limut

Limut

Live coding music and visuals in the browser. Inspired by FoxDot with a desire to make it more accessible by running in any modern browser with no installation. Approach to visuals inspired by Crash Server’s video player, and shadertoy :-)

Documentation

Documentation is available in the page itself, underneath the console.

Try it

Try it at https://sdclibbery.github.io/limut/

Example limut code can be pasted into the editor to see what Limut can do; this can be found on the page under the editor and console windows, or there are many examples (including some technical tests) at https://github.com/sdclibbery/limut/blob/master/examples.limut

Please report problems / bugs / browser issues etc as github issues at https://github.com/sdclibbery/limut/issues

Releases and breaking changes

Normal development should be backwards compatible. There is no specific log of added functionality (apart from the commit log).

Occasionally, breaking changes are introduced; when this happens, a new github release is produced: https://github.com/sdclibbery/limut/releases to document the upgrade path for user code.

Electron app

Limut can be run as a website, or packaged into a desktop web app. With npm installed, run npm install to install electron, and then npm start to run the electron app. There are no prepackaged versions available at present (pull requests welcome).

Code Editor

Limut uses the CodeMirror editor (https://codemirror.net). This provides syntax coloring.

Development

Run locally by firing up ./server.sh and connecting a browser to http://localhost:8000/?test . The unit tests run on page load when the ?test url parameter is present; view output in the browser console.

Waveforms

Some waveform tables are taken from the Web Audio Samples repo, under the Apache license: https://github.com/GoogleChromeLabs/web-audio-samples

The Adventure Kid WaveForms are included for use as wavetable samples.

The WaveEdit Online wave tables are included.

Shaders

Many shaders are based on ones from https://www.shadertoy.com/ , and the shadertoy synth uses the Shadertoy.com API to load shaders directly from shadertoy.
