Its official materials place it in the lineage of Smalltalk, Self, NewtonScript, Act1, Lisp, and Lua, with an emphasis on conceptual unification rather than surface syntax. ### Projektgeschichte The official timeline says Steve Dekorte began Io in March 2002 as a minimal prototype-based language, with early public releases and a programming guide appearing through the Yahoo Group community shortly afterward. In its first year, Io gained actors, coroutines, incremental garbage collection, weak links, networking, and a quickly expanding addon system. Io entered programming-language culture through its compact object model and message-tree semantics. The official timeline records a Lua Workshop talk and an ACM Dynamic Languages Symposium presentation in 2005, then source-history moves from email patches to a public DARCS repository, git hosting, and GitHub. The project continued to evolve through build-system and runtime changes, including a CMake transition in 2010, Eerie package-manager work under the IoLanguage organization from 2017, and a later WebAssembly/WASI direction with JavaScript bridging. The Homebrew package is therefore attached to a language with a long experimental runtime history, not just a frozen curiosity. ### Adoptionsgeschichte Io never became a mainstream application language, but it became memorable among programming-language enthusiasts because its tiny syntax exposes prototypes, messages, futures, actors, and code-as-data ideas directly. Its package-manager presence in Homebrew, MacPorts, and Nix reflects that role as a language runtime people install to explore or preserve a distinctive design. Adoption is best understood as educational and exploratory. Io is the kind of package that appears in language surveys, polyglot exercises, and prototype-object discussions because it shows a coherent alternative to class-based object systems and keyword-heavy syntax. ### Wie es verwendet wird Users run the `io` interpreter or build the runtime to experiment with message sends, prototype cloning, slots, blocks, addons, and concurrency constructs. The official guide and reference are central because the language's unusual semantics are easier to understand through examples than through command flags alone. ### Warum Paket-Nerds sich dafür interessieren Io matters to package nerds because it preserves a compact, radical language design in executable form. It also has the classic packaging shape of a niche language runtime: VM, interpreter, standard library, historical native addons, documentation, tags, branches, and compatibility questions across Unix-like systems. Its significance is disproportionate to install counts. A package manager carrying Io lets users reproduce examples from programming-language books and discussions, inspect a prototype-based VM, and compare the packaging demands of small language runtimes against larger ecosystems. ### Zeitleiste - 2002-03: Steve Dekorte begins work on Io. - 2002-04: Early public releases and a programming guide appear through the early community. - 2005-07: Io is presented at the Lua Workshop. - 2005-10: Io is presented at the ACM Dynamic Languages Symposium. - 2007-03: Source history moves from DARCS to git. - 2008-02: The Io repository appears on GitHub. - 2010-05: The build moves to CMake. - 2017-11: Eerie package-manager work is rewritten under the IoLanguage organization. - 2026: WASM/WASI work, stackless evaluation, resumable exceptions, and JavaScript bridging are recorded in the official timeline. ### Related projects - Self and Smalltalk are core influences on Io's object and message model. - NewtonScript, Act1, Lisp, and Lua are cited by the project as design influences. - Eerie is the related Io package manager recorded in the official timeline. ### 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:** io - **Version Scheme:** 0 - **Revision:** 1 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Andere Paketmanager-Einträge - Nix - io: normalized package name match | nixpkgs package indexes: pkgs/by-name/io/io/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - Io: normalized package name match | MacPorts ports tree: lang/Io/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 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. - [cmake](https://www.automicvault.com/de/pkg/brew/cmake/) - Build dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/de/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [gnu-apl](https://www.automicvault.com/de/pkg/brew/gnu-apl/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [gosu](https://www.automicvault.com/de/pkg/brew/gosu/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [groovy](https://www.automicvault.com/de/pkg/brew/groovy/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [janet](https://www.automicvault.com/de/pkg/brew/janet/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [julia](https://www.automicvault.com/de/pkg/brew/julia/) - Shares av.db curated category or tags: cli, dynamic-language, language-runtime, programming-language. - [lua](https://www.automicvault.com/de/pkg/brew/lua/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [luau](https://www.automicvault.com/de/pkg/brew/luau/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. - [nu](https://www.automicvault.com/de/pkg/brew/nu/) - Shares av.db curated category or tags: cli, language-runtime, programming-language, scripting. ## Combined YAML source View the package source record on GitHub.
