Less for Gulp
A LESS plugin for Gulp
|Description||Less plugin for gulp|
|Node Version||>= 0.10|
|Less Version||>= 2.x|
npm install gulp-less
var less = require'gulp-less';var path = require'path';gulptask'less'return gulpsrc'./less/**/*.less'pipelesspaths: pathjoin__dirname 'less' 'includes'pipegulpdest'./public/css';;
The options you can use can be found here. Below is a list of valid options as of the time of writing:
paths: Array of paths to be used for
plugins: Array of less plugins (details)
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.
Less now supports plugins, which can add additional functionality. Here's an example of how to use a plugin with
var LessAutoprefix = require'less-plugin-autoprefix';var autoprefix = browsers: 'last 2 versions' ;return gulpsrc'./less/**/*.less'pipelessplugins: autoprefixpipegulpdest'./public/css';
More info on LESS plugins can be found at http://lesscss.org/usage/#plugins, including a current list of all available plugins.
gulp-less can be used in tandem with gulp-sourcemaps to generate source maps for your files. You will need to initialize gulp-sourcemaps prior to running the gulp-less compiler and write the source maps after, as such:
var sourcemaps = require'gulp-sourcemaps';gulpsrc'./less/**/*.less'pipesourcemapsinitpipelesspipesourcemapswritepipegulpdest'./public/css';
By default, 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:
var sourcemaps = require'gulp-sourcemaps';gulpsrc'./less/**/*.less'pipesourcemapsinitpipelesspipesourcemapswrite'./maps'pipegulpdest'./public/css';
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
