Help sought on issue with AOT, hadoop, classloaders, and consistency of Clojure fn classes

First off, I apologize in advance for not having a reduced test case, and express my sincere gratitude in advance for any assistance. I've been tearing my hair out for a day or so and not making headway, and figured someone here might recognize some keywords and have a pointer in the right dir

gofmt like tool for Clojure?

Greetings, Is there a tool that reads .clj(s) source file and prints it in canonical fashion? (things like equal number of blank lines between forms, consistent placement of arguments vector in defn, etc.) I use Cursive IDE and it does nice indentation, but it is not enough. Ideally I would li

Re: Clojurescript to target JVM?

Hi Adam, This is really interesting, thanks - at some point soon I'm going to be doing some performance work on Cursive, a large part of which is going to be trying to stop namespaces being loaded before they're required. This will be very useful - I'll steal your patch to log namespace loading, f

Switched map for record and got slower

Another thing to note is if you were using these maps as keys to a hash-based associative structure, like a hash map, then you be aware that Clojure record do not cache their hash code like other Clojure persistent map impls do. I've had this eat up performance time in some scenarios before. Th

Re: Switched map for record and got slower

At the very least, all the places where you switched to method/property syntax now require runtime reflection. Try leaving those as they were, or switching to using the keyword as the function (which is somewhat more idiomatic). You could instead hint the appropriate object type in each functi

Switched map for record and got slower

Hello, I have a vector with ~20 elements that don't change. They are basically metadata information that are used on the application. Those 20 elements are maps, and I gathered them like: (defn units [] [unit1 unit2 ...]) I created a record and changed the gathering to: (defn units [] (ma

Re: Java Agent Based Modeling Systems and Clojure

Fred, This is an old thread, but did you end up using Repast, Mason, or another Java library with Clojure? I've been doing agent-based modeling in NetLogo and pure Clojure separately, but would be interested in exploring a more integrated approach. I have written a proof-of-concept NetLogo

Re: Resources don't work in uberjar

After perusing stackoverflow, it's evident to me that the "proper" way to access a file within a jar is to use getResourceAsStream (as was mentioned in the thread above, thank you), and I suppose clojure's io/input-stream does the trick as well. Thanks, all! -- You received this message bec

Re: Resources don't work in uberjar

Here's my goal: I have a thread that listens on a channel for tuples of [file-path, file-contents] and writes files to a zip file using clojure.java.io/copy. It's been really nice to be able to specify file-contents as anything clojure.java.io/copy can consume, such as a byte[] or a String, and

Re: Clojurescript to target JVM?

I'm currently using the fastload branch against alpha5, and it's pretty good. You have to be careful though with namespace declarations as you may end up loading more than you need to.

Re: Clojurescript to target JVM?

A lot of the slowness in Clojure comes down to how slow it is to load the main namespaces that are needed, especially clojure.core (see this post ). You should also look into the Clojure fastload branch, which apparently

OK something very strange is going on. I tried the let block, and it was the same in my project. So I created a new minimal project, lein new mies test-sound, and made a minimal test: https://github.com/retrogradeorbit/test-sound And here it works! Go back to my old project, and it doesn't.

No, that's not it. So I tried: (def audio-context (js/AudioContext.)) (.decodeAudioData audio-context (js/ArrayBuffer. 256) #(println "ok" %) #(println "error" %)) and it compiled to: ;var zv = new AudioContext; zv.Rd(new ArrayBuffer(256), function(a) { return fo.c(mh(["ok", a], 0)); }, funct

Re: alternatives to component (like) systems

You don't need a global reference that lives in your code to be able to interact with the scheduler at the REPL. I'd do it by breaking stuff into more bits - it looks convoluted for this simple example, but hopefully the idea makes sense: (defn make-scheduler [] (qs/initialize)) (defn start-sc

Re: Clojurescript :advanced compilation extern only partly working.

I just have a guess for you. AudioContext.decodeAudioData parameters are declared as ArrayBuffer, Function, Function but you are passing "data" which is a String not an ArrayBuffer. Maybe the type inference thinks you are calling a method that is not defined in the externs? Maybe it will work
