Shortcode design?

What would you recommend for a shortcode find/replace design similar
to wordpress on select fields?: http://codex.wordpress.org/Shortcode_API

(Or does something like this already exist, and I'm just not using the
right search terms?)

This looks to me like a feature designed for CMS system. Rails is not a
CMS. It is a general purpose web framework. There are a number of CMS
systems developed using Rails. Maybe this question would be more
appropriate on forum dedicated to one of those.
