uri

A URI library for Clojure, wrapping the java.net.URI class.

Usage

Create a URI with:

=> (make "http://clojure.org/")
#<URI http://clojure.org/>

You can also create URIs by passing in specific attributes.

=> (make "http" "clojure.github.com" "/clojure/clojure.core.api.html"
"clojure.core/defmulti")
#<URI http://clojure.github.com/clojure/clojure.core.api.html#clojure.core/defmulti>

You can get individual attributes from URIs:

=> (scheme (make "http://clojure.org/"))
"http"
=> (host (make "http://clojure.org/"))
"clojure.org"

If a URI does not contain a particular attribute, they return nil. Note that this is different from the java library, which returns -1 for a missing port.

You can determine whether a URI is absolute with absolute? or opaque with opaque?:

=> (absolute? (make "http://clojure.org/"))
true
=> (absolute? (make "clojure/clojure.core.api.html"))
false
=> (opaque? (make "mailto:java-net@java.sun.com"))
true
=> (opaque? (make "http://clojure.org/"))
false

You can normalize a URI:

=> (normalize (make "docs/../clojure.core.api.html"))
#<URI clojure.core.api.html>

You can resolve or relativize a URI (see the javadoc):

=> (resolve (make "http://clojure.org/") (make "docs/clojure.core.api.html"))
#<URI http://clojure.org/docs/clojure.core.api.html>
=> (relativize (make "http://clojure.org/")
               (make "http://clojure.org/docs/clojure.core.api.html"))
#<URI docs/clojure.core.api.html>

You can create a URL from a URI:

=> (url (make "http://clojure.org/"))
#<URL http://clojure.org/>

You can swap between URIs and clojure maps:

=> (uri->map (make "foo://bar@baz:8000/foo?bar=baz#frag"))
{:fragment "frag", :query "bar=baz", :path "/foo", :port 8000, :host "baz",
:user-info "bar", :scheme "foo"}
=> (map->uri {:fragment "frag", :query "bar=baz", :path "/foo", :port 8000,
:host "baz", :user-info "bar", :scheme "foo"})
#<URI foo://bar@baz:8000/foo?bar=baz#frag>
