Hello. Here is an example:

Addressable::URI.parse("https://user:[email protected]").omit(:scheme, :port, :user, :password, :host)
Traceback (most recent call last):
        1: from (irb):22
Addressable::URI::InvalidURIError (Hostname not supplied: '')

It raises only with omit method.

When try to parse URL and use an object, everything works great:

u = Addressable::URI.parse("https://user:[email protected]").
u.path
=> ""

Addressable::URI.parse("https://user:[email protected]").omit(:scheme, :port, :user, :password, :host)

@noff what do you expect this to return?

This?

irb(main):009:0> Addressable::URI.parse("")
=> #<Addressable::URI:0x168 URI:>

Tested this myself with a few variants, seems to only trigger with username/password in the URL

irb(main):016:0> Addressable::URI.parse("https://foo.com").omit(:scheme)
=> #<Addressable::URI:0x1e0 URI://foo.com>
irb(main):017:0> Addressable::URI.parse("https://foo.com").omit(:scheme, :host)
=> #<Addressable::URI:0x1f4 URI:>
irb(main):018:0> Addressable::URI.parse("https://foo.com").omit(:scheme, :port, :host)
=> #<Addressable::URI:0x208 URI:>
irb(main):019:0> Addressable::URI.parse("https://foo.com").omit(:scheme, :port, :user, :host)
=> #<Addressable::URI:0x21c URI:>
irb(main):020:0> Addressable::URI.parse("https://foo.com").omit(:scheme, :port, :user, :password, :host)
=> #<Addressable::URI:0x230 URI:>
irb(main):021:0> Addressable::URI.parse("https://[email protected]").omit(:scheme, :port, :user, :password, :host)
=> #<Addressable::URI:0x244 URI:>
irb(main):022:0> Addressable::URI.parse("https://foo:[email protected]").omit(:scheme, :port, :user, :password, :host)

Addressable::URI::InvalidURIError (Hostname not supplied: '')

I wonder if this is a similar bug? (similar error as in #272)

irb(main):015:0> Addressable::URI.parse("https://foo.com").omit(:host)

@dentarg
It will be great if omit host won't raise error. Like this:

Addressable::URI.parse("https://foo.com/mypath").omit(:host).path
=> "/mypath"
