// Memoize a function -- creates a new function that will cache the results of
// the first return by serializing inputs as a key.
// 
// * `fn`: the function to be memoized.
// * `hash`: a function to create the cache key.
// * `out`: a function to process memoized data on the way out. Useful if you need

// KV.js
// Hash iteration functions

// Set a value on an object at field, returning object.
function set(object, key, value) {
  // Set value on object at key.
  object[key] = value;
  // Return object.

Basic stuff

Add an element to an indexed object, mutating it. Returns object.

add = (indexed, item) ->
  Array.prototype.push.call(indexed, item)
  indexed

Generic reduction over anything. This will come in handy for iterating

// Foldable.js
// =============================================================================
//
// Fold DOM elements based on whether they match a query string.
//
// How:
//
//     var foldableParagraphs = document.querySelectorAll('p.foldable');
//     foldable(foldableParagraphs)
//

gordonbrander

// Returns an array of all indexes at which `pattern` can be found in `string`.
function indexesOf(string, pattern) {
  var i = -1;
  var indexes = [];
  // We mutate `i` in place with the result of `indexOf`. We also use the last
  // value of `i + 1` to continue seeking from. Any index found is pushed into
  // the `indexes` array. If we ever get `-1` as the result of `indexOf`, we
  // stop looping.
  while((i = string.indexOf(pattern, i + 1)) !== -1) indexes.push(i);
  return indexes;

// Hashtext: the no-markup markup language.
// Quick-and-dirty Twitter-style text rendering.
//
// * Auto-paragraphatize and linebreak newlines.
// * Auto-link URLs (and prettify them, too).
// * Expand #hashtags into something useful (your choice).
