It highlights isolated heaps for multiple VMs, lightweight VM-based threads, no external dependencies, Unicode support, hygienic macros, and an extensible module system. The project also ships command-line tools such as `chibi-scheme`, `chibi-doc`, `chibi-ffi`, and Snow-related commands, so the package is both an embeddable library and a usable Scheme command-line environment. ### Adoption history Chibi-Scheme's adoption is narrower than Chez Scheme or CHICKEN, but it appears in several Unix-style package sets because small embeddable interpreters are useful dependencies and testbeds. The input package metadata lists Alpine, Homebrew, Fedora, and Ubuntu packages. Homebrew reported 39,642 trailing-365-day installs at research time, a strong signal for a small language-runtime formula. ### How it is used The official README documents the normal source workflow as `make && make test`, producing a shared library and a sample `chibi-scheme` command-line REPL. Package users mainly care that the formula installs a tiny Scheme runtime, FFI tooling, and documentation helpers without a heavyweight dependency chain. ### Why package nerds care Chibi-Scheme is package-nerd-significant because it represents the opposite end of the Scheme packaging spectrum from big optimizing compilers: tiny, embeddable, no external dependencies, and suitable for C projects. It is also a useful R7RS-small package for testing scripts, build integrations, and extension-language experiments without installing a large runtime. ### Timeline - 2024: Chibi-Scheme 0.11 released. - 2026: Chibi-Scheme 0.12 released and tracked by Homebrew. ### Related projects - The README connects Chibi-Scheme to R7RS small and the `(scheme small)` library. - The installed Snow-related executables put it near the Scheme package/library tooling ecosystem as well as embedded C extension languages. ### Sources -
