Any clues?
I don't know much about how Jython works, but from the stack trace it
seems like Clojure cannot load its source files from the classpath.
Are there other ways to add jars to the classpath in Jython?

It seems like this is a class loader issue... The guys working on
clojure-ant-tasks seems to have hit the same problem:

what i initially thought of, is an alternate technologie-stack. that's

Hello,
I am very new to Clojure, so please bear with me. I was reading
Programming Clojure and while reading about Macros, (specifically
Symbol Capture) I had the following question, could it be possible to
expand the macro into an anonymous function and evaluate that? For
example:

Hello everybody,
Today I just googled for macro-debugger and found the following ...

I have not completely explored it yet .. however, I was wondering if there
is something similar for clojure.. is it possible to develop one?
Thanks,
Sunil.

If you want that, you don't need macro.

))
But you would have to call it with:
(bench #(expr)) or (bench (fn [] expr))
You cannot do it directly because it would evaluate expr before the
call to bench.

Hi carlos ..
try the following it will work..
(- {:a 1} ((keyword a)))
clojure needs to know that it needs to coerce the keyword to a function ..
that is why your original thing won't work..

It's not specialized like your link, but I think you can use normal
debugging tools on macros:

The most recent Clojure refactoring conversation I've run across is
this, from 2008:

I'm working on a clojure web app that manipulates the serial
port. Well, uses it, anyway. The basic structure is to create a map
from web-visible names to devices accessible via the serial ports. The
problem is that Clojure and the serial port drivers don't seem to get
along very well.

Clojure is not javascript: scopes provided by functions aren't any
better than those created by let:
(let [start 1]
(let [start 2]
(println start))
(println start))
prints 2 1 as you'd expect. You *can* write a macro that will expand
this way, and most of the time it's not a problem

Hi,
Make sure none of your serial I/O calls are executing while compiling...
If you have anything like global defs that indirectly try to do an I/O
it will get executed as part of the AOT.
