 32 | 
 33 | ## Installation
 34 | 
 35 | ```
 36 | npm install gulp-less
 37 | ```
 38 | 
 39 | ## Basic Usage
 40 | 
 41 | ```js
 42 | var less = require('gulp-less');
 43 | var path = require('path');
 44 | 
 45 | gulp.task('less', function () {
 46 |   return gulp.src('./less/**/*.less')
 47 |     .pipe(less({
 48 |       paths: [ path.join(__dirname, 'less', 'includes') ]
 49 |     }))
 50 |     .pipe(gulp.dest('./public/css'));
 51 | });
 52 | ```
 53 | 
 54 | ## Options
 55 | 
 56 | 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:
 57 | 
 58 | - `paths`: Array of paths to be used for `@import` directives
 59 | - `plugins`: Array of less plugins ([details](#using-plugins))
 60 | 
 61 | 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 a css minifier. No `sourceMap` options are supported -- if you are trying to generate sourcemaps, use [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps).
 62 | 
 63 | ## Using Plugins
 64 | 
 65 | Less now supports plugins, which can add additional functionality. Here's an example of how to use a plugin with `gulp-less`.
 66 | 
 67 | ```js
 68 | var LessAutoprefix = require('less-plugin-autoprefix');
 69 | var autoprefix = new LessAutoprefix({ browsers: ['last 2 versions'] });
 70 | 
 71 | return gulp.src('./less/**/*.less')
 72 |   .pipe(less({
 73 |     plugins: [autoprefix]
 74 |   }))
 75 |   .pipe(gulp.dest('./public/css'));
 76 | ```
 77 | 
 78 | More info on LESS plugins can be found at http://lesscss.org/usage/#plugins, including a current list of all available plugins.
 79 | 
 80 | ## Source Maps
 81 | 
 82 | `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:
 83 | 
 84 | ```js
 85 | var sourcemaps = require('gulp-sourcemaps');
 86 | 
 87 | gulp.src('./less/**/*.less')
 88 |   .pipe(sourcemaps.init())
 89 |   .pipe(less())
 90 |   .pipe(sourcemaps.write())
 91 |   .pipe(gulp.dest('./public/css'));
 92 | ```
 93 | 
 94 | 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:
 95 | 
 96 | ```js
 97 | var sourcemaps = require('gulp-sourcemaps');
 98 | 
 99 | gulp.src('./less/**/*.less')
100 |   .pipe(sourcemaps.init())
101 |   .pipe(less())
102 |   .pipe(sourcemaps.write('./maps'))
103 |   .pipe(gulp.dest('./public/css'));
104 | ```
105 | 
106 | ## Error Handling
107 | 
108 | 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)
