Crossplatform way to open a URL/browser

Question: do we have a nice way to open URLs, using our API?

I want to avoid any kind of OS/vendor-specific stuff (like, assuming that Internet Explorer, Safari is installed…)

The following code works, except for Linux:

--- open a URL in the default OS browser
function open_url_in_browser(str_url)
  if (os.platform() == "WINDOWS") then
    os.execute(("start %s"):format(str_url))
  elseif (os.platform() == "MACINTOSH") then
    os.execute(("open %s"):format(str_url))
  elseif (os.platform() == "LINUX") then
    renoise.app():show_message(("Please copy-paste the following link: \n%s"):format(str_url))
  end
end

Xdg-open?
X-www-browser?
Sensible-browser?

renoise.app():open_url("www.url.com")

Yes, that was it. Thanks!!
