quine-relay is an esoteric programming project that produces a single program which, when run, outputs the same program in another programming language; and that next-language version, when run, outputs itself in yet another language—and so on—cycling through many languages until returning to the original. It is effectively a “relay” of quines across dozens (or hundreds) of languages. The repository contains implementations, translation scaffolding, and carefully crafted code for each hand-rolled segment so the program maintains correctness across languages. Achieving this requires delicate handling of language-specific quoting, escaping, and code-gen tricks, making it a showcase of language theory, compiler insight, and meta-programming prowess. It is largely a playful, academic exercise exploring the limits of language interoperability and quine construction rather than a utility tool.
Features
- Single source program that cycles through multiple programming languages as quines
- Careful handling of escaping, quoting, and syntax peculiarities per language
- Implementation scaffolding to chain one language’s output to the next
- Demonstrates deep meta-programming and language interoperability
- Extensible design: possible to add or swap languages in the relay
- Artistic/academic intent: more a showcase of programming theory than a utility tool
