Re: namespace what?
Hello, Jay, Your email is not precise enough. What did you place in which files, how were the files named, how were they stored relatively to some root folder, and how did you start a REPL ? 2011/12/13 jayvandal s...@ida.net: I think I understand namespace and then I don't! I try to run this example (ns examples.core (use [clarity.component :as c])) (make :button The Button) I have programs stored in c:\projects\klarity.clj I have clojure stored in c:\clojure-1.2.1\clojure-1.21. I am running c:\cljr\clj-installer-jar I tried running (ns clojure-1.2.1.clojure-1.2.1.src.clojure.core (use [clarity.component :as c])) (make :button The Button) What is namespace suposed to point to or access??? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: namespace what?
You can just say: (ns examples.core (:use clarity.component)) This will intern all the symbols in the clarity.component namespace into examples.core, so you can use them as if they were defined in examples.core in the first place: (make :button the button) This has the disadvantage of potential clashes, if a make function existed in examples.core, it would be overwritten. You can also say: (ns examples.core (:require clarity.component)) This makes the clarity.component namespace symbols available to you, but you still have to fully qualify them: (clarity.component/ make :button the button) This is a bit long-winded, so you can alias the namespace to something shorter: (ns examples.core (:require [clarity.component :as c])) In which case your code becomes: (c/make :button the button) So you manage to be concise, but also you keep your namespaces tidily separated :-) Stathis On Dec 13, 9:50 pm, jayvandal s...@ida.net wrote: I think I understand namespace and then I don't!

Oh, and of course Stathis is correct. `use' has no :as clause, so you probably want to `require'. (ns examples.core (:require [clarity.component :as c])) Bye, Tassilo -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: namespace what?
you are mixing up the format for ns. If you want to use an alias for your library, use require, like this: (ns examples.core (:require [clarity.component :as c])) ;; you can call the function/macro make, by using the alias. (c/make :button The Button) but if you don't want to use an alias and just introduce the vars from the library to your namespace, the use use: (ns examples.core (:use clarity.component)) (make :button The Button) Notice that while using the form ns the internal calls to library like use,require,import,... are actually keywords and not actual calls to the forms use,require,import which you can use outside of the ns form. I don't know if I explained myself well. It's been a while since I dive into clojure, but I am coming back again. I would recommend clojuredocs [http://clojuredocs.org/clojure_core/clojure.core/ns] On Dec 13, 3:50 pm, jayvandal s...@ida.net wrote: I think I understand namespace and then I don't!

Re: namespace what?
Do you have a complete program that you are trying to get working, along with errors? The examples.core namespace was chosen at random; you could call it whatever you want. It refers to the namespace in which your main program runs. In order to have clarity.component recognized, you need to manage your classpath and dependencies. The easiest way would be to create a project with lein, edit the project.clj, then run lein deps. Clarity is in the clojars repository, so it will pull it in automatically for you and place it in the classpath.
