# fuzzy [![Build Status](https://img.shields.io/travis/mattyork/fuzzy/master.svg)](https://travis-ci.org/mattyork/fuzzy) [![npm version](https://badge.fury.io/js/fuzzy.svg)](https://badge.fury.io/js/fuzzy) 1k standalone fuzzy search / fuzzy filter a la Sublime Text's command-p fuzzy file search. Works in both node and browser. [![Example](http://i.imgur.com/obzCQq7.gif)](http://htmlpreview.github.io/?https://github.com/mattyork/fuzzy/blob/master/examples/disney.html) Try it yourself: [Disney Character Search Example](http://htmlpreview.github.io/?https://github.com/mattyork/fuzzy/blob/master/examples/disney.html) ## Get it Node: ```bash $ npm install --save fuzzy $ node > var fuzzy = require('fuzzy'); > console.log(fuzzy) { test: [Function], match: [Function], filter: [Function] } ``` Browser: ```html ``` ## Use it Padawan: Simply filter an array of strings. ```javascript var list = ['baconing', 'narwhal', 'a mighty bear canoe']; var results = fuzzy.filter('bcn', list) var matches = results.map(function(el) { return el.string; }); console.log(matches); // [ 'baconing', 'a mighty bear canoe' ] ``` Jedi: Wrap matching characters in each string ```javascript var list = ['baconing', 'narwhal', 'a mighty bear canoe']; var options = { pre: '<', post: '>' }; var results = fuzzy.filter('bcn', list, options) console.log(results); // [ // {string: 'aoing' , index: 0, score: 3, original: 'baconing'}, // {string: 'a mighty ear aoe', index: 2, score: 3, original: 'a mighty bear canoe'} // ] ``` Jedi Master: sometimes the array you give is not an array of strings. You can pass in a function that creates the string to match against from each element in the given array ```javascript var list = [ {rompalu: 'baconing', zibbity: 'simba'} , {rompalu: 'narwhal' , zibbity: 'mufasa'} , {rompalu: 'a mighty bear canoe', zibbity: 'saddam hussein'} ]; var options = { pre: '<' , post: '>' , extract: function(el) { return el.rompalu; } }; var results = fuzzy.filter('bcn', list, options); var matches = results.map(function(el) { return el.string; }); console.log(matches); // [ 'aoing', 'a mighty ear aoe' ] ``` ## Examples Check out the html files in the [examples](https://github.com/mattyork/fuzzy/tree/master/examples) directory.

Search improvement: behave a bit more like sublime text by getting the BEST match in a given string, not just the first. For example, searching for 'bass' in 'bodacious bass' should match against 'bass', but it currently matches like so: `odciou bas`. There is a test already written, just need to implement it. Naive O(n^2) worst case: find every match in the string, then select the highest scoring match. Should benchmark this against current implementation once implemented Also, "reactive rice" would be `active re` 2. Search feature: Work on multiple strings in a match. For example, be able to match against 'stth' against an object { folder: 'stuff', file: 'thing' } 3. Async batch updates so the UI doesn't block for huge sets. Or maybe Web Workers? 4. Performance performance performance!
