Mond is an experimental functional language with a Lisp-inspired syntax and ML-style static types that targets the BEAM.

To get started read the book

This repo is a mono-repo that contains the core of the Mond programming language, including:

• bahn - the build tool for the Mond programming language
• mond-format - a library for formatting Mond source code
• mond-lsp - a library for the Mond lsp (language server protocol)
• mondc - the compiler for the Mond programming language
• book - the Mond programming language book
• samples - some Mond samples

Other parts of the ecosystem are hosted in separate repos:

• standard library
• otp

AI Policy

Mond has proved a useful project in exploring using LLMs / agentic AI for increasing productivity. At rough estimate the repo is currently 70% LLM generated and 30% human written. All AI generated code is reviewed by a human and considerable effort has been made on code coverage and ensuring that the AI generated code behaves as intended.
