slime and utf-8
Hi, This seems to be an emacs problem. I'm trying to read a file with utf-8 text using (slurp foo.txt) in an emacs slime session. It chokes and says: error in process filter: Autoloading failed to define function debug Furthermore if I use utf-8 in the file name, I get: Coding system iso-latin-1-unix not suitable for 0076(:emacs-rex (swank:listener-eval \(slurp \\\/Users...filename...\\\)\) \user\ :repl-thread 3) I can live without utf-8 filenames, but it would be really useful to be able to read utf-8 data and println it etc. from the repl. Any suggestions? Thanks, Gregg -- You received this message because you are subscribed to the Google Groups Clojure group.

Since you use with-out-str it's not going to be lazily reading the file at the same time it tries to write it, either; everything in with-out-str will evaluate, loading the config and changing it and generating the new XML in a string, and then the string will be returned, and ds/spit called at that point, overwriting the file. -- Protege: What is this seething mass of parentheses?!

Tree vaadin?
I would like to translate a java example of tree vaadin to clojure. I have
to files in the same folder: planets.clj and core.clj. I am having problems
and I need help. What I am doing wrong?
*
*
*;; In the file planets.clj:*
(ns project.planets)
(let [planets (doto (Object.)
(Object. [Venus])
(Object. [Earth The Moon])
(Object. [Mars Phobos Deimos])
)]
*;; In the file core.clj:*
(load planets)
(defn -cjinit [][[] (ref {})])
(defn -init [this]
(let [tree (doto (com.vaadin.ui.Tree. The Planets and Major Moons)
(loop [i 0]
(str planet planets[i] 0)
(.addItem planet)
(if (= planets[i].length 1)
(.setChildrenAllowed planet false))
(loop [j 1]
(str moon planets[i][j])
(.addItem monn)
(.setParent moon planet)
(.setChildrenAllowed moon false))
(.expandItemsRecursively planet)
(recur (inc i]
(do (.addComponent main tree
*;; Java*
final Object[][] planets = new Object[][]{
new Object[]{Mercury},
new Object[]{Venus},
new Object[]{Earth, The Moon},
new Object[]{Mars, Phobos, Deimos},
new Object[]{Jupiter, Io, Europa, Ganymedes,
Callisto},
new Object[]{Saturn, Titan, Tethys, Dione,
Rhea, Iapetus},
new Object[]{Uranus, Miranda, Ariel, Umbriel,
Titania, Oberon},
new Object[]{Neptune, Triton, Proteus, Nereid,
Larissa}};
Tree tree = new Tree(The Planets and Major Moons);
for (int i=0; iplanets.length; i++) {
String planet = (String) (planets[i][0]);
tree.addItem(planet);
if (planets[i].length == 1) {
tree.setChildrenAllowed(planet, false);
} else {
for (int j=1; jplanets[i].length; j++) {
String moon = (String) planets[i][j];
tree.addItem(moon);
tree.setParent(moon, planet);
tree.setChildrenAllowed(moon, false);
}
tree.expandItemsRecursively(planet);
}
}
main.addComponent(tree);

Re: Tree vaadin?
Ooops - gmail malfunction
First problem, in Java:
new Object[]{Venus}
creates a new object array - containing the String Venus.
Your clojure code
Object. [Venus])
is trying to call the constructor of Object passing in a single argument
which is a Clojure Vector. This isn't going to work.
Look at
http://clojure.github.com/clojure/clojure.core-api.html#clojure.core/object-arrayinstead.

Clojure + PostgreSQL
Hi guys,
Anyone using Clojure and PostgreSQL? I'm trying to access PostgreSQL
using https://github.com/clojure/java.jdbc at the moment, but it seems to
have trouble with simple inserts:
(insert-record :temp {:parent 42})
#PSQLException org.postgresql.util.PSQLException: A result was returned
when none was expected.
..etc.. Perhaps I'm on the wrong track; what do you guys use or do?

dynamically create cmdspec for clojure.contrib.command-line

Exception: Unsupported binding form: something about foo I would expect this to be expanded to (with-command-line args desc [[foo a b]] (prn foo)) Which runs ok, directly in the repl: user (with-command-line args desc [[foo a b]] (prn foo)) 2 nil And (macroexpand (my-with-cl ...)) throws the same exception. How can I accomplish this, and why does my solution not work? Thanks for any help. Marc -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] emacs-clojure-vagrant: a sane development virtual environment
I've put together a simple development environment for those looking for a stable place to work on clojure code. The idea was dual purpose: a consistent environment for which to try out multiple code bases and something that is familiar to me when working on a foreign operating system. The included vagrant file will setup an Ubuntu 11.04 virtual machine with clojure and clojure-contrib 1.2, emacs 24 (with emacs-starter-kit 2 and all relevant clojure modes), tmux (similar to GNU screen), Leiningen and Jark. Special thanks to Phil Hagelberg for his help getting things setup. Please check out the github project hosted by the Seajure user group at https://github.com/Seajure/emacs-clojure-vagrant . Your forks and contributions are appreciated. Thanks, -justin -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Tree vaadin?
Maybe
(map #(.addItem tree (.toString (first %))) planets)
where #(.addItem tree (.toString (first %))) should be replaced with the
correct java interop for inserting into the tree, and the % becomes one and
one of the items in the planets vector (that is regarded as a sequence) the
argument.

struct sharing same key?
I would like to create an struct with the names of differents nationalities. When people are the same nationality I would don't need to repeat again the nationality. Is there any way t0 get that. For example, I would like to write something like that: (defstruct person :nationality :first :last) (def people (struct person english Jim Silvester Stephen Howards chinese Chiu Chiu)) -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Tree vaadin?
I've never used it, but you would use amap instead of map in this situation,
because it is a Java array.

You probably want something more like a map like this:
{:english [{:first Jim :last Silvester}
{:first Stephen :last Howards}]
:chinese [{:first Chiu :last Chiu}]}
