Rockstar 2.0: Building an Esoteric Language Interpreter in .NET
summary
A joke language becomes a real implementation: an initial Rockstar interpreter in JavaScript gains a language‑agnostic test suite, attracts 42,000 PicoF users and MIT use, and someone solves Advent of Code in Rockstar; the project is then rewritten in C# to target .NET 8 native AOT and WebAssembly, using a PEG library (Pegasus) for parsing, JavaScript worker + JSExport interop for safe browser runs, poetic literals and “ninja strings,” and it runs as native binaries and in the browser.
