Require fail on ns/in-ns created namespaces

Question

Just to report that the following does not work at the repl (in Clojure it does):

`
(ns first.namespace)
(def a 4)
(ns second.es)
(require 'first.namespace) ;; with :reload is the same
java.lang.IllegalArgumentException: Namespace first.namespace does not exist

I am available for investigating more and/or taking charge of the issue.

Confirmed using NodeJs repl:

`

To quit, type: :cljs/quit

I guess it is each repl-env with its -evaluate to be responsible for loading right? Can it be a proble of each and every **load-fn** out there?

Answer 4

_Comment made by: arichiardi_

I am analyzing `cljs.repl/load-namespace` and it looks like it handles only loading from sources:


line 178 @ clojurescript 1.7.158

 sources (cljsc/add-dependencies
                   (merge (env->opts repl-env) opts)
                   {:requires [(name ns)]
                    :type :seed
                    :url (:uri (cljsc/source-for-namespace
                                 ns env/*compiler*))})



The function `cljs.closure/source-for-namespace` is throwing the exception because of course it cannot find the sources for a manually created namespace.
An idea could be to change `cljs.closure/source-for-namespace` and return nil in case no sources can be found.
Then change `cljs.repl/load-namespace` to check for created namespaces when `souces` is nil.

Mike told me that the namespaces are not reified, so the next question is, is there an atom that contains all the created namespaces?

I am going to wait for input on this, when everybody has time of course.
