var fs  = require('fs'); 
var jsp = require("./uglify-js").parser;
var pro = require("./uglify-js").uglify;

// 批量读取文件，压缩之
function buildOne(fileIn, fileOut) {
    if (fileIn.length > 0) {
        var finalCode = [];
        var origCode = '';
        var ast = '';
        for (var i = 0,len = fileIn.length; i < len; i++) {
            origCode = fs.readFileSync(fileIn[i], 'utf8');
            ast = jsp.parse(origCode); 
            ast = pro.ast_mangle(ast); 
            ast = pro.ast_squeeze(ast);

            finalCode.push(pro.gen_code(ast), ';');
        };
    }

    fs.writeFileSync(fileOut, finalCode.join(''), 'utf8');
}
//压缩首页js
buildOne(['../lib/slides.jquery.js', '../tpl/header_notice.tpl.js'], '../compile/home.min.js');
