The MUFL toolchain is installed from npm. You get mufl-compile (the compiler) and mufl (the REPL).

Install from npm

The toolchain is published as the @adapt-toolkit/mufl package. Install it globally to put the binaries on your PATH:

npm install -g @adapt-toolkit/mufl

This gives you two commands:

• mufl-compile — the MUFL compiler. Reads .mufl / .mu / .mm sources, writes content-addressed .muflo artifacts.
• mufl — the MUFL REPL. Useful for quick experiments and for running compiled .muflo files outside an embedding application.

To install it into a project instead of globally, run npm install @adapt-toolkit/mufl and invoke the tools with npx mufl-compile / npx mufl.

What the package contains

Alongside the two binaries, the package bundles everything the compiler needs, in the layout it expects:

• Native prebuilds for the supported platforms.
• The MUFL standard library (mufl_stdlib/) and the meta and transactions libraries.

The standard library and support libraries ship inside the package, so no additional setup is required to compile MUFL.

After installing

Once mufl-compile is on your PATH, the next steps are:

• Learn the MUFL language.
• Read Compile your MUFL code for end-to-end compiler usage.
• Set up the VS Code language server for inline diagnostics.
