Here is some example code

This allows you to evaluate infix or rpn expressions. It also demonstrates
the use of eval to turn the expression into a clojure function which should
give more performance.
It is very simple though, so all the elements in the expressions hav
You could just write this yourself.
It's easier than it looks.
First start with an evaluator for rpn (reverse polish notation) expressions.
"x + sin(y)" in rpn would be "y sin x +".
First you split that string and make it into a list.
Then you can evaluate that with a few lines of code using a stac
Hi,
I was wondering if there are any good examples that show what
advantages clojure/lisp has over most other programming languages.
I mean a piece of code that couldn't be easily translated into e.g.
scala or java. A program that would take much longer to develop in
other languages due to the uniq
Thank you all for explaining this to me but I still don't understand
clojures behavior in this case,
Try running this code:
(def nums (drop 2 (range)))
(def primes (cons (first nums)
(lazy-seq (->>
(rest nums)
(remove
(fn [x]
Hi,
I tried experimenting with lazy sequences and wrote this program
(def nums (cons 2 (lazy-seq (map inc nums
(def primes (cons (first nums)
(lazy-seq (->>
(rest nums)
(remove
(fn [x]
(let [dividors (take-whil
I was wondering what's a good way to use OO concepts in clojure. Just
using multimethods and maps? Or maybe protocols?
Let's say I write a program that deals with many graphical elements
e.g. a game or a vector graphic editor.
I could represent each graphic/sprite/shape etc. as a map and define
mul
Hi,
I wrote this code to redirect a repl to a JFrame.
I used the JConsole class from Beanshell
(def console (bsh.util.JConsole.))
(def frame (doto (javax.swing.JFrame.) (.add console) (.setSize 500
500) (.setVisible true) ))
(binding [*out* (java.io.OutputStreamWriter. (.getOut console))]
