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..\\\")\") \"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.

Why not just nest the expressions: (ds/spit "./config/config-tst.xml" (with-out-str (lxml/emit (zip/root (zip/edit tags (zip/xml-zip (load-config)) value)) :pad true))) Now it will load the config (innermost ()), alter the value, then emit. 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?!

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.

It will set it if you use M-x clojure-jack-in. But if you're using raw slime you have to set it yourself. Unfortunately I don't foresee this being fixed upstream in Slime itself; they are still using CVS, so trying to convince them that iso-8895-1 is passé would probably not go over well. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Handling java streams..
Are there any libraries out there for making java stream handling nicer? My current project involves reading images from zipfiles, scaling them and then write them to a new zipfile. Any code I have seen involve mostly writing java in clojure and setting up buffers and such. Certainly I could do that, but it leaves me wondering if Java interop have to be such a pain. I would think one could patternize IO ops for most standard uses. Might just be my less than fresh Java knowledge acting up...

Sorry about that - known issue: http://dev.clojure.org/jira/browse/JDBC-10
It works fine on MySQL but breaks on PostgreSQL and SQL Server. I'll
get a fix in over the next couple of days (I'm away from home right

dynamically create cmdspec for clojure.contrib.command-line

[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. /Linus 2011/6/27 Antonio Recio > How I can translate this in clojure? > > for (int i=0; i String planet = (String) (planets[i][0]); > tree.addItem(planet); > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > -- You received this message because you are subscribed to the Google Groups "Clojure" group.

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. http://clojuredocs.org/clojure_core/clojure.core/amap Ambrose On Mon, Jun 27, 2011 at 1:08 PM, Linus Ericsson < oscarlinuserics...@gmail.com> wrote: > 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. > > /Linus > > > 2011/6/27 Antonio Recio > >> How I can translate this in clojure? >> >> for (int i=0; i> String planet = (String) (planets[i][0]); >> tree.addItem(planet); >> >> -- >> You received this message because you are subscribed to the Google >> Groups "Clojure" group. >> To post to this group, send email to clojure@googlegroups.com >> Note that posts from new members are moderated - please be patient with >> your first post. >> To unsubscribe from this group, send email to >> clojure+unsubscr...@googlegroups.com >> For more options, visit this group at >> http://groups.google.com/group/clojure?hl=en >> > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > -- You received this message because you are subscribed to the Google Groups "Clojure" group.

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