If you send me your app name off the list I can take a look at this.

Re: Separating Out .cljs Content

Hey Jonathan,

I just tried adding *base.js*. But another batch of dependency errors pop
up. It just seems that there's no straightforward way of keeping *my-code.js
* out of cljs' *main.js*.


   1. goog.require could not find: cljs.core
base.js:333


   1. Uncaught Error: goog.require could not find: cljs.core
base.js:337


   1. Uncaught ReferenceError: cljs is not defined
edgar.js:5


Hmm

Adopting plumbing/graph - But how?

2013-05-08 Thread Wolodja Wentland 
Hi all,

I am quite interested in using plumbing in one of my projects and have the
feeling that it is a perfect fit and indeed a better solution to something I
have written before. I can't, however, quite figure out the best way to
translate what I have into an implementation that uses graphs.

Consider a function such as:

(defn reducekv-fun
  [m]
  (let [m (reduce-kv
(fn [ret k v]
  (let [first-result (map inc v)
ret (assoc ret :first-result first-result)
ret (assoc ret :second-result (map #(- % 2) (get ret 
:first-result)))
ret (assoc-in ret [:third-result k] (map #(* 2 %) v))]
ret))
m
(get m :foo))]
   m))

where m would be something like {:foo {:first-set #{a b c} :second-set #{a b
c}}}. I want to keep keys present in m, but "update" some of them.

Which is something that I use in some places in my current codebase. It
essentially tries to model a graph and uses a map to move data from
one computation "node" to another. I don't really like this approach because it
is hard to change the actual implementation that is being called, there is no
verficiation that all necessary keys are present and it feels made up on
the spot. plumbing/graph looks as if it would fit perfectly.

I think that it should be pretty easy to translate this into an implementation
that uses plumbing's graphs, but I am running into problems with call like

   ret (assoc-in ret [:third-result k] (map #(* 2 %) v))

and am simply not sure how to handle them elegantly. What I would like to be
able to do in the end is:

* Replace the entire computation by a call to a single function (rather
  "hook" that returns a map that can be merged with the old map
* An easy way to compose that hook, essentially by adding multiple
  "subgraphs" together.

My basic idea is to have something like (but feel free to suggest something
completely different):

(defn reducekv-fun
  [m hook-function]
  (let [m (reduce-kv
(fn [ret k v] (hook-function ret k v))
m
(get m :foo))]
   m))

And the ability to define the computation as combination of multiple subgraphs
in the sense of (invalid code, but you get the idea):

(def compute1-graph
   { :first-result (fnk [v] (map inc v))
 :second-result (fnk [first-result] (map #(- % 2) first-result))})

(def compute2-graph
  { :third-result {k (fnk [v] (map #(* 2 %) v))}})

(def hook-function
  (fn [???] ...
(graph/???-compile (merge compute1-graph compute2-graph …
  compute5-graph

But I have problems with nested dynamic keys (such as the k in compute2-graph)
and am also not sure if this whole approach is a good idea. It looks as if
your library is *exactly* what I need, but I am stuck at making the first
step without breaking everything.

Thanks a lot!

Re: New Relic installation on Heroku

2013-05-08 Thread Jonathon McKitrick 
That's a good suggestion.  I made that change, and there definitely was a 
different because the heroku log said New Relic agent was already running 
because it had been specified in the JVM_OPTS.  So I removed it from there, 
restarted, but no change in the New Relic reports.  I even tried running 
without trampoline, but not success.

I'm still seeing the 'instances' chart updated, but nothing else.

Re: New Relic installation on Heroku

2013-05-08 Thread Leonardo Borges 
Are you using lein with "lein trampoline"?

If so, your app is running on a separate JVM, so you need to add this to
your project.clj:

  :jvm-opts ["-javaagent:newrelic/newrelic.jar"]

That was the bit missing for me. Hope this helps.

I should add... when the idle dyno spins up, I *do* see that in the 
instance chart on New Relic.  But none of the other stats show any activity.

New Relic installation on Heroku

2013-05-08 Thread Jonathon McKitrick 
I followed these directions to install New Relic on my Heroku app:

http://www.rafael-chacon.com/post/19069499949/new-relic-clojure-heroku-easy-steps-integration

I added my license key to the yml file, and restarted the app.  It's a 
simple app, with an import run from the CLI and an export as JSON web 
services.  I ran a few of both to trigger the New Relic agent.  At least I 
hoped so.

Though my New Relic account page located my app, it said no data was being 
received.  I thought this was an out-of-the-box setup.  Any ideas on what I 
can check to see what's going wrong?  I checked for log files, and found 
none created so far for New Relic.

Re: Parallel code execution in ClojureScript?

2013-05-08 Thread Paul deGrandis 
David is right, it can be done with workers.

I created a proof of concept in Shoreleave to do this dynamically.  The 
dynamic workers implemented IFn and supported IWatchable via the HTML5 
Messaging API.
https://gist.github.com/ohpauleez/2914039

About a month or so ago, I started creating a new proof of concept around 
parallel.js but haven't finished it yet 
(http://adambom.github.io/parallel.js/)
Parallel.js just wraps up the web workers stuff in a more convenient API.

Hope this helps,
Paul // ohpauleez

That's odd, it should definitely be possible to do - I've done it before.

Did you include the scripts something like this (from the dom example):




   goog.require('dom.test');
