You can't use Clojure to run Common Lisp programs on the JVM. Clojure
is it's own Lisp, and has nothing to do with Common Lisp. There are
some implementations of Common Lisp on the JVM, the most popular of
which I believe is ABCL.
I believe there are some experimental Ubuntu packages available, b

It should be fine.
I check to see if Clojure is already on the process's classpath. If it
isn't a Clojure process, I use the bundled copy of Clojure; if Clojure
is already loaded then I just use that

First, thank you Rich & Co for doing Clojure.
We've been using Clojure for a real-world project, and I thought I'd
share some observations.
The project does some large-scale (but not really huge) data
analysis. Example: ~10M records are processed and transformed,
various computations occur, and
All the parallel work will be done in Clojure, so I think I will go
with the refs and atom path. When the processing in Clojure is done
the data is passed as XML to another system so Java doesn't need to
change it anymore, so the immutability when it's done is not a
problem.
Thank you very much f

Hello,
First let me congratulate the clojure team on this wonderful

clojure? I was thinking specifically to Maxima - (the formal calculus
program)?
And finally another question: are there a

guessing that somehow i have t
In my experience, the NO_SOURCE_FILE shows up when I make a mistake at
the REPL/SLIME. When I have a precompiled .JAR, then I get a
reference to a specific file w/ a mistake in it.
That's why I was asking about what environment you used.

Sorry. I was just compiling everything and changing some code so it
broke. Where it actually came from is probably irrelevant, i have

also, this could be worth looking at: http://www.haskell.org/arrows/

Ok thanks for the answer :)

Since functions are going to run in parallel and a function may

I think it would be great if JLine is integrated in live-repl.
I have some questions:
* Why not use maven and clojure-maven-plugin?
* Is it OK if live-repl uses one version of Clojure and the attached
process uses another?
