Has anyone done any work sharing OpenGL contexts in Clojure? I was
wondering the best way to create a GLCanvas if I want all of them to
share the same context.
Right now it seems calling (.getContext (new GLCanvas)) returns nil,
which may be a JOGL thing, but I was hoping to create one canvas wit
I want to map a dictionary and do different things depending on the
key. I was planning on using an if-clause, but I'm not sure how to
compare symbols to strings.
Something like
(map (fn [k v] (if (== k "hello") ... ...) {:hello 1 :goodbye 2})
How would I normally compare symbols and strings?
What's the function to call java code on multiple java components? If
I have a sequence of Java swing components and I want to go through
and set the same properties for each one, I would use a for loop in
Java. If I were using immutable structs in clojure, I'd just a map
and just change the keys
What's the best way to keep track of what kind of value something is?
For example, if I have a hash of floats and I want to go through each
one and see if a given key-value, which happens to be a float, if it's
a distance or a frequency? Or if something is a struct or a specific
struct? I'm somew
In the relatively short time of using clojure, I'm a little frustrated
with it's limited information the stack provides. I'm assuming
there's something I just don't know or am not doing. Many times when
I do something wrong, I have to read through the stack which sometimes
just says there's an er
Is this the common way to do it?
(def sister (assoc brother :name "Cindy"))
Reading up more on structs, it seems they have base keys that can't be
dissoc. Is that the main difference then between it and a hash?

use a hash if structs can hold new values anyway? When should I use
one over the other?

This may be really basic. So much so that it's hard to find on the
internet, but is there something like a copy constructor in clojure,
where I can copy everything in a structure except one or two keys?
Maybe something like struct-map, but fills in the other variables not
supplied by another data
I have a function that I use for adding a JPanel to a ui atom. When I
call swap! that ui atom is sent to that function I call with the swap!
on and is dereferenced inside the function so I don't need to call @ui
on it. However, I want to add listeners to my JPanel that can affect
that atom, but I
I'd like to separate my ui Swing/JOGL from the content, so my code is
relatively unaware of the UI around it. For example, I create a

the user does some interaction like a mouse click or drag, the UI
creates a new context. My OO

If am creating accessors to access structures, how should they be
named?
(defstruct employer :employee)
(defstruct employee :employer)
(def employee-name (accessor employee :employer))
(def employer-name (accessor employer :employee))
In a situation where one struct is pointing to the other, is t

I don't know if adding to the library path is causing the new error,
or if this is just the next error in getting the script to run. Am I
setting the library path incorrectly?

I downloaded the new jogl 2.0 libs and can't get jogl to be recognized
in my classpath. It's stuck on the import.
(import '(javax.media.opengl.awt GLCanvas))
In my shell I have clojure aliased to 'java -jar clojure-1.0.0.jar'
I have my CLASSPATH as

Has anyone had problems with netbeans starting with the enclojure
alpha? I restarted my session and it died. Now when I try to run
netbeans, it throws a classpath exception. Can I remove this plugin
or am I missing something in my install?

I have implemented the half-edge data structure several times now for
mesh representation. Basically there are three main data structures
(vertex, edge, face). I'll explain them a bit, but I think this is a
more functional programming/Clojure question than actual geometry.
A vertex is a corner o
Object-oriented design has been frequently sourced as becoming
