//引入gulp

//引入組件 
var concat = require('gulp-concat');//合并 
var jshint = require('gulp-jshint'); //js規范驗證 
var uglify = require('gulp-uglify');//壓縮 
var rename = require('gulp-rename'); //文件名命名 
var amdOptimize = require("amd-optimize"); //require優化 
var watch = require('gulp-watch'); 
//腳本檢查 gulp.task('lint', function () { 
 gulp.src('./src/js/**/*.js') 
 .pipe(jshint()) 
 .pipe(jshint.reporter('default')); 
}); 
//require合并 
gulp.task('rjs', function () { 
 gulp.src('./src/js/**/*.js') 
 .pipe(amdOptimize("main", { //require config
