学好该死的程序
功能描述
将less文件编译成css,当有less文件发生改变自动编译less,并保证less语法错误或出现异常时能正常工作并提示错误信息。
插件安装
$ cnpm install gulp-less --save-dev
使用方法
例1:基本使用
var gulp = require('gulp'),
less = require('gulp-less'),
pump = require('pump');
gulp.task('testLess', function (cb) {
pump([
gulp.src('src/less/index.less'),
less(),
gulp.dest('src/css')
], cb)
});
例2:编译多个less文件
var gulp = require('gulp'),
less = require('gulp-less'),
pump = require('pump');
gulp.task('testLess', function (cb) {
pump([
gulp.src(['src/less/index.less','src/less/detail.less']),
less(),
gulp.dest('src/css')
], cb)
});
例3:匹配符“!”,“”,“*”,“{}”
var gulp = require('gulp'),
less = require('gulp-less'),
pump = require('pump');
gulp.task('testLess', function (cb) {
pump([
//编译src目录下的所有less文件
//除了reset.less和test.less(**匹配src/less的0个或多个子文件夹)
gulp.src(['src/less/*.less', '!src/less/**/{reset,test}.less']),
less(),
gulp.dest('src/css')
], cb)
});
例4:与插件gulp-clean-css(不会用?请参考)组合使用,实现编译、压缩一步操作
var gulp = require('gulp'),
less = require('gulp-less'),
minifyCss = require('gulp-clean-css'),
pump = require('pump');
gulp.task('testLess', function (cb) {
pump([
gulp.src(['src/less/index.less']),
less(), // 编译
minifyCss(), // 压缩
gulp.dest('src/css')
], cb)
});
