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.

GitHub Gist Shortcode Plugin

Allows the use of a simple shortcode to embed GitHub Gists in a post or page.

James Robinson

A simple plugin that enables a shortcode for embedding Gist code in WordPress.
The shortcode has two attributes, the Gist source URL and, optionally, the height of the embedded code window.
<pre><code>[gist src="" height=""]
</code></pre>
The Gist <code>src</code> attribute must be the embed URL, for example: https://gist.github.com/imaginarymedia/316a29936e5e7d709665.js
The Gist <code>height</code> attribute is optional and can be any value with a valid CSS unit measure: em, %, px, vh, etc. It will apply a max-height to the gist.
The plugin also creates UI buttons for both the visual and text editors.
