any good examples of a project using figwheel with just cljs?

Oliver George03:05:56

Interesting question. So you mean without something like re-frame. Just reloading namespaces etc.

Oliver George03:05:49

There's not too much to configure or get wrong. I'd say start with the figwheel documentation and try the lein template.

athomasoriginal12:05:05

very simple project: - latest CLJS - pure JS interop - latest figwheel - clj tool (replaces lein/boot for this project)

athomasoriginal12:05:20

When I have time, all the projects in this repo will be converted to a similar setup...although, for how I want these projects to be used, I will likely just use the clj --watch command and drop figwheel...otherwise, should be what you're looking for

theeternalpulse00:05:06

Thanks, I am starting cljs with shadow-cljs, but would like to know some of the other ways outside of the lein/boot env for getting a project up. Very cool

tianshu03:05:45

is the document of npm-deps has been removed from http://clojurescript.org?

tianshu04:05:19

@mfikes thanks, I think what i found is this: https://clojurescript.org/guides/javascript-modules#node-modules it's likely there're some pages about how to use javascript libraries.

andrea.crotti09:05:07

is there a way in a Clojurescript project (using also re-frame and integrant) to load a namespace dynamically?

andrea.crotti09:05:01

it works if I add a require in the cljs file (even if not on top) but not if I add inside a function

andrea.crotti09:05:34

the problem is simply that we have a cljc file with some specs that should always be loaded or funny things happen

joelsanchez09:05:36

I think the answer is simply "you can't", there's some info here regarding the (require outside of ns https://anmonteiro.com/2016/10/clojurescript-require-outside-ns/

joelsanchez09:05:10

anyway, if they need to be loaded, why can't you just require it in the ns form?

andrea.crotti09:05:40

yeah I think that's the real mistake, but it just contains specs and some not namespaced for some reason

andrea.crotti09:05:58

(like :something/blah instead of ::blah)

andrea.crotti09:05:21

so the proper fix would be to change that instead, thanks

mfikes12:05:11

@andrea.crotti FWIW, when you add a require in an ns form, the order is honored. So if you need specs to be loaded before some other namespace, you can control that.

Hi, did anybody face troubles with an ##Inf tag when compiling cljs? For example:

Parse error. primary expression expected
case ##Inf:
      ^
I’ve found some github/google topics so for, but none of them help. My clojure(script) deps are:
[org.clojure/clojurescript "1.9.908" :exclusions [org.clojure/tools.reader]]
[org.clojure/tools.reader "1.1.0"]
I also tried to use the latest clojuresctip complier but without any result.

dominicm14:05:49

@igrishaev I'm not sure which version of clojurescript introduced ##Inf, but that is worth checking 🙂

mikerod14:05:55

@igrishaev why are you changing the tools.reader version manually?

igrishaev14:05:38

@mikerod it was just another try. The original version of deps are:

[org.clojure/clojurescript "1.9.946"]

igrishaev14:05:26

But still, it doesn’t work. I have a feeling that some legacy version of tools.reader might be used due to multiple dependencies.

mikerod14:05:20

yeah, sounds like it

mikerod14:05:43

this was a common issue that came up with ##Inf was introduced though, probably can find some info out there

igrishaev15:05:13

@mfikes yes, I’ve been on that page. Do you know btw how to check what exact version of a library is used? I guess that something overrides tools.reader

mfikes15:05:54

The answer to that depends on which dependency management tool you are using. (`lein`, boot, clojure / deps.edn)

igrishaev15:05:05

It’s lein; I tried lein deps :tree but a bit confused with its output

mfikes15:05:22

lein classpath will show you the classpath you end up with

igrishaev15:05:21

let me check…

igrishaev15:05:11

I’ve just wiped the whole ~/.m2 folder and the problem has gone.

I'm trying to get :infer-externs to correctly recognize the method .createToken as an extern. My code is

(defn- submit [stripe card token-callback]
  (fn []
    (-> ^Promise (.createToken ^js/Stripe.stripe stripe card)
        (.then (fn [^js/Stripe.result result]
                 (let [msg (error-message result)]
                   (dispatch [::set-stripe-error msg])
                   (when-not msg (token-callback (.. result -token -id)))))))))
(set! *warn-on-infer* true) doesn't warn about it with the type hint, but when I build I get the error TypeError: $stripe$$.$createToken$ is not a function Any tips why type inference isn't working there?

dnolen21:05:48

@vinai did you try master? I fixed a few things around externs inference recently

vinai21:05:20

No, this is 1.10.238

dnolen21:05:29

give master a spin to see if it’s still an issue

dnolen21:05:36

I’ll probably cut a release this Friday

vinai21:05:54

I got it working with a manual externs file, but I'll try master now to see if inference works there.

dnolen21:05:02

great thanks much

dnolen21:05:32

if you can’t get it to work then that’s another thing for me to tweak, I was just recently working on it so I can add a new test case

vinai21:05:48

Can I depend on master in a leinigen project.clj?

vinai21:05:57

Got a pointer?

dnolen21:05:07

with a checkout yes - but it’s way easier with clj tool

dnolen21:05:23

just a make a deps.edn with your deps and build

dnolen21:05:31

Quick Start covers the details

vinai21:05:43

Okay, might as well try

darwin21:05:13

@vinai for ad-hoc clojurescript master testing with lein I usually delete particular version from ~/.m2, then clone clojurescript repo, edit project.clj there to match my version (`1.10.238` in your case) and do lein install, this should put clojurescript master in place of 1.10.238 on your machine.

darwin21:05:00

better not to forget about this, so you won’t report confusing bugs

vinai21:05:15

@darwin You clone it into the original place in ~/.m2?

alexmiller21:05:34

why not just edit the project.clj to a unique value (1.10.238.mine-1)?

darwin21:05:38

no, lein install in clojuescript repo will build clojurescript and install it locally into m2

alexmiller21:05:51

then use that value instead

alexmiller21:05:14

m2 repos should be like immutable y’know? ;)

darwin21:05:17

@alexmiller yes, that’s a better solution, but one more step 🙂

alexmiller21:05:33

until you mess it up and lose a day debugging it

alexmiller21:05:43

then it’s 1000 fewer steps

vinai21:05:43

let me try that - will be quicker than building up the deps.edn (even though I'm 1/3 done with that).

alexmiller21:05:07

(this is how I sometimes test local clojure builds btw)

alexmiller21:05:20

you can actually do even better if you’re doing deps.edn though

alexmiller21:05:29

by making an alias that uses :classpath-overrides to swap out the mvn jar for own local one

alexmiller21:05:14

{:aliases :dbg {:classpath-overrides "path/to/clojurescript.jar"}}

alexmiller21:05:19

if you always do your local build in the same place then you can put this in your ~/.clojure/deps.edn instead and then anytime you want to test with a local build, you can -A:dbg with 0 steps

Creating ~/.m2/repository/org/clojure/clojurescript/1.10.238-mine.1 worked fine, but when I try to build my project I get an java.lang.IllegalArgumentException: Not a file: jar:file:/Users/vinai/.m2/repository/org/clojure/clojurescript/1.10.238-mine.1/clojurescript-1.10.238-mine.1.jar!/cljs/util.cljc

vinai21:05:36

The file /Users/vinai/.m2/repository/org/clojure/clojurescript/1.10.238-mine.1/clojurescript-1.10.238-mine.1.jar does exist though.

vinai21:05:43

Back to deps.edn

alexmiller21:05:41

does jar tf /Users/vinai/.m2/repository/org/clojure/clojurescript/1.10.238-mine.1/clojurescript-1.10.238-mine.1.jar | grep util find util.cljc? maybe it’s not built right?

alexmiller21:05:47

well, ya got me

vinai21:05:38

Jup, it's here

vinai21:05:53

% jar tf /Users/vinai/.m2/repository/org/clojure/clojurescript/1.10.238-mine.1/clojurescript-1.10.238-mine.1.jar | grep util
cljs/analyzer/utils.clj
cljs/util.cljc

vinai21:05:58

Is infer-externs always enabled with when building with clj -m cljs.main --optimizations advanced?

vinai21:05:17

How can I supply compiler options?

darwin21:05:00

clj -m cljs.main --help opts you put after cljs.main are for cljs

darwin21:05:40

e.g. --compile-opts

vinai21:05:54

That helps!

vinai22:05:35

Error building classpath. Unknown coordinate type for org.clojure/clojurescript: {:git/url "", :sha "78753d376d5bfe9afd1dbb98eea15fd5bd312255"}

vinai22:05:18

Somehow I'm off track... I guess I need some sleep. Sorry I wasn't more helpful checking out master works, will give it another try with a fresh brain tomorrow.
