CoffeeScript helpers

Usage

{helpers,p_fun,p_exec} = require 'coffeescript-helpers'

helpers

Contains the helpers installed by CoffeeScript.

@helpers = helpers = """
var slice = [].slice;
var hasProp = {}.hasOwnProperty;
var bind = function(fn, me){
return function(){ return fn.apply(me, arguments); };
};
var extend = function(child, parent) {
for (var key in parent) {
if (hasProp.call(parent, key)) child[key] = parent[key];
}
function ctor() { this.constructor = child; }
ctor.prototype = parent.prototype;
child.prototype = new ctor();
child.__super__ = parent.prototype;
return child;
};
var indexOf = [].indexOf || function(item) {
for (var i = 0, l = this.length; i < l; i++) {
if (i in this && this[i] === item) return i;
} return -1; };
var modulo = function(a, b) { return (+a % (b = +b) + b) % b; };
""".replace /\n/g, ''

p_fun

Map a (compiled) CoffeeScript function to a JavaScript function with the proper helpers installed. It is intended to be used for CouchDB map functions, for example.

@p_fun = (extra,f) ->
  if not f?
    f = extra
    extra = ''
  return "(function (){#{extra} #{helpers} return #{f};})();"

p_exec

Map a (compiled) CoffeeScript function so that it actually gets executed. It is intended to wrap functions server-side so that they execute client-side (in ZappaJS for example).

@p_exec = (extra,f) ->
  if not f?
    f = extra
    extra = ''
  return "(function (){#{extra} #{helpers} return (#{f})();})();"
