; A REPL-based, annotated Seesaw tutorial
; Please visit https://github.com/daveray/seesaw for more info
;
; This is a very basic intro to Seesaw, a Clojure UI toolkit. It covers
; Seesaw's basic features and philosophy, but only scratches the surface
; of what's available. It only assumes knowledge of Clojure. No Swing or
; Java experience is needed.
;
; This material was first presented in a talk at @CraftsmanGuild in
; Ann Arbor, MI.

djhworld / haskjure.clj
Created Sep 25, 2011
useful haskell functions that I can't seem to find in clojure
View haskjure.clj
(defn group [xs]
"splits its sequence argument into a list of lists of equal, adjacent elements."
(partition-by identity xs))
(defn zip [xs ys]
"makes a list of vector tuples, each tuple containing elements of both sequences occuring at the same position"
(map vector xs ys))
(defn lines [str]
"For a given string, split it into a vector using a newline terminator as a delimiter"
You can’t perform that action at this time.
