  • Description: We introduce Teatrino, a toolchain that supports handling multiparty protocols with crash-stop failures and crash-handling behaviours. Teatrino accompanies the novel MPST theory in the related article, and enables users to generate fault-tolerant protocol-conforming Scala code from Scribble protocols. Local types are projected from the global protocol, enabling correctness-by-construction, and are expressed directly as Scala types via the Effpi concurrency library. Teatrino extends both Scribble and Effpi with support for crash-stop behaviour. The generated Scala code is executable and can be further integrated with existing systems. The accompanying theory in the related article guarantees deadlock-freedom and liveness properties for failure handling protocols and their implementation. This artifact includes examples, extended from both session type and distributed systems literature, featured in the related article.
