Example-Based Live Programming for Everyone: Building Language-Agnostic Tools for Live Programming w
summary
Demonstrates a concrete system that implements language-agnostic ELP via LSP+GraalVM and a VS Code extension that runs examples, probes and per-example assertions on code running in Truffle languages. Shows Fibonacci examples named "ten" and "twenty" with expected outputs 55 and 6765, live probes that show intermediate variables, and assertions that flip true/false. Renders SVG return values inline and supports cross-language stepping so the debugger steps from R into JavaScript, all without per-language tool reimplementation.
