.pseudo_uri(opts = {}) ⇒ String?

Construct a probably-correct (or correct-enough) URI for tools like ssh or rsync. Currently lacking support for intuitive joins, ports, protocols, fragments, or 75% of what Addressable::URI or URI would provide out of the box. The “win” here is that the returned String should “just work”.

Parameters:

  • opts (Hash) (defaults to: {}) —

    fragments used to build the pseudo URI

Options Hash (opts):

  • :path (String) —

    URI-ish path component

  • :host (String) —

    URI-ish host component

Returns:

  • (String, nil) —

    a string representing either a hostname:/path pair, a hostname without a path, or a path without a hostname. Returns nil if it is unable to construct a useful URI-like string.
