Hi everyone!
I have hacked the Clojure core to add durability to refs. The syntax
to create these is (dref val key path), where key and path
are strings. Then you use them just
OK, it appears one more line of change allows clojure-contrib latest
as of today to build with clojure 1.3.0-master-SNAPSHOT. See inline

OK, one more quick hack I've found -- again, a hack, not a long term
solution. If you want to create a Leiningen project that uses the
latest clojure and contrib, read on. I couldn't figure out what to
use in project.clj unless I renamed this file first.
% mv
Cool!
I'm getting back to Clojure after an extended absence. Just today I
was pondering the design of a solution to a similar problem, though I
suspect our requirements diverge on several points. My tentative
conclusion was that it could be done entirely in Clojure and without
modifying existing

It's probably possible to do it completely in Clojure, but you have to
subclass Atom. There's no need for any transaction boundary; you just
have to make sure that compareAndSet does a durable swap.
My plan was to get durable refs done and then extend the other mutable
identities, including
On xbox, you can't alter running code in memory, which means JIT basically
doesn't work. So imagine you are running java code on JVM in interpreted mode,
it's too slow for any serious game.
This is a common issue in most game consoles.

(str if Xbox 360 has all you need to run Clojure), I was just
trying to emphasize that even if you could emit code you still had
other problems.

Not quite. Lua isn't a good example because it's a register based
runtime designed to be very small footprint. Also most of the games you

Civ 4 uses python but it targets PC too. Consoles have very different and

It was mentioned about six weeks ago that ClojureCLR was mostly 1.2
compatible with a few outstanding issues and a couple dozen failing
tests. What is the status now? Is there still an intention of an
official binary release with 1.2 level functionality, or has that
target been dropped?
Ah. I thought we were discussing prefs, or datoms (durable atoms), as
I would call them. Because datoms are only synchronous but not
coordinated, there's no transaction boundary. (More accurately, the
swap! is the transaction boundary, much like auto-commit.) dosync has
no effect on datoms.
This probably comes back to divergent requirements. Strict durability
is much too expensive for what I need to do. For me the more important
thing is that whatever authoritative data lives on disk is consistent
with the application transaction boundaries. This means that I need to
tag persistent

I'm not quite sure what you're asking. Clojure doesn't have byte literals, but
you can use the function 'byte' to coerce an int literal:
(map class [2 3 4]) = (java.lang.Integer java.lang.Integer java.lang.Integer)
(map class (map byte [2 3 4])) = (java.lang.Byte java.lang.Byte java.lang.Byte)
I just pulled the latest clojure and contrib and was able to build
them with one little glitch which I suspect is due to something I did

Building Clojure seems to install 1.3.0-SNAPSHOT but by default
Contrib seems to expect 1.3.0-master-SNAPSHOT ?
