Markup Not Showing Up Using Prism JS

Question

I'm trying to use PrismJS as my syntax highlighter for my blogspot blog. After having troubles with Syntax Highlighter, I thought I would give prism a try.

My code look like this:

<pre class="line-numbers language-markup">
    <code>
        <b:if cond='data:blog.url == "http://domain.com/p/about.html"'>
            <style type="text/css">
                font-size: 22px;
            </style>
        </b:if>
    </code>
</pre>

I have included the prismjs file before the </head> tag.

The CSS works, there are no errors in my Chrome console, yet the script shows no markup.

I have a jsFiddle with the exact same code on my site, and it also doesn't show the line numbers, even though my site does. http://jsfiddle.net/fyqnz/

Any idea why this isn't working?

Answer 1

Did a little playing around with this plugin and found that replacing < and > with > and < was kind of a pain. For what its worth if you wrap your html with a script tag, everything highlights. Because html inside of an untyped script tag doesn't play nice with Visual Studio, I gave it a type of prism-html-markup.

<pre>
    <code class="language-markup">
        <script type="prism-html-markup">
            <h1 class="foo">h1. Heading 1</h1>
            <h2>h2. Heading 2</h2>
            <h3>h3. Heading 3</h3>
            <h4>h4. Heading 4</h4>
            <h5>h5. Heading 5</h5>
            <h6>h6. Heading 6</h6>
        </script>
    </code>
</pre>

Hope this helps!

Answer 2

The class="language-*" needs to go on the <code> element, not the <pre> element. I was making this mistake at first, too.

Updated with correct info

It appears the JS Fiddle doesn't like Prism. Working fine on CodePen and locally on my machine: http://codepen.io/anon/pen/xmwji. Prism uses Regex to identify the sections to highlight. Make sure you escape your code properly. Opening tags (the < symbol) should be written as <, and closing tags (the > symbol) as >.
