Sorry but it's a bit off-topic, any one tried running compojure in REPL in clojure eclipse plug-in?? I failed with that while it works in Netbeans plug-in.Any help?

Using Ref
Hi :
I would like to simulate a simple database with the STM of clojure.
The rules are
1. There can be many rooms, and each room has its own attirbute
2. One room contains many people, and each person has its own
attribute
3. rooms can be created, and deleted, and people can be added into or
removed from room.
So I made a globle variable *rooms*,
where *rooms* is a reference of a sequence of references of rooms,
where room is a hashmap, with an attribute of reference of a sequence
of references of people.
Just like this,
(def *rooms* (ref {"room_1" (ref {:players (ref [(ref
player)])} ) } ) )
Ouch, it has 4 refs @@
I think it's hard to control, but why did I make that many ref?
If there is fewer refs, the functions that alter might need to see
outer ref to do an alter.
Any one got an idea to make the code easier ?? Thanks

Memory Problem
Hi : I would like to know why ( from http://stackoverflow.com/questions/749911/how-can-i-leak-memory-in-clojure ) (drop 90 (vec (range 100))) would cause memory problem in clojure and how to fix it?

STM with deeper structure
Hi :
Say, I have a (def *a (ref {:b [{:c 5}]})) .
I want to add 1 to the :c inside, how would I write?
(Note: the value 5 is in (:b 0 :c), while 0 is the array index)
(dosync (alter *a __ )) ; please help me fill the blank.
Someone mention I can use the zipper library or the walker library,
but after I checked I still have no idea how to make it.
Thanks.

Not sure if it's a bug or not
Hi : In my web project the namespace is jinrou-clojure.army, and the file is at jinrou-clojure/army.clj, most the the classes are compiled to jinrou_clojure directory, but some files with name army$reify__3155.class are compiled into jinrou-clojure/army directory ( note: it's a - , not a _ like most of the files, which I think it should be _ like most of the files ) I am using leiningen with leiningen-war to compile the file though. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Slow static file handing with lein ring server
I don't know why, but it seems to have a one second delay getting each static file even in local host testing. :dependencies [[org.clojure/clojure "1.2.1"] [org.clojure/clojure-contrib "1.2.0"] [compojure "0.6.4"] [ring-serve "0.1.0"] [enlive "1.0.0"] [clojureql "1.0.0"] [mysql/mysql-connector-java "5.1.6"]] :dev-dependencies [[lein-ring "0.4.5"]] (defroutes main-routes (route/files "/") (route/not-found "Page not found")) And I even tried route/resources, it's still slow, any idea to make those file cached or any Jetty configuration is needed? Note : I used firefox httpwatch to test, it seems with Http 1.1, after the page is retrieved, it simultaneously retrieve 5 image files each time, but it takes one second only to return the image is not outdated (note : the image is not transfered, just the header). -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Slow static file handing with lein ring server
Hi : Thanks for the reply. The entire page costs about 5 seconds loading about 40 pictures with each picture about 3K. And when I put the pictures under some static web server (Nginx), the picture loading time is down to 0.4 seconds, while the main page (compojure/ring/enlive) costs still a long 1 second in local host testing. I am not sure it's because of jetty or compojure or ring, but if it's picture it shouldn't be enlive. I would think to move the project to maybe Lift, for the clojure solution seems a bit slow.

comp inside macro

I would like to create a macro as follows.

but I would like to evaluate the composition of one predefined function and
the other from the input argument.
And I got some errors, why?
