Donatello Flow-based Programming Editor

A pure Java implementation of Flow-based Programming (FBP) and a GUI editor.

Data-flow programming is aesthetically pleasing, greatly reduces the chance of syntax error, and empowering for people that are not fluent in the archaic syntax of text-only languages.

Features

• Nodes are not directed or forced to run via triggers. There is little danger of large networks overflowing the stack. They could be run in parallel.
• Folding: Collapse a subgraph down to a single Node with Fold and reverse with Unfold
• Convenient built-in nodes for basic math and reporting.
• Unit tests for everything! If it can be tested, we shall!
• The editor has written in Java Swing. The main executable class is com.marginallyclever.donatello.Donatello.
• While running the Swing editor you can also access Swing-only nodes like LoadImage and PrintImage. PrintImage results will appear in the background of the node editor panel.
• A ~/Donatello/ folder contains the application log file.
• A ~/Donatello/extensions/ folder contains 3rd party plugins. Add new Nodes or write your own.
