to nrep...@googlegroups.com

Basically, I get a error when I try to follow the directions at http://ianeslick.com/2013/05/17/clojure-debugging-13-emacs-nrepl-and-ritz/ . In my init.el, I get a error when evaluating:

(require 'nrepl-ritz) ;;after (require 'nrepl)

the error is:

Debugger entered--Lisp error: (void-variable nrepl-mode-map)

byte-code("\302 \303\304#\210\302 \305\304#\207" [nrepl-interaction-mode-map nrepl-mode-map define-key [3 134217844] nrepl-ritz-threads [3 134217844]] 4)

require(nrepl-ritz)

eval((require (quote nrepl-ritz)) nil)

eval-last-sexp-1(nil)

eval-last-sexp(nil)

call-interactively(eval-last-sexp nil nil)

clearly, it has no idea what nrepl-mode-map is. Why this is I do not know.

The rest of this message is just all the things I could think of that you might ask, and the contents of my init.el and profiles.clj file. If you know what problem I am having already, there is no reason to read it. I am just trying to preemptively guess what you will ask.

This is the warning when I start up emacs:

Warning (initialization): An error occurred while loading `/home/stephen/.emacs.d/init.el':

Symbol's value as variable is void: nrepl-mode-map

To ensure normal operation, you should investigate and remove the

cause of the error in your initialization file. Start Emacs with

the `--debug-init' option to view a complete error backtrace.

My emacs version is:

If I run "lein ritz-nrepl" in my project, I get no particular errors, it says:

nREPL server started on port 50129

After doing the above, if I go to emacs and try to nrepl to 127.0.0.1:50129, it just hangs and the ritz-nrepl terminal prints:

[WARNING] No nREPL middleware descriptor in metadata of clojure.core$comp$fn__4154@7e090a0a, see clojure.tools.middleware/set-descriptor![WARNING] No nREPL middleware descriptor in metadata of clojure.core$comp$fn__4154@47b8c9d1, see clojure.tools.middleware/set-descriptor![WARNING] No nREPL middleware descriptor in metadata of clojure.core$comp$fn__4154@34c9dd20, see clojure.tools.middleware/set-descriptor![WARNING] No nREPL middleware descriptor in metadata of clojure.core$comp$fn__4154@30d47af3, see clojure.tools.middleware/set-descriptor![WARNING] No nREPL middleware descriptor in metadata of clojure.core$comp$fn__4154@4dd40090, see clojure.tools.middleware/set-descriptor!ERROR: Unhandled REPL handler exception processing message {:id 2, :op clone}
