Ya know...just going back to a previous version sounds much simpler.

so @boogie666 we need to find cider.el

if i go to the .clj file and do same i did before i can find the cider--connected--handler function

awesome. that means cider was loaded

problem is that pressing "enter" does not open it

ok. are you in that function definition now?

no

open what?

the function definition

it just shows up in the window

wait

see here

https://imgur.com/2H9gbdR

cool. visit that function

pressing "enter" with the function selected does nothing

are you sure you have that function selected? maybe just try to find-function on cider-mode or something similar

we just want to get into that directory somehow

if emacs helps us get there easier just taken any avenue

actually it says Symbol’s value as variable is void: helm-bookmark-map

ah ok. so something is going wrong with helm

sry

no biggie

i'm new here 😛

no problem at all

well, welcome to emacs, where things usually work nicely and often dont 🙂

😄

can you visit ~/.emacs.d/

we can just root around for the downloaded source

ok

ever used dired before?

one sec i'll try to find cider

no

ok. do spc spc dired and it'll ask you which directory and let's go to ~/.emacs.d/

navigate as normal, hit enter to go to directory or file, and hit ^ to go up a directory

we'll root around until we find the elpa directory

found elpa

awesome! search for cider, should be a directory like cider-23423423423432 something like that

go to that directory and we want cider.el

ok, i'm there

awesome. now search for cider--connected-handler

found it

(defun cider--connected-handler ()
  (let ((cider-enlighten-mode nil))
    (cider-make-connection-default (current-buffer))
    (cider-repl-init (current-buffer))
    (cider--check-required-nrepl-version)
    (cider--check-clojure-version-supported)
    (cider--check-middleware-compatibility)
    (cider--subscribe-repl-to-server-out)
    (when cider-auto-mode
      (cider-enable-on-existing-clojure-buffers))
    (sleep-for 0.1) ;; <-- Increase timeout till it works 
    (cider--debug-init-connection)
    (run-hooks 'cider-connected-hook)))

so there's a line (when cider-auto-mode ...

we want to put in a sleep expression right after that

ok

the bug has to do with loading classes not being done yet when we try to invoke it

so we're just giving time for the jvm to finish its thing (i think)

so add in that line (sleep-for 0.1) or longer if you want to be extra safe

ok, let me test it out

did you re-evaluate the defun?

i restarted emacs 🙂

we modified the source code but we need to eval it

ah well, that should do it

you're now an elisp programmer 🙂

yey 🙂

it worked 🙂

your editor is super extensible. and you obvoiusly like lisps

💋 💋 💋

awesome. haha you're super welcome

thx a lot

no problem

i've been using atom with proton-mode so far and thought i'd give spacemacs a try for a little bit 🙂 looks like i'm back in business 🙂

good. sorry for the hiccup. but emacs is super great and has really been nice. its so nice that its just an elisp ide that happens to edit text pretty well

everybody keeps saying that emacs is great OS, it just needs a good text editor 😛

for sure. and understandably people love vim interaction so spacemacs has got a lot going for it

anyway, thx a lot

for sure. happy coding

cheers 🙂

anyone having this issue?

nREPL server started on port 56754 on host :: - nrepl://:::56754

ah I'm not the only one apparently https://github.com/clojure-emacs/cider/issues/2092

See the conversation above. It's how to introduce a temporary fix

@andrea.crotti

yes ok that makes it works, thanks @dpsutton

I'll keep that around until there is another fix of some sort

awesome. if you are feeling more investigative, there's a patch to nrepl you can try and report if that fixes

you need to clone a fork of cider-nrepl and lein install it. takes substantially more work so not necessary if you're trying to get other things done

ah yes ok I'll see it if fixes it, however it's not an OSS project what I'm working on now so would be maybe better to reproduce it on something I can show

understood. i'm in the same boat here

it depends on the dependencies from my understanding

mm odd now I tried to debug a function and I get

1. Unhandled java.lang.Exception
   Debugger not initialized!

don't think it's related but I've never seen that before, anyone knows what it could be the problem?

did you happen to clobber anything when editing that function?

(defun cider--connected-handler ()
  (let ((cider-enlighten-mode nil))
    (cider-make-connection-default (current-buffer))
    (cider-repl-init (current-buffer))
    (cider--check-required-nrepl-version)
    (cider--check-clojure-version-supported)
    (cider--check-middleware-compatibility)
    (cider--subscribe-repl-to-server-out)
    (when cider-auto-mode
      (cider-enable-on-existing-clojure-buffers))
    (sleep-for 0.1) ;; <-- Increase timeout till it works 
    (cider--debug-init-connection)
    (run-hooks 'cider-connected-hook)))

note the line right after is (cider--debug-init-connection)

Fwiw installing a new version of cider-nrepl per the instructions in the issue I reported fixes things so I no longer have an issue

mm well I didn't edit anything I just redefined it @dpsutton

if you didn't edit it, then you changed nothing. i'm not sure i follow. did you just paste the above or did you add the one line that fixes the problem: (sleep-for 0.1)?

@dpsutton I just copied that function in ielm

which evaluates it re-defining the original one

I prefer to do that than changing a file not under revision control

understandable for sure

then i'm out of ideas. assuming the above is correct. maybe past that into the elisp repl or whatever you are using and make sure all of the names are spelled correctly?

Is there a reason why cider-format-buffer won't work on large edn files?

what error are you seeing?

no error, it just doesn't format.

ah, strange

it's a file with a list of maps generated by pr-str.

there's a way to change the pretty printer. perhaps the one you have isn't good with your data. if its long strings or heavily nested maps perhaps?

I've been trying many "ways" for three years in cider, and still can't get a reliable formatting for edn files.

have you tried clj-format? https://github.com/weavejester/cljfmt

and apologies if i'm telling you something you've tried a long time ago

yes I have, cider includes it and I have my tab keybinding set to it.

i'm trying to remember how to see the nrepl traffic. i think the toggle function has been renamed

i wonder if its abandoning with some kind of message?

where can i see the logs?

M-x nrepl-toggle-message-logging maybe see what the call to format the edn is returning

http://hackingcider.com/posts-output/2017-04-30-eval-walkthrough/

that talks about how you can see what cider and nrepl are saying to each other

maybe there's some response coming back with more information than cider is displaying?

I get a response as "done"

(<--
  id             "95"
  session        "917da08e-ebb3-4e5e-8492-16bcaf6716e5"
  time-stamp     "2017-10-03 12:16:41.289718364"
  formatted-code "({:uri "chef_module", :name "chefnode1", :kind :chef_node, :..."
  status         ("done")
)

and the formatted-code will contain the payload

hmm

you can try this in your own cider: Create a map with three keys, repeat 500, and spit it using pr-str. Now, try to format it.

sorry i'll try this in about ten minutes

and is this lacking newlines between the structures? my worry is that this is long lines and guessing new lines running up against 20,000 characters in a row

every single editor does that for json, I don't see a reason not to provide a default in cider.

oh for sure. it should but i don't know if it does

that's what I'm trying to figure out, if it's an easy el script ... could copy that in my emacs ...

i think emacs might use pprint by brandon bloom by default. this is not simple code.

sorry i mean fipp

but i'm sure contributions are welcome

If your day job involves parsing large edn files (who doesn't do that :)) I'm positive that formatting and paredit navigation to edn structures is a massive help.

undoubtedly. just need one of those busy people to code something up 🙂

Seems like cider has been busy for years fixing other bugs 🙂

I'd like to help if you can point me to the right direction ....

looks like here

https://github.com/clojure-emacs/cider-nrepl/blob/master/src/cider/nrepl/middleware/format.clj#L33

How do I customize wrap-pprint-fn middleware?

i'm not sure what you mean

i think you choose your pretty printer in cider

(defun cider--pprint-fn ()
  "Return the value to send in the pprint-fn slot of messages."
  (pcase cider-pprint-fn
    (`pprint "clojure.pprint/pprint")
    (`fipp "cider.nrepl.middleware.pprint/fipp-pprint")
    (`puget "cider.nrepl.middleware.pprint/puget-pprint")
    (_ cider-pprint-fn)))

not sure if that's what you're asking about however

and you can see the middleware here reads the pprint-fn var set in the message:

defn pprint-reply
  [{:keys [pprint-fn session transport] :as msg} response]
  (with-open [writer (pprint-writer msg)]
    ;; Binding `*msg*` sets the `:id` slot when printing to an nREPL session
    ;; PrintWriter (as created by `pprint-writer`), which the client requires to
    ;; handle the response correctly.
    (binding [*msg* msg
              *out* writer]
      (let [value (cljs/response-value msg response)
            print-fn (if (string? value) println pprint-fn)]
        (print-fn value))))
  (transport/send transport (response-for msg :pprint-sentinel {})))

{:keys [pprint-fn]is how elisp and clj are connected

@pri did that answer your question? i didn't meant to spend a lot of time on irrelevant or things you already knew

Thanks @dpsutton What do I need to add in my config?

I have added fipp and ultra in ~/.lein/profiles.clj the past (no luck)

to change the var used (and i'm not totally sure this is actually used in formatting end) set the var cider-pprint-fn. in your init you can (setq cider-pprint-fn 'fipp) or use the customize menu

That didn't work.

The more important question--as I've run through this issue for three years, is: why is cider reluctant to provide a sensible default?

default for what?

formatting and navigating edn files.

i think it has built in to format edn? and it defaults to the clojure pretty printer.

maybe this is a bug for them? i dont' know

but as defaults go that's pretty sensible

honestly i bet this is one area where cursive really shines

a default that doesn't do anything is useless, IMHO

big data structures. emacs just isn't very good with long lines

i'm pretty sure we're in a "default doesn't do anything in this situation" type of situation

but i take your point

Thanks for your time. For now, it's Intellij for edn files ...

yeah. i'll bet it will excel at it. lodge an issue? i may not know enough to help you out and someone else can get you closer to your goal?

Can CIDER be configured to warn in case of a lein error? With a certain bug in my source code, lein repl tells me #error {:cause Unable to resolve symbol: Foo in this context ... }, then starts a REPL anyway with my project's namespace prompt. cider-jack-in just gives me the prompt, leaving it to me to discover that something is busted, then try to figure out what. Is there a better workflow than first running lein repl to make sure your project is qualified for cider-jack-in? Running Emacs 25.2.2, just installed CIDER today from Melpa-stable.
