The try-haxe project is a browser-based IDE for testing Haxe code. It provides a quick and easy environment for playing with the Haxe language and compiles to JavaScript or Flash, instantly viewable in the browser. It also allows saving and sharing of programs with the auto-generated hyperlink hash-codes.

The official project is hosted at

Technical notes:

The try-haxe project is written in Haxe, with part of the application compiling to JavaScript for use on the client, and part of the application compiling to PHP as a backend service. The backend PHP service provides server-side compilation of programs as well as language auto-complete results.

Run your own instance:

You can run the try-haxe project on a server with Apache, PHP, and Haxe installed. Some commands may be distribution-specific (location of web server root, etc) -- the below works on Ubuntu.

Clone the repo and initialize the submodules:

git clone
cd try-haxe
git submodule init
git submodule update

You may need to update the location of the haxe compiler executable in the Compiler.hx source file, line 26. You can specify a full path to your haxe compiler, such as:

public static var haxePath = "/opt/haxe-3.1.3/haxe";

Build the try-haxe compiler and app:

haxe build.hxml

Link (or copy) this project directory to a location served by Apache (or other PHP-enabled web server):

sudo ln -s `pwd` /var/www/

The above creates a /var/www/try-haxe symlinked to your git repo.

Create the tmp directory (where web-based projects will be created and saved):

mkdir tmp
chmod a+rw tmp

Ensure Apache has mod_rewrite enabled:

sudo a2enmod rewrite

Edit the apache configuration file and add the /var/www/try-haxe location with AllowOverrides All directive (so it can use the .htaccess file):

sudo emacs /etc/apache2/sites-available/default

Add a <Directory> entry like so:

# Required by try-haxe
<Directory /var/www/try-haxe>
  Options FollowSymLinks
  AllowOverride All

Restart the apache server:

sudo /etc/init.d/apache2 restart

Navigate to your server (by name, ip address, or localhost) and enjoy try-haxe! http://localhost/try-haxe/
