gulp-less
=========
A LESS plugin for Gulp
[](https://www.npmjs.com/package/gulp-less)
[](https://travis-ci.org/plus3network/gulp-less)
## Installation
```
npm install gulp-less
```
## Basic Usage
```js
var less = require('gulp-less');
var path = require('path');
gulp.task('less', function () {
return gulp.src('./less/**/*.less')
.pipe(less({
paths: [ path.join(__dirname, 'less', 'includes') ]
}))
.pipe(gulp.dest('./public/css'));
});
```
## Options
The options you can use [can be found here](http://lesscss.org/#using-less-configuration). Below is a list of valid options as of the time of writing:
- `paths`: Array of paths to be used for `@import` directives
- `plugins`: Array of less plugins ([details](#using-plugins))
The `filename` option is not necessary, it's handled automatically by this plugin. The `compress` option is not supported -- if you are trying to minify your css, use [gulp-minify-css](https://github.com/jonathanepollack/gulp-minify-css). No `sourceMap` options are supported -- if you are trying to generate sourcemaps, use [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps).
## Minifying CSS
If you want to minify/compress your css, you can use either the [gulp-minify-css](https://github.com/jonathanepollack/gulp-minify-css) plugin for gulp, or the [less-clean-css](https://github.com/less/less-plugin-clean-css) plugin for less. Examples of both are shown below:
```js
// Using a less plugin to minify css
var LessPluginCleanCSS = require('less-plugin-clean-css'),
cleancss = new LessPluginCleanCSS({ advanced: true });
gulp.src('./less/**/*.less')
.pipe(less({
plugins: [cleancss]
}))
.pipe(gulp.dest('./public/css'));
```
```js
// Using a gulp plugin to minify css
var minifyCSS = require('gulp-minify-css');
gulp.src('./less/**/*.less')
.pipe(less())
.pipe(minifyCSS())
.pipe(gulp.dest('./public/css'));
```
## Using Plugins
Less now supports plugins, which can add additional functionality like minifying css as shown above. Here's an example of how to use plugins with `gulp-less` using both the [clean-css plugin](https://github.com/less/less-plugin-clean-css) and the [autoprefix plugin](https://github.com/less/less-plugin-autoprefix).
```js
var LessPluginCleanCSS = require('less-plugin-clean-css'),
LessPluginAutoPrefix = require('less-plugin-autoprefix'),
cleancss = new LessPluginCleanCSS({ advanced: true }),
autoprefix= new LessPluginAutoPrefix({ browsers: ["last 2 versions"] });
gulp.src('./less/**/*.less')
.pipe(less({
plugins: [autoprefix, cleancss]
}))
.pipe(gulp.dest('./public/css'));
```
More info on LESS plugins can be found at http://lesscss.org/usage/#plugins, including a current list of all available plugins.
## Source Maps
`gulp-less` can be used in tandem with [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) to generate source maps for your files. You will need to initialize [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) prior to running the gulp-less compiler and write the source maps after, as such:
```js
var sourcemaps = require('gulp-sourcemaps');
gulp.src('./less/**/*.less')
.pipe(sourcemaps.init())
.pipe(less())
.pipe(sourcemaps.write())
.pipe(gulp.dest('./public/css'));
```
By default, [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) writes the source maps inline in the compiled CSS files. To write them to a separate file, specify a relative file path in the `sourcemaps.write()` function, as such:
```js
var sourcemaps = require('gulp-sourcemaps');
gulp.src('./less/**/*.less')
.pipe(sourcemaps.init())
.pipe(less())
.pipe(sourcemaps.write('./maps'))
.pipe(gulp.dest('./public/css'));
```
## Error Handling
By default, a gulp task will fail and all streams will halt when an error happens. To change this behavior check out the error handling documentation [here](https://github.com/gulpjs/gulp/blob/master/docs/recipes/combining-streams-to-handle-errors.md)
