Clojure Programming

Clojure is a dynamic programming language for the JVM. Introduction[edit] People come to Clojure from a variety of backgrounds. The purpose of this book is to help everyone get the most out of the Clojure language. Feel free to post your own code, written in the Clojure language, here. Implementations[edit] There are a number of different implementations of the Clojure language: Clojure (the original Java-based implementation)ClojureScript (compiles to JavaScript)ClojureCLR (for Microsoft's .NET framework)clojure-py (Python-based)clojure-scheme (compiles to Scheme)ClojureC (compiles to C) See also Clojure-metal (thoughts/plans for Clojure on LLVM). FAQ[edit] Some answers to Frequently Asked Questions. Getting started[edit] The Getting started section covers obtaining and installing Clojure as well as basic setup of editors such as Emacs or Vim. Other "Getting Started" guides and documentation: Concepts[edit] Tutorials and Tips[edit] Learning Clojure gives an examination of Clojure's features.

Clojure History[edit] Rich Hickey is the creator of the Clojure programming language, with work experience on scheduling systems, broadcast automation, audio analysis and fingerprinting, database design, yield management, exit poll systems, and machine listening.[4] Before Clojure, he developed dotLisp, a similar project based on the .NET platform. Hickey spent about 2½ years working on Clojure before publicly releasing it, much of that time working exclusively on Clojure without external funding. At the end of this period Hickey sent an email announcing the language to some friends in the Common Lisp community. Philosophy[edit] Clojure's approach to concurrency is characterized by the concept of identities,[7] which represent a series of immutable states over time. Syntax[edit] Like most other Lisps, Clojure's syntax is built on S-expressions that are first parsed into data structures by a reader before being compiled.

Clojure | Home First hundred days of Clojure | byte bohemian In politics you have a one hundred days period of grace. In December I started to work with Clojure, so I guess it’s time to have a clojure look. In the last couple of years I encountered a couple of different languages. At scoyo it was ActionScript and Flex from Adobe. I had the honor to lead a team of great engineers, but with good people you don’t get close enough to the real stuff. When we started to work on our new product I said to my boss and my colleagues: In Java I know how a state of the art application has to look like, but I have no clue how to build a Clojure application. Leiningen (aka lein) – The build and dependency managmement tool for Clojure.Noir – A nice library to build websites/-services in Clojure.CongoMongo and mongoDB – The database driver and the database we use. My first days with Clojure When you are coming from a language like Java you are used to some things like:Structure everything – Static typing is your friend, so smack every data you have into a class.
