hi,
are there any plans to something along the lines of e.g. having
autodef be something that can be turned on per-file via some
expression in the file itself?
thanks.

Just FYI this came up a while ago:

I'm very interested in this also - if it has been progressed in any
way.

That is a good point. I'm actually not sure why I used type there.
It's probably a bug. Thanks for pointing it out.

It was a minor thing actually, I didn't like having to quote "user"
code, and AFAIK, it's not possible to add a quasiquote as part of a
macro. i.e. in my code, there is a function (_js) that does the heavy
lifting, and the macro (js). I couldn't write:
(defmacro js [forms]

The pesky thing about that particular error is that there IS no more
context; it fingers no specific line of code, function definition, or
whatever as culprit.

It seems to be an infrequently-encountered bug in load-file. If you copy and

I'm not an expert on asynchronicity with clojure, but I'll benefit from the
fact i'll be the first to answer :-)
But please take this with a grain of salt.
As I see agents, in their generality, they are "a generic way to handle a
state asynchronously (commands from multiple non organized sources -
Hi All,
This is a question about whether I can use agents or some other Clojure
concurrency feature to manage a multithreaded process elegantly and
extensibly. The following is a thought I had for how to do it, but I would
appreciate additional suggestions.

Check out clojure.contrib.duck-streams/reader and clojure.contrib.duck-
streams/writer (http://richhickey.github.com/clojure-contrib/duck-

They'll give you a java.io.BufferedReader or a java.io.PrintWriter
which is usually what you want with a file. If you have some other
use,
Can you give some more context?

Here is another question on when you would use a multi-method. I want the
mv function to accept a java.io.File or a String for either of the two
parameters and here are the options I came up with:

(defmethod mv [String String] [from to]

I assume you mean doing this at the REPL or OS shell. I don't know how
to do it for non-loaded libs, aside from manually walking the classpath,
but (all-ns) might be what you want for loaded namespaces.
