## プロジェクトの歴史と使われ方
Otus Lisp, packaged as ol, is a small, cross-platform, purely functional Lisp dialect with Scheme influence. Its documentation describes it as implementing an extended subset of R7RS Scheme with built-in FFI, regular expressions, infix math notation, a REPL, an interpreter/compiler stack, and the olvm virtual machine.
### プロジェクトの歴史
The yuriy-chumak/ol repository was created on 2014-09-06. The project presents itself as both a language experiment and a practical embeddable runtime, emphasizing a tiny footprint, cross-platform support, and foreign-function access to C, Python, Lua, and operating-system APIs.
### 採用の歴史
Otus Lisp has niche adoption compared with major Scheme and Lisp implementations. Its presence in Homebrew and Alpine packaging, plus its GitHub topic footprint around R7RS, FFI, interpreter, compiler, and virtual-machine work, show a package aimed at language implementers, embedded scripting users, and Lisp collectors rather than a broad application ecosystem.
### 使われ方
Users run ol or olvm to experiment with the language, execute scripts, embed the runtime, or use the FFI as a compact bridge to native libraries. The package's appeal is strongest where a small Lisp-like runtime and direct foreign calls matter more than a large library ecosystem.
### パッケージ好きにとっての重要性
For package nerds, ol is interesting because it is not just another Scheme package: it combines a deliberately tiny runtime, R7RS-flavored semantics, and a virtual-machine/compiler design in a Homebrew-installable artifact. It is the kind of package that preserves an independent language implementation in mainstream package indexes.
### タイムライン
- 2014-09-06: The yuriy-chumak/ol repository was created on GitHub.
- 2026-07-01: GitHub repository metadata reported 278 stars, 14 forks, Scheme as the primary language, and active repository pushes in 2026.
### Related projects
- Related references include R7RS Scheme, SRFI libraries, other embeddable Lisp and Scheme runtimes, and the repository's own olvm virtual machine. The package metadata also connects it to Homebrew and Alpine Linux package ecosystems.
