Having issues with cider-nrepl 0.11.0-snapshot + boot + cljs-repl

[samedhi]

I am using boot, I can correctly cider-connect to my boot repl. I can also start up a cljs repl by typing (start-repl) within cider-repl. I can confirm that this does work because I can see the results of the following:

boot.user> (start-repl)
<< started Weasel server on ws://127.0.0.1:60722 >>
<< waiting for client to connect ... Connection is ws://localhost:60722
Writing boot_cljs_repl.cljs...
 connected! >>
To quit, type: :cljs/quit
nil
cljs.user> (+ 2 3)
5
cljs.user> (js/alert "hello”) ;; The js alert dialog popped up
nil

However, I can’t do any actual cider commands. C-x C-e for instance returns

user-error: `cider-eval-last-sexp' needs a Clojure REPL.
If you don't know what that means, you probably need to jack-in (`C-c M-j’).

Therefore I have downgraded cider-nrepl from [cider/cider-nrepl “0.11.0-snapshot”] to [cider/cider-nrepl "0.10.2”]. The cljs repl now seem to work again, though naturally I am now getting CIDER's version (0.11.0-snapshot) does not match cider-nrepl's version (0.10.2). Things will break!

However, I can’t do any actual cider commands. C-x C-e for instance returns

Is that on a Clojure, ClojureScript, or ClojureC file?

[samedhi]

C-x C-e is on a cljs file. I am free to work all of cider's magic before calling (start-repl), it is only after calling (start-repl) that it does not seem to think it has a clojure repl.

[samedhi]

Also, I seem to again have the same errors with cider-nrepl 10.2.0 . I know I had it working for a few hours (I have been working in cljs for the last few), but somehow it has stopped working again upon reboot... 😞

[Malabarba]

@samedhi When you run (start-repl) you turn that Clojure REPL into a ClojureScript REPL. If that was your only REPL, then you no longer have a Clojure repl.
That's why CIDER says you don't have a Clojure REPL.

The issue here seems to be that you get this message in .cljs files. When you type C-x C-e in a .cljs file, CIDER should look for a ClojureScript REPL (which you do have), instead of complaining about the lack of a Clojure REPL.

---

I'll check if there's anything wrong with the logic. But the message you're getting wasn't even implemented in version 0.10.2, so it would be good to check if you have your versions right.

[samedhi]

Sorry, yes, I put it back to 0.11.0-snapshot, as that seemed to be a false start.

M-x cider-version => CIDER 0.11.0snapshot (package: 20160218.247)

Just to start things off, here is the task I am trying to run

(deftask development
  "Launch Immediate Feedback Development Environment"
  []
  (comp
   (serve :reload true)
   (reload)
   (watch)
   (cljs-repl)
   (cljs)
   (target :dir #{"target"})))

here is my profile.boot

(require 'boot.repl)

(swap! boot.repl/*default-dependencies*
       concat '[[refactor-nrepl "2.2.0-SNAPSHOT"]
                [cider/cider-nrepl "0.11.0-SNAPSHOT"]
                [org.clojure/tools.nrepl "0.2.12" :scope "test"]])

(swap! boot.repl/*default-middleware*
       concat
       '[[cider.nrepl/cider-middleware]
         [refactor-nrepl.middleware/wrap-refactor]])

[Malabarba]

Don't you need clojurescript as a dependency somewhere?

Hi there. I'm trying to reproduce the problem, but I can't get a repl going (even without CIDER).
I get an exception right after the << waiting for client to connect ... (see below).
If I run boot development (instead of boot repl) I also get an exception (albeit different).

Do you know what I might be doing wrong?

[samedhi]

Shoot, yeah, I had export BOOT_EMIT_TARGET=no set in my .bash_profile | .bashrc

I don't think that is the issue though.

[Malabarba]

Yeah, I still have the issue. Maybe weasel hassome external dependency?

[samedhi]

https://github.com/samedhi/cljsreplerror

This is a project where the error occurs for me.

[arichiardi]

I confirm that the error occurs for me in replumb as well, where I cannot evaluate (using C-c C-c) any form from a .cljs file in a Clojurescript REPL started with figwheel and (start-repl). Available for debugging 😉

[arichiardi]

Oh I forgot to say that I am using either lein repl to start it or jack-in. The result is the same. Same thing if I jack-in for Clojure + Clojurescript repl.
