A programming language as an infrastructure for sound and music.

https://mimium.org (A documentation for v2 is under preparation!)

mimium(MInimal-Musical-medIUM) is a programming language for sound and music.

mimium is made to be an infrastructure for distributing music in a form of a source code, not only a tool for musicians and programmers.

Its semantics are inspired from several modern programming languages for sound such as Faust, Kronos and Extempore.

A minimal example below generates a sinewave of 440Hz.

// minimal.mmm
let twopi = 3.141595*2.0
fn dsp(){
  sin(now * 440.0 * twopi / samplerate)
}

A special keyword self can be used in function, which is a last return value of the function. This enables an easy and clean expression of feedback connection of signal chain.

fn lpf(input,fb){    
     (1.0-fb)*input + fb*self
}

Also, the language design is based on the call by value lambda calculus, so the higher-order functions are supported to express generative signal graph like replicatiing multiple oscillators.

fn replicate(n,gen){
    if (n>0.0){
        let c = replicate(n - 1.0,gen)
        let g = gen()
        |x,rate| g(x,rate) + c(x+100.0,rate+0.1)
    }else{
        |x,rate|  0
    }
}

mimium is a statically typed language but the most of type annotations can be omitted by the type inference system. If you are interested in the theoritical background of mimium, see the paper about mimium.

This repository is for a mimium version 2, all the code base is rewritten in Rust while the original was in C++, and semantics of the language was re-designed. The codes are still very under development.

Installation

An easy way to start mimium is using Visual Studio Code Extension. You can run opening .mmm file from the command palette.

Also you can download the latest CLI tool mimium-cli from GitHub Release.

Development

See Development section.

Contributing

There's no concrete way for contributing to the mimium project for now but any type of contribution (bugfix, code refactoring, documentation, showing the usecases, etc).

(However, because the mimium is still early stage of the development and there's much things to do, the proposal or request for new feature without Pull Request will not be accepted.)

Take a look at Code of Conduct before you make contribution.
