Re: [ClojureScript] How can I get core.async to work in Cljs in Cljs

[mikefikes18]

Yes. Look at the documentation for the cljs.js load function.

Re: [ClojureScript] How can I get core.async to work in Cljs in Cljs

[Zubair Quraishi]

Hi Mike,
 I didn't necessarily mean that core.async is slow in my last comment, but more 
that macro evaluation can be slow. The clojurescript macro file in question is 
here:

https://github.com/zubairq/BlocklyBuilder/blob/master/src/webapp/framework/client/macros.cljs

It seems to take at least 5 seconds to compile in bootstrapped clojurescript. 
So are you saying that I can precompile and cache this file so that the browser 
never has to compile it?
thanks
Zubair

Hey Zubair, 

For a library of the size of `core.async`, I’d recommend making use of 
bootstrapped ClojureScript’s ability to cache the results of compilation. You 
can at least eliminate 95% of the start up time (with Andare). Here is an 
example (where the -K option to Planck enables caching):

$ time planck -Kc andare-0.2.0.jar -e"(require 'cljs.core.async)" 
-e"(require-macros 'cljs.core.async.macros)" -e"(cljs.core.async.macros/go)"
#object[cljs.core.async.impl.channels.ManyToManyChannel]

real0m27.401s
user0m36.093s
sys 0m0.940s

$ time planck -Kc andare-0.2.0.jar -e"(require 'cljs.core.async)" 
-e"(require-macros 'cljs.core.async.macros)" -e"(cljs.core.async.macros/go)"
#object[cljs.core.async.impl.channels.ManyToManyChannel]

real0m1.505s
user0m2.658s
sys 0m0.357s

Re: [ClojureScript] How can I get core.async to work in Cljs in Cljs

[mikefikes18]

Hi Zubair,

There are no plans on my part for pushing for that.

(My opinion: It is a relatively heavy set of code changes, useful only to a 
small portion of the community. If bootstrap becomes important enough where 
Cognitect would like to consider revising core.async for self-hosted use, at 
least Andare exists as a working example of how it can be done.)

Hi Zubair,

Basic `core.async` constructs now work in self-hosted ClojureScript in the fork 
I've been messing with. See

[ClojureScript] How can I get core.async to work in Cljs in Cljs

[Zubair Quraishi]

I am trying to get core.async (go macros to work in cljs in cljs but they seem 
to do nothing. I try fully qualifying them as well with 
(cljs.core.async.macros/go but it makes no difference. Anyone else have 
core.async working with cljs in cljs?

Hi Zubair,

It definitely doesn't work as-is. I've been working through revisions to see if 
I can get it to load into Planck (and Elbow, a Replumb-based REPL for node). 
It's not complete, but my changes are in the self-host branch here if you are 
curious:

Nobody at Cognitect is working on this. It's unlikely to be very high
priority either as the payoff for most users is non-existent.

I don't have specific plans to release a stable version. If things lead to
