clojurescript Getting started with clojurescript
Remarks
ClojureScript is a version of Clojure that compiles to javascript code and runs in the browser.
While it is mostly the same as Clojure, there are a few differences (mainly, it lacks some api calls that invoke java functions that are not available in javascript)
Installation or Setup
Leiningen
Note: If you're going to use Leiningen, you first need to download and install JDK 6 or newer.
The easiest way to get started with Clojure is to download and install Leiningen, the de facto standard tool to manage Clojure projects.
Linux:
curl https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein > ~/bin/lein export PATH=$PATH:~/bin chmod 755 ~/bin/lein lein
OS X:
Follow Linux steps above or
Install with [Homebrew]:
brew install leiningen
Windows:
See https://github.com/technomancy/leiningen#installation.
Connecting to a REPL
Once you have lein installed, execute
lein repl
Start a new ClojureScript Project
lein new mies myproject
cd myproject
./scripts/build
Now open index.html in a Web Browser.
Press F12
Look at the Console, and observe the following:
Hello world!
