Hi Brian
Which books had you read? I found that Clojure Programming provides
many useful tips on how organize code, etc.

One thing that you might be missing is the expressive power of the sequence
handling functions (everything under sequences here:
http://clojure.org/cheatsheet ). I found it very useful to follow a few
other users in 4clojure [1] which allowed me to compare different styles in
their solutions
Congrats!

Hi there!
I'm wondering why ClojureScript seems to handle international characters
differently from Clojure.
Simple example in Clojure (= my preferred behaviour):
user= (str ø)
ø
The same example in ClojureScript:
ClojureScript:cljs.user #_= (str 'ø')
\xF8'
Can anyone explain to me why

I just cloned the current clojurescript repo, in a Windows 2008 server
machine, and follow the instructions:

But when I run .\script\repl.bat and tried (require
Hopefully someone else can answer why there is a difference in the output of
the str function. I suspect in ClojureScript's case, it is simply the default
behavior to use \x and two hex digits to display a character in a string with a
code point in the range 128 through 255, inherited from

There's nothing special going on, no empty identifiers. It's just a

Most of what could be accomplished by an internal define could be done with

Anyone voted for internal define lately?
On the one hand, internal define would be nice because it would help
alleviate the nested let problem and possibly be more intuitive for
newcomers.
On the other hand, sometimes
deja-vu :)

is imperative-looking syntactic sugar for monadic bind operators.

It's slightly different, but libraries such as Flow or Prismatic's Graph
can be used to achieve a similar effect.

Hello!
I've recently started playing with Clojure, and a couple of days ago I've
been pointed to Reducers in Clojure 1.5 after a discussion on #clojure at
Freenode.
I've read Rich's posts announcing the Reducers library, and he says that
there's a ***lack of reducible IO sources***. I'm
Damn, just noticed a small mistake in the macro: I use the original buffer,
not the duplicated one. Here's the correct version:
(defmacro buffer-reduce [b f val]
`(let [b# (.duplicate ~b)]
(loop [remaining# (.remaining b#)
result# ~val]
(if (zero? remaining#)
Bit of a late reaction, but there is nothing special about a tag with a
namespace prefixed. For example I have been using:
(zf/xml- zipper :ListRecords :record :metadata :oai_dc:dc :dc:language
zf/text)
which works perfectly well.

As a general-macro aside, you are multiply-evaluating the `f`
argument, by expanding it in-place inside the recursive clause. This
is almost certainly not what you want, and you could avoid it by
starting with (let [f# ~f] ...). Better still, ask why this is a macro
at all. This should really just
Another java newbie question, I expect. I tried using jvisualvm to profile
my clojure app. It's spending all its time in
jdbc.util.ReadAheadInputStream.fill(). The call tree points to
clojure-agent-send-off-pool-n. I'm not sure what this is telling me.

Thanks for the input. Didn't know that I was multiply-evaluating f.
The reason why I wrote a macro instead of a function is because 'get' and
'duplicate' are not declared in any common superclass of the different
buffers, so I was getting lots of reflection!
Are there alternatives to the macro

When I want to add print commands for debugging, I usually either do it
the way David Nolen described, i.e., binding _ to a printf statement, or I
use a little utility macro like this (picked up from stackoverflow):
(defmacro dbg[x] `(let

C is a C-language, and it seems a lot simpler than clojure to me. KR is
about 200 pages. I expect you mean C++, Java, etc. Not meaning to start a
language war, but my own experiences with C++ and Java have mostly
convinced me that the added complexity in those languages don't lead to

FWIW, when just wanting to print out debug values, I use a custom reader
tag similar to the above macro:
(let [x #log/spy (+ a b)]
(usage-of x))
That's nice! I haven't done anything with reader macros.
OK, just looked it up and realized that it's just how # works, and not a
special kind of macro.

So, the current version, after the suggestion by Alan Malloy, is the
following:

result# ~val]
(if (zero? remaining#)
