Stak Scheme

Install

This page explains how to install Stak Scheme as command line tools or libraries. By reading this page, you will learn:

  • How to install Stak Scheme as command line tools.
  • How to install Stak Scheme as libraries in Rust crates.

Command line tools

Interpreters

To install the Stak Scheme interpreter, run the following command in your terminal.

Terminal window
cargo install stak

Now, you can run programs written in R7RS Scheme with the stak command as follows.

Terminal window
stak hello.scm

The content of the hello.scm would look like:

Terminal window
(import (scheme base))


(write-string "Hello, world!\n")

Development tools

To install development tools of Stak Scheme, run the following command in your terminal:

Terminal window
cargo install stak-compile stak-interpret

The stak-compile command is a Scheme-to-bytecode compiler. The stak-interpret command is a bytecode interpreter that ingests and runs bytecode files built by the stak-compile command.

Libraries

To install Stak Scheme as a library in your Rust crate, run the following commands in your terminal.

Terminal window
cargo add stak
cargo add --build stak-build
cargo install stak-compile

The crates have different roles:

  • The stak crate provides scripting engines, virtual machines, and utilities to run Scheme programs embedded in Rust.
  • The stak-build crate compiles Scheme programs in build.rs build scripts in Rust crates.
  • The stak-compile crate is a Stak Scheme compiler to compile Scheme programs into bytecodes.
