Clojurians Log v2

ah, it works for dependencies in both, it's just my project's namespaces that I can't seem to require

@jbaiter: have you resolved that require problem? I believe this is nREPL thing, dirac just uses standard nREPL connection

nope, i haven't 😕

the standard figwheel cljs repl doesn't use nrepl, right?

not by default

you can enable it and try it there

add :nrepl-port 7777

that i will do, thank you!

and connect to it from Cursive or some other nREPL-enabled client

lein repl can also connect and act as nREPL client

see lein help repl

ah, i have that already enabled

but when I connect to the port I get a standard clojure/jvm repl

hmm, figwheel has some docs how to enter cljs repl via nREPL I think

https://github.com/bhauman/lein-figwheel/wiki/Using-the-Figwheel-REPL-within-NRepl#start-figwheel-repl-within-nrepl

(use 'figwheel-sidecar.repl-api) and `(start-figwheel!)

(use 'figwheel-sidecar.repl-api) and (start-figwheel!)

yup, that launches the regular figwheel repl that you get with lein figwheel, though

but maybe this is not what we want, we should try to start standard piggieback

right

i think for nrepl in clojurescript I need piggieback

but dirac uses a custom forked version, i think

ok, then follow piggieback + weasel docs

will do :simple_smile:

yes, dirac uses slightly modified piggieback, but features were added, not removed 😉

thanks for the work, btw, i *really* appreciate dirac and the custom formatters

thanks

the thing is I don’t fully understand this nREPL/piggieback stuff 😞

reading piggieback and clojurescript core REPL sources is hard for me

hehe, i'm with you

i find getting to grips with all of the tooling the hardest part about clojure/cljs

indeed, unfortunately I don’t see an easy way to fix this problem :simple_smile: too many moving parts and we are building on top of “foreign” platforms

whole lein/boot stuff has java legacy, and cljs stuff must respect underlying javascript ecosystem

it is nice when it works, but when something breaks in the platform below, it is too hard for most people to deal with it

precisely, leaky abstractions all over

same with error messages

it's really a testament to the language that i enjoy it as much as i do .)

well, some class of error messages is fixable (language-level errors/warnings)

some class of runtime errors from underlying platform is not fixable IMO

i think i'll leave that piggieback stuff be for tonight, ClassNotFoundException for piggieback, even though its in my classpath and in the dependencies

did you add it to :nrepl-middleware?

yep, tried it both in symbolic and string form, both times class not found

it's in :dependencies, too

hm, weird

do you use lein? what lein pprint says?

https://gist.github.com/jbaiter/68edf92fa69f2b89e5ac#file-project-clj-L101

pprint is not a task 😅

ah, add lein-pprint plugin

I have it in ~/.lein/profiles.clj

we want to see lein with-profile project/dev pprint :dependencies

wonder why you are adding [org.clojure/clojurescript "1.7.228”] into :plugins, that cannot work

tbh, most of the stuff in there is from the luminus template

piggieback is in there, when i run the command

so that ClassNotFoundException is raised from some init code? what if you try to require it directly from repl

I think (require ‘cemerick.piggieback)

hah, that works

so it is on class path, some code somewhere is trying to require something and raises ClassNotFoundException, can you investigate what code is responsible for it?

i think it's the anonymous function bound to start-repl

when i add the require to the init code it works

comment out that whole :init stuff in :repl-options

i copy-pastaed the code from the sample repository

and do it by hand

when your repl starts, boot your cljs.repl one command a time

(require 'cemerick.piggieback) (require 'weasel.repl.websocket) (cemerick.piggieback/cljs-repl (weasel.repl.websocket/repl-env :ip "0.0.0.0" :port 9001))

line-by-line

we will see where is the problem

IllegalStateException Can't change/establish root binding of: *cljs-repl-env*

3rd line?

yep, on the third line

wait a sec, I have figwheel running in the baackground, maybe that has something to do with it

mh, nope

wait I’ve seen this error before

I cannot recall when and where 😉

ah, it was clojure version

let’s see

that lein pprint command, what clojure version it displayed?

1.8.0

I see that you have 1.8.0, but it could be overriden by something else I guess

ok

that’s right

i found some issues on github, but those refer to piggieback 0.1

hah

ah, no

i thought i had an indentation error and :repl-options ended up inside of :cljjsbuild

but that was not the case

try to add [org.clojure/tools.nrepl "0.2.12”] into deps

ah, you have it there

try to comment out :main from the project.clj, line #44

nope

i'm afraid i have to call it a day now 😕

thanks for the help!

ok, good night

maybe a set of fresh eyes tomorrow morning will bring the solution .)

I think you will have to start commenting out pieces of that project.clj, it is pretty complex

yeah, that is an excellent idea

or maybe write a minimal one from scratch, just for repl

gn

you too!

and let us know how it went :simple_smile:

will do!
