Visual functional programming with DRAKON-Erlang
summary
DRAKON visual diagrams map directly to Erlang functions via a plugin for DRAKON Editor that generates Erlang source code (it also emits C C# Java). Examples show hello world, branching, recursion, discriminant-based quadratic solver, state machines and a supervision-tree editor; the generator produces exports and OTP-style receive/timeout scaffolding. Historical claim: the Buran spacecraft control used DRAKON (1988) and a U.S. reimplementation took about 16 years to match it.
