自己动手打造代码压缩合并工具

时下grunt非常的火啊,用着虽然很爽,但是它的配置确实很烦。如果之前没有用过,想要一下子熟练驾驭它,有一定的学习成本,而且还要装node这个大家伙,项目之初我们选择了compiler.jar这个轻量的工具进行打包。我一直在寻思着,如何编写一键打包工具。之前呢是手工的拼接好有的js文件,做成符合compiler.jar打包文件所要求的批处理文件,然后运行这个批处理,生成我们需要的js和CSS文件。随着js文件数量的增长,纯手工拼接这些文件的地址就变得非常考验人的耐心了,而且还容易漏掉或重复某些文件,于是“一键打包工具”的编写就变得刻不容缓了。下面是一个真实的index.html文件的一部分:

<!DOCTYPE html><html><head>    <meta charset="utf-8">    <meta http-equiv="X-UA-Compatible" content="IE=edge,Chrome=1">    <meta name="viewport" content="target-densitydpi=device-dpi, initial-scale=1, user-scalable=0, maximum-scale=1">     <!--隐藏浏览器的工具栏和菜单栏,对iso系统起用-->    <!--用于PC上调式,不参与合并压缩-->    <script src="lib/data/database.js" name="noBuild"></script>    <!--Iframe加载处理-->    <script

后面还有很长,bug,活人不能被尿憋死,办法总比问题多。我是会一点php的,php在处理文件方面是很拿手的,是时候让它发挥点作用了。于是我想到了用php去自动提出index里边的js和css,然后按指定的格式生成批处理文件,在后台用静默方式运行这个批处理,最后把结果返回给显示器。这样我就可以坐享其成了。想想都有点小激动哟,于是简单的写了一个界面.

接下来就是实现功能了,先不着急编写代码,分析下需求:

1. 遍历index.html文件,提取js文件或css文件.

2. 对这文件进行过虑,因为有些是注释掉的,有些是调式用的。

3. 生成对应的批处理文件

4. 执行批处理文件

5. 显示处理结果

即然有两种情况,我就用一个工厂模式来适配,方便以后扩
