win7下，Ant 配合yuicompressor對js和css進行合并、壓縮、拷貝處理

標籤：yuicompressor   ant   js壓縮   css壓縮   

本文基於windows7系統，mac上或許更簡單些。本文參閱了無墨來點睛的文章http://www.cnblogs.com/catprayer/archive/2011/08/03/2126719.html，再此說明。

花了點時間，總算是實驗成功，demo地址：http://pan.baidu.com/s/1c0dGm1i

ant可以去官網下載，地址是：http://ant.apache.org/ ，yuicompressor也可以去官網下一個https://github.com/yui/yuicompressor

demo的使用的ant版本是apache-ant-1.8.2，yuicompressor版本是yuicompressor-2.4.6。

另外由於ant是需要java運行環境的（一開始沒看ant的說明，為此浪費了些時間），1.8的版本至少需要1.4的java jdk，可以從這裡查閱：http://ant.apache.org/faq.html

java環境可以到官網下載，地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html,請先安裝java環境，然後配置java的環境變數，

配置好後可在cmd-》dos下輸入java，查閱是否安裝成功。然後配置ant的環境變數，配置好後，同樣測試是否安裝成功，cmd->dos->輸入ant，出現類似下面的內容表示

安裝成功：

到此環境才配置成功。下面看demo結構

我這是在vs裡面建的小工程，僅僅是為了編寫build的xml檔案而已，再次說明，僅僅為編寫xml，你完全可以自己手動在檔案夾中做的。

其中核心的是build.xml檔案，結構如下：

<?xml version="1.0" encoding="utf-8"?><project default="compress" basedir="F:\js\cc\deploymentTes\web" name="core">  <!-- 項目的 web 路徑 -->  <property name="path" value="F:\js\cc\deploymentTes\web" />  <!-- 部署的輸出路徑 -->  <property name="targetDir" value="F:\js\cc\deploymentTes\build_output\asset" />  <!-- 源檔案路徑(src) -->  <property name="code.src" value="src" />  <!-- !!!

build.bat的批次檔是為了調用ant的，它的內容是：

./apache-ant-1.8.2/bin/ant -f ./build.xml

是要運行bat檔案即可，至於ant和yuicompressor xml文法解析說明，可以看文檔，非常詳細，而且你下載的demo裡面有詳細使用說明：

下面摘錄的是yuicompressor的readme：

==============================================================================YUI Compressor==============================================================================NAME  YUI Compressor - The Yahoo! JavaScript and CSS CompressorSYNOPSIS  Usage: java -jar yuicompressor-x.y.z.jar [options] [input file]  Global Options    -h, --help                Displays this information    --type <js|css>           Specifies the type of the input file    --charset <charset>       Read the input file using <charset>    --line-break <column>     Insert a line break after the specified column number    -v, --verbose             Display informational messages and warnings    -o <file>                 Place the output into <file> or a file pattern.                              Defaults to stdout.  JavaScript Options    --nomunge                 Minify only, do not obfuscate    --preserve-semi           Preserve all semicolons    --disable-optimizations   Disable all micro optimizationsDESCRIPTION  The YUI Compressor is a JavaScript compressor which, in addition to removing  comments and white-spaces, obfuscates local variables using the smallest  possible variable name. This obfuscation is safe, even when using constructs  such as 'eval' or 'with' (although the compression is not optimal is those  cases) Compared to jsmin, the average savings is around 20%.  The YUI Compressor is also able to safely compress CSS files. The decision  on which compressor is being used is made on the file extension (js or css)GLOBAL OPTIONS  -h, --help      Prints help on how to use the YUI Compressor  --line-break      Some source control tools don't like files containing lines longer than,      say 8000 characters. The linebreak option is used in that case to split      long lines after a specific column. It can also be used to make the code      more readable, easier to debug (especially with the MS Script Debugger)      Specify 0 to get a line break after each semi-colon in JavaScript, and      after each rule in CSS.  --type js|css      The type of compressor (JavaScript or CSS) is chosen based on the      extension of the input file name (.js or .css) This option is required      if no input file has been specified. Otherwise, this option is only      required if the input file extension is neither 'js' nor 'css'.  --charset character-set      If a supported character set is specified, the YUI Compressor will use it      to read the input file. Otherwise, it will assume that the platform's      default character set is being used. The output file is encoded using      the same character set.  -o outfile      Place output in file outfile. If not specified, the YUI Compressor will      default to the standard output, which you can redirect to a file.      Supports a filter syntax for expressing the output pattern when there are      multiple input files.  ex:          java -jar yuicompressor.jar -o '.css$:-min.css' *.css      ... will minify all .css files and save them as -min.css  -v, --verbose      Display informational messages and warnings.JAVASCRIPT ONLY OPTIONS  --nomunge      Minify only. Do not obfuscate local symbols.  --preserve-semi      Preserve unnecessary semicolons (such as right before a '}') This option      is useful when compressed code has to be run through JSLint (which is the      case of YUI for example)  --disable-optimizations      Disable all the built-in micro optimizations.NOTES  + If no input file is specified, it defaults to stdin.  + Supports wildcards for specifying multiple input files.  + The YUI Compressor requires Java version >= 1.4.  + It is possible to prevent a local variable, nested function or function    argument from being obfuscated by using "hints". A hint is a string that    is located at the very beginning of a function body like so:    function fn (arg1, arg2, arg3) {        "arg2:nomunge, localVar:nomunge, nestedFn:nomunge";        ...        var localVar;        ...        function nestedFn () {            ....        }        ...    }    The hint itself disappears from the compressed file.  + C-style comments starting with /*! are preserved. This is useful with    comments containing copyright/license information. For example:    /*!     * TERMS OF USE - EASING EQUATIONS     * Open source under the BSD License.     * Copyright 2001 Robert Penner All rights reserved.     */    becomes:    /*     * TERMS OF USE - EASING EQUATIONS     * Open source under the BSD License.     * Copyright 2001 Robert Penner All rights reserved.     */MODIFIED RHINO FILES  YUI Compressor uses a modified version of the Rhino library  (http://www.mozilla.org/rhino/) The changes were made to support  JScript conditional comments, preserved comments, unescaped slash  characters in regular expressions, and to allow for the optimization  of escaped quotes in string literals.COPYRIGHT AND LICENSE  Copyright (c) 2011 Yahoo!
