The error shown in Ubuntu, when I try to execute the jar file, is:

The following is the file lists in clojure-clojure-source-1.3.0-

As you can see, there are no *.clj files in clojure-clojure-

So I think that it is natural that 'clojure/set.clj - source not

Do I misunderstand anything?

Clojure doesn't provide any mechanism to peek inside other threads. Dynamic
Var bindings create java.lang.ThreadLocal objects to store the temporary
bindings. A Java debugger or IDE *might* let you look at those.

To better understand what's going underneath, you're just calling the
addURL method of the classloader. But since you might be evaluating this at
the repl, there is an important point regarding the classloader. Everytime
clojure evaluates a form, it will use a new classloader on that form, and

This should be a function, not a macro. In fact it is just:
(defn multicmp [ xs] (first (remove zero? xs)))
But what you really wanted to begin with is a comparator function, so
more like:
(defn multicmp [ keys]
(fn [a b]
(or (first (remove zero? (map #(compare (% a) (% b))
The intent of making it a macro is that it allows short-circuit evaluation,
like Clojure's or/and. There is no reason to evaluate comparisons between
keys when an earlier comparison has already decided the ordering.
Hardwiring in the compare function and the order between %1 and %2 is an

Hi,everyone!
I'm a newbie here.When I'm reading Mark Volkmann's Tutorial,i make a
mistake by binding a non-dynamic var 'x' to new value.Then I def 'x'
with ^:dynamic again,but in this line (binding [x 9] (foo)), the
function 'foo' ignore the binding.Why?
Thanks for reply!!!
uer= (def x 0)
Hi,
just a guess: ^:dynmamic is a compile-time thing. foo was compiled without
it in place, so the compiler didn't consider it. Recompile foo after the
re-def with ^:dynamic and it should honor the setting.
Sincerely
Meikel
