Text is a experimental visual language under development. Code and docs will appear here at some point, but all I have for now is this video of a proof of concept.
It’s basically Haskell but with syntax based on proximity in 2D space, rather than adjacency. Type compatible things connect automatically, made possible though Haskell’s strong types and currying. I implemented the interface in C, using clutter, and ended up implementing a lot of Haskell’s type system. Whenever something changes it compiles the graph into Haskell code, which gets piped to ghci. The different colours are the different types. Stripes are curried function parameters. Lots more to do, but I think this could be a really useful system for live performance.
