Hi!
I'm using Clojure from Java via RT.loadResourceScript(...) and then
RT.var(...)
However this only works when I do
Var.pushThreadBindings(THREAD_BINDING)
and
Var.popThreadBindings()
around RT.var().invoke(), where THREAD_BINDING is a thread binding got
during script loading via (def ^:dyn
Well, I have checked different possibilites and the problem is not
about facade but lies in Clojure "eval" which is called on Clojure
structure done from transforming XML to Clojure structures. This eval
doesn't see context defined during loading time only if thread binding
is not restored. Any hel
Ok. I have solved this. I have replaced eval with eval-data
which is
(defmacro eval-data[ & body ]
(defonce this-current-context (get-thread-bindings) )
`(do (push-thread-bindings this-current-context)
(try (eval ~@body) (finally (pop-thread-bindings)

Ben,
It's a good idea, but it's going to bite you:
- what if the class in question has fields or package-private methods that are
touched by Java code?
- what if the class take ctor arguments?
- what if the ctor has side effects?

Firstly, sorry about this thread :-D
I wasn't trolling, honest, I just thought it was getting to the point
where the word was loosing its meaning.
There are many ways to express the notion of applying Clojure's
characteristics to one's code:

I don't think so. If lein.bat is on your path and is working, and if

Couple of clarifications. My main point is the maturity of the JVM, so when
comparing what is presented in the article (which isn't much), it can do
what is listed. That's not to say the converse isn't true, that PyPy's JIT
can do things the JVM can't do. Like I said, there are a lot of research

True...true, it supports it, but it's still a "2nd class citizen". For

Very true. But what it does do is abstract away the core elements of

without looking too much at your code, I might suggest you have look at my lazy

I'm interested in the differences between the default ClojureScript
