nrebl.middleware

Clojars Project

VERY ALPHA

The start of an nREPL middleware that will spy on an nREPL connection and capture the results of evaluation for browsing in REBL.

NOTE: REBL requires a commercial license if it's to be used for commercial work

Installation (tools.deps)

  1. Install clojure
  2. Install REBL to a known path
  3. Include some aliases either in your ~/.clojure/deps.edn or your projects deps.edn respectively. Note the :rebl-8 and :rebl-11 aliases are for running either on Oracle's JDK 8 (which bundles JavaFX) or OpenJDK 11 which doesn't.
{:aliases {
           :nrebl {:extra-deps {nrepl {:mvn/version "RELEASE"}
                                cider/cider-nrepl {:mvn/version "0.21.0"}
                                refactor-nrepl {:mvn/version "2.4.0"}
                                rickmoynihan/nrebl.middleware {:mvn/version "0.2.0"}}
          :main-opts ["-e" "((requiring-resolve,'cognitect.rebl/ui))" "-m" "nrepl.cmdline" "-i" "--middleware" "[nrebl.middleware/wrap-nrebl,cider.nrepl/cider-middleware]"]}
	  
           :nrepl {:extra-deps {nrepl/nrepl {:mvn/version "0.6.0"}}}
           ;; - see https://github.com/cognitect-labs/REBL-distro
           ;; - you need to download the REBL JAR (and update the local/root below)
           ;; - you need to be using Clojure 1.10 and either
           ;; - - Oracle JDK 8 -- use :rebl-8
           ;; - - OpenJDK 11 -- use :rebl-11

             :cider {:extra-deps {cider/cider-nrepl {:mvn/version "0.22.1"
                                  refactor-nrepl {:mvn/version "2.4.0"}}}}}}}}

Usage

Assuming OpenJDK 11:

clj -R:nrepl:cider:rebl-11 -A:nrebl

Or Oracle JDK 8:

clj -R:nrepl:cider:rebl-8 -A:nrebl

You should now be able to connect to your nREPL through your editor or via an nREPL client and have nREBL capture the evaluation of forms.

Installation (leiningen)

Assuming you're running a recent leiningen (2.9.1) follow the steps:

  1. Install REBL to a known path.
  2. Add the following to your ~/.lein/profiles.clj file in order to configure nrebl as part of your :user profile:
 :nrebl  {:repl-options {:nrepl-middleware [nrebl.middleware/wrap-nrebl]}
         :dependencies [[rickmoynihan/nrebl.middleware "0.2.0"] ;; set this to the latest nrebl version
                        [org.clojure/core.async "0.4.490"]]
         :resource-paths ["/Users/rick/Software/rebl/REBL-0.9.157.jar"] ;; set this to where your REBL jar is installed
         :injections [(require '[cognitect.rebl :as rebl])]
         }

 :user [:nrebl
        ;;:other-tool-profiles...]

NOTE: the above configuration stores all :nrebl config in a single profile which is then merged into the :user profile, which will be available in dev/repl environments. It is usually cleaner to do it this way as it makes it explicit what configuration belongs to each tool.

Usage (lein)

  1. Run lein repl and/or connect to nREPL with your Editor.
  2. Evaluate (rebl/ui) (the :injections should make this available in every namespace)
  3. The REBL UI should appear
  4. Evaluate more forms in the REPL, they should each then appear in REBL.

Help Wanted

There's lots that can be done to improve this. Help & suggestions welcome.
