Miniature, embeddable Scheme

Stak Scheme

The miniature, embeddable R7RS Scheme implementation in Rust

Stak Scheme aims to be:

• An embeddable Scheme interpreter for Rust with very small memory footprint and reasonable performance
  • Its virtual machine (VM) is written in only 1.5 KLOC in Rust.
• The minimal implementation of the R7RS-small standard
  • A subset of Chibi Scheme, Gauche, and Guile
• A portable scripting environment that supports even no-std and no-alloc platforms

For the usage and examples, see the documentation.
