Intro to Clojure lightningtalk
This document provides an introduction to Clojure, a Lisp dialect that runs on the JVM and JavaScript. It highlights that Clojure is functional, immutable, and was designed by programmers for programmers. The document outlines Clojure's syntax including keywords, symbols, strings, integers and using lists for everything. It also mentions Clojure's data structures like vectors, maps and sets and libraries for web development, databases, games, drawing and more. Finally, it advertises an upcoming ClojureBridge workshop.
Intro to Clojure lightningtalk
- 1. Intro to Clojure Forprogrammers Lightning Talk
- 2. • a dialectof LISP • Runs on JVM, CLI, Javascript • Functional • Immutable • Designed by Programmers for Programmers Rich Hickey created in 2007 What is it?
- 3. Syntax • Keyword ...:a :b • Symbol ... println • String ... "Hi Mom" • Integer ... 42
- 4. List All TheThings • Everything is a list with ( ) • (function-name parameter parameter) • (println "hello world") • (+ 1 2)
- 5. Data Structures • Vector(collection) [1 2 3] • Map (hash) {:a 1 :b 2 :c 3} • Set (unique collection) #{1 2 3 }
- 6. ( ) aren’tthat bad!
- 7. nREPL • Sort oflike IRB/Pry for ruby, but better • Evaluate code from editor Light Table, Emacs, Sublime and others
- 8. Cool Libraries • OM- Facebook react library • compojure - websites • korma - object relation mapper for databases • play-clj - game library • quil - a wrapper around Processing for drawing/animation • overtone - playing musical sounds • synaptic - neural networks • cascalog - data processing • datomic - query engine built on top of database storage
- 9. Austin ClojureBridge • March13, 14 • Rackspace North Campus • Friday night install fest 6pm-8pm • Saturday workshop 9am-3:30pm, 4:00 after party • Saturday night after party at Pinballz Arcade • Free and food/beverages provided by sponsors • Rackspace, DRW, Pragmatic Programmers, O’Reilly, Threatgrid/Cisco
- 10. Resources • Clojure fromthe Ground Up • Clojure for the Brave and True • Clojure Programming • Joy of Clojure Search for these videos: • Rich Hickey • Simple Made Easy • Stuart Halloway • Intro to Clojure from NDC • Simplicity Ain't Easy
Editor's Notes
- #9 OM is a wrapper around the Facebook React library Compojure is somewhat like ruby Rack Korma is a ORM, where you can create entities and have easy access to data, awesome play-cli is a wrapper around libGDX, desktop, mobile apps quil - creates graphics and animations synaptic - neural networks used for machine learning casalog - query language for hadoop datomic - a database, which separates storage from queries in a unique way
