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][r7rs-small]
- 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.
