@shaunlebron they have a blending filter (two of them are multiply and one is overlay).

Since cljs modules only work with optimizations turned on, and figwheel only works with them turned off, how do I go about developing a cljs code base with two entry points (two mains, if you will) ?

@magnars carefully 🙂

that might be so 🙂 but how do I make it work in the first place even?

don’t try to make modules work with figwheel

make the app work ‘normally’ with figwheel, then switch to the optimizations build and do it the hard way

so I can't rely on :main to do my requires any more then, I guess

there is no "normally", since there are two very different paths using some common elements

right. I don’t think that works in a normal :optimizations :advanced anyways?

:main works nicely with advanced

you might be able to do two figwheel builds

I think if you depend on a module, you should require it in any namespace that uses it

two figwheel builds sounds like an idea

@arohner thanks for the input, I'll give the two figwheel idea a shot in dev, and use modules in prod 🙂

let me know how it goes

@magnars @arohner since you are talking about it: shadow-build does modules for :none as well (shameless plug)

@thheller: interesting!

thheller interesting. What I really need is a way to reload code from an :optimizations :whitespace build

why?

my current project is injecting a CLJS file into an already-loaded page, over SSL

I mean why pay the overhead for :whitespace while developing?

:noneuses document.write

so you get the ‘cant use document.write on a completed page` error

it doesn't have to?

@arohner shadow-build also has a compact mode that emits a single file but :none

so no delay for closure

but is at odds with live reloading somewhat

I’ll look into compact

I would really love to make C-c C-k work

what is that? 🙂

(not using emacs)

eval the current file

that would be easy

I assume it is a load-file call under the hood?

in Clojure, yeah

@arohner: two figwheel builds works nicely, even in the same repl with (start-autobuild ...). I end up with 2x of the shared files as well, but that's fine for dev - and I'll just use modules in prod.

great

It seems goog.net.cookies doesn’t exist in cljs 1.8.51.

or in most recent cljs 1.9.x

I feel like I might be doing something wrong at this point because I know other libs depend on goog.net.cookies

@kingoftheknoll I believe it is goog.net.Cookies?

I’m thinking it’s because I’m trying it in the repl and not actually importing the lib into a namespace so it’s not sending it to the browser. Testing that now...

yeah you'll need the require

huh that’s interesting, I wouldn’t thought all of goog would be available globally and only pruned under optimization. Thanks!

you'd probably spend 10mins loading "all of goog", there is sooo much stuff in there 😛

Recommendations: Best "Learning Clojure" frontend framework

I was asked about om/om.next. I use om professionally, and I think it's great for large, long-term applications. But there are quite a few, somewhat complex concepts. So I'm wondering if others have found something more in the sweet spot for people learning the lang.

@potetm Reagent is pretty popular

I really loved Hoplon when I used it for a couple tiny school projects. Granted, I cam in with a bit of knowledge about Lisp and Hoplon's a little different to the other frameworks, but... I found it great for getting how good code-as-data is for the web. And who doesn't understand spreadsheets?

@dnolen Yeah that came to mind.

Hoplon also looks cool, but also a little more full stack conceptually

my impression is people starting out really enjoy Reagent + Figwheel

not too many things to think about and a lot of immediate feedback

Nice. I'll tell him about Hoplon. That was my impression as well @dnolen. Hadn't looked at it in some time though. Means a bit more coming from you 🙂

I might not be the best person to ask, there’s a lot of cool things going on these days and it’s hard to keep up 🙂

all I know is that the #reagent and #hoplon channels seem super friendly

@potetm: My intro to cljs was reagent with re-frame, it was a really easy way to start (this is about a year ago). Gives a bit of a framework for architecture around reagent that took away a lot of the initial questions I had.

Hey @shaun-mahood! Long time no talk!

(Met at last year's conj 🙂 )

nice I'll look at re-frame too

Ahh, I was trying to figure out why you seemed so familiar. 🙂

@potetm: rum is really good. very simple approach to choosing your react wrapper style (om, reagent, quiescent) with mixins: https://github.com/tonsky/rum

@shaunlebron Have you used both rum and reagent? I've used neither, but my impression is that rum might be simpler, but overall has more concepts to learn.

@potetm: I haven’t used reagent, but I started using rum about a month ago

maybe I don’t understand it all, but it seems straightforward

ha, I just realized I haven’t used any of the preset mixins

just a toy project without perf considerations: https://github.com/shaunlebron/t3tr0s-slides

i stick with atoms, and just call (rum/mount …)with add-watch

haha, yeah that was where I was like "this seems well thought out, but not as easy as: Here's your state, here's your views. GO"

ah yeah, well if you put it thaaat way 🙂

but it seems like rum let’s you start simple, which was the big appeal to reagent I think

right

and it has a pretty good avenue to adding features with a nice mixin model, I wrote some mixins for a canvas component, was just like hooking lifecycle events in Om or plain React. didn’t lose any power there

Cool. I'll pass the word on that one too.

👍

CLJs go loops ‘yield’, right? I have a long intensive function, and other stuff (webRTC) appears to be breaking because I’m not giving control back. If I converted to a go loop, would that solve the problem?

that really depends, you still have to park a go-loop so it doesn’t block the JS event loop

as long as the go-loop periodically comes up for air by reading from a channel with (<! …), yeah that’ll work

@arohner yes

the dispatch mechanisms hooks into the browser event loop, we defer to goog.async.nextTick

thanks. Does only parking yield, or does recur as well?

recur does not yield
