Clojurians Log v2

Just discovered Dirac, wow, am blown away. But I have an issue where I can see all the refers and aliases of the current namespace in the autocomplete menu, but when I try to access or use them, I get back undefined. Using the fully qualified symbols works just fine. Any guidance on how I can resolve this?

hi, this will be tricky diagnose over slack, it would be great if you could isolate it to minimal case and share your project

I would look into it

btw. do you use figwheel or some hot-reloading? autocompletion goes out-of-sync for hot-reloaded code

Yeah, I have boot-figreload as well

just make sure that you are seeing the problem after first full load without any hot-reloading

Yeah, that's the case

Will create a minimal repro :thumbsup:

FYI, this is the function which is used to “understand” aliases: https://github.com/binaryage/dirac/blob/master/src/implant/dirac/implant/analyzer.cljs#L32

it uses clojure.tools.namespace.parse

@adamrenklint wait, maybe you are not in proper namespace? did you use in-ns to switch? please follow https://github.com/binaryage/dirac-sample#hello-world

Yeah, definitely did that. A minimal repro comes in ~10 minutes, just finishing up the instructions.

@darwin here it is: https://github.com/adamrenklint/dirac-repro

thanks, going look into that right now

@adamrenklint having some problem running boot dev on my machine, clojure.lang.ExceptionInfo: Call to clojure.core/defn- did not conform to spec:

what is your boot version?

@darwin uploaded a file: https://clojurians.slack.com/files/U08E3BBST/F8ZNGQDM0/-.clj

Same as you 😕

it looks like something is wrong with generate-lein-project-file! in boot

I noticed my clojure updated recently (via homebrew), maybe they have some more strict specs included

Ok, let me install Clojure via Brew and see if I get the same error

ok, mine is at 1.9.0.315

brew info clojure

hm, I switched brew to 1.9.0.297 and still the same issue, so that is probably not the case

Yeah, I have 1.9.0.315 via brew now, and boot dev is still working

Need to lookup what this generate-lein-project-file! is, never heard of it before

here is the full error: https://gist.github.com/darwin/338e5eec68cf1ed0e7c516a45830fd7c

@darwin shared a file: https://clojurians.slack.com/files/U08E3BBST/F8ZN1RTNG/gistfile1.txt

I will try to disable spec checks for now

I should be able to disable it via clojure.spec.skip-macros, but setting it as env variable does not work for me

btw. no boot commands work, all throwing

I’m going to install it differently

not via brew

Hmm, weird

hm, no, even their one-liner installer script is broken for me

:poop:

this is definitely something about my machine, investigating

The only reference to the issue I find is here: https://clojurians-log.clojureverse.org/boot/2017-03-03.html

But yeah, sounds like your machine has other issues

the problem is how to force that fancy boot trace to show full paths

maybe I have some obsolete boot version lingering somewhere and it is using it

looking for a way how to disable it or at least change it to full paths

the problem is that generate-lein-project-file! does not conform to fn or macro specs, so it looks like old code or I have too recent specs or my specs are somehow confused

maybe by installing some dev version of clojure or something like that

It's weird, because the project I sent you has a boot.properties file, so the Clojure and Boot version used should come from there

Of course, the Boot loaded (a Go app, I think) is the one installed with Brew or by other means

Try deleting ~/.boot 😸

That's what I do when things get messy

Oh BTW, I have JDK9. Not sure how that would make a difference in any way, but mentioning it anyway

ok, removing ~/.boot fixed it

there was something fishy there I guess

:thumbsup:

I’m not familiar with boot, didn’t start using it, but I agree it is a better way than lein

ok, I confirm that your steps are reproducible here with my dev build of dirac

so I will be able to investigate

Ok cool, so I'm not crazy 😛

@adamrenklint I think the issue is in your REPL, normally you should do (require 'dirac-repro.core) before you in-ns into it

this way REPL would be generating code aware of all definitions in the namespace

but for some reason it does not work with your repl

I’m not sure what boot is doing there, but we should be able to run stanalone clojurescript repl driven by boot and test it there

btw. the code generated by the REPL can be seen in devtools unders Sources/left tree/dirac-repl

it looks like require in your REPL is broken and it does not read the file

on repl side

(require 'dirac-repro.core) followed by (in-ns 'dirac-repro.core) and then as-aliased generates dirac_repro.core.as_aliased javascript

it should generate dirac_repro.as_aliased javascript

When you say your repl, which piece are you referring to?

org.clojure/tools.nrepl?

Sorry, a complete noob when it comes to REPLs, so not much experience to draw from

A child of save->reload trying to evolve 🙂

I’m not sure here, because whole REPL situation is pretty huge mess, right now I have unloaded whole context out of my head

I wrote this piece, when I had it in my head 😉 https://github.com/binaryage/dirac/blob/master/docs/about-repls.md

I’m now goint to try the same thing in dirac-sample project, which is driven by lein’s repl machinery, and compare the behaviour

@adamrenklint ok, now I understand

the system works as expected, your only mistake was not using require

using namespace alias alone does not refer to the namespace javascript object, e.g. reagent or as-aliased alone is not treated as something meaningful

as-aliased/some-func will work

Ah ok

Thanks for digging into it, much appreciated!

I got confused by that namespace-only thing, I would also expect it to work

I'll boot up my large project and try it there

btw. figwheel’s repl is able to do those requires automagically for you, because figwheel knows about your cljs project (for hotloading) and is loading them anyways

but it is not easy to force dirac to use figwheel’s repl, that is very advanced setup

I described it here: https://github.com/binaryage/dirac/blob/master/docs/about-repls.md#dirac--figwheel

Ok, will read through that and play a bit 🙂

Is there a reference implementation of that setup somewhere?

https://github.com/binaryage/dirac-sample/blob/master/project.clj#L170-L196

it starts vanilla clojure REPL, inside it starts figwheel’s sidecar and Dirac Agent

Dirac should be able to detect this situation and talk to figwheel’s repl

Ok interesting, I'll give that a try tomorrow

Thanks a bunch for taking the time to help me!

I just tested it and it works here, running lein repl-figwheel instead of lein repl

then in dirac prompt dirac :fig shows fighweel status

dirac :ls shows all compiler sessions on server side

dirac :switch 2 switches to figwheel session in my case

from that point repl is aware of hot-reloaded code and requires are no longer needed

unfortunately dirac command in dirac prompt has broken formatting, some CSS went wrong, will fix this eventually
