url

This is a library that makes working with URLs in Clojure and ClojureScript a little more pleasant.

This is an up-to-date fork of cemerick/url. It's intended to be a drop-in replacement.

"Installation"

url is available in Clojars. Add this :dependency to your Leiningen project.clj:

[miikka/url "0.1.2"]

Usage

The cemerick.url/url function returns an instance of the cemerick.url.URL record type that allows you to easily work with each datum within the provided URL:

=> (require '[cemerick.url :refer [url url-encode]])
nil
=> (-> (url "https://api.stripe.com/v1/charges")
     (assoc :username "vtUQeOtUnYr7PGCLQ96Ul4zqpDUO4sOE")
     str)
"https://vtUQeOtUnYr7PGCLQ96Ul4zqpDUO4sOE:@api.stripe.com/v1/charges"

url will also accept additional paths to be resolved against the path in the base URL:

=> (url "https://api.twitter.com/")
#cemerick.url.URL{:protocol "https", :username nil, :password nil,
                  :host "api.twitter.com", :port -1, :path "/", :query nil,
                  :anchor nil}
=> (url "https://api.twitter.com/" "1" "users" "profile_image" "cemerick")
#cemerick.url.URL{:protocol "https", :username nil, :password nil,
                  :host "api.twitter.com", :port -1,
                  :path "/1/users/profile_image/cemerick", :query nil, :anchor nil}
=> (str *1)
"https://api.twitter.com/1/users/profile_image/cemerick"
=> (str (url "https://api.twitter.com/1/users/profile_image/cemerick" "../../lookup.json"))
"https://api.twitter.com/1/users/lookup.json"

The :query slot can be a string or a map of params:

=> (str (assoc *3 :query {:a 5 :b 6}))
"https://api.twitter.com/1/users/profile_image/cemerick?a=5&b=6"

Note that url does not perform any url-encoding of paths. Use cemerick.url/url-encode to url-encode any paths/path components prior to passing them to url. e.g.:

=> (def download-root "http://foo.com/dl")
#'cemerick.test-url/download-root
=> (str (url download-root "/"))
"http://foo.com/"
=> (str (url download-root (url-encode "/")))
"http://foo.com/dl/%2F"
=> (str (url download-root (url-encode "/logical/file/path")))
"http://foo.com/dl/%2Flogical%2Ffile%2Fpath"
