Twitter Supercollider App

There are some people twittering supercollider code. They do sound generating apps in 140 characters or less! I've just created some code to fetch and play these. It uses a yahoo pipe which looks for tweets tagged with #supercollider and which seem to contain a playable piece of code. It also does some sanitizing to ignore potentially evil content.

This is a first draft, so it requires a helper script, written in bash, which is called fetch.sh:

#!/bin/bash

curl http://pipes.yahoo.com/pipes/pipe.run?_id=sqg4I0kl3hGkoIu9dPQQIA\&_render=r
ss  >   /tmp/rss.xml

The SC code is:

(
r = { 


 Routine.new({
 
  var code, new_code, syn, doc, elements;
  
  inf.do({
  
   "fetching".postln;
  
   "/path/to/fetch.sh".unixCmd;
   
   doc = DOMDocument.new("/tmp/rss.xml");
   doc.read(File.new("/tmp/rss.xml", "r"));
   elements = doc.getElementsByTagName("description");
   
   
   elements.notNil.if ({
   
    new_code = elements.last.getText;
   
    ((new_code == code).not).if ({
   
     code = new_code;
   
     code.postln;
      
     (syn.notNil).if ({ syn.free; s.freeAll; });
     syn = code.interpret;
    });
   });
   60.yield;
  });
 });
 
};

)

r.play;
