Hi,
I would like to announce from-scala, an experimental Scala interop
library for Clojure.
Its main feature is the $-macro, a version of Clojure's
.-form. The $-macro uses Java reflection and a series of heuristics,
so that you will be able to write code like
($ ($ scala.collection.immutable

Quote-unquote the symbol: ~'create
Example:
`(defn create []) => (clojure
In judge try changing
(let [out async/chan] ...)
to
(let [out (async/chan)] ...)

That `lein midje` runs your expectations is just a side effect of
expectations' behavior to run its tests on JVM shutdown. Use
`(expectations/disable-run-on-shutdown)` to disable that feature.

I guess it's a lit
Hi,
you need to syntax-quote the list you return from your macro.
(defmacro some-record
[some-name]
`(defrecord ~some-name ['in 'out]))
Note the backtick `. You then also have to explicitly quote your record
field names (see 'in and 'out, try to remove the quotes to see why).
Also s
Using map and sets:
(defn days-number-maker
[all-days day-string]
(let [day-set (set day-string)]
(map (fn [day]
(if (day-set day)
1
0))
all-days)))
(defn days-to-numbers
"Change string like MTTH to (1 1 0 1 0 0 0)"
[day-string]

I hope I understood you correctly. You basically don't want to use
println if you want to print data in such a way that it can be read in
again. For that you need to use pr, prn or pr-str.
Example:
(println {:a "hi there"}) will print {:a hi there}
(prn {:a "hi there"}) will print {:a "hi the
java.util.TimerTask is an abstract class, which you cannot instantiate
directly. You can use proxy to create a subclass:
(proxy [java.util.TimerTask] []
(run [] ...))
Instead of (new java.lang.Boolean ...) use true or false directly.
There is syntactic sugar for new, just append a dot to the
Yes, you can tag your facts, and then only run the facts with a specific

I've changed the Leiningen installer, so that it uses wget instead of
curl. That should fix the problems you were having. I've only only
tested this on my Windows 7 VM, so please try it out.

Your macro is too complicated. You don't need to gensym a symbol in this
case. Instead just quote a symbol before unquoting it (note
Move membero to the beginning (just after fresh, like in succo), it runs

I have just uploaded some code I wrote earlier this year, where I
originally set out to generate some useful docstrings for Java classes and

It currently uses javadoc on all Java source files on the classpath and
