It emphasizes compilation by default, on-the-fly compilation from source, whole-program compilation, garbage collection, profiling, debugging, and an interactive shell. The Cisco-hosted project page separates current source, current release, open-source releases, and legacy releases, reflecting the project's long pre-GitHub history and later open-source maintenance. ### Adoption history Chez Scheme has long mattered to Scheme implementers because it is a serious optimizing compiler rather than only an interpreter. In package-manager catalogs it gives users a high-performance Scheme system through normal install flows. The input package metadata lists Homebrew, Debian/Ubuntu, Nix, Scoop, winget, and openSUSE packages. Homebrew reported 1,813 trailing-365-day installs at research time. ### How it is used The Homebrew formula installs `chez`, `petite`, and `scheme-script`, covering the full Chez Scheme system, Petite Chez Scheme, and script execution workflows. Users install it as a Scheme compiler/runtime, an interactive environment, or a dependency for Scheme research and language implementation work. ### Why package nerds care Chez Scheme is package-nerd-significant because it brings a historically important optimizing Scheme compiler into ordinary OS package managers, where it can be installed beside lighter interpreters. Its package also exposes the distinction between language runtimes that are research-grade compilers and ones that are small embeddable interpreters, a useful axis in Scheme packaging. ### Timeline - 2017: Chez Scheme 9.4.1 release notes documented supported platforms and changes after version 8.4. - 2026: Chez Scheme 10.4.1 released, with Homebrew tracking 10.4.1. ### Related projects - Petite Chez Scheme is distributed with Chez Scheme and appears as the `petite` executable in the package metadata. - The official project page connects Chez Scheme documentation with The Scheme Programming Language and the Chez Scheme User's Guide. ### Sources - - - - - ## Security Notes No matching local secret-handling manifest was found for chezscheme.
