the slime repl is a split repl, stdin/stdout are connected to emacs which processes the io and then sends it on to a separate java vm. the standard clojure repl connects stdin/out directly to the java vm. the debug-repl also works this way. so the debug repl can't be used with the slime repl directly, but only through the *inferior lisp* buffer. that's why Hugo Duncan enhanced the slime repl to be similar to the debug repl, but you have to use swank/break for that. > > 2) Start emacs, run M-x swank-clojure-project. > From the *inferior-lisp* buffer run: > user=> (use 'alex-and-georges.debug-repl) > nil > user=> (let [c 1 > d 2] > (defn a [b c] > (debug-repl) > d)) > (a "foo" "bar") > #'user/a > user=> dr-1-1001 => (+ 2 3) > 5 > dr-1-1001 => b > "foo" > dr-1-1001 => c > "bar" > dr-1-1001 => (quit-dr) > alex_and_georges.debug_repl.proxy$java.lang.Exception$Enumeration > $f482e887 > dr-1-1001 => b > "foo" > dr-1-1001 => c > "bar" > dr-1-1001 => (exit-dr) > java.lang.Throwable: Exiting back to main repl from debug-repl > dr-1-1001 => b > "foo" > dr-1-1001 => c > "bar" > dr-1-1001 => > > so it seems I can't escape back to the main repl. this is a bug in the debug-repl's quit and exit routines, which i hadn't noticed before because i always use the empty list, () , to exit. Try that. ctrl-d also works, but is a little dangerous because you risk exiting all the way out of the original repl. > > 3) From a shell run: > krukow:~/workspaces/trifork/intrafoo_clj$ lein swank > Listening for transport dt_socket at address: 8030 > WARNING: group-by already refers to: #'clojure.core/group-by in > namespace: clojure.contrib.pprint, being replaced by: > #'clojure.contrib.pprint/group-by > user=> Connection opened on local port 4005 > #<ServerSocket ServerSocket[addr=localhost/ > 127.0.0.1,port=0,localport=4005]> > > start emacs and M-x slime-connect > From *slime-repl clojure* buffer, run: > ; SLIME 20100404 > user> (use 'alex-and-georges.debug-repl) > nil > user> (let [c 1 > d 2] > (defn a [b c] > (debug-repl) > d)) > (a "foo" "bar") > dr-1-1001 => 2 > user> > > it seems to immediately quit the debug-repl (not sure why it writes > 2). again, use the empty list. > > 4) From a shell start a regular repl.

I want to see if it has the same problem, because I use it all the time and have never seen that problem. I'm trying to determine if the bug is only in swank/break, or in the debug-repl too. (I'm also trying to make people aware of the various combinations/options available.)
