The processing package

[Tags:bsd3, library]

Processing is a visual design programming language. Processing.js is the sister project of Processing designed for the web. The Haskell processing package is a web animation library with Processing.js as backend.

What is this for?

With this library you are able to write scripts that, once executed in a browser, will execute interactive visual programs.

Where can I see a running example?

An example output can be reached at Also, take a look at The code of the latter is included in the source distribution (/examples/mill.hs).

How do I learn to use it?

The API reference of the library includes guidance and is complemented with code examples. Look also to the examples directory included in the source distribution. It contains some fully working examples.

The library provides different APIs (interfaces). Each one with a different philosophy.

The module Graphics.Web.Processing.Html helps you to create the HTML document where you will display the animation.
