TesseractCore

TesseractCore defines the model, evaluation, and semantics (the Core) of a visual dataflow programming environment (Tesseract). The basic model in TesseractCore is a Graph<T>, which is a simple directed graph; Tesseract allows you to create, edit, and inspect such graphs with an idiomatic UI.

When specialized to Graph<Node>, graphs are assigned a semantics:

• Nodes have Symbols.
• Symbols are assigned Values in the Environment.
• Evaluating a Graph<Node> starting from a specific node evaluates all of the input Nodes, resolves its Symbol to a Value in the Environment, and applies the Value to the dependency Values (if any).
