'use strict';

var gulp = require('gulp');
var less = require('gulp-less');
var cssnano = require('gulp-cssnano');
var uglify = require('gulp-uglify');
var babel = require("gulp-babel");

gulp.task('style', function() {
    gulp.src('src/styles/*.css')
        .pipe(cssnano())
        .pipe(gulp.dest('dist/styles'))
        
    gulp.src(['src/styles/*.less', '!src/styles/_*.less'])
        .pipe(less())
        .pipe(cssnano())
        .pipe(gulp.dest('dist/styles'))
});

gulp.task('script', function() {
    gulp.src('src/scripts/*.js')
        .pipe(babel({
            presets: ['es2015']
        }))
        .pipe(gulp.dest('dist/scripts'))
})

// images 图片复制
gulp.task('image', function() {
    gulp.src('src/images/*.*')
        .pipe(gulp.dest('dist/images'))
})

// html
gulp.task('html', function() {
    gulp.src('src/*.html')
        .pipe(gulp.dest('dist/'))
})

gulp.task('build', ['style', 'script','image','html'])

 gulp.watch('src/styles/*.*', ['style']);
 gulp.watch('src/scripts/*.js', ['script']);
 gulp.watch('src/images/*.*', ['image']);
 gulp.watch('src/*.html', ['html']);
