It inherits OBJ features such as mixfix syntax, subtyping, module composition, parameterized modules, views, and module expressions, while adding rewriting logic, hidden algebra, and combinations of those paradigms. The open interpreter source is maintained in Common Lisp and can be built with Allegro CL, SBCL, or CLISP. The GitHub repository was created in 2017, while the README for version 1.6.0 is dated 2020-01-20 and the repository carries later 1.6.x tags. ### Adoptionsgeschichte CafeOBJ's adoption is specialized: it lives in the formal specification and verification community rather than mainstream application development. Packaging in Homebrew and Ubuntu makes it easier for researchers, students, and toolchain curators to install the interpreter without manually building a Lisp system. ### Wie es verwendet wird Users write formal specifications, load them into the CafeOBJ processor, reduce terms, inspect modules, and construct proof scores. The official introductory material walks beginners from describing specifications to verification using simple natural-number examples. ### Warum Paket-Nerds sich dafür interessieren CafeOBJ matters to package-history nerds because it is one of the long-tail formal-methods languages that package managers preserve alongside mainstream compilers. Its Homebrew formula keeps a Common Lisp-based research language installable on modern developer machines. ### Zeitleiste - 2017: Public CafeOBJ interpreter repository created on GitHub. - 2020: README marks CafeOBJ interpreter version 1.6.0 dated 2020-01-20. - 2020s: 1.6.x tags continue the interpreter line. - Present: Homebrew and Ubuntu package the interpreter for easier installation. ### Related projects - OBJ is the direct predecessor named by the official CafeOBJ README. - CafeOBJ sits near other algebraic specification and rewriting-logic tools, but its official documentation frames its own lineage through OBJ, rewriting logic, hidden algebra, and proof scores. ### Quellen - - - - - ## Sicherheitshinweise generalized runtime or code generation signal. - **Geiger-Risiko:** yellow / mittel - generalized runtime or code generation signal ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cafeobj - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Andere Paketmanager-Einträge - Ubuntu apt - cafeobj - 1.6.0-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: cafeobj from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | new generation algebraic specification and programming language | http://cafeobj.org/ - Ubuntu apt - cafeobj-mode - 1.6.0-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: cafeobj-mode from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Emacs major mode for editing CafeOBJ source code | http://cafeobj.org/ ## Verwandte Links - [Secret-risk packages](https://www.automicvault.com/de/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/de/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/de/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/de/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [zstd](https://www.automicvault.com/de/pkg/brew/zstd/) - Runtime dependency declared by Homebrew. - [sbcl](https://www.automicvault.com/de/pkg/brew/sbcl/) - Build dependency declared by Homebrew. - [ats2-postiats](https://www.automicvault.com/de/pkg/brew/ats2-postiats/) - Shares av.db curated category or tags: cli, formal-methods, language-runtime, programming-language. - [agda](https://www.automicvault.com/de/pkg/brew/agda/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [alda](https://www.automicvault.com/de/pkg/brew/alda/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [algol68g](https://www.automicvault.com/de/pkg/brew/algol68g/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [ballerina](https://www.automicvault.com/de/pkg/brew/ballerina/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [befunge93](https://www.automicvault.com/de/pkg/brew/befunge93/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [brainfuck](https://www.automicvault.com/de/pkg/brew/brainfuck/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [c3c](https://www.automicvault.com/de/pkg/brew/c3c/) - Shares av.db curated category or tags: cli, language-runtime, programming-language. - [julia](https://www.automicvault.com/de/pkg/brew/julia/) - Local package facts share a topical domain.
