Project history and usage

Millet is a Rust language server for Standard ML by Andrew Davis. Davis introduced it publicly in a July 2, 2022 blog post, explaining that the idea came from his experience as a Carnegie Mellon undergraduate and teaching assistant for 15-150, an introductory functional programming course taught in Standard ML. The original motivation was to reduce the friction of compiler-error loops and give SML programmers editor feedback similar to modern language ecosystems.

Project history

The same development narrative describes an early 2020 first attempt, a dormant period, and a May 2022 revival after Davis saw interest from a CMU student Discord. The revived implementation was rewritten around language-server needs: partial and malformed code should still produce useful diagnostics, and the project split the old code into crates, modernized tests, and replaced the earlier design with a more robust implementation.

Adoption history

Millet's practical role is editor tooling for a niche language rather than a general compiler. Its README says it analyzes SML without running it and offers inline diagnostics, hover type and documentation, inlay hints, jump to definition, completions, code actions, document symbols, and find references. It understands multi-file projects through SML/NJ Compilation Manager files and ML Basis files, with configuration through `millet.toml`, VS Code settings, language-server initialization, and ML Basis annotations.

How it is used

The package-manager niche is small but useful: official distribution includes a VS Code extension, Open VSX publication, and GitHub release binaries, while community packaging includes Homebrew, Nixpkgs, and AUR. It sits alongside SML/NJ and MLton rather than replacing them; users still need an SML implementation to run code, while Millet supplies the language-server layer for VS Code-compatible editors and other LSP-capable editors.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
