@maria Just read through your commit. Awesome! I think I’ll build a local copy of Closure to try it out.

mfikes: thank you :) they just released a new version of the Google Closure compiler (v20150609) including our changes, so you only need to adjust the version when building the ClojureScript compiler ;)

🙌

bumping Closure Compiler!

@ivar good chance EuroClojure video will be up sooner And it will be more relevant for Clojure(Script) programmers.

I'm also interested in seeing this talk @ivar @dnolen

@maria: Ignoring JSX for now, I’m experimenting with a gigantic :foreign-libs specifying :commonjs for React Native https://github.com/mfikes/rn-commonjs/blob/master/project.clj#L15

@mfikes: curious to see how that goes. re: JSX, looks like that’s now dropped for Babel

@dnolen: I didn't quite comprehend what they are doing. Is the JSX dialect going away or just the current transformer impl?

@mfikes: JSX is their custom transform tool, they’re just switching to a standard system and their transforms will be plugins far as I understand to Babel.

@dnolen: Ahh. OK. So if ClojureScript ends up supporting a transform plugin, the plugin for JSX is likely to be built in terms of Babel instead of the older implementation. I also wonder if it is just possible to pre-transform all of the React Native code manually prior to it even being seen by ClojureScript’s :commonjs (that’s at least what I might try in the interim)

@mfikes: that’s possible but too, but that just means more tools / more steps. I think better if you can just setup ClojureScript to do all the bits.

@dnolen: Yeah. I’m also wondering if the generation of the (gigantic) :foreign-libs can ever be automated, or if it would end up being packaged up into something perhaps in CLJSJS.

mfikes: it could probably be automated with some work

@dnolen: I’m cool with doing things manually in order to learn what the hurdles are

I need to allow the user to download (JSON) data as a file. Since I'm using Sente, I figured the easiest way would be to send the data to the client, and then use https://github.com/eligrey/FileSaver.js — anybody know of an easier way?

@jrychter: change the mime type?

@borkdude: of what? I have the data as a JavaScript string. Getting from there to a "download as" box isn't as obvious as I thought.

@jrychter: ah ok, you want to save a client side string (which happens to be json) to a file

Somebody could explain to me, what exactly happens when I do:

(deftype AType []
  Object
  (foo [_] "Hi!"))

In compiled code I see that it simply extends prototype of AType

Will it be compatible with advanced compilation?

How to call those methods? I will test this by myself, but maybe somebody knows any tricky parts of it?

@ul the only thing that isn’t compatible with advanced compilation - using strings for properties

Object methods are fully supported

so, (.foo atype-instance) will work fine?

if foo declared as described above

@ul yep

thanks!

@ul, that’s cool, didn’t know that

I have a special namespace question

where are the special namespaces js/ and Math/ handled?

I mean, clearly, they’re not real namespaces since they can’t be required.

shaunlebron: https://github.com/clojure/clojurescript/blob/master/src/main/clojure/cljs/compiler.cljc#L776

@juhoteperi: thanks, I saw that and I think it’s just for invocation

shaunlebron: What else would be needed?

Math/PI

just looking through the analyzer trying to see how it’s resolved

Maybe analyzer/analyze-symbol -> compiler/emit* :var

Who has recommendations for a decent calendar view through a cljs/react wrapper?

I'd like something that looks good on a phone. I've 95% rolled my own because cljs+closure makes it so easy, but I'm concerned that there is something I haven't thought of, like old IE

And obviously I want to drive the calendar view through EDN data.

I want it to function exactly like http://bookofmormonbroadway.com/tickets

thanks @juhoteperi, that’s what I was looking for

js is stripped at https://github.com/clojure/clojurescript/blob/f8af10da6429bab8e9838ac90a622b1858ffe983/src/main/clojure/cljs/compiler.cljc#L247

Math passes as an implicit namespace during analysis, passes through munge during emit* :var, where the / is replaced with a . here: https://github.com/clojure/clojurescript/blob/f8af10da6429bab8e9838ac90a622b1858ffe983/src/main/clojure/cljs/compiler.cljc#L78

@ghadi, if you’re using closure, you probably don’t have to worry about old IE

i'm not actually using closure for anything but generating vectors of weeks to layout using om

I hadn't really considered their widgets tbh

think I should?

@ghadi: looks like react supports down to IE8 http://facebook.github.io/react/docs/working-with-the-browser.html#browser-support-and-polyfills

I can’t speak on closure widgets though
