Therefore +files are correctly cached by the browser AND your users always +get the latest version when you re-deploy! + +== Credit + +This Rails Plugin was inspired by Cal Henderson's article +"Serving Javascript Fast" on Vitamin: +http://www.thinkvitamin.com/features/webapps/serving-javascript-fast + +It also uses the Ruby Javascript Minifier created by +Douglas Crockford. +http://www.crockford.com/javascript/jsmin.html + +== Key Features + +* Merges and compresses javascript and css when running in production. +* Uses uncompressed originals when running in development. +* Handles caching correctly. (No querystring parameters - filename timestamps) +* Uses subversion revision numbers instead of timestamps if within a subversion controlled directory. +* Guarantees new version will get downloaded the next time you deploy. + +== Components + +* Rake Task for merging and compressing javascript and css files. +* Helper functions for including these javascript and css files in your RHTML. +* YAML configuration file for mapping javascript and css files to merged versions. +* Rake Task for auto-generating the YAML file from your existing javascript files. + +== How to Use: + +1. Download and install the plugin: + ./script/plugin install http://sbecker.net/shared/plugins/asset_packager + +2. Run the rake task "asset:packager:create_yml" to generate the /config/asset_packages.yml file the first time. You +will need to reorder files under 'base' so dependencies are loaded in correct order. Feel free +to rename or create new file packages. + +Example with multiple merged files: + +--- +javascripts: +- base: + - prototype + - effects + - controls + - dragdrop + - application +- secondary: + - foo + - bar +stylesheets: +- base: + - screen + - header +- secondary: + - foo + - bar + +3. Run the rake task "asset:packager:build_all" to generate the compressed, merged versions for each package. + +4. Use the helper functions whenever including these files in your application. See below for examples. + +5. Potential warning: css compressor function currently removes css comments. This might blow away some css hackery. To disable comment removal, comment out /lib/synthesis/asset_package.rb line 167. + +== Javascript Examples + +Example call: + <%= javascript_include_merged 'prototype', 'effects', 'controls', 'dragdrop', 'application', 'foo', 'bar' %> + +In development, this generates: + + + + + + + + +In production, this generates: + + + +Now supports symbols and :defaults as well: +<%= javascript_include_merged :defaults %> +<%= javascript_include_merged :foo, :bar %> + +== Stylesheet Examples + +Example call: + <%= stylesheet_link_merged 'screen', 'header', 'foo', 'bar' %> + +In development, this generates: + + + + + +In development this generates: + +== License +Copyright (c) 2006 Scott Becker - http://synthesis.sbecker.net + +Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
