This Blockly can be used to build a block environment for a functional language.
Some features of this fork:
- Features custom connector shapes.
- Allows types to be polymorphic.
- Uses Hindley Milner type inference to determine the types of blocks.
- Changes the way local variables work. They can be instantiated by dragging them from the definining block.
- Allows custom using data types to be defined using algabraic data types, using sum and product blocks.
- Some support for first class functions.
A showcase of the this fork can be found at CodeWorld Blocks, which is a visual functional programming environment, which generates CodeWorld programs that are run in the browser. CodeWorld uses Haskell, which is a pure functional programming language, no side-effects allowed !.
This fork uses further changes from the following users:
- awmorph with his Blockly fork which he uses for math expressions, this fork is extends the work from Sorin's fork (below).
- slerner with his Blockly fork that supports better types and polymorphism.
Google's Blockly is a web-based, visual programming editor. Users can drag blocks together to build programs. All code is free and open source.
