Quick question (which y’all have probably seen a ton of times but google yields few results): Any idea why trying to make use of NavigateIOS yields the exception “put reactNavSuperviewLink back”?

NavigatorIOS, rather

whoops, wrong channel. Sorry

@mfikes: macros are definable in KLIPSE

see: http://blog.klipse.tech/clojure/2016/03/26/messing-with-macros.html

But only for simple cases

For more interesting cases, it doesn’t work e.g. http://app.klipse.tech/index-dbg.html?cljs_in=(ns%20foo.core%24macros)%0A%0A(defmacro%20hello%20%0A%20%20%5Bx%5D%0A%20%20(prn%20%26form)%0A%20%20%60(inc%20~x))%0A%0A(foo.core%2Fhello%2012)%0A%0A(defmacro%20dbg%5Bx%5D%20(println%20%22form%3A%20%22%20%26form)%20%60(let%20%5Bx%23%20~x%5D%09%20(str%20%27~x%20%22%3A%20%22%20x%23)))%0A%0A%0A(dbg%20%27(map%20inc%20%5B1%202%2030%5D))%0A

How do you guys test macros? clojure tests "is" doesn't eval them?!

(deftest minimal
  (is (=(core/make-chart {:initial {}} [])
        (macros/defchart db))))

FAIL in (minimal) (:)
expected: (= (core/make-chart {:initial {}} []) (macros/defchart db))
  actual: (not (= {:nodes {:initial {}}, :transitions []} (core/make-chart {:initial {}} [])))

"expected: A = M, actual: eval(A) != A" :thinking_face:

Only info I found is: https://groups.google.com/forum/#!topic/clojure/nAybQ7tDgSw where Mr Sierra wrote "call the macro, the form of the macro is an implementation detail". That's what I did, without success

could you paste your defchart macro?

Hi all, I’m writing a Clojurescript app that (I think) needs a Clojure backend (it has to query a postgres database). I just want to run this code on my machine locally, I don’t need to deploy anywhere. How do I interact with that Clojure backend? Does the backend need an HTTP server like ring? Is there a simpler way? Any help majorly appreciated

@ccann: If I were doing it, I’d consider making a simple REST call to the backend, but with the data encoded using Transit. That way you can pass Clojure(Script) data back and forth painlessly.

I basically only need one-way server -> client transfer for this toy app

would transit be overkill @mfikes?

(I don’t know the syntax and I’m pressed for time and overload of learning new things)

overkill, hmm no

@ccann: I'd use Transit because it is easiest. (Easier than JSON encoding.) Invoking the API for any of the serialization libraries typically involves very little code.

okay I’ll check it out

This question feels stupid to me but I’ve never really written code that spans server to client like this before. A server is necessary right? even if I’m running both client-side and server-side code on my laptop I have to serve up content from clojure and consume it via some protocol like HTTP right?

@ccann: just as alternative, if you want a prepackaged framework, Luminous does already a lot of the things you wrote

IIRC edn is faster than transit for small loads.

Hi all. Can anyone point me to the current state-of-the art solution for i18n (translation) in the client (cljs)? All the packages I find are either abandoned or pre-release.

I am also considering using FormatJS, but it requires JS interop and depends on the availability of window.Intl in the browser, which Safari doesn't support

@vincentdm: is Google Closure i18n suitable?
