"An atto-subset for the Scheme programming language"
AttoScheme is a small interpreter for the Scheme programming language.
Why Scheme? I like its elegance (Lisp elegance in general).
AttoScheme is designed as a learning tool to help understand how interpreters work. It implements a minimal subset of Scheme and is primarily educational.
- Evaluate basic arithmetic and logical expressions
- Supports lists, symbols, and standard Scheme data types
- Simple REPL (Read-Eval-Print Loop) Note: lambda, closures, and other advanced Scheme features are not yet supported.
AttoScheme was developed as a personal project to explore the implementation of interpreters in OCaml. It is not intended as a production-ready interpreter.
Make sure to have Opam and Dune installed.
Clone the repository.
From the project root directory, run:
dune build
dune exec _build/default/bin/main.exeTest:
dune runtest
Make sure to have Opam and Dune installed.

AttoScheme is still a work in progress. Any contribution to it will be very much appreciated!
What AttoScheme lacks right now:
- Closures
- Lambda expressions
- Pairs
