Welcome to Project Forth Works

Forth would benefit greatly from an active community sharing sources and solutions. But our problem lies in the saying: If you've seen one Forth, you've seen one Forth. With this project we want to acknowledge our differences and start sharing despite the many different Forths dialects.

The core idea of ​​this project is to use a simple, generic version of Forth to spread ideas, algorithms, protocols, applications and hardware drivers. This generic version of Forth guarantees that it can be understood and used by (almost) everyone in the Forth community.

Contributing to the Project Forth Works is as easy as 1,2,3. All pages are written in Wiki Syntax format and editable once you register with the web site. You can use the playground to make your Wiki experiments.

You can contribute in different ways, your choice:

• Leave your comment in the discussion box below.
• Append another implementation to the existing one:

  • You can easily edit the page using the Edit button at the bottom of the page or the pencil icon to the right of the document.
  • Then just add your implementation between the <code> and </code> tags.
  • Save the page.
• Add a new idea:

  • Give it a name here in this document (e.g. in the category section below). Save this document.
  • Follow the red link to your new idea.
  • Create it using the pencil icon to the right of the new document.
  • Customize the pre-filled template to help you structure it.
  • Preview and edit, repeating until you are satisfied. You can save intermediate versions and continue editing later.
  • Save your new idea document. That's it.

To see what ideas have already been described, please see the wiki site map

• XORshift Random-generator, different random number implementations
• PiliPlop, an algorithm to move multiple processes, to reach its targets together
