tikurahul / chrome-omnibox-awesomeness
Created August 7, 2013 23:13
A technique to supercharge Chome's "Manage Search Engines" feature. Map this JavaScript URL to a Search Engine (e.g super), and then you can do something like: super [TAB] "code packageName branchName" which will get mapped to "https://code.amazon.com/packages/packageName/trees/branchName/"

javascript:
var patterns = {
'vs': 'https://devcentral.amazon.com/ac/brazil/directory/version-set/packages/{0}/{1}',
'code': 'https://code.amazon.com/packages/{0}/trees/{1}/'
};
var pattern = decodeURIComponent('%s');
var keys = pattern.split(' ');

var args = keys ? keys.slice(1) : [];

Flow control with Generators

Please correct me if I am making incorrect assumptions:
The way everything works is
async(function *() {
// generator expression
// returns multiple promises
var x = yield $.ajax('http://x....');
var y = yield $.ajax('http://y....');
