Practical Clojure

You will find any confirmed erratum below, so you can check if your concern has already been addressed. On page 18: There is a space after "! " in the typed input which is not in the returned value. On page 32: In the function "square-or-multiply" the second alternative implementation is wrongly indented. On page 33: The output of the prompt is not consistent "#'user/sq" versus "'#user/multiply" (ie. the order of "'" and "#"). On page 44: The application of arg-switch with a custom function seems wrongly indented (ie. the indentation of "(/ a (* b b)))" and "2 3)".

On page 46: There is an "-" before rangechecker in the text (which also appears in the index). "#´user/times-pi" => "#'user/times-pi". On page 53-? In all of chapter 4 the symbol "->" is used to denote the result returned from an evaluation, but the symbol is only used in this chapter as far as I can tell.

(OCI) last updated on 6/2/13 Contents Introduction The goal of this article is to provide a fairly comprehensive introduction to the Clojure programming language. Please send feedback on errors and ways to improve explanations to mark@ociweb.com, or fork the repository and send a pull-request. You said X, but the correct thing to say is Y. Updates to this article that indicate the "last updated" date and provide a dated list of changes will be provided at Also see my article on software transactional memory and the Clojure implementation of it at Code examples in this article often show the return value of a function call or its output in a line comment (begins with a semicolon) followed by "->" and the result. (+ 1 2) ; showing return value -> 3 (println "Hello") ; return value is nil, showing output -> Hello Functional Programming Functional programming is a style of programming that emphasizes "first-class" functions that are "pure".

Until completed, duplicate content may be seen. For detailed coverage of Clojure, consult the language and API reference at clojure.org. Clojure (read as closure), is a powerful, lisp-1 programming language designed by Rich Hickey and designed to run on the Java Virtual Machine.

Getting Started with Emacs - Clojure Documentation

As a new entrant into clojure and to some extent to Emacs, I struggled a bit to install and get them working and had to refer many resources in web. To help people like me starting out in "Emacs + Clojure + Swank + Leiningen", I am putting together detailed set of instructions building on top of what is in the page above: DETAILED INSTRUCTIONS - for EMACS + CLOJURE : (emphasis on Windows - will apply to other OSs also): Emacs set up:

A Brief Beginner’s Guide To Clojure. By John Gabriele, last-modified: 2013-08 (using Clojure 1.5.1, Leiningen 2.2.0, and OpenJDK 7) The purpose of this brief guide is to provide an overview of the Clojure ecosystem while also helping new users quickly get up and running.

A Brief Beginner’s Guide To Clojure

This guide concerns the original, Java-based Clojure implementation. There are others. It’s not a Clojure language tutorial; there are already a number of good ones available (linked to later). This guide is not comprehensive; it’s just a handful of nicely-organized notes that I thought would be most useful to new Clojure users. The author (hi!) It’s intended that the chapters of this guide be read in order. Overview - Seesaw API documentation. A Swing wrapper/DSL for Clojure.
