Developing a wee "learning app" with duct/component/figwheel, using emacs and cider, and I've hit a snag.
I want the sexy auto-reloading of code that figwheel provides, but as the good Weavejester says in https://github.com/weavejester/duct-figwheel-component/issues/1, that's not a port of the duct figwheel-component component. So I followed the suggestion of that thread and tried hawk. Only... okay, I added "start-watch" into dev/user.clj: (defn start-watch [] (hawk/watch! [{:watcher :polling :paths ["src" "dev"] :filter (fn [ctx e] (is-srcfile (:file e))) :handler (fn [ctx e] (println "File " (.getName (:file e)) "Changed") (reloaded.repl/reset))}])) This actually sorta works; it watches the directories and tells me if anything changes (is-srcfile just checks for .clj or .cljs extension so emacs temp files don't set off a cascade of resets). user> (start-watch) {:thread #object[java.lang.Thread 0x467d27f1 "Thread[Thread-67,5,main]"], :watcher #object[sun.nio.fs.WindowsWatchService 0x5957d994 "sun.nio.fs.WindowsWatchService@5957d994"]} user> So a watcher is set up. If I change user.clj and save it... well, nothing happens in my *cider-repl* frame, but in my *nrepl-server* frame, I get File user.clj Changed :reloading (user) java.lang.IllegalStateException: Can't change/establish root binding of: *ns* with set at clojure.lang.Var.set(Var.java:221) at clojure.lang.RT$1.invoke(RT.java:241) at clojure.tools.namespace.repl$do_refresh.invokeStatic(repl.clj:95) at clojure.tools.namespace.repl$do_refresh.invoke(repl.clj:82) at clojure.tools.namespace.repl$refresh.invokeStatic(repl.clj:145) at clojure.tools.namespace.repl$refresh.doInvoke(repl.clj:128) at clojure.lang.RestFn.invoke(RestFn.java:421) at reloaded.repl$reset.invokeStatic(repl.clj:53) at reloaded.repl$reset.invoke(repl.clj:51) at user$start_watch$fn__45776.invoke(user.clj:67) ... So hawk is obviously watching my source tree and calling my handler function, but when reloaded.repl/reset is called, something is blowing up. I can call (reset) directly in the *cider-repl* frame and it works fine. But I'm obviously doing something horribly wrong, and it seems like it should be quite easy. What am I missing here? Should this be done somewhere besides user.clj? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
