With the 1.2.0 release, there was an effort to get the most useful
parts of contrib -- IO and string handling, in particular -- into
Clojure proper, with the goal of making contrib unnecessary for
everyday programming.
Hopefully, contrib can go back to being what it was meant to be: an

Hi Phil,
I got it working with the our-classe-only plug-in.
I tested it on my brain damaged project and it kept only the class files
for which a name space exists in the source folder. The target is now
cleaned up of any external class dependencies.
Now, if others need this what do you suggest ?
Please, let me know if you're still having trouble using native-deps with
lein 1.3.0 in your projects.

Based on the docs, I was confused by that because I expected a hash
map (with keys a and b). When I ran it locally, I got:

Is there a way to specify default values for the fields of a

That is, if I have:

I want to be able to create a new Foo with:

This thread got me thinking that when a namespace is partially promoted to
Clojure proper, it might be good to provide a reduced version of the old
namespace, providing just the functionality that was not promoted as an

Anyway, I've sketched out the idea as a patch
A lunch club sounded like a great idea, so I'm organizing one for

How are you grabbing the sources? I'm also running under Windows, and
get the source from github via msysgit, which handles the crlf vs. cr
issue nicely.

Hi Timothy,
All Clojure code compiles to Java bytecode. You can do this on-the-fly at
runtime, and this is fast enough to be a reasonable option. Or, you can
AOT-compile (see http://clojure.org/compilation).
Clojure has a lot of granular abstraction under the hood. (Said another way:

Running 1.2.0 and I'm not seeing this. This only happen
I get sometimes ArrayIndexOutOfBounds in repl when creating a nested

{:a {:b "C"}}

Is it or would it be possible to add some basic text colouring to the

It would be nice to be able to make the prompt, e.g. "user=>" coloured

utilized.

While reading up on Clojure's to Java interfacing, I thought it might
be helpful to see how the clojure code appears to the JVM. Does
clojure compile the source directly to JVM bytecode? If not, is there
a way we can get the Java output for a given clojure source file?

Agree with Daniel Janus. There are some conflicts without any reason.
This should be cleaned up for 1.2.1 version.
More over when I build clojure-contrib-1.2.jar I get 4 failures on

All contributors and Rick do a great job but you should think

Hi,
so I finally got around to port my app to Clojure 1.2 and got confused
about the contrib shuffles.
There's clojure.java.io and clojure.contrib.io. The docs on the latter
says that most of the functions defined in there are deprecated, and
one should use clojure.java.io instead. But clojure.ja
