Instead of embedding a <a href="http://gist.github.com" rel="nofollow ugc">GitHub Gist</a> (a <a href="http://pastie.org/" rel="nofollow ugc">pastie</a> like service on steroids) by copying and pasting HTML you can simple embed it with a [gist] shortcode.
For example, to embed the <a href="http://gist.github.com/30948" rel="nofollow ugc">gist: 30948</a> enter this in a post or page:
<pre><code>[gist id=30948]
</code></pre>
It is that simple.
One problem with gists is that a search engine spiders (and users with javascript disabled) will not see your code in a blog entry. This plugin allows you to get around this by including text, such as content of the gist inside the shortcode. The text is wrapped inside these tags:
<pre><code><noscript><code class="gist"><pre>
</code></pre>
You would use it like this:
<pre><code>[gist id=30948]
puts hello_world_test;
i = 0
5.times do
 i = i + 1
 puts i
end
[/gist]
</code></pre>
The content inside a gist shortcode is optional.

With FF Block Gist Embed you can embed files from GitHub Gists. It adds a block named ‘Gist Embed’ to the WordPress editor interface. For every instance of this block, you can:
<ul>
<li>Select one or more files from the same Gist URL to be embedded in your post.</li>
<li>Include the vendor stylesheet that handles the styling of Gist embeds (see the FAQ for more information).</li>
<li>Choose whether or not to embed the Gist files as raw content.</li>
</ul>
<h3>Roadmap</h3>
We would like to bring some additional features soon. Some of the things we have planned, are:
<ul>
<li>Caching the content of files</li>
<li>Manually change the order of the files from a Gist within a block</li>
<li>Automatically get the list of files after a valid Gist URL is entered in the input field</li>
</ul>

FF Block Gist Embed

This block works great for adding Gists to your posts and pages.

However, it desperately need a preview option so that you can see the results in the editor.

But, otherwise, a fantastic addition for any developer wanting to share their code.

A simple but effective Gist block
