I have the following code in a .erb file:
<% embed='<a href="http://someurl.com/whatever">#{@webcast.name}</a>'%>
<p id="embedCode">
<pre>
<code>
<%= embed %>
</code>
</pre>
</p>
The anchor tag is correctly displayed onscreen as text rather than rendered as a dom element, however the string interpolation is failing. The html is successfully displayed as text but #{@webcast.name} is not evaluated. If a include <%= @webcast.name => in the template, the webcast name in rendered successfully.

String Interpolation refers to substitution of defined variables or expressions in a given String with respected values. This is how, string Interpolation works, it executes whatever that is executable. Let's see how to execute numbers and strings. Syntax: #{variable}
Rubocop. Runs RuboCop on all ruby statements found in ERB templates. The RuboCop configuration that erb-lint uses can inherit from the configuration that the rest of your application uses.
ERB (or Ruby code generated by ERB ) returns a string in the same character encoding as the input string. When the input string has a magic comment, however, it returns a string in the encoding specified by the magic comment.
An ERB template looks like a plain-text document interspersed with tags containing Ruby code. When evaluated, this tagged code can modify text in the template. Puppet passes data to templates via special objects and variables, which you can use in the tagged Ruby code to control the templates' output.
Because strings delimited with single quotation marks '' are not interpolated.
Change your code to e.g.:
<% embed = "<a href=\"http://someurl.com/whatever\">#{@webcast.name}</a>" %>
or (if you want to avoid masking the double-quote characters ")
<% embed = %(<a href="http://someurl.com/whatever">#{@webcast.name}</a>) %>
or just (thanks to Samy Dindane for the hint):
<% embed = "<a href='http://someurl.com/whatever'>#{@webcast.name}</a>" %>
