Url-Resolver
UPDATE
I've noticed from this stackoverflow article that you can actually use Ruby's URI library to resolve paths:
absolute_uri = URI.join(page_url, href).to_s
This gem was created quickly as part of another project and I missed this fact.
require 'uri'
# The URL of the page with the links
page_url = 'http://foo.com/zee/zaw/zoom.html'
# A variety of links to test.
hrefs = %w[
http://zork.com/ http://zork.com/#id
http://zork.com/bar http://zork.com/bar#id
http://zork.com/bar/ http://zork.com/bar/#id
http://zork.com/bar/jim.html http://zork.com/bar/jim.html#id
/bar /bar#id
/bar/ /bar/#id
/bar/jim.html /bar/jim.html#id
jim.html jim.html#id
../jim.html ../jim.html#id
../ ../#id
#id
]
hrefs.each do |href|
root_href = URI.join(page_url,href).to_s
puts "%-32s -> %s" % [ href, root_href ]
end
#=> http://zork.com/ -> http://zork.com/
#=> http://zork.com/#id -> http://zork.com/#id
#=> http://zork.com/bar -> http://zork.com/bar
#=> http://zork.com/bar#id -> http://zork.com/bar#id
#=> http://zork.com/bar/ -> http://zork.com/bar/
#=> http://zork.com/bar/#id -> http://zork.com/bar/#id
#=> http://zork.com/bar/jim.html -> http://zork.com/bar/jim.html
#=> http://zork.com/bar/jim.html#id -> http://zork.com/bar/jim.html#id
#=> /bar -> http://foo.com/bar
#=> /bar#id -> http://foo.com/bar#id
#=> /bar/ -> http://foo.com/bar/
#=> /bar/#id -> http://foo.com/bar/#id
#=> /bar/jim.html -> http://foo.com/bar/jim.html
#=> /bar/jim.html#id -> http://foo.com/bar/jim.html#id
#=> jim.html -> http://foo.com/zee/zaw/jim.html
#=> jim.html#id -> http://foo.com/zee/zaw/jim.html#id
#=> ../jim.html -> http://foo.com/zee/jim.html
#=> ../jim.html#id -> http://foo.com/zee/jim.html#id
#=> ../ -> http://foo.com/zee/
#=> ../#id -> http://foo.com/zee/#id
#=> #id -> http://foo.com/zee/zaw/zoom.html#id
So consider this gem as deprecated.
