I'd like the bootstrap file to leave the REPL in whatever namespace I last specified with my in-ns. But I'm getting different (unexpected) results in two cases. Case 1: Slime: the in-ns is ignored (although expressions around it are evaluated), and my repl is in the user ns. Case 2: Command-line (java ... clojure.main -i ./bootstrap.clj -r) the repl prints user->, but is actually in the correct namespace (I can execute functions defined in that namespace directly, without explicitly in-ns from the repl command line). Any ideas how to get the repl to "start" in a different NS than user and why I'm seeing different behavior in my two cases?
The "-e" and "-i" initialization arguments to clojure.main run after the repl has entered the user namespace. In Clojure, every "load" saves and restores the current namespaces around the load, so only a "- e" argument can affect the initial namespace for a repl.
This should do what you're after: % java -cp clojure.jar clojure.main -e "(in-ns 'funky-ns)" --repl #<Namespace funky-ns> funky-ns=>Regarding your Case 2 where it appeared you were actually in a namespace other than the one shown in the prompt, that's very unlikely. *ns* is the "one" true place (in a given thread at a given time) where the current namespace is stored. Could it be some code you loaded "referred" to or "used" the non-user namespace thereby bringing its names into user?
