history

Project history and usage

LunarML is a Standard ML compiler whose distinguishing package-manager pitch is that it emits Lua and JavaScript rather than native code. Its upstream README describes it as a compiler for the full SML '97 language with signatures, functors, a subset of the Basis Library, an ML Basis system for multi-file projects, and targets for Lua, LuaJIT, Node.js, and web JavaScript.

Project history

The public GitHub repository was created in 2018 under ARATA Mizuki's minoki account. The project has since developed as a niche cross-runtime Standard ML implementation: the documentation is maintained as Sphinx/Read the Docs material, and the README documents prebuilt binaries, Docker usage, and source builds via MLton.

By the v0.3.0 release line, LunarML packaged the compiler as native binaries as well as precompiled Lua and Node.js scripts. The README warns that script-compiled LunarML is slower than the native binary, which reflects the project's practical packaging concern: making the compiler runnable in several host environments while preserving a serious-use native path.

Adoption history

LunarML remains a specialist language-tooling package rather than a mass-market runtime. The supplied package metadata lists Homebrew and Nix packages, and the GitHub repository metadata shows a modest but visible audience for an SML-to-Lua/JavaScript compiler.

Its adoption story is strongest among language implementers and users who want Standard ML code to run in ecosystems where Lua or JavaScript is the deployment substrate.

How it is used

The core command is `lunarml compile [options] input.(sml|mlb)`. Users choose targets such as Lua 5.3+, LuaJIT, Node.js ES modules, or web JavaScript, and can produce executable-style programs or modules.

The README also documents `check`, `help`, and `version` subcommands, Docker invocation, `make install`, and build/test targets for Lua, LuaJIT, and Node.js back ends.

Why package nerds care

LunarML is interesting to package nerds because it packages a traditionally academic language in a portable, script-friendly way. A Homebrew or Nix install can turn SML source into Lua or JavaScript output without requiring users to assemble a full bespoke compiler toolchain.

The package also shows the tension common in language packages: convenient precompiled scripts exist for reach, while the upstream docs still steer serious users toward the native compiler.
