Scruby ¶ ↑

Is a bare-bones SuperCollider livecoding library for Ruby, it provides comunication with a remote or local scsynth server and SynthDef creation with a in a similar way to Sclang.

SynthDef creation and sending is robust but some features are not implemented such as SynthDef variations and others I may not be aware of.

livecode.rb executable is located in the bin directory and a TextMate bundle included in extras permits livecoding from TextMate, comunication is thrugh *nix pipes. Similar functionality shouldn’t be too dificult to implement from Emacs or Vim.

USAGE¶ ↑

require 'scruby'

s = Server.new
s.boot

SynthDef.new :fm do |freq, amp, dur|
  mod_env = EnvGen.kr Env.new( d(600, 200, 100), d(0.7,0.3) ), 1, :timeScale => dur
  mod     = SinOsc.ar freq * 1.4, :mul => mod_env
  sig     = SinOsc.ar freq + mod
  env     = EnvGen.kr Env.new( d(0, 1, 0.6, 0.2, 0.1, 0), d(0.001, 0.005, 0.3, 0.5, 0.7) ), 1, :timeScale => dur, :doneAction => 2
  sig     = sig * amp * env
  Out.ar  0, [sig, sig]
end.send

Synth.new :fm, :freq => 220, :amp => 0.4, :dur => 1

To start a live coding session:

$ livecode

The gem includes a TextMate bundle for interacting with the live coding session, currently there is no cli installation but is located in the extras folder, if a file has .live.rb extension the bundle is loaded.

Text can be sent from textmate to the live session pressing enter, either a selection or a bunch of code.

Sending text from another editor or the shell:

$ echo '...some ruby code...' | tr '\n' '∂' > `ruby -e "require 'tempfile'; puts Dir.tmpdir"`/ruby_live.pipe

TODO¶ ↑

Receive OSC messages from SuperCollider
