Cider Issue?

[Alex Schroeder]

Hi all

I have used Emacs Live and Overtone once or twice and don't remember any issues. Today I pulled a new Emacs Live from git and – being such a newbie – trying to get everything to work again.

I followed the instructions about the repl from https://github.com/overtone/overtone and in my terminal, I can produce the demo sounds from that page.

Then I looked at https://github.com/overtone/emacs-live and noticed a few things.


1. It talks about using "lein2 repl" but apparently it works perfectly fine with just "lein repl". Perhaps a peculiarity of the distribution used – or maybe related to the error I'm seeing? Anyway, it seems to start just fine:

alex@Megabombus:~/src/insane-noises$ lein repl
nREPL server started on port 55071 on host 127.0.0.1 - nrepl://127.0.0.1:55071
REPL-y 0.3.5, nREPL 0.2.6
Clojure 1.5.1
...
user=> (demo 7 (lpf (mix (saw [50 (line 100 1600 5) 101 100.5]))
  #_=>                   (lin-lin (lf-tri (line 2 20 5)) -1 1 400 4000)))
#<synth-node[loading]: user/audition-synth 31>

No problem.


2. The instructions mention "M-x cider" but such a command does not (does no longer?) exist. I'm assuming "M-x cider-connect"? When I run cider-connect, I use "localhost" for the host and get offered "insane-noises:55071" as an option. cider-connect looks like the correct command.


3. I am immediately greeted by a lot of bold red text:

WARNING: CIDER requires nREPL 0.2.7 (or newer) to work properly

You can mute this warning by changing cljr-suppress-middleware-warnings.
WARNING: CIDER's version (0.9.1) does not match cider-nrepl's version (not installed)

The echo area also shows: "if: nrepl-refactor middleware not available! Did you remember to install it?"

I'm not sure what to do now… I'm guessing adding a dependency? I looked at https://github.com/clojure-emacs/cider-nrepl and now I have this:

(defproject insane-noises "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.6.0"]
                 [org.clojure/clojure "1.5.1"]
                 [cider/cider-nrepl "0.9.1"]
                 [overtone "0.9.1"]])

Something to add to https://github.com/overtone/overtone perhaps?
And restart the repl.

That gives some installation messages:

Retrieving cider/cider-nrepl/0.9.1/cider-nrepl-0.9.1.pom from clojars
Retrieving org/clojure/tools.nrepl/0.2.10/tools.nrepl-0.2.10.pom from central
Retrieving org/tcrawley/dynapath/0.2.3/dynapath-0.2.3.pom from central

nREPL server started on port 55174 on host 127.0.0.1 - nrepl://127.0.0.1:55174

But the message stays the same, because 0.9.2 > 0.9.1 – d'oh! :)

So I tried to fix it:

alex@Megabombus:~/src/insane-noises$ lein repl
Could not find artifact cider:cider-nrepl:jar:0.9.2 in central (https://repo1.maven.org/maven2/)
Could not find artifact cider:cider-nrepl:jar:0.9.2 in clojars (https://clojars.org/repo/)
This could be due to a typo in :dependencies or network issues.

So now I'm confused. What next?

Cheers
Alex

Hi Alex,

it’s possible that some docs are out of date. If you could send pull requests or just let me know where specifically things are bad, I can fix.

For now, could you try updating the deps in your ~/.lein/profiles.clj to:

:plugins [[cider/cider-nrepl "0.9.1"]
[refactor-nrepl "1.1.0"]]
:dependencies [[org.clojure/tools.nrepl "0.2.7”]]

Does that help at all?

Hi Sam

Yes! It worked. :)

Unfortunately I'm a total newbie when it comes to Clojure and Leiningen.

I did not  have a ~/.lein/profile.clj file before, when it worked.

I googled for an example of how to add the fragmented you posted and after some trial and error I use the following:

{:user {

 :plugins [[cider/cider-nrepl "0.9.1"]
           [refactor-nrepl "1.1.0"]]

 :dependencies [[org.clojure/tools.nrepl "0.2.7"]]
 }}

My latest restart of the REPL now produces the following:

alex@Megabombus:~/src/insane-noises$ lein repl
Retrieving org/clojure/tools.nrepl/0.2.10/tools.nrepl-0.2.10.jar from central
Retrieving org/clojure/tools.nrepl/0.2.7/tools.nrepl-0.2.7.pom from central
Retrieving org/clojure/tools.nrepl/0.2.7/tools.nrepl-0.2.7.jar from central
nREPL server started on port 55837 on host 127.0.0.1 - nrepl://127.0.0.1:55837
REPL-y 0.3.5, nREPL 0.2.7
Clojure 1.5.1

And in my Emacs, M-x cider-connect RET localhost RET insane-noises:55837 RET gives me a REPL without error message!

(use 'overtone.live)

(demo 7 (lpf (mix (saw [50 (line 100 1600 5) 101 100.5

]))
                  (lin-lin (lf-tri (line 2 20 5)) -1 1 400 4000)))

This produces the expected result. Great!

As for pull requests… I'm not so sure. I feel like a total newbie. :)

Thanks

Alex
