Just found this little thingy which according to me is quite impressive.

<cfset obj = createObject("java","coldfusion.util.FormatSource")>
<cfoutput>
#obj.formatFile(Expandpath('cfdirectory.cfm'))#
</cfoutput>

Now what that does is takes a file from your local folder and applies colored coding to it. Not the best colored code but a lot better than the heavy Regular expression.

Try it out !
