Clojure & ClojureScript REPL (emacs + cider + boot)

The boot task boot-cljs-repl provides a way to connect to a ClojureScript REPL which interacts with a running browser instance.

If properly added to the build.boot dependencies one can call the function (start-repl) from within a Clojure repl in order to start up a ClojureScript REPL.

I'm connecting to the clojure REPL from withing Emacs, by the help of the cider package with the function: (cider-connect)

I'm trying to figure out how to have a Clojure REPL and a ClojureScript REPL in two different Emacs buffers (at the same time). The procedure described above does 'replace' the later by the former.

Calling (cider-connect) again, tells me that there is already another REPL running.

I think the behavior I'm looking for was the default when using leiningen + cider-jack-in / cider-jack-in-clojurescript. Those calls seem to be only meant for leiningen.

So, I'm asking: What's the boot way of doing this?

When calling cider-connect again you should see a prompt:

REPL buffer already exists (*cider-repl localhost*).  Do you really want to create a new one? (y or n)

Just hit y and you get a new REPL buffer.

Same for cider-jack-in and cider-jack-in-clojurescript.
