REPL in Cursive

Normally, Cursive makes use of nREPL, but doesn't support nREPL's {:status :need-input}. (See cursiveclojure/cursive#358.)

Thus, if you start Ambly using

(repl/repl (ambly/repl-env))

you will see

Choice: DEBUG: unknown status need-input.

There are two ways to avoid this:

Use clojure.main REPL

With Cursive 0.1.51 or later you can choose "Use clojure.main in normal JVM process" when configuring the Cursive REPL. Then, you can start Ambly using

(require
  '[cljs.repl :as repl]
  '[ambly.core :as ambly])

(repl/repl (ambly/repl-env))

Use Piggieback

With Piggieback, you can use nREPL (but you will not be able to control which device Ambly connects to):

1. Add [com.cemerick/piggieback "0.2.0"] to your project dependencies.
2. Ensure you explicitly pin a later nREPL implementation by including the following in your project.cl (workaround for a Leiningen issue): :profiles {:dev {:dependencies [[org.clojure/tools.nrepl "0.2.10"]]}}
3. Mix in the Piggyback middleware by adding :repl-options {:nrepl-middleware [cemerick.piggieback/wrap-cljs-repl]} to your project.clj.
4. Issue the following two forms in the Cursive REPL

(require
  '[cljs.repl :as repl]
  '[cemerick.piggieback]
  '[ambly.core :as ambly])

(cemerick.piggieback/cljs-repl
  (ambly/repl-env :choose-first-discovered true))

The above will cause Ambly to connect to the first discovered device. (The menu that allows you to choose a device relies on the ability to call read-line, which isn't supported owing to the current lack of support for nREPL {:status :need-input}.)
