Are there any static analysis tools for cljs yet to find things like unused bindings and otherwise dead code?

eastwood and yagni don't seem to have cljs support as of yet

unrelated question: has anyone had any luck with phantom js for their test runner?

i'm finding a number of annoyances with it

1. the (testing "...") string for a failed test is not outputted, making it pretty pointless to include at all 2. unable to do more than 1 async test in a (deftest) 3. poor error output on exceptions being thrown in tests, but there appears to be an issue for this already: https://github.com/crisptrutski/boot-cljs-test/issues/59

How do you build the clojurescript compiler on Windows?

Hmm.. is double-bundle style still the way to go for integrating / experimenting with npm libraries?

Or, really, if I want to live on the bleeding edge, is :npm-deps viable for non-node.js cljs?

Oh, it works 😄

ah damn, this js module relies on builtins (events, util)… not sure how to get around that .. seems browserify / webpack inject shims when they’re required

gross

Hi! I'm using Spacemacs and opened two repl processes: 1- jvm, 2-cljs +figwheel. When I send cljs S-exp to REPL I got a stacktrace, cause S-exp is evaluated in JVM repl. How to send CLJS S-exp to appropriate repl?

@minikomi you can probably make it work by explicitly adding the shims you need no?

tried adding them to npm-deps but didn’t seem to be able to get it to work.. moved on to another similarly-purposed library instead

How to access this in a js react-component from a Rum component? I’ve dropped a gist of the problem here: https://gist.github.com/gmp26/619b8bbf0be2244f151e4c5cee01f4bb

Out of interest, what does setting goog.DEBUG to false actually do?

AFAIK various bits of closure library get elided by setting it

https://github.com/google/closure-library/blob/0af16e41fb8026d990cadd024d48aefa7e784e36/closure/goog/base.js#L201-L210

you can also use it in your own code to elide some stuff in non-debug builds, this eliding is done by closure compiler, nothing to do with cljs compiler

I prefer to use macros in cljs (when I have full control over the code and it is in ClojureScript), it is more predictable

Ah, thanks @darwin

@weavejester you can use code like this in cljs macros to detect :advanced mode build: https://github.com/binaryage/cljs-oops/blob/dcf6ef5f55ed858016fdd7554adc631dda11e614/src/lib/oops/config.clj#L21-L23

@darwin macros as opposed to closure-defines?

@naomarik yes, a macro can decide what cljs code to emit based on compiler options

In enfocus, is it possible to use (at ... (html-content ...)) but have the current html-content available?

As in I have five divs with the same class, and for each want to read, transform and store the content back into the div

Not sure if this has been discussed. As of Firefox 54 Dirac/Devtools should now work in Firefox 🎉

@dominicm sounds like a science fiction to me 🙂

@darwin I'm sure you can also use the fact there's an additional sidebar api added if Fx. https://hacks.mozilla.org/2017/06/firefox-54-e10s-webextension-apis-css-clip-path/

Oh wait. The sidebar api is completely separate from the devtools api 😆

Dirac is not going to work, I cannot imagine this could be possible except for Firefox to use Chromium codebase and change the icon 😉

cljs-devtools maybe, if they implemented custom formatters feature from Chrome

doesn't look like this could happen anytime soon: https://bugzilla.mozilla.org/show_bug.cgi?id=1262914

Hi, basic question:

I created a new reagent project, started lein figwheel, could see the page.

wanted to add a new route that invokes a new component

added the following :

(defn simple-component [] [:div [:p "I am a component!"] [:p.someclass "I have " [:strong "bold"] [:span {:style {:color "red"}} " and red "] "text."]])

(secretary/defroute "/simple" [] (reset! page #'simple-component))

expecting to see the output when I visit localhost:3449/simple

but, seeing Not Found.

tried by rerunning figwheel, but, same issue

That's client side routing, not server side

You should probably have a link that points to specified route

@roman01la Thank you. I found a handler.clj in which I added the following and now I see the page.

(GET "/simple" [] (loading-page))
