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 = “This is _bold_. These are urls - [www.foo.com](http://www.foo.com)[http://www.foo.com](http://www.foo.com) ,  
[http://www.foo.com](http://www.foo.com) , foo[[http://www.foo.com](http://www.foo.com)]”  
p = 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 **tag, but the urls were not surrounded with tags.**

 

**This is bold. These are urls - www.foo.com , http://www.foo.com , foo[http://www.foo.com]**

 

**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 RDoc 1’s SM is no longer  
maintained.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://www.foo.com](http://www.foo.com),  
foo[[http://www.foo.com](http://www.foo.com)  
]’ | rdoc --pipe

This is **bold**. These are urls - [www.foo.com](http://www.foo.com), [foo](http://www.foo.com)
