One question that has been coming up at the back of my mind for the
past several weeks has been how difficult would it be to create a
collaborative multi-user online virtual world application in a
semi-functional programming language, such as Clojure.
More specifically, last August, I came across

Hi,
How can one contribute to the development of Clojure on CLR?
I was trying the following - (.ToString DateTime/Now) and was getting

I'm going to do what I did last year:
1. Learn a functional language (Clojure this year; OCaml last
year).
2. Try to do the the problem in said new language.
3. Give up and switch to Python. :)

Not totally clear what you are trying to accomplish, but would something
like the following work?
(defn get-value [start-value]
(loop [updateable start-value line (.readline reader)]
(if (or (empty? line) (> line-num max-num))

Hi all,
I'm using Clojure for web apps inside Tomcat. If I don't compile
my .clj files ahead of time, I will eventually get one of these
OutOfMemory errors, after a number of redeployments. Is there
something I can do about this? Is this a bug somewhere, in my code,
or in Clojure, or in Tomcat
Hi clojurians,
I was happily clojure-coding whent I tried to catch a exception in a

After looking for the fact that the IllegalArgumentException wasn't
catch, I added a catch RuntimeException to my catch list ... and that
worked of course.
Here is the simplified cas

Why isn't the following satisfactory for your needs? get-value takes a value
returns a new value based on it. do-something can 'do something' to/with
this new value.
(defn get-value [start-value]
(loop [updateable start-value line (.readline reader)]
(if (or (empty? line) (> line-num max-num
You could do something like;
(let [updated-val (loop [updateable start-value line (.readline reader)]
(if (or (empty? line) (> line-num max-num))
(+ updateable (somefunc))
(recur (.readLine reader)]
(do-something with updated-val))
Rgds, Adrian.

Re-read your example - that should have been;
(let [updated-val (loop [updateable 0 line (.readline reader)]
(if (or (empty? line) (> line-num max-num))
(+ updateable (somefunc))
(recur (.readLine reader)]
(do-something-with updated-val))
I.e initialising updateable to 0.

The Clojure run time throws IllegalArgumentException in a lot of
different places. It does also throw RuntimeException
in several places. It traps exceptions generically (catch (Exception e),
catch (Throwable t) ) and may have thrown a RuntimeException back
to upper layers instead of the original\
Here's a fuller example of similar techniques extracted from a working
program. It reads a file of lines and applies some transformations and
accumulates a vector of records which it finally returns;
(defn some-fn

(let

Yes to all of the above.
Github will always be the most current version. I'm rolling changes
out to contrib on a less frequent basis.

And CA definitely required.

Are you familiar with Mono and the recent attempts from the Mono
developers to make the VM more functional programming language
friendly,
Adrian and David are suggesting how to work functionally, which is best when
appropriate. Berlin, if you really need state modified over time, Clojure
does this differently from most languages. Values never change, only
references to values and only in controlled ways. Maybe what you want is a

I have a Clojure applications with different files, different
namespaces and I have imports of classes within those files/
namespaces.
lets say
(import java.io File)
(import thepackage SomeClass)
Is it possible to lazy load the imports of the class. For example, if
I start my app, I will get a
I haven't hit the permgen issue, but it sounds like I have a similar

your .clj files? I typically connect via Slime and use slime-load-

I'm looking for feedback on a date utility library I'm writing. It's
