Plus, if you use the RequireJS 12 | optimizer, your CoffeeScript files can be translated to JavaScript, and inlined 13 | into optimized layers for fast performance. 14 | 15 | In development, it uses XMLHttpRequest to fetch the .coffee files, so you can only 16 | fetch files that are on the same domain as the HTML page, and most browsers place 17 | restrictions on using XMLHttpRequest from local file URLs, so use a web server to 18 | serve your .coffee files. 19 | 20 | ## Install 21 | 22 | ### Volo 23 | 24 | To install with [Volo](http://volojs.org): 25 | 26 | ``` 27 | volo add require-cs 28 | ``` 29 | 30 | This will install `cs.js` and `coffee-script.js` into the baseUrl folder, and no further configuration is necessary. 31 | 32 | ### Bower 33 | 34 | To install with [Bower](http://bower.io/): 35 | 36 | ``` 37 | bower install require-cs 38 | ``` 39 | 40 | Since bower installs `require-cs` and `coffee-script` into separate folders, add the following RequireJS [package configuration](http://requirejs.org/docs/api.html#packages): 41 | 42 | ```javascript 43 | { 44 | baseUrl: '..path_to_packages..' 45 | packages: [ 46 | { 47 | name: 'cs', 48 | location: 'require-cs', 49 | main: 'cs' 50 | }, 51 | { 52 | name: 'coffee-script', 53 | location: 'coffeescript', 54 | main: 'extras/coffee-script' 55 | } 56 | ] 57 | } 58 | ``` 59 | 60 | ### Manual Download 61 | 62 | 1) Download CoffeeScript for the browser that registers as an AMD module. You 63 | can do that by using a "raw" GitHub URL. It takes the form of: 64 | 65 | https://raw.github.com/jashkenas/coffee-script/[BRANCH-OR-VERSION]/extras/coffee-script.js 66 | 67 | Example links: 68 | 69 | * [master](https://raw.github.com/jashkenas/coffee-script/master/extras/coffee-script.js) 70 | * [1.8.0](https://raw.github.com/jashkenas/coffee-script/1.8.0/extras/coffee-script.js) 71 | 72 | Place this in the directory that is your 73 | [baseUrl](http://requirejs.org/docs/api.html#config-baseUrl) for your project, 74 | or set up a [paths config](http://requirejs.org/docs/api.html#config-paths) 75 | for it for the module ID `coffee-script`. The cs.js file specifies `coffee-script` 76 | as a dependency. 77 | 78 | 2) Download the [latest version of cs.js](https://raw.github.com/jrburke/require-cs/latest/cs.js). 79 | 80 | ## Usage 81 | 82 | Reference CoffeeScript files via the cs! plugin name. For example, to load 83 | the `app.coffee` file that is in your baseUrl directory: 84 | 85 | require(['cs!app'], function (app) { 86 | 87 | }); 88 | 89 | Or, if creating a module that depends on `util.coffee`: 90 | 91 | define(['cs!util'], function (util) { 92 | util.doSomething(); 93 | }); 94 | 95 | If you are using define() in a module written with CoffeeScript: 96 | 97 | define ['cs!util'], (util) -> 98 | util.doSomething 99 | 100 | [Literate CoffeeScript](http://coffeescript.org/#literate) was introduced in CoffeeScript 1.5.0. 101 | To utilize this feature with this plugin you will need to have downloaded >= 1.5.0 102 | of CoffeeScript and qualify the file (with extension) of the literate module you wish to use. 103 | 104 | A dependency on the literate module `app.litcoffee`: 105 | 106 | require ['cs!app.litcoffee'], (litapp) -> 107 | litapp.foo() 108 | # ... 109 | 110 | Or a dependency on the literate module `util.coffee.md`: 111 | 112 | define ['cs!util.coffee.md'], (litutil) -> 113 | litutil.doSomething() 114 | # ... 115 | 116 | Note: This plugin supports a mixture of literate and regular CoffeeScript files in the 117 | same project. 118 | 119 | **VERY IMPORTANT**: Only define anonymous modules using CoffeeScript. Otherwise, 120 | the optimization work will not happen correctly — the name of the module is changed 121 | to allow inlining of the translated JS content. 122 | 123 | ## Complete web project 124 | 125 | The **demo** directory shows a complete web example. See the demo/index.html file 126 | as the entry point into the demo. It is not a fancy demo, just shows basic use. 127 | 128 | If you have node installed and need to run a web server to try out the demo, 129 | in this directory run `npm install send`, then start up the demo web server 130 | by running: 131 | 132 | node demoserver.js 133 | 134 | # Optimizing 135 | 136 | See **demo/build.sh** for an example build script that drives the optimizer with 137 | the **demo/build.js** build config. 138 | 139 | The build will generate a **demo-build** directory with the optimized files. Where 140 | the unoptimized demo directory will load 7 files, the optimized one only loads 2, 141 | and the CoffeeScript files have been converted to JavaScript. Since all the CoffeeScript 142 | modules have been converted to JS after the build, the CoffeeScript module and 143 | the source cs.js module are not included/needed in the built file. 144 | 145 | If you want to do dynamic loading of CoffeeScript files after a build, then 146 | comment out `stubModules: ['cs']` and `exclude: ['coffee-script']` from the build 147 | file so that they will be included in the build. 148 | 149 | ## License 150 | 151 | MIT 152 | 153 | ## Code of Conduct 154 | 155 | [jQuery Foundation Code of Conduct](https://jquery.org/conduct/). 156 | -------------------------------------------------------------------------------- /demo/lib/domReady.js: -------------------------------------------------------------------------------- 1 | /** 2 | * @license RequireJS domReady 0.1.0 Copyright (c) 2010-2011, The Dojo Foundation All Rights Reserved. 3 | * Available via the MIT or new BSD license. 4 | * see: http://github.com/jrburke/requirejs for details 5 | */ 6 | /*jslint strict: false, plusplus: false */ 7 | /*global require: false, define: false, requirejs: false, 8 | window: false, clearInterval: false, document: false, 9 | self: false, setInterval: false */ 10 | 11 | 12 | define(function () { 13 | var isBrowser = typeof window !== "undefined" && window.document, 14 | isPageLoaded = !isBrowser, 15 | doc = isBrowser ? document : null, 16 | readyCalls = [], 17 | readyLoaderCalls = [], 18 | //Bind to a specific implementation, but if not there, try a 19 | //a generic one under the "require" name. 20 | req = requirejs || require || {}, 21 | oldResourcesReady = req.resourcesReady, 22 | scrollIntervalId; 23 | 24 | function runCallbacks(callbacks) { 25 | for (var i = 0, callback; (callback = callbacks[i]); i++) { 26 | callback(doc); 27 | } 28 | } 29 | 30 | function callReady() { 31 | var callbacks = readyCalls, 32 | loaderCallbacks = readyLoaderCalls; 33 | 34 | if (isPageLoaded) { 35 | //Call the DOM ready callbacks 36 | if (callbacks.length) { 37 | readyCalls = []; 38 | runCallbacks(callbacks); 39 | } 40 | 41 | //Now handle DOM ready + loader ready callbacks. 42 | if (req.resourcesDone && loaderCallbacks.length) { 43 | readyLoaderCalls = []; 44 | runCallbacks(loaderCallbacks); 45 | } 46 | } 47 | } 48 | 49 | /** 50 | * Add a method to require to get callbacks if there are loader resources still 51 | * being loaded.
