(#({:a %}) :b)
|
| |
The expression (#({:a %}) :b) should evaluate to {:a :b}, but raises an exception instead: Wrong number of args (0) passed to: PersistentArrayMap This is a pretty irritating bug and makes the #% form essentially unusable for me, because I cannot rely on it but have to always second guess if its use is safe in the current context or not.... more »

the recent RC1 release it's time to properly announce it here.
What can you do with Neocons?

lazy-cat infinite realization on empty seq
|
| |
Hi,
This has probably been asked a million times but I couldn't find
anything.
Why the following triggers infinite realization of the infinite lazy
seq and how I can work around it and make it stop when f1 returns an
empty seq,
(defn f1 [] (println "hello") [])
(defn f2 [] (lazy-cat (f1) (f2)))... more »

Using Clojure internal libraries in another project
|
| |
Hello all,
We're interested in using some of Clojure's internal libraries (in particular, it's STM implementation), in the runtime for another programming language. We were wondering if anyone had attempted this before, and if there are any things to keep in mind along the way.
Cheers,
Edward... more »

clojure.java.jdbc byte[] result type question
|
| |
Hi.
I've got a clojure.java.jdbc result coming back as a byte[]. Its from
a GROUP_CONCAT on an int(10) field.
In the mysql client the result is: '1,2,4,6,7,19,24,32,54,152'.
I am unsure how to extract this result properly in clojure… (println
(seq (somevar))) gives me an unexpected result: (49 44 50 44 52 44 54... more »

Learning clojure: debugging?
|
| |
I'm early in the process of learning clojure, and am hoping that the
community has suggestions for a frustration I've run into.
Preamble: as a learning exercise, I'm porting a hex-grid geometry library I
originally wrote in Haskell. Here's the relevant bit:
(ns hex.core)
(def origin {:x 0 :y 0 :z 0})... more »
