https://github.com/gfredericks/exact <-- is this the library to use for bigInt in cljs ?

Hey all... I'm trying out a boot cljs project using https://github.com/martinklepsch/tenzing 1. boot -d seancorfield/boot-new new -t tenzing -n test-project -a +rum -a +garden -a +test -a +dirac - ok 2. cd test-project - ok 🙂 3. start dev:

Bye for now!

- I hope I got the right channel, or should I put it on #boot ?

@kurt-o-sys why don’t you start first by not including +dirac and +test? and then add them one by one until it breaks

I cannot really help here, but you should be able to isolate the issue more precisely

sounds like a plan

also I briefly checked the template code and it looks like the dirac version is hard-coded here: https://github.com/martinklepsch/tenzing/blob/master/src/leiningen/new/tenzing.clj#L108 this could be another source of very sharp edges, v1.1.3 is about a month old and running it against latest canary could cause hard-to-understand compatibility issues, you should be always running latest dirac with latest canary or stick to particular versions: https://github.com/binaryage/dirac/blob/master/docs/faq.md#why-should-i-use-recent-chrome-canary-with-dirac-devtools

ok, nrepl works if dirac is not added... The Classpath conflict: org.clojure/clojure version 1.8.0 already loaded, NOT loading version 1.7.0 is still there

@darwin thx

@kurt-o-sys you can probably use boot show --pedantic to track down that conflict

let me try:

$ boot show --pedantic

Our open source learning group is hosting the free online webinar Essential Klipse this Saturday at 7 pm UTC. ClojureScript fundamentals will also be discussed. Everyone is welcome! http://discuss.thevalueoflearning.org/t/webinar-discussion-2-essential-klipse/39?u=jay

@martinklepsch: Any chance you have some time for some questions about OpenLayers and the cljsjs package for it? I'm trying to get it working with CLJS and I think I'm missing something fundamental in my understanding of how the GClosure files and externs interact.

@shaun-mahood hey

@shaun-mahood can try to help but never used it myself. Either way let’s take this to #cljsjs

Hi there 🙂 Just a quick question I’m not sure about: let’s say we have ns example.stuff.utils from project example. Which are available locations for the file declaring this ns? src-root/example/stuff/utils.cljs, src-root/example/stuff.utils.cljs, anywhere you want under the source root directory? is there any difference between clj and cljs on this point?

used to have to conditionally require clojure.pprint and cljs.pprint for cljs/clj in a .cljc file but now i can apparently just require clojure.pprint. 1. is that a trend that will continue? e.g. will I be able to do the same for cljs.spec? 2. why do they differ – is it because there are slight differences in how they work?

cljs compiler aliases clojure. namespaces to cljs.

oh, so i can do it with everything already

Anyone have a good workflow for writing tests with cljs.spec? I'm trying to incorporate some macros for conformance, but I keep getting a ton of warning and errors

I'll post what I have, maybe i'm missing something simple

Hello @benzap 🙂 Just as a notice, you might be willing to as this in #clojure-spec

I would, but i'm not sure if the problem is with spec, or just clojurescript not liking my macros

if I make a function 'is-conformed' within the same file as slider.cljs, it works fine

if I put it in a separate file, it doesn't work. I think i'm misunderstanding how macros are generated in clojurescript

sorry, I mean it doesn't matter if it's a macro or a function. I'll try a few more things, maybe i'm just brainfarting on something simple

so functions work, but the test doesn't show what's being tested. I want to use a macro so the body of the cljs.test/is macro is caught and displayed in the test output

so upon failure I can have a better idea of what test failed

However, when I use the macro listed up top, I get Use of undeclared Var fluch.devtests.slider/spec which refers to the spec parameter in is-conformed

Alright, so I brought it down to the smallest error case

https://i.imgur.com/sol2VdC.png

is that a single quote in test-macro or a syntax quote?

single quote

uh oh

x is not splicing there

haha thanks

I think that might be it

i've spent 2 hrs on this!

macros are hard 🙂

Thanks a lot for the help, it's working perfectly

How do I get the env from node-js? environ doesn’t seem to support cljs

@grav js/process.env

Thanks! Wouldn’t it make sense to make environ wrap it?

I’m sure PRs are welcome 😜

🙂

Before I get started, does it at all make sense?

lots of libs could benefit from porting to cljc

I don’t know about environ specifically, but you could probably open an issue and start the conversation with the maintainer

there might be some sharp edges to watch out for the the maintainer can help you deflect

using figwheel and garden, is it possible to have them both running with the same command?

at the moment I call figwheel from cider

but then launch lein garden separately

not the end of the world really but I guess there might be anotherway

also is there anything to see the test coverage of clojurescript code?

@bostonaholic good point

@grav if you make a macro that wraps environ you can call it from cljs

https://github.com/dbrenden/gracilius/blob/master/src/gracilius/core.clj here is an example

why to do or dynamically on each call, when you know (env kw) is a compile-time constant, you should do something like this IMO: https://gist.github.com/darwin/e64eeae5f4b698f559fc722b6860f612

thanks, i'll do that instead
