Well, it looks like this forum is doing this correctly. Any
ruby-forum.com dev's out there that can explain how they are both
escaping HTML and calling auto linking URLs?
I had the same problem. Here is a simplified version that worked for me:
def auto_link_urls (text)
url_regex = /
text.gsub(url_regex) do |link|
link = 'http://' + link if $1 == 'www.'
link_text = block_given? ? yield(link) : link
'<a href="' + link + '">' + link_text + '</a>'
It doesn't detect already linked URLs (I didn't need it) but it allows a
wider range of URLs (ftp://…, for example) and works with HTMLized
URLs (…?foo=1&bar=2…) and some other special case original
version doesn't seem to detect (http://www.example.com/?foo).
