What AI says about K Framework

K is a rewrite-based executable semantic framework for defining programming languages, type systems, and formal analysis tools, using configurations called cells and rules that label parts of the state as read-only, write-only, read-write, or unused to support concurrency. Computations are represented as extensions of the language’s abstract syntax and can be matched, moved, modified, or deleted within the rewriting environment, enabling control-intensive features such as abrupt termination, exceptions, or call/cc. The project provides tooling and resources including the K tool, Python interface, API/docs, tutorials, editor support, and community channels for learning, using, and contributing to K.
