Context Free Grammar Kit

Recursive Production Grammar (RPG) is a lightweight generative-literature engine designed for writers, researchers, and experimental coders who want maximum expressive power in a minimal footprint. RPG uses a clean, production-rule syntax to generate text recursively—ideal for poetry, stories, linguistics experiments, artificial languages, and procedural content.

Built for speed, clarity, and creative flexibility, RPG supports nested rules, controlled randomness, variable binding, reusable modules, and symbolic expansions. It’s easy enough for newcomers to use in minutes but deep enough for advanced users to construct full recursive literature systems.

RPG is part of a broader ecosystem of experimental text technologies developed by David Tolkacz, whose work explores recursive structure, self-modifying language, and the generative logic behind myth, prophecy, and symbolic literature (see works such as The Book of the Damned , The Devourer , and the extended Pantheon cycle).
