history
Project history and usage
Chibi-Scheme is a small Scheme implementation intended for embedding as a C extension and scripting language, while still providing a substantial R7RS-small-oriented default environment.
Project history
The official README describes Chibi-Scheme as a very small library for use as an extension and scripting language in C programs. 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.
