how was the trick to make my buffer a clojurescript one?

I get the dreaded ...needs a ClojureScript REPL. If you don't know.... on cider 0.14.0

@richiardiandrea That means you’re trying to evaluate a Clojurescript statement in the Clojure REPL - you need to start a CLJS REPL, either with M-x cider-jack-in-clojurescript or by e.g. (cljs.repl/repl (cljs.repl.node/repl-env)) in your Clojure REPL

Yep I have done the second, but in boot, I thought there was a way to mark it 😁

cider just knows hehe

I tried clojurescript-mode with no luck ..Anyway thanks

cider "knows" because the repl receives stuff back from a cljs backend. when status comes back, it mentions cljs

as far as I'm aware, you evaluate things in "java" clojure code that invokes clojurescript middleware

for lein, this is done automatically and configured by you

but in boot, you have to setup your own task that does this

and the easiest that i've seen is this https://github.com/adzerk-oss/boot-cljs-repl

(deftask dev []
  (comp (watch)
        (cljs-repl) ; order is important!!
        (cljs)))

@richiardiandrea there is also cider-create-sibling-cljs-repl which you can configure yourself to run the command you would like, I use this to run (start-repl) with boot after I started my dev task in my clojure-repl

if you also use projectile you can even vary this command per project with a .dir-locals.el file per project

@dpsutton yep I do that already, still you need to call start-repl...Even after that I cannot evaluate code in the buffer

you invoked your task that invokes (cljs-repl)?

I will try to investigate today

Yep

and what happens after you do that?

You need task + invoke a function

After that I get to the cljs.user prompd

turn on toggling of the messaging

But every eval command gives me that error

nrepl-toggle...

and see if it sent back a status of "done" that also includes a repl type of "cljs"

Oh OK cool

you should see a session id of your clojure repl and then hopefully see a new session id for the clojurescript backend

> but every eval command gives me that error which error?

Ok thanks for the details I will check in a bit (on the bus to work now)

cool

is this by chance a cljc buffer?

It is: https://clojurians.slack.com/archives/cider/p1483491821001249

No cljc

ok

if you want to send me a link to a repo that can easily demonstrate the bug i'll look at it tonight

Ok Yes I have a repo, it is a bit hacky as I am porting figwheel to boot but it should work anyways

To be in the same situation you should grab the fighweel branch here: https://github.com/boot-clj/boot-figreload

And use the sample project here: https://github.com/arichiardi/fig-boot-reload

If it's too much work don't worry I will be checking that during the day

One thing is that if I copy and paste the form the repl (of course) works

@dpsutton it looks ok in the project above so I might actually need to try another demo project

so its working for you now?

yeah, see that "repl-type" "cljs"

that's what cider remembers and when its looking for a clojure script repl it goes on that value

so if you see that you should be good

mmm I don't know yet, let me try the other prj, but thanks I did not know that and now my debug can be more focused 😉

👍

hahaa didn'tknow there was a CIDER emoji

i like it

just found it 🙂

@dpsutton the problem solved by itself, magically

by the way it has to do with the execution/connection order

I have to launch boot, then connect to nrepl, then ((eval 'adzerk.boot-cljs-repl/start-repl)) in the repl buffer, then connect the browser to localhost:PORT

that… nearly makes sense to me

no yeah definitely makes sense 😧

just that after a couple of months of not using it, I probably forgot 😄

hi there

hi

I’m trying to debug a web app but I’m not sure how to go about connecting to the running webserver

I usually run it with a boot task, I thought I would be able to connect to it through cider-jack-in

but it spins up its own nrepl

is cider-connect and loading the app env myself my only option ?

If your web app starts its own nREPL server, then you can cider-connect to it and it will have the app env already set up.

oh right I thought I would have to load the env myself

thanks
