It lets semanticists write syntax, binding structure, and inference rules once, then generate LaTeX, Coq, HOL, Isabelle/HOL, Lem, OCaml, and related artifacts. ### プロジェクトの歴史 Ott was principally developed by Peter Sewell, Francesco Zappa Nardelli, and Scott Owens, with a wider contributor group. Its design was published at ICFP 2007 and then as a Journal of Functional Programming article in January 2010. The project arose from a specific pain point in programming-language research: full-scale semantic definitions are valuable but hard to keep consistent when they live only in informal mathematics or inside a single proof assistant. Ott's answer was a readable ASCII notation plus sanity checking and code generation into both publication and mechanized-proof formats. ### 採用の歴史 The Ott manual and repository document examples spanning untyped and simply typed lambda calculi, ML polymorphism, POPLmark F<:, TAPL systems, a Leroy-style module system, Lightweight Java, Java module-system work, and a substantial OCaml-light semantics. The JFP paper reports larger case studies including OCaml light with 310 rules and mechanized soundness results. Ott's adoption is strongest in programming-languages research, where the same source definition can support papers, collaborative editing, and proof assistant artifacts. The 2010 'Ott or Nott' workshop abstract is a useful adoption signal: it presents Ott as part of a working language-design process, not merely as a backend generator. ### 使われ方 A typical user writes an .ott source file describing object-language syntax and semantic judgments, then invokes ott with one or more -o outputs such as .tex, .v, .thy, HOL script, Lem, or OCaml files. The tool can also filter embedded terms in LaTeX, Coq, Isabelle/HOL, Lem, or OCaml source. The generated artifacts reduce drift between the published rules, the parser-level syntax, and the formal definitions used for mechanized reasoning. For package users, the command-line binary is the bridge between a research notation and several proof and documentation ecosystems. ### パッケージ好きにとっての重要性 Ott is a rare package that is both a compiler-like CLI and a research infrastructure artifact. Its package value comes from reproducibility: a language-definition source can be checked, regenerated, versioned, and consumed by multiple proof assistants and typesetting workflows. ### タイムライン - 2007: Ott was presented at ICFP as 'Effective Tool Support for the Working Semanticist'. - 2010: The Journal of Functional Programming article expanded the Ott design, motivation, and case studies. - 2010: 'Ott or Nott' discussed the experience of using Ott in programming-language design and mechanized-metatheory workflows. - 2024: The GitHub README stated that Ott remained in continuous use. ### Related projects - Ott sits alongside Coq, HOL, Isabelle/HOL, Lem, OCaml, LaTeX, POPLmark, TAPL-style calculi, Lightweight Java, and OCaml-light semantics work. ### ソース - - - - - ## セキュリティノート generalized runtime or code generation signal. - **Geiger リスク:** yellow / 中 - generalized runtime or code generation signal ## 他のパッケージマネージャ記録 - Debian apt - libcoq-ott - 0.34+ds-1+b4: normalized package name match | Debian stable package indexes: libcoq-ott from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Ott tool (Coq plugin) | https://github.com/ott-lang/ott - Debian apt - ott-tools - 0.34+ds-1+b4: normalized package name match | Debian stable package indexes: ott-tools from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Ott tool (executable) | https://github.com/ott-lang/ott - Nix - ott: normalized package name match | nixpkgs package indexes: pkgs/by-name/ot/ott/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - libcoq-ott - 0.33+ds-2build3: normalized package name match | Ubuntu 24.04 LTS package indexes: libcoq-ott from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Ott tool (Coq plugin) | https://github.com/ott-lang/ott - Ubuntu apt - ott-tools - 0.33+ds-2build3: normalized package name match | Ubuntu 24.04 LTS package indexes: ott-tools from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Ott tool (executable) | https://github.com/ott-lang/ott - MacPorts - ott: normalized package name match | MacPorts ports tree: devel/ott/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
