haXe is an open source and multiplatform programming language. To learn more and get the latest info on why using haXe and the platforms it targets, check out the haXe Introduciton.

Installation

To get started with haXe, you'll need to download a few extra add-ons.

Download haXe

Visit haXe's download page [001], and download one of the automatic installers for your platform. For this example, we'll be installing haXe for OSX.

While installing, the installer may ask you to install Neko. Neko is a language / Virtual Machine platform that Run the installer. Even if you never use Neko and haXe together, it may come in handy in the future and it's a small footprint to you're system [002].

When the installer is complete, confirm that the installation of haXe was successful by opening your console and executing the command haXe:

haxe

If installed correctly, the console should print out haXe info:
