Clojure development environment guides

Coaches can help you set up development tools on your laptop if you wish to continue discovering Clojure after the ClojureBridge London event.

Common tools required

Tool	Is it installed?	Install guide
Java 8 or above	java -version	Java install
Leiningen	lein version	Leiningen install
Git	git --version	https://git-scm.com/

Clojure is a hosted language and runs on top of Java or JavaScript (and other platforms). The Java Runtime Environment (JRE is needed to run Clojure.

Leiningen is a build tool for running Clojure code, creating and managing projects.

Git can be used to version your Clojure code, so you can go back to earlier versions if you make a mistake.

Clojure editor choices

Install guides are provided for all these editors.

Atom & ProtoREPL install guide

Atom.io is flexible and simple to use editor. The ProtoREPL plugin adds support for Clojure and ClojureScript.

Using Vim style editing

We don't directly support Vim (although we will do our best to help). You can use Vim with the fireplace plugin to work with your Clojure REPL.

Both Spacemacs and Atom/Proton have great support for Vim style editing and so are a viable alternative.

If you wish to use Vim, take a look at some of these articles for help.

• Clojure and Vim: An overview - its very possible
• Clojure docs: Clojure with Vim and fireplace.vim
