pf » Auto-Linking Comments

To avoid comment spam, my blog comments are displayed as plain text. However urls to other entries on my blog are often posted to in the comments. So I wrote a simple regular expression to create hyperlinks out of them:

REReplaceNoCase(comments.comment, 
	"(http://www\.petefreitag\.com/[^[:space:]]+)",
	"<a href=""\1"">\1</a>", 
	"ALL")

If you want this to work with or without the www you can use something like this for the regular expression:

(http://w*\.?petefreitag\.com/[^[:space:]]+)
