A few months back I switched from Textmate to Vim. Overall I really love Vim, but one of the things I miss from Textmate is using the ⌘R command to run Ruby code and having the results neatly pop up in a new, scrollable window. Obviously, Vim is capable of running Ruby code and displaying the output with :w !ruby. The only downside to this is that if the resulting output is too long I can't scroll through it.

To combat this problem I tried modifying a :redir function from Vim Tips. It looks like this:

function! TabNew(cmd)
  redir => message
  silent execute a:cmd
  redir END
  tabnew
  silent put=message
  set nomodified
endfunction
command! -nargs=+ -complete=command TabNew call TabNew(<q-args>)

Now the output from Ruby is put into a new tab. However, I can't get it to pop up in a new, separate window. Changing tabnew to new just sends the output to a split in the same window.

The other problem is that a visible ^M gets appended to the end of each line, so the output ends up looking like this, which is kind of bothersome:

Hello World!^M

So, is there any way to get the output into a separate window without the ^M appended to the end? Are there any plugins I should be trying to achieve this Textmate-like effect for code output?
