Hi there!
Lets assume I have this map:
user=> (def person {:name "Father" :childs [{:name "Son" :age 10}]})
Testing:
user=> (-> person :childs first)
{:name "Son", :age 10}
Now lets filter the child map:
user=> (def only-name (fn [m] (select-keys m [:name])))
user=> (-> person :childs first

Thanks for the explanation!
So the solution is much simpler:
user=> (-> person :childs first (select-keys [:name]))
{:name "Son"}
Cool :-)

Hi,
thanks a lot. Your code looks much better than mine. But there is one
part that I don't understand:
(defn producer []
(if (dosync (if (not @consuming)
(alter data conj 1)))
(recur)))
How can I be sure that no more data is added to data after @consuming
was set to

Thanks for the link. It's a good start and it has prodded me to start
analyzing clojure core and contrib code - which I'm finding are
incredibly good examples of how to do 'stuff'.

Clojure data structures can be printed to a string, and the string can
be read back in as a data structure.

Sweet! I'd like to try it out. Wondering, though, might blogspot
have a feature of some sort to render the code in something more
palatable? I'd like to review it but it's a pain.

Hi, I gave it a try to find a solution to your problem. I ended up
using a single atom to hold the produced data and as means to detect
that consuming started (by swapping in a fn wrapping the produced
value). Don't know wether this fits your problem better than the one
already posted.

You need to prevent the modification of consuming by using ensure
rather than deref (@).

Thanks for the note about read-string and the example.
If I only had to consider Clojure I'd probably use that.
The Clojure structures are going to be persisted to/from a DB, and
then also read back (and maybe updated) later using other languages.
The tools I prefer to use for this are based on XM

I'm trying to create an HTTP server that is essentially a clojure REPL
with some integration into some classes on the server's classpath.
I've got something working, but I noticed some things that made me
realize I don't quite understand the scope of namespaces/imports in
clojure when eval'ing. I
New release of the Enclojure plugin for Netbeans has been released!
I have moved Enclojure to github and greatly simplified the build
process. See readme in the root directory of the repo for more
details.
http://github.com/EricThorsen/enclojure
You can download the release at:
http://github.com
any chance the enclojure plugin can be made available to download
from the NetBeans repo? It would mean much easier for netbeans
users to find and install it by simply bringing up the plugin menu
from within NetBeans.
Just a thought.

Oh - excellent point! I didn't think of that.
When it useful to be able to deref inside a dosync without ensuring?
Ensure seems like a more safe default of what I'd expect from a
transaction. So why not
hi,
is there perchance some way Clojure's REPL might be able to print out
more information in such situations? i don't know what precisely the
situations are. it is frustrating to not get more information to help
debug something. seems like it might be about anonymous fns or some
such?

There could be a verbose flag which would print the form in which the
error occurs. This shouldn't be default though as the forms can be
quite large.
