If you create a namespace with associated vars interactively in the repl, and
subsequently try to use that functionality in other namspaces with
clojure.core/use, an exception is thrown:
FileNotFoundException Could not locate cljsh/docs__init.class or
cljsh/docs.clj on classpath: clojure.lang.RT.load (RT.java:430)
I can understand that no file can be located as there is none…
clojure.core/require throws the same exception (as it seems to use the same
clojure.core/load-libs under the cover).
Stand-alone, clojure.core/refer does work, however.
If I read the docs for clojure.core/require, it is clear that it has to do with
loading of code in files.
However, from a usability point of view, wouldn't it make more sense to let
clojure.core/require just return nil and do nothing if the namespace is already
loaded (unless the :reload option is give). Not sure why require actually
checks without any :reload directive… if the namespace is already loaded, and
the associated lib-files can be found, it's not supposed to do anything anyway,
if I understand it well.
Or maybe I miss some of the subtleties between a lib and a namespace as
concepts and implementations (?).
