livereactload - Live code editing with Browserify and React

•    Javascript

Live code editing with Browserify and React. Hot reloading is de facto in today's front-end scene but unfortunately there isn't any decent implementation for Browserify yet. This is shame because (in my opinion) Browserify is the best bundling tool at the moment.

doitlive - Because sometimes you need to do it live

•    Python

doitlive is a tool for live presentations in the terminal. It reads a file of shell commands and replays the commands in a fake terminal session as you type random characters. Requires Python >= 2.7 or >= 3.5 with pip.

codecombat - Game for learning how to code.

•    CoffeeScript

NOTE: The process for setting up the dev environment has changed. Please refer to the docs for details. It's both a startup and a community project, completely open source under the MIT and Creative Commons licenses. It's the largest open source CoffeeScript project by lines of code, and since it's a game (with really cool tech), it's really fun to hack on. Join us in teaching the world to code! Your contribution will go on to show millions of players how cool programming can be.

mud - MUD is a layer over Overtone to make live composition more powerful and immediate.

•    Clojure

MUD is a layer over Overtone which focuses on immediacy of expression and creation. Overtone is extremely powerful at the cost of verbosity. Live coding requires quite a lot of code. Snippet expansion can help alleviate but it does hinder the range of expression and clutters the visual experience for the audience reading along with the code.

shaderview - Light show for live coding

•    GLSL

Shaderview is an app for creating visuals using OpenGl Shaders and it uses OSC messages to communicate changes in state. For example when live coding music you could send an OSC message when the drum sample played and in turn your shader could do something with that signal, like flashing of white. Since Shaderview does everything through OSC, there is no tie to a specific client language.

cl-patterns - Library for conveniently(?) writing patterns to generate or process (a)musical sequences of mathematically (un)related (non-)compound values in Lisp

•    Common

A library for conveniently(?) writing patterns to generate or process (a)musical sequences of mathematically (un)related (non-)compound values in Lisp. In addition to emulating most of SuperCollider’s patterns system, another goal is to further extend it with more tools and more ways to write patterns/sequences. The most obvious example being a “drum sequence” notation like k - - - k - - - k - - - k - - - for a four-to-the-floor beat. The idea is that Lisp’s macros should make it possible to more expressively write music with code.
