Quick Start Andare with Planck

andare-planck.md

Make a project.clj file that can manage the dep:

(defproject foo "0.1.0-SNAPSHOT"
  :dependencies [[andare "0.1.0"]])

Start Planck:

planck -Kc `lein classpath`

Then, use it:

cljs.user=> (require-macros '[cljs.core.async.macros :refer [go]])
nil
cljs.user=> (require '[cljs.core.async :refer [chan >! <!]])
nil
cljs.user=> (def c (chan))
#'cljs.user/c
cljs.user=> (go (prn (<! c)))
#object[cljs.core.async.impl.channels.ManyToManyChannel]
cljs.user=> (go (prn (>! c :a)))
#object[cljs.core.async.impl.channels.ManyToManyChannel]
true
:a

A few further notes:

1. The -K option will cause the compiled code to be cached, which starts to become noticable for a library the size of core.async. So, subsequent launches will be faster.
2. If you'd like the lein dep managment to be even faster as well see "Caching Classpath" here.
3. While things work fine with the shipping version of Planck, master has better REPL support for the asyncronous printing you are likely to encounter when playing with core.async. You can easily install master via brew: See the "Install Master" section here.
