[ANN] Quil 1.0.0

Hello there dear Clojure friends, TL;DR - Rejoice, for Quil 1.0.0 has been released. https://github.com/quil/quil I'm sure you all know this, but programming doesn't just have to be for businesses to make money by optimising processes. Yeah, of course you knew that already. Silly me for repeating

Boolean

Hi, I am using Clojure for a month now. I like it a lot so far, but there are a couple of little details that make me very afraid. Foremost: (if (Boolean. false) "jesus" "christ") will return "jesus", not "christ". Googling this on the net, I found that this is a known phenomenon, and some ratio

Re: Nested refs & conflicting transactions

I did something similar at one point with a trading system. The map was something like {ticker {resting-orders [] pending-orders []}. The pending and resting orders were changing often, but we weren't changing what tickers we were trading very often. The entire map was a ref, and the resting and pe

Re: Boolean

Hi, You are not in the Clojure play ground when you use (Boolean. false). This expression creates a Java object, hence (if any-java-object ...) always evaluate the "true" branch in Clojure. In Clojure, anything not nil is true except false which is equivalent to the Java false value. (if false.

Well, I am an emotional programmer. And it just hurts when something potentially great like Clojure fucks up big time in the little details. I found the problem. It was caused by serializing a record value and later deserializing it: -

Re: Boolean

load-node and store-node are custom functions that rely on two other custom functions serialize and deserialize: (defn serialize "Serializes value, returns a byte array." [v] (let [buff (java.io.ByteArrayOutputStream. 1024)] (with-open [dos (java.io.ObjectOutputStream. buff)] (.w

Re: Boolean

Boolean/FALSE refers to the false value, not a boolean object. In Java you have primitive types and classes related to these types. false is the primitive value while (Boolean. false) is the object equivalent. The handling is much more efficient and simple with primitive types. Another reason to

Re: Boolean

Yes, but I am serializing the entire M-Node object in one go. Medium-term, I will write my own serialization for m-nodes anyway to get a more compact and well-defined format that does not depend on Java/Clojure versions. On Saturday, April 7, 2012 5:20:28 PM UTC+1, Meikel Brandmeyer (kotarak)

Help in porting Hiccup to ClojureScript

Hello ClojureScripters, I started to port the Hiccup library to ClojureScript. The goal is to have a port of Hiccup that has exactly the same api. This would make it possible to write views once (provided no platform specific code is used), and run them on the server with Clojure and on the client

Re: Help in porting Hiccup to ClojureScript

Hi Chris, yes I have seen crate. But I wanted something where I can share the same view code and use it on the client and the server and use the same api. I also think Hiccup's aproach to generate html strings at compile time is quite nice. That way the deconstruction of [:div#id.class] stuff can

Re: Help in porting Hiccup to ClojureScript

I think crate is about the closest that you're going to be able to get to hiccup in practice. ClojureScript macros are written in Clojure, and thus have to come from separate namespaces from the rest of the ClojureScript code. So, it is not possible to just port hiccup to ClojureScript on a v

Re: Help in porting Hiccup to ClojureScript

Hi Evan, I think Hiccup is a also a good starting point for this. In fact 99% of the port is already working. The last thing I struggle with is actually only cosmetics, like carrying over the meta data with the arglist and documentation. Why do you think it is impossible to have the same API in C
