error with Raw Tags and Handlebars Syntax are still present unfortunately.

Affected file: https://github.com/kevingimbel/kevingimbel.github.io/blob/master/_layouts/front-page.html#L8
Jekyll Version: 3.0.0.beta2

Can you please file a unique bug for that one and attach it to this ticket by ref-ing it.

Is this fixed?

[envygeeks]

Not that I know of, it still existed in beta2? If he doesn't respond I'll test and see tonight.

Plot twist. This works:

require 'liquid'
require "#{ENV['HOME']}/jekyll/jekyll/lib/jekyll.rb"

class SomeSite
  def safe
    true
  end

  def highlighter
    'pygments'
  end
end

content = <<-EOS
{% highlight html %}
{% raw %}
{{#post}}
  <article class="post">
    <hgroup>
      <h2>{{{title}}}</h2>
      {{#if author}}
        written by {{author.name}}
      {{/if}}
    </hgroup>
  </article>
{{/post}}
{% endraw %}
{% endhighlight %}
EOS

puts Liquid::Template.parse(content).render({}, { :registers => { :site => SomeSite.new } })

@parkr,

Does that fix the build warning? At least for the feed template I'm using (one of TPW's originals, IIRC), you need to pass null to get around any errors. This has come up a few times if memory serves - #2712 and #2730 - as well as some I've probably forgotten about.

[parkr]

@chrisfinazzo Indeed, thanks! Your layout should be null instead of nil if you want no layout.

Looks like we fixed your other issue before in #3559.
