Quick reference

What is Haxe?

Haxe is an open source toolkit based on a modern, high level, strictly typed programming language, a cross-compiler, a complete cross-platform standard library and ways to access each platform’s native capabilities.

The Haxe compiler can output a number of source and binary files. As of Haxe 3.4.0-rc.1, the Haxe compiler can target JavaScript, Java, C#, C++, Python, PHP, Flash SWF, ActionScript 3, Lua, and Neko.

About this image

This image ships a minimal Haxe toolkit:

  • the haxe compiler with its standard library
  • the haxelib library manager
  • the neko virtual machine

How to use this image

The most straightforward way to use this image is to use a Haxe container as both the build and runtime environment. In your Dockerfile, writing something along the lines of the following will compile and run your project:

FROM haxe:3.4

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# install dependencies
COPY *.hxml /usr/src/app/
RUN yes | haxelib install all

# compile the project
COPY . /usr/src/app
RUN haxe build.hxml

# run the output when the container starts
CMD ["neko", "Main.n"]

Then, build and run the Docker image:

$ docker build -t my-haxe-app .
$ docker run -it --rm --name my-running-app my-haxe-app

Using the onbuild variants

There are onbuild variants that include multiple ONBUILD triggers to perform all of the steps in the above Dockerfile, except there is no CMD instruction for running the compilation output.

Rewriting the above Dockerfile with haxe:3.4-onbuild, we will get:

FROM haxe:3.4-onbuild

# run the output when the container starts
CMD ["neko", "Main.n"]

The onbuild variants assume the main compilation hxml file is named build.hxml. To use another hxml file, set the BUILD_HXML build argument during build:

$ docker build -t my-haxe-app --build-arg BUILD_HXML=compile.hxml .
