Clojurians Log v2

@superstructor: I deployed https://clojars.org/powerlaces/boot-cljs-devtools, can you give it a good as well please? version 0.1.1-SNAPSHOT

how was the shortcut to activate Dirac again? CTRL-PGUP ?

oh sorry I was using the standard panel all good

how can you evaluate forms? I pressing enter and it just adds a new line

no, it looks like evaluation does not work

@richiardiandrea: next version of dirac will support :preloads in the same way as cljs-devtools does

just need to push cljs-devtools v0.8 out and then focus on dirac polishing

@darwin I was trying to evaluate a form in Dirac but it was always adding a new line

both with and without Parinfer enabled

are you sure you were in dirac prompt? (green-ish background)

yeah there was a cljs.user green string showing up

ok, then follow this to see errors in dirac console: https://github.com/binaryage/dirac/blob/master/docs/faq.md#something-broke-how-do-i-debug-dirac-devtools-frontend

there should be some

or I can tell you how to enable verbose mode in nREPL middleware / dirac’s weasel server, so you can see if the eval command was really received by REPL backend and compiled and sent back to frontend for evaluation

when it does like this in clojurescript it means that it cannot parse the input form..

I can try to enable verbose mode, I am using boot-cljs-devtools btw

set env variable DIRAC_NREPL_LOG_LEVEL to “DEBUG” before launching your nrepl server

https://github.com/binaryage/dirac/blob/master/src/nrepl/dirac/nrepl/config.clj#L6

k

or pass that config explicitely via boot (more advanced)

export DIRAC_NREPL_LOG_LEVEL=DEBUG; boot cider dev is easy enough 😉

sure

there is also: https://github.com/binaryage/dirac/blob/master/src/agent/dirac/agent/config.clj#L19

and :weasel-verbose in runtime config: https://github.com/binaryage/dirac/blob/master/src/runtime/dirac/runtime/prefs.cljs#L13

booting

weasel is the component responsible for evaluating compiled clojurescript sent from nrepl server back to client

DIRAC_WEASEL_VERBOSE is also env var which could be set: https://github.com/binaryage/dirac/blob/master/src/runtime/dirac/runtime/prefs.clj#L34

uhm not really more verbose...

is boot cider dev really starting nrepl server?

yeah

Compiling {sass}... 2 changed files.
Adding :require adzerk.boot-reload.init10338 to main.cljs.edn...
nREPL server started on port 5088 on host 127.0.0.1 - <nrepl://127.0.0.1:5088>
Adding :require [devtools.core dirac.runtime] and :init-fns [devtools.core/install! dirac.runtime/install!] to main.cljs.edn...
Compiling ClojureScript...
• main.js

Dirac Agent v0.6.2
Connected to nREPL server at <nrepl://localhost:5088>.
Agent is accepting connections at <ws://localhost:8231>.
Elapsed time: 28.075 sec

hmm, looking into that

btw I moved the repo to https://github.com/boot-clj/boot-cljs-devtools

set both DIRAC_AGENT_LOG_LEVEL=debug DIRAC_NREPL_LOG_LEVEL=debug

it looks DIRAC_NREPL_LOG_LEVEL does not work for some reason or is not used (or it starts logging after dirac frontend connection or something)

I don’t remember the details

k

changed both env vars to “all” and this is my output for evaluation form (+ 1 2): https://gist.github.com/darwin/d75e8cba060b5765aaff14dc2df1613f

wow, I don't see any of that

so maybe your boot task does not propagate env variables to spawned subprocesses?

I’m using the environ library

https://github.com/binaryage/dirac/blob/master/src/agent/dirac/agent/config.clj#L19 https://github.com/binaryage/dirac/blob/master/src/lib/dirac/lib/utils.clj#L35-L38

it can be that, I think the task was originally built using the repl built-in task which I think executes in a pod

so I cannot debug...but without env vars I cannot evaluate as well?

no, you should be able to eval just fine

env vars are just alternative way how to configure dirac

in our specific case, we wanted enable verbose logging to see what is going on

this should be fixed in your boot task anyways, users should be able to configure dirac via env vars

all dirac env vars have DIRAC_ prefix if it helps

can you share the project? I could try to reproduce it here

wait, Chrome 50.x?

https://github.com/binaryage/dirac/blob/master/docs/faq.md#why-should-i-use-recent-chrome-canary-with-dirac-devtools

you must be using Canary, they did a lot of changes in devtools recently, v50 is too old

oh

lemme update

Chrome Canary is currently not available on the linux platform.
You can try Chrome Canary for Windows 32-bit, Windows 64-bit or OSX. 

bad luck

it was 😉

google-chrome-unstable should work

https://github.com/binaryage/dirac/blob/master/.travis.yml#L16-L19

trying

unfortunately bleeding edge version of devtools was pretty broken over last 14 days or so - they are adding support for node.js debugging announced on Google I/O

Version 54.0.2810.2 dev (64-bit)

oh wow cool stuff

i mean the node.js debugging

yeah

at least now we have an error

ok, this one was already reported by superstructor here in the channel, didn’t have time to look into that yet

ok no problem, at least now it evaluates it

Darwin thanks for your support and we discovered the env-var bug in boot-cljs-devtools 😉

I will open an issue with the above, I don't see it

yep, that should get fixed when you get time to dig into that, thanks

no hurry, time is limited, we try our best 😄

btw, the exception you are getting is from here: https://github.com/binaryage/dirac/blob/master/resources/unpacked/devtools/front_end/console/ConsoleView.js#L721

what was the form you tried to eval?

(println "test")

but any form throws

ok, it works for me here on Mac

maybe a discrepancy between linux and mac

although unlikely

so it might be a canary vs dev difference?

I’m using canary here

.11 currently

the link above installed Version 54.0.2810.2 dev (64-bit)

4.0.2811.0

54.0.2811.0

oh kk

might be that

but that won’t be the issue I guess

those versions are close enough

oh ok you are the expert in this 😉
