A named AMD is safest and most robust // way to register. Lowercase avalon is used because AMD module names are // derived from file names, and Avalon is normally delivered in a lowercase // file name. Do this after creating the global so that if an AMD module wants // to call noConflict to hide this version of avalon, it will work. // Note that for maximum portability, libraries that are not avalon should // declare themselves as anonymous modules, and avoid setting a global if an // AMD loader is present. avalon is a special case. For more information, see // https://github.com/jrburke/requirejs/wiki/Updating-existing-libraries#wiki-anon if (typeof define === "function" && define.amd) { define("avalon", [], function() { return avalon }) } // Map over avalon in case of overwrite var _avalon = window.avalon avalon.noConflict = function(deep) { if (deep && window.avalon === avalon) { window.avalon = _avalon } return avalon } // Expose avalon identifiers, even in AMD // and CommonJS for browser emulators if (noGlobal === void 0) { window.avalon = avalon } return avalon }));
