Hi Zak,
It seems very weird that my version of fac changes performance
characteristics on my machine and not yours (OS/hardware dependent?).
Can you tell your hardware configuration, esp. number of physical and
logical cores? I am planning next to leave out using pmap and just try
to run the thing
Hi,
I still didnt find good high coverage descriptions/tutorials about how
to write macros in Clojure. I read the stuff in Stuart Halloways book,
thats good, but just a small introduction.
I still have some technical questions, but the main issue seems to be
that I need to dive more deeply into t

Macro expansion is part of evaluation, whether at the REPL or elsewhere.
Syntax quote is not macro expansio

Hi Konrad,
many thanks. Thats stuff to ponder ;-)
(map (fn [s v] `(def ~s ~v)) '(a b c) '(1 2 3))
Thats impressive. I'm still, hm, puzzled. Nice example of something
that can only be done with syntax-quote, and outside of a macro. (Or

Yes.
Another question: could you add copy paste funcionality?

Hi,
I'm new to ClojureCLR and the DLR, so I'm trying to grasp the basic concepts
of it.
If I want to call Clojure code from C#, is it possible to compile the
Clojure code to a DLL and then reference it from my C# project, or am I
always supposed to load the script using methods?

The surface of the problem is reduced because of namespacing: two
different "fold" methods (with different semantics) from two protocols
won't clash. Plus if there are two extensions of the same protocol to
the same type, they should be rather equivalent since they satisfies
the same semantics.

Hi,
When 'destructure' is doing a map destructuring, 'pmap' is the
function to use. 'pmap' will do some kind of process to the given
bindings using these lines of code:

Whoops should have said:

ower-case-lay
eft-trim-lay
ight-trim-ray
Or something like that.

TryClojure is powered by jquery-console, which also powers TryHaskell.
jquery-console doesn't support paste functionality. While I imagine I
could somehow hook pasting (and might end up doing so), I have to
agree with Chris and the guys at TryRuby about pasting: copy/paste is
generally bad for lear

More of a Java question than a Clojure one, but it's in the context of
clojure, and I don't know a better place to ask, so forgive me...

This error indicates that your "java" executable is coming from the
JRE rather than the JDK. On windows, the JRE only includes the
"client" virtual machine.
If you have the JDK already installed on your computer, switch your
JAVA_HOME and PATH to use it instead, and try it again.

I'm surprised and I don't know why this is the case.

Indeed.
When I first started tryclojure, the idea wasn't really for it to be
much of a tutorial sort of thing as it was to just be a REPL-in-the-
browser sort of thing for general usage when you didn't have access to
an REPL. Eventually the tutorial got added, and I've been stuck
between orienting
I don't appear to have permission to go back and edit or add to the
ticket I created (#372), so here's a link to the [brief] IRC
discussion:
http://clojure-log.n01se.net/date/2010-05-29.html#21:48
I mailed a Contributor's Agreement late last week - not sure how that
process works, but I'd be happy
Update-in behaves oddly when getting an empty path. (update-in [] {1 2}
(constantly {2 3})) returns {nil {2 3} 1 2} not {2 3} as I'd expect. get-in
works well with empty pathes so I think this isn't a good behavior.

Heinz
