Completely avoiding namespace collisions for 2-byte abbreviated keys for the document object

README.md

This version uses all possible ASCII variable names, i.e. È and the like! Don't know why I still have 4-5 collisions depending on environment.

namespaceHash.js

/**
 * Automatically makes a 2-byte hash namespace of global objects.
 * Since .xxx is the same length as [xx], don't process unless > 3 chars
 */
var d = document;
var namespace = {};var coll = 0;
(function(v, m, n) {
  m = {0:36, 37:28, 91:6, 123:69, 215:2, 247:2};
  function c(x, q) {
    for(q in m)
      if(x >= q) x += m[q];
    if(x > 255) return c(x - 256);
    return String.fromCharCode(x);
  }
  for(n in d)
    if(n.length > 3) {
      v = n.split('').reduce(function(j, k, i) { return j + i * k.charCodeAt(0) }, 0);
      console.log(v);
      v = c(v % 256) + c(Math.floor(v / 256) % 256);
      window[v] = n;

// debug
      namespace[v] = namespace[v] || [];
      if(namespace[v].length) coll++;
      namespace[v].push(n);
// end

    }
})();

alert(coll + ' collisions');
