ClojureScript WebGL Figwheel Template

A ClojureScript WebGL Demo using Figwheel and Geom in order to interactively program WebGL!

Setup

Leiningen

First install leiningen, the popular clojure build system. On Ubuntu/Debian, run:

sudo apt install leiningen

On macOS with homebrew:

brew install leiningen

On Windows there's apparently an installer.

Lein should take care of the rest.

Coding

With that installed, in order to get an interactive development environment run:

lein figwheel

and open your browser at localhost:3449. This will auto compile and send all changes to the browser without the need to reload. After the compilation process is complete, you will get a Browser Connected REPL. An easy way to try it is:

(js/alert "Am I connected?")

and you should see an alert in the browser window.

Emacs

If you're running Emacs and CIDER, in order to get CLJS REPL-programming going you should first add the following line to your emacs init.el:

(setq cider-cljs-lein-repl
		"(do (use 'figwheel-sidecar.repl-api) (start-figwheel!) (cljs-repl))")

With that done you can now start figwheel from emacs with:

M-x cider-jack-in-clojurescript

And off you go!

Deploying

To clean all compiled files:

lein clean

To create a production build run:

lein do clean, cljsbuild once min

And open your browser in resources/public/index.html. You will not get code injection, nor a REPL.
