How to handle ruby ​​url to retrieve components (scheme, username, password, host, etc.)?

Question

I am trying to create a program using ruby ​​(and Net :: SSH) to connect to servers and perform some tasks. Server details should be provided as something like:

ssh://user:pass@host:port (for a host that does not yet have SSH keys)

or

user@host

Net :: SSH expects the following format:

Net::SSH.start('host', 'user', :password => "password")

Is there any gem / stdlib that can handle the url in this format? Or a simple regular expression that can match different parts?

Note. I know and use capistrano, but in this case I need a lower level of control.
