Hi, all
I'm trying to use clojurescript compiled to nodejs. I ran into a problem
with nodejs Buffer class, which doesn't have a namespace.
I tried different ways to refer Buffer:
(def b (Buffer. 1))
compiled to:
b = new mynamespace.Buffer(1)
this leads to an undefined error on runtime
If I u

I don't know if this works for this case, but the special namespace "js"

core.cache is a new Clojure contrib library providing the following

Great. Happy to help!

I've started working on a debugging infrastructure for ClojureScript based

here yet, but I've been surprised how much we get for free from the WRDP.
Most of the challenges will be around providing a good sexpr level

Thanks Tom. Using proxy like this could work. But i'm worried about
one thing.What happens if I have many instances? With proxy there's a
new class with each instance. Could I run out of permgen space?

I don't want to change the interface i'm exposing to the outer world.
May be that I'm thinking too javaish, but what I miss here is a
possibility to extend the base class. :)

Thanks. I don't know how this hashmap works, but at the first glance
there seems to be one problem: the two values don't get garbage
collected at the same time. I'll look more into it, thanks.

I think I understand namespace and then I don't!
I try to run this example

I have programs stored in c:\projects\klarity.clj
I have clojure stored in c:\clojure-1.2.1\clojure-1.21.

There are problems with weak hashmaps, but I wouldn't count that among
them

Thank you. It works now.
However, I think this is an issue of compiling clojurescript to
nodejs. *Buffer* is a nodejs specific function like *require* (a
nodejs function). So maybe we'd better use it like the way we use
require: (cljs.nodejs/require).
When compiled to nodejs, require is added to t
No, I'm sure to not use all the sequence, so I will follow your second
advice, but...
Cause of my non-perfect english I've not really understand the last

Who is the caller ?
You suggest something like this:

rd (lazy-reader fl)]

Yes, in the expression (conr (conr (conr '( 1 2 3) 4) 6) 7), all the
lazy-seqs implied by the conr calls must be forced immediately to yield

To do right, I should build a macro similar to let where I pass the

As part of a larger project, Topoged, I am developing a Hibernate
library that makes working with Hibernate from within Clojure much
easier IMHO. It uses the standard Hibernate configuration and
provides wrappers and whatnot to simplify the interaction. For

Easier to just use the pre-existing one: with-open.

Where by now:
(defn lazy-reader [fl]
(assert ...)
(lazy-seq
(cons (.read fl) (lazy-reader fl
The first one ?
This means that I haven't understand nothing, right?

Er, buffering of the I/O is probably preferable, but that would
probably work OK in many cases.
Thank you so much, just one last thing, why you use a char-array ?
If I want use a byte-array, and no map all the whole sequence ?
