Try it on the Playground · Read the Steel book (WIP) About Steel is an embeddable scheme interpreter, with a standalone interpreter/REPL included as well. The language is implemented as a bytecode virtual machine. At the moment, it is mostly compliant with R5RS, only missing let-syntax support. Support for R7Rs is underway. Warning The API is relatively stable, however it may change at any time while pre 1.0. Care will be taken to keep things backwards compatible where possible. Features - R5RS support - Modules, using require and provide much like Racket. - syntax-rules and syntax-case macros. - Easy integration with native Rust functions and structs, either through embedding or via FFI. - Higher order Contracts - Built in immutable data structures, including: - lists - vectors - hashmaps - hashsets For more details, see the book. Getting Started This github repository contains a CLI interpreter. To try it out on the online playground, go to the Steel playground. To get started using a REPL with the crates, make sure you first have Rust installed. Then, clone the repo and run the following command: This will launch a REPL instance that looks something like this: Full install If you'd like to install everything, just run the following command: This will install: - The steel interpreter, steel - The package manager, forge - The dylib installer, cargo-steel-lib (also available via the interpreter) - The steel lang","default_branch":null,"files":null,"tree":[],"storefront":"/r/mattwparas","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/mattwparas/steel/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
