Ott
A tool for writing definitions of programming languages and calculi, generating LaTeX and formal proof assistant code from a concise ASCII notation.
What is Ott?
Ott is a tool for writing definitions of programming languages and calculi in a concise ASCII notation. It generates typeset LaTeX documentation and formal definitions for proof assistants like Coq, HOL, and Isabelle from a single source, helping to catch errors and ensure consistency. It supports functions for free variables, substitutions, and binding, and can be used as a filter to process embedded terms in source files.
Researchers and semanticists working on formal definitions of programming languages, type systems, or calculi, especially those who need to produce both informal papers and formal proofs.
Ott reduces duplication and errors by allowing a single definition to generate both human-readable documentation and machine-checkable formal code. Its concise notation and multi-format output streamline the workflow from informal to formal mathematics.
