问题 Cannot connect remote REPL properly Here are the steps I do: Start local repl instance: lein repl Connect to local by remote repl instance(I do it through Intellij IDEA) After this, every output in code goes only in local repl, in remote one there are nothing What I need: to see all outputs in both repl instances I have found partial solution, this code rebinds output of one repl to another. Just run it in remote one, and all output will go to it (defn rebind-output [] (prn "Rebinding output.

问题 I want to have a *flag* variable in a given namespace that is set to true only when :aot compiling. Is there a way to do that? 回答1: Your issue is kind of complicated because the definition of Clojure's own dynamic nature, so there's no rough equivalent of C's #ifdef or some other mechanism that happens at compile time, but here's a workaround: I created a Leiningen project with lein new app flagdemo . This trick detects when AOT is performed, as @Biped Phill mentioned above, using the dynamic

问题 I have an EDN configuration file in which the entries refer to existing functions, e.g.: :attribute-modules {:content {:class lohan.extractors.content/process} :schema {:class lohan.extractors.schema/process} :label {:class lohan.extractors.label/process} :user {:class lohan.extractors.user/process} :env {:class lohan.extractors.env/process}} Using clojure.edn/read-edn these entries are read as Symbols, but I want to be able to call them at runtime. The purpose of this is to provide a way for

问题 I had been using Clojure on emacs on my Bunsenlabs linux which was similar to Debian. Ones it stopped working. cider-jack-in command caused error. Could anybody help me to fix it?

Edit: ( cider-lein-command is lein ) 回答1: (from the comment) Looks like cider is looking for the clojure command, not the

问题 I'm new to Clojure and building a web app using the Noir framework (very similar to Compojure, in fact I think it's Compojure with a different request handler layer).
