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

Assuming you're running a recent leiningen (2.8.3) 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-0.9.109.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.

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.

1. Install clojure
2. Install REBL to a known path
3. Setup your deps.edn

{:aliases {:nrepl {:extra-deps {nrepl/nrepl {:mvn/version "0.4.5"}}}
           :rebl {:extra-deps {
	                  org.clojure/clojure {:mvn/version "1.10.0-RC3"}
                      rickmoynihan/nrebl.middleware {:mvn/version "0.2.0"}
                      org.clojure/core.async {:mvn/version "0.4.490"}
     	              com.cognitect/rebl {:local/root "<PATH-TO-REBL-JAR>/REBL-0.9.108/REBL-0.9.108.jar"}}}
           :cider {,,,} ;; configure cider/nrepl deps here
           }}}}

clj -A:nrepl:cider:rebl -m nrepl.cmdline --middleware '[nrebl.middleware/wrap-nrebl cider.nrepl/cider-middleware]'

Then connect to your REPL, and run

(cognitect.rebl/ui)

You should now be able to evaluate forms and have REBL capture them.

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