i have a question about js->clj and namespaced keywords: I try to use clojure.spec in my clojurescript app where i namespace all keywords that are map keys. {:url ""} is now {::url ""}. Most of my data i use in my app will be received as js-object, so i need to js->clj a lot. Now i need to namespace all those map keys. Is the only solution to write my own js->clj or do i miss something here? - maybe it is stupid to namespace all my map-keys? (js->clj jsobj :keywordize-keys true) is not namespaceing the keys.

i changed the js->clj to use a second param :ns. And i used a faster implementation by Darrick Wiebe. https://gist.github.com/ThomasDeutsch/667dc44cb301e646de76d92f54f921d1.

just released a new version of Chestnut with the latest ClojureScript and Figwheel

Has anybody used cljsjs/react-bootstrap "0.29.5-0" i.e react bootstrap components in reagent?

@rnandan273: I used react-bootstrap before

does anyone know how to access/dereference an atom from javascript?

@tomjkidd: do you mean dereference a ClojureScript atom from JS?

what is the context? Like from a deployed production ClojureScript web app or Node.js?

Yeah, that is what I'm talking about, I created a simple map in cljs and used an ^:export to create a function that lets me pull it in in js using the namespace from cljs

@tomjkidd: so you will need to export cljs.core.deref and anything else you might need

And its with a browser, debugging with chrome, I can see the object, its just hidden in obj.state.arr and I don't know how to access it with it's keys

ah, ok

then call them as plain js functions from js

Thank you.

@tomjkidd: goog.exportSymbol is what you want to use since you cannot go and add ^:export to things already defined

Ok, that makes sense. Thanks again

@tomjkidd: maps implements ES6 Map interface

but you do need to be able to construct keywords to get at things of course.

right, I can find a way, worst case I will use strings

This is a prototyping effort working with web audio

Garden CSS question: what is the syntax to generate this translate3d(0,0,0)?

@noprompt: ^^^

can't you just :transform "translate3d(0,0,0)" i.e put it in a string

seems to work fine for me

sure but I gave a simplified version

actually I want to use some vars and doing str is tiresome

I looked into Garden's unit tests https://github.com/noprompt/garden/blob/master/test/garden/def_test.clj

defcssfn is what I need

@myguidingstar: yep that's the one.

thanks for the fun you bring to CSS 🙂

@myguidingstar: it makes me happy to know people are still finding utility in the library. 🙂 i can't apologize enough for not doing a better job maintaining it. 😕

@noprompt: I find the library fantastic. Been using it for almost a year now 🙂

@noprompt: while you are here...what is the best way to add "!important" flags when using color objects?

@sbmitchell: well you wouldn't add it to the color. it'd be in the declaration e.g. [<color> :important]

{:color [:blue :!important]}

can :blue be replaced with rgb definitions?

sure

oh awesome

yeah. 🙂

ok I have been doing that wrong this whole time

heh

I was doing some nasty stuff around that...`{:color (str (as-hex v/light-gray) " !important")}` where v/light-gray is a rgb definition in a variables ns

my recommendation is to use the vector notation for declaration values all the time. in fact, i wish i would have made that the design from the start.

it's much easier to write functions, update declarations, etc. with the vector notation. imho.

@noprompt: Shouldn't it be {:color [[:blue :!important]]}?

@rauh: ha! yes! (i haven't worked on or with it in a long time!)

what's a good way to figure out which project i'm in?

@brian_mingus: can you clarify the question? what is this in relation to?

i have a shared library and i'd like to make some code conditional depending on who is using it

the code is in namespace foo. if i could access the namespace that required the code, that would be one method

another is to check for the general existence of a library in globals

cool stuff https://twitter.com/zetawargame/status/746070136256331776

@brian_mingus: ah you’re talking about detecting namespaces not projects it seems? it’s still not clear to me

Is it possible to use the CLJS compiler to analyse a namespace without fully compiling it? Specifically, I’m interested in introspecting information about vars in a namespace.

@cfleming: yes, cljs.analyzer.api/analyze-file

@dnolen: Awesome, thanks. Should that pretty much just require the classpath to be set correctly?

that’s right

That’s perfect, thanks.

@cfleming: we don’t store a ton of information beyond what Clojure does would be interested to hear if something is missing for tooling that we could put behind a flag

Ok, thanks - I’ll let you know. This is for generating stubs that can be indexed for libs that generate a lot of vars dynamically.

So I pretty much just need name, docstring and arglists to generate an empty function.

ok that’s all there
