Replace search for generators with the new search used on the website

[Haroenv]

Type of issue

feature request

Why?

once yeoman/yeoman.io#763 is merged and we're all happy with it, we can replace the search to be consistent with what's on the site

Relevant code

The code to change will be around this:

yo/lib/routes/install.js

Lines 44 to 102 in 479250a

	const getAllGenerators = _.memoize(() => npmKeyword('yeoman-generator'));
	function searchMatchingGenerators(app, term, cb) {
	function handleBlacklist(blacklist) {
	const installedGenerators = app.env.getGeneratorNames();
	getAllGenerators().then(allGenerators => {
	cb(null, allGenerators.filter(generator => {
	if (blacklist.indexOf(generator.name) !== -1) {
	return false;
	}
	if (installedGenerators.indexOf(generator.name) !== -1) {
	return false;
	}
	return generatorMatchTerm(generator, term);
	}));
	}, cb);
	}
	got('http://yeoman.io/blacklist.json', {json: true})
	.then(response => handleBlacklist(response.body))
	.catch(() => handleBlacklist([]));
	}
	function fetchGeneratorInfo(generator, cb) {
	packageJson(generator.name).then(pkg => {
	const official = OFFICIAL_GENERATORS.indexOf(pkg.name) !== -1;
	const mustache = official ? chalk.green(` ${figures.mustache} `) : '';
	cb(null, {
	name: generator.name.replace(/^generator-/, '') + mustache + ' ' + chalk.dim(pkg.description),
	value: generator.name,
	official: -official
	});
	}).catch(cb);
	}
	function searchNpm(app, term) {
	const promise = new Promise((resolve, reject) => {
	searchMatchingGenerators(app, term, (err, matches) => {
	if (err) {
	reject(err);
	return;
	}
	async.map(matches, fetchGeneratorInfo, (err2, choices) => {
	if (err2) {
	reject(err2);
	return;
	}
	resolve(choices);
	});
	});
	});
	return promise.then(choices => promptInstallOptions(app, sortOn(choices, ['official', 'name'])));
	}

There algoliasearch could be used with the same searchParameters as in yeoman/yeoman.io#763 (comment)
