I define a function foo in which it calls an auxiliary function bar,
which is not yet defined, and a compiler exception is raised claiming
unable to resolve symbol bar.
Is there a way that I can define the functions in any order I want,
without taking care of defining the auxiliary function first?
not yet.
But you can just declare the function, before implementing it:
(declare bar)
(defn foo [] (bar "hello"))
(defn bar [man] (println "hello" man))
Be aware that if you need to typehint bar, you'll also need to type
hint the bar declaration, so that the compilation of foo can use this

Parallel to proxy, clojure-clr adds a gen-delegate. Example code is

Try including [*print-dup* true] in the binding;
(defn write-nick-sets [file-name obj]]
(with-open [w (FileWriter. (File. file-name))]
(binding [*out* w *print-dup* true] (prn obj

Just a quick announcement for any musical Clojurians out there. I've
pushed midi-clj for simple MIDI communication, and osc-clj for
communicating with new school instruments via Open Sound Control.
Both were developed for project Overtone, but they might be useful for
other projects.

Hi all
In new issue of Russian FP journal (http://fprog.ru/) was published an
article about Clojure (http://fprog.ru/2010/issue4/alex-ott-clojure/ -
HTML, and http://fprog.ru/2010/issue4/ - different PDF sizes).
This is introduction-level article, that could be used as basis for
studying Clojure.

Hello Joshua,
I don't think there is an official standard in Clojure, at least not
yet. For a source of inspiration, you may be interested in this
thread, in case you haven't found it yourself yet:

Personally, I pre
Luckily there are already good Java libraries for doing all three of
these: jlayer, jorvis and jflac. We will probably integrate these in
with Overtone eventually, but for now we just use wav files for
samples.

Please forgive my mistake. I missed out a set of parentheses in there.
It should be something like this:

Yeah, I don’t really like the underscores either. But I have to work
with the set of currently allowed non-alphanumeric symbol characters
(*, +, !, -, _, and ?, according to clojure.org/reader).

people to bring in their input.

I think using a naming convention isn't a good idea, especially when
you have a rich macro system like Clojure. I'm actually going to be
talking about using a reference to handle things like this in my next
episode. For now, you can take a look at my definference macro here:

Could you explain more what you mean? For instance, how are macros
related to these questions? This just has to do with informal naming
conventions, in the same matter as *e or *print-dup*. Are you talking

macros that interpret symbo
Hmmm... maybe I misunderstood your point. Is the intent of your
naming conventions:
a. Something that is human readable but does not affect the execution
of code? Examples include placing I in front of interface names, and
A in front of abstract class names.

You can also do stuff in the middle of a let;

Here _ is just some arbitrary unused variable.

Yes. Instead of (ns foo.bar (:require [clojure.zip :as zip])) when
setting up the foo.bar namespace you can just use require in the user
