SM::ToHtml does not convert urls to hyperlinks

I am trying to use my own output formatter with SimpleMarkup. Things seems =
to work, except for hyperlinks not working as expected. I tried to use SM::=
ToHtml to simplify things, and even if does not deal with hyperlinks. Here =
is the code snippet I am using.

require 'rdoc/markup/simple_markup'
require 'rdoc/markup/simple_markup/to_html'
s =3D "This is *bold*. These are urls - www.foo.com<http://www.f... , h=
ttp://www.foo.com , foo[http://w...]"
p =3D SM::SimpleMarkup.new
puts p.convert(s, SM::ToHtml.new)

The output of this is as shown below. The word "bold" was surrounded by the=
<b> tag, but the urls were not surrounded with <a href> tags.

<p>
This is <b>bold</b>. These are urls - www.foo.com<http://www.f... , htt=
p://www.foo.com , foo[http://w...]
</p>

Is there a way to make this happen?

Regards,
Shri

You should use RDoc::Markup from RDoc 2. RDoc 1's SM is no longer
maintained.

As described in ri RDoc (for RDoc 2), valid URL formats are:

So, adjusting your input to fit:

$ echo 'This is *bold*. These are urls - http://w..., foo[http://w...
]' | rdoc --pipe
<p>
This is <b>bold</b>. These are urls - <a
href="http://w...">www.foo.com</a>, <a
href="http://w...">foo</a>
