Clojure is a Lisp that runs on the Java Virtual Machine (JVM).

IDE and infrastructure
- Lightmod – Lightmod is a tightly integrated tool for making full stack Clojure and ClojureScript web apps. It is fully self-contained – no need to install the JDK or any build tool. It hot reloads both client and server code automatically with zero setup.
Nightlight is an editor you run inside your Clojure projects. Instead of being a separate application like traditional editors and IDEs, it’s just a library that you add to your project. It spins up a web server and provides a completely browser-based interface to edit your code.
CIDER is the successor to nrepl.
- Cursive Clojure IDE – is an IDE built on IntelliJ
Getting started with Lighttable
Basic instructions. I use cmd for the shortcuts below, substitute ctrl on non-mac platforms.
- Install Leiningen http://leiningen.org/ you do not need to install clojure, lein will grab clojure for you.
- lein new playground from the command line to create a ‘playground’ project
- Open Light Table
- ctrl-space woto for “Toggle Workspace tree”
- Add the playground project folder you just created
- cmd-o core.clj to open the main clojure file for the project
- On an empty line type (+ 1 1) and hit cmd-enter
Things will grind away for a while as all the dependencies are downloaded and the JVM starts up. Get a cup of coffee or something. Eventually you’ll see a green 2 show up.
You can then type anything in the tutorial and hit cmd-enter to evaluate it or cmd-shift-enter to evaluate the entire file. Think of the file as a shell with an editable history instead of something you’d want to commit to source control.
Documentation is searchable via ctrl-shift-d or moving your cursor on top of a function name and hitting ctrl-d. Autocomplete is available on tab, you can jump to definition with cmd-. and back with cmd-,

- Elements of Clojure WIP as of Oct 2018.
The first chapter, Names, explains why names define the structure of our software, and how to judge whether a name is any good.
The second chapter, Idioms, provides specific, syntactic advice for writing Clojure which is clean and readable.
The third chapter, Indirection, looks at how code can made simpler and more robust through separation.
The final chapter, Composition, explores how the constituent pieces of our code can be combined into an effective whole.
