Haxe Code Cookbook

Build Status

Sources for the Haxe Code Cookbook site, a community driven resource website for learning Haxe in practise.

The repository contains a static website generator, which converts markdown articles into a website. The project is being developed here on GitHub, feel free to contribute Haxe related code snippets and tutorials.


  • The actual articles are in assets/content/cookbook, organized per folder.
  • The html template files are in assets/content/.
  • The static files (css, js, images) files are in assets/includes/.
  • The Haxe source files of the generator are in src/.
  • The website-generated content will output in output/ (excluded from git).


Contributing changes

To contribute a change, you have to make a pull request. This can be done using the GitHub website or by fork/cloning the project.

Contributing using GitHub as online editor

This is the easiest way of doing small changes:

  • Navigate to an article on and press the edit button on any page: image
  • You are redirected to GitHub. Once you have an account and are logged in, you can make the change in the online editor.
  • Set the description / what you changed and press the Request change button: image
  • A pull request will be created. GitHub makes a fork for you automatically.
Contributing using a fork

This would also allow to test/see the changes before submitting which is also useful when you want to add new pages.

  • Make a fork (on GitHub) of the project.
  • Checkout your repo on your machine, create a new branch for the pull request.
  • Make the changes in that new branch.
  • Push the commits (they go to your fork).
  • On GitHub, you make a pull request from your fork's branch to the original repo.

Creating articles

Please add/edit the articles (markdown files) in the assets folder and do a pull request. The scope of the cookbook includes the core language, the standard library, and also any libraries maintained by the Haxe Foundation.


It would be nice if you keep the formatting of the code in the same style as used already:

  • Braces on same line.
  • Two-space indentation.
  • No type-hints for local variables and function return unless it's instructive.
  • Type-hints for fields.
  • Type-hints for function arguments unless it's very obvious.
  • Judicious use of extra line-breaks to avoid ugly automatic breaks (check the output).

Other remarks

  • The first heading is used in the navigation. Keep this title short.
  • The first paragraph is used as description. Describe what the content of the article is about.
  • Use > Author: [Name]( to mark yourself as author of the article. The other contributors are inferred from git commits.
  • Tag the article using [tags]: / "tag1,tag2" (no spaces). Try to use an existing tag.
  • Mention the author / sources at the bottom of the page.
  • If you want to include a code snippet use [tryhaxe](
  • If you want to include a YouTube video use [youtube](
  • If possible, link to related pages in the Haxe Manual / API documentation.
  • If you want to use images or other includes, create a folder called assets in the same directory as the article and link to that.

This would be a typical template to use. Use ```haxe for syntax highlighting:

[tags]: / "class,array,json,building-fields"

# Title of the page

Description and explanation of the code.

## Implementation
class Main {
  // Code here

## Usage

Description of how to use/test the code.

class Test {
  // Code here

Running a local copy

To run the project you can use Neko:

Call neko CodeCookBook.n to re-generate the output files.

Contributing to the generator

You need Haxe 3.4.2+ installed.

The static site generator source depends on hxtemplo and haxe-markdown.

Install the libraries using haxelib, run the following command in the root of the project:

haxelib install all

The CSS files are compressed using less. Install from npm:

npm install -g less
npm install -g less-plugin-clean-css
